The answer is 37. You use Pythagorean theorem so you get 5 squared + b squared= 13 squared. You’d get 25+ b squared= 169. You subtract 25 from 169 and you get b squared equals 144. You square root both the b and 144 and You would get 12 for that side. Then you do Pythagorean theorem again. You do 12 squared+ 35 squared= c squared. This would turn into 144+1,225= c squared this simplifies to 1,369= c squared. You square root both sides and you get your final answer 37

A baker needs more than 120 minutes to let their dough rise.

Sedaia [141]

<u>Answer:</u>

m > 120

<u>Step-by-step explanation:</u>

<h3>How do we represent inequalities?</h3>

Inequalities are expressed using either the '>' or '<' symbols.

• The symbol '>' means "greater than". For example, 6 > 3, which means '6 is greater than 3'.

• The symbol '<' means "smaller than". For example, 5 < 9, which means '5 is smaller than 9.

In this example, if the baker needs more than 120 minutes, and <em>m</em> represents the number of minutes, then:

$\boxed{m > 120}$ .

This inequality means 'm is greater than 120'.

What is the length of one leg of the triangle? 64 cm 64 StartRoot 2 EndRoot cm 128 cm 128 StartRoot 2 EndRoot cm.

zmey [24]

Answer:

Use the Pythagorean theorem for right triangles to solve this

a^2 + b^2 = c^2 where 'a' and 'b' are the legs of the triangle and 'c' is the hypotenuse

so:

8^2 + b^2 = 17^2 solve for the second leg, b

64 + b^2 = 289

b^2 = 289 - 64= 225

b = 15

If the radius is 14cmand The perimeter of the sector is 57.32cm.<br>what is the size of the angle?

Degger [83]

Answer:

120°

Step-by-step explanation:

A sector of a circle is the portion or region of a circle enclosed by two radii and an arc. The perimeter of a the sector of a circle is given by the formula:

Perimeter of sector = $\frac{\theta}{360} *2\pi r$ + 2r

Where θ is the angle which forms the sector and r is the radius of the circle.

Given that Perimeter of sector = 57.32 cm, radius (r) = 14 cm, we can find the angle θ using:

Perimeter of sector = $\frac{\theta}{360} *2\pi r$ + 2r

$57.32=\frac{\theta}{360} *2\pi *14+2(14)\\\\57.32-28=\frac{\theta}{360} *2\pi *14\\\\29.32=\frac{\theta}{360} *2\pi *14\\\\ \frac{\theta}{360}=\frac{29.32}{2\pi *14} \\\\\frac{\theta}{360}=0.33\\\\\theta=120^o$
