Help what’s the answer?

Answer:

You will select both x = 1 + 5sqrt(2) and x = 1 - 5sqrt(2)

Step-by-step explanation:

Firstly you have to take the square root of both sides to get rid of the exponent. (x - 1)^2 = 50 becomes x - 1 = +- sqrt(50)

Then you simplify the right. x - 1 = +- 5sqrt(2)

The answer is both the positive and negative versions.

distance around a circle- like middle of an apple

Answer:

The circumference is defined as the distance around something round or rounded, especially the distance around the edge of a circle. An example of circumference is the distance around the outer boundary of a circle. The line bounding a circle, a rounded surface, or an area suggesting a circle.

Answer:

Each ride costs $1.25

Step-by-step explanation:

$20 - $13.75 = $6.25

$6.25 / 5 = $1.25

Answer:

1.25 per ride

Step-by-step explanation:

Subtract 13.75 from 20. You get 6.25. Divide 6.25 by 5.

Answer:

I'm pretty sure it's 144

Step-by-step explanation:

1.           160 divided by 5 is 32 so 1 quart = 32 pounds

2.          32 times 4.5 = 144

Answer:

c

Step-by-step explanation:

Given:

[tex]R^2=0.92,a=8000,b=0.9[/tex].

Exponential regression model is

[tex]y_1\sim a(b)^{x_1}[/tex]

To find:

The exponential regression representing the population of Lazy Town as a function of time in years.

Solution:

Exponential regression model is

[tex]y_1\sim a(b)^{x_1}[/tex]       ...(i)

We have, [tex]a=8000,b=0.9[/tex].

Substituting [tex]a=8000[/tex] and [tex]b=0.9[/tex] in (i), we get.

[tex]y_1\sim 8000(0.9)^{x_1}[/tex]

Therefore, the exponential regression representing the population of Lazy Town as a function of time in years, is [tex]y_1\sim 8000(0.9)^{x_1}[/tex].

29-18=11

c=11

18+2(11)=40

Answer:

30

Step-by-step explanation:

If A+B is 18, A and B should equal 9.

A+B+C=29, that should mean C=6.

A+B+2C=9+9+2(6)

9+9+2(6)=30

Answer:

A. £147.10

B. 17 children

Step-by-step explanation:

Let

Number of children = x

Cost of hiring a bouncy castle = £4.70 * x + £86

What is the cost of the bouncy castle for 13 children

Cost of hiring a bouncy castle = £4.70 * 13 + £86

= £61.1 + £86

= £147.10

How many children went to the party when cost of hiring bouncy castle = £165.90

Cost of hiring a bouncy castle = £4.70 * x + £86

£165.90 = £4.70 * x + £86

165.90 = 4.70x + 86

165.90 - 86 = 4.70x

79.9 = 4.70x

x = 79.9/4.70

= 17

x = 17 children

Answer:

The population of last year was 60.

Step-by-step explanation:

From the information given, as you know that the number of fish in a lake decreased by 25% between last year and this year, the amount of fish this year represents 75% of last year's population as: 100%-25%=75%. With that, you can use a rule of three to find last year's population tha would represent 100% given that 75% is equal to 45 fish.

75%   →  45

100%  →   x

x=(100*45)/75= 60

According to this, the answer is that the population of last year was 60.

Answer: Yes. They'll both make 4 apple pies.

Step-by-step explanation:

Jennifer makes 13 apple pies using 338 apples. The fraction of apple pies made based on the number of apples will be:

= 13 / 338

= 0.03485

Mateo used 9 apple pies using 216 apples. The fraction of apple pies made based on the number of apples will be:

= 9 / 216

= 0.0417

When they each have 105 apples, the number of apple pies that Mateo will make will be:

= 0.03485 × 105

= 3.65925

= 4 apple pie approximately

Jennifer will make:

= 0.0417 × 105

= 4.3785

= 4 apple pie approximately

Answer:

For this scenario, I used the elimination method. Organize the equations, so it's easier to subtract from each other. My x-variable will represent the number of hot dogs and my y-variable will represent the number of sodas.

3x+2y=213

x  + y =87

We need to make sure one of the monomials are alike in each equation, so we can eliminate a variable. Distribute 3 to each number/variable in the second equation.

3x+2y=213

3(x+y=87) --> 3x+3y=261

Now we can eliminate x.

  3x+2y=213

-  3x+3y=261

----------------------

        -y=-48  

Divide -1 to both sides to get y=48. So, you sold 48 cans of soda. Now, we can find the number of hot dogs by substituting 48 into the second equation to get x+48=87. Subtract 48 to both sides to result with x=39. So, you sold 39 hot dogs.
