On average, a refrigerator door is opened 22 times each day. Len has two refrigerators in his house. Based on this average, about how many times in a 9−week period are the refrigerator doors opened?

Answer:

C. 20

Step-by-step explanation:

45 + 5x + 35 = 180

5x + 80 = 180

subtract 80 from both sides

5x = 100

divide by 5

x = 20

Answer:

c = 20

Step-by-step explanation:

angle 2 + (5x + 35) = 180( angles on a straight line sum to 180)

Hope this helps

Answer:

there is no picture? I dont see it smh

Answer:

38 degrees, see below :)

Step-by-step explanation:

Hello! :)

So, we can use the Base Angles theorem to say the angle with 62 degrees is equal to angle 1.

Now we know angle 1 = 62 degrees.

Next, we can use the exterior angles theorem to say that angle 3 is the sum of the remote interior angles of the triangle so:

angle 3 = 62 + angle 1

= 62 + 62

= 124

Now we know angle 3 = 124 degrees

We can find angle 4 by subtracting 18 degrees and angle 3 from 180 degrees because we know that they all have to add up to 180 so:

angle 4 = 180 - (18 + 124)

= 180 - 142

= 38 degrees.

Answer:

x³ + x²y - 2xy² - xy + y²

Step-by-step explanation:

Given

(x - y)(x² + 2xy - y)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x² + 2xy - y) - y(x² + 2xy - y) ← distribute both parenthesis

= x³ + 2x²y - xy - x²y - 2xy² + y² ← collect like terms

= x³ + x²y - 2xy² - xy + y²

Answer:

Answer:

[tex]9x + 4 - 3y^2[/tex]

Step-by-step explanation:

Given

[tex]5x+4x - 1+3 - 7y^2 +2+4y^2[/tex]

Required

Simplify

[tex]5x+4x - 1+3 - 7y^2 +2+4y^2[/tex]

Collect Like Terms

[tex]5x+4x - 1+3 +2+4y^2- 7y^2[/tex]

Simplify like terms

[tex]9x + 4 - 3y^2[/tex]

Hence,

[tex]5x+4x - 1+3 - 7y^2 +2+4y^2[/tex] [tex]= 9x + 4 - 3y^2[/tex]

Answer:

y = -3

Step-by-step explanation:

Given the expression 7-(3.1-0.1у)=3-0.2у

We are to find the value of y as shown

7-(3.1-0.1у)=3-0.2у

Open the parenthesis

7-3.1+0.1y= 3-0.2y

3.9+0.1y = 3-0.2y

Collect like terms

0.1y+0.2y= 3-3.9

0.3y = -0.9

y = -0.9/0.3

y = -3

Hence the value of y is -3

For g(x)=1/2-3 the answer would be g= -5/2x

I don't really get the g(x)=-4 part...

Step-by-step explanation:

Answer:

3 4/9 is the answer not 4 4/9 coz when u divide 9/40 at the top you'll get 3 so write that as the whole number then u wud get a reminder of 4 write that as the numerator finally write the denominator as 9

Answer:

The answer is 4 4/9 or 4.444444

Answer:

49+0.89c

Step-by-step explanation:

This should be the answer good luck :)

First difference,

[tex]\Delta_{1} = a_{2} - a_{1} = 3 - 1 = 2 = 1 + 1[/tex]

Second difference,

[tex]\Delta_{2} = a_{3} - a_{2} = 6 - 3 = 3 = 2 + 1[/tex]

Third difference,

[tex]\Delta_{3} = a_{4} - a_{3} = 10 - 6 = 4 = 3 + 1[/tex]

And so on.

Assuming the pattern holds on, we see that

i-th difference,

[tex]\Delta_{i} = a_{i + 1} - a_{i} = i + 1[/tex]

[tex]\implies a_{i + 1} = a_{i} + i + 1[/tex]

Then, nth term is,

[tex]\implies a_{n} = a_{n - 1} + n[/tex]

[tex]= a_{n - 2}+ (n + (n - 1))[/tex]

[tex]= a_{n - 3} + (n + (n - 1) +(n - 2))[/tex]

[tex]= a_{n - (n - 1)} + \sum \limits^{n - 2}_{k = 0}(n - k)[/tex]

[tex]= a_1 + \sum \limits^{n - 2}_{k = 0}n- \sum \limits^{n - 2}_{k = 0}k[/tex]

[tex]= a_1 +n(n -2 + 1 )- \frac{1}{2} (n - 2)(n - 1)[/tex]

[tex]= a_1 +n(n -1 )- \frac{1}{2} (n - 2)(n - 1)[/tex]

[tex]= a_1 +(n -1 )(n- \frac{1}{2} (n - 2))[/tex]

[tex]= a_1 + \frac{1}{2} (n -1 )(2n- n + 2)[/tex]

[tex]= a_1 + \frac{1}{2} (n -1 )(n + 2)[/tex]

[tex]\implies a_{n} = 1 + \frac{1}{2} (n -1 )(n + 2)[/tex]

Now, the 21st term in the sequence is,

[tex]\implies a_{21} = 1 + \frac{1}{2} (21 -1 )(21 + 2)[/tex]

[tex]= 1 + \frac{1}{2} \times 20 \times 23[/tex]

[tex]= 231[/tex]

Answer:

[tex]7.96 *10^8kg[/tex]

Step-by-step explanation:

Given

[tex]Eiffel = 9.16 * 10^6\ kg[/tex]

[tex]Golden\ Gate =8.05 * 10^8kg[/tex]

Required

Determine the difference in mass

This is calculated by subtracting the mass of Eiffel tower from the mass of Golden gate bridge

[tex]Difference = Golden\ Gate - Eiffel[/tex]

[tex]Difference = 8.05 * 10^8 - 9.16 * 10^6[/tex]

Express [tex]10^8[/tex] as [tex]10^6 * 10^2[/tex]

[tex]Difference = 8.05 * 10^2*10^6 - 9.16 * 10^6[/tex]

Express [tex]10^2[/tex] as [tex]100[/tex]

[tex]Difference = 8.05 * 100*10^6 - 9.16 * 10^6[/tex]

[tex]Difference = 805 *10^6 - 9.16 * 10^6[/tex]

Factorize:

[tex]Difference = (805- 9.16) * 10^6[/tex]

[tex]Difference = 795.84 * 10^6[/tex]

Factorize the decimal number

[tex]Difference = 7.9584 *10^2 * 10^6[/tex]

[tex]Difference = 7.9584 *10^8[/tex]

Approximate:

[tex]Difference = 7.96 *10^8[/tex]

Answer:

the amswer is c

Step-by-step explanation:

Answer:

34

Step-by-step explanation:

Answer:

A. Genevieve

B. Sierra

Step-by-step explanation:

Genevieve uses 5 balloons per animal, but Sierra uses 6. We can find this by subtracting 360 from 440 (which gets us 80). To find the unit rate, we divide 20 into 80 (the amount of balloons used when she made 20 animals), and we get 4. So, Sierra uses 4 balloons per animal.

Since Genevieve uses more balloons per animal and started with less balloons than Sierra (she started with 425, versus Sierra, who started with 440), Sierra will have made more animals by the end of the day.

I hope this helps!
