Step-by-step explanation:

2500×5%=125

125×2=250

2500+250=2750$

Answer:

2756.25 This is what he will pay going into the third year.

Step-by-step explanation:

This is not as simple as it looks. Is the base number always 2500 no matter how many years go by?

Or do you compound the rent after each Year.

Simple Interest

Rent after the first year

Rent after first year = 2500 + 5%*2500

Rent after first year = 2500 + 125

Rent after first year = 2625

The rent after the second year will be the same.

Compound interest.

Rent after first year is 2625

At the end of the second year it will be 2625 + 2625*5%

Second year payment = 2625 + 2625*5/100

Second year payment = 2625 + 131.25

Second year payment = 2756.25

Answer:

Midsegment=1.7

Step-by-step explanation:

Distance formula

d = √(x2 - x1)^2 + (y2-y1)^2}

d=√(4-(-2)^2+(3-4)^2

simplify and solve

we find d=1

Now side lenght

d=√((-2-(-2))^2+(4-(-2))

d=2.44949

length of midsegment=1/2 x (2.44949+1)

1.724745

simplifies to

1.7

Step-by-step explanation:

Missing Table:

Yellow Paint ----------- Red Paint

5 ---------------------------------6

Required

Determine the quarts of yellow paints when 9 quarts of red are used

Represent Yellow with Y and Red with R.

When Y = 5 and R = 6, we have the following:

[tex]Y : R = 5 : 6[/tex]

Represent as a fraction

[tex]\frac{Y}{R} = \frac{5}{6}[/tex]

When R = 9 and Y is unknown, we have the following:

and

[tex]Y : R = Y : 9[/tex]

Represent as a fraction

[tex]\frac{Y}{R} = \frac{Y}{9}[/tex]

Since the given parameters re[resent a direct variation between both paints, we can equate both fractions to solve for Y

[tex]\frac{5}{6} = \frac{Y}{9}[/tex]

Multiply through by 9

[tex]9 * \frac{5}{6} = \frac{Y}{9} * 9[/tex]

[tex]9 * \frac{5}{6} = Y[/tex]

[tex]3 * \frac{5}{2} = Y[/tex]

[tex]\frac{15}{2} = Y[/tex]

[tex]7\frac{1}{2} = Y[/tex]

[tex]Y = 7\frac{1}{2}[/tex]

Hence, [tex]7\frac{1}{2}[/tex] quarts of the yellow paints is required

Answer:

18.6cm (rounded to 3 s.f.)  

Step-by-step explanation:

You can actually figure out the two bases of the triangles based on the Pythagoras theorem where the slant length of a 90° triangle is [tex]\sqrt{a^{2} + b^{2} }[/tex] where a is one of the bases and b is the other length that is 90° perpendicular to a.

So this means:

[tex]\sqrt{6^{2} + base^{2} }[/tex] = 8cm

6² + base² = 64cm

36 + base² = 64

base² = 64-36

          = 28

base = [tex]\sqrt{28}[/tex]

        ≈ 5.2915 (5 s.f.)

So the two bases are roughly 5.2915, and the middle base is part of a rectangle, so it has the same length as the rectangle's length, which is 8cm.

Thus, x = 5.2915 + 5.2915 + 8

            = 18.6cm (rounded to 3 s.f.)

For the first 30 minutes, we will have a line with a given steepness, this will represent the 30 minutes riding at a fast pace.

Then he stops for 20 minutes, we will represent this with a constant line.

Then he again moves for another 30 minutes, but with a slower pace than in the first 30 minutes, then this line will be less steep than the first line.

A sketch of this situation can be seen below.

Answer:

48.7

Step-by-step explanation:

This is a right triangle, so let's use Pythagorean Thearum to solve.

a2+b2=c2 substitute the numbers in. [tex]35^2+b^2=60^2\\[/tex] = 1,225+b^2=3,600

subtract 1225 from 3600. 3600-1225=2375. Now we have to find the square root. [tex]\sqrt 2375[/tex] equals about 48.7

to double-check: 1225 + 2375 = 3600 this equation holds true. so 48.7 is the answer.

Answer:

-3.8

Step-by-step explanation:

The temperature when Daria goes to bed was -3.8° F.

To subtract means to take away from a group or a number of things. When we subtract, the number of things in the group reduces or becomes less.

Given that, When Daria gets to school, the temperature is 5.7 °F. The temperature changes by -9.5 °F by the time she goes to bed.

5.7 - 9.8 = -3.8

Hence, The temperature when Daria goes to bed was -3.8° F.
