2(5*4)=40
2(15*5)=150
Total = 310mm^2
Second picture:
7k+14
36d+144
Answer:
surface area = 2(5 × 4) + 2(15 × 4) + 2(15 × 5) = 310 mm²
7(k + 2)
= 7×k + 7×2
= 7k + 14
12(3d + 12)
= 12×3d + 12×12
= 36d + 144
surface area rectangular prism = 2(4 × 5) + 2(15 × 4) + 2(15 × 5) = 310 cm²
5x + 7x - 2
= 12x - 2
4 + 3g - g + 2g

A line passes through the point (-8,4) and has a slope of . -5/2
Write an equation in slope-intercept form for this line.
Answer:
Y= -5/2x +16
Step-by-step explanation:
To solve this, understand that (-8,4) is (x,y)
And Slope intercept form is y=mx +b
Since you have a possible x and y with - 8 and 4, sub that in making it 4=m(-8) + b
We also have the Slope (or M) which is -5/2, sub that in and get 4 = -5/2 (-8) + b
Do the multiplication and get 4= 40/2 +b
Simplify to 4= 20 + b
Then re-arrange to have the unknown (b) on one side and known on the other (when you move a number over the equal sign its sign, positive or negative, becomes the opposite)
B= 20-4
Subtract
B= 16
Now you know the b and can add it to your equation,
Y= -5/2x +16
Answer:
y = -5/2x - 16.
Step-by-step explanation:
First use the point-slope form of a line:
y - y1 = m(x - x1)
y - 4 = -5/2(x - (-8))
y - 4 = -5/2x - 40/2
y = -5/2x - 20 + 4
y = -5/2x - 16.
If f(x) = 2x and g(x) = 5x, what is f(g(x)) when x = 3?
Hey there!
RANDOM FACTOID:
‘‘f(x)’’ or ‘‘g(x)’’ is understood to be “y”
f(x) = 2x
f(x) = 2(3)
f(x) = 2 + 2 + 2
f(x) = 4 + 2
f(x) = 6
Therefore, your answer is: f(x) = 6
g(x) = 5x
g(x) = 5(3)
g(x) = 5 + 5 + 5
g(x) = 10 + 5
g(x) = 15
Therefore, your answer is: g(x) = 15
OVERALL ANSWER: f(x) = 6 or g(x) = 15
Good luck on your assignment & enjoy your day!

Help plz , math equation !!
Answer:
We are given the table of a linear function
Since we have to find the equation of the function in the slope-intercept form,
we require the slope as well as the y-intercept
Finding the slope:
We know that slope of a line is Rise / Run
Since from the graph, we notice that the difference of 2 consecutive x-coordinates is 1
Hence, we have the x-coordinates at an interval of 1 and since the slope of a line is defined as the units ascended by the line after covering 1 unit in the x-coordinate
change in y = y[tex]_{n}[/tex] - y[tex]_{n-1}[/tex] (where n is the number of row in the table)
change in y = 31 - 23
change in y = 8 = Rise
Run = 1 (Since the interval in the table is 1)
Slope = Rise / Run
Slope = 8 / 1
Slope = 8
Finding the y-intercept:
We need the y-coordinate at x = 0
Going up from the third row, we notice that for every unit decreased in the x-coordinate , 8 units of the y-coordinate are decreased (since the slope =8)
In that case, the y-coordinate of every decreased x-coordinate will be 8 less than the last one
so we can say that the y-coordinate of x = 1 will be 8 less than 23 since x=1 is one less than x = 2
similarly, we can also say that the y-coordinate of x = 0 will be 8 less than (23-8) since x = 0 is one less than x = 1
Therefore, the y-coordinate at x =0
y = (23-8-8)
y-intercept = 7
Making the Equation:
We need to write the equation in the form:
y = ax + b (where a is the slope of the line and b is the y-intercept)
Replacing the known values, we get
y = 8x + 7
Therefore, the equation of the formula shown in the table is y = 8x + 7
In a two digit number. the unit digit is thrice the tens digit. if 36
is added to the number, the digits interchange their place. find the number
Answer:
Step-by-step explanation:
answer: the original number is 62.
Given :
Units digits is thrice the tens digit
The digits interchange when - 36 is added
To find :
The number
Solution :
✯
Let the digits be -
Units place as 3y
Tens place as 10(y)
⇒ 10(y) + 3y
⇒ 10y + 3y
⇒ 13y --------- (Orignal Number)
✯
Let the digits be -
Units place as y
Tens place as 10(3y)
⇒ 10(3y) + y
⇒ 30y + y
⇒ 31y --------- (Number with reversed digits)
✯
The number gets reversed when 36 is added to it.
⇒ 13y + 36 = 31y
⇒ 13y - 31y = - 36
⇒ 18y = 36
⇒ y = 36/18
⇒ y = 2
✯
⇒ 13y
⇒ 13(2)
⇒ 26
✯
The units place should be thrice of the tens place,
⇒ 2 × 3 = 6
Units place is 6
Reversed digits are 62,
⇒ 26 + 36 = 62
⇒ 62 = 62
The Orignal Number is 62.

