Please check explanations
Step-by-step explanation:
Mathematically, the area of a triangle
A = 1/2 * b * h
b is base, h is height
For 12 square units, we can have a base of 6 and a height of 4
By tripling the dimensions for the second triangle, we will have a triangle of 18 by 12
So the new area is;
A = 1/2 * 12 * 18
That was how we got 108 square units

3(2y + 4) = 7y + 4 - y y =
I cant get an accurate answer for this problem Help!
Answer:
No solutions
Step-by-step explanation:
3(2y + 4) = 7y + 4 - y
~Simplify both sides
6y + 12 = 6y + 4
~Subtract 12 to both sides
6y = 6y - 8
~Subtract 6y to both sides
0 = 8
Best of Luck!
Evaluate, if x = -12, y = -4, and
z is = 9
Calculate the average rate of change for the given graph from x = 3 to x = 5 and select the correct answer below.
Answer:
Average rate of change between x = 3 to x = 5 is 0.
Step-by-step explanation:
Given quadratic function s passing through two points (3, 0) and (5, 0).
Average rate of change of a function between x = a and x = b is given by,
Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
From the graph attached,
Average rate of change between x = 3 to x = 5 will be,
= [tex]\frac{f(5)-f(3)}{5-3}[/tex]
= [tex]\frac{0-0}{5-3}[/tex]
= 0
Therefore, average rate of change between x = 3 to x = 5 is 0.
Answer: The average rate of change for the given graph from x=3 to x=5 is 0

In rectangle PLAN, PT = x + 3 and TL = 3x - 11. What are the lengths of PA and NL?
Answer:
PA = 20 units
NL = 20 units
Step-by-step explanation:
Property of a rectangle,
"Diagonals of a rectangle are equal in measure and divide each other in two equal parts"
By using this property,
PT = TL
(x + 3) = (3x - 11)
3x - x = 11 + 3
2x = 14
x = 7
Length of PT = (x + 3) = 10
Length pf PA = 2(PT) = 20 units
Length of NL = PA = 20 units

Answer:
(21, 8)
(3, 2)
(-15, -4)
Step-by-step explanation:
First we need to create the equation in y=mx +b form.
(m) is slope [rise/run]
(b) is y intercept
The line crosses the y axis at (0,1) so that's our (b) and to find slope we will find a point where ethe line crosses a point, I'll use (0, 1) and see how many it has to go to reach the next point. In this case it has to go up 1, and right 3.
Our slope is 1/3.
y=1/3x+1.
Now we can start applying the given points.
(21, 8)
8=1/3(21)+1
8=7+1
8=8.
(21, 8) is a solution.
(3, 2)
2=1/3(3)+1
2=1+1
2=2
(3, 2) is a solution.
(-15, -4)
-4=1/3(-15)+1
-4=-5+1
-4=-4
(-15, -4) is a solution.
(12, 9)
9=1/3(12)+1
9=4+1
9=5
(12, 9) is not a solution.
(-6, 1)
1=1/3(-6)+1
1=-2+1
1=-1
(-6, 1) is not a solution.
Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

A manager of the credit department for an oil company would like to determine whether the mean monthly balance of credit card holders is equal to $75. An auditor selects a random sample of 100 accounts and finds that the mean owed is $83.40 with a sample standard deviation of $23.65. If you were to conduct a test to determine whether the auditor should conclude that there is evidence that the mean balance is different from $75, which test would you use? a) Z-test of a population mean b) Z-test of a population proportion c) t-test of population mean d) t-test of a population proportion
Answer:
c) t-test of population mean
Explanation:
The t-test statistic is used in hypothesis testing. Here we would use a one sample t test to test our hypothesis. The one sample t test measures the statistical difference between the hypothesized mean and the sample mean. In a one sample t test or single sample t test, a test variable is measured against a test value.
Example we compare our test variable to the hypothesized mean value $75 above.
The t test is used instead of z score when standard deviation is unknown.
Using the t test, we either accept or reject the null hypothesis given alternative hypothesis.
7/15 - 2/5
please can someone do a step by step? thank you
Answer:
1/15
Step-by-step explanation:
1.) Make the denominator equal by turning the 5 into a 15 (In order to subtract it properly)
2.) Make the 2 correspond with the denominators. In this case multiply by 3 because 5 goes in to 15 3 times. Equation Now: 7/15 - 6/15
3.) Subtract the numerators to get your answers
4.) Final Answer: 1/15

2 pens in each pack of black pens 5 pens in each pack of red pens 6 pens in each pack of green pens On Monday number of packs sold of black, red and green pens = 7 : 3 : 4 A total of 212 were sold.
Answer:
The number of green pens sold is 96.
Step-by-step explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
A shop sells packs of black pens, packs of red pens and packs of green pens. There are:
2 pens in each pack of black pens
5 pens in each pack of red pens
6 pens in each pack of green pens
On Monday, number of packs of black pens sold : number of packs of red pens sold : number of packs of green pens sold = 7:3:4
A total of 212 pens were sold.
Work out the number of green pens sold.
The explanation of the answer is now given as follows:
Since the ratio is given in packs of pens, we have to first convert it to number of pens based on the number of pens in each pack. Therefore, we have:
7:3:4 is converted to (7 * 2) : (3 * 5) : (4 * 6) = 14 : 15 : 24
Based the new ratio, we have:
Weight of contribution of the green pens to the total number of pens sold = 24 / (14 + 15 + 24) = 24 / 53 = 0.452830188679245
The number of green pens sold can now be calculated as follows:
Number of green pens sold = Total pens sold * Weight of contribution of the green pens to the total number of pens sold = 212 * 0.452830188679245 = 96
Therefore, the number of green pens sold is 96.

richard and teo have a combined age of 42 richard is 12 years older than twos age how old are richard and teo
Answer:
teo= 15 years old
richard= 27 years old
Step-by-step explanation:
richard=r
teo=t
r + t=42
t + 12= r
u can use substitution here
(t+12) + t=42
2t + 12= 42
2t=30
t= 15
to find r, you just do 15 + 12= 27
to check you can do 27 + 15= 42
The age of Richard and Teo will be 27 years and 15 years, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Richard and Teo are 42 years old. Richard is 12 years older than Teo.
Let x be the age of Richard and y be the age of Teo. Then the equation is given as,
x + y = 42 ...1
x = y + 12 ...2
From equations 1 and 2, then we have
y + 12 + y = 42
2y = 30
y = 15
Then the value of the variable 'x' is given as,
x = 15 + 12
x = 27
The age of Richard and Teo will be 27 years and 15 years, respectively.
More about the solution of the equation link is given below.
