Answer:

4/13

Step-by-step explanation:

We can first find the GCD or GCF of 28 and 91. 91 in its simplest form is 13*7. 28 in its simplest form is 2*2*7. The only common factor they have is 7, so 7 is the GCD. We can divide both by 7 to get [tex]\frac{4}{13}[/tex]

Answer: 3.5 hours

Step-by-step explanation:

From the question, we are informed that Ray's burns 326 calories every hour. We are further told that he ate a doughnut that had 320 calories, and a latte had 820 calories. The total calories will be:

= 320 + 820

= 1140 calories

The number of hours needed to burn the calories will be the total calories divided by the amount of calories burnt in an hour. This will be:

= 1140/326

= 3.5 hours

Answer:

-313 is the 64th term

Step-by-step explanation:

you take the second term an minus the first term with the second one {2-(-3)}

{=5} then you take two an minus five

it gives you -3 then you press minus five again it gives you negative eight then you press (equals to)until you reach the term you looking for

Answer:

5x + 4y = - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

4x - 5y = 20 ( subtract 4x from both sides )

- 5y = - 4x + 20 ( divide all terms by - 5 )

y = [tex]\frac{4}{5}[/tex] x - 4 ← in slope- intercept form

with slope m = [tex]\frac{4}{5}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{4}{5} }[/tex] = - [tex]\frac{5}{4}[/tex] , thus

y = - [tex]\frac{5}{4}[/tex] x + c ← is the partial equation

To find c substitute (- 4, 3) into the partial equation

3 = 5 + c ⇒ c = 3 - 5 = - 2

y = - [tex]\frac{5}{4}[/tex] x - 2 ← in slope- intercept form

Multiply through by 4

4y = - 5x - 8 ( add 5x to both sides )

5x + 4y = - 8 ← equation in standard form

Answer:

First, we need to figure out the total amount of students:

+ 10 students(ten students leave)

+ 15 students(15 students left)

10 + 15

= 25 students.

x = will represent the total amount of students in each group, so:-

5 groups per x students.

5x = 25(total students before alteration)

÷5    ÷5

x = 5, there are 5 students in each group.

Answer:

See below.

Step-by-step explanation:

Given numbers :-

⇒ 176, 231, 247, 256, 272, 299, 325, 343, 366, 375

⇒ Median = 272 + 299 / 2 = 285.5

⇒ Mean = 2890/10 = 289

(a) median if 375 becomes 265

⇒ 176, 231, 247, 256, 265, 272, 299, 325, 343, 366

⇒ New median = 265 + 272 / 2 = 268.5

⇒ Decreases by 17

(b) mean if 375 becomes 265

⇒ New mean = 2890 - 110 / 10 = 2780/10 = 278

⇒ Decreases by 11

I can't really give a step by step but just find the distance for the numerator and denominator and simplify

Answer:

The first one is 12.0, the second one is 12.9, and the third one is greater than or equal to I believe

Step-by-step explanation:

1. because it wants the average but the average is 12.9 so we use the median which is 12.0

2. because it is basically making it into a fraction so 12.9 is the total average

3. 2.4 is greater than or it can be equal to 1.5

2,094 cm^3

==========================================================

Explanation:

The diameter of 20 cm divides in half to the radius r = 10 cm.

The height is h = 20 cm.

V = volume of the cone

V = (1/3)*pi*r^2*h

V = (1/3)*pi*10^2*20

V = 2,094.3951023932 is approximate

I used my calculator's stored version of pi when computing the volume

That value then rounds to 2,094 cm^3 when rounding to the nearest whole number.

Write the equation of line in slope-intercept form. Line parallel to y = 0.5x + 3 that passes through the point (−9,12)

Answer:

y - 12 = 0.5(x + 9)

Step-by-step explanation:

We want to find the line parallel to y = 0.5x + 3 that passes through the point (−9,12).

To some this, we will use the equation;

y - y1 = m(x - x1)

Here, x1 = -9, y1 = 12, m = 0.5

Thus;

y - 12 = 0.5(x - (-9))

y - 12 = 0.5(x + 9)

Answer:

Chicago

Step-by-step explanation:

Compare the temperatures:

-4, -14, -11, -13

Numbers become smaller to the left on the number scale.
For instance, -10 is less than -5.

So, -13, -11, and -4 are all greater than -14.

And the lower the temperature, the colder it is.

Thus, Chicago is the coldest.

Answer:

[see below]

Step-by-step explanation:

"The product of 5 and a number x is 14" would be:

[tex]5x=14[/tex]

[tex]5x=14\\\\\frac{5x=14}{5}\\\\ \boxed{x=2 \frac{4}{5}}[/tex] or 2.8

Hope this helps.

Answer:

C = 5/9 (F - 32)

This is a temperature scale change comparison.

By this we understand, that ,

1°C = 5/9°F

Which is equal to, 5/9°F = 1°C

These two statements are satisfied by I. and II.

So, the correct answers are, I. and II.

Final Price = 18 - 7.2

Final Price = $10.80

Answer:

AB = 36

Step-by-step explanation:

Since E is the midpoint of AB, then

AE = EB , substitute values

4x + 6 = 10x - 12 ( subtract 10x from both sides )

- 6x + 6 = - 12 ( subtract 6 from both sides )

- 6x = - 18 ( divide both sides by - 6 )

x = 3

Thus

AB = AE + EB = 4x + 6 + 10x - 12 = 14x - 6 = 14(3) - 6 = 42 - 6 = 36

Answer:

See below.

Step-by-step explanation:

The only number this is true for is 1 . The square root and cube root of 1 is 1.

For all other perfect square/ perfect cube numbers they are different. For example square root of 64 is 8 and its cube root.

The amount of wrapping paper needed for the square pyramid gift box is: 96.72 in.².

Surface area of a square pyramid = area of the square base + area of the 4 triangular faces = s² + 4(1/2bh).

We are asked to find the amount of wrapping paper that would be needed to wrap the gift box, which is the surface area of the gift box that has a square pyramid shape.

Given the following dimensions of the gift box:

s = 5.2 in.

b = 5.2 in.

h = 6.7 in.

Plug in the values into s² + 4(1/2bh):

Surface area of a square pyramid = 5.2² + 4(1/2 × 5.2 × 6.7).

Surface area of a square pyramid = 96.72 in.²

Therefore, the amount of wrapping paper needed for the square pyramid gift box is: 96.72 in.².
