1. Create a grid that is 5 squares wide by 2 squares tall. Shade 8 squares as shown above.
A. Look at the shaded:total in the gizmo table. What decimal and percent are modeled by the shaded squares?
Decimal: 0.8Percent: 80%Decimal part =
10 squares
8 shaded
0.2=2 squares shaded
so
8 squares shaded = 0.8
Percent part =
if 100% = 1 whole
1 whole = 10 blocks in gizmo table
then
8 blocks in gizmo table = 80%
since
1 block = 10%
10%x8=80
80%
B. Look at the unshaded:total row. What decimal and percent by the unshaded squares?
Decimal: 0.2Percent: 20%Decimal part:
If there are 2 unshaded squares
and we know that 1 square = 0.1
then, 2 squares = 0.2
0.2
Percent part:
if we know that 10 blocks = 1 whole
and 1 block = 10%
then 2x10%=20%
20%
1. The Gizmo gives two equivalent (equal) fractions — simplified and unsimplified — for the shaded:total and unshaded:total ratios. Record them below. (to see why these are equivalent, notice how many shaded and unshaded squares are in each row of the grid.)
[tex]\frac{shaded}{total}=\frac{8}{10}=\frac{4}{5}[/tex] [tex]\frac{unshaded}{total} =\frac{2}{10} =\frac{1}{5}[/tex]

Answer:
Decimal : 0.8
percent: 80%
decimal: 0.2
percent: 20%
shaded/total = 8/10 = 4/5
unshaded/total = 2/10 = 1/5

We know that:
Given equation: 1/4(x - 2) = 3 - (x + 1/6)Simplify the distributive property.
1/4(x - 2) = 3 - (x + 1/6)=> x/4 - 2/4 = 3 - x - 1/6Further simplify both sides.
x/4 - 2/4 = 17/6 - xSubtract 17/6 both sides.
x/4 - 2/4 - 17/6 = 17/6 - 17/6 - x=> x/4 - 6/12 - 34/12 = -x=> x/4 - 40/12 = -xSubtract x/4 both sides.
x/4 - x/4 - 40/12 = -x - x/4=> -40/12 = -5x/4Use cross multiplication.
=> -160 = -60xDivide -60 both sides.
-160/-60 = -60x/-60=> x = 160/60 = 2 40/60 = 2 2/3A phone company offers two monthly plans. Plan A costs $15 plus an additional $0.14 for each minute of calls. Plan B has no initial fee but costs $0.18 for each
minute of calls.
Answers
Step-by-step explanation:
x = number of minutes
first cost function :
c(x) = 0.14x + 15
the second cost function :
c(x) = 0.18x
I guess, the question (not written in the description) is after how many minutes call time the first plan breaks even with the second plan and further becomes the better choice ?
0.18x = 0.14x + 15
0.04x = 15
x = 15/0.04 = 375
with 375 minutes calling time per month the first plan costs the same as the second plan.
and starting with 376 minutes per month the first plan becomes the cheaper option.
under 375 minutes per month the second plan is the cheaper option.
Madeline uses a scale model of a design she plans to paint on a wall she uses the key 1 CM =1.5 ft. One gallon of paint will cover 400 square feet of wall .How many gallons of paint will Madeline use? Enter your answer as a decimal in the box.
Answers
Madeline would need to use 0.82 gallon of paint
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given the scale 1 cm = 1.5 ft.
(1 cm)² = (1.5 ft.)²; 1 cm² = 2.25 ft²
The area of the figure = area of trapezoid + area of triangle
Area = (1/2) * (10) * (14 + 4) + (1/2) * 14 * (18 - 10) = 146 cm²
146 cm² = 146 cm² * 2.25 ft² per cm² = 328.5 ft²
1 gallon = 400 ft², hence:
328.5 ft² = 328.5 ft² * 1 gallon per 400 ft² = 0.82 gallon
Madeline would need to use 0.82 gallon of paint

