The square in the middle has an area of 1 square unit. What is the area of the entire rectangle in square units? Explain your reasoning. A rectangle composed of 2 small tangram triangles, 2 medium tangram triangles, and 1 tangram square.
Answer:
about 3
Step-by-step explanation:
i think ..........................
The required area of the rectangle is 4 square units.
Given that,
The square in the middle has an area of 1 square unit. A rectangle is composed of 2 small tangram triangles, 2 medium tangram triangles, and 1 tangram square.
To determine the area of the entire rectangle in square units.
What is a rectangle?the rectangle is a four-sided polygon whose opposites sides are equal and has an angle of 90° between its sides.
Here,
Since the area of square = 1
side² = 1
side = √1
Side = 1
Width of rectangle = √[1 ²+ 1²] (diagonal of square)
Width of rectangle = √2
Length of rectangle = 2 √[2² - √2²]
Length of rectangle = 2 √[4-2]
(with the help of the Pythagorean theorem on the larger triangle )
Length of rectangle = 2 √2
Area of the rectangle = length * width
Area of the rectangle = 2√2 * √2
Area of the rectangle = 2 * 2
Area of the rectangle = 4
Thus, the required area of the rectangle is 4 square units.

Evan spent 20 hours doing homework last week. This week he spent 25 hours doing homework. He says that he spent 125% more time doing homework this week. Is he correct? Show your work to justify your decision.
Answer:
25/20 =1.25 -1 =.25 x 100 =25% more time spent on his HW.
Step-by-step explanation:
Answer:
Evan spent 25 percent more time. Not 125 percent.
I used a proportion to answer this questions.
20=25
100 ?
You cross multiply: 25 times 100 is 2,500. 2,500 divided by 20 is 125.
So Evan is incorrect
If this is wrong I'm sorry

Diego has $11 and begins saving $5 each week toward buying a new phone. At the same time that Diego begins saving, Lin has $60 and begins spending $2 per week on supplies for her art class.
1. After how many weeks will they have the same amount of money?
after ____ weeks.
2. How much do they have at that time?
$ ____.
Answer:
1. It should be 7
2. They have $46
Step-by-step explanation:
1. You make a system of linear equations from this. So it would be y= 5x+11 where x is the number of weeks and y is the money. And the second linear equation is y=-2x+60. Then you substitute it. You make it 5x+11=-2x+60. Then you solve it normally and you got your answer but remember in this case they are asking for the x. So make sure to submit the x and not the y.
2. For this it is the same thing except they are asking for the y not the x.

Vodafone is charging a flat fee of $90 per month regardless of calling time. Let C1 be the Vodafone monthly cost. Express the monthly cost in the equation. Start with C1=
A. C1=90*m
B. C1=90
C. C1=m+90
Let's examine Telefónica which is charging $50 per month and additional 20 cents fee per minute of calling time. Let C2 be the monthly cost in dollars at Telefónica and m - minutes spend on the phone. Write an equation to model monthly cost. TIP: Do not forget to turn cents into dollars. Start with C2= *
A. C2=50+20m
B. C2=50+0.20m
C. C2=50*20m
With these 5 hours of calling time in mind, calculate and show the cost of phone service for Vodafone
A. C1=90*5=$450 (very expensive plan!)
B. C1=90 (cost stays the same at $90 regardless of usage)
C. C1=90+minutes
And now calculate and show the monthly cost for Telefónica with 5 hours of calling time in mind. Do not forget to convert hours into minutes *
A. C2=$50
B. C2=50+0.20*5=$51
C. C2=50+0.20*300=$110
Which plan works best for Kira? Why?
Is there a point (in terms of minutes) when the monthly cost is the same for both phone companies? Explain

Step-by-step explanation:
Answer:
Every term in Q(x) will have an x associated with it except the last one which is "1"
And the y intercept of the function will have an associated x value of 0
So......evey term will evaluate to 0 except the last one
So.....the y intercept of Q(x) = 1

A recipe for sparkling grape juice calls for
1/2
quarts of sparkling water and 3/4
quarts of grape juice
a. How much sparkling water would you need to mix with 9 quarts of grape juice?
b. How much grape juice would you need to mix with 15/4
quarts of sparkling water?
c. How much sparkling water would you need to make 100 quarts of punch?
d. How much grape juice would you need to make 100 quarts of punch?
Answer:. A.) 6 quarts
B.) 45/8 quarts
C. 40 quarts sparkling water and 60 quarts of grape juice.
Once you get the basic ratio which is the amount of sparkling water is 2/3 the amount of grape juice, you can use that to set up as n equation for the next two questions.
Step-by-step explanation:
15/4 = 2x/3
Multiply both sides by the reciprocal:
3/2(15/4 = 3/2(2x/3)
45/8 = x
That is 5 5/8 quarts when simplified.
15/4 is 3 3/4 quarts
2 parts sparkling water to 3 parts grape juice is another useful ratio. Using that, 2x + 3x= 100 we can calculate
5x = 100
x 20. 2(20)=40 and 3(20)= 60
factor the expression: 8x + 12
Answer: i think th answer is 4 ( 2x + 3 )
Step-by-step explanation:
8x + 12
(rewrite 12 comp 4 * 3)
(rewrite 8 as 4 * 2)
4 * 2x + 4 * 3
4 (2x + 3)
