Jessica makes $1500 a month at her job. If she saves 20% of it each month, how much savings will she have after one year? Remember that there are 12 months in one year!
$3,600
Step-by-step explanation:
You'd multiply 1,500 with .20 which equals 300. You'd then multiply 300 and 12 together to make $3,600.
What is the coefficient of m in the sum of (23m−34)( 3 2 m− 4 3 ) and (−16m−r)(− 6 1 m−r) ?
Answer:
77r - 2077
Step-by-step explanation:
To find the the sum of (23m−34)( 3 2 m− 4 3 ) and (−16m−r)(− 6 1 m−r)
First open the bracket
23m × 32m - 23m × 43 - 34 × 32m + 34 × 43
736m^2 - 989m - 1088m + 1462
736m^2 - 2077m + 1462
Open the second bracket
16m × 61m + 16m × r + r × 61m + r × r
976m^2 + 16mr + 61mr + r^2
976m^2 + 77mr + r^2
Adding both equations together
736m^2 - 2077m + 1462 + 976m^2 + 77mr + r^2
1712m^2 + 77mr - 2077m + 1462 + r^2
1712m^2 + m( 77r - 2077 ) + 1462 + r^2
Therefore The coefficient of m is 77r - 2077
what is the value of B and C?
Step-by-step explanation:
value of b is 73 (reason : sum of triangles)
a= 34 ( reason:180-73-73=34)
Answer: 73+73=146, 180-146= 34°
Step-by-step explanation:
b is parallel to 73, b= 73°
c = 34°
consider the equation x^2-7x-8=0 and describe it's roots
Answer:
there are two different, real roots.
Step-by-step explanation:
The coefficients of this quadratic are {1, -7, -8}. Let's find the discriminant, b^2 - 4ac. In this case a = 1, b = -7 and c = -8 and so the discriminant value is
(-7)^2 - 4(1)(-8), or 49 + 32, or 81.
Because the discriminant is positive, we know immediately that there are two different, real roots.
We are not asked to find the roots, but let's do it anyway:
-(-7) ± √81
x = ------------------ => x = 8 and x = -2 (which are real and different from
2 one another).

Out of 15,000 voters in a constituency, 60% voted. Find the percentage of voters who did not vote. Can you now find how many actually did not vote?
Answer:
40 did not vote
6000 people did not vote
Step-by-step explanation:
1 % of 15,000 = 150
150 * 40 = 40% of 15,000 = 6000

f(x)=2x^2+9x+4
what are the zeros
Answer:
(2x+1) (x+4)
Explanation:
The idea is to break down the middle term into two monomials which can be used in the factorization process. Note that
2.4=8=8.1 , and that we may write 9=8+1 , which may help us in the process.
Let us write:
2x^2+9x+4
=2x^2+8x+x+4
=2x(x+4)+(+4)
=(2x+1)(x+4)

Step-by-step explanation:
Are the graphs of y = -2x + 4 and y = (1/4)x -2 parallel, perpendicular, or neither? *
Answer: Neither
Step-by-step explanation:
For this to be paralell it would need to have the same slope. (They don't have the same.) For this to perpandicular it would have to reciporcal ( Ex: -2 reciporcal would -1/2 or 1/4 reciprocal would have to be 4)
Answer:
neither
Step-by-step explanation:
For two lines to be parallel, their slopes must be equal.
For two lines to be perpendicular, their slopes must have a product of -1. (The only exception is a vertical line and a horizontal line which are perpendicular, but the product of their slopes is not -1.)
When the equation of a line is written in the slope-intercept form,
y = mx + b,
m is the slope.
y = -2x + 4 has a slope of -2.
y = (1/4)x -2 has a slope of 1/4.
Clearly, -2 and 1/4 are not equal, so the lines are not parallel.
Now we find the product of the slopes.
(-2) * (1/4) = -2/4 = -1/2
The product of the slopes does not equal -1, so the lines are not perpendicular.
Answer: neither

Janice NEEDS 3 GALLONS of lemonade for a party. She has 4 quarts, 6 pints and 4 cups of lemonade already made. How many CUPS of lemonade does Janice have? Be sure to re-state the question when giving your answer.
Answer:
32 cups
Step-by-step explanation:
To find the total number of cups, we have to convert the measures that are not in cups to cups and add
1 quart = 4 cups
4 quarts = 4 x4 = 16 cups
1 pint = 2 cups
6 pints = 2 x 6 = 12 pints
total number of cups = 16 + 12 + 4 = 32 cups
Which equation shows the commutative property of addition?
A) 4 + -4 = 4+ -4
B) x(4 + 4) = 4 (x +4)
C) 4 + 2 + 3 = 3 + 2 +4
D) 4 +2 = 6
Answer:
C

When you flip a biased coin the probability of getting a tail is 0.2.
How many times would you expect to get tails if you flip the coin 240 times?
Answer:
48
Step-by-step explanation:
Multiply 0.2 × 240 = 48.
It's a very biased coin, so the outcome will be considerably less than the 120 we would expect from a fair coin.
find the value of X, please!
Answer:
x=42°
Step-by-step explanation:
We know that 2 of the legs are congruent, so the angles opposite them will be congruent.
The angles of a triangle add up to 180°
This can be represented by [tex]96+2x=180[/tex]
[tex]2x=84[/tex]
[tex]x=42[/tex]
Hope this helps :-)
Answer: 42 degrees
Step-by-step explanation: Since this is an isosceles triangle, your remaining two angles will be equal
There are 180 degrees in any triangle
Since you have already used 96 degrees, you must subtract to find what is remaining
180-96=84
Since your remaining two angles are equal, you can half 84 to find your answer
84/2=42
Both x and your one remaining angle should be 42
X=42

Kiran is playing a video game. He earns 3 stars for each easy level he completes and 5 stars for each difficult level he completes. He completes more than 20 levels total and earns 80 or more stars
Answer:
10 easy levels and 10 difficult levels
Step-by-step explanation:
Given data
let the number of easy levels be x
and the number of difficult levels be y
so
x+y= 20----------1
and
3x+5y= 80------2
from 1
x=20-y
put this in 2
3(20-y)+5y= 80
60-3y+5y=80
2y=80-60
2y=20
y= 20/2
y= 10
put y= 10 in 1
x+10=20
x=20-10
x= 10
Hence Kiran played 10 easy levels and 10 difficult levels
Alicia wants to cover a footrest in the shape of a rectangular prism with cotton fabric. The footrest is 14 inches by 11 inches by 13 inches. She has 1 square yard of fabric. Can she completly cover the footrest
Answer:
Since the footrest measures 1.54 square yards, Alice will not be able to cover it completely.
Step-by-step explanation:
Since Alicia wants to cover a footrest in the shape of a rectangular prism with cotton fabric, and the footrest is 14 inches by 11 inches by 13 inches while she has 1 square yard of fabric, to determine if she can she completly cover the footrest the following calculation must be performed:
1 square yard = 1296 square inches
14 x 11 x 13 = X
154 x 13 = X
2.002 = X
2.002 / 1.296 = 1.54
Thus, since the footrest measures 1.54 square yards, Alice will not be able to cover it completely.
