Answer:
141.12 cm^2
Step-by-step explanation:
The formula for area of a triangle is [tex]h(b1+b2)1/2[/tex]. you have that:
b1, or base 1, = 12.2
b2, or base 2, = 10.2
h, or height, = 12.6
so plug this into the formula:
[tex]12.6(12.2+10.2)1/2\\12.6(22.4)1/2\\12.6*11.2\\141.12[/tex]
Answer:
141.12cm^2
Step-by-step explanation:
First split the trapezoid into two shapes: a rectangle and a triangle.
The area of the rectangle is (10.2cm)(12.6cm) = 128.52cm^2
Finding the area of the triangle is a little trickier. In order to find the base of the triangle, subtract 12.2-10.2=2. The area of a triangle is defined as A=1/2bh, so let's plug in our values:
A = (1/2)(2)(12.6) = 12.6cm^2
Now, add them together.
12.6cm^2 + 128.52cm^2 = 141.12cm^2
A car is driving down a road at a normal speed of 50 miles per hour. It enters a hilly area of gradual incline and decline, where it must drive 50 miles up hill and then 50 miles downhill. If this 100 mile section of road takes 2.6 hours to traverse instead of the expected 2 hours (the time it would take if the road was completely flat) determine the speed that the hills add or subtract when going over.
Answer:
Step-by-step explanation:
I'm going to assume that the car goes 50-x mph uphill and 50+x mph downhill.
x ≅ 24 miles per hour
26 mph uphill and 74 mph downhill

Volume of a cylinder formula [tex]v=\pi r^{2} h[/tex]
h = 13ft
r = 10ft (20/2)
Then you solve
[tex]v=3.14*10^{2}*13\\\\v=3.14*100*13\\v=314*13\\v=4,082[/tex]
Is the point (3, 4) a solution to the linear equation 5x - 9y = 32?
Answer:
it equals -21 so no
Step-by-step explanation:
happy valentines!
Answer:
No, It does not.
Step-by-step explanation:
(3,4) means (x,y). When you insert 3 to x and 4 to y, You get this:
5(3)-9(4)=32
If you multiply 5 and 3, You get 15.
15-9(4)=32
If you multiply 9 and 4, you get 36.
15-36=32
If you subtract 15-36, you get -21.
This is why the answer is no because -21 does not equal 32
-21 ≠ 32

plot 2 2/3 and 1 7/9.
Answer:
Down below :)
Step-by-step explanation:
Hey there!
To plot a fraction on a graph you have to turn it into an improper fraction. In this case, the improper fraction for 2 2/3 is 8/3 and the improper fraction for 1 7/9 is 16/9.
*Note: To find the improper fraction of a fraction you must multiply the denominator by the whole number and then add the numerator.
With these two improper fractions...
8/3
16/9 (Simplify it down to 8/3 since both 16 and 9 go into 3)
You can now graph it. To graph, the numerator tells you how many times to go up and the denominator tells you how many times to go right. IF IT'S NEGATIVE IT WILL DO THE OPPOSITE IF THE NUMERATOR IS NEGATIVE IT WILL GO DOWN INSTEAD OF UP AND IF THE DENOMINATOR IS NEGATIVE IT WILL GO LEFT INSTEAD OF RIGHT.
8/9 means you need to start at the origin, (0,0) and go 8 up and 3 to the right. 8/3 means you start at the origin and go 8 up and 3 to the right. You will almost always start at the origin.
I really hope this helps :)

PLS HELP ME :(( what is the initial value of all linear functions that show a proportional relationship?
Answer:
The initial value, or y-intercept, is the output value when the input of a linear function is zero. It is the y-value of the point where the line crosses the y-axis. An increasing linear function results in a graph that slants upward from left to right and has a positive slope.

4(x)<$20
x<$20/4
x<$5
number of ice cream cones needed to make profit=20
number of ice cream cones sold so far= 6

Which of the decimals or fractions is not equal to 0.525 or 1/8
Answer:
0.18
Step-by-step explanation:
1/8 as a decimal is 0.125
1/8 un-simplified is 3/24
0.525 as a fraction is 21/40
So 0.18 is the only one that doesn't belong
0.18 is not equal to 0.525 or 1/8. Therefore Option (A) is the correct answer.
We need to find which of the decimals or fractions are not equal to 0.525 or 1/8.
How do convert decimals to fractions?The decimal numeral system is the standard system for denoting integer and non-integer numbers.
To convert decimal to fraction follow these steps
Step 1: Make a fraction with the decimal number as the numerator (top number) and a 1 as the denominator (bottom number).
Step 2: Remove the decimal places by multiplication. First, count how many places are to the right of the decimal. Next, given that you have x decimal places, multiply the numerator and denominator by [tex]10^{x}[/tex].
Step 3: Reduce the fraction. Find the Greatest Common Factor (GCF) of the numerator and denominator and divide both numerator and denominator by the GCF.
Step 4: Simplify the remaining fraction to a mixed number fraction if possible.
Now, from option (A)
0.18=18/100=9/25
From option (B)
0.125=125/1000=5/40=1/8
From option (C)
3/24=1/8
From option (D)
21/40=0.525
Therefore, option (A) is the correct answer.

Write the equation of the line that passes through the points (1,6) and (3, -4)
A. y = -5x + 11
B. y = x - 11
C. y = 5x +3
D. y = 2x -3
Answer:
A. y = -5x + 11
Step-by-step explanation:
The general form of the equation of a line is given as
y - y1 = m (x - x1)
where m is the slope and x1, y1 are the coordinates of a point on the line.
m = (y2 - y1)/(x2 - x1)
Given the points (1,6) and (3, -4)
m = (-4-6)/(3-1)
=-10/2
= -5
The equation of the line will be
y - 6 = -5(x -1)
y - 6 = -5x + 5
Add 6 to both side
y = -5x + 5 + 6
y = -5x + 11
Option A

Step-by-step explanation:
Choose the inverse of y = x2 - 10x.
y = 2√x-25-5
y = fx-25 +5
y = + 1+25 – 5
y = f(x+25 +5
=Y2-10Y
We move all terms to the left:
-(Y2-10Y)=0
We add all the numbers together, and all the variables
-(+Y^2-10Y)=0
We get rid of parentheses
-Y^2+10Y=0
We add all the numbers together, and all the variables
-1Y^2+10Y=0

The inverse of the given function is y=±√(x+25)+5. Therefore, the option D is the correct answer.
What is inverse function?Inverse function is represented by f⁻¹ with regards to the original function and the domain of the original function becomes the range of inverse function and the range of the given function becomes the domain of the inverse function. The graph of the inverse function is obtained by swapping (x, y) with (y, x) with reference to the line y = x.
The given function is y=x²-10x
Replace x with y and y with x.
x=y²-10y
x=y(y-10)
y=x/(y-10)
So, the equation is non-invertible, the equations of the graph gained by reflecting over y = x
y=±√(x+25)+5
Therefore, the option D is the correct answer.
