What is the area of the figure below?

Answer:

120/100 a = 80/100 b

12/10 a = 8/10 b

10 (12/10) a = 10 (8/10) b

12a= 8b

3a= 2b

a+b in terms of a

b = 3/2×a

a+ 3/2×a = 5/2×a

a+b in terms of b

a = 2/3×b

b + 2/3.b = 5/3×b

What you have to do is first subtract 20 from 80 and get 60 then use the data to fill in the blanks!

Answer:

rectangle triangle trapezium

Step-by-step explanation:

rectangle =length×width(12×7=84)

triangle=1/2base×height(1/2×8×7=28)

trapezium=1/2sum of parallel lines ×height(1/2×(6+2)×7=28)

area of the rectangle subtract area of two trapeziums. (84-{28×2}=28)

Answer:

C is the answer

Step-by-step explanation:

1. distribute (multiply) -6 to 4

2. than -r

3. answer would be -24 - 6 = 30

-6r shouldn't be positive. It should stay negative

Answer:

180-(45+90)

Step-by-step explanation:

180-(135)

45

Answer is 45

Answer:

45°

Step-by-step explanation:

→ First solve the values within the brackets

45° + 90° = 135°

→ Resubstitute back

180° - 135°

→ Solve

45°

Step-by-step explanation:

Since he has $20 and spends $5.25 on shoes, that means he will have $14.75 left for games. Since each game is $4, he can play 3 and be at at total cost of $17.25, but if he plays 4 games he will be at $21.25. Therefore, he can play 3 games.

Answer:

$4

Step-by-step explanation:

Because with no distance traveled, the fixed amount charged would be $4. For every mile traveled, there is an additional $5. So your correct answer is $4.

Answer:

Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.

Sarah can use the expression 5(2j + 3 + j) to represent the amount of money they can earn.

Part 1: Writing Expressions

Q1. Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.

25(10j + 18 + 5j)

Your expression is good.

Q2. Translate the new algebraic expression you created in Question 1 to a verbal expression.  

Skuttle offered to pay his sister Izzy $25 for every four leaf clover she finds in the woods. Izzy finds 18 clovers but decides to get Roxy’s help. Izzy finds clovers twice as fast as Roxy but they will over all make more money together.

Your verbal expression is good. It refrects your chosen equation.

Part 2: Writing Equivalent Expressions

Q3. Use your knowledge of the mathematical properties to create two equivalent algebraic expressions for the algebraic expression you created in Question 1. Explain how you arrived at the equivalent expressions by showing all your steps and stating which properties you used.

Using commutative property of addition, the expression in question 1 can be rewritten as follows:

25(10j + 18 + 5j) = 25(10j + 5j + 18)

Using distributive property of multiplication over addition, the expression in question 1 can also be rewritten as follows:

25(10j + 18 + 5j) = 250j + 450 + 125j

Q 4. Use substitution to prove your algebraic expressions are equivalent. You may substitute any number for the variables you choose. Show all your work for complete credit.

Now we can subsitute, say 7 for j.

For the first expression, we have:

25(10j + 5j + 18) = 25(10(7) + 5(7) + 18)

= 25(70 + 35 + 18) = 25(123) = 3,075.

For the second expression, we have:

250j + 450 + 125j = 250(7) + 450 + 125(7) = 1,750 + 450 + 875 = 3,075.

Thus, we can see that both expressions are equivalent.

Part 3: Finish the Story

Q5. Write a few sentences to end Sarah’s story. How many shark teeth did she find? How many shark teeth did John find? How much money did they earn?

Sarah found 3 + 7 = 10 shark teeth.

John found 10 / 2 = 5 shark teeth.

The total money they earned is $5 x 15 = $75.

Answer:

The cell phone company sold 1,500 phones that day.

Step-by-step explanation:

450 x 100 = 45,000

45,000 ÷ 30 = 1,500

The speed for the given distance and time is 12.6 miles per hour.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Given that, a car drives [tex]10\frac{1}{2}[/tex] miles in 1/6 hour.

We know that, the formula to find the speed is Speed=Distance/Time

Speed = [tex]10\frac{1}{2}[/tex] ÷ 1/6

= 21/10 ×6/1

= 63/5

= 12.6 miles per hour

Therefore, the speed for the given distance and time is 12.6 miles per hour.
