The cost of having a window fixed is $100 plus $20 per hour of labor. Using h for the number of hours of labor, write an expression that represents the total cost.

Answer:

No, the poster would not fit in the frame

Step-by-step explanation:

A rectangle is a quadrilateral (has 4 sides and 4 angles) with two pair of opposite and equal sides.

A square is a quadrilateral in which all sides are equal.

Given that the rectangular frame has a width of 40 inches and a length of 30 inches. The area of the rectangular frame is:

Area of rectangular frame = length * breadth = 40 inches * 30 inches = 1200 in²

Since the square frame has the same area as the rectangular frame, hence:

Area of square frame = length * length

length² = 1200

length = √1200 = 34.64

Therefore the dimensions of the square frame is 34.64 inches by 34.64 inches.

Hence a poster with dimensions of 36 inches X 36 inches cannot fit in the square frame.

Answer:

(p,r) = (1/3, 2/9)

Step-by-step explanation:

Here, we want to solve a system of equations

We can rewrite the second equation by dividing through by 2

So we have;

4p + 3r = 2

and

5p - 3r = 1

Add both equations:

9p = 3

p = 3/9

p = 1/3

Recall ;

5p - 3r = 1

3r = 5p - 1

Substitute the value or p here

3r = 5(1/3)-1

3r = 5/3 - 1

3r = 2/3

r = 2/9

So we have the solution set as;

(p,r) = (1/3 , 2/9)

Answer:

27cm²

Step-by-step explanation:

it should be the area of rectangle..

Answer:

Step-by-step explanation:

27 sq cm

Answer:

27

Step-by-step explanation:

w = 6

x = 2

5w

= 5 x 6

= 30

w / x

= 6 / 2

= 3

5w - w / x

= 30 - 3

= 27

Answer:

189.6m

Step-by-step explanation:

Area of reactangle= side₁ ×side₂

Let the other side of the rectangle be x meters.

Area of rectangle= 75.2m²

0.8x= 75.2

x= 75.2 ÷0.8

x= 94

Perimeter of rectangle

= 2(side₁ +side₂)

= 2(0.8 +94)

= 189.6 m

Answer:

3rd one down is the answer

Answer:

Well let's count how many 65's there are, there are 3

So there needs to be 3 dots on the data plot on top of the section, 65.

Let's exclude some answers, D and B since they don't have 3 hovering over the 65(since there are three 65's).

Let's count how many 67's there are, there are 4.

We need to get rid of any answers that are more than 4 or less than 4 that are hovering over the section of 67. There are no answers to get rid of, let's move onto the next number, 68! There are four 68's. Let's also get rid of any answers that have more than 4 or less than 4 on the section above 68 since we're looking at that number. C is our answer!

Given:

In triangle HIJ, N is the centroid and [tex]HK=10[/tex].

To find:

The value of KI.

Solution:

In a triangle, the centroid of the triangle is the intersection of its medians.

Median of a triangle from a vertex divides the opposite side into two equal parts.

It is given that, N is the centroid. It means JK, HL and IM are the medians of the triangle HIJ.

Since JK is a median of the triangle HIJ, therefore it divides the opposite side IH into two equal parts.

[tex]KI=HK[/tex]

[tex]KI=10[/tex]

Therefore, the value of KI is 10 units.

Answer: 153.94

Step-by-step explanation: Formula for area of a circle: pi * r^2

First find the radius by dividing the diameter by 2: 14/2 = 7

Then plug the radius, 7, and pi, 3.14, into the formula:

(3.14) * (7^2) = 153.94 inches squared

Answer:

Volume of sphere = 44.57 cm³

Step-by-step explanation:

Given:

Diameter of sphere = 4.4 centimeter

Value of π = 3.14

Find:

Volume of sphere

Computation:

Radius of sphere = Diameter of sphere / 2

Radius of sphere = 4.4 / 2

Radius of sphere = 2.2 centimeter

Volume of sphere = [4/3][π][r³]

Volume of sphere = [4/3][3.14][2.2³]

Volume of sphere = [4/3][3.14][10.648]

Volume of sphere = [1.333][3.14][10.648]

Volume of sphere = 44.568

Volume of sphere = 44.57 cm³

Step-by-step explanation:

Answer:

If the terms on the left hand side of the equals are the same as the terms on the right hand side of the equals, there will be infinite solutions

Step-by-step explanation:

If the terms on the left hand side of the equals are the same as the terms on the right hand side of the equals, there will be infinite solutions

12x+24x +18 = 36x +24 -6

Combining like terms

36x+18 = 36x +18

Subtracting 36x from each side

18 = 18

This is always true so  it does not matter what x is, the left had side will equal the right hand side

Answer:

x = [tex]\frac{83}{36}[/tex]

Step-by-step explanation:

Given

x - 2 [tex]\frac{1}{4}[/tex] = [tex]\frac{1}{18}[/tex] ( change mixed number to improper fraction )

x - [tex]\frac{9}{4}[/tex] = [tex]\frac{1}{18}[/tex]

Multiply through by 36 ( the LCM of 4 and 18 ) to clear the fractions

36x - 81 = 2 ( add 81 to both sides )

36x = 83 ( divide both sides by 36 )

x = [tex]\frac{83}{36}[/tex]

Answer:

3.50

Step-by-step explanation:

Necklace has beads and a pendant

b +p

There are 6 necklaces at a cost pf 43.80

6(b+p) =43.80

The beads for one necklace cost 3.80 so replace b with 3.80

6(3.80+p) =43.80

Divide each side by 6

6(3.80+p)/6 =43.80/6

3.80 +p = 7.30

Subtract 3.80 from each side

3.80+p-3.80 = 7.30 -3.80

p =3.50

Answer:

A = 14 units^2

Step-by-step explanation:

The figure is a triangle

A = 1/2 bh where b is the base and h is the height

A = 1/2 ( 7)*4

A = 14 units^2

Answer:

Area of triangle is 14 square units.

Step-by-step explanation:

Area of figure is given by

Area of triangle = 1/2 × b × h

Substitute the values,

Area of triangle = 1/2 × 7 × 4

multiply

Area of triangle = 1/2 × 28

Divide , to get

Area of triangle is 14 square units.

Answer:

1 and 2 are equivalent

For 1 , use distributive property. Distribute 5 to a and 3. 5 x a = 5a, and 5 x 3 = 15. Therefore, 5a + 15. This is why 1 is equivalent to number 2.

Answer:

non-convex polygon

Step-by-step explanation:

Hi there! Given the equation below.

[tex] \large{r + \sqrt{x} = 9}[/tex]

First is to subtract both sides by r-term to isolate x-term.

[tex] \large{r + \sqrt{x} - r = 9 - r} \\ \large{ \sqrt{x} = 9 - r}[/tex]

Because the x-term is in square root form. We have to square both sides to get rid of the square root.

[tex] \large{( \sqrt{x})^{2} = {(9 - r)}^{2} } \\ \large{x = {(9 - r)}^{2} }[/tex]

Alternative Solution

[tex] \large{x = {r}^{2} - 18r + 81}[/tex]

[tex]x=\frac{-7±\sqrt{5 } }{2}[/tex]

Step-by-step explanation:

4x² + 28x + 49 = 5

4x² + 28x + 49 - 5 = 0

4x² + 28x + 44 = 0

4(x² + 7x + 11) = 0

4(x² + 7x + 11) ÷ 4 = 0 ÷ 4

x² + 7x + 11 = 0
