Hello! answer: 10
Step-by-step explanation:
8 × 8 = 64
6 × 6 = 36
64 + 36 = 100
√100 = 10
10 × 10 = 100 therefore x = 10 hope that helps!

Pls help I will give crown
Answer:
35 yards
Step-by-step explanation:
The formula for an area of a trapezium or trapezoid is h(a+b)/2. H is the height, and a and b are the the two opposite sides. With substitution, we get 5(6+8)2 = 70/2 = 35
Answer:
35 yd²
Step-by-step explanation:
First, you need to find the remaining side:
You need to find the bottom side of the triangle: 8-6=2 yd
Let's calculate the area of the triangle:
[tex]\frac{5*2}{2} =5[/tex] yd²
Let's calculate the area of the rectangle:
6*5 = 30 yd²
Total area: 30+5 = 35 yd²
What are the center and the radius of the circle whose equation is (x-5)^2+(y+3)^2=16
CENTER : ( 5, -3)
RADIUS : 4
Answer:
Center (5,-3)
radius : 4
Step-by-step explanation:
Radius: is the square root of 16. The square root of 16 = +/- 4. Minus 4 has absolutely no meaning for a question like this so the radius is 4. Rule take the square root of the counting number on the right.
The center is the value when x - 5 =0 and y + 3 = 0
x - 5 = 0
x = 5
y + 3 = 0
y = -3

Find the value of each missing variable. PLS!!!
Answers:
[tex]x = 5\sqrt{3}[/tex]
[tex]y = 10[/tex]
==================================================
Explanation:
This is a 30-60-90 triangle. The short leg 5 is opposite the smallest angle 30 degrees.
The long leg is sqrt(3) times that of the short leg, which explains why x = 5*sqrt(3).
The hypotenuse is twice as long compared the short leg, so y = 2*5 = 10.
You could use trig ratios and the unit circle as another way to find x and y.

Answer:
E) 25.5 units²
Step-by-step explanation:
The figure is not carefully drawn, so it is difficult to tell that it is a trapezoid. The "height" of it is BC, the diagonal of a rectangle that is 1 unit by 4 units. The Pythagorean theorem tells you that length is ...
BC = √(1² +4²) = √17
We notice that the "bases" of the trapezoid (CD and AB) are 1 and 2 times this length. The trapezoid area formula tells us the area is ...
A = 1/2(b1 +b2)h
A = 1/2((√17)(1 +2))(√17) = 3/2(17) = 25.5 . . . . square units
_____
Alternate solution
Pick's Theorem is a theorem that can help you find the area of a polygon when its vertices are all on grid points. It tells you the area is ...
A = i + b/2 -1
where i is the number of grid points interior to the figure, and b is the number of grid points on the boundary. Here, the boundary grid points are those that are labeled plus the one at (-2, 1). Counting the interior grid points gives a total of 24, so the area by Pick's theorem is ...
A = 24 + 5/2 -1 = 25.5 . . . square units
__
Additional comment
Once you're familiar with Pick's theorem (and/or any of a few other methods of computing area from coordinates), you see that the area of any polygon whose vertices are grid points will be an integer multiple of 1/2. The only such answer choice here is choice E.
why in math, whenever you do an explanation, for example, 2x - 20, the subtraction sign make the 20 a negative number?
Answer:
The negative sign is put before numbers to make them negative, or make their signs the opposite of what the are.
You have a 20.
+ 20
You don't need to put the + there if there is nothing before it, but that is a positive 20.
If you put a negative in front of it;
- (+ 20) = - 20
If you have a negative in front of parenthesis;
50 - (2x - 20)
50 - 2x + 20
70 - 2x

