Answer:

1.05

Step-by-step explanation:

it is 105 divided by 1000

Answer:

0.105 metres

Step-by-step explanation:

105 divided by 1000

The measure of the angles for the similar triangles are ∠G = 105°; ∠H = 55° and ∠I = 20°

Two triangles are said to be similar if the ration of their corresponding sides are in the same proportion. Also, all their corresponding angles are congruent with each other.

From the diagram shown:

∠X + ∠Y + ∠Z = 180° (sum of angles in a triangle)

20 + 105 + ∠Z = 180

∠Z = 55°

Since triangle XYZ and triangle GHI are similar, hence:

∠X = ∠G = 105°; ∠Z = ∠H = 55° and ∠Y = ∠I = 20°

The measure of the angles are ∠G = 105°; ∠H = 55° and ∠I = 20°

Answer:

36 cm

Step-by-step explanation:

If the archaeologist found a fossil whose length is 489.44 inches, using the conversion table, the length in feet, to the nearest tenth, is 40.8 feet.

The conversion table refers to the tabulated standard units of measurement, showing temperature, length, area, volume, weight, and metric conversions

For instance, the conversion table shows that 12 inches equal 1 foot.

The length of the fossil = 489.44 inches

12 inches = 1 foot

489.44 inches = 40.8 feet (489.44 ÷ 12)

Thus, using the conversion table, which relies on multiplication or division operations using the conversion factors, the length in feet of the fossil is 40.8 feet.

Answer:

(9\(\frac{1}{2}\), 5\(\frac{1}{2}\)) or (9 1/2, 5 1/2)   (same things, just typed two different ways)

Step-by-step explanation

  I can't remember the midpoint formula so I'll use a different method to get the midpoint.  

    since the ratio of a midpoint is 1:1 and that as a fraction is 1/2, we can take these coordinates and designate which one is first and which one is second (12, 2) will be my second and (7,9) will be my first. The formula I will use will be \(\frac{m}{m+n} (second X, - first X) + first x\), so 1/2( 12 - 7) +7. now distribute the 1/2 to both the numbers  \(\frac{1x12}{2} -\frac{1x7}{2} + 7 \\ \\ 12/2 -7/2 = 5/2 + 7 = 9.5\)  or \(9\frac{1}{2}\). The same works with the Y values, which would equal up to 5.5 or 5 \(\frac{1}{2}\)

Additional comment

The given equation is in "general form", so that is the form of the equation we have given as the answer. This form is convenient in that the general form equation for a line through the origin, ax+by=0, is easily translated to make it pass through a point (h, k): a(x -h) +b(y -k) = 0. Eliminating parentheses puts the equation back into general form.

We can conclude that the equation of the circle is (x - 3)² + (y + 6)² = 32, where (3, -6) is the center and 4√2 is the radius. Option 3 and 6 are correct  options.

Based on the information given, we know that circle has its center at the point (3, -6) and a radius of 4√2. We also know that the point (-1, -2) and (4, -0.5) are on the circle.

Using the distance formula, we can confirm that the distance between the center of the circle and each of these points is indeed 4√2.

This equation can be simplified to x² - 6x + y² + 12y + 1 = 0 by expanding and combining like terms. This is the equation of circle , and any point that satisfies this equation will be on the circle. Option 3 and 6 are correct  options.

Answer:

5/y^3

Step-by-step explanation:

which expression is equivalent to 5y^-3

for example a^-1 = 1/a

5y^-3 = 5/y^3

You have the following number

√27

In order to determine which letter best represent the previous number, you take into account the following square roots:

√25 = 5

√36 = 6

Then, you can consider that √27 is a number in between 5 and 6, because √27 in anumber in between √25 and √36.

The only letter that is in between 5 and 6 on the number line, is the letter C.

Hence, letter C best represents √27

x = 65

Step-by-step explanation:

the sum of the interior angles of a quadrilateral = 360°

sum the angles and equate to 360

x + 95 + 118 + 82 = 360

x + 295 = 360 ( subtract 295 from both sides )

x = 65

Answer:

Option 2.

