Answer:

1/8 to the power of 3

Step-by-step explanation:

its 1/2 length x 1/2 width x 1/2 height

Answer:

80

Step-by-step explanation:

because i mutipled

60 hamburgers

240÷2=120

120 for both each

120÷2=60

so i think its 60 hamburgers

correct me if im wrong

Sorry about that, here's the answers.

1. expanded form

2. regroup

3.  place value

4. A, C, D. The strategy I used was place value and regrouping. I chose these by using place value to help me understand how to regroup and what each option would sum to.

5. D. Ten thousands place

Answer:

1. Expanded form

2. Regroup

3. Place value

4. A, C, D,

C is correct because a one is equal to 1.

1 x 4,200 = 4,200. Therefore 4,200 ones is equal to 4,200. D is correct because a ten is equal to 10. 10 x 420 = 4,200. Therefore, 420 tens is equal to 4,200. A is the same as the rest but with hundreds.

5. A

Step-by-step explanation:

1. Expanded form refers to when a number is separated by place values. Like 555,555 being turned into 500,000 + 50,000 + 5,000 + 500 + 50 + 5.

2. Regrouping is separating number by places values to do an equation like subtraction. For example, 5 tens - two ones.

3. Place values refers to a digit in a number like the 1 in 2,134 is in the hundreds place and the 5 in 5,677 is the thousands place.

4. My answer explains it.

5. A is correct as the 2 in 321,705 is 20,000 while the 2 in 32,571 is 2,000. 20,000 is 10 times larger than 2,000. So the answer is 10.

Answer:

70

Step-by-step explanation:

Your sister's job requires a lot of traveling. Last week, she drove a different distance each day: 135, 150, 86, 54, and 105 miles. Find the first quartile of the set of distances.

We rearrange the terms

54, 86, 105, 135, 150

First Quartile formula =

1/4 (n + 1)th term

Answer:

Step-by-step explanation:

10 times 10 times 60 = 6000

6000 - (1600 + 2000) = 2,400

Answer:

7200 [tex]in^3[/tex]

Step-by-step explanation:

volume of the bottom + volume of the middle part + volume of the top part (I'm sorry this is so vague T-T)

[tex](8*60*10)+(2*40*10)+(8*20*10)= 4800+800+1600=7200[/tex]

Answer:

B.

–80, –110

Step-by-step explanation:

-80 and -110

It is an arithmetic sequence. The difference = -30. It is the difference between each number in the sequence: 10-40=-30

-50-30=-80

-80-30 =-110

-80

First Identify the sequence being made here.

10-40 = -30

-20-10 = -30

-50-(-20) = -30

Therefor this pattern is decreasing by a rate of 30 so to continue this, just subtract 30 from -50.

-50-30 = -80

The next term is -80.

Hope I helped!

Answer:

10.5.

Step-by-step explanation:

By similar  triangles:

IJ / 21 = 8 /(8+8) = 1/2

IJ / 21 = 1/2

IJ = 1/2 * 21

= 10.5.

Answer:

$265.27

Step-by-step explanation:

Aaron invested $7,000 in an account paying an interest rate of 3 5/8 compounded continuously. Mia invested $7,000 in an account paying an interest rate of 3 3/4% compounded monthly. After 17 years , how much more money would Mia have in her account than aaron, to the nearest dollar?

Aaron:

A = Pe^rt

r = 3 5/8%

r = 3.625/100

r = 0.03625 rate per year

A = Pe^rt

A = 7,000(2.71828)^(0.03625)(17)

= 7,000(2.71828)^0.61625

= 7,000(1.8519693482716)

A = $12,963.79

Mia:

A = P(1 + r/n)^nt

r = 3 3/4%

r = 3.75/100

r = 0.0375 rate per year

A = P(1 + r/n)^nt

A = 7,000(1 + 0.0375/12)^(12)(17)

A = 7,000(1 + 0.003125)^(204)

A = 7,000(1.003125)^204

A = 7,000(1.8898660935607)

A = $13,229.06

Difference between Mia and Aaron account

Mia - Aaron = $13,229.06 - $12,963.79

= $265.27

Answer:

=42.3

Answer: The correct answer is B. 523.3...cm^3

Step-by-step explanation:

4/3*pi*r^3 is the formula

first, divide the diameter by 2 to get the radius, now, you will begin solving.

