<NMP = 73

Step-by-step explanation:

First, the sum of angles in a quadrilateral is 360degrees.

All the angles are given, aside from <NMP (for this problem will be denoted as <M). One has to solve for <M.

given,

<N = 95,

<O = 90,

<P = 112

set up an equation

<N + <O + <P + <M = 360

95 + 90 + 112 + <M = 360

simplfy

297 + <m = 360

inverse operations

287 + <M = 360

-287            -287

<M = 73

How do i do solving systems using elimination

Answers

Answer:

The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.

Answers

Answer:

Yes!

Step-by-step explanation:

If you distribute 4 into 3x-y, you will get the same thing (12x-4y) meaning they are equivalent.

Answer:

Yes

Step-by-step explanation:

4(3x - y)           |        12x - 4y

12x- 4y            =       12x - 4y

hence they are equivalent

A pitcher contains 2 liters of lemonade. Each serving of lemonade is 1/8 of a liter. If 1.75 pitchers of lemonade are made, how many servings will this provide? Choose the answers from the drop-down menus that correctly complete the statement.

Answers

Miss bell decorates her gazebo with colored lights. The base of the gazebo is a circle with a diameter of 12 feet. Using the same length of lights she's going to decorate the side of her garden shed which has a square base. What is the maximum side length of the shed

Answers

Answer:

The maximum side length of the shed = 9.42 ft

Step-by-step explanation:

From the given information:

Miss bell decorates her gazebo with coloured lights who base is a circle with diameter 12 feet. The first find the circumference of the gazebo by using the circumference of a circle since the base takes such shape.

Circumference of a circle = πd

Circumference of a circle = π × 12

Circumference of a circle = 37.699

Then; the circumference of the circle equates to the length of the lights.

However, using the same length, the maximum side length of the  garden shed whose base took a square form can be determined by using the perimeter of a square as the square length, which is;

P = 4L

where;

L = length of sides

37.699 = 4L

L = 37.699/4

L = 9.42 ft

Thus, the maximum side length of the shed = 9.42 ft

The 14 students in the Spanish club need to raise $562.84 for their summer trip to Spain. They have already raised $238.32. If each student raises the same amount, how much more money must each student raise?

Answers

Step-by-step explanation:

you have to subtract 238.32 from 562.84 and then divide by 14 to get $23.18

$562.84 - $238.32 = $324.52
$324.52 / 14 = $23.18

Point E is on line segment DF. Given DE=2x, EF=2x-6, and DF=3x+5, determine the numerical length of EF.

Answers

Answer:

[tex]DF = 38[/tex]

Step-by-step explanation:

Given

[tex]DE = 2x[/tex]

[tex]EF = 2x - 6[/tex]

[tex]DF = 3x + 5[/tex]

Required

Determine EF

Since E lies on DF, then

[tex]DF = DE + EF[/tex]

Substitute values for DF, DE and EF

[tex]3x + 5 = 2x + 2x -6[/tex]

Collect Like Terms

[tex]3x -2x -2x = -6 -5[/tex]

[tex]-x = -11[/tex]

Solve for x

[tex]x = 11[/tex]

Recall that

[tex]DF = 3x + 5[/tex]

Substitute 11 for x

[tex]DF = 3 * 11 + 5[/tex]

[tex]DF = 38[/tex]

Two walls measure 22 feet by 9 feet and two walls measure 26 feet by 9 feet. The ceiling measures 22 by 26. The floor has the same dimensions as the ceiling. What is the total wall area that will be painted? If a gallon of paint covers 144 square feet, how many gallons will we need?

Answers

Answer:

The total wall area is 864 ft²

The number of gallons of paint needed for the total wall area is 6 gallons.

Step-by-step explanation:

Given;

dimension of first two side walls = 22 feet by 9 feet

dimension of second two side walls = 26 feet by 9 feet

dimension of the ceiling =  22 by 26

The total wall area is given by;

A = 2(22 x 9) + 2(26 x 9)

A = 864 ft²

144 ft² ---------------1 gallon of paint

864 ft² --------------?

= 864 ft² / 144 ft²

= 6 gallons

Therefore, the number of gallons of paint needed for the total wall area is 6 gallons.

Answers

Answer:

1,050

Step-by-step explanation:

Julie phone company charges her a monthly fee of $35

And also an additional $0.10 per minute

Her bill for the month of June is $140

Therefore the value of m can be calculated as follows

0.10m + 35= 140

0.10m= 140-35

0.10m = 105

m= 105/0.10

m= 1,050
