Answer:
c. 10 cm
Step-by-step explanation:
The parallel sides of trapizium are the bases so
base 1(B1) =9cm , base(B2)= 12cm
[tex]area(a) = 105 {cm}^{2} [/tex]
the perpendicular distance means the height so lets find the height
area of trapizium= B1 + B2 × h
2
[tex] {105cm}^{2}(the \: given \: area) = \frac{9cm(the \: given \: base) + 12cm(the \: given \: base)}{2} \times h[/tex]
[tex] {105cm}^{2} = \frac{21cm}{2} \times h[/tex]
now we crisscross
[tex] {105cm}^{2} \times 2 = 21cm \times h [/tex]
[tex] {210cm}^{2} = 21cm \times h[/tex]
[tex] \frac{ {210cm}^{2} }{21cm} = \frac{21cm \: }{21cm} \times h[/tex]
h = 10 cm

Kirima is building a wall for her snow fort. She first makes a firm base out of snow, and then piles uniformly sized blocks of snow in a brick-like pattern. She has a maximum height for this wall in mind, and she wants to figure out how many blocks can be stacked vertically in her wall while remaining below this maximum. So, she constructs the expression 0.4x + 0.6 to measure the height of her wall, where all constants represent measurements in meters. Which of the following statements are true? Select all that apply. 0.4 represents the height of the wall. 0.4 represents the height of the base. 0.4 represents the height of each block. 0.6 represents the height of the wall. 0.6 represents the height of the base. 0.6 represents the height of each block.
Answer:
The correct option is;
0.4 represents the height of each block
Step-by-step explanation:
The information given are;
Kirima first builds a firm base of a given height
Kirima is building her wall using uniformly sized bricks
the height of the wall she is building depends on the number of blocks stacked to form the wall
Therefore, variable that depends on other variable, which is the dependent variable, y, is the height of the wall
The independent, which determines the value of the dependent variable is the number of blocks added, x
The gradient of the equation is the height of each block = 0.4
The y-intercept is the starting value, which is the firm base of dimension, 0.6
Therefore, 0.4 represents the height of each block.

Answer:
The formula is 4x+3x+2x=180.
x= 20
a= 40
b= 80
c= 60
Step-by-step explanation:
The expression is the angle measurments equaled to 180 degrees because they all make up a straight line (180 degrees).
You then find the other angle measurments by identifying the verticle angles.
For example, 3x= 60 degrees. Therefore angle C= 60 because it is verticle to 3x
**EMERGENCY** What is the best way to determine the graph of a situation?
Answer:
you look at the slope and y intercept for example,
y=4x+10
the slope is 4 (increases 4/1 at a time)
and the intercept is 10 (the line hits the y axis at 10)
Step-by-step explanation:
I need help. I’m not understanding this question
the answer is letter c.
Answer:
D
Step-by-step explanation:
slope=(-2-7)/(3-0)=-9/3=-3
f(x)-7=-3(x-0)
f(x)=-3x+7
Take any two points .
I took (0,7) and (3,-2),then slope=(y2-y1)/(x2-x1)=(-2-7)/(3-0)=-9/3=-3
you can take any two points.
Let us take (-6,25) and (-3,16)
slope=(16-25)/(-3-(-6))=-9/(-3+6)=-9/3=-3
eq. of line is
y-y1=m(x-x1),here m=-3
y-25=-3(x-(-6))=-3(x+6)=-3x-18
y=-3x-18+25
y=-3x+7
Here y=f(x)

