Answer:

The total area of the back classroom wall is (20ft x 12ft) = 240ft²

The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².

Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.

Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

Answer:

37.5

Step-by-step explanation:

cosФ = \(\frac{A}{H}\)

cos(33°35') = \(\frac{m}{45}\)

m = 45 × cos(33°35')

m = 37.5 (1d.p.)

The area of a 2D form is the amount of space within its perimeter. The area of the composite figure is 249 cm².

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

The area of the composite figure can be written as,

Area = ABCG + DEFG =  (4×10.5) + (11.5×18) = 42+207 = 249cm²

Hence, the area of the composite figure is 249 cm².

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Answer:

40.5 inches

Step-by-step explanation:

I’m not sure if this is correct or not but my thinking is that you just add 26.9, 8.5, and 5.1 together since it says “How much more snow fell in the one day storm in 2006 than normal falls in February and March combined?” And combined basically means all together.

Answer: 13.3 more inches of snow fell in one day storm than normally falls in February and March combined.

February and March combined: 8.5+5.1 = 13.6

Since the question asked how much more, that means you subtract:

26.9 - 13.6 = 13.3

Ruth’s new floor cost $432.

The cost can be calculated as follows.

First, calculate the area of dining room. Use the formula of rectangle area (width x length)

Area = width x length

= 6 yd x 9 yd

= 54 sq yd

Second, calculate the total cost.

Cost = 54 sq yd x $ 8 per sq yd

= $ 432

Hence it cost $ 432 to install the new wood floor.

Answer:

$432

Step-by-step explanation:

1. Find the area of the dining room. The equation for finding the area is Length x Width = Area, so, 9x6=54 square yards.

2. Then, since each square yard is $8.00, multiply 54 and 8 to get $432.

Step-by-step explanation:

To determine the coordinates as Jon wants to place it 14 points away

√10^2+(a+4)^2 = 14

100+(a+4)^2 = 196

(a+4)^2 = 96

a+4 = ±√96

a+4 = ±4√6

a= -4±4√6

For the first one, do 24 x 3/4 which is 18. So, there are 18 8th graders on the soccer team if there are 24 team members.

Use the same method for the second one. 3/4 x 36 = 27. There are 27 8th graders on the soccer team if there are 36 team members.

I'm not sure about the third, so I'm not about to lead you on to something that might not even be correct. (I'm legit in sixth grade, and just started doing rsm, but I know how to do the other questions)

If there are 12 8th graders, just reverse the steps. 12 x 4/3 = 16. Check your work by doing 16 x 3/4 = 12, which is correct. So, there would be 16 students on the team if there are 12 8th graders.

The median is the best measure of center because there are outliers present.

In this graph, there are some values that occur more frequently than others, which means that the data is not evenly distributed. Additionally, there are some values that are much larger than the others, such as the three dots above 3 and the single dot above 9. These values are considered outliers because they are much larger than the other values in the data set. Outliers can significantly affect the mean, making it an unreliable measure of center. Therefore, the median is a better measure of center for this data set because it is not affected by outliers.

Answer:

x = -25/3

Step-by-step explanation:

\( \frac{ - 25}{3} \)

Step-by-step explanation:

step 1: cross multiply

\( \frac{10}{3} = \frac{x}{ - \frac{5}{2} } \)

\(10 \times (- \frac{5}{2} ) = x \times (3)\)

\( - 25 = 3x\)

step 2: flip the equation

\(3x = - 25\)

step 3: divide both sides by 3

\( \frac{3x}{3} = \frac{ - 25}{3} \)

\(x = \frac{ - 25}{3} \)
