Answer:

Exercise Problem Solution

1 Find the perimeter of a triangle the sides of which are 10 in, 14 in and 15 in. P = 10 in + 14 in + 15 in = 39 in

2 A rectangle has a length of 12 cm and a width of 4 cm. Find its perimeter. P = 12 cm + 12 cm + 4 cm + 4 cm = 32 cm

3 Find the perimeter of a regular hexagon with each side measuring 8 m. P = 6(8 m) = 48 m

4 The perimeter of a square is 20 ft. How long is one side? 20 ft ÷ 4 = 5 ft

5 The perimeter of a regular pentagon is 100 cm. How long is one side? 100 cm ÷ 5 = 20 cm

Answer:

61 square feet

Step-by-step explanation:

Your rectangle has a area of A = w l

A = 4*10 = 40

The triangle has a area of A = h (b/2)

A = 7 (6/2)

A = 21

Add both for the area

Which sum is rational?<br><br> A. π + 18<br><br> B. √25 + 1.75<br><br> C. √3 + 5.5<br><br> D. π + √2
Andre45 [30]

a. 21.141 for this pi is 3.14 so you add that and 18

b. 6.75 for this one the square root of 25 is 5. you just add 5 and 1.75

c.  7.232 sqaure root of 3 is 1.73 so add those too

d.  4.5558 pi is 3.14 and square root of 2

Write 1,000,000 as a power of 10 using exponents. A) 102 B) 103 C) 106 D) 107
Vikki [24]

Answer: 10 to the 6th power

Step-by-step explanation: To write 1,000,000 as a power of 10, first notice that 1,000,000 is a whole number. This means that the exponent of our power of 10 will be positive.

To determine the value of our exponent, first write a decimal point at the end of 1,000,000. So, it would look like this.

1,000,000.

Next, count the number of places we would need to move the decimal point in order to get 1.0.

In this problem, we would need to move the decimal point 8 places in order to get to 1.0.

This means that the value of our exponent on the power of 10 will be 8.

Therefore, 1,000,000 can be written as 10 to the 6th power.

The measure of minor arc JL is 60°.
lara31 [8.8K]

We have been given an image of a circle. We are asked to find the measure of angle JKL.

We can see that angle JML is a central angle of our given circle, so measure of angle JML will be equal to measure of arc JL. So measure of angle JML will be 60 degrees.

We know that tangent of a circle is perpendicular to radius.

We can see that tangent KJ is tangent to circle at point J and tangent KL is tangent to circle at point L. This means that measure of angle KJM and angle KLM will be 90 degrees each.

We can see that JKLM is a quadrilateral. We know that all angles of a quadrilateral add up-to 360 degrees, so we can set an equation as:

\angle JKL+\angle KLM+\angle LMJ+\angle MJK=360^{\circ}

\angle JKL+90^{\circ}+60^{\circ}+90^{\circ}=360^{\circ}

\angle JKL+240^{\circ}=360^{\circ}

\angle JKL+240^{\circ}-240^{\circ}=360^{\circ}-240^{\circ}

\angle JKL=120^{\circ}

Therefore, measure of angle JKL is 120 degrees and option B is the correct choice.