Which of the following fractions is equivalent to 1.68? A. 25/42 B. 17/25 C. 42/25 D. 7/4
Answers
Answer:
42/25 or C
Step-by-step explanation:
Just by looking at the answers, we can eliminate A and B because the equivalent decimals of those would result in a number that is less than one.
Then, you can eliminate D because 7/4 is equal to 1.75
Therefore, your answer would be C, 42/25.
Chase found new pants for $35.55 plus 7.5% tax. What is the final price of the new pants?
Answers
Answer:
$38.22
Step-by-step explanation:
7.5% of $35.55 = $2.66625
= $2.67
$35.55 + 2.67 = $38.22 after tax
Answer:
$38.22
Step-by-step explanation:
Given the following question:
7.5% of 35.55
To find the answer we must first find 7.5% of 35.55 using the formula to calculate percentages, and then we add that answer to the current price of the pants.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{7.5\times35.55}{100}[/tex]
[tex]7.5\times35.55=266.625[/tex]
[tex]266.625\div100=2.66625[/tex]
[tex]=2.66625[/tex]
Round the answer to the nearest cent:
[tex]2.66625[/tex]
[tex]6 > 5[/tex]
[tex]=2.67[/tex]
7.5% of 35.55 is "$2.67."
Now we add the answer to the current price:
[tex]35.55[/tex]
[tex]35.55+2.67=38.22[/tex]
[tex]=38.22[/tex]
The cost of the new pants after a 7.5% tax is "$38.22."
Hope this helps.

Find the sum of the following arithmetic sequence. 4,10,16,22,28
Answers
Answer:
Step-by-step explanation:
This is the formula to find the sum of the first
n
terms of the sequence. To evaluate it, the values of the first and
n
the terms must be found .Sn=n2⋅(a1+an)
This is an arithmetic sequence since there is a common difference between each term. In this case, adding
6
to the previous term in the sequence gives the next term. In other words,
an=a1+d(n−1)x Arithmetic Sequence:
d=6 This is the formula of an arithmetic sequence X an=a1+d(n−1)Substitute in the values of a1=4 and d=6 x an=4+(6)(n−1)Simplify each term.
an=4+6n−6 Subtract 6 from 4 x an=6n−2 Substitute in the value of N to find the N the term x a5=6(5)−2 Multiply 6 by 5 x a5=30−2 Subtract 2 from 30 x a5=28 Replace the variables with the known values to find
S5 x S5=52⋅(4+28)Add 4 and 28 x S5=52⋅32
Cancel the common factor of
2.
S5=5⋅16 Multiply 5 by 16 x S5=80

you can calculate this by making a fraction of 28/64 and timing this by 100!
Solution:
Note that:
64 × x/100 = 28Simplifying the LHS:
64 × x/100 = 28=> 64x/100 = 28Using cross multiplication:
64x/100 = 28=> 64x = 2800Divide 64 both sides.

Answer:
please mark me as brainlist pleaseStep-by-step explanation:
The first term is, y2 its coefficient is 1 .
The middle term is, -6y its coefficient is -6 .
The last term, "the constant", is +5
Step-1 : Multiply the coefficient of the first term by the constant 1 • 5 = 5
Step-2 : Find two factors of 5 whose sum equals the coefficient of the middle term, which is -6 .
-5 + -1 = -6 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -5 and -1
y2 - 5y - 1y - 5
Step-4 : Add up the first 2 terms, pulling out like factors :
y • (y-5)
Add up the last 2 terms, pulling out common factors :
1 • (y-5)
Step-5 : Add up the four terms of step 4 :
(y-1) • (y-5)

Is the inverse of a function always a function?explain
Answers
Answer:
Step-by-step explanation:
The inverse of a function may not always be a function! The original function must be a one-to-one function to guarantee that its inverse will also be a function. A function is a one-to-one function if and only if each second element corresponds to one and only one first element. (Each x and y value is used only once.)
Answer:
The inverse is not a function: A function's inverse may not always be a function. The function (blue) f(x)=x2 f ( x ) = x 2 , includes the points (−1,1) and (1,1) . Therefore, the inverse would include the points: (1,−1) and (1,1) which the input value repeats, and therefore is not a function.
