Answer:
14
Step-by-step explanation:
Given that:
Quarters, x = 25 cent
Nickel, y = 5 cent
Total number of coins = 42
Total worth = $4.90 = 490 cents
x + y = 42 - - (1)
25x + 5y = 490 - - - (2)
y = 42 - x
25x + 5(42 - x) = 490
25x + 210 - 5x = 490
20x = 280
x = 280 / 20
x = 14
x = quarters = 14
X=?

Work out the two possible values of b.
Answer:
21
Step-by-step explanation:
Given:a²=36
a=✓36
a=6
a:b=2:7
6:b=2:7
can be written as
6/b=2/7
2b=6*7

Find the nth term rule for the sequence: 20, 28, 36, 44
Answer:
a(n) = 12 + 8n
a1 = 20
a2 = 28 = 20 + 8
a3 = 36 = 20 + 8.2
a4 = 44 = 20 + 8.3
.......
=> this is a arithmetic with a1 = 20
d = 8
=> an = 20 + 8(n - 1) = 12 + 8n

The radius of a circle is 4 meters. What is the circle's circumference?
r=4m
Use 3.14 for pie
This value is approximate because pi = 3.14 is approximate
===========================================================
Work Shown:
r = 4 = radius
pi = 3.14 approximately
C = circumference
C = 2*pi*r
C = 2*3.14*4
C = 25.12
The circumference is approximately 25.12 meters.
Side note: The circumference is the same as the perimeter of a circle.

-5x + 11 = -8(4 + 6x) What are the steps?
Answer:
[tex]x = - 1[/tex]
Step-by-step explanation:
[tex] - 5x + 11 = - 8(6x + 4)[/tex]
[tex] = > - 5x + 11 = - 48x - 32[/tex]
Lets keep the variable terms in L.H.S. and the constant terms in R.H.S.
[tex] = > 48x - 5x = - 32 - 11[/tex]
[tex] = > 43x = - 43[/tex]
Lets divide 43 on both the sides.
[tex] = > \frac{43x}{43} = \frac{ - 43}{43} [/tex]
[tex] = > x = - 1[/tex]
A container is in the shape of a cuboid the cuboid is 2/3 full of water a cup holds 275 ml of water what is the greatest number of cups
Answer:
12 cups
Step-by-step explanation:
The first step is to calculate the volume of the cubiod
= 36 × 6 × 23
= 4968
= 4968/3 ×2
= 1656×2
= 3312
Therefore the greatest number of cups can be calculated as follows
= 3312/275
= 12
Hence the greatest number of cups is 12 cups
Brian and Mark are fishing. They both catch a fish. Brian's fish weighs 17
pounds less than Mark's fish. Mark's fish weighs 22 pounds
PLEASE HURRY.
Answer: 5 pounds
Step-by-step explanation:
We need to find how much Brian's fish weighs. We know that Mark's fish weighs 22 pounds, and Brian's fish weighs 17 pounds less than Mark's fish. To find how much Brian's fish weighs, we can subtract 17 from 22.
22 - 17 = 5.
Therefore, Brian's fish weighs 5 pounds.
Hope this helps, and good luck :D
Answer:
5 pounds
Step-by-step explanation:
22-17 =5

Tickets for the karaoke talent show sponsored by the Speech Club were priced at $3 for adults and $2 for students. The club treasurer counted 300 tickets sold for a total of $650. Write and solve a system of equations to determine how many adult and student tickets were sold.
Answer:
50 adults and 250 students tickets were sold
Step-by-step explanation:
Given data
Let the number of adults be x and students be y
3x+2y=650------1
x+y= 300---------2
from 2
x= 300-y
put the value of x in 1
3(300-y)+2y= 650
900-3y+2y= 650
900-y= 650
900-650= y
y=250
put the value of y in 2
x+250= 300
x= 300-250
x= 50
Hence 50 adults and 250 students tickets were sold
On 9th May, 2009, there were 3440 people in the world with swine flu. Of these people, 1639 were in the USA. The 3440 people who had swine flu on 9th May was an increase of 37.6% on the number of people who had swine flu on 8th May. Calculate the number of people who had swine flu on 8th May.
Answer:
2500
Step-by-step explanation:
let a represent the number of people that had swine flu on the 8th of May
a increased by 37.6% on the 9th of May. The 37.6% increase is equal to 3440
the equation that can be used to represent this is:
a x 1.376 = 3440
to find a, divide both sides by 1.376
a = 2500

-21
Step-by-step explanation:
put in -3 where x is
-3^2 9

Answer:
-21
Step-by-step explanation:
We know that [tex]f(x)=-x^2-12[/tex] and we also know that [tex]f(x)=f(-3)[/tex]. Therefore, you will have to substitute x with -3.
Calculations:
[tex]f(x)=-x^2-12[/tex]
[tex]f(-3)=-(-3)^2-12[/tex]

What is the slope of y = -4?
Answer:
0
Step-by-step explanation:
The line is horizontal.
Explanation:
Think of y = -4 as y = 0x+(-4)
We see that the equation matches the form y = mx+b
m = 0 = slope
b = -4 = y intercept
Side note: this equation graphs out a horizontal line. All horizontal lines have a slope of 0.

Answer:
Since 1/5 is 0.2
and 1/5 × 9 is 9/5
We can do 0.2 × 9
which you should get 1.8
OR you can do 0.2 + 0.2 + 0.2 +0.2 +0.2 + 0.2 + 0.2 + 0.2 + 0.2 (which is 0.2 added 9 times)
Which also results in 1.8
Answer:
she could mabey multiply 9x0.2=1.8
Step-by-step explanation:
it might be 1.8 because if 1/5=0.2 and she needs to find out what 9/5 is so
you need to multiple 9x0.2 but im not sure if im right

Which of the following equations have no solutions?
Choose all answers that apply:
A
152 - 45 = 750 + 75
B.
15% - 45 = 15x + 75
c
45x – 45 = -15% + 75
D
-450 – 45 = -75x + 75
Answer: B
Step-by-step explanation:
Equation A:
15x - 45 = 75x + 75
=> -120 = 60x
=> x = -2
Equation B:
15x - 45 = 15x + 75
=> 0 = 15
No Solutions
Equation C:
45x - 45 = -15x + 75
=> 60x = 120
=> x = 2
Equation D:
-45x - 45 = -75x + 75
=> 30x = 120
=> x = 4
