1.) solve for x: 4x+9=25

2.) solve for x: 5x+12=62

Answers

Answer 1
1 4x+9=25 Answer: x=4
2: 5x+12=62 Answer: x=10
Answer 2

Answer:

1. x=4

2. x=10

Step-by-step explanation:

4x+9=25

Subtract 9 from both sides.

4x+9-9=25-9

>>4x=16

Then, divide 16 by 4.

x=16/4

>>x=4.

5x+12=62

Subtract 12 from both sides.

5x+12-12=62-12

>>5x=50

Divide 50 by 5.

x=50/5

x=10.

Hope this helps! Have a great day!

By what factor would your weight be multiplied if earth's diameter were 1/ 4 as big and earth's mass remained unchanged?.

Answers

Answer:

  16

Step-by-step explanation:

Your weight is (roughly) proportional to the inverse of the square of the distance you are from the center of the earth. If that distance is reduced to 1/4 its previous value, then your weight will be multiplied by the factor ...

  1/(1/4)² = 16

You would weigh 16 times as much.

What is a Jump Discontinuity?


brainliest is on the line and up for grabs

Answers

Answer:

Jump discontinuity is when the two-sided limit doesn't exist because the one-sided limits aren't equal. Asymptotic/infinite discontinuity is when the two-sided limit doesn't exist because it's unbounded.

Image result for What is a Jump Discontinuity?Jump Discontinuity is a classification of discontinuities in which the function jumps, or steps, from one point to another along the curve of the function, often splitting the curve into two separate sections. While continuous functions are often used within mathematics, not al functions are continuous

An electronics store had a special sale on two different models of calculators. The more high-tech model sold for $33.02 and
the older model sold for $18.55. All together, 28 calculators were sold. Total sales came out to $736.45. Which system of
equations can be used to determine how many high-tech models were sold, x, and how many older models were sold, y?

Answers

Answer:

$736.45/$33.02 = 22.30 high tech

x($33.02) = $736.45

$736.45/$18.55 = 39.70 older models

y($18.55) = $736.45

Two architects bid for a small government project, both
charging a flat fee added to an hourly rate. Amazing
Designs bids $250 plus $45 per hour, while Super Structures
bids $100 plus $60 per hour. At what point in time will the
two companies charge exactly the same amount?

Answers

Answer:

10 hours

Step-by-step explanation:

let x be the total number of hours

Amazing design total charge = 45x+250

super structures total charge = 60x+100

both companies charge the same amount when both equation equals

45x+250=60x+100

60x-45x=250-100

15x=150

x=10

therefore at 10 hours both companies will charge the same amount

If tax is 6.25%

Answer:

65.5 in

Step-by-step explanation:

Ok, the two triangles are similar, since they're both right triangles, the angle in C are congruent, and the third has to be by difference. It means that the distance DC is proportional to 44 inches, on the proportion[tex]x:44 = 11.5:23.5 \rightarrow x= 44\frac{11.5}{23.5} = 21,5 in[/tex] To this we need to add the 44 inches traveled in the first part, to get a total of 65.5 in

Answer:

A.

Step-by-step explanation:

The triangles are similar, so we can estimate that the ratio between them is 1:2 (23.5/11.5~~2). Now we have that 44/2 is 22 and 44+22 is 66. The closest answer to 66 is 65.5, which is A.

Molly drew a map of her town. She graphed the point L(−1.75, −3) for the library. The ice cream shop is located at L′, a reflection of L across the x-axis. The fire station is located at L′′, a reflection of L′ across the y-axis. Identify the ordered pair that describes the location of the fire station. Express your answer using decimal notation.

(__,__)

Answers

Answer:

(1.75, 3)

Step-by-step explanation:

Let's find L' first: We are reflecting L over the x axis, it means it stays on the same vertical (x=-1.75) and it's y changes sign, going to (-1,75,3).

This new point gets reflected again, over the y-axis. The horizontal coordinate (y=3) remains the same, and  the x coordinate changes sign, going to it's final destination (1,75, 3)

ANSWER:
(1.75, 3)

First, we have to flip (-1.75,-3) over the x-axis, which’ll leave us with (-1.75,3). Then we flip that point over the y-axis, which gives us (1.75, 3).
Just incase you have trouble doing reflections here’s the rules:

reflections over the x axis: (x,y)—>(x,-y)
reflections over the y-axis: (x,y)—>(-x,y)
reflections across y=x: (x,y)—>(y,x)
reflections across y=-x: (x,y)—>(-y,-x)

The Hiking Club plans to go camping in a State park where the probability of rain on
any given day is 0.57. What is the probability that it will rain on at least four of the
seven days they are there? Round your answer to the nearest thousandth.

Answers

Answer:

  0.650

Step-by-step explanation:

The probability of rain on 4 or more days is the sum of the probabilities of rain on 4, 5, 6, and 7 of the days.

The probability of rain on 4 days is ...

  7C4×(0.57)^4×(1 -0.57)^(7-4) ≈ 0.29375

On 5 days, it is ...

  7C5×(0.57^5)(0.43^2) ≈ 0.23363

On 6 days, it is ...

  7C6×(0.57^6)(0.43^1) ≈ 0.10323

And on all 7 days, it is ...

  0.57^7 ≈ 0.01955

The sum of these probabilities is ...

  P(≥4) = 0.29375 +0.23363 +0.10323 +0.01955 = 0.65016

The probability of rain on 4 or more days is about 0.650.

You can wash a car 1.5 times as fast as your friend. Working together, the two of you can wash 1 car in 6 minutes. How long does it take each of you to wash the car when working alone? Leave your answer as a fraction!

Answers

If the two of you can wash 1 car in 6 minutes:

It will take you 10 minutes to wash the car alone

take your friend 15 minutes to wash the car alone

Let the duration you can work be represented by y

Let the duration your friend can work be represented by x

You can wash a car 1.5 times as fast as your friend

That is, y = 1.5x

Working together, the two of you can wash 1 car in 6 minutes

This can be represented by the equation

[tex]\frac{1}{x}+\frac{1}{y} = \frac{1}{6}[/tex]

Substitute x = 1.5y into the equation above

[tex]\frac{1}{1.5y}+\frac{1}{y} = \frac{1}{6}\\\\\frac{1+1.5}{1.5y} = \frac{1}{6}\\\\\frac{2.5}{1.5y} = \frac{1}{6}\\\\1.5y=2.5(6)\\\\1.5y=15\\\\y=\frac{15}{1.5} \\\\y=10[/tex]

It will take you 10 minutes to wash the car alone

Substitute y = 10 into x = 1.5y

x  =  1.5(10)

x  =  15 minutes

It will take your friend 15 minutes to wash the car alone