Consider this question:
-2x=x^2-6
1) Rewrite the question by completing the square. Your equation should look like (x+c)^2=d or (x-c)^2=d.
2) What are the solutions to the equation?
Answer:
see explanation
Step-by-step explanation:
(1)
Given
- 2x = x² - 6 ( subtract x² from both sides )
- x² - 2x = - 6 ( multiply through by - 1 )
x² + 2x = 6
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(1)x + 1 = 6 + 1
(x + 1)² = 7
(2)
Take the square root of both sides
x + 1 = ± [tex]\sqrt{7}[/tex] ( subtract 1 from both sides )
x = - 1 ± [tex]\sqrt{7}[/tex]
Solutions are x = - 1 - [tex]\sqrt{7}[/tex] , x = - 1 + [tex]\sqrt{7}[/tex]
Suppose x = 7 is a solution to the equation 4x - 2(x + a) = 8. Find the value of a that makes the equation true
Answer:
[tex]a=3[/tex]
Step-by-step explanation:
So we have the equation:
[tex]4x-2(x+a)=8[/tex]
And we want to find a such that x = 7 is a possible solution.
To do so, substitute 7 for x. Thus:
[tex]4(7)-2(7+a)=8[/tex]
Multiply the left and distribute the right:
[tex]28-14-2a=8[/tex]
Subtract:
[tex]14-2a=8[/tex]
Subtract 14 from both sides:
[tex]-2a=-6[/tex]
Divide by -2: "
[tex]a=3[/tex]
So, the value of a is 3.
And our equation would be:
[tex]4x-2(x+3)=8[/tex]
And we're done!

what is the answer h+6\5=2
Answer:
h = 4/5
Step-by-step explanation:
h + (6/5) = 2
h = 2 - (6/5)
h = (10/5) - (6/5)
h = (10-6)/5
h = 4/5
Check:
(4/5) + (6/5) = 2
10/5 = 2
The solution to the equation h + 6/5 = 2 is h = 4/5.
Given is an equation h + 6/5 = 2, we need to solve for h,
To solve the equation h + 6/5 = 2, we need to isolate the variable h on one side of the equation.
Let's begin by subtracting 6/5 from both sides of the equation to get rid of the term on the left side:
h + 6/5 - 6/5 = 2 - 6/5
Simplifying the equation:
h + (6/5 - 6/5) = 2 - 6/5
The term (6/5 - 6/5) is equal to 0, so we have:
h + 0 = 2 - 6/5
Simplifying further:
h = 2 - 6/5
To combine the fractions on the right side, we need a common denominator, which in this case is 5.
We can convert the whole number 2 into a fraction with a denominator of 5:
h = (2 x 5)/5 - 6/5
This becomes:
h = 10/5 - 6/5
Now we can subtract the fractions:
h = (10 - 6)/5
Simplifying:
h = 4/5
Therefore, the solution to the equation h + 6/5 = 2 is h = 4/5.

Round 7.21 to the nearest whole number.
Answer:
7.21 ≈ 7Step-by-step explanation:
If you are rounding to the whole number you are rounding to ones so you need to look at the tenth digit:
2<5 so 7 stays the same (rounding down)
7.21 ≈ 7
The nearest whole number for the given number is 7.
What is rounding off?To change a number into an approximation having fewer significant digits. For example :-
Round off 15.4 to 15, round off 15.51 to 15.5 or to 16, round off 0.499 to 0, and round off 970,000 to 1 million.
Given is a number 7.21,
We know that, if the digit is less than 5, round down and if the digit is 5 or more than 5, round up.
Since, numbers after the decimal is not greater than 5, therefore, it will not change and will remain 7.
Hence, the required whole number is 7.

A retailer sold a vacuum cleaner for 40% below its marked price. The sale price was 50% above the cost to the retailer. What is the ration of marked price to cost?
Answer:
10 : 9
Step-by-step explanation:
Given that a retailer sold a vacuum cleaner for 40% below its marked price.
Let the marked price = P
40% below = (100 - 40)P/100
Sale price = 60P/100
Sale price = 0.6P
The sale price was 50% above the cost to the retailer.
That is, cost price = (100 + 50)0.6P/100
Cost price = (150)0.6P/100
Cost price = 1.5 × 0.6P
Cost price = 0.9P
What is the ratio of marked price to cost?
The ratio will be = P/0.9P
Multiply both the numerator and denominator by 10
Ratio = 10 : 9

Which point is an x-intercept of the quadratic function f(x)=(x-8)(x+9)
Step-by-step explanation:
An x-intercept of a function occurs when f(x) = 0.
In f(x) = (x-8)(x+9), f(x) will be 0 if either (x-8) is 0 or (x+9) is 0.
Hence, f(x) = 0 when x = 8 or x = -9.