Step-by-step explanation:

The first term is already given as -2.

Therefore, the options 1 and 4 are wrong.

The nth term has 3 multiplied.

-2 × 3 = -6

-6 × 3 = -18

-18 × -54

The answer is not option 3, because that sequence has no common difference or ratio.

Therefore, the answer is option 2.

Complete Question:

Leslie placed this ad in Collector Car Monthly.

1957 Chevrolet Nomad station wagon. Tropical

Turquoise, 6 cyl. auto, PS, PW, AM/FM, repainted,

rebuilt transmission, restored two-tone interior.

Mint! Moving, sacrifice, $52,900. 555-4231

(a) If the publication charges $48 for the first three lines and $5 for each extra  line, how much will this ad cost Leslie?  

(b) b. Ruth buys the car for 8% less than the advertised price. How much does she pay?

(c) Ruth must pay her state 6% sales tax on the sale. How much must she pay in sales tax?

Answer:

\(Total = \$53\)

\(Ruth = \$48668\)

\(Sales\ Tax = \$2920.08\)

Step-by-step explanation:

Given

\(Ad = 4\ lines\)

\(Charges: \$48\) --- First 3 lines

\(Additional: \$5\) -- Extra lines

Solving (a) : Determine the total charge

The ad has 4 lines. This means that 3 of the 4 lines will be charged at $48 (in total) while the extra line will be charged at $5 per line

So, the total charge is calculated as:

\(Total = 3\ lines + 1\ line\)

\(Total = \$48 + 1 * \$5\)

\(Total = \$48 + \$5\)

\(Total = \$53\)

Solving (b): How much does Ruth pay?

From the ads, the price of the car is:

\(Price = \$52,900\)

And Ruth pays 8% less.

This means that she pays 92% (i.e. 100% - 8% = 92%)

So, the calculation is:

\(Ruth = 92\% * Price\)

\(Ruth = 92\% * \$52900\)

\(Ruth = \$48668\)

Solving (c): The sales tax

\(Sales\ Tax = Sales\ Tax\% * Amount\ Paid\)

\(Sales\ Tax = 6\% * \$48668\)

\(Sales\ Tax = \$2920.08\)

There will be approximately 6,825,000 bacteria present at midnight.

Since the count of the bacteria triples every 20 minutes, we can use exponential growth to model the situation.

Let N(t) be the number of bacteria at time t. We know that:

N(t) = N0 * 3^(t/20)

where N0 is the initial number of bacteria.

Since we know that at 1 p.m., there were 5000 bacteria present, we can substitute N0 = 5000 and t = 11 hours (since 1 p.m. to midnight is 11 hours) into this equation:

N(11) = 5000 * 3^(11*60/20)

N(11) = 6,825,000

This model can be used to determine the bacterial population at any time as long as the rate of tripling every 20 minutes remains constant. Any changes that may affect the growth rate (such as antibiotic interventions or environmental factors) will not be accounted for in this model and may affect its accuracy.

The graph of the inequality is attached in the solution.

Given is an inequality, 2y > x-2, we need to graph it,

So, considering this as, 2y = x-2

Solving like a linear equation to get the points to plot,

So,

Put y = 0,

0 = x - 2

x = 2

(2, 0)

Put x = 0,

2y = 0-2

y = -1

(0, -1)

Hence the two points from which the graph will pass are (2, 0) and (0, -1).

Now, since the inequality has a > sign so the shaded area will be above the line and the line will be dotted.

Answer:

the answer is y=−1/5x−4

Answer: \(y=-\frac{1}{5} x+4\)

Step-by-step explanation:

To put something in slope-intercept form you must isolate y

So let's solve for y

Step 1: Subtract 3x from both sides

\(3x-3x+15y=60-3x\\15y=-3x+60\)

Step 2: Divide both sides by 15 and simplify

\(\frac{15y}{15} =\frac{-3x}{15} +\frac{60}{15} \\y=-\frac{1}{5} x+4\)
