Answer:
24179 square inches
Step-by-step explanation:
In ΔRST, r = 620 inches, s = 840 inches and t=230 inches. Find the area of ΔRST to the nearest square inch.
We use the formula
Heron's formula = √s(s - a)(s - b)(s - c)
Where s = a + b + c/2
Solving for s
s = 620 + 840 + 230/2
s = 845
Solving for the area of the triangle
= √845 × (845 - 620) × (845 - 840) × (845 - 230)
= √584634375
= 24,179.213696893 square inches
Approximately = 24179 square inches

I also have trouble with this sry :(
A salesperson is selling cooking sets for $120 each. The salesperson receives 22.5% of the sales prices as commission. The salesperson sells a total of 4 units on Monday but an unknown number of units on Tuesday. The salesperson made a combined total of $351 commission for those two days. Write an equation that could be used to find the number of cooking sets x sold on Tuesday. Then solve the equation.
[Please help!]
Answer:
4(120)(.225) + x (120)(.225) = $351
9 units sold on Tuesday
Step-by-step explanation:
1. You can easily figure how much money was made on Monday by multiply the total units sold by the price per unit by the commission in decimal form. Here you get $108.
2. Subtract that $108 from the $351 made on both days and you get $243 made on Tuesday.
3. The equation is now the unknown number of units sold (x) times the price ($120) times the commission is decimal form (.225) equals $243.
4. Since 120 times .225 is equal to 27, the equation now becomes 9x is equal to 243.
5. Divide 243 by 27 for your answer.

Step-by-step explanation:
Answer:
so it is more than 1 quart, but less than 1.5 quarts, so narrow down the answer choices
1. w could be 3/4? no. 3/4 is less than 1
2. w could be 1. no. the bottle contains more than 1 quart.
3. w>1 it could be, but it dosent specify what w is, so we have no way of knowing if its over or under 1.5
4. w could be 4/3. yes that works. in mixed form it would be 1 and 1/3, it is more than one, but less than 1.5
5. w could be 5/3 no. 5 over 3 in mixed forn is 1 and 2/3, witch is over 1.5
6. w>1.5 nope. it cant be over 1.5
THE ANSWER IS THE 4TH ANSWER. W COULD BE 4/3

Step-by-step explanation:
Consider this exponential equation:
f(x) = 5(3)^x
Identify the following:
Domain
Range
Y-intercept
Step-by-step explanation:
F( x ) = 5 (3) ^ x
Y intercept
Let x = 0
f(0) = 5× 3 ^ 0
f(0 = 5 × 1
f(0) = 5
X intercept
let y = o
0 = 5 × 3 ^x
No x intercept/ zero
therefore
Vertical intercept (0; 5)

2. How many zeros does this parabola have?
this is the question
Answer: 127.795 in^2
Step-by-step explanation:
The area of any triangle is [tex]\frac{1}{2} \cdot \text{base} \cdot \text{height}[/tex][tex]\frac{1}{2} \cdot \text{base} \cdot \text{height}[/tex]
The surface of this pyramid is composed of three slanted triangles and the base.
Area of slanted sides (3 of them):
The base of each is 6.1 -- the sides of the bottom triangle all have the same length. The height of a slanted side is 12.2 .
Area of one slanted side is .5(6.1)(12.2) = 37.21
There are 3 identical sides, so the area of all 3 is 3 x 37.21 = 111.63 .
Area of the pyramid's base:
The base of that triangle is 6.1, and its height is 5.3, so its area is
.5(6.1)(5.3) = 16.165
The total area of all four faces is 111.63 + 16.165 = 127.795
Chris can do 30 pushups in 60 seconds. At this rate
how many pushups can he do in 360 seconds?
Answer: 180 pushups
Step-by-step explanation: First set up a proportion. The proportion would be 30 pushups over 60 seconds equal x over 360 seconds. Then you would cross multiply which is 60 times x which is 60x .After that do 30 times 360 which is 10,800.Now you have 60x = 10,800.NOw divide both sides by 60 which gives you 180 as x.

Can someone help me find an equation for both of these ❤️
Answer and Step-by-step explanation:
First equation:
y = -4x + 9
This equation has a negative slope (a slope that does downwards) and has a positive y-intercept (at (0, 9)).
Second Equation:
y = -4x - 4
This equation is parallel to the first line because it has the same slope. It also has a negative y-intercept (at (0, -4)).

what is 700 times 10
Answer:
7000
Step-by-step explanation:
Here we will show you and explain using simple algebra how to calculate "what" in this sentence: "700 is 10 times as much as what?"
When using algebra to solve a word problem, read the word problem thoroughly to make sure you understand exactly what it is asking.
To clarify, "700 is 10 times as much as what?" is the same as "700 is 10 times as much as x", "What is x?" or "10 times a number will have a product of 700 - what is that number?"
Based on that information, we created the following equation to solve "700 is 10 times as much as what?":
10 • x = 700
To solve for x, we divide both sides by 10 to get x by itself. Here is the math to illustrate:
10 • x = 700
10x = 700
10x/10 = 700/10
x = 70
Thus, the answer to "700 is 10 times as much as what?" is 70.
In other words, 700 is 10 times as much as 70 because 10 times 70 equals 700. Note that the answer is rounded if necessary.
The multiplication 700 and with the number 10 gives the result 7000.
In multiplication, the numbers being combined are called factors, and the result is called the product.
When you multiply 700 by 10, you are essentially adding 700 to itself 10 times.
Mathematically, it can be represented as:
700 * 10 = 700 + 700 + 700 + 700 + 700 + 700 + 700 + 700 + 700 + 700
= 7,000
So, 700 times 10 equals 7,000.
