Step-by-step explanation:

Answer 2
Answer:

A = √3 cm²

Step-by-step explanation:

Hi there !

use formula for area of equilateral triangle

[tex]A=\frac{s^{2} \sqrt{3}}{4}[/tex]

If a track is 400 meters around, how many laps around the track would it take to run 3.1 miles round to the nearest tenth

Answers

Answer:

Step-by-step explanation:

12.5

Number of laps in given distance is 12.5 laps.

Given:

Length of a track = 400 meter

Total distance = 3.1 miles

Find:

Number of laps in given distance

Computation:

We know that

1 miles = 1609.34 meter

So,

Total distance = 3.1 miles

Total distance = 3.1 × 1609.34

Total distance = 4988.954

Number of laps in given distance = 4988.954 / 400

Number of laps in given distance = 12.4723

Number of laps in given distance = 12.5 laps (Approx.)

5. Average (missing value). The temperature at the top of Mt. Hood in Oregon was recorded for 5 straight days. For the first four days, the temperatures were 32°, 30°, 22°, and 10°, but a researcher lost the value of day #5. If the average temperature over the 5 days was 19.8°F, what is the missing temperature of day #5?

Answers

Answer:

5°F

Step-by-step explanation:

Given that the average is obtained from;

Average = sum of scores / number of scores

Average temperature = 19.8°F

Let the temperature of the fifth day be x

Hence;

19.8 = 32 + 30 + 22 + 10 + x/5

19.8 = 94 + x/5

x= (5×19.8) -94

x= 5°F

Write an equation in point-slope form of the line that passes through the given point and with the given slope m.
(-8,7), m = 4

Answers

Step-by-step explanation:

y-y1=m(x-x1)

y-7=4(x+8)

y-7=4x+32

4x-y=-39

Answer:

y = 4x + 39

Step-by-step explanation:

The line passes through point (-8,7) and;Has a slope (m) = 4

Let's take another point (x,y) on the line.

Slope (m) = change in y ÷ change in x

∴ m = [tex]\frac{y - 7}{x - -8} = 4[/tex]

y = 4x + 32 + 7

y = 4x + 39

A circular pool has an area of approximately 154 square feet. To the nearest foot, how much fencing is needed to completely surround the pool?

Answers

Given parameters:

Area of pool = 154ft²

Unknown:

The circumference or perimeter of the pool = ?

Solution:

The amount of fencing needed for the pool is the same as the circumference of the pool or the perimeter of the pool.

To solve this problem, we need to find the radius from the given area.

    Area of a circle  = π r²

        154  = π r²

           r² = [tex]\frac{154}{3.142}[/tex]   = 49

                    r  = 7ft

Now the circumference of a circle = 2 π r

                                                         =  2 x π x 7

                                                         = 44ft

The circumference of the circle is 44ft

Answers

Given :

The original price of the jeans was $56.

The store had marked them down by 25 percent and Seema had a 20 percent off coupon as well.

To Find :

The price of the jeans before tax.

Solution :

Discount offered by store :

Discount = 0.25×56 = $14 .

Selling price = $( 56 - 14 ) = $42 .

Discount offered through coupon on selling price :

Discount = 0.20×42 = $8.4 .

Final price = $( 42 - 8.4 ) = 4= $33.6 .

Therefore, the price of the jeans before tax is $33.6 .

Hence, this is the required solution.

33.60
