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.

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.

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.

Step two:
The compound interest formula is
[tex]A= P(1+r)^t\\\\A= P(1+0.06)^9\\\\A= 300(1+0.06)^9\\\\A= 300(1.06)^9\\\\A= 300*1.689\\\\A=506.7[/tex]

OA 02881
OB. 0.3102
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

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

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
