Answer:
32
Step-by-step explanation:
Given, y varies directly as x. So, y=kx, where k is the constant of proportionality.
Given, x=2, y=4. plug in the values in the equation.
4=k*2
k=4/2
k=2
x=16
y=2*16
y=32

c.f<2
d.f<-6
Step-by-step explanation:
option b is the correct answer
Use the equation below to find y, if m= 10, x= 3, and b = 8.
y=mx+b
Answer:
y = 38
Step-by-step explanation:
y=mx+b
y = 10 x 3 + 8
y = 30 + 8
y = 38

According to a report, % of murders are committed with a firearm. (a) If murders are randomly selected, how many would we expect to be committed with a firearm? (b) Would it be unusual to observe murders by firearm in a random sample of murders? Why?
Full question attached
Answer:
A. 230.4
B. 3.23
Explanation:
1. if 78.26% of murders are committed with firearms, 300 murders selected at random would be expected to have been committed with 300*0.7826= 230.4 firearms
2. To find how unusual this figure is, we find standard deviation from the mean 230.4
Standard deviation = x-u/N
=254-230.4/7.311= 3.23 rounded
Therefore 254 is unusual
7.311 is calculated √np(1-p)
Is 1.875 a terminating decimal
Answer:
Because they are fractions, any rational number can also be expressed in decimal form. Any rational number can be represented as either: a terminating decimal: 158=1.875 15 8 = 1.875 , or. a repeating decimal: 411=0.36363636⋯=0.
Step-by-step explanation:
Terminating decimals are those numbers which come to an end after few repetitions after decimal point. Example: 0.5, 2.456, 123.456, etc. are all examples of terminating decimals.

if a box of toffies can be divided among 24 children each will get 4 how many toffies will each get if the number of children is reduced 24
Given : A box of toffies can be divided among 24 and children each will get 4 .
To Find : Number of toffies will each get if the number of children is reduced 24
Solution : If toffies are distributed among the children and each child gets 4 , then the total number of toffies will be equal to , 24 × 4 = 96 toffies .
Again it is given that the toffies are redistributed among 24 children . So the number of toffies each will get will be equal to ,
=[tex]\bf \cancel{\dfrac{96}{24}}[/tex]
=[tex]\Large\boxed{\red{\bf 4 }}[/tex]
Hence the required answer is 4 .

the value of y varies directly with x when y=24, x=2 . what is the value of y when x is 7?
Answer:
84
Step-by-step explanation:
y∞x
y=kx (where k is the constant)
24=2k
24/2=k
12=k
therefore the relationship between k,y and x is y=12x
y=12×7
y=84

Someone answer this for brainliest.
Answer:
x < 3
Step-by-step explanation:
4x - 7 < 5
Add 7 to both sides.
4x < -2
Divide by 4 to both sides to get x alone.
x < 3
To check the answer if it's right or not, you can just plug in the 3 for x and multiply it by 4 which would equal 12 and subtract 12 - 7 which would equal 5.
Hope this helps and pls do mark me brainliest:)

a roofer charges $60 for the first hour of service call and $25 per hour for each additional hour. The roofer also charges a fee for all materials used plus 30% over the cost of the materials. Let r-roofer's cost of materials and h= number of hours worked. What expression could be used to find the cost of a service call
Answer:
y=60+25h+0.3rStep-by-step explanation:
let y be the total charges
given that the hour is h
and the cost for raw material is r
therefore
1. The first hour of service call = $60
2. For each additional hour= 25h
3. 30% over the cost of the materials.= 30/100*r=0.3r
total charges
y=60+25h+0.3r
therefore the expression is
y=60+25h+0.3r