A line passes through the point (7,9) and has a slope of 2.
Write an equation in slope-intercept form for this line.
Answer: y = 2x - 5
Step-by-step explanation:
slope- intercept form is always written as y = mx + b, where m = slope, and b is the y-intercept.
To find b, substitute the point and the slope into the equations, you will get:
y = mx + b
9 = 2(7) + b
9 = 14 + b
-5 = b
Plug in m and b into the equation, we get:
y = mx + b
y = 2x + (-5)
y = 2x - 5
The equation is y=mx+b.
My question is, is ‘b’ supposed to be in decimal form or in fraction form??
Answer: both ways are acceptable
Step-by-step explanation: When writing equations of lines in this form,
we usually keep the "b" value or the constant term as a fraction.
However, if you prefer decimals, you can absolutely change
it to a decimal to visualize is better if you'd like, it's really your choice.
For example, if the equation of a line was y = -3/4x - 7/4, I could leave
it how it is or I could change the -7/4 to -1.75 giving me y = -3/4x - 1.75.

a cell phone tower services about 1,256sq. miles what is the radius?
Start with the formula for finding the area of a circle.
A=πr2
First, substitute the given information in the equation. You have the area and you know that pi is 3.14.
153.86=(3.14)r2
Next, divide the area by pi. This will help to get one step closer to figuring out the radius.
3.14)153.86¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
Remember, when you divide decimals, to move the decimal two places in the divisor and the dividend.
314)15386¯¯¯¯¯¯¯¯¯¯¯¯¯¯
314)15386¯¯¯¯¯¯¯¯¯¯¯¯¯¯ 49− 1256 –––––––– 2826 − 2826–––––––0
So far, the answer is 49, but that is not the radius because r2 is on the right side of the equal sign.
49=r2
Then, you need to figure out which number times itself is equal to 49. You can figure this out by finding the factors of 49.
7×7=49
Now, you know that the radius is 7 inches because 7×7=49.
The radius is 7 inches.
Finally, to figure out the diameter, which is twice the radius, multiply the radius by 2.
7×2=14
The diameter is 14 inches.
hope this helps.
The radius covered by the tower will be 20 miles.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.
Given that a cell phone tower services about 1,256sq. miles. The area of the circle will be calculated by the formula,
Area = πr²
1256 = π x r²
r² = ( 1256 / π )
r² = 400
r = √400
r = 20 miles
Hence, the radius of the circle will be 20 miles.

Darryl is a baseball player who has a 0.250 batting average. That means that over some period of time, Darryl had a hit in 1 out of 4 at bats. Consider the experiment where darryl has 4 at bats in a game and observes whether or not he gets a hit each time.
The number of hits of the baseball player when batting is the average of hit
The expected number of hits in a bat of 4 is 1
How to determine the number of hitsThe given parameters are:
The battling average, p = 0.250
The number of bats, n = 4
The number of hits in the bat is the average of hit, and it is calculated as:

The likelihood of an event occurring may be described as being certain, more likely, equally likely, less likely, or impossible
We will find the probability of getting each color of marble, and we will see that getting red and blue is equally likely, while getting green is less likely.
How to find the probabilities for each color of marble?
If we draw a marble at random from the box, all of them will have the same probability of being drawn.
Then the probability of getting a given color is given by the quotient between the number of marbles of that color and the total number of marbles.
Probability of getting red:
P = 11/25 = 0.44 This is really close to 50%, so this is equally likely.
Probability of getting blue:
P = 11/25 = 0.44 This is really close to 50%, so this is equally likely.
Probability of getting green:
P = 3/25 = 0.12 This is really close to 0%, so this is less likely.

This answer is at best a guess. It seems to me that you are constructing a circle graph, and I would like that confirmed.
The total number of people in the survey is
Total in survey = 96 + 60 + 24 + 96 + 204
Total in survey = 480
A circle contains 360 degrees.
480 people have 360 degrees of circle room
1 person has x degrees of circle room
480 / 1 = 360 / x
Cross multiply
480 x = 360 *1 Divide both sides by 480
x = 360 / 480
x = 0.75
One person takes 3/4 of a degree of the circle.
So the number of people wanting to go to the UK would be
96 * 0.75 = 72 degrees,
