Answer:
4
Step-by-step explanation:
When we want to find a quotient, what we do is that we switch the numerator and the denominator of the second fraction and then we multiply the two resulting fractions. If we have \(\frac{6}{7}\) and \(\frac{3}{14}\), doing this we would have:
\(\frac{6}{7}(\frac{14}{3})=\frac{84}{21} = \frac{28}{7} =\frac{4}{1}=4\)
Thus, the right answer is 4.
Brittany went grocery shopping , she spent 4/7 of her money on fresh foods. she spent 2/3 of the remainder of her money on frozen foods. if she spent 22$ on frozen foods. how much money did she spend on fresh foods?
Answer:
$44
Step-by-step explanation:
Let the total amount of money be represented by Y
Amount spent on fresh food =
\( \frac{4}{7} \times y\)
Remainder =
\(y - \frac{4}{7}y = \frac{3}{7} y\)
Amount spent on frozen foods = two-thirds of remainder = $22
\( = \frac{2}{3} \times \frac{3}{7} y = \frac{2}{7} y\)
\(\frac{2}{7} y = 22 \\ y = 22 \times \frac{7}{2} \\ y = 77\)
The total amount for grocery shopping is $77
Therefore, Brittany spent $44 on fresh foods
\( = \frac{4}{7} \times 77 \\ = 4 \times 11 \\ = 44\)

Step-by-step explanation:
a = \(\sqrt{12^2 -9^2} = \sqrt{144-81} = \sqrt{63}\)
We use the minus because we are searching a leg.
A leg is always shorter than the hypotenuse
Answer:
a = 7.9 or a = √63
Step-by-step explanation:
a² + b² = c²
(The two shorter sides of a triangle are always a and b while the longer side will always be c)
So, here the longer side of this triangle is 12 and the shorter sides are 9 and a (unknown).
The equation is: a² + 9² = 12²
But to find the value of a, the formula will be 12² - 9² = a²
12² - 9² = a²
144 - 81 = a²
63 = a²
the square root of 63 = 7.9 so that means a = 7.9

Use the function rule \(f\)(x)=3\(x\)-2. Find the output \(f\)(1.5).
Answer:
To find the output of the function f(x) = 3x - 2 when x = 1.5, we simply substitute 1.5 for x in the function rule and simplify:
f(1.5) = 3(1.5) - 2
f(1.5) = 4.5 - 2
f(1.5) = 2.5
Therefore, the output of the function f(x) when x = 1.5 is 2.5.
Answer:
f(x)- x = 1.5 is 2.5.

company A 12 tigers for 33.24
company b 16 tigers for 44.80
company c 15 tigers for 41.10
Answer: c
Step-by-step explanation:
33.24 / 12 = 2.77
44.80 / 16 = 2.80
41.10 / 15 = 2.74
(/ means divide)
Answer:
Company C has the lowest cost per tiger.
Step-by-step explanation:
1. Divide the cost by the amount of toys.
-The cost for one tiger in Company A is 2.77 (33.24 ÷ 12 = 2.77)
-The cost for one tiger in Company B is 2.8 (44.80 ÷ 16 = 2.8)
-The cost for one tiger in Company C is 2.74 (41.10 ÷ 15 = 2.74)
2. Compare the quotients of all the companies.
Once you compare the costs, you will see that Company C has the lowest cost per tiger.

Which statements are true for the image below? Check all that apply.
A triangle has angles C, A, 33 degrees. The exterior angle to angle with measure of 33 degrees is D, the exterior angle to A is B, the exterior angle to angle C is 128 degrees.
Measure of angle B = measure of angle C + 33 degrees
Measure of angle B = 180 degrees minus (measure of angle D + 128 degrees)
Measure of angle B = 360 degrees minus (measure of angle D + 128 degrees)
Measure of angle D + measure of angle B + 128 degrees = 360 degrees
180 degrees = measure of angle D + measure of angle B + 128 degrees = 360 degrees
Measure of angle D = 360 degrees minus 33 degrees
Measure of angle D = 180 degrees minus 33 degrees
Measure of angle B = measure of angle D + 128 degrees
The statements that are true for the image below are:
A. m∠B = m∠C + 33° (exterior angle theorem)
C. m∠B = 360° - (m∠D + 128°) (sum of exterior angles)
D. m∠D + m∠B + 128° = 360° (sum of exterior angles)
G. m∠D = 180° - 33° (angles on a straight line)
The statements that are true for the image below are:
A. m∠B = m∠C + 33° (exterior angle theorem)
C. m∠B = 360° - (m∠D + 128°) (sum of exterior angles)
D. m∠D + m∠B + 128° = 360° (sum of exterior angles)
G. m∠D = 180° - 33° (angles on a straight line)
What is the Triangle Sum Theorem?The triangle sum theorem states that, all the interior angles of a triangle will give a sum of 180°.
Given is a figure we have to choose the correct statements from the options given,
We know that,
Angles on a straight line sum up to 180°.
Sum of all exterior angles of any polygon = 360°.
Therefore, the statements that are true for the image below are:
A. m∠B = m∠C + 33° (exterior angle theorem)
C. m∠B = 360° - (m∠D + 128°) (sum of exterior angles)
D. m∠D + m∠B + 128° = 360° (sum of exterior angles)
G. m∠D = 180° - 33° (angles on a straight line)

