You buy 80 stamps for 17 dollars some stamps were 15 cents each and the others were 25 cents each. how many of each kind did you buy
Answer:
30 of the 15 cent stamps and 50 of the 25 cent stamps
Step-by-step explanation:
Create a system of equations, where x is the number of 15 cent stamps and y is the number of 25 cent stamps:
x + y = 80
0.15x + 0.25y = 17
Solve by substitution by rearranging the first equation:
x + y = 80
x = 80 - y
Substitute 80 - y as x into the second equation:
0.15x + 0.25y = 17
0.15(80 - y) + 0.25y = 17
12 - 0.15y + 0.25y = 17
12 + 0.1y = 17
Solve for y:
0.1y = 5
y = 50
Plug in 50 as y into the first equation, and solve for x:
x + y = 80
x + 50 = 80
x = 30
So, you bought 30 of the 15 cent stamps and 50 of the 25 cent stamps
answer: ten 15¢ stamps and forty 20¢ stamps.

f(x) = 2x+3 and g(x) = x - 7. Find f(-2)+g(4)
f(-2) = 2(-2)+3
f(-2) = -4+3
f(-2) = -1
g(4) = (4) - 7
g(4) = -3
f(-2) + g(4) is -1 + (-3) which is -4
I need the answer to this please help.
Answer:
see below
Step-by-step explanation:
sin x = cos x
opp/ hyp = adj /hyp
Multiply each side by the hypotenuse
opp = adj
The opposite side must equal the adjacent
Since this is a right triangle
opp ^2 + adj ^2 = hypotenuse^2
opp ^2 + opp ^2 = hypotenuse^2
2 opp ^2 = hypotenuse^2
Take the square root of each side
sqrt(2 opp ^2) =sqrt( hypotenuse^2)
sqrt(2) opp = hyp
We know sin X = opp / hyp
sin x = opp / (sqrt(2) / hyp)
sin x = 1 / sqrt(2)
sin x = sqrt(2) /2
Taking the inverse sin of each side
x = sin ^-1 ( sqrt(2) /2)
anybody know the answer if so can you please provide the step by step so i can understand it
Answer:
35,000 feet
Step-by-step explanation:
So t is the atmospheric temperature
g is the ground temperature
First sub in the values that you know
t = -65.5 and g = 57
-65.5 = -0.0035a + 57
Rearrange: to make 'a' on its own
-65.5 - 57 = -0.0035a
-122.5/-0.0035 = a
Use a calculator
a = 35,000 ft
Mr. Gatti is looking to buy some apples to bake a fresh & tasty apple pie. He goes to the store and sees two deals that are going on for apples: Deal A - 3/4 of a pound for $2.50 Deal B - LaTeX: 2\frac{2}{10}2 2 10 pounds for $5.25 1. Which is the better deal, and why? Explain your answer. Put your answer in $ per pound format
Answer:
Deal A is best
Step-by-step explanation:
Given
Deal A:
3/4 lb for $2.50
Deal B:
2/10 lb for $5.25
Required
Which deal is the better
To do this, we simply calculate the lb/dollar ratio
i.e.
[tex]Ratio = \frac{Amount}{Size}[/tex]
For Deal A:
[tex]Ratio = \$2.50/\frac{3}{4}lb[/tex]
[tex]Ratio = \$2.50 * \frac{4}{3}lb[/tex]
[tex]Ratio = \frac{\$10}{3}lb[/tex]
[tex]Ratio = \$3.33/lb[/tex]
For Deal B:
[tex]Ratio = \$5.25/\frac{2}{10}lb[/tex]
[tex]Ratio = \$5.25 * \frac{10}{2}lb[/tex]
[tex]Ratio = \frac{52.5}{2}lb[/tex]
[tex]Ratio = \$26.25/lb[/tex]
The better deal is the least expensive:
Hence: Deal A is better

