What is f /4 − 24 = −28
Answer: i assume you're looking for F, if so F = -16
Step-by-step explanation:
you would start by adding +24 to each side of the equation, giving you f/4 = -4
then, you would multiply each side of the equation by 4, giving you f = -16

Mario made 2 goals for every 5 shots on goal. What is the probability that Mario would make 2 goals on two shots?
Answer:
16%
Step-by-step explanation:
To calculate this we first need to calculate the probability of Mario scoring for every individual shot that he takes. Since he makes 2 goals for every 5 shots on average, we simply divide these numbers to get the probability of a goal per shot.
2 / 5 = 0.4 ...multiply by 100 to get percentage value
0.40 * 100 = 40%
We see that the probability of scoring a goal per shot is 40%. Now we need to multiply this probability twice to get the probability of scoring 2 consecutive goals in two shots.
0.40 * 0.40 = 0.16 ... multiply by 100 to get percentage value
0.16 * 100 = 16%
Answer:
16%
Step-by-step explanation:
I know that 2/5 = 0.4 or 40%
and 0.4 x 0.4 = 0.16
or 16%
basically what the other one said, without words
what is the prime factor of 350
Answer:
If we put all of it together we have the factors :2 x 5 x 5 x 7 = 350.
Step-by-step explanation:
It can also be written in exponential form as 21 x 52 x 71.
Hope this is helpful .
Answer:
Step-by-step explanation:
draw the prime factor tree of 350
you can choose any 2 numbers that equals 350, then continue in that way by choosing any 2 numbers that equals the number that's on top of the 2 other numbers when multiplying, except 1×number, because it won't help you to get the prime factors of a specific number, unless it's a prime number so you don't need to multiply by any number
350
35 10
5 7 2 5
350=2×5×5×7

Student Council held a bake sale to raise money for the local food pantry. They sold a total of 40 items which included pies and cakes. Pies were $10 each and cakes were $8 each. They raised $356. How many pies and how many cakes did they sell?
Answer: 18 pies, 22 cakes
Step-by-step explanation:
Let the number of pies sold be represented by p.
Let the number of cakes be represented by c.
The information in the question can then be represented in an equation as:
p + c = 40 ........ i
10p + 8c = 356 ....... ii
Multiply equation i by 10
Multiply equation ii by 1
10p + 10c = 400 ....... iii
10p + 8c = 356 ....... iv
Subtract iv from iii
2c = 44
c = 44/2
c = 22
22 cakes were sold
Since 40 items were sold, the number of pies sold will be:
= 40 - 22
= 18 pies

A teacher surveyed her class after they had taken a vocabulary test. Eighteen of the students claimed they had studied at least one hour for the test. The remaining twelve students admitted that they had not studied for the test at all. The test results (expressed as a percent) for the two groups are shown below.
Studied: 88, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 84
Did Not Study: 82, 72, 45, 91, 58, 83, 65, 87, 90, 77, 73, 89
Which of the following statements are true?
There is no mode of the group that studied.
In general, those students that studied scored much higher than those students that did not study.
The mean of the group that studied is over 15 percentage points higher than the mean of the group that did not study.
The median of the group that studied is over 95.
The median of the group that did not study is less than 80.
Answer:
In general, those students that studied scored much higher than those students that did not study.

Answer:
5/8+1/3=6/11
first u add the fraction and u get the answer of 6/11.
Answer:
7/24
Step-by-step explanation:
5/8 = 15/24
1/3 = 8/24
15/24-8/24 = 7/24
The question was what fraction of all the songs are jazz. Therefore you need to find the common denominator which is 24. (8x3 =24).
Next you Multiply 5x3 which equals 15 and then you multiply 1x8 which equals 8. (We do this because you need to multiply your numerator by the same number you multiplied your denominator with)
Finally, you subtract 8/24 from 15/24 which equals 7. (15-8=7 [make sure you keep your denominator 24] )
Therefore your answer is 7/24

Which of these describes the equation –18x + 9y = –416?
A
The equation is not linear because it has 2 variables, not 1.
B
The equation is not linear because it is not in the form y = mx + b.
С
The equation is linear because it has variables with exponents of 0.
D
The equation is linear because it can be rewritten in the form y = mx + b.
Answer:
We conclude the equation is linear because it can be rewritten in the form [tex]y = mx + b[/tex].
Hence, option D is correct.
Step-by-step explanation:
The slope-intercept form of the line or linear equation
[tex]y = mx+b[/tex]
where
[tex]m[/tex] is the slope[tex]b[/tex] is the y-intercept
Important Tip:
The graph of a linear equation is always a straight line.
Convert the given equation in the slope-intercept form
[tex]18x + 9y = -416[/tex]
subtract 18x from both sides
[tex]18x+9y-18x = - 18x-416[/tex]
simplify
[tex]9y = -18x - 416[/tex]
divide both sides by 9
[tex]y=-2x-\frac{416}{9}[/tex]
Now, comparing the equation [tex]y=-2x-\frac{416}{9}[/tex] with a slop-intercept form of linear equation
The slope m = -2The y-intercept b = -416/9Therefore, we conclude the equation is linear because it can be rewritten in the form [tex]y = mx + b[/tex].
From the attached graph, is also clear that the graph of the equation [tex]y=-2x-\frac{416}{9}[/tex] is a straight line.
Hence, option D is correct.

Step-by-step explanation:
Taylor Swift wants to find the distance, AB, across a river. She starts at point B and walks along the edge of the river 94 ft and marks point C. Then she walks 76 ft further and marks point D. She turns 90° and walks until her final location and marks point E. Point E, point A, and point C are collinear.
Answer:
A) Ms. Swift can conclude that hey are similar, because line E,C,A is collinear, and they both are right triangles.
B) 158.3ft
Step-by-step explanation:
A) Having a collinear line makes the triangles similar, and because of their collinear line they are both right triangles.
B) The question tells you DE is 103 ft. You take 76ft and Square it giving you 5776ft You then take 103 and square it giving you 10609ft adding them together gives you 16385ft you take the square root of it and it gives you the hypotenuse of triangle CDE. To get the hypotenuse of triangle ABC you take The expression (AB/DE)=(BC/CD)=(AC/EC) step one (AB/DE)=(94ft/76ft)=AC/DE) step two (103ft/127ft)=(94ft/76ft)=(AC/DE) third step (103ft/127ft)=(94ft/76ft)=(128ft/158.3)
