The sum of three numbers is 62. The second number is equal to the first number diminished by 4. The third number is four times the first. What are the numbers? Which three expressions could be used to represent the numbers?
A n; n - 4; 4n
B n; 4 - n; n + 4
C n; n/4; n + 4

Answer:

B; or "a > -2"

Step-by-step explanation:

If solved by order of operations:

- divide both sides by 13

- 13 will cancel out on the left side and the when -26 will be divided by 13 the answer will be "-2"

- This leaves with the answer of "x > -2"

Hope this helps!

Answer:

23

Step-by-step explanation:

In this question, we want to evaluate the expression "9z-4" for z=3.

This means, we want to calculate the result when we substitute the z in this expression for 3.

So we have: 9(3)-4, which is equal to 23.

Answer:

45

Step-by-step explanation:

6+30+48-1-9=45

Answer:

Step-by-step explanation:

we have to find if the series have a constant of proportionality by dividing the value of y by each value of x

1)

100 : 2 = 50

200 : 4 = 50

300 : 6 = 50

400 : 8 = 50

ok = y

2)

0.60 : 4 = 0.15

1.20 : 8 = 0.15

1.44 : 12 = 0.12

no = n

3)

0.15 : 1 = 0.15

0.3 : 2 = 0.15

0.45 : 3 = 0.15

0.6 : 4 = 0.15

ok = y

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

Answer:

Step-by-step explanation:

Japan 80.09 = 16.018

Switzerland 75.81 = 15.162

Answer:

In Japan, the average ticket costs $17.73.

In Switzerland, the average ticket costs $13.45

Step-by-step explanation:

80.09-75.81=3j+2s-(2j+3s)

4.28=j-s

So a ticket from Japan costs $4.28 more than a ticket from Switzerland. so we can write the equation:

3s+2(s+4.28)=75.81

5s=67.25

s=13.45, j=13.45+4.28=17.73

If you look at the chart  you can see 20 mins and then if you go to the point of 25 which would be between ( in the middle) of 20 and 30, then you would go up to the empty point that is followed up by the 20 and 30 and as you can see you get 380, so your first answer for number 1 would be 380 gallons

The second question um looking at the chart again if you would go to 35 then go up you can see 500 is how 35 Is your answer (about 35 mins)

Answer:

Step-by-step explanation:

To find the volume of 11 x 2, you need to know the third dimension, as volume is a three-dimensional measure. Assuming you mean the dimensions of a rectangular solid, you would need to know the height or depth of the object to calculate the volume. As for screen time for children, the American Academy of Pediatrics recommends limiting it to one hour per day for children aged 2-5 and to no more than two hours per day for children aged 6 and older. Engaging in creative play can help children develop important skills, such as problem-solving and communication, while excessive screen time has been linked to negative effects on cognitive and social development.

Answer:

The answer is 22

Step-by-step explanation:

You have to multiply the base times the height (2 x 11) Doing that will get you 22 ft.

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Answer:

A ≈ 312.1

Step-by-step explanation:

\(A = \pi r(r+\sqrt{h^2 + r^2})\)

r = 5

h = 14

\(A = \pi 5(5+\sqrt{14^2+5^2})\)

A = 312.055478161

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

Answer:

y-intercept : 8

slope: -1/2

equation:   \(y = -\dfrac{1}{2}x + 8\)

Step-by-step explanation:

The y-intercept is where the line crosses the y axis and you can see it crosses at y = 8 (when x =0)

Slope of the line can be found by the formula (y2-y1) / (x2-x1)  where 9x1, y1) and (x2, y2) are two points on the line

Let's take the points (0, 8) and (10, 3) the two extreme points on the line

Slope = (3 - 8) / (10 - 0) = -5 / 10 = - 1/2

Equation of a line in slope intercept form is

y = mx + c

where m is the slope  

b is the y intercept

The equation of the line is therefore

\(y = -\dfrac{1}{2}x + 8\)

Answer:

Y-intercept = 8

Slope = -1/2t

Equation = y =-1/2x+8

Step-by-step explanation:

When x = 0, y = y-intercept.

Therefore, the y-intercept is 8.

We can find the slope using the formula y2-y1 / x2-x1 = m.

Let's use the points (0,8) and (4,6)

6-8 / 4-0 = m;

m = - 1/2.

Given that the generic formula is y=mx+b, and m-slop and b=y-intercept, we have:

y = -1/2x+8.

The solution is : The amount Pearl was charged in interest for billing cycle = $19.8

Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.

here, we have,

Starting balance of Pearl for first 10 days of her 30 days billing cycle =$1120

Purchase made = $ 340

Total Balance after purchase made = $1120 + $340

                                                          = $1460

Payment made after 10 days = $580

Balance for last 10 days = $1460 - $580

                                       = $880

Credit Card APR = 27% Annually

Credit Card APR = 2.25% monthly.

Amount charged as an interest for billing cycle = 880 × 2.25%

                                                                              = 880 × 0.0225

                                                                              =  $19.8

Hence, The amount Pearl was charged in interest for billing cycle = $19.8

complete question:

Pearl has a credit card that uses the adjusted balance method. For the first 10 days of one of her 30-day billing cycles, her balance was $1120. She then made a purchase for $340, so her balance jumped to $1460, and it remained that amount for the next 10 days. Pearl then made a payment of $580, so her balance for the last 10 days of the billing cycle was $880. If her credit card's APR is 27%, which of these expressions could be used to calculate the amount Pearl was charged in interest for the billing cycle?

Step-by-step explanation:

Since the question implies his truck travels at a constant distance per gallon, we can set up the following proportion to find how much father his truck can go.

Let \(x\) represent how much farther his truck can go, in kilometers:

\(\frac{2}{76}=\frac{1.5}{x}\)

Cross-multiplying, we get:

\(2x=76\cdot 1.5,\\x=\frac{76\cdot 1.5}{2}=\boxed{57\:\mathrm{km}}\)

Answer:

Step-by-step explanation:

2 ÷ 76 = 1.5 ÷ d

Answer:

676/27

Step-by-step explanation:

= (1/3)^3 + (-5)^2

= (1^3/3^3) + 25

= 1/(3^3) + 25

= 1/27 + 25

= 1/27 + 675/27

= 676/27

∴ a^3 + b^3 = 676/27

The value of the given expression a³+b² when the value of a and b are 1/3 and -5 is 25.037.

Given the value of a and b as 1/3 and -5, respectively.
To evaluate the value of a³+b², substitute the value of a and b in the given expression. Therefore, the value will be,

\(a^3 + b^2\\\)

Substitute the value in the expression,

\(=\left ( \dfrac{1}{3} \right )^3+(-5)^2\\\\\\=\left ( \dfrac{1}{27} \right )+25\\\\\\= 25\frac{1}{27}\ \ \rm or\ \ 25.037\)

Hence, the value of a³+b² is 25.037.
