5 hours after noon, darmian is 17 miles closer to the stadium than paisley

Step-by-step explanation:

At noon, Damian is 383 miles away from the stadium and paisley is 315 miles away from the stadium.

Now, we are told that damians speed is 59 mph while paisley's speed is 42 mph.

At t hours after noon, their distance covered will be;

Damian; D = 59t

Paisley; P = 42t

This is because distance = speed × time

Now, 5 hours after noon, their respective distance covered will be;

D(5) = 59 × 5 = 295 miles

P(5) = 42 × 5 = 210 miles

This means that;

distance of Damian from the stadium is; 383 - 295 = 88 miles

Distance of paisley from the stadium is;

315 - 210 = 105 miles

Difference in their distances to the stadium = 105 - 88 = 17 miles

Thus, 5 hours after noon, darmian is 17 miles closer to the stadium than paisley

If these two shapes are similar, what is the measure of the missing length b?

Answers

Answer:

B = 7mm

Step-by-step explanation:

This is probably an enlargement problem.

To solve this:

the blue triangle has all of it's measurements you need. Let's start with that.

6/36 =

We know that one side, the bottom side of the green triangle is 42mm.

6/36 = b/42

We could simplify 6/36 into 1/6

1/6 = b/42

AHA! the denominators are easy! 6 times 7 is equal to 42, so 1 times 7 should equal b!

1/6 = 7/42

Check:

6/36 = b/42

36b = 6*42

36b = 252

   b = 252/36

   b = 7

So yes! B is 7 mm. Pls mark me brainliest, as I never have a single brainliest.

Luciana is adding water to a pool at a constant rate. Before she added any water, the pool had $12,000$ gallons of water. Luciana is adding $9$ gallons of water each minute.

Which equation represents the total number of gallons of water in the pool, $w$ , after Luciana adds water for $m$ number of minutes?

Answers

Answer:

T(m) = 12,000 gallons + (9 gallons/ minute)m

Step-by-step explanation:

This is a linear function with beginning value 12,000 gallons and unit rate of increase 9 gallons/minute:

T(m) = 12,000 gallons + (9 gallons/ minute)m

16 ÷ 22 + (6 x 2) - 8

Answers

I did the PEMDAS method (P= parentheses, E= exponents, M= multiplication, D = Division, A= addition, S = subtraction.)

First I did what’s inside the parentheses, (6x2) and got 12.

Then I divided 16 by 22 and received 0.72.

I added 0.72 with 12 and the result was 12.72.

Last step was to subtract 12.72 - 8 and that equals 4.72
16 ÷ 22 + (6 x 2) - 8 = 4.72

Find the slope of the line passing through the points (-9,4) (8,4)

Answers

Answer:

slope = 0  

Step-by-step explanation:

1) Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], to solve for the slope. Use the x and y values of the given points, substitute them into the formula, and solve like so:

[tex]m = \frac{(4)-(4)}{(8)-(-9)} \\m = \frac{4-4}{8+9} \\m = \frac{0}{17} \\m = 0[/tex]

Thus, the slope is 0.

Find the Circumference area of the circle. Use 3.14 for pi. Round tithe nearest hundredth if necessary

Answers

Answer:

351.68cm

Step-by-step explanation:

Using the attached diagram

Radius of the circle = 56cm

Circumference of the circle =2πr

r is the radius of the circle

Circumference of the circle =2(3.14)(56)

Circumference of the circle = 6.28 *56

Circumference of the circle  = 351.68cm

Hence the circumference area of the circle is 351.68cm
