Answer:
50mph
Step-by-step explanation:
Say for example car A increases by 10 miles per hour and car B decreases by 10 miles per hour. If car A2 = car B3 then by eliminating a few numbers and finally get to 50 you get the following equation.
A = 50+10
b = 50-10
A = 60
B = 40
A2 = 120
B3 = 120
120 = 120
what is the answer for 5/11x + 2/3x - 1/6x = -189
Answer:
x = -198
Step-by-step explanation:
5/11 x + 2/3 x - 1/6 x = -189
66(5/11x + 2/3x - 1/6x) = 66(-189)
30x + 44x - 11x = -12474
63x = -12474
x = -198
Answer:
x = -210
Step-by-step explanation:
\(\frac{5}{11x} + \frac{2}{3x} - \frac{1}{6x} = -189\)
\(\frac{37}{33x} - \frac{1}{6x} = -189\)
\(\frac{21}{22x} = -189\)
0.9x = -189
\(x = \frac{-189}{0.9}\)
x = -210

Answer:
its D
12,455 + x = 23,894
x = 10,560
Step-by-step explanation:
Let's say that the variable 'x' represents the salaries for the second month, so out equation would be:
10,205 + x = 23,894
To solve, we must isolate the variable by subtracting 12,455 from both sides:
10,205 + x = 23,894
-10,205 -10,205
x = 10,560
So, the second month's salary was $10,560
Step-by-step explanation:
Answer: x = $30,560
Step-by-step explanation:
1. Let the second month payment be x
2. The first month + The second month = both of the months
3. So substituting: 10,205 + x = 40,765
4. Subtract 10,205 from both sides: x = 30,560

Answer:
525
Step-by-step explanation:
If it's just asking to find the average of heads then times it by 20 then just do 32+28+21+24 to get 105 and divide it by 4 to get 26.25 then times it by 20 since this is the average of 50 throws and it's asking for the average of 1,000 throws which is 525

An equilateral triangle has sides of length 10 cm.
**DIAGRAM IN PICTURE**
a. Calculate the perpendicular height, h, of the triangle.
b. Calculate the area of the triangle.
Give your answers correct to one decimal place. 10 cm 10 cm 10 cm
Answer:
a. 8.7cm
b. 43.5cm squared
Step-by-step explanation:
a. draw the triangle with a side length of 10cm, and measure the height which is 8.7cm.
b. formula to find the area of a triangle: (base into height) divided by 2 ((b x h) / 2)
the base is 10
the height is 8.7
(10 x 8.7)/2 = 87/2 = 43.5 cm squared
We have that 3 * f(x) + 4 * g(x) = h(x) where f(x), g(x), and h(x) are all polynomials in x. If the degree of f(x) is 8 and the degree of h(x) is 9, then what is the minimum possible degree of g(x)?
9514 1404 393
Answer:
9
Step-by-step explanation:
Adding polynomials causes like terms to be combined. The sum cannot have a degree higher than the degree of any of the terms in the sum. If the degree of f(x) is 8, then the degree of g(x) must be 9 in order for the sum to be of degree 9.
The length of a rectangle is 5 cm longer than its width.
If the perimeter of the rectangle is 30 cm, find its area.
Equation To write :2 {x+ ( x+5) }=30
Let's solve your equation step-by-step.
2(x+x+5)=30
Step 1: Simplify both sides of the equation.
2(x+x+5)=30
(2)(x)+(2)(x)+(2)(5)=30(Distribute)
2x+2x+10=30
(2x+2x)+(10)=30(Combine Like Terms)
4x+10=30
4x+10=30
Step 2: Subtract 10 from both sides.
4x+10−10=30−10
4x=20
Step 3: Divide both sides by 4.
4x
4
=
20

x=5
So... x+5=10.
Area =5x10=50 cm squared.
Answer:
5
Step-by-step explanation:
Okay, so P = perimeter, and the problem says P = 30
Let's call x the width, and y is the length.
In the perimeter formula, 2X + 2Y = P
so 2X + 2Y = 30
The problem also tells us that that x = y+5, so now let's do some substituting and replace X with Y+5
2(y+5) + 2Y = 30
2y+10 +2Y = 30
4y+10=30
-10. -10
4y=20
Y=5

Answer:
A: 4
Step-by-step explanation:
So first you can move the 2^-5 to the denominator, making the equation (2^2) (4^3) / (2^5) (2)
Then simplify the terms so you end up with (4)(64) / (32) (2)
Then multiply the denominator so you end up with (4) (64) / (64)
Since both the denominator and numerator have 64, those cancel out leaving you with 4

Step-by-step explanation:
The volume of a pyramid can be found using the following formula:
\(\boxed{\large \textsf{$V=\frac{1}{3}Ah$}} \large \textsf{ where:}\\\\ \normalsize \textsf{$\bullet{\,V = $ volume of pyramid$}$}\\ \normalsize \textsf{$\bullet{\,A = $ base area$}$}\\ \normalsize \textsf{$\bullet{\,h = $ perpendicular height$}$}\)
Note: in the question, it states that base area = 12 cm³, however, this is an error (typo), and the area is 12 cm², since area is only in 2 dimensions. length and width, whilst volume is in 3 dimensions. length, width, and height.
Now, we can plug in our data into the formula:
\(\large \textsf{$40=\frac{1}{3}12h$}\\\\ \large \textsf{$40=4h$}\\\\\boxed{\boxed{\large \textsf{$\therefore h = 10$ cm}}}\\\)
