Fred was purchasing rice for his restaurant for the week. He usually makes 150 dishes a week with rice and each portion is 5 ounces. How many pounds of rice should Fred purchase for the week?

Answers

Answer: He bought 46.875 pounds of rice for the week.

Step-by-step explanation:

Total rice he bought = (Number of dishes made in a week) x (portion of rice in each dish)

GIven: Each portion has 5 ounces of rice.

i.e. each portion has [tex]\dfrac{5}{16}[/tex] pounds of rice.    [ 1 pound = 16 ounces]

Total rice he bought ( in pounds)=[tex]150\times\dfrac{5}{16}[/tex]

[tex]=46.875\text{ pounds}[/tex]

Hence, he bought 46.875 pounds of rice for the week.

An angle measures 148° more than the measure of its supplementary angle. What is the measure of each angle? AND DONT PLAGERISE!!!

Answers

Answer:

Step-by-step explanation:

Supplementary angles add up to 180°.

“θ is 148° more than its supplement”

Supplement of θ = 180°-θ

θ = (180°-θ) + 148°

2θ = 328°

θ = 164°

Supplement of θ = 180°-164° = 16°

Bob and Sue are meeting on a stairway. Bob is at the top and Sue is at the bottom. There are 9 steps
from bottom to top. Bob can skip a step each time since he is going down, Sue will not skip any steps. On
which step will they meet.

Answers

Answer:

Bob is at the top, so he starts at step 9.

Sue is at the bottom, so she is at the step 0 (this is the floor, before stepping on step 1)

Sue climbs from one step on one step.

Then she if she climbs n times, she will be at the step number:

S(n) = 0 + 1*n

And Bob goes down by 2 steps each time, then after he goes down n times, his position will be:

B(n) = 9 - 2*n

We want to see when they meet, then we need to solve:

S(n) = B(n)

1*n = 9 - 2*n

1*n + 2*n = 9

3*n = 9

n = 9/3 = 3

n = 3.

This means that they meet a the step:

S(3) = 3*1 = 3

B(3) = 9 - 2*3 = 9 - 6 = 3

They meet at the third steep.

Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.

Step 1:

Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.

Step 2:

Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.

Step 3:

Combine like terms: (18 + 24) squared = 30 squared.

Step 4:

Evaluate each side: 1764 not-equals 900.

Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?

The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem.
