Answer:
$6250
Step-by-step explanation:
Hello!
First, we find out how much you spend a week.
Since you buy a $5 coffee 5 days a week we multiply the price for a coffee by 5.
5 * 5 = 25.
Next, we find out how much you spend a year.
Since you do it 50 weeks a year we multiply the amount you spend a week by 50
25 * 50 = 1250
Then, we find out how much you spend in 5 years.
We multiply the cost a year by the amount of years
1250 * 5 = 6250
The answer is $6250
Hope this helps!

Answer:
2, -2
Step-by-step explanation:
f(x) = 2x + 1
g(x) = x - 3
To find g(f(x)), you need to put f(x) into g(x).
g(f(x)) = (2x + 1) - 3
g(f(x)) = 2x + 1 - 3
g(f(x)) = 2x - 2
Your answer will be 2 and -2.

What is the next step when solving the following equation?
8x + 8-6 = 60 - 24x - 20
8x + 2 = 40 - 24x
8x + 24x + 2 = 40 - 24x + 24x
32x + 2 = 40
Answer:
8x + 2 = 40 - 24x
Step-by-step explanation:
8x + 8-6 = 60 - 24x - 20
Next step is simplification and is:
8x + 2 = 40 - 24xThe following steps:
8x + 24 x + 2 = 4032x + 2= 4032x = 40 - 232x = 38x = 38/32x = 19/16How would you solve this?

How to do this question plz answer my question
Answer:
$121.82
Step-by-step explanation:
Okay, this is kind of complex, so let's go step by step.
First, we want to find the area of the rectangular lawn - we can do this by multiplying the length and width. The length is 100 and the width is 45 so [tex]45\cdot100=4500[/tex] m² is the area of the rectangle.
However, there are 3 ponds in which the grass seeds will not be going - so we need to find the area of all 3 of these circles and subtract it from 4500 (our rectangle area).
The area of a circle is represented by the formula [tex]\pi r^2[/tex]
The diameters are given here, which is double the radius, so to find the radius of each circle let's divide the diameters by 2.
First circle's radius: [tex]20\div2=10[/tex]
Second circle's radius: [tex]10\div2=5[/tex]
Third circle's radius: [tex]5\div2=2.5[/tex]
Now let's find the area of each circle.
First Circle: [tex]\pi \cdot10^2 = \pi\cdot100=3.14\cdot100=314[/tex]
Second Circle: [tex]\pi\cdot5^2 = \pi \cdot25 = 3.14\cdot25=78.5[/tex]
Third Circle: [tex]\pi \cdot 2.5^2 = \pi \cdot6.25 = 3.14\cdot6.25=19.625[/tex]
Adding all of these values gets us 412.125.
Now we can subtract from this from 4500 to get us 4087.875
If the grass seeds that cost £1.49 cover 50m² each, then we need [tex]4087.875\div50=81.7575[/tex] bags.
Each bag costs £1.49, so the total cost is [tex]81.7575\cdot1.49\approx121.82[/tex]

-280=-7(6a-8)
Answer:
a=8
Step-by-step explanation:
-280=-7(6a-8)
Distribute
-280=-7*6a-7+-8
-280=-42a+56
Subtract 56 from both sides
-336=-42a
Divide both sides by -42.
a=8
Solve the equation
(If possible please show work)
Answer:
[tex]n=-4[/tex]
Step-by-step explanation:
So we have the equation:
[tex]2+4(2-3n)=58[/tex]
First, distribute the second term:
[tex]2+4(2)-4(3n)=58\\2+8-12n=58[/tex]
Add the left side:
[tex]10-12n=58[/tex]
Subtract both sides by 10. The left side cancels:
[tex](10-12n)-10=(58)-10\\-12n=48[/tex]
Divide both sides by -12. The left side cancels:
[tex](-12n)/-12=(48)/-12\\n=-4[/tex]
Therefore, the value of n is -4.
⇒2 + 4(2 - 3n) = 58
⇒4(2 - 3n) = 58 - 2
⇒2*4 - 3n*4 = 56
⇒8 - 12n = 56
⇒-12n = 56 - 8
⇒-12n = 48
⇒-n = 48/12
⇒-n = 4
⇒n = - 4
Hence, value of n is - 4
It takes 3 cats 3 minutes to catch 3 mice. How many cats are needed to catch 99 mice in 99 minutes?
Greetings,
I hope you and your family are staying safe and healthy!
So basically, we have 3 cats catching 3 mice in 3 minutes. That means 1 cat is catching 1 mouse, but it takes it 3 mn.
Now if we have 99 mice and we need to catch them in 99 minutes, we will need 99 cats.
99 cats will catch 99 mice in 99 minutes...meaning each cats will take 1 minute to catch their mice.

