write the value of A.
PLEASE HELP ME OMG X
Answer:
Answer: 544
Step-by-step explanation:
The Surface Area of a Cuboid
Given a cuboid (rectangular prism) of dimensions x,y, and z, the surface area is calculated as follows:
[tex]S=2(xy+yz+xz)[/tex]
The dimensions of a given cuboid are x=28 cm, y=4 cm, z=5 cm, thus:
[tex]S=2(28*4 + 4*5+ 28*5)[/tex]
[tex]S= 2*272 = 544[/tex]
The surface area is [tex]544 cm^2[/tex]

Jenny bought 7 pounds of strawberries.
They were on sale for
$1.12 for every 2 pounds.
How much did Jenny pay?
Well every 2 pounds is 1.12 so if we take 1.12/2 we get 0.56 and then we have 1.12x3 for the 6 and that is 3.36 so if we add 0.56+3.36 we get 3.92 I HOPEE THIS IS RIGHT DONT COME AT ME IF WRONG

Which value of x makes the equation 0.75(x + 20) = 2 + 0.5(x - 2) true?
A. -64
B.64
C. 56
D.-56
The value of x for which equation 0.75(x + 20) = 2 + 0.5(x - 2) becomes true is equal to -56.
An equation is given which is 0.75(x + 20) = 2 + 0.5(x - 2).
We have to find out the value of x for which the equation becomes true.
What do you mean by algebraic expressions ?
The algebraic expressions are those which are made up of variables, constants and algebraic operations i.e., addition, subtraction, etc.
As per the question ;
The equation given is 0.75(x + 20) = 2 + 0.5(x - 2)
Let's solve to get the value of x.
⇒ 0.75(x + 20) = 2 + 0.5(x - 2)
⇒ 0.75x + 15 = 2 + 0.5 x - 1
⇒ 0.75x - 0.5x = 1 - 15
⇒ 0.25x = - 14
⇒ x = -14 ÷ 0.25
⇒ x = - 56
Let's check ;
0.75(x + 20) = 2 + 0.5(x - 2)
0.75 ( -56 + 20 ) = 2 + 0.5 ( -56 - 2 )
(0.75 × -56) + (0.75 × 20) = 2 + (0.5 × -56) + (0.5 × -2)
-42 + 15 = 2 -28 - 1
-27 = -27
Both sides are equal for value of x = -56.
Thus , the value of x for which equation 0.75(x + 20) = 2 + 0.5(x - 2) becomes true is equal to -56.

If there are 24 cats in the exhibit, how many tigers do you have?
Answer:
8
Step-by-step explanation:
If you have 8 loins and 4 tigers you add those up, you now have 12, if you have 24 cats that means that you double that, 12 x 2 =24 (boom) so now you know you just have to double 4 into 8.
Because for every 8 loins there are there are 4 tigers.

A scuba diver dives 243 feet into the ocean and then swims up 156
feet. What integer represents her final position relative to where
she started?
Answer:
Her final position would stop at -87.
Step-by-step explanation:
As she dove 243 feet into the ocean, that means she went down. Therefore she's currently at -243, however she swam up 156 feet ending her up at -87. If that was kinda complicated, then use -243+156 and you'll get -87.

Each of 8 students reported the number of movies they saw in the past year. This is what they reported: 18, 10, 20, 18, 12, 19,12, 11 find the mean and median number of movies that the students saw
Answer:
I. Mean = 15
II. Median = 15
Step-by-step explanation:
Given the following data;
Total number of students = 8
x = 18, 10, 20, 18, 12, 19,12, 11
F(x) = 18 + 10 + 20 + 18 + 12 + 19 + 12 + 11
F(x) = 120
To find the mean;
Mean = F(x)/n
Mean = 120/8
Mean = 15
To find the median;
Median refers to the middle number of a sorted data.
x = 10, 11, 12, 12, 18, 18, 19, 20
Middle numbers = 12 and 18
Median = (12 + 18)/2
Median = 30/2
Median = 15

Answer:
n^2(radical)7
Step-by-step explanation:
You have to find the square root of all the components separately. 7 is not a perfect square (one number*itself = perfect square, ex 4 is the perfect square of 2 because 2*2=4) but the n^4 can be simplified and brought outside of the radical. When finding the square root of variables with exponents they have to come out in pairs to create that "perfect square." Therefore when you move a variable, you basically divide the exponent by 2. so n^4 inside the radical becomes n^2 outside of the radical, leaving the problem itself to become n^2 (radical) 7.

A bus increases its position at a constant velocity for 12 s, and then it stops for 6 s.
Which option lists a true statement about how a distance-time graph would represent this motion?
A) The slope of the graph would be negative and constant for 12 s; then, the slope would be constant for 6 s because the slope represents velocity.
B) The slope of the graph would be positive and constant for 12 s; then, the slope would be 0 for 6 s because the slope represents velocity.
C) The slope of the graph would be positive and increasing for 12 s; then, the slope would be constant for 6 s because the slope represents velocity.
D) The slope of the graph would be negative and constant for 12 s; then, the slope would be 0 for 6 s because the slope represents the passing of time.
Answer:
D
Step-by-step explanation:
The slope of the graph would be negative and constant for 12 s; then, the slope would be 0 for 6 s because the slope represents the passing of time. Therefore, option D is the correct answer.
What is a constant velocity?Velocity gives us information about the rate of change of your position, meaning how fast your position is changing per unit time.
Given that, a bus increases its position at a constant velocity for 12 s, and then it stops for 6 s.
Here, rate of change is 12/6 = 2 s
Therefore, option D is the correct answer.

DO multiplication them convert like terms
Answer:
-3s² + 16s - 7
Step-by-step explanation:
Remember to follow FOIL. FOIL stands for (First, Outside, Inside, Last).
First, distribute -3s to s and -10, and 7 to -2s and -1:
-3s(s - 10) = -3s² + 30s
7(-2s - 1) = -14s - 7
Next, combine like terms:
-3s² + 30s - 14s - 7
-3s² + (30s - 14s) - 7
-3s² + 16s - 7
-3s² + 16s - 7 is your answer.

Find the slope and y-intercept
and write the equation.
(-98, 22), (0, -48)
m =
b=
Answer:
m = -35/49
c = -48
y = -35/49 x - 48
Step-by-step explanation:
Given the coordinate point
(-98, 22), (0, -48)
Slope m = y2-y1/x2-x1
m = -48 - 22/0 -(-98)
m = -70/98
m = -35/49
Substitute m = -35/49 and (0, -48) into the equation y = mx+c
-48 = 0(-35/49) + c
-48 = c
c = -48
Hence the y-intercept is -48
Get the equation
Recall that y = mx+c
y = -35/49 x - 48
