speed? (per single hour – unit rate)PLEASE HELP MEE
Answers
answer: 68
work:
all you basically do is just divide 272 by 4
If Ralph drove 272 miles in 4 hours then 68 miles per hour is the average speed
What is Division?
A division is a process of splitting a specific amount into equal parts.
Given that Ralph drove 272 miles in 4 hours
We need to find his average speed
The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time
Speed=Distance/ Time
Average speed=272/4
=68 miles per hour
Hence, if Ralph drove 272 miles in 4 hours then 68 miles per hour is the average speed

a rectangular tank is 76cm long, 50cm wide and 40cm high, how many litres of water can it hold?
Answers
Answer:
Volume of a cuboid or rectangular tank = side × side × side
or
volume of a cuboid or rectangular tank = length× width × height
volume of the rectangular tank = 76 × 50 × 40
volume of the rectangular tank = 152000cm³
Therefore the rectangular tank can hold 152000cm³ litres of water

Let's solve your equation step-by-step.
−6=3/8x−2+
1/8x
Step 1: Simplify both sides of the equation.
−6=3/8x−2+1/8x
−6=3/8x+−2+1/8x
−6=(3/8x+1/8x)+(−2)
(Combine Like Terms)
−6=1/2x+−2
−6=1/2x−2
Step 2: Flip the equation.
1/2x−2=−6
Step 3: Add 2 to both sides.
1/2x−2+2=−6+2
1/2x=−4
Step 4: Multiply both sides by 2.
2*(1/2x)=(2)*(−4)

Answers
Answer:
[tex]A=5024\ cm^2[/tex]
Step-by-step explanation:
Father will make an ornamental fish pond. The pool is circular with a diameter of 80 cm, the area of land needed to make a pool is ??
The diameter of a circular pool, d = 80 cm
It means that,
Radius, r = d/2
r = 40 cm
We need to find the area of the land needed to make a pool. The area of a circular path is given by :
[tex]A=\pi r^2[/tex]
Put the values in the above formula.
[tex]A=3.14\times (40)^2\\\\A=5024\ cm^2[/tex]
So, it will require [tex]5024\ cm^2[/tex] area of land to make a pool.

A company offering short term loans agrees to lend Nick $1,200 . The amount (plus interest) is repayable in one year, and the interest rate is 12% per month. What is the total amount that must be repaid? Give your answer in dollars to the nearest dollar. Do not include commas or the dollar sign in your answer. For example if your answer is $1,234.56 enter 1235 .
Answers
Answer:
The total amount is 1214.4
Step-by-step explanation:
Given
principal p=$1200
interest rate r= 12%= 12/100= 0.12
time t= 1
n= 12
we know that the compound interest formula is
A=p(1+r/n )^nt
A=1200(1+0.12/12)^1*12
A=1200(1+0.01)^12
A=1200(1.001)^12
A=1200*1.012
A=1214.
Answer:
Correct answers:
$2928$
Step-by-step explanation:
$2928$
We express the interest r in decimal form, so we have r=12%=12100=0.12. The principal is P0=$1,200, so the interest is I=P0⋅r⋅t=$1,200⋅0.12⋅12=$1,728. The interest paid is $1,728, so the total amount repayable is $1,200+$1,728=$2,928.

x = -1 , y = 4Step-by-step explanation:
x + 2y = 7 ⇒ x = 7 - 2y
- 2x + 3y = 14
- 2(7 - 2y) + 3y = 14
-14 + 4y + 3y = 14
-14 +7y +14 = 14 +14

g(x) = 2 log(x - 1)
what is the inverse
Answers
Answer:
[tex]g^{-1}(x)=1+10^{x/2}[/tex]
Step-by-step explanation:
Inverse Function
Let's call:
[tex]y=2 log(x-1)[/tex]
Divide by 2:
[tex]y/2=log(x-1)[/tex]
Assuming the base of the log is 10, apply exponential base 10:
[tex]10^{y/2}=x-1[/tex]
Solving for x:
[tex]x=1+10^{y/2}[/tex]
Swap variables:
[tex]y=1+10^{x/2}[/tex]
Calling this function the inverse:
[tex]\boxed{g^{-1}(x)=1+10^{x/2}}[/tex]

What is the slope of the line shown.
Answers
Answer:
The answer is negative one half. If I am wrong let me know because the picture is a little hard to read.
Step-by-step explanation: To find the slope, you look at the Y axis and see where the line crosses perfectly(or goes through) the Y axis first. Then, you look at the x axis and see where the line crosses perfectly on the x axis. For example, the line crosses the Y axis at negative, and the line crosses the X axis at positive 2. The vertical line is the y axis and the horizontal line is the x axis.

Answer:
(x - 12)(x + 2)
Step-by-step explanation:
Given
x² - 10x - 24
Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (- 10)
The factors are - 12 and + 2 , since
- 12 × + 2 = - 24 and - 12 + 2 = - 10 , thus
x² - 10x - 24 = (x - 12)(x + 2) ← in factored form

Answers
Answer:
[tex]\frac{5}{2}[/tex]
Step-by-step explanation:
For this situation we have the equation [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex], where each variable represents a coordinate (e.g. in this case 4 could be [tex]y_{1}[/tex]). So first, let's define which coordinates will be the values of these variables:
(3,4): [tex]x_{1}, y_{1}[/tex]
(5,9): [tex]x_{2}, y_{2}[/tex]
Now we need to replace each variable with its given value: [tex]m = \frac{9-4}{5-3}[/tex]
And then do the subtraction to simplify: [tex]m=\frac{5}{2}[/tex]
Therefore, the slope of the line that passes through the points (3,4) and (5,9) is [tex]\frac{5}{2}[/tex].

find the value of x !
Answers
Answer:
x = 32
Step-by-step explanation:
So we are given the measures of two of the three interior angles. 98° and 50°. We are also given that the value of the third interior angle is equal to x°. Remember, the sum of the interior angles of a triangle is 180°. Knowing this, we can make the equation:
x + 98 + 50 = 180
Now we solve for x. Subtract 50 from both sides.
x + 98 = 130
Subtract 98 from both sides.
x = 32
So the value of x is 32.
