Help me out plz struggling. Thx
Can someone help with this. Heads up it's ratios
Answer:
The median side measures 92 yards
Step-by-step explanation:
Let's call x, y, and z the measures of the sides of the triangle.
The ratios between them are:
[tex]\displaystyle \frac{x}{y}=\frac{4}{7}[/tex]
[tex]\displaystyle \frac{x}{z}=\frac{4}{2}=2[/tex]
The first ratio gives the relation:
[tex]\displaystyle y=\frac{7x}{4}[/tex]
The second ratio can be solved for z:
[tex]\displaystyle z=\frac{x}{2}[/tex]
Since the perimeter is 299 yards:
[tex]x+y+z=299[/tex]
Substituting the above relations:
[tex]\displaystyle x+\frac{7x}{4}+\frac{x}{2}=299[/tex]
Multiplying by 4:
[tex]4x + 7x+2x=1196[/tex]
Joining like terms:
[tex]13x=1196[/tex]
Dividing by 13:
[tex]x=1196/13[/tex]
x=92
Now calculate y:
[tex]\displaystyle y=\frac{7\cdot 92}{4}[/tex]
y = 161
[tex]\displaystyle z=\frac{92}{2}[/tex]
z=46
The median side measures 92 yards
At a football stadium, 5% of the fans in attendance were teenagers. If there were 10 teenagers at the football stadium, what was the total number of people at the stadium?
Answer:
200 people were at the stadium
Step-by-step explanation:
Let us represent the total number of people at the stadium = x
At a football stadium, 5% of the fans in attendance were teenagers. If there were 10 teenagers at the football stadium
Hence:
5% of total number of people = 10 teenagers
5/100 × x = 10
5x/100 = 10
Cross Multiply
5x = 100 × 10
5x = 1000
Divide both sides by 5
5x/5 = 1000/5
x = 200
The total number of people in the stadium is 200

A fireman is on the middle step of a ladder. (There are the same number of steps above him as below him.) If he goes down 4 steps, then up 7 steps, and then down 13 steps, he will be on the first step above the ground. How many steps does the ladder have?
Answer:
The ladder has 20 steps
Step-by-step explanation:
10 is the direct middle if you go down 4 that is 6, if you go back up 7 you get 13 and if you go back down 13 and you are on the first step 13-13 is 0, so the ladder has 20 steps.

Felipe sold t-shirts and hats at a festival. He made a $5 profit for each t-shirt he sold. He also made a profit of $40 from selling hats. If he made a total profit of $125, how many t-shirts did he sell?
Answer:
17 t-shirts sold
Step-by-step explanation:
If we assume that we don't need t find the number of hats, then we can say that the profit from -tshirts would be $125 minus 40 or $85
Then we can write the following equation of x is the number of t-shirts:
5x = 85
If we solve by diving both sides of the equation by 5:
5x/5 = 85/5
x = 17 t-shirts sold

What is the valur of y in the equation 2(3y - 6) = 0?
Answer:
y=2
Step-by-step explanation:
Distribute the 2 into 3y and -6:
6y-12=0
Move the -12 to the other side by adding both sides by 12:
6y-12+12=0+12
=
6y=12
divide both sides by 6:
y=2

A real estate agent earned commission of $8,785 for selling a house. If his rate is 7%, find the selling price of the house.
Answer:
$125,500
Step-by-step explanation:
Make "x" equal the selling price of the house
7% of x is the commission --->
.07 * x = 8785
x= 8785/ .07
x= 125500

help math pls geometry
Answer:
The point is (8,2)
Step-by-step explanation:
Is this a square or rectangle or rhombus, etc.? Yes, because all the lines are all parallel.
Are AB and FG are parallel to each other right? Yes, so that means whatever you do to F will happen to G and we can start on A, it goes 6 down, then two to the right.
Since all lines are parallel how many steps we do on A to get F, we have to do to B to get G. So, (8,2).

Suppose x, y, and z are different positive integers such that xy, yz, and zx are all perfect
squares. Must x, y, and z be perfect squares? Why or why not?
Answer: Yes, and the numbers are 4, 36, and 9
Step-by-step explanation:
Yes, because it x=4, y=36, and z=9 then 4 * 36=144, 144=12*12 4*9=36, 36=6*6, and 9*36=324, 324=18*18. As you can see they are all perfect squares and 4, 36, and 9 are all perfect sqaures too.

9+3.5g=11−0.5g i need this anwser plz help
Answer:
g = 1/2
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
9 + 3.5g = 11 - 0.5g
Step 2: Solve for g
Add 0.5g on both sides: 9 + 4g = 11Subtract 9 on both sides: 4g = 2Divide 4 on both sides: g = 1/2Step 3: Check
Plug in g into the original equation to verify it's a solution.
Substitute in g: 9 + 3.5(1/2) = 11 - 0.5(1/2)Multiply: 9 + 1.75 = 11 - 0.25Add/Subtract: 10.75 = 10.75Here we see that 10.75 does indeed equal 10.75.
∴ g = 1/2 is a solution of the equation.
Answer: g= 0.5
Step-by-step explanation:
Add
3.5g and 0.5g. to get
9+4g=11
then subtract 9 from the 11 and you should get 4g=2.
then divide 4 from 2 and you should get the answer of 2/4.
simplify it and you should get the answer g=0.5
urgent!! hal earns $5 doing chores for his parents. he also earns $10 a week for each dog, d, he walks.
Answer:
5+10d=x The dogs he walks are the ind variable and the total money he earns is the dep variable
Step-by-step explanation:
If he earns five dollars a week then that is a confirmed amount which means it’s just $5. Then for every dog he walks that’s $10 so if he walks 0 dogs then he gets $0.
The dogs he walks is ind because this variable is the variable that changes and effects the total whereas, the dep is the total because that’s what changes depending on the ind variable
