Answer:

135 cars; 205 SUVs

Step-by-step explanation:

Let c = number of cars sold.

Let s = number of SUVs sold.

s = c + 70

c + s = 340

Substitute s in the second equation with c + 70 and solve for c.

c + s = 340

c + c + 70 = 340

2c = 270

c = 135

s = c + 70

s = 135 + 70

s = 205

Answer: 135 cars; 205 SUVs

Answer: 256 miles

Step-by-step explanation:

if 1 1/4 inches = 80 miles, then 1/4 inch = 16 miles (there are five 1/4 in 1 1/4 inches, so 80/5 = 16)

there are sixteen 1/4 inches in 4 inches, and we know that each 1/4 inch is equal to 16 miles, so 16*16 = 256

Quadratic equations are equations that has a leading degree of 2

GIven the quadratic equation expressed as x^2 + 10x + 12 = 36

Rewrite

x^2 + 10x - 36 + 12 = 0

x^2 + 10x - 24 = 0

Factorize

x^2 + 12x -2x - 24 = 0
x(x+12) -2(x+12) = 0
x - 2 = 0 and x = -12

Answer:

The average strand of hair is 25.4μm

Step-by-step explanation:

Diameter of dime is 2.985×10² times of diameter of human hair.

The correct option is B.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given,

Diameter of dime = 17.91mm

Diameter of human hair = 6.0×10⁻²mm

Ratio of diameter of dime to diameter of human hair = 17.91/6.0×10⁻²

                                                                                        = 2.985×10²

Hence, 2.985×10² times of diameter of human hair is diameter of dime.

Answer: Its D

Step-by-step explanation:

Answer:

I wouldn't say this is entirely correct, but I think it's 45%.

Step-by-step explanation:

If you started with $90 and it was reduced 20%, than 25% MORE, the final percentage that was lowered would be the 20% and 25% added together.

The answer is 45%.

(Please do tell me if I got this wrong!!)

The original price reduced to 60%.

A percentage is a ratio or number that can be expressed as a fraction of 100. Additionally, it is denoted by the symbol "%."

On September 1, a dress was priced at $90. On October 1, the price was reduced by 20%.

That means,

the price is now = $90 - (90 x 20 /100) = $72

On November 1, the price was further reduced by 25% of the October 1 price.

The price is now = $72 - ( 72 x 25 / 100) = $54

To find the percentage of original price;

The percentage of original price

= 5400 / 90

= 60%

Therefore, the final price is 60% of the original price.

Step-by-step explanation:

Mean :

13 + 25 + 7 + 28 + 42 + 7 + 15 + 23 + 1 + 17.

= 178

178 ÷ 10

= 17.8

Median =

13, 25, 7, 28, (42, 7,) 15, 23, 1, 17

= 42 + 17

= 59 ÷ 2

= 29.5

Range :

42 - 1

= 41

Hope it helps :))

Answer:

Mean- 17.8 Median- 16 Mode- 17.8

Step-by-step explanation:

1. Put the numbers in ascending order.

1, 7, 7, 13, 15, 17, 23, 25, 28, 42

2. Look for the median. The median is the number located in the middle of a set of numbers. In this case, the median is going to be between 15 and 17 because they are both in the middle. This means that the median will be 16.

1, 7, 7, 13, 15, 17, 23, 25, 28, 42

3. Find the mode. The mode is the number you see the most in a set of numbers. In this case, there are two 7's so 7 is the mode of this set.

1, 7, 7, 13, 15, 17, 23, 25, 28, 42

4. Find the mean. The mean is the overall average of a set of numbers. To find the average, find the sum of all the numbers in the set and divide it by the number of integers there are. In this case, there are ten integers, so we'll find the sum (178) and divide it by 10 to get a mean of 17.8.

[tex]\frac{1+7+7+13+15+17+23+25+28+42}{10}[/tex] = 17.8

5. Find the range. The range is basically the difference between the lowest and highest values in a set of numbers. The lowest number is 1 and the highest is 42. So, we'll subtract the two to get a range of 41.

1, 7, 7, 13, 15, 17, 23, 25, 28, 42

42 - 1 = 41

Answer:

See below.

Step-by-step explanation:

The side of the square is k.

The area of the square is k².

The diameter of the circle is k.

For a circle, radius = diameter/2.

The radius of the circle is k/2.

Formula for area of circle: A = πr².

Here, the radius, r, is k/2.

The area of the circle is π(k/2)² = (πk²)/4

The shaded area is the difference between the area of the square and the area of the circle.

shaded area = k² - (πk²)/4

We are told that the shaded area = A

A = k² - (πk²)/4

Multiply both sides of the equation above by 4.

4A = 4k² - πk²

The correct classification for the angle JML is an acute angle.

What is an acute angle?

An acute angle has a measure, or it's smaller, than a right angle.

Therefore, the acute angle is the small angle which is less than 90°

let's find the measure of ∠JML

Hence,

∠JML = ∠JMK + ∠KML

∠KML = 180 - 132 = 48 degrees.

Therefore,

∠JML = 41 + 48 = 89 degrees.

Therefore, the correct classification for the angle JML is an acute angle.

Answer:

2,4

Step-by-step explanation:

This question is quite simple. First you need to find the factors of 8. Then you need to see which factors of positive 8 can add up to make -6. The factors are -4 and -2. Then expand. Now you have the equation x^2-4x-2x+8. Now group it.

(x^2-4x) +(-2x+8)

Then take out the X from the first group and the -2 from the second. We want the values in the brackets to be the same.

Now you have

x(x-4)-2(x-4)

Take the x and the -2x and make it a group. Now you have (x-4)(x-2)

Set x-4 equal to zero. x-4=0 Now solve it like a regular equation. Add four to both sides. Now you have x=4

Do the same thing with (x-2) and you get x=2

4 and 2 are your solutions

Answer:

x = 4 and x = 2

Step-by-step explanation:

The easiest way to find the roots is by converting the function into its factored form. This can be determined by asking the question:

What two numbers have a product 8 and a sum of -6?

These two values are -4 and -2.

-4 x -2 = 8

-4 + (-2) = -6

These two numbers are used in the factored form of the equation. You can prove the accuracy of the factored form by re-expanding it (multiply all the terms in the first parentheses by the terms in the second parentheses). The factored form looks like this:

(x - 4)(x - 2)

The roots are the values that make the expression equal 0. This can be done by setting each parentheses equal to 0 and solving for "x".

x - 4 = 0                              x - 2 = 0

x = 4                                    x = 2

Therefore, the roots of the function x² - 6x + 8 are x = 4 and x = 2.

Answer:

-9

Step-by-step explanation:

use an equation to solve this

consecutive means in succession, one after the other

since they're odd, both numbers have to be odd

let x be the first number

x+x+2=-20

+2 because if you only +1, one of the numbers would be even

2x+2=-20

-2. -2

2x=-22

x=-11

the smaller would be -9 since we are adding x and x+2 together
