10 ÷2 = 5
so, 2 x 5 plus 2= 12
p= 5
The total value of the coins is 3.88. Anita has 4 more nickels than pennies and 2 more than 4 times the number of quarters than pennies. How many of which coins does she have?
Answer:
See explanations below
Step-by-step explanation:
Let the amount of nickel be x
Let the amount of pennies be y
Let the amount of quarters be z
If the the total value of the coins is 3.88, then;
x+y+z = 3.88 .... 1
If Anita has 4 more nickels than pennies, then;
x = y + 4 ... 2
If she has 2 more than 4 times the number of quarters than pennies, then;
y = 2 + 4z
4z = y-2
z = (y-2)/4 ...3
Substitute 2 and 3 into 1
y+4+y+(y-2)/4 = 3.88
4y+16+4y + y-2 = 15.52
9y + 14 = 15.52
9y = 15.52 - 14
9y = 1.52
y = 1.52/9
y = 0.17
Since x = y + 4
x = 0.17+4
x = 4.17
z = y-2/4
z = 0.17-2/4
z = -1.83/4
z = - 0.46

The area of the rectangular computer chip is 112a3b2 square microns. Write a simplified expression that represents the length. The length is ? microns.
Question:
The area of a rectangular computer chip is 112a^3b^2 square microns. Write a simplified expression that represents the length, if the width is 8ab
Answer:
[tex]Length = 14a^2b[/tex]
Step-by-step explanation:
Given
[tex]Area = 112a^3b^2[/tex]
[tex]Width = 8ab[/tex]
Required
Determine the height
Area is calculated as:
[tex]Area = Length * Width[/tex]
Make Length the subject
[tex]Length = \frac{Area}{Width}[/tex]
[tex]Length = \frac{112a^3b^2}{8ab}[/tex]
[tex]Length = \frac{14a^3b^2}{ab}[/tex]
Apply law of indices
[tex]Length = 14a^{3-1}b^{2-1}[/tex]
[tex]Length = 14a^2b[/tex]
Does the number triple 5, 6, and 8 represent the lengths of sides of a right triangle? Explain. Will give Brainliest
Answer:
no
Step-by-step explanation:
to be a right triangle the smaller two sides squared & added together would equal the square of the longer side
does 5² + 6² = 8²?
25 + 36 = 61, not 64 so it is not a right triangle

Answer:
C= 93⁰, B= 64⁰, D= 23⁰
Step-by-step explanation:
180= (4x + 1) + (3x - 5) + x⁰
180= 4x+1 +3x-5 +x
180= 8x - 4
184= 8x
184/8= x
23=x
therefore
C= (4(23) +1)
C= 93
B= (3(23)-5)
B= 64
D= 23
93⁰+64⁰+23⁰=180⁰
About 32% of the 104 children ate a school picnic ate hamburgers. The rest ate hotdogs. How many children ate hotdogs at the picnic
Answer: 71 children ate hotdogs at the picnic.
Step-by-step explanation:
Given: About 32% of the 104 children who ate a school picnic ate hamburgers.
The number of children ate hamburger = 32% of (104 children)
= 0.32 x 104
= 33.28 ≈ 33
Thus, the number of children ate hamburger = 33
Number of children ate hotdogs = 104-33 = 71
Hence, 71 children ate hotdogs at the picnic.
A rectangular sandbox is in the center of a larger rectangular back yard. The sand box
measures (x+6) feet long and 5x feet wide. The yard measures (6x+7) feet long and 8x
feet wide.
What is the area of the yard that is NOT apart of the sandbox?
Answer:
(43[tex]x^{2}[/tex] - 26x) [tex]ft^{2}[/tex]
Step-by-step explanation:
Area of the yard that is not pat of the sandbox = Area of the yard - Area of the sandbox
Since both the yard and the sandbox has a rectangular shape, then;
Area of a rectangle = length x width
So that,
Area of the yard = length x width
= (6x+7) x 8x
= (48[tex]x^{2}[/tex] + 56x) [tex]ft^{2}[/tex]
Area of the sandbox = length x width
= (x+6) x 5x
= (5[tex]x^{2}[/tex] + 30x) [tex]ft^{2}[/tex]
Thus,
Area of the yard that is not pat of the sandbox = (48[tex]x^{2}[/tex] + 56x) - (5[tex]x^{2}[/tex] + 30x)
= 48[tex]x^{2}[/tex] + 56x - 5[tex]x^{2}[/tex] - 30x
= (43[tex]x^{2}[/tex] - 26x) [tex]ft^{2}[/tex]
Area of the yard that is not pat of the sandbox is (43[tex]x^{2}[/tex] - 26x) [tex]ft^{2}[/tex].

Felicity cuts 27 equal strips from a 6-yard spool of ribbon. Which expressions show the number of yards for one strip of ribbon
Answer:
2/9 yards
Step-by-step explanation:
Felicity cuts 27 equal strips from a 6-yard spool of ribbon. Which expressions show the number of yards for one strip of ribbon
From the above question:
27 equal strips of ribbon = 6 yards of spool
1 strip of ribbon = x yards
Cross Multiply
27 strips of ribbon × x yards = 6 yards × 1 strip of ribbon
x yards = 6/27
x yards = 2/9 yards
Therefore, for 1 strip of ribbon we need 2/9 yards

PLEASE HELP ME WITH THIS
Please answer the question above.
Answer:
50
Step-by-step explanation:
We know angles in a straight line add up to 180, therefore:
2x + 50 + 30 = 180
2x + 50 = 180 - 30
2x + 50 = 150
2x = 150 - 50 = 100
2x = 100
x = 50
Answer:
Step-by-step explanation: Since we know the angle of a line is 180 degrees. We can use that.
1. 180-30 because we already know that angle is 30 degrees.
2. We are left with 150 degrees so we know the large angle is 150 degrees to check we do this.
3. 150=2x+50
4. 100=2x Divide both sides by two and get
5. x=50

Oceanside Bike Rental Shop charges a 13 dollar fixed fee plus 9 dollars an
hour for renting a bike. Carlos paid 58 dollars to rent a bike. How many
hours did he pay to have the bike checked out? *
Answer: 5 hours
Step-by-step explanation:
Carl paid $58 dollars in total and this included the fixed dollar fee and the variable amount of $9.
To find the number of hours, first deduct the fixed component:
= 58 - 13
= $45
$45 was spent as a result of hourly fee. The number of hours is therefore:
= Total hourly cost/ Cost per hour
= 45 / 9
= 5 hours

If the length of SR is 4 meters and the length of ST is 8 meters , what is the length of PQ in meters
Answer:
the length of PQ is 8.9 m
Step-by-step explanation:
The computation of the length of PQ in meters is shown below:
Here we applied the Pythagoras theorem
c² = a² + b²
= 4² + 8²
= 16 + 64
= 80
Now square root to the both sides
c = √80
= 8.94427191
= 8.9 m
Hence, the length of PQ is 8.9 m
