Answer: Two ratios that have the same value are called equivalent ratios. To find an equivalent ratio, multiply or divide both quantities by the same number. It is the same process as finding equivalent fractions.
Step-by-step explanation:
Answer:
We add up all elements of ratio then place smaller value and set as a fraction if both fractions are equal from 2 sets of ratios then we have equivalent ratios.
Example set of ratios we see 1:2 and 6:3 is equivalent
as 6:3 could be 6/9 just like 3/9 is and 3/9 is ratio equivalent shown can be shown 3/9 = 1/3
As 1:2 = 1/3 or 2/3 and its 1/3 thats shown in workings.

Which of the triangles shown are scalene triangles?
Answer:
Triangle D
Step-by-step explanation:
Triangle A is an isoceles because two of the sides are equal in length.
Triangle B is a right isoceles triangle because two of the sides are equal in length and there is a right angle.
Triangle C is an isoceles because two of the sides are equal in length.
Triangle D is a scalene triangle becasue none of its sides are the same length.

Answer:
2/3(3/4x-3/2) = 1/2x-1
(2x+1) - (x+3/2) = x - 1/2
Step-by-step explanation:
1) Distribute 2/3 to both 3/4x and -3/2
2/3(3/4x) = 6/12x which can be simplified as 1/2x
2/3(-3/2) = -6/6 which simplifies to -1
2/3(3/4x-3/2) = 1/2x-1
2) (2x+1) - (x+3/2) combine like terms
2x-x = x
1 - 3/2= 1- 1 1/2 ( change 3/2 into an improper fraction. 2 goes into 3 one time with one left over. Place the “leftover” back on top of the original denominator of 2)
1- 1 1/2 = -1/2, so
(2x+1) - (x+3/2) = x - 1/2

Segment CD will be parallel to segment C'D'. And the area and perimeter of the shape will remain the same. Then the correct options are B, D, and E.
What is a transformation of a shape?The translation does not change the shape and size of the geometry. But changes the location.
Suppose translating quadrilateral ABCD by 8 units to the left and 8 units down results in a new quadrilateral A'B'C'D'.
In the translation, the position is changed only but the dimension of the shape does not change.

Part B.) Determine the scale factor from the first map to the second map. Show your work. It may help you to “draw” out the two maps and label the trails and their corresponding lengths. (2 points)

Part C.) A landmark on the first map is a triangle with side lengths of 3 mm, 4 mm, and 5 mm. What are the side lengths of the triangle landmark on the second map? Show your work. It may help you to “draw” out the two maps and label the trails. (3 points)
Answer:
Scales are used on maps in the same way that they are used in plans.
A scale of 1 : 50 000 is used on many Ordnance Survey maps.
This means that 1 cm on the map represents an actual distance of 50 000 cm (or 500 m or 0.5 km).
Converting measurements on a map
We saw above that if a map has a scale of 1 : 50000, then 1 cm on the map is 50000 cm in real life.
(a) Imagine we have measured a distance as 3 cm on this map, and we want to find out how far this is in real life.
To work out the distance in real life, we need to multiply this length by 50000.
This gives 3 cm × 50000 = 150000 cm which is 1500 m or 1.5 km.
Alternatively, we could have just remembered that each 1 cm on the map is 0.5 km in real life.
Hence, 3 cm on the map must be 3 × 0.5 km = 1.5 km in real life.
(b) Now imagine we want to walk 4.5 km in real life, and we need to find out how far this is on the map.
To work out the distance on the map, we need to divide this length by 50000.
4.5 km = 4500 m = 450000 cm. Dividing 450000 cm by 50000 gives a distance on the map of 9 cm.
Alternatively, we could have just remembered that each 0.5 km in real life is 1 cm on the map.
If we divide 4.5 km by 0.5 km we get 9, so the distance on the map must be 9 cm.

Oscar spent two thirds hour each night doing homework for five nights this week. How many hours of homework did Oscar complete this week?
seven and one half hours
three and one third hours
two and one third hours
one and one fifth hours
Answer:
The answer is 7.5 hours.
Step-by-step explanation: This is because if he spent 2/3 of every night doing homework for five days then he would spend a lot more than 3 hours and the other answers are even below 3 so thats gotta be incorrect.
Hope this helps.
Answer:
The answer is three and one third hours
Step-by-step explanation:
If Oscar spent two thirds an hour for five nights doing homework, then we would have night one is two thirds, the next night he spent one and one third, the next night would be 2 hours total, then the next night would add another 2/3 making it 2 2/3, finally the last night is two thirds of an hour making it a total of 3 and 1/3 hours spent on homework that week.

*15 POINTS* Laura goes to a bank and opens a new account. She deposits $5,500. The bank pays 1.6% interest compounded annually on this account. Laura makes no additional deposits or withdrawals. Which amount is the closest to the account balance at the end of 4 years? $5,852.00 $5,860.53 $5,940.00 $5,954.31
Answer:
A) 5,852.00
Step-by-step explanation:
I=prt. I=(5,500)(0.016)(4) I=352.00 => 352+5,500=5,852
The amount is the closest to the account balance at the end of 4 years should be considered as the $5,860.53.
Calculation of the amount:Since the deposited amount is $5,500
The interest rate is 1.6%
And, the time period is 6 years
So, here the amount at the end of 4 years should be
= [tex]$5,500 \times (1 + 1.6\%)^{4[/tex]
= $5,860.53
Hence, the second option is correct.

To buy a car, Danny borrowed $16000 for 3 years at an annual simple interest rate of 9%. if it takes him 3 full years to pay off the loan, how much interest will he pay? Show your work.
Answer:
$4,320
Step-by-step explanation:
I equals PRT. I is the interest. P is the principal, amount borrowed. R is the rate, percent. T is the amount of time in years. Principal in this is 16,000. Rate is 9%, or 0.09. Time is 3 years. So 16,000 times 0.09 times 3 equals 4,320. That is the interest.
