Benjamin decides to treat himself to breakfast at his favorite restaurant. He orders chocolate milk that costs \$3.25$3.25dollar sign, 3, point, 25. Then, he wants to buy as many pancakes as he can, but he wants his bill to be at most \$30$30dollar sign, 30 before tax. The restaurant only sells pancakes in stacks of 444 pancakes for \$5.50$5.50dollar sign, 5, point, 50. Let SSS represent the number of stacks of pancakes that Benjamin buys.

Answers

Answer:

4 stacks of packages

4 * 4 = 16 pieces of pancake

Step-by-step explanation:

Maximum amount to spend ≤ $30

Milk chocolate = $3.25

Pancakes per stack = 5.50 (sold in stacks of 4)

Let number of stacks = s

In equality terms :

3.25 + 5.50s ≤ 30

5.50s ≤ 30 - 3.25

5.50s ≤ 26.75

s ≤ 26.75 / 5.50

s ≤ 4.86

Hence, 4 stacks of pancakes can be purchased

Answer:

3.25+5.50S<30

Step-by-step explanation:

Benjamin can afford at most 16 pancakes

Kent can paint a room in twice as fast as Luannda. Together they can paint the room in 5 hours. How long would it take Kent to paint the room alone? Write an equation to solve

Answers

Answer:

for kent it would be [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

The computation is shown below:

Let us assume Luannda be [tex]\frac{x}{1}[/tex]

And for kent be 2x

Together they take 5 hours

So

[tex]\frac{x}{1} + \frac{2x}{1} = 5\ hours\\\\3x = 5\\\\x = \frac{5}{3}[/tex]

So for kent it would be [tex]\frac{1}{5}[/tex]

In ΔHIJ, the measure of ∠J=90°, HI = 8 feet, and JH = 1.9 feet. Find the measure of ∠H to the nearest tenth of a degree.

Answers

Answer:

21.9°

Step-by-step explanation:

In ΔHIJ, the measure of ∠J=90°, HI = 8 feet, and JH = 1.9 feet. Find the measure of ∠H to the nearest tenth of a degree.

We solve this above question using the Sine rule

a/sin A = b/sin B

In ΔHIJ, the measure of ∠J=90°, HI = 8 feet, and JH = 1.9 feet.

Hence:

HI/∠J = JH/∠H

= 8/sin 90° = 1.9/sin ∠H

Cross Multiply

∠H = arc sin(sin 1.9 × 90/8)

∠H = 21.9°

The students in Mr. Lin's class are having a car wash to raise money for a trip. They need at least
$600 to go on the trip. They have already raised $61. They make $14 for every car they wash.
The students want to know how many cars they need to wash to go on the trip.

Let c be the number of
cars the students wash. Write an inequality that represents the situation.

Answers

Answer:

14c + 61 is greater than or equal to (put the greater than symbol with the line underneath there) 600

The inequality for raising the money will be written as 14c + 61 > 600.

What is inequality?

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than the relation between variables and the numbers.

Given that the students in Mr. Lin's class are having a car wash to raise money for a trip. They need at least $600 to go on the trip. They have already raised $61. They make $14 for every car they wash.

The inequality will be written as,

Neely has $1.73 in coins. He gives his friend 1 quarter and 3 nickels.
What is the value of the coins he has left?

Answers

Answer:

2.13

Step-by-step explanation:

1.73+.25=1.98

1.98+.15= 2.13

Answer:

1.33

Step-by-step explanation:

A quarter is worth 25 cents so subtract it from $1.73.

1.73 - .25 = 1.48

So then you subtract the 3 nickels which equal 15 cents.

1.73 - .15 = 1.33

So the value left is $1.33.
