The restaurant owner can spend $550 for uniforms, Write an inequality to find the number of uniforms she can afford to buy.
Complete Question
A restaurant owner is ordering new chef uniforms. Each uniform has a jacket and pants. The jackets cost $37.99 each, plus a one-time fee of $70.00 to add the restaurant's logo. The pants cost $27.99 each.
The restaurant owner can spend $550 for uniforms. Write an inequality to find the number of uniforms she can afford to buy.
Answer:
65.98x + 70 ≤ 550
Step-by-step explanation:
The jackets cost $37.99 each
The pants cost $27.99 each.
One-time fee of $70.00
Therefore, an inequality to find the number of uniforms she can afford to buy can be written as:
$(37.99 + 27.99)x + 70 ≤ $550
65.98x + 70 ≤ 550

A diver descends at a rate of 12 feet per minute for 11 minutes. Write and solve an expression to show what the divers ending depth would be.
Answer:
132ft
Step-by-step explanation:
Given data
We are told that a diver descends at 12 ft per minutes
The time taken is 11 minutes
From
Speed= distance/time
distance= speed*time
Substitute
distance= 12*11
distance=132ft
Hence the ending distance is 132ft
A circular "No Parking" road sign has a diameter of 26 inches.
Which measurement is closest to the area of the sign in square inches?
81.64 in.²
163.28 in.²
530.66 in.²
2,122.64 in.²
Answer:
i think 81.64
Step-by-step explanation:
The area of the road sign in the circular shape of diameter 26 inches is closest to 530.66 in².
A road sign "No Parking" is given in a circular shape of diameter 26 inches. we need to find the area of the sign.
What is the area of a circle?The area of the circle is pie times the square of the radius of a given circle.
The area of the circle = [tex]\rm \pi r^{2}[/tex]
The diameter of the circle is 26 in so, the radius will be half of the diameter which will be 13 in.
Now, the area of the circle = [tex]\rm \pi r^{2}[/tex]
the area of the circle = 3.14 × 13 × 13
= 530.66 in²
Hence, the area of a circle of diameter 26 inches is equal to 530.66 in².

Coach thompson has made student teams for a kickball tournament from 77 boys and 99 girls what is the greatest number of teams coach thompson can make
Answer: 11
Step-by-step explanation:
For us to know the greatest number of teams coach thompson can make, we have to find the highest common factor for 77 and 99. This will be:
77 = 1, 7, 11 and 77
99 = 1, 3, 9, 11, 33 and 99.
Therefore, we can see that 11 is the highest common factor to both and this is the answer

Step-by-step explanation:
Order these ratios from least to greatest- 7:2, 12 to 4, 20/6, 21:14, 10:5
pls :,)
Answer:
21:14, 10:5, 12 to 4, 20/6, and 7:2
Step-by-step explanation:
first simplify all the ratios.
the first one is already simplified
12 to 4 = 3 to 1
20/6 = 10/3
21:14 = 3:2
10:5 = 2:1
Next find the least common factor the the three digits, 1, 2, and 3 and which is 6.
Multiply the simplified factors into the least common factor. So 7:2 will be multiplied by 6 so it will be 21:6
Do it with the rest of the factors and get
21:6, 18 to 6, 20/6, 9:6, and 12:6
Finally order them from least to greatest,
9:6, 12:6, 18 to 6, 20/6, and 21:6
or
21:14, 10:5, 12 to 4, 20/6, and 7:2

It is the end of the semester, and the clubs at school
are recording their profits. The Science Club started out
with $20 and has increased its balance by an average
of $10 per week. The Math Club has saved $5 per

al. Choose the equation below which represents the
balance the science club has. Let x represent the
number of weeks and y represent the balance of the
science club's account
y= 20 + 50x
y= 20 + 10x
y= 10 + 20x
y= 10 + 10x
y=50 + 5x
Y=5 + 10x
Answer:
y=20 + 10x

sales tax included.
Round your answer to the nearest cent, as necessary.
Answer:
The answer is $875.34
Step-by-step explanation:
I got this answer from first finding what 6.75% of 819.99
819.99 * 6,75% = 55.349325
Next I rounded it.
55.349325 = 55.35
Lastly, I added 819.99 plus 55.35
819.99 + 55.35 = 875.34
