Answer:
Yes, both have the same value ( 20) when x = 5.
Step-by-step explanation:
We have two functions:
y = 15 + x
y = 4*x
We want to see if these functions have the same value when x = 5.
Then we just need to replace x by 5 in both equations, and see if the values of y are the same
first function:
y = 15 + 5 = 20
second function:
y = 4*5 = 20
So yes, both functions are equal to 20 when x = 5.
Answer:
Yes.
Step-by-step explanation:
4(5)=20
15+5=20
Helen goes into a shop.
She wants to buy 2 shirts and a pair of shorts,
Each shirt costs £24.50
The pair of shorts costs £18.90
Helen only has £70 to spend,
Does Helen have enough money to buy the 2 shirts and the pair of shorts?
Answer:
yes
Step-by-step explanation:
2*24.50=49 (two shirts)
18.90 (pair of shorts)
49+18.90=67.90
she can spend 70, means she can buy all of those and she still has 2.10

In ∆EFG, the measure of angle G=90,the measure of E=77, and GE=2.6 feet. Find the length of FG to the nearest tenth of a foot.
Step-by-step explanation:
Using Trignometry,
tan77° = Opposite/Adjacent = FG/GE.
Therefore FG = GEtan77°
= (2.6)tan77° = 11.3 feet.

Answer:
I believe D is the answer
Step-by-step explanation:
how I find the slope it by looking at the y-axis and what hits directly on that line. you can see that 3 hits directly on that line so the b in y=mx+b is three which is your starting point. then you follow the line and see where it hits directly on a point. then count the blocks. remember that it's rise over run so that's y over x. so you go down five and over one. since you go down five it's negative. the negative is only added onto the five not the one. and since it's five over one, you don't need to put the over one, it's just automatically there. hope this helps! good luck!

Three students have already enrolled for a creative writing class. The teacher will cancel the class if there are fewer than 10 students enrolled. Write three values for numbers of students needed to sign up so that the the creative writing class can be held
Answer:
7, 10 and 15
Step-by-step explanation:
Given
[tex]S_1= 3[/tex] --- Students already enrolled
[tex]Total = 10\ (less)[/tex]
Required
Determine the additional number of students needed for the teacher not to cancel the class
First, we need to calculate the number of students for the teacher to cancel the class.
Represent this with x.
So, we have:
[tex]S_1 + x < Total[/tex]
Make x the subject
[tex]x < Total - S_1[/tex]
Substitute values for Total and S1
[tex]x < 10 - 3[/tex]
[tex]x < 7[/tex]
This means that if less than 7 additional students come to the class, the teacher will cancel the class.
So, for the teacher not to cancel the class, the students must be 7 or greater (i.e. 7, 8, 9, 10....)

s is inversely proportional to t
When s = 0.5, t = 7
Work out s when t = 0.8
Given:
s is inversely proportional to t.
When s = 0.5, t = 7.
To find:
The value of s when t=0.8.
Solution:
s is inversely proportional to t.
[tex]s\propto \dfrac{1}{t}[/tex]
[tex]s=\dfrac{k}{t}[/tex] ...(i)
Where, k is the constant of proportionality.
Putting s=0.5 and t=7, we get
[tex]0.5=\dfrac{k}{7}[/tex]
[tex]0.5\times 7=k[/tex]
[tex]3.5=k[/tex]
Putting k=3.5 in (i), we get
[tex]s=\dfrac{3.5}{t}[/tex]
This is the equation of proportionality.
Putting t=0.8, we get
[tex]s=\dfrac{3.5}{0.8}[/tex]
[tex]s=4.375 [/tex]
Therefore, the value of s is 4.375 when t=0.8.

Rita is designing a building shaped like a pyramid that's cut off in a plane parallel to its base (this is called a truncated pyramid). The building has a 64×64 m end text square base and is 36 m tall. The cut off section has an a16×16m square base and is 12 m tall. What is the volume of the building? Round to the nearest cubic meter.
Answer:
64,512 m3
Step-by-step explanation:
3 1
(base area)(height) = 3 1
(64⋅64)(48) =65,536
The volume of the building is 64512 cubic meters if the pyramid that's cut off in a plane parallel to its base.
What is a right square pyramid?In geometry, it is defined as the shape having a square base with equal sides length and all the vertex of the squares joints at the top which is perpendicular to the center of the square.
We know volume for the right square pyramid is given by:
[tex]\rm V= \frac{1}{3} b\times h[/tex]
Volume for the cut off portion:
[tex]\rm v = \dfrac{1}{3}\times16\times16\times12[/tex]
v = 1024 cubic meters
Volume for the completer pyramid"
[tex]\rm V=\dfrac{1}{3}\times64\times64\times48[/tex]
V = 65536 cubic meters
Volume of the building = 65536 - 1024
= 64512 cubic meters
Thus, the volume of the building is 64512 cubic meters if the pyramid that's cut off in a plane parallel to its base.

Ashley is making trail mix.The ratio of peanuts to raisins in one portion is 5:9. Create a ratio table to find out how many peanuts and raisins you will need if you make 7 portions and 12 portions
The number of peanuts and raisins for 7 portions is 35 and 63 respectively.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given that, the ratio of peanuts to raisins in one portion is 5:9.
Number of peanuts and raisins you will need if you make 7 portions and 12 portions.
Now, 5×7 : 9×7
35:63
Here, 5×12 : 9×12
60 : 108
Therefore, the number of peanuts and raisins for 7 portions is 35 and 63 respectively.

If we know the ration, and we are given the adults, we can set up a proportion in order to solve for the amount of children there are.
5:2=35:x
5x=35*2
5x=70
x=14
There are 14 children

A triangle has a base of 18.1 kilometres and a height of 17.4 kilometres. What is the area?
Answer:
157.47km²
Step-by-step explanation:
Given the following
base of 18.1 kilometres
height of 17.4 kilometres
Area of the triangle = 1/2 * base * height
Area of the triangle = 1/2 * 18.1 * 17.4
Area of the triangle = 314.94/2
Area of the triangle = 157.47km²
Hence the area of the triangle is 157.47km²
