Answer:

X=60°

Y=50°

Step-by-step explanation:

Triangles must equal 180° when you add all angles together.

Triangle with angle X

50+70=120
180-120=60
X=60°

To find the value of Y takes a few more steps, but it isn't hard!

Angle Y is on a line, which equals 180° just like a triangle.

We know X=60°, but we don't know what the blank angle equals.

We use the same steps as we did when finding X

60+50=110
180-110=70
Blank angle=70°

We know that the blank angle=70° and that X=60°

Since the line equals 180, we add the two angles and then subtract from 180, just like before!

70+60=130
180-130=50
Y=50°

If sin 0 = 7/25, find csc 0

kipiarov [429]

Answer:

$csc(\theta)=\frac{25}{7}$

Step-by-step explanation:

We know that:

$sin(\theta)=\frac{7}{25}$

And we want to find:

$csc(\theta)$

Remember that there is a trigonometric identity that relates the $sin(\theta)$ function with the $csc(\theta)$ function

$csc(\theta)=\frac{1}{sin(\theta)}$

Then if $sin(\theta)=\frac{7}{25}$ this means that:

$csc(\theta)=\frac{1}{\frac{7}{25}}$

Finally:

$csc(\theta)=\frac{25}{7}$

A company rents water tanks shaped like cylinders. Each tank has a radius of 5 feet and a height of 3 feet. The cost is 3 per cu

vova2212 [387]

Answer: the cost of renting one water tank is 706.5

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

From the given information,

Radius = 5 feet

Height = 3 feet

Therefore,

Volume = 3.14 × 5² × 3 = 235.5 cubic feet.

If the cost is 3 per cubic foot, then the cost of renting one water tank is

235.5 × 3 = 706.5

Harry had $32. He spent all the money on buying 3 notebooks for $x each and 4 packs of index cards for $y each. If Harry had bou

sattari [20]

Answer:

a. The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 50 is (8, 2).

Step-by-step explanation:

The second equation needs to be ...

5x +5y = 50

because the wording "short of $18" means that the actual cost of that purchase would be $18 more than the $32 that Harry had. 18+32 = 50.

The only answer choice that shows this as the second equation is choice A.

In fact, the solution to the system of equations is (8, 2), as can be seen in the graph below.
