Simplify |−19+9|/3−|14−22|/9.

aliina [53]

Answer:

2¾

Step-by-step explanation:

$\\ \sf \frac{ | - 19 + 9| }{3} - \frac{ |14 - 22| }{9}$

$\\ \sf = \frac{ | - 10| }{3} - \frac{ | - 8| }{9}$

$\\ \sf = \frac{10}{3} - \frac{8}{9}$

$\\ \sf = \frac{30 - 8}{9}$

$\\ \sf = \frac{22}{8}$

$\\ \sf = \frac{11}{4}$

$\\ \sf = 2 \frac{3}{4}$

Does a=2.1 b=7.2 c=7.5 form a right triangle

Anna007 [38]

Answer:

Yes

Step-by-step explanation:

If the longest side squared is equal to the sum of the squares on the other 2 sides then they form a right triangle

longest side = 7.5

7.5² = 56.25

2.1² + 7.2² = 4.41 + 51.84 = 56.25

Thus the 3 values form a right triangle.

A recipe for apple sause calls for 1/3 cup of honey. The recipe makes 8 servings. How many cups of honey are needed to make 20 s

Komok [63]

To make exactly 20 servings, we need to know how much honey is used for exactly one serving.
Given that 1/3 cup of honey equates to 8 servings, divide 1/3 by 8 to get the amount of honey needed for 1 serving.
Then, to figure out how much honey is needed for 20 servings, simply multiply that result by 20.

Hope this helps!

Lauren spent 3/5 of her money on a refrigerator. The refrigerator cost $756. How much money did she have left?

Lelechka [254]

Fractions are the part/whole. We can set this up to be...

3/5 = 756
756 x5/3 = 1260.

if she had 1260 to begin with and spent 756, she would have 504.00 left.

Problem is attached, need to use sin and cosine formulas

Tatiana [17]

In triangle 1, the values are α = 65°, a = 42.02, and 45.66. And in triangle 2, the values are β = 55.74, γ = 84.26, and c = 10.84.

<h3>What is the law of sines?</h3>

For any triangle ABC, with side measures |BC| = a. |AC| = b. |AB| = c,

we have, by law of sines,

$\dfrac{\sin \alpha }{a} = \dfrac{\sin \beta }{b} = \dfrac{\sin \gamma}{c}$

1. β = 15°, γ = 100°, and b = 12, then the missing side and angle will be

The sum is 180° of a triangle. Then the value of α will be 65°.

$\dfrac{\sin 65^o}{a} = \dfrac{\sin 15^o}{12} = \dfrac{\sin 100^o}{c}$

Then the value of a will be

a = 42.02

Then the value of c will be

c = 45.66

2. α = 40°, a = 7, and b = 9, then the missing side and angle will be

(sin 40°)/7 = (sin β) / 9

sin β = 0.82644

β = 55.74

The sum is 180° of a triangle. Then the value of γ will be 84.26°.

Then the value of c will be

c = 10.84
