Is this correct? Ive done this a million times and they always come out the same, but I still get it wrong.
Answers
Answer:
No, the correct answer is 32cm.
Step-by-step explanation:
First of all, lets cut the shape into two. A rectangle and a triangle. This will help us find the slanted side of the shape.
We will use the pythagorean theorem to find the length of the slanted line.
The pythagorean theorem is [tex]a^{2} +b^{2} =c^{2}[/tex].
Input the given information of the triangle lengths that we know; that is the length= 6 and the base=3.
[tex]c= \sqrt{a^{2}+b^{2} } =\sqrt{6^{2}+\ 3^{2} } = 6.7082[/tex]
Now, we round.
6.7082≈ 6.7
We have found the length of the slanted line of the shape.
Now, let's add all the lengths together.
8+6+6.7+11= 31.7
Now, lets round.
31.7 ≈ 32cm

Step-by-step explanation:
Bridgette has 25 pairs of black socks, 15 pairs of white socks, and 20 pairs of colorful socks. What is the ratio of colorful socks to total socks?
help?!
could you please explain to?!
Answers
Answer:
Step-by-step explanation:
So the total # of socks is 25 + 15+ 20, which equals 60.
theres ONLY 20 socks that are colorful, meaning that 20/60 are coloful.
20/60 simplified is 2/6, simply that even further its 1/3, 1/3 is a ration within itself. itll be 1:3
Answer:
1:3 (20:60)
Step-by-step explanation:
So the ratio of colorful socks to total socks is 20:60
This is how:
First write the number of colorful socks which is 20.
From the calculate the total number of socks( 20 + 25 + 15 = 60) which is 60.
Then put a colon and write 60
You need to write the number of colorful socks because that is what was mentioned first then the total number of socks because it was mentioned after the number of colorful socks.
So you can reduce 20:60 to its lowest term.
You write 20: 60 as a fraction [tex]\frac{20}{60}[/tex]
Then reduce [tex]\frac{20}{60}[/tex] to its lowest term which is [tex]\frac{1}{3}[/tex].
Then write [tex]\frac{1}{3}[/tex] as a ratio which is 1:3

Answers
I am doing this problem assuming that you mean to solve for m and n as x and y do not exist in this system of equations.
-4m+2n=6
-4m+n=8
We can see that the coefficient of x for both equations are -4; therefore, elimination with subtraction is possible.
First equation - second equation
n=-2
Then substitude back in to solve for m
-4m+(-2)=8
4m=10
m=5/2
Therefore the answer is
n= - 2
m= 5/2

What is the value of x in the equation 8x – 2y = 48, when y = 4?.
Answers
Step-by-step explanation:
Substitute the value of y into the equation;
[tex]8x-2(4)=48[/tex]
Find the value of x.
Multiply;
[tex]8x-8=48[/tex]
Add 8 to each side;
[tex]8x=56[/tex]
Divide each side by 8;
[tex]x=7[/tex]
Answer:
x = 7
Step-by-step explanation:
Given:
y = 4Step-1: Substitute the y-variable in the equation (8x – 2y = 48)
⇒ 8x - 2y = 48⇒ 8x - 2(4) = 48Step-2: Simplify the L.H.S
⇒ 8x - 2(4) = 48⇒ 8x - 8 = 48Step-3: Add 8 both sides
⇒ 8x - 8 = 48⇒ 8x - 8 + 8 = 48 + 8⇒ 8x = 56Step-4: Divide 8 both sides
⇒ 8x = 56⇒ 8x/8 = 56/8⇒ x = 7In 5 days, Nicole ran a total of 10 miles. She ran the same amount each day. How much did she run each day?

Answer:

b. $53
explanation:
make equations from given information.
consider each minute as "n"equation 1 from plan A :
20 + 0.11(n)
equation 2 from plan B :
14 + 0.13(n)
Solve them simultaneously,
14 + 0.13(n) = 20 + 0.11(n)
0.13(n) - 0.11(n) = 20 - 14
0.02(n) = 6
n = 300
insert n = 300 in any of the equation, to find cost.
14 + 0.13(n)

Explain how you would go about graphing this equation? What would be your first step and how would you go from there? Y=4x+6 *
Answers
Step-by-step explanation:
First I would look at the y intercept. In a linear equation, y = mx + b, b is the y-intercept and m is the slope. This means that (0,6) is a point on the line since at a y-intercept, the x value is 0. First you should plot this point.
Next, the slope is 4, meaning that for every 1 unit to the right, the line rises 4 units. You can count 1 to the right and 4 up from the y-intercept, which gives you (1,10), a second point on the line. After this, you can connect the two points and there you go, you have a graph!

Percy paid $24. 10 for a basketball. The price of the basketball was $22. 99. What was the sales tax rate?.
Answers
Answer:
$3.11
Step-by-step explanation:
you have to subtract 24.10 from 22.99
Answer:
First let's find the increase of the original price to it's new price;
24.10 - 22.99 = 1.11, there was a $1.11 increase.
Though, we need to find the percentage, using the formula:-
Changed price 100
____________ x _____ (100%)
Original amount 1
Our changed price was 1.11, and our original price was 22.99.
1.11 100
_____ x _____ = 4.828 which rounds to 4.83%
22.99 1

The given circle having two external tangents, according to circle
theorem, have the following values;
r = 3m∠1 = 82°m∠2 = 49°x = 82°How can the radial length and angles be found?r² + 1.6² = (0.4 + r)²
(0.4 + r)² - (r² + 1.6²) = 0
0.8·r - 2.4 = 0
0.8·r = 2.4
r = 2.4 ÷ 0.8 = 3
r = 3y = 49°
From the two tangent angle theorem, we have;
m∠1 = ((82 + 98 + 82) - (360 - ((82 + 98 + 82)))) ÷ 2 = 82
m∠1 = 82°According to circle theorems, angle at the center is twice angle

John and 2 friends are going out for pizza for lunch. They split one pizza and 3 large drinks. The pizza cost $12.50. They spend a total of $16.85. Write an equation to represent the problem. Find the cost of one large drink.
Answers
Answer:
Hm, okay.
Step-by-step explanation:
So, if the pizza cost $12.50, and the total money spent is $16.85, we must first subtract our money spent on pizza from the total amount spent.
$16.85 - $12.50 = $4.35
So, that means that John and his two friends spent $4.35 on 3 large drinks. But how do we figure out how much each individual drink cost?
We divide $4.35 by 3.
$4.35 / 3 = $1.45.
So, the amount of money spent on one large drink was $1.45.

Answers
Answer:
2.05 inches
Step-by-step explanation:
V = 4/3 x πr³
36=4πr³/3
36x3= 4πr³
108= 4πr³
108/4 = πr³
27= πr^3
27/π =r³
r=
[tex] \sqrt[3]{27 \div \pi} [/tex]
r= 2.048in
round off to 2.05in
PROOF
V = 4÷3 x πr³
V= 4/3 x π(2.05)³
V=4/3 x π8.6
V=4×π×8.6/3
V=108/3
V=36in³
Therefore: radius= 2.05 inches