Answer:
x=√30
Step-by-step explanation:
Because the triangle is equilateral and is cut by the bisector, both triangles are 30-60-90 triangles. Therefore, to find side x, you multiply the short side by √3. This means that side x is √10*√3=√30 units.
Which triangle is a translation of the gray triangle
Answer:
Triangle DEF
Step-by-step explanation:
Hi there!
A translation of a shape occurs when all the coordinates of the original image is shifted up, down, left or right by an equal value.
Triangle ABC is a reflection of the grey triangle across the y-axis. We know this because the y-axis acts like a line of symmetry between the two shapes.
Triangle DEF appears as if it's been shifted. Therefore, triangle DEF is a translation of the grey triangle.
I hope this helps!
What is the equation of the line that is parallel to the line x = -2 and passes through the point (5.4)?
Lines parallel to each others only occur when two slopes of equations are same. The definition of parallel lines is:
[tex] \large \boxed{m_1 = m_2}[/tex]
We are given the equation of a line which is x = -2. For x = a, the equation forms a verical line and has an undefined slope. These below are basic that you may need to learn when learning about the line graph:
y = a —> horizontal line; slope is 0.x = a —> vertical line; slope is undefined.For y = a, any a-values would have same x-values. For example, if we are given y = 2 then any domains or x-values can have the range of 2.For x = a, any a-values would have same y-values or range.Back to the question. We want to find the equation of a line that is parallel to the line x = -2 and passes through (5,4) point. Recall the definition of parallel line that both slopes of equations must equal. Since x = a for any a-values would give an undefined slope. That means our parallel would be x = b.
Because the line passes through (5,4) - for any a-values from x = a would give out the set of all real numbers for range. Therefore the equation of a line is x = 5.
Answer
The equation of a line that is parallel to x = -2 and passes through (5,4) is x = 5.I hope this helps! If you have any doubts or questions, don't hestitate to ask in comment! Good luck on your assignment and have a great day!

The Malcolms are taking a trip. Midville is 214 miles
from their home. Walesburg is 3 times as far.
How far is Walesburg from their home?
Answer:
642 miles
Step-by-step explanation:
Distance of Midville from their home = 214 miles
Walesburg is 3 times as far.
How far is Walesburg from their home?
Distance of Walesburg from their home = 3 × Distance of Midville from their home
= 3 × 214 miles
= 642 miles
Distance of Walesburg from their home = 642 miles
Suppose that the dollar cost of producing x ratios is c(x)=800+40x-0.2x^2. Find the average cost per radio of producing the first 40 radios.
Answer:
24radios
Step-by-step explanation:
Given that the dollar cost of producing x ratios is c(x)=800+40x-0.2x^2. Find
Average cost is expressed as dC(x)/dx
dC(x)/dx = 40-0.4x
C'(x) = 40 - 0.4x
If x = 40
C'(40) = 40 - 0.4(40)
C'(40) = 40 - 16
C'(40) = 24
Hence the average cost per radio of producing the first 40 radios is 24radios

Whats the Angle for A,B, and C? Ive been stuck on this problem for a while. It would be great if you helped
Answer:
b=57° (vertically opposite angles)
Step-by-step explanation:
57°+a+b+c=360° (angles around a point)
57°+57°+a+c=360°
114°+a+c=360°
a+c=360°-114°=246°
a=c (vertically opposite angles)
therefore 2a=246°
a=123°
b=123°

Answer:
h = 9.6 ft
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
h² + 7.2² = 12² ( h is the height of the building )
h² + 51.84 = 144 ( subtract 51.84 from both sides )
h² = 92.16 ( take the square root of both sides )
h = [tex]\sqrt{92.16}[/tex] = 9.6 ft
in a class of 32 students
Answer:
1.48 m
Step-by-step explanation:
mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
Then the sum for the 14 boys is
[tex]\frac{sum}{14}[/tex] = 1.56 ( multiply both sides by 14 )
sum = 21.84 m
The sum for the class of 32 is
[tex]\frac{sum}{32}[/tex] = 1.515 ( multiply both sides by 32 )
sum = 48.48 m
Thus the sum for the 18 girls is
sum = 48.48 - 21.84 = 26.64 m
Then mean height of girls is
mean = [tex]\frac{26.64}{18}[/tex] = 1.48 m
