Could someone help me complete this chart? It’s kinda confusing.
Answer:
1. - completed
2. expanded = a · a · a · a
3. base = a | exponent = 5 | expanded = a · a · a · a · a
4. - completed
5. base = c | exponent = 3 | expanded = c · c · c
6. base = c | exponent = 4 | expanded = c · c · c · c
7. base = m | exponent = 2 | expanded = m · m
8. base = m | exponent = 3 | expanded = m · m · m
9. power = y⁵ | base = y | exponent = 5
10. power = y⁸ | expanded = y · y · y · y · y · y · y · y

Charlie has a giant bag of gumballs and wants to share them with his friends. He gives half of what he has to his buddy, Jaysen. He gives half of what's left after that to Marinda. Then he gives half of what's left now to Zack. His mom makes him give 5 gumballs to his sister. Now he has 10 gumballs left. How many gumballs did Charlie have to begin with?
Answer:
120 gumballs
Step-by-step explanation:
Let
x = total gumballs
Buddy = 1/2x
Balance = x - 1/2x
= 2x-x/2
= 1/2x
Miranda = 1/2 of 1/2x
= 1/2 × 1/2x
= 1/4x
Balance = 1/2x - 1/4x
= 2x-x/4
= 1/4x
Zack = 1/2 of 1/4x
= 1/2 × 1/4x
= 1/8x
Balance = 1/4x - 1/8x
= 2x-x/8
= 1/8x
His sister = 5
Balance = 1/8x -5
10 = 1/8x - 5
10 + 5 = 1/8x
15 = 1/8x
x = 15 ÷ 1/8
= 15 × 8/1
= 120
x = 120 gumballs
You buy
3.16 pounds of
pears,
1.15 pounds of
apples, and
2.18 pounds of
peaches. What is your total bill?
1.19 pears, 0.99 apples, 1.29 peaches
Answer:
if the prices at the bottom are per pound, then:
pears = 3.7604 (3.76)
apples = 1.1385 (1.13)
peaches = 2.8122 (2.81)
total bill = 7.07
Step-by-step explanation:
pears =
1.19 x 3.16 = 3.7604 (3.76)
apples =
0.99 x 1.15 = 1.1385 (1.13)
peaches =
1.29 x 2.18 = 2.8122 (2.81)
total bill =
3.76 + 1.13 + 2.81 = x
x = 7.7
7.7 money-wise = 7.07 (i think)
total bill = 7.07
OR
total bill =
3.7604 + 1.1385 + 2.8122 = x
x = 7.7111
----------------
7.7111 = 7.7 = 7.07
Tom the turkey is 2.5 feet tall and he casts a shadow that is 4 feet. The Thanksgiving Parade float version of Tom is 14 feet tall. How long is the shadow of the parade float?
Answer:
22.4 ft
Step-by-step explanation:
Given
[tex]Height = 2.5ft[/tex]
[tex]Shadow = 4ft[/tex]
Required
Determine the shadow of 14 ft Tom
The given parameters represents direct variation.
Let x represents the shadow of Tom.
So, we have:
When
[tex]2.5ft\ height = 4ft\ Shadow[/tex]
[tex]14ft\ height = x[/tex]
Cross Multiply:
[tex]2.5 * x = 14 * 4[/tex]
[tex]2.5 * x = 56[/tex]
Solve for x
[tex]x = 56/2.5[/tex]
[tex]x = 22.4[/tex]
Hence, the height of the shadow is 22.4ft
Part A )a painter leans a ladder up against a building. The base of the ladder is placed 7 feet from the building to reach a height of 24 feet. How long is the ladder
Part B) The painter uses the same ladder from part A, but now needs to reach a height of 19 feet.How far away does the base of the ladder need to be placed from the building?
Answer:
Part A). 25 feet
Part B). 16.25 feet
Step-by-step explanation:
Part A). By applying Pythagoras theorem in ΔABC,
AC² = AB² + BC²
AC² = (24)² + 7²
AC² = 576 + 49
AC = √625
= 25 feet
Part B). By applying Pythagoras theorem in ΔABC,
AC² = AB² + BC²
(25)² = (19)² + x²
625 = 361 + x²
x² = 625 - 361
x = √264
x = 16.25 feet

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
y = -3x - 2
4y = -12x - 8
Step 2: Solve for x
Substitute in y: 4(-3x - 2) = -12x - 8Distribute 4: -12x - 8 = -12x - 8Add 8 to both sides: -12x = -12xDivide both sides by -12: x = xHere we see that x does indeed equal to x. Therefore, x can be any value.
∴ The systems of equations have infinite amount of solutions.

Los lados de un cuadrilátero mide 6,8,7,9con tal como se muestra en la figura si se realiza una producción sensual y al lado correspondiente a 7ck haora mide 12cm ¿cuánto debe medir los demás lados
Answer:
The other sides 6,8, and 9 will be11cm, 13cm, and 14cm respectivelyStep-by-step explanation:
Step one:
given that the sides of the quadrilateral are:
6,8,7, and 9 in dimension.
And the side corresponding to 7 now measures 12
we may agree that the side has increased by 5cm, hence 5 has been added to that side.
Step two:
we can say that the other side will increase as follows
[tex]side_6= 6+5= 11cm\\\\side_8=8+5=13cm\\\\side_9=9+5=14cm\\\\[/tex]

Step-by-step explanation:
Suppose the man in the St. Ives poem has x wives, each wife has x sacks, each sack has x cats, and each cat has x kits. Write an expression using exponents that represents the total number of kits, cats, sacks, and wives going to St. Ives.
Answer: [tex]x+x^2+x^3+x^4[/tex]
Step-by-step explanation:
As per given,
Number of wives = [tex]x[/tex]
Number of sacks = [tex]x (\text{Number of wives} )= x\times x = x^2[/tex]
Number of cats = [tex]x(\text{Number of sack})[/tex][tex]= x \times x^2=x^3[/tex]
Number of kits = [tex]x(\text{Number of cats} )=x\times x^3=x^4[/tex]
Now , the total number of kits, cats, sacks, and wives going to St. Ives = [tex]x+x^2+x^3+x^4[/tex]
Hence, the required ex[pression: [tex]x+x^2+x^3+x^4[/tex]
