Answer:
42
Step-by-step explanation:
According to the description given, the angles are complementary angles.
Their measurements will add up to 90°.
[tex]90 - 48 = 42[/tex]
X should be equal to 42.

What is a right angle?
A right angle is an angle formed by a perpendicular line on a straight line. The angle in a right angle is equal to 90 degrees.
From the given information, if a line comes out of the right-angled point and splits it into two halves;
where:
1st angle = x degrees2nd angle = 48 degreesThe value of the x is:
(x + 48)° = 90° (sum of angles in a right angle triangle)
x = 90° - 48°
x = 42°

Find the slope of the line which goes through the given points.
d
A(2,8) and B(2,6)
Answer:
Undefined
Step-by-step explanation:
A slope is found using the formula rise (change in y) over run (change in x). The change in x is 0, and the change in y is -2. The answer is -2/0, but dividing by 0 gives you undefined. Don't believe me? Look at the attached image.
Hope this helps!
Answer:
Undefined
Step-by-step explanation:
Use the formula:
[tex]m=\frac{y+2-y_1}{x_2-x_1}[/tex]
Plug in the numbers/coordinates accordingly:
[tex]m=\frac{6-8}{2-2}[/tex]
[tex]m=\frac{-2}{0}[/tex]
m = undefined
When x = 0, the slope is undefined.
Complete the equation of the line through (−10,3) (−8,−8). Use exact numbers. y=
Answer:
y = -11/2x - 52
Step-by-step explanation:
Now follow the equation for slope: m = change in y / change in x.
[tex]\frac{y2-y1}{x2-x1}[/tex]
[tex]\frac{-8-3}{-8--10}[/tex]
[tex]\frac{-11}{2}[/tex]
The slope is -11/2. m=-11/2
Use slope-intercept form:
y=mx+b
Plug in a point and the slope:
-8 = (-11/2)(-8) + b
-8 = 44 + b
b = -52
y = -11/2x - 52
Answer:
-11/2x-52

Answer:
Tuesday, 1: 30 pounds
Tuesday, 2: 40% of the apples
Tuesday, 3: x ( or any variable) + 8
Tuesday, 4: 9a-3b
Step-by-step explanation:
Since she weighs 38% of the normal weight, you multiply the decimal form to the original weight, which is 78. So .38 multiplied by 78 is 29.64, and rounding it to the nearest pound would make it go up to 30.
38%=.38
.38 x 78=29.64
29.64 rounded = 30
If 3/5 of the apples are ripe, that means that 2/5 are not. An easy way to turn this fraction into a percent is to make the number out of 100. Since 5 x 20 is 100, you multiple both the numerator and denominator by 20. 2 x 20 is 40, 5 x 20 is 100, hence 40/100. The numerator will be the percentage.
5/5-3/5 = 2/5
2/5 x 20/20 = 40/100
40/100 = 40%
The unknown score would become a variable, and since its increasing by 3 it is +8.
Since the perimeter is adding all sides, you'd add all of the equations. The 3a's times 3 would be 9a, and the -b would become -3b.
3a - b + 3a - b + 3a - b
9a - b - b - b
9a - 3b

The Jellybean company is building a new cylinder container with a height of 3.5 inches and a radius of
2 inches. It needs a diagonal divider to separate the two flavors it plans on packing per container. The
production of this divider is being outsourced for manufacturing. What should be the length of the
diagonal divider after removing ¼ of an inch from its top to accommodate for packaging decorative
paper?
Answer:
Length of diagonal paper is 5.15 inch.
Step-by-step explanation:
Please refer to the images attached.
As per the cylindrical image, we have radius given as 2 inches.
Height as 3.5 inches - 0.25 inches = 3.25 inches
If we look closely, we actually have a right angled triangle whose
Base = 2+2 = 4 inches
Height = 3.25 inches
And we have to find the hypotenuse of triangle:
According to pythagoras theorem:
[tex]Hypotenuse^{2} = Base^{2} + Height^{2}[/tex]
[tex]\text{ Diagonal}^{2} = 4^{2} + 3.25^{2}\\\Rightarrow 16 + 10.5625\\\Rightarrow 26.5625\\\Rightarrow \text{Diagonal = }5.15\ inch[/tex]
Hence, Length of diagonal paper required is 5.15 inch.

Joe has 56 possible different outfits.
What are combinations?A combination is a mathematical method in which the number of possible ways in which a set of given items can be chosen, such that the order in which it happens does not matter items.
The number of possible outfits can be chosen as shown below:Joe has 7 different choices for shirts.
Joe has 4 different choices for pants.
Joe has 2 different choices for shoes.
This means that number of combinations in which Joe can choose an outfit can be found by multiplying all the choices.
This can be done as shown below:
Number of choices for shirts * Number of choices for pants * Number of choices for shoes
= 7 * 4 * 2
= 56 combinations.

HAVE noice DAY ^_^Can someone help me with this please? In Belleville, the library is due south of the courthouse and due west of the community swimming pool. If the distance between the library and the courthouse is 9 miles and the distance between the courthouse and the city pool is 15 miles, how far is the library from the community pool?
Answer:
12 miles
Step-by-step explanation:
A right triangle is formed, where the distance between the library and the courthouse is one leg ( = 9 miles), the distance between the library and the swimming pool is the other leg (let's call it x), and the distance between the swimming pool and the courthouse is the hypotenuse ( = 15 miles).
From Pythagorean theorem:
15² = 9² + x²
225 - 81 = x²
x = √144
x = 12 miles

Gideon asked 50 students at his middle school which option they would like for lunch: pizza, sandwiches or burritos. Ten students said pizza, 4 said sandwiches and the remaining students answered burritos. What percent of students in the school would you predict would choose burritos based on this survey?
Answer:
72% of students chose burritos
Step-by-step explanation:
first you would add up the total of kids that said they liked the other two options, which was pizza and sandwiches: 10+4=14
then you would take that number and subtract it from the total of all students: 50-14=36
and then you would take that number and divide it by 50: 36/50=.72
turn that into a percent and you'd get 72%

Answer:
y = 90°
Step-by-step explanation:
y + x = 110° because the sum of two interior angles is equal to an interior angle
x + 70° = y ➡ y - x = 70°
y + x = 110°
y - x = 70° add two equations

Maria bought an SUV for 21,000 dollars. Nancy bought a sedan for 2/3 as much. How much less did Nancy spend on her sedan?
Answer:
7000
Step-by-step explanation:
21,000*(2/3)=14000
21,000-14,000=7000
Answer:
7,000 dollars
Step-by-step explanation:
21,000 divided by 3 is 7,000 = 1/3
So 2/3 = 7,000 x 2 = 14,000
To find how much less Nancy spent on her sedan you do 21,000 - 14,000 = 7,000