An architect plans to build an extension to Meiling's rectangular deck. Let x represent the increase, in meters, of her deck's length. The expression 2(x + 7) represents the area of the deck, where 2 is the width, in meters, and (x + 7) represents the extended length, in meters. Use the Distributive Property to write an expression that represents the total area of Meiling's new deck.
The expression should be 2x + 14
Calculation:Since 2 is the width, in meters, and (x+7) represents the extended length, in meters.So, area is:
\(A = 2(x+7)\)

You survey students in your class about the number of movies they watched last month. The results are shown in the table. 7,5,14,5,6,9,10,12,15,4,5,8,11,10,9,2 A new student joins the class who watched 21 movies last month. Is 21 an outlier? How does including this value affect the measures of center and the measures of variation? Explain. Round your answers to the nearest hundredth, if necessary.
The data set
{7,5,14,5,6,9,10,12,15,4,5,8,11,10,9,2}
sorts to
{2,4,5,5,5,6,7,8,9,9,10,10,11,12,14,15}
There are n = 16 items in that set. The middle-most item is between slot n/2 = 16/2 = 8 and slot 9.
The value in slot 8 is 8
The value in slot 9 is 9
The midpoint is (8+9)/2 = 17/2 = 8.5 which is the median.
The mean is found by adding up all of the values and dividing by n = 16.
(2+4+5+5+5+6+7+8+9+9+10+10+11+12+14+15+21)/16 = 8.25
We have
mean = 8.25median = 8.5mean < median indicates the data is slightly skewed left.
------------------------
Let's break the sorted set into two smaller halves
L = lower half
L = stuff smaller than the median
L = {2,4,5,5,5,6,7,8}
U = upper half
U = stuff larger than the median
U = {9,9,10,10,11,12,14,15}
The median of set L is 5, which is the value of Q1 aka first quartile.
The median of set U is 10.5 aka Q3.
The min and max are the smallest and largest items (2 and 15 currently).
Here's the five-number-summary of the original data set
min = 2Q1 = 5median = 8.5 (aka Q2)Q3 = 10.5max = 15Let's compute the interquartile range
IQR = Q3 - Q1 = 10.5 - 5 = 5.5
Then,
LF = lower fence = Q1 - 1.5*IQR = 5 - 1.5*5.5 = -3.25UF = upper fence = Q3 + 1.5*IQR = 10.5 + 1.5*5.5 = 13.25Rule: If a value is between LF and UF, then it is not an outlier. Otherwise we have an outlier.
There aren't any values smaller than LF since 2 is the min. But there are two values larger than UF. Those two values are 14 and 15.
Therefore, 14 and 15 are considered outliers in the original set.
------------------------
What happens when we introduce 21 to the set?
Sorted set = {2,4,5,5,5,6,7,8,9,9,10,10,11,12,14,15,21}
Here's the five-number-summary
min = 2Q1 = 5median = 9 (aka Q2)Q3 = 11.5max = 21The IQR this time is 11.5-5 = 6.5, and,
LF = lower fence = Q1 - 1.5*IQR = 5 - 1.5*6.5 = -4.75UF = upper fence = Q3 + 1.5*IQR = 11.5 + 1.5*6.5 = 14.75In this case, 14 is no longer an outlier. It's just barely to the left of UF. The value 15 is still an outlier and 21 is most definitely an outlier as well.
As you can see, the new outlier 21 pulls the measure of center to the right. Think of it like a pull of a magnet. Also, the 21 spreads the data out further so the measure of variation increases.
Side note: if you need to calculate the standard deviation, I recommend using a calculator that has that specific function.

Dillon says that 4b and -2b are not like terms because 4b is positive and -2b is negative. Is he correct? Explain.
The value of the equation is 4b ≠ -2b and they are not like terms
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first term be p = 4b
Let the second term be q = -2b
Now , the value of b can be negative or positive
Substituting the values in the equation , we get
when b = positive
The value of p is also positive and the value of q is negative
when b = negative
The value of p is negative and value of q is positive
Therefore , the values of p and q cannot be equal and they are not like terms
Hence , the equation is 4b ≠ -2b they are not like terms

Allison is buying binders for school. Small binders cost $3 each, and large binders cost $5 each. If Allison needs to buy at least 12 binders and has no more than $45 to spend, what is the maximum number of large binders she can buy?From the given data we can form the equation let n1 and n2 are the numbers of the small and the large binders and Sb and Lb are the cost of each binder.
n₁Sb + n₂Lb = 45 ................................1
n₁ + n₂ = 12
Now put the value of n₁ in equation 1.
( 12 - n₂ )3 + 5n₂ = 45
36 - 3n₂ + 5n₂ = 45
