A)
2+(3+5)
B)
2(3+5)
C)
2 + 15
D)
6 + 5

Answer:

1.5 cm.

Step-by-step explanation:

If 1 cm = 30 km, then half a cm equals 15 km.

We need to find 45 km. We know that 1 cm = 30km and half a cm = 15 km. Adding both of these together, we can get 1.5cm = 45km.

Step-by-step explanation:

Answer:

10lbs because you would multiply 4.5 by 2.205 which would be 9.9208 which would round to ten

Step-by-step explanation:

Answer:

100 - 10 = 90 + 7 = 97%

89/100*97= $86.33

100 + 15 = 115 + 7 = 122%

50/100 X 122= $61

100 + 7

48/100 X 107 = 51.36

51.36 + 10= $61.36

100 + 15 = 115

700/100 X 115 = 805

805 - 700 = $105

Answer:

x = 8

Step-by-step explanation:

The complete question illustrates that the rectangle has sides ABCD and I've represented it as an attachment.

We have that:

AB = 3x

AD = 7x

The perimeter is calculated as:

Perimeter = 2 * (AB + AD)

Substitute values for AB, AD and Perimeter

160 = 2 * (3x + 7x)

160 = 2 * 10x

160 = 20x

Divide both sides by 20

8 = x

x = 8

Answer:

40

Step-by-step explanation:

30/12=2.5

20/2.5=8

8+8+12+12=40

Answer:

-x+10

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

We know that x/20=.4

To find x multiply both sides by 20

this means that

x=8

cot(x) = cos(x) / sin(x)

so

cos(x) / cot(x) = 1 / (1/sin(x)) = sin(x)

Then

sin²(x) + sin(x) cos(x) / cot(x) = sin²(x) + sin²(x) = 2 sin²(x)

Answer   V≈351.86

Step-by-step explanation: V=πr2h=π·42·7≈351.85838

The formula for the volume of a cylinder is V=Bh  or  V=πr2h .

The radius of the cylinder is 4 cm and the height is 7 cm.

Substitute 4 for r and 7 for h in the formula V=πr2h .

V= pie (4)² (7)

v= pie ( 14) (49)

Answer:

The expressions here are;

6 + 5w

3-16v

4v+ 1

7-v

Step-by-step explanation:

Here, out of the given set, we want to choose all options that are expression.

To do this, we should understand that expressions do not have the equality sign like equations

So expressions are those in the set in which we do not have an equality sign

The right answer is thus;

6 + 5w

3-16v

4v + 1

Answer is 66.6 reapeating or about 67 hours

I think the answer is, 56.

Answer:

Kiersten height is 6 feet

Length of her shadow is 9 feet

Length of the shadow of the tree is 84 feet

Therefore, the height of the tree is

[tex] \frac{6}{9} = \frac{x}{84} \\ x = \frac{6 \times 84}{9} \\ \boxed{x = 56}[/tex]

Answer:

1. 640   2. $39

Step-by-step explanation:

1. 50 percent = half of the number so $320 is the sale price we just multiply it by 2 = 320 x 2 = 640

2. first, we find 35% of 60 = 21 then we subract it by 60 = 60 - 21 = $39

150 memos for 3 typists

The number of memos three typists can type in one day is given by the equation A = 150 memos

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of memos three typists can type in one day be A

Now , the equation will be

The number of typists = 4

The total number of memos by 4 typists = 600 words in 3 days

So , the number of memos by one typist for 3 days = total number of memos by 4 typists / 4

Substituting the values in the equation , we get

The number of memos by one typist for 3 days = 600/4

The number of memos by one typist for 3 days = 150 memos

So ,

The number of memos by one typist for 1 day = number of memos by one typist for 3 days / 3

Substituting the values in the equation , we get

The number of memos by one typist for 1 day = 150/3

The number of memos by one typist for 1 day = 50 memos

So ,

Number of memos three typists can type in one day A = number of memos by one typist for 1 day x 3

Substituting the values in the equation , we get

Number of memos three typists can type in one day A = 50 x 3

Number of memos three typists can type in one day A = 150 memos

Therefore , the value of A is 150 memos

Hence , the number of memos is 150 memos

Answer:

[tex]y=2x[/tex]

Step-by-step explanation:

We want to write an equation in slope-intercept form that passes through the points (2, 4) and (3, 6).

So, we will first find the slope. Let (2, 4) be (x₁, y₁) an let (3, 6) be (x₂, y₂).

The slope formula is given by:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

So, by substitution, our slope is:

[tex]\displaystyle m=\frac{6-4}{3-2}=\frac{2}{1}=2[/tex]

Now, we can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

By substitution:

[tex]y-(4)=2(x-(2))[/tex]

Distribute:

[tex]y-4=2x-4[/tex]

Adding 4 to both sides yields:

[tex]y=2x[/tex]

And we have our equation.

In this case, the y-intercept is 0.
