4x3=12
It says Find out the value of x
Answer:
x=31, x=31, x=21.
Step-by-step explanation:
So for number 33, we see that 2x+28=90 degrees so you just simplify the equation to 2x=62, x=31.
For number 34, we see that 4x+56=180 (flat line), so we simplify the equation again and get 4x=124, x=31 degrees.
For number 35, according to the vertical angle theorem, 43=2x+1, so we simplify that too and we get 42=2x, 21=x, x=21.
1) Which line on the graph below has a slope of 4/3? *
Answer:
line b
Step-by-step explanation:
go up 4 and over 3 on line b
ANSWER FAST....!!!!!!!!!!!
Should be 10 because each time you multiply 10 in the graph, you can see how it goes up by 10
solve the equation
48= y + 5y
48=y+5y
pretend that there is a 1 in front for the y
48=1y+5y
add the like terms first
1y+5y=6y
48=6y
divide both sides by 6 to get y by itself
48/6=6y/6
8=y
answer:
y=8
Answer:
y = 8
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
48 = y + 5y
Step 2: Solve for y
Combine like terms: 48 = 6yDivide 6 on both sides: 8 = yRewrite: y = 8Step 3: Check
Plug in y into the original equation to verify it is a solution.
Substitute in y: 48 = 8 + 5(8)Multiply: 48 = 8 + 40Add: 48 = 48Here we see that 48 does indeed equal 48.
∴ y = 8 is a solution of the equation.
What is an equation of the line that passes through the point (4,-3) and is perpendicular to the line x-2y=2?
Answer: 2x+y+11=0
Step-by-step explanation:
The equation of given line is x-2y-2=0
Slope of given line is (m1)= - coefficient of x÷coefficient of y
m1= -1÷-2 =1÷2
Let slope of required line be m2.
Since the two lines are perpendicular,
So,
m1×m2= -1
or, 1÷2×m2 = -1
m2 = -2
The required line is passing through (4,-3)
Using two points slope form,
y-y1 = m(x-x1)
or, y-(-3)= -2(x+4)
or, y+3= -2x -8
or, 2x+y+3+8 = 0
2x+y+11 = 0 which is required equation of line.
• When volleyballs are purchased, they are not fully inflated. A partially inflated
volleyball can be modeled by a sphere whose volume is approximately 180 in). After
being fully inflated, its volume is approximately 294 in. To the nearest tenth of an
inch, how much does the radius increase when the volleyball is fully inflated?
Answer:
The radius increase when the volleyball is fully inflated is 0.5
Step-by-step explanation:
Volume of Partially inflated volleyball = 180 in³
Volume of Full inflated volleyball = 294 in³
We need to find how much does the radius increase when the volleyball is fully inflated?
First we will find the radius of both Partially inflated and Full inflated volleyball. Then we will find increase in radius.
The formula for Volume of sphere is: [tex]Volume=\frac{4}{3}\pi r^3[/tex]
Finding Radius of Partially inflated volleyball
Volume = 180
Putting values and finding radius of Partially inflated volleyball
[tex]Volume=\frac{4}{3}\pi r^3\\180=\frac{4}{3}*3.14*r^3\\4.186r^3=180\\r^3=\frac{180}{4.186}\\r^3=43.0\\Taking\:cube\:root\:on\:both\:sides\\\sqrt[3]{r^3}=\sqrt[3]{47}\\r= 3.6[/tex]
So, radius of Partially inflated volleyball is r = 3.6
Finding Radius of Fully inflated volleyball
Volume = 294
Putting values and finding radius of Fully inflated volleyball
[tex]Volume=\frac{4}{3}\pi r^3\\294=\frac{4}{3}*3.14*r^3\\4.186\:r^3=294\\r^3=\frac{294}{4.186}\\r^3=70.23\\Taking\:cube\:root\:on\:both\:sides\\\sqrt[3]{r^3}=\sqrt[3]{70.23}\\r= 4.1[/tex]
So, radius of Partially inflated volleyball is r = 4.1
Now, finding increase in radius by subtracting radius of fully inflated volleyball with partially inflated volleyball
Increase in radius of Fully inflated volleyball = 4.1 - 3.6
Increase in radius of Fully inflated volleyball = 0.5
So, the radius increase when the volleyball is fully inflated is 0.5

