For 37 you have a 90° angle, so you add 6x + 14 and 3x + 29 and get 9x + 43 and now set this equal to 90 and solve for x, and then plug x into the original equation for each angle to solve

Smith High School offers a baseball camp that is $75 for 4 days of camp and a basketball camp that is $100 for 5 days of camp. W

Anastasy [175]

For the baseball camp, you would be paying $18.75 per day. For the basketball camp, you would be paying $20 per day. Judging by the prices, you would be more likely to have a better price for the baseball camp by 1.25. Yes, it isn't that much, but it's still worth it. Hope it helped!

The diameter of a truck tire is 22inches Approximately how fat will the truck have traveled after 5 rotations of these tires

kvasek [131]

Answer:

The truck have travelled 345.5 inches after 5 rotations of the tires

Step-by-step explanation:

Given:

Diameter of the tyre= 22 inches

Number of rotations= 5

To find:

Distance travelled after 5 rotations=?

Solution:

We have given with diameter,

So let radius be r

r= $\frac{diameter}{2}$

$r=\frac{22}{2}$

r=11 inches

The distance covered by one rotation is given by circumference

Circumference = $2\pi r$

Substituting the values, we get

Circumference = $2\times\pi\times r$

Circumference = $2\times\pi\times 11$

Circumference = $2\times\3.14\times 11$

Circumference = $6.28\times 11$

Circumference = 69.11

Now for 5 rotation,

Distance travelled = $5\times(\text{circumference value})$

Distance travelled = $5\times(69.11)$

The truck will travel 345.5 inches.

The length of a rectangle is 3 cm greater than the width of the rectangle.

professor190 [17]

Answer:

B) 8 cm

Step-by-step explanation:

Hello, I can help you with this

according to the question

The length of a rectangle is 3 cm greater than the width of the rectangle.

convert this into algebraic terms

Step 1

do the eqution

Let

W,width

L,Length

The length of a rectangle(L) is(=) 3 cm greater than the width (W+3) of the rectangle.

note:3 cm greater than the width (W+3) means that you need add 3 to the width to obtain the length

L=W+3 equation(1)

the area of the rectangle is 40 square cm

Let

A,Area

Area= 40 cm

A=40

also,A=L*W

40=L*W equation(2)

Step 2

solve the equations

L=W+3 equation(1)

40=L*W equation(2)

replace the value of L from equaiton (1) into equation (2)

$40=(W+3)*W\\40=W^{2} +3W\\W^{2} +3W-40=0\\W^{2}+3W-40=0\\\\use cuadratic\\\\w=\frac{-b+-\sqrt{b^{2}-4ac } }{2a}\\\\w=\frac{-3+-\sqrt{3^{2}-4*1*-40 } }{2*1}\\w=\frac{-3+-\sqrt{169} }{2}\\$

we are looking for a distance, so we need the positive valur only.

$w=\frac{-3+-\sqrt{169} }{2}\\\\w=\frac{-3+13}{2}\\ w=5\\$

Step 3

Now, replace the value of W into equation (1) to obtain the length

L=W+3 equation(1)

L=5+3

L=8

so, the length is 8 cm, B) 8 cm

Have a nice day.