4/3*5^3*3.14

5*5*5=125

4/3*125*3.14

125*3.14=392.5

4/3*392.5

523.3...

Answer:

40 meters for area 1

12 meters for area 2 so combined it will be 52 meters

this one is hard

explanation is:

the length is 2m more than the width doubled and so the width is 6 so 6 times 2 is 12 + 2 (from the 2m longer) is 14 so then using the formula for rectangles (the shapes may be rectangles due to the lengths being different from the width) (length x 2) + (width x 2)= 40=28+12 and 6+12=18 now 18+ 40 combined gives us 52

Answer:

A4t = m - R²

A=m/4t-R²/4t or (m-R²)/4t or 1/4 +(m-R²)/t

Answer:

A = 20 degrees

Step-by-step explanation:

Both legs of the triangles are 2x and equal, so we know that the triangle is isoceles. That means both acute angles are equal as well.

In a triangle there are 180 degrees

180 - 140 = 40

40 remainding degrees/ 2 equal angles

A = 20 degrees

Answer:

angle a = 20

Step-by-step explanation:

So like the person above me said

180-140=40

40 divided by 2 is 20

Answer:

Distance between mall and library is 6.32 miles.

Step-by-step explanation:

Coordinates of the door to the library is at (2, 4) and door to the mall is at (8, 4).

Since, distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

Distance = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

By this formula,

Distance between (2, 4) and (8, 4) will be,

Distance = [tex]\sqrt{(8-2)^2+(2-4)^2}[/tex]

               = [tex]\sqrt{36+4}[/tex]

               =  [tex]\sqrt{40}[/tex]

               = 6.32 miles

Answer:

See answers below

Step-by-step explanation:

Standard equation of a line is expressed as y = mx+b

m is the slope

b is the y intercept

Given the coordinate points (-2, -4) and B(1, -7)

Slope m = y2-y1/x2-x1

m = -7-(-4)/1-(-2)

m = -7+4/1+2

m = -3/3

m = -1

Get the intercept

Substitute m = -1 and (1, -7) into y = mx+b

-7 = -1(1) + b

-7 = -1 + b

b = -7+1

b = -6

Get thw equation

y = mx+b

y = -x + (-6)

y = -x - 6

Q.3 The equation in point slope form is expressed as y - y0 = m(x-x0)

Given the point (3, 5)

x0 = 3

y0 = 5

Given the equation y = 2x+3

mx = 2x

m = 2

slope = 2

Substitute the slope and the point in the expression

y - 5 = 2(x -3)

y - 5 = 2x - 6

y - 2x = -6 + 5

y - 2x = -1

This gives the required equation

Q.4 The equation in point slope form is expressed as y - y0 = m(x-x0)

Given the point (5, 7)

x0 = 5

y0 = 7

Slope = 3

Substitute the slope and the point in the expression

y - 7 = 3(x -5)

y - 7 = 3x - 15

y - 3x = -15 + 7

y - 3x = -8

This give the required equation

30000+6/100

(3000000+6)/100=3000006/100=30000.06

Answer:

19.1

Step-by-step explanation:

Pythagorean theorem: a^2+b^2=c^2

4^2+7^2=c^2

16+49=c^2

C^2=65

c=hypotenuse =root 65

Perimeter =7+4+root65=19.1ft

Answer:

The whole = 48

The percentage = 78%

The part = 37.44

Step-by-step explanation:

The given parameters are;

The number of responses for the competition = 48 responses

The percentage that voted for the black T-shirt = 75%

The whole = The total number of responses for the competition = 48

The percentage = 78% = The part/(The whole) × 100

The part = The missing information

To find the part, we substitute the values of the whole, and the percentage into the given following equation

The part = The percent × The whole

∴ The part = 78% × 48 = 78/100 × 48 = 37.44

The part = 37.44.

Step-by-step explanation:

Answer:

1/9 = 3^-2

1/8 = 2^-3

9 = 3²

8 = 2³

Answer:

15 sq cm

Step-by-step explanation:

Let 3x = area of 1st rectangle

7x = area of 2nd rectangle

8x = area of 3rd rectangle

(3x + 7x + 8x)/3 = 18

3x + 7x + 8x = 54

18x = 54

x = 3

3x = 3(3) = 9 = area of 1st rectangle (smallest)

8x = 8(3) = 24 = area of 3rd rectangle (biggest)

24 - 9 = 15 sq cm
