Answer:

70 degrees = a

Step-by-step explanation:

Triangle= 180 degrees.

Therefore, since a and the unmarked angle are congruent since it is an isosceles triangle, we subtract 40 from 180, with a result of 140. With 140, we divide by 2 to find the degrees for both the unmarked angle and angle a, since they are congruent. 140/2 = 70, Angle A will equal to 70 degrees

Nathan needs to sell at least 75 t shirts to get a bonus he already has sold 15 red tye dye shirts and 23 solid blue ones how ma
AnnyKZ [126]

Red shirts and blue shirts equally count to his bonus, so he has 15 + 23 = 38 shirts sold at this moment. He needs to sell 75 shirts for the bonus. We subtract our goal from what he have; 75 - 38 = 37.


The strategy here: subtract the goal (75 shirts) from what you did to get to the goal (15 shirts and 23 shirts).


Nathan needs to sell 37 more shirts for the bonus. Hope this helps.

Answer:

7.28 m

Explanation:

Use the Pythagorean Theorem. The length of the ladder is the hypotenuse.

a^2 + b^2 = c^2
a = 2, b = 7, c = ?

Plug in the values into the equation.

2^2 + 7^2 = c^2
4 + 49 = c^2

Square root both sides to get c = 7.28

Find the radius of a cylinder with a volume 686mm2 and a height of 14mm​
shtirl [24]

Answer:

r = 3.95 mm (nearest hundredth)

Step-by-step explanation:

\textsf{volume of a cylinder} = \pi r^2h

(where r = radius and h = height)

Given, volume = 686 mm² and height = 14 mm:

686=\pi r^2\times14

\implies\pi r^2=686 \div14=49

\implies r^2=49 \div \pi

\implies r=\sqrt{49 \div \pi }=3.949327085...

\implies r=3.95 \ \textsf{mm}
