A company that makes​ hair-care products had 400 people try a new shampoo. Of the 400 people, 16 had a mild allergic reaction. What percent of the people had a mild allergic​ reaction?

Answers

Answer:

4% of people had a mild allergic reaction

Step-by-step explanation:

16 is 4% of 400

[tex]y = p\% \times x[/tex]

[tex]p\% = y \div x[/tex]

[tex]p\% = 16 \div 400[/tex]

[tex]p = 0.04[/tex]

Convert decimal to percentage

[tex]p\% = 0.04 \times 100 = 4\%[/tex]

My Answer:

I am pretty sure it would be around 4%

Answer:

Step-by-step explanation:

1)

y is 3 times more than x.

X=0 Y=0  3x0=0

X=1  Y=3

X=2 Y=6

X=3 Y=9

X=4 Y=12

Then just plot it as co-ordinates (x,y)

2)

Y is 1/4 of x. Divide by 4

X=0 Y=0

X=4 Y=1

X=8 Y=2

X=12 Y=3

X=16 Y=4

Then just plot it as co-ordinates (x,y)

Consider the system of equations.

y = 3x + 2
y = -2/3x − 4

Explain why these particular equations can be graphed immediately.

Answers

Answer:

because you have the y intercept to plot and the slope to go off of from there

same for the second one

The equations are in slope-intercept form making them easy to graph.

Slope-intercept form: y = mx + b
plot y-intercept first (0,b)
then go rise over run for the slope to find other points.

Wilbur was training for a race that was 6 1/4 miles long. He could only run 1 1/4 miles before needing to stop to take a break. How many times will Wilbur need to take a break during his run?

Please help

Answers

Answer:7 2/4

Step-by-step explanation:

Alright let’s go step by step for this:

1.) 6 1/4 - 1 1/4 = 5

2.) If he can run 1 1/4 miles before needing a break you would have to divide that number into the subtracted number from above

5 ÷ 1 1/4

3.) simplify the equation

5 ÷ 1.25

4.) Then divide

Jason's family drinks 1.95 gallons of milk each week. What is the best estimate of the number of gallons they will drink in half a year (26 weeks)?

Answers

Answer:

The answer is 52 gallons.

Answer: 51 gallons

To find the amount that Jason will drink in 26 weeks, you need to multiply it by 26.

1.95 x 26 = 50.7

If you’re trying to estimate it, it’s closer to 51 gallons. So the answer is 51.

A pair of jeans are originally $39.50 and are 15% off. The sales tax is 7%. After the discount and tax, how much will the total be ?

A) $6.34
B) $7.82
C) $30.81
D) $35.93

Answers

Answer:

d

Step-by-step explanation:

85% of 39.50 is 33.575, 7% of 33.575 is 2.35, add 33.575 and 2.35 and you get 35.925, round it and you get 35.93

The amount paid after deducting discount and adding tax is $35.93

How to solve amount paid after discount

Original price = $39.50Discount off = 15%

New price = 85% of $39.50

= 0.85 × 39.50

= $33.575

Tax = 7% × $33.575

= 0.07 × 33.575

= $2.35025

Total price paid = New price + Tax

= $33.575 + $2.35025

= 35.92525

Approximately,

$35.93

Is the area of a square with a side length 2 inches greater than or less than the area of a circle with radius of 1.2 inches?

Answers

The answer would be greater than. The radius is have of your diameter. Meaning you area would have to be more than 2 inches for the radius to be 1.2 inches.

The area of a square with a side length of 2 inches is less than the area of a circle with a radius of 1.2 inches.

What is Area?

The measurement that expresses the size of a region on a plane or curved surface is called an area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

Given:

The side of the square, a  = 2 inches,

The radius of the circle, r = 1.2 inches,

Calculate the area of the square by the following formula,

Area of square = side × side

Area of square = 2  × 2 = 4 sq. inches.

Now calculate the area of a circle,

Area of circle = π × r²

Area of circle =  π × (1.2)²

Area of circle = 4.52 sq. inches.

Therefore, the area of the square is less than the area of a circle.