The graph of a linear function is shown on the coordinate grid below.
What are the slope and y-intercept of the linear function shown in the grid?
A) Slope = –0.4, y-intercept = –5
B) Slope = 2.5, y-intercept = –5
C) Slope = –2.5, y-intercept = 2
D) Slope = 0.4, y-intercept = 2
Answer:
B) Slope = 2.5, y-intercept = –5
Step-by-step explanation:
Given the following points on the grid, (-1.5, -8.75) and (3.5, 3.75), the slope can be calculated as follows using the formula, [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let,
[tex] (-1.5, -8.75) = (x_1, y_1) [/tex]
[tex] (3.5, 3.75) = (x_2, y_2) [/tex]
[tex] m = \frac{3.75 -(-8.75)}{3.5 -(-1.5)} [/tex]
[tex] m = \frac{3.75 + 8.75}{3.5 + 1.5} [/tex]
[tex] m = \frac{12.5}{5} [/tex]
[tex] m = 2.5 [/tex]
Slope = 2.5.
The y-intercept is the point at which the line intercepts the y-axis. On the graph, the line intercepts the y-axis at y = -5. Therefore, the y-intercept = -5.

A department store is offering the same percentage discount on all of their shoes Suppose one pair of shoes is marked down from $70 to $49. Based on that percentage discount, what would the new price be for a pair ol
shoes that originally cost $110
Answer:
$77Step-by-step explanation:
Discount is:
$70 - $49 = $21Discount % is:
21/70*100% = 30%Applying same discount to pair of shoes for $110:
$110 - 30% = $110*(100 - 30)/100 = $110*0.7 = $773 x 9+2 x 20+5 x 3.50

5*-9=-45
-45*-2=90
Answer:
90
Step-by-step explanation:
Let's solve this step by step:
(5) · (-9) · (-2)
First, there are two negatives in this equation. They will cancel each other out, to simply make 9 · 2:
5 · 9 · 2 =
Now, we do the multiplication:
5 · 9 · 2 = 45 · 2 = 90
90 is the answer!
Jackrabbits are capable of reaching speeds up to 40 miles per hour. How fast is this in feet per second? Round to the nearest whole number
Answer:
59 feet per second
Step-by-step explanation:
[tex]40 mph = \frac{40*5280feet}{1hour} \\40mph = 211200 feet/per/hour[/tex]
to convert 211200 feet per hour to feet per second, we need to know how many seconds are in one hour
60seconds * 60 minutes = 3600 seconds
[tex]211200/3600 = 58.66666666666.... =59[/tex]
Davos has $150,000 to invest. His intent is to earn 7.5% interest on his investment. Davos will invest part of the money at 5.6% interest and part at 9.7% interest. How much does Paul need to invest in each option to earn a 7.5% return on the $150,000? Round to the nearest dollar.
Answer:
The amount invested on 5.6% interest = $80488
The amount invested on 9.7% interest = $69512
Step-by-step explanation:
Given that total amount of investment = $150,000
Let the amount invested on 5.6% interest = $[tex]x[/tex]
Now, amount invested on 9.7% interest = $(150000-[tex]x[/tex])
Total interest to be earned = 7.5%
Formula to be used:
[tex]Simple\ Interest = \dfrac{P\times r\times t}{100}[/tex]
Where, [tex]P[/tex] is the amount invested
[tex]r[/tex] is the rate of interest
[tex]t[/tex] is the time for which amount is invested.
As per question statement:
[tex]\dfrac{x\times 5.6}{100}+\dfrac{(150000-x)\times 9.7}{100}=\dfrac{150000\times 7.5}{100}\\\Rightarrow 5.6x-9.7x=150000(7.5-9.7)\\\Rightarrow 4.1x=150000\times 2.2\\\Rightarrow x = \dfrac{330000}{4.1}\\\Rightarrow x \approx \bold{\$80488}[/tex]
The amount invested on 5.6% interest = $80488
The amount invested on 9.7% interest = $150000 - $80488 = $69512
What is the solution: –3(3x –2) = –30
Answer:
x=4
Step-by-step explanation:
–3(3x –2) = –30
Divide each side by -3
–3(3x –2)/-3 = –30/-3
3x –2 = 10
Add 2 to each side
3x –2+2 = 10+2
3x = 12
Divide each side by 3
3x/3 = 12/3
x = 4
Answer:
X = 4
Step-by-step explanation:
1: Distribute
-3 (3x - 2) = -30 (Multiply 3x and -2 by -3)
-9x + 6 = -30
2: Combine Like Terms
-9x + 6 = -30 (Subtract 6 from -30)
-9x = -36
3: Divide
-9x = -36 (Divide -36 by -9 to get x by itself)
x = -36 / -9
4: Solve
x = -36 / -9
X = 4
