Z/5 - 5= 3 1/4. Please help me find the solution

Ok so first we need to get the variable on a different side than the constants. We can add 5 to both sides and get Z/5 = 8 1/4. Just because it easier to deal with, i like to turn a mixed number into an improper fraction so 8 1/4 becomes 33/4.
now we have Z/5 = 33/4
then multiply each side by 5 to get z alone
so we get z = 165/4
also can be written as
z = 41 1/4

3) Calculate the area of the entire triangle below. Show your work *<br><br> 22<br> 31<br> 8

dalvyx [7]

Answer:

a = 1/2 (b) (h)

Step-by-step explanation:

Use Pythagorean theorem for sub triangle on the left: 8^2 + h^2 = 22^2

Use Pythagorean again for sub triangle on the right: x^2 + h^2= 31^2

Find your base: 8+x=b

Find entire area: a = 1/2 (b) (h)

In the figure below, p ||q. <br> find m 7 if m 8=116°

Serjik [45]

Answer:

m∠7 = 64°

Step-by-step explanation:

∠7 and ∠8 are supplementary meaning they add up to 180°.

m∠7 + m∠8 = 180°

m∠7 + 116° = 180°

m∠7 = 64°

Which solid has a greater volume

Triss [41]

Answer:

The volume of cylinder and the volume of a cone, have equal volume measurements. So, the answer is C).

Step-by-step explanation:

Cylinder:

-Use the formula for the volume of a cylinder. Use both the radius and height for the formula in order to solve and get the volume:

$V = \pi r^2 h$

$V = \pi 2^2 6$

-Solve:

$V = \pi 2^2 6$

$V = \pi \times 2^2 \times 6$

$V = \pi \times 4 \times 6$

$V = \pi \times 24$

$V = 24\pi \approx 75.39$

--------------------------------------------------------------------------------------------------------

Cone:

-Use the formula for the volume of a cone and the radius and height for the formula and solve the formula to get the volume:

$V = \frac{1}{3} \pi r^2h$

$V = \frac{1}{3} \pi 3^28$

-Solve:

$V = \frac{1}{3} \pi 3^28$

$V = \frac{1}{3} \times \pi \times 3^2 \times 8$

$V = \frac{1}{3} \times \pi \times 9 \times 8$

$V = \frac{1}{3} \times \pi \times 72$

$V = \frac{1}{3} \pi \times 72$

$V = 24\pi \approx 75.39$

-So, according to the volume of a cylinder and the volume of a cone, They both have the same volume.

Cylinder: $75.39$ $ft^3$

Cone: $75.39$ $ft^3$
