If 13 candy bars cost $19.76, how much do 20 candy bars cost?
Answer:
$30.40
Step-by-step explanation:
to find out how much 20 candy bars would cost, first, we have to find out how much 1 candy bar costs. we do this by dividing $19.76 by 13.
$19.76 ÷ 13 = $1.52
so now we know that one candy bar costs $1.52. now, we multiply this value to 20, to know how much 20 candy bars cost. therefore, we get:
20 × $1.52 = $30.40

The speed of a fish before jumping out of the water can be represented by the equation s = 3h, where h
represents the height, in centimeters, the fish jumps out of the water and s represents the speed of the fish in
meters per second. If the fish is swimming at 15 meters per second before jumping out of the water, how high
can the fish jump?
Answer: The fish can jump 5m high.
Step-by-step explanation:
Given that
s = 3h
where
h = the height(cm) the fish jumps out of the water
and s = speed of the fish(meters per second) then
3 must have seconds as its unit.
Now, If the fish is swimming at 15 meters per second
Then the fish can jump =
s= 3h
15m/s =3h
h= 15m/s/3s
h= 5 meters

how do you know that the expression 2x + 4y is not equivalent to 6xy
Answer:
The expression is not equivalent because you cannot combine 2 variables that are different from eachother.
Step-by-step explanation:
you are able to add 2+4 but because they have variables with them, x and y, you can not add them together.
Determine whether the sequence is geometric. If so, find the common ratio. 3.0, 6.0, 12.0, 24.0
Answer:
The sequence is geometric and the common ratio is 2
Step-by-step explanation:
A sequence is geometric if each term (after the first one) is equal to the term before it times some constant number, called the 'common ratio'.
Examples: 1, 2, 4, 8, 16, ... has a common ratio of 2 because 2*2 = 4, and 4*2 = 8, and so on.
Also, --> 4, 2, 1, 1/2, 1/4/ 1/8, ... has a common ratio of 1/2 because
4 * 1/2 = the next term 2, and 2 * 1/2 = the next trem 1/4, and son on.
In this case, 3 * 2 = 6
6 * 2 = 12
12 * 2 = 24
The sequence is geometric and the common ratio is 2

What is the slope of the line shown in the graph?
A. -3/2
B. -1/2
C. 3/2
Answer:
-3/2
Step-by-step explanation:
Answer:
The slope of the line shown is -3/2.
Step-by-step explanation:
You can find this by using the rise/run method between the two points.
Between the two points, the line falls 3 units down (this is the rise part) and goes 2 units to the right (this is the run part). Since the line falls 3 units down between the two points, this number would be -3, and since it runs to the right by two units, the slope can be identified as -3/2.

The area of a floor in square yards is one-ninth the area of the floor in square feet. Write an equation representing y, the area in square yards, to f, the area in square feet.
HELP ME
Answer:
y = f/9
Step-by-step explanation:
Area of a floor in square yards = y = f/9
Area of a floor in square feet = f
The number that represents the area of the floor in square feet is 9 times the number representing the area in square yards. This makes sense because the ratio of yard to feet is 1 : 3 and the ratio of square yard to square feet is the same ratio but squared so 1 : 9.
If y represents the area in square yards and f the area in square feet.
y = f/9
Emily the blacksmith blends one alloy of silver that is 45% silver and another that is 95% silver. To the nearest ton, how much of each alloy is needed to make 139 tons of a 70% silver alloy?
please answer
Answer:
69.5 tons of Alloy 1 (of 45% silver) and 69.5 tons of Alloy 2 (of 95% silver) is needed to make 139 tons of 75% silver alloy
Step-by-step explanation:
Given
[tex]Alloy\ 1 = 45\%[/tex]
[tex]Alloy\ 2 = 95\%[/tex]
Required
How much of each alloy is needed for 70% silver alloy 139 tons
Let the amount of alloy 1 needed be x and the amount of 2 needed by y.
So:
[tex]x + y = 139[/tex]
Make y the subject
[tex]y = 139 - x[/tex]
The percentage of each needed is represented as:
[tex]45\% * x + 95\% * y = 139[/tex]
[tex]45\% * x + 95\% * y = 70\% * 139[/tex]
[tex]0.45x + 0.95y = 0.70 * 139[/tex]
[tex]0.45x + 0.95y = 97.3[/tex]
Substitute 139 - x for y in the above equations
[tex]0.45x + 0.95*(139-x) = 97.3[/tex]
[tex]0.45x + 0.95*139-0.95*x = 97.3[/tex]
[tex]0.45x + 132.05-0.95x = 97.3[/tex]
Collect Like Terms
[tex]0.45x -0.95x = 97.3-132.05[/tex]
[tex]-0.50x = -34.75[/tex]
Make x the subject
[tex]x = \frac{-34.75}{-0.50}[/tex]
[tex]x = 69.5[/tex]
Recall that:
[tex]y = 139 - x[/tex]
[tex]y = 139 - 69.5[/tex]
[tex]y = 69.5[/tex]
This implies that:
69.5 tons of Alloy 1 (of 45% silver) and 69.5 tons of Alloy 2 (of 95% silver) is needed to make 139 tons of 75% silver alloy
