What is the slope of the line through (3, 2) and (-3, 4)?​

Alright!

To start this problem, we need to come up with equations that represent both of the Hosts' services

Key equation:

y = mx + b

x = the # of hours

Host A:

An initial $45 means this will be our constant

$16.25 per hour means it needs the variable x

Host A equation: y = 16.25x + 45

Host B:

An initial $51 means this will be our constant

$13.50 per hourmeans it needs the varible x

Host B equation : y = 13.50x + 51

To find the approximate number of hours (x) when both hosts charge the same amout, we must set their equations equal to each other.

16.25x + 45 = 13.50x + 51

Now, Solve!

16.25x = 13.50x + 51 - 45

16.25x = 13.50x + 6

16.25x - 13.50x = 6

2..75x = 6

now divide to find x!

x = 6 ÷ 2.75

x = 2.18

but we must round to the nearest tenth, so your final answer is

x = 2.2 hours!

Hope I helped! Comment if you have any questions about my solution :)

Answer:

4 pints

Step-by-step explanation:

All we need to do is convert the amount of each fruit from quarts to pints and then add them up.

For Cherries:

She measured [tex]1\frac{2}{3}[/tex] quarts.

1 quart = 2 pints

=> [tex]1\frac{2}{3}[/tex] quarts = [tex]1 \frac{2}{3} * 2 = \frac{5}{3} * 2 = \frac{10}{3}[/tex] pints

For Peaches:

She measured [tex]\frac{1}{3}[/tex] quarts.

=> [tex]\frac{1}{3}[/tex] quarts = [tex]\frac{1}{3} * 2 = \frac{2}{3}[/tex] pints

Hence, the amount of fruits she measures altogether, in pints, is:

[tex]\frac{10}{3} + \frac{2}{3} = \frac{12}{3} = 4[/tex]

She measured 4 pints of fruit altogether.

Step-by-step explanation:

The required volume of the rectangular prism is unknown and cannot be determined based on the given information.

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

Here,
The volume of a rectangular prism is given by the formula:

Volume = length x width x height

In this case, we are given that the length and width of the rectangular prism are 4 units, but we don't have any information about the height. So, we cannot determine the volume of the rectangular prism without knowing its height.

Therefore, the volume of the rectangular prism is unknown and cannot be determined based on the given information.

StepThe answer is 36 14/125 feet

-by-step explanation:

Final answer:

The total vertical distance the ball has traveled when it hits the surface for the fifth time is 38 feet.

Explanation:

To find the total vertical distance the ball has traveled when it hits the surface for the fifth time, we need to analyze the sequence of bounces. Each bounce is 3/5 as high as the preceding one, meaning the height decreases by a factor of 3/5 each time.

If the starting height is 10 feet, the first bounce will reach a height of 10 * (3/5) = 6 feet. The second bounce will reach a height of 6 * (3/5) = 3.6 feet, and so on.

To find the total distance, we need to sum up the heights of all the bounces. This can be calculated using the formula for the sum of a geometric series:

Sum = a * (1 - r^n) / (1 - r), where a is the initial term, r is the common ratio, and n is the number of terms.

In this case, a = 10, r = 3/5, and n = 5. Plugging in the values into the formula, we get:

Sum = 10 * (1 - (3/5)^5) / (1 - 3/5) = 10 * (1 - 243/625) / (2/5) = 10 * (382/625) / (2/5) = 10 * (382/625) * (5/2) = 191 * 5 / 25 = 38 feet.

answer

1, 2, 3, 4 = 90 degrees

5 = 41 degrees

6 = 39 degrees

7, 9 = 51 degrees

8, 10 = 49 degrees

step-by-step explanation

since this is a kite, the lengths p and q (the diagonals of the kite) are perpendicular to each other, so angles 1, 2, 3, and 4 are all 90 degrees

to find angle 5, we know that the kite is symmetric across the horizontal diagonal, so angle 5 would be the same as 41 degrees

to find angle 6, we also look at symmetry, so angle 6 is the same of 39 degrees

to find angle 7, all three angles in a triangle, bottom left, must add up to 180. since we know angle 3 = 90 and angle 6 = 39, angle 7 = 180 - 90 - 39 = 51 degrees

because of symmetry, angle 9 would be equal to angle 7 = 51 degrees

to find angle 8, all three angles in a triangle, bottom right, must add up to 180. since we know angle 4 = 90 and angle 5 = 41, angle 8 = 180 - 90 - 41 = 49

because of symmetry, angle 10 would be equal to angle 8 = 49

Instead of multiplying by 1.4, Sue should have multiplied by 1.04. Bill can decrease 160 by 6% by multiplying 160 by 0.94