Answer:
The better deal is 8 for $7.50
4 of pack one=$25
2 of pack two=$15
Spent altogether= $40
Answer:
Which is the better deal? Pack of 8 is a better deal.
Buy 4 of Pack One: $24.40
Buy 2 of Pack Two: $11.90
How much did you spend altogether? $36.30
Step-by-step explanation:
Let's start with the Swag Bags. To figure out if something is a good price, divide the items inside of it by the price so you can get the $ per item and compare.
[tex]\frac{6.25}{6}[/tex] = $1.04 per item for Pack of 6
[tex]\frac{7.50}{8}[/tex] = $.94 per item for Pack of 8
Generally, saying "which item is the better deal" refers to which price per item is cheaper. In this case, Pack of 8 is a better deal.
Now, goodie bags.
Pack one costs $6.10 while Pack two costs $5.95.
"Buy 4 of Pack One: $" is asking for the price of 4 Pack Ones. To do this, you simply multiply the pack one price by 4, since you are buying 4 of them.
4 * 6.10 = $24.40
Same idea for Pack Two, just different price and different amount.
2 * 5.95 = $11.90
How much did you spend altogether? Add the total values for both goodie bag packs.
$24.40 + $11.90 = $36.30

Answer:
m∠1 = 148° and m∠2 = 32°
Step-by-step explanation:
m∠1 + m∠2 = 180° (supplementary angles)
4x° + (x - 5)° = 180 (substitution)
4x + x - 5 = 180
5x - 5 = 180
5x = 185
x = 37
m∠1 = 4(37)° =148° and m∠2 = (37 - 5)° = 32°

A bucket contains 50 lottery balls numbered 1-50. One is drawn at random. Find each probability.
1. p(multiple of 6 | 2 digit number)
2. p(at least 20 | prime number)
Please only answer if you know it.
Answer:
1. 7/41
2. 7/15
Step-by-step explanation:
1. Probability that it is a multiple of 6 given that it is a 2 digit number: There are 7 numbers that are a multiple of 6 and are 2 digits: 12, 18, 24, 30, 36, 42, and 48. There are 41 numbers that are 2 digits. So, it is 7/41
2. Probability that it is at least 20 given that it is prime. Out of the prime numbers from 1-50, 7 of them are at least 20 and there are 15 primes in that range in total. So, it is 7/15

form
Answer:
2/12 :) or even 1/6 if you simplify
Step-by-step explanation:
Answer:
2/12
Step-by-step explanation:
1 dice = 1/6 × 2 because we have to die but this is different from normal multiplication you do the probability of finding 2 in both which is 1+1 over the total number which is 6+6. Therefore your answer would be 2/12

Answer:
The measure of <TRU is 72 deg.
Step-by-step explanation:
<QRU is a right angle, so it measures 90 deg.
Since m<QRT = 18 deg, then m<TRU must be 72 deg since 72 + 18 = 90.
Answer: The measure of <TRU is 72 deg.
Instructions: Find the missing side lengths. Leave your answers as radicals in simplest form.

Which of the points below does not lie on the curve y=x^2
Options:
[tex]A.\ (\frac{3}{2}, \frac{9}{2})[/tex]
[tex]B.\ (-1, 1)[/tex]
[tex]C.\ (4, 16)[/tex]
[tex]D.\ (\frac{1}{2}, \frac{1}{4})[/tex]
Answer:
[tex]A.\ (\frac{3}{2}, \frac{9}{2})[/tex]
Step-by-step explanation:
Given
[tex]y = x^2[/tex]
Required
Determine which of the given points is not true
[tex]A.\ (\frac{3}{2}, \frac{9}{2})[/tex]
Here
[tex]x = \frac{3}{2}[/tex] and [tex]y = \frac{9}{2}[/tex]
Substitute these values in [tex]y = x^2[/tex]
[tex]\frac{9}{2} = (\frac{3}{2})^2[/tex]
[tex]\frac{9}{2} = \frac{3}{2}*\frac{3}{2}[/tex]
[tex]\frac{9}{2} \ne \frac{9}{4}[/tex]
Both sides of the equation are not equal. Hence, this point do not line on the curve
[tex]B.\ (-1, 1)[/tex]
Here
[tex]x = -1[/tex] and [tex]y = 1[/tex]
Substitute these values in [tex]y = x^2[/tex]
[tex]1 = (-1)^2[/tex]
[tex]1=1[/tex]
Both sides of the equation are equal. Hence, this point line on the curve
[tex]C.\ (4, 16)[/tex]
Here
[tex]x = 4[/tex] and [tex]y = 16[/tex]
Substitute these values in [tex]y = x^2[/tex]
[tex]16 = 4^2[/tex]
[tex]16 = 16[/tex]
Both sides of the equation are equal. Hence, this point line on the curve
[tex]D.\ (\frac{1}{2}, \frac{1}{4})[/tex]
Here
[tex]x = \frac{1}{2}[/tex] and [tex]y = \frac{1}{4}[/tex]
Substitute these values in [tex]y = x^2[/tex]
[tex]\frac{1}{4} = (\frac{1}{2})^2[/tex]
[tex]\frac{1}{4} = \frac{1}{2}*\frac{1}{2}[/tex]
[tex]\frac{1}{4} = \frac{1}{4}[/tex]
Both sides of the equation are equal. Hence, this point line on the curve
From the calculations above; only [tex]A.\ (\frac{3}{2}, \frac{9}{2})[/tex] do no lie on the curve
