Answer:
the percent change in the amount the group raised is 10%.
Step-by-step explanation:
% change = (new value - old value) old value x 100 = (1,045 - 950)/950 x 100 = 95/950 x 100 = 0.1 x 100 = 10%
Consider this equation.
7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)
Mia solved the equation and determined that m = 2. Is she correct?
Answer:
No, Mia is not correct, the answer is -2.
Step-by-step explanation:
First we are going to use the distributive Property.
Step 1: 2(0.75+0.4). multiply the 2 out. .75m x 2=1.5m and 2 x .4= .8.
We get 1.5m+.8, so 2(0.75+0.4)=1.5m+.8
Now we are going to distribute on the oher side. 4(.5m-.8)
4x .5m=2m and 4x.8=3.2. Keep the sign the same and we get 2m-3.2, so 4(.5m-.8)=2m-3.2
We put this into the new equation to get 1.5m+.8+7.8=-6.4m+2m-3.2
Step 2: combine like terms
.8+7.8= 8.6 and -6.4m +2m =-4.4m
Plug that into our equation and we get 1.5mn+8.6=-4.4m-3.2
Step 3: Switch the sides
Bring -4.4m to the other side to get 1.5m+4.4m=5.9m
One side is 5.9m
We bring 8.6 to the other side to get -8.6. now we do -3.2-8.6=-11.8.
Our new equation is 5.9m=-11.8
divide by 5.9 on both sides to get our answer of
m=-2

Naomi buys an antique dresser for $1200. Each year, it appreciates (increases in value) by 3.5%. Write an equation to determine its value V(n) after n number of years
9514 1404 393
Answer:
V(n) = 1200·1.035^n
Step-by-step explanation:
The value multiplies by 1+3.5% = 1.035 each year. After n years, that growth factor has been applied n times, so the value is ...
V(n) = 1200·1.035^n

6. When Landon saves $15 more, he will have enough money to buy a basic MP3 player. The player he wants to buy costs $199, which is 4 times the cost of the basic player. Which equation could be used to determine n, the number of dollars Landon has already saved?
A. 4n +15 = 199 B. 4(n+15) = 199 C. n + 4(15) = 199
Answer:
A) 4n+15=199
Because n is the cost of the basic player, so 4*n would be the cost of the player he wants. Also +15 since he needs 15 more dollars.

Which of the following equations is equivalent to ab − 8 = 3b, when solving for b .
a = 11
b = 8/2a
b = -8/3 - a
b = -8/a - 3
The equivalent equation for the given equation is b=8/(a-3).
What is an equivalent equation?Algebraic equations with equivalent solutions or roots are called equivalent equations. An analogous equation is one that is created by adding or removing the identical quantity or expression from both sides of a given equation. An equation is equivalent if both sides are multiplied or divided by the same non-zero value.
The given equation is ab-8=3b.
Now, transpose 3b to other sides of an equation, we get
ab-3b=8
b(a-3)=8
b=8/(a-3)
Therefore, the equivalent equation for the given equation is b=8/(a-3).

Carla makes a scale drawing of her garden that is 30 feet long and 24 feet wide. If the garden in her drawing is 20 inches long, what is its width, in inches?
Answer:
16 in.
Step-by-step explanation:
Notice that 20*1.5 = 30
Use this ratio for 24 except reverse.
16*1.5 = 24
Hope this helps! Have a nice day!
Answer:
16
Step-by-step explanation:
Real length: 30 ft
Drawing length: 20 in.
Real width: 24 ft
Drawing width: x
30/20 = 24/x
3/2 = 24/x
1/2 = 8/x
x = 2 * 8

Jane is helping the librarian stack books on some new shelves. She is to stack 116 books on 16 shelves. The librarian told her to put the same number of books on each of the 16 shelves.
Describe one way that Jane can use to determine the number of books she should put on each shelf.
Answer:
She should divide The total of books to the total of shelfs
Step-by-step explanation:
Answer:
she can put 7 on each shelf with 4 left over.
Step-by-step explanation:
You divide 116 by 16, which is 7.25 and 1/4 of 16 is 4. So you know you have 4 leftover.

14 points if you can answer this
Answer:
-2
Step-by-step explanation:
you do -4+-6+2+6
First, we must determine slope using the given points and pluging them in the slope formula*.
[tex]m = \frac{6 - (-6)}{2 - (-4)} = \frac{12}{6} = 2[/tex]
The slope is 2. You can prove this by using the graph.
Second, we plug in the slope we found, and one of the given points to solve for b using slope-intercept form**.
[tex]6 = 2(2) + b\\\\6 = 4 + b\\\\2 = b[/tex]
The y-intercept (or b) is 2. You can prove this by using the graph.
Finally, we can now create the equation of the line in slope-intercept form.
[tex]y = 2x + 3[/tex]
*Slope formula: y₂ - y₁/x₂ - x₁
**Slope-intercept form: y = mx + b