Answer:
(x - 8)^2 + y^2 = 3.
Step-by-step explanation:
(x - h)^2 + (y - k)^2 = r^2
Here h = 8, k = 0 and r^2 = (√3)^2 = 3
The answer is (x - 8)^2 + (y - 0)^2 = 3
or (x - 8)^2 + y^2 = 3.

A triangle has side lengths of (8.1t-6.1)(8.1t−6.1) centimeters, (8.1t+7.1)(8.1t+7.1) centimeters, and (3.4u+1.9)(3.4u+1.9) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
(16.2t+3.4u+2.9)cm
Step-by-step explanation:
A triangle is a plane shape that has three sides. The perimeter of a triangle is gotten by taking the sum of all the lengths of the three sides. Let the length of the three sides by s1, s2 and s3, the perimeter of the triangle will be expressed as;
P = s1+s2+s3
Given the side lengths
s1 = (8.1t-6.1)cm
s2 = (8.1t+7.1)cm
s3 = (3.4u+1.9)cm
Perimeter of the triangle = 8.1t-6.1+8.1t+7.1+3.4u+1.9
collect the like terms
P = 8.1t+8.1t+3.4u-6.1+7.1+1.9
P = 16.2t+3.4u+2.9
Hence the expression that represents the perimeter, in centimeters, of the triangle is (16.2t+3.4u+2.9)cm

Find the volume and total surface area of the composite figure below.
Answer:
Volume = 6467.492mm³
Surface area = 1332.035mm²
Step-by-step explanation:
volume of a cone is [tex]\pi[/tex]r²h. V=[tex]\pi[/tex]10²(24)=7539.822mm³
volume of a sphere is 4/3[tex]\pi[/tex]r³. V=4/3[tex]\pi[/tex](8³)=2144.66mm³
Since it's a half of a sphere, it would be 1072mm.33³
7539.822-1072.33=6467.492mm³
Surface area of a cone is [tex]\pi[/tex]r(r+√h²+r²)=1130.97
area of a circle= [tex]\pi[/tex]r²=201.06
surface area of a sphere is 4[tex]\pi[/tex]r²=804.25
Since it's a half sphere, it would be 402.125
1130.97-201.06+402.125=1332.035mm²

Find the value of the variable. if Y is between X and Z.
segment XY = 4a and segment YZ = 9a and segment XZ = 6a+24
Answer:
[tex]\bold{a = \dfrac{24}{7}}[/tex]
Step-by-step explanation:
Kindly refer to the attached for the values labelled to the line XZ.
The point Y is in between XZ.
It can be clearly observed that XZ is made up of sum of two lines XY and YZ.
So, we can write:
XZ = XY + YZ ....... (1)
We are given the values of line segments:
XY = 4a
YZ = 9a and
XZ = 6a+24
To find: Value of variable 'a'.
Solution:
Putting all the values in equation (1):
[tex]6a+24 = 4a + 9a\\\Rightarrow 6a+24=13a\\\Rightarrow 7a=24\\\Rightarrow \bold{a = \dfrac{24}{7}}[/tex]
So, value of variable is
[tex]\bold{a = \dfrac{24}{7}}[/tex]
