How many degrees is angle x?

Answers

Answer and Step-by-step explanation:

All triangles add up to 180, so to solve for x, add everything up and equal it to 180.

180 = 61 + 41 + x

180 = 102 + x

78 = x

78 is equal to x.

#teamtrees #PAW (Plant And Water)

The measure of the value of x is 78 degrees.

What is the triangle?

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.

The sum of all the angles in a triangle is add up to 180 degrees.

The sum of angle 1 is 61, and angle 2 is 41 degrees.

The value of x is;

[tex]\rm \angle x+61+41=180\\\\\angle x+102=180\\\\\angle x=180-102\\\\\angle x=78[/tex]

Hence, the measure of the value of x is 78 degrees.

Mr. Powell rents a storage space that is 7 feet high, 5 feet long, and 4 feet wide.
How many containers, each one cubic foot in volume, can Mr. Powell fit into the storage space?

Answers

Answer:

To find how many 1 by 1 containers can fit in his storage space we must find the volume of the storage space in cubic feet. The formula for the volume of a rectangular prism aka the room is length x width x height. With this formula, all we need to do is plug in all the values given to the variables.

volume = length x width x height = 5 x 4 x 7 = 20 x 7 = 140

Final Answer: 140 one foot by one foot containers  can fit in Mr. Powell's storage space

Each gallon of paint covers $200$ square feet. I have to paint one side of a wall that is $12$ meters tall and $80$ meters long. If a foot is approximately $0.3048$ meters, then what is the smallest whole number of gallons I can buy and have enough paint to cover the whole wall?

Answers

5 gallons of paint would be the least amount of paint you would need

The smallest whole number of gallons require to paint the wall is 52 gallons.

Given that, 1 gallon of paint = 200 ft², 1 foot = 0.3048 meters and dimension of wall is 12 meter by 80 meter.

What is the area of a rectangle?

The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.

Converting the dimension to feet :

12/0.3084 = 39.370078 feet

80/0.3084 = 262.46719 feet

Hence, the area of the wall is

Area = Length × width

Area of wall = 262.46719 × 39.370078 = 10333.3537427408 ft²

Let number of gallons required = x

Since, 1 gallon = 200 ft²

x gallons = 10093.516 ft²

Cross multiply :

200x = 10093.516

x = 10333.35374274082/200

x = 51.6667687137041 gallons

x = 52 gallons

Hence, the smallest number of gallons required to paint the wall is 52 gallons of paint.

#5: Solve the
following
equation

(Show Work

Answers

Answer:

r = 46  

Step-by-step explanation:

To solve the equation, solve for r by isolating the variable. Whatever you do to one side, do to the other.  

1) First, simplify the right side by combining like terms. Subtract the coefficients of the terms with the same variables. Subtract 5r by 4r.

[tex]60 = 5r-4r + 14\\60 = r + 14[/tex]

2) Now, finally isolate r by subtracting both sides by 14.

[tex]60 = r + 14\\46 = r[/tex]

So, r = 46.

A teacher has two large containers filled with blue, red, and green beads, and claims the proportions of red beads are the same in each container. Each student shakes the first container, selects 50 beads, counts the number of red beads, and returns the beads to the container. The student repeats this process for the second container. One student’s samples contained 13 red beads from the first container and 16 red beads from the second container.

Based on the 95% confidence interval, (–0.24, 0.11), is the teacher’s claim justified?

The teacher’s claim is not justified because the two sample proportions are different.
The teacher’s claim is not justified because the interval contains both positive and negative values.
The teacher’s claim is justified because the interval contains 0, meaning there is no difference in the proportions of beads in each container.
The teacher’s claim might not be justified because the interval contains both positive and negative values. It is plausible that the proportion of red beads in each container is different.

Nancy has a rectangular garden with length, I, width, w, and a perimeter of 28 feet The length of the rectangle is 2 less than 3 times the width. Choose the system of equations that can be solved to find land w

Answers

Answer:Perimeter =2l +2w

28=2(3x-2) + 2x

Width =4feet

Length =10feet

Step-by-step explanation:

Perimeter of rectangular garden =2(l+b)

Let the width be represented as X

And the length which is 3x-2

Such that the equation to solve for length and width be

Perimeter =2l +2w

28=2(3x-2) + 2x--- system of equation

Solving

28=2(3x-2) +2x

28=6x-4+2x

28=8x-4

28+4=8x

32=8x

X=32/8

X=4

List four rational numbers between -1 and 0

Answers

Answer:

4 rational numbers between -1 and 0 are;

(-¼, -½, ¼, ⅜)

Step-by-step explanation:

Rational numbers between two numbers say x and y is given by;

(x + y)/2

Thus;

Rational number between -1 and 0 = (-1 + 0)/2 = -1/2

Rational number between 0 and -1/2 = (-½ + 0)/2 = - 1/4

Rational number between 1 and -1/2 = (-½ + 1)/2 = 1/4

Rational number between 1 and -1/4 = (-1/4 + 1)/2 = ⅜

Thus,4 rational numbers between -1 and 0 are;

(-¼, -½, ¼, ⅜)

PV + Interest  =  FV

FV - PV = Interest
