When you find the volume of a triangle, remember to do this:
Step-by-step explanation:
Multiply the base times the height, then divide by two.
:)
The mistake is in the second triangle and is noticeable at first because the length of the leg is longer than the length of the hypotenuse.
Since this is a 30 60 90 triangle, you can use the properties that apply to them. I'm assuming that the leg with the length of 62ft is the given side. Using the rules, we know that x/2 is 62 (since the properties of a 30 60 90 triangle state that the shortest side is x/2). In order to find the hypotenuse (which is x), we can multiply both sides of the equation x/2 = 62 to get x = 124. To find the second leg, we need to use sqrt(3)*x/2, which when you plug in 124, gives 107.39. Andrea just switched the lengths of the second leg and the hypotenuse on accident.

A bag is filled with 100 marbles that are all the same size and shape each marble has one color the number of marbles in a colors are listed below 21 green 35 blue 18 red 26 yellow one marble is randomly selected from the bag which word best describes the probability of it being green
Answers
Answer: 21/100
Step-by-step explanation:
Number of green marbles = 21
Number of blue marbles = 35
Number of red marbles = 18
Number of yellow marbles = 26
Total number of marbles = 100
The probability of choosing a free marble will be:
= Number of green marbles / Tot number of marbles
= 21 / 100
Adriana opened a savings account and deposited $300.00 as principal. The account earns 6% interest, compounded annually. What is the balance after 9 years? Use the formula A=P1+ r n nt, where A is the balance (final amount), P is the principal (starting amount), r is the interest rate expressed as a decimal, n is the number of times per year that the interest is compounded, and t is the time in years. Round your answer to the nearest cent.

We can see that the rectangles are congruent meaning they can be mapped onto one another perfectly and therefore 13 and t make up a rectangle the same size and shape as the second one. This means that 13+t will add to 17 since the rectangle they make up is congruent to the second one

A sales associate in a store earns $325 per week, plus a commission equal to 4% of her sales. This week, her goal is to earn at least $475. At least how many dollars worth of sales does she need to make in order to hit her goal. (Hint: 4%=0.04)
Answers
Answer: She will need to sell at least ($3,750) of merchandise in order to reach her goal of $475 in one week.
Step-by-step explanation:
It is GIVEN that she earns a weekly salary of $325 and she needs $475.
Subtract $325 from $475 (425-325)=150.
Now we know that she needs $150 to earn on top of her salary to reach her goal of $475.
I used a calculator to plug in (x)0.04=150
I received 3750 as my answer
$3750 times 4%= 150

OC. 03064
OD. 0.3175
OE 0.2933
Answers
Answer:
D
Step-by-step explanation:
Here, we want to get the proportion that lies outside the given shown z-scores
Mathematically, that will be:
1 - proportion lying between the two z-scores
The probability lying between the two z-scores can be calculated using the normal distribution table
That will be;
P(-1.25 < x < 0.80)
From the table, this is;
0.68249
So the proportion lying outside will be;
1-0.68249 = 0.31751
This is approximately 0.3175

Each year, the Department of Water Works measures the chloride concentration level in the water. The first year, they found the chloride concentration changed by −135 mg/L .

Answers
Complete question :
Each year, the Department of Water Works measures the chloride concentration level in the water. The first year, they found the chloride concentration changed by −1 3/5 mg/L . It is estimated that the chloride concentration will change −2 1 /15 mg/L the next year. What is the total change that will likely occur in 2 years?
Answer:
- 3 2/3 mg/L
Step-by-step explanation:
Given that:
Change in concentration during first year = - 1 3/5 mg/L
Estimated change in second year = - 2 1/15 mg/L
Total change in concentration likely to occur over the 2 years:
This will be the sum of the concentration in the first and second year:
[-1 3/5 + (-2 1/15)] mg/L
-1 3/5 - 2 1 /15
-8 / 5 - 31 /15
L. C. M of 5 and 15 = 15
(-24 - 31) / 15
= - 55 / 15
= - 3 10/15
= - 3 2/3 mg/L
Graph the function and its parent function. Then describe the transformation. f(x) = x + 3
Please Help ASAP
Answers
We have graphed the function f(x) = x + 3 and it's parent function f(x) = x in the image attached below and the parent graph has been transformed 3 units up onto the y axis.
What is a function ?A function is a set of outputs for some set of inputs we can graph function s in x-y co-ordinate.
According to the given question we have to graph a function and it's parent function.
We know a parent function is a function which is free from any transformation so parent function of f(x) = x + 3 is f(x) = x.
f(x) = x implies y = x.
Some points are (-5,-5), (0,0), (2,2).
Graph of these function is attached in the image below.
f(x) = x + 3 here when x = 0 y = 3 implies the whole graph has been transformed 3 units up onto the y axis.
Image of this transformed graph has also been attached.
