A group of students go to the store to buy school supplies. If they buy three
binders and four notebooks, the bill will be $4.85. If they buy three binders and
ten notebooks, the bill will be $8.75. What is the cost of each binder and
notebook?

Answers

Answer 1

Answer: Binder = 75c    notebook = 65c

Step-by-step explanation:

3b + 10n = 875

3b + 4n = 485

Subtracting gives:

6n = 390

390/6 = 65

n = 65

Substitute 65 into 3b + 4n = 485

3b + 260 = 485

3b = 485 - 260

3b = 260

b = 75

The base of a triangle prism shown is an isosceles triangle having a height of H cm, and an area of 36cm squared
The perimeter of the front rectanglular face of the prism is 54cm

state the value of h on the diagram ​

Answers

Answer:

the value of h on the diagram is 9cm

Step-by-step explanation:

area = 1/2 * base * height

a = 1/2*b*h

36=1/2*8*h

36=4h

since the 1/2 will multiply the 8

36=4h

multiply both sides by 4

h=9cm.

A major storm has winds speeds that are at least 110 miles per hour.Write and solve an inequality that describes how much greater these wind speeds are than the slowest hurricane

Answers

Answer:

x ≥ 36 miles per hour

Step-by-step explanation:

The speed of a major storm is at least 110 miles per hour while the speed of the slowest hurricane is at least 74 miles per hour.

Let x represent how much greater these wind speeds are than the slowest hurricane. Therefore:

x ≥ 110 miles per hour - 74 miles per hour

x ≥ 36 miles per hour

This means that the winds speed must be 36 miles per hour greater than the slowest hurricane.

Billy had 5 gallons of paint. Bob had 4 kilograms of paint. How do you make the paint amount equal?

Answers

Answer:

We can make the paint amount equal by making sure the parameters have the same unit

Step-by-step explanation:

Billy had 5 gallons of paint. Bob had 4 kilograms of paint. How do you make the paint amount equal?

To solve the above question, we have the conversion rate:

We can make the paint amount equal by making sure the parameters have the same unit

Hence:

1 gallon (gal) = 3.785411784 kilogram (kg).

Billy had 5 gallons of paint.

1 gallon (gal) = 3.785411784 kilogram (kg).

5 gallons of paint = x

Cross Multiply

x = 5 × 3.785411784 kg

18.92705892 kilograms of paint

Approximately 18.93 Kilograms of paint

Therefore, Billy had 18.93 kg of paint and Bob had 4 kg of paint

Step-by-step explanation:

We observe that the sequence has 17 as its first term and a common difference of 12-17 = -5. Then the general term is ...

  an = a1 +d(n -1)

  an = 17 -5(n -1)

This can be simplified to the desired form.

  an = 17 -5n +5

Chris works at a jewelry store, and he earns 4% commission on all sales that he makes. If Chris's jewelry sales total $1,370, how much will he earn in commission?

Answers

Answer:

[tex]\boxed {\boxed {\sf \$54.80}}[/tex]

Step-by-step explanation:

Chris earns the commission on the jewelery sales. To calculate what he earned, multiply the commission rate and his sales.

[tex]commission= commission \ rate * sales[/tex]

His rate is 4% and his sales are $1,370

[tex]commission= 4\% * \$1370[/tex]

Convert the percent to a decimal. Divide by 100 or move the decimal two spots to the left.

4/100= 0.04 4.0   -->   0.4   -->   0.04

[tex]commission= 0.04* $1370[/tex]

[tex]commission = \$ 54.8[/tex]

Chris's commission is $54.80
