Rom4ik [11]3 years ago
8 0

Answer:

x = 84 , y = 168

Step-by-step explanation:

Sin 60 =  \frac{opposite side}{hypotenuse}\\\\ \frac{\sqrt{3}}{2}= \frac{AB}{BC}\\\\ \frac{\sqrt{3}}{2} = \frac{84\sqrt{3}}{y}\\\\Cross\ multiply ,\\\\y*\sqrt{3} =2*84 \sqrt{3}\\\\y= \frac{2*84*\sqrt{3}}{\sqrt{3}}\\\\y=168

Cos\60 =  \frac{adjacent}{hypotenuse}\\\\ \frac{1}{2}= \frac{AC}{BC}\\\\ \frac{1}{2}= \frac{x}{168}\\\\ \frac{1}{2}*168=x\\\\x= 84

Answer:

y = 4.05

Step-by-step explanation:

If x is the number of years since 2007 then x = 17 (since 2024-2007=17)

let's substitute 17 for x in the equation

y = 0.10(17) + 2.35
y = 1.7 + 2.35
y = 4.05

Therefore by 2024, every quart of olive oil will cost 4.05.

Determine the length (to 1 decimal place) of the arc that subtends an angle of 2.8 radians at the centre of a circle with radius
victus00 [196]

Answer:

33.6 cm

Step-by-step explanation:

We can use the formula for arc length to solve this.

s=r\theta

Where

s is the arc length

r is the radius

\theta is the angle subtended by the arc (in radians)

<u />

<u>The problem gives us theta = 2.8 radians and radius of the circle as 12 cm. We plug these into the formula and figure out the arc length (to 1 decimal place):</u>

s=r\theta\\s=(12)(2.8)\\s=33.6

2nd answer choice is right.

juan needs to measure 6 cups of flour for a recipe.he only has a 1/4 cup measuring cup.how many times must he fill the measuring
Luba_88 [7]

Answer:

Juan would need to fill up the 1/4 measuring cup 24 times.

Step-by-step explanation:

So to measure one cup of flour with a 1/4 measuring cup, you would need to fill up the 1/4 measuring cup 4 times. Since we want 6 cups, you would need to fill up the 1/4 measuring cup 24 times. 6 times 4 = 24. Hope this helps!
