can someone help me find the area please?
Answer:
100 in ^2
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 ( b1+ b2) *h where b1 and b2 are the lengths of the bases and h is the height
A = 1/2 ( 16+9) * 8
= 1/2 ( 25) *8
= 100 in ^2

Answer:
1. The radius is 90 ft.
2. 31.4 cm.
Step-by-step explanation:
1. The way to find the radius with just the diameter, is to divide by two.
2. When finding circumference, you need to multiply the diameter by 3.14 (pi), making it 10 x 3.14.
Answer:
The radius is 90
Step-by-step explanation:
the line in the middle of the circle is the diameter so in order to find the radius you need to find half of the diameter. Half of the diameter (180) is 90 90 the radius is 90.

Solve each equation for the indicated variable. u = -3a - 3 , for a
Answer:
[tex]a = \frac{u + 3}{-3}[/tex]
Step-by-step explanation:
Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, add 3 to both sides of the equation:
u = -3a - 3
u (+3) = -3a - 3 (+3)
u + 3 = -3a
Next, divide -3 from both sides of the equation:
(u + 3)/-3 = (-3a)/-3
a = (u + 3)/-3
[tex]a = \frac{u + 3}{-3}[/tex] is your answer.

Answer:
42
Step-by-step explanation:
On the bottom 7 was multiplied by 3 so you would do the same to 14.

5. Check for reasonableness
To answer this question, let us take an example of converting from inches to centimeters.
Let us convert 10 inches to centimeters.
First step is to identify the measure to be converted which in this case it is inches that is the measure.
Second step is to write the conversion factors which is;
1 inch = 2.54 cm
Third step is to cancel the units; In this case the units to be canceled will be inches.
Fourth step is to multiply the original measurement by the conversion factor to give; 10 × 2.54 cm = 25.4 cm
Fifth step is to check for reasonableness by trying to check if using another number will give a reasonable answer.

the question is 7a + 10 = 2a
Answer:
a = -2
Step-by-step explanation:
Subtract 10 from both sides:
7a + 10 - 10 = 2a - 10
Simplify:
7a = 2a - 10
Subtract 2a from both sides:
7a - 2a = 2a - 10 - 2a
Simplify:
5a = -10
Divide both sides by 5 and simplify:
a = -2
Answer:
A = -2
Step-by-step explanation:
Subtract 10 from both sides:
7a + 10 = 2a -10
Simplify the expression, 7a = 2a - 10
Subtract 2a from both sides next
7a - 2a = 2a - 10 - 2a
Subtract 7a - 2a
5a = -10
5a / 5 = -10/5
a = -2

Step-by-step explanation:
a squared + b squared = c squared, where as 6 is a, 3 is b, and x is c.
6 squared + 3 squared is 36+9=45, so x is the square root of 45.

Answer:
X-Intercept (s) (207/5, 0)
Y-Intercept (s) (0, 207/8
Step-by-step explanation:
To find the x-intercept, substitute in 0 for y and solve for x . To find the y-intercept, substitute in 0 for x and solve for y .
George’s age is three times that of his brother. When you add George’s age to his brother’s, you get 24. How old is each brother?
a) Write an equation that represents the situation. Explain any variable used.
b) Solve the equation from Part (a). Show your work. State your solution as a complete sentence.
Answer:
G=18
Step-by-step explanation:
George-G
1/3G+G=24
4/3G=24
3/4*4/3G=24*3/4
G=18
George will be 18 years old there we can find his brothers age by dividing it by three thus 18/3=6
Answer:
George is 18 and his brother is 6
Step-by-step explanation:
let the brother's age be n then George's age is 3n ( 3 times his brother's age )
n + 3n = 24 ( sum of their ages )
4n = 24 ( divide both sides by 4 )
n = 6
and 3n = 3 × 6 = 18
George is 18 years old and his brother is 6 years old.
Through (1,-4) Slope = -8
A. Rewrite the equation of the line in slope intercept form
B. Identify the slope and y intercept
(Show steps )
Answer:
Rewriting the equation in slope intercept form is: Y= -8x+4
Step-by-step explanation:
Im sure there's a faster way to solving this, but I'm just in 8th grade so I'm gonna apply what I know so far.
First of all, we know that our slope is -8... so we have y= -8x so far
From here, to find out y intercept I knew that our slope deals with all the points assigned, therefore we know that from -4 the change would be -8 so we get -12. We can also go the other way. This means that we plus 8 to get positive 4. (Side note: the change in our x value is 1 so we know that our y intercept is always dealing with a 0 in the x position) ex. (0,9) the y intercept would be 9.
To wrap things up, the slope is -8 and the y intercept is 4.
We then get Y= -8x+4
Hope this helps! :)

Subtract 18 from each side
-18 = -6x
Divide by -6
-18/-6 = -6x/-6

Answer: x=64°
Step-by-step explanation:
According to the diagram, the two intersecting lines are perpendicular. That means each part is 90°. Since the left side is labelled to be 180°, we know that the sum of the right side is also 180°.
26+x+90=180 [combine like terms]
116+x=180 [subtract both sides by 116]
x=64°
Now, we know that x=64°.
On the other hand, we can see that 26+x=90. We can also use that to solve for x.
26+x=90 [subtract both sides by 26]
x=64°

-3/5 x = 6 how do I solve for x
Divide the sides of the equation by -3/5 :
-3/5 ÷ -3/5 x = 6 ÷ -3/5
1 x = 6 × -5/3
x = -30/3
x = -10
and we're done.

A =72 in^2
When dilated
=1152 in ^2
Step-by-step explanation:
The area of the triangle is
A = 1/2 bh
We need to convert the units to match
2 ft= 24 inches
A = 1/2 ( 24*6)
A = 1/2 (144)
A =72 in^2
When dilated 6 inches *4 = 24 inches
24 inches *4 = 96 inches
A = 1/2 ( 96*24)
= 1/2(2304)
=1152 in ^2