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

So, firstly, Sue wanted to increase 160 by 4%

Increased value = 160 + 4% of 160

Now, 4% of 160 is calculated as:

[tex]\dfrac{160}{100} \times 4 = 160 \times 0.04[/tex]

Thus, we get:

[tex]\text{Increased value} = 160 + 160 \times 0.04 = 160(1 + 0.04) = 160 \times 1.04[/tex]

Thus, instead of multiplying by 1.4, Sue should have multiplied by 1.04

Now, Bill wants to decrease 160 by 6%

Decreased value = 160 - 6% of 160

Now, 6% of 160 is calculated as:

[tex]\dfrac{160}{100} \times 6 = 160 \times 0.06[/tex]

Thus, we get:

[tex]\text{Decreased value} = 160 - 160 \times 0.06 = 160(1 - 0.06) = 160 \times 0.94[/tex]

Thus, Bill can decrease 160 by 6% by multiplying 160 by 0.94

Thus, instead of multiplying by 1.4, Sue should have multiplied by 1.04. Bill can decrease 160 by 6% by multiplying 160 by 0.94

https://brainly.com/question/11549320

The correct multiplier Sue should have used is 1.04 to increase 160 by 4%. To decrease 160 by 6%, Bill should use the multiplier 0.94.

a)She incorrectly multiplied 160 by 1.4. The correct multiplier should be 1.04.

To increase a number by a percentage, you first find the decimal equivalent of the percentage.
For 4%, it is 0.04.

Add this decimal to 1.
(1 + 0.04 = 1.04).

Now, multiply the original number (160) by 1.04.

Therefore, 160 x 1.04

= 166.4.

b) Bill wants to decrease 160 by 6%. To find the correct multiplier,

First, find the decimal equivalent of 6%, which is 0.06.

To decrease a number by this percentage, subtract the decimal from 1.

(1 - 0.06 = 0.94).

Now, multiply the original number (160) by 0.94.

Therefore, 160 x 0.94

= 150.4.

The length of the female dust mite, 0.42 millimeters, is written in scientific notation as 4.2 × 10[tex]10^{-1}[/tex]millimeters.

Explanation:

To write the measurement of a female dust mite, which is 0.42 millimeter long, in scientific notation, we first identify the most significant digit and the decimal point. In scientific notation, numbers are typically written in the form of a single digit from 1 to 9, followed by a decimal point and the remaining significant digits, and then multiplied by 10 raised to the appropriate exponent.

The number 0.42 can be written as 4.2 times 10 to the power of negative one (because the decimal point has been moved one place to the right to place it after the first non-zero digit, 4).

So, in scientific notation, the length of a female dust mite is 4.2 × [tex]10^{-1}[/tex] millimeters.

Answer:

x = 0

y = 4

Step-by-step explanation:

Given

12x - 5y = -20

y = x + 4

Substitute x + 4 for y in the first equation

12x - 5(x + 4) = -20

Expand the bracket

12x -5 X x - 5 x 4 = -20

12x - 5x - 20 = -20

7x - 20 = -20

Add 20 to both sides to eliminate -20 on the left side

7x - 20 + 20 = -20 + 20

7x = 0

Divide both sides by 7 to isolate x

7x/7 = 0/7

x = 0

Substitute 0 for x in either equation to get y

Using equation 2, we have

y = x + 4

= 0 + 4

= 4

x = 0

y = 4

Step-by-step explanation:

Cost of your guitar = $ 600

Let your friend's guitar's cost be = n

According to the question =

Your guitar costs $ 40 more than twice the cost of your friend's guitar which is n ,but your guitar's cost is $ 600.

So ,the linear equation for this will be =

= 2n+$40 = $600

= 2n = $600-$40

= 2n = $ 560

= n = $ 560/2

= n = $ 280

The cost of your friend's guitar is $280 by creating an equation based on the cost comparison to your own guitar, and then solving for the variable representing your friend's guitar's cost.

You paid $600 for a new guitar, which costs $40 more than twice the cost of your friend's guitar. To find the cost of your friend's guitar, let's denote the cost of your friend's guitar as x. According to the information given, your guitar's cost can be represented by the equation 2x + $40 = $600. Solving for x will give us the following steps:

Subtract $40 from both sides of the equation: 2x = $600 - $40.

This simplifies to 2x = $560.

Divide both sides by 2: x = $560 / 2.

Therefore, x equals $280.

The cost of your friend's guitar is $280.
