Answers
Answer:
the future value is 4,080
Step-by-step explanation:
The computation of the future value under the simple interest is shown below:
As we know that
Future value = Present value × (1 + rate of interest × time period)
= 3,000 × (1 + 6 × 6%)
= 3,000 × (1 + 0.36)
= 3,000 × 1.36
= 4,080
Hence, the future value is 4,080

Answer:
(x, y, z) = (2, 31°, 60°)
Step-by-step explanation:
Opposite sides have the same length, so ...
x + 8 = 10
x = 2 . . . . . . . . subtract 8
__
Consecutive angles are supplementary, so ...
(3y +10°) +(2y +15°) = 180°
5y = 155° . . . . . . subtract 25°
y = 31° . . . . . . . .divide by 5

Opposite angles are congruent, so ...
z +17° = 2y +15°
z = 2y -2° = 2(31°) -2°
z = 60°

Answer:
D. The bank balance in John's saving account increases from Month 4-5
Step-by-step explanation:
Lets go with one answer at a time
It talks about the fact that there is not change from Month 1 to Month 2However, an entire $750 has changed therefore, option A would be incorrect.
This one also talks about the fact that there is no change from Month 2 to Month 3When in fact it has changed more than $250 downwards, so option B would be incorrect.
This one talks about the bank account decreasing from Month 3 to 4However, in that time period it stays the same therefore, option C would also be incorrect.
Now that should mean that D is the right answer, but, we should still check.
This talks about John's bank account increasing from Month 4-5Yes it does change upwards. It increases $750 again.
Therefore, your answer would be D. The bank balance in John's saving account increases from Month 4 to 5.
Susanna found a roll of fabric she wanted to use to make a pillow. The roll had of a yard of fabric left. Susanna needed of the remaining fabric. Which fraction represents how much fabric Susanna needed?
Answers
Answer:

Step-by-step explanation:
Susanna found a roll of fabric she want to use to make a pillow. The roll had 3/4 of a yard of fabric left. Suzanne need 1/3 of the remaining fabric. Which fraction represents how much fabric Susanna needed?
Yard of fabric left = 3/4 of a yard
Yards needed by Susanna = 1/3 of the remaining fabrics
= 1/3 of 3/4 of a yard
= 1/3 × 3/4
= 1/4 of a yard
Therefore Susanna needs 1/4 of a yard of fabrics
The fraction which represents how much fabric Susanna needed is 1/4 of a yard

You buy 1 box of dog food and 2 cans of cat food for $25. Your friend buys 2 boxes of dog food and 1 can of cat food for $26.
Answers
1a + 2b= 25
2a + 1b = 26
simultaneous equations!!
2a + 4b=50
2a + 1b = 26
subtract from each other
2a - 2a = 0
4b - 1b = 3b
50 - 26 = 24
3b = 24
b = $8
then sub into equation
1a + 2(8) = 25
25-16 = 9
a= $9
The cost of 1 box of dog food is $ 9 and cost of 1 can of cat food is $ 8
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of 1 box of dog food be = x
Let the cost of 1 can of cat food be = y
The cost of 1 box of dog food and 2 cans of cat food = $ 25
The cost of 2 boxes of dog food and 1 can of cat food = $ 26
So , the equation will be
1x + 2y = 25 be equation (1)
2x + 1y = 26 be equation (2)
Now , Multiply equation (1) by 2 , we get
2x + 4y = 50 be equation (3)
On Subtracting equation (2) from equation (3) , we get
3y = 24
Divide by 3 on both sides , we get
y = $ 8
Substituting the value of y in equation (1) , we get
x + 2 ( 8 ) = 25
x + 16 = 25
Subtracting 16 on both sides , we get
x = $ 9
Therefore , the value of x is $ 9 and value of y is $ 8
Hence , the cost of 1 box of dog food is $ 9 and the cost of 1 can of cat food is $ 8

1.4m:6m
Step-by-step explanation:
First let's covert 2m to cm, this will make it easier to split,
2m = 200cm
Then we add the ratio,
7 + 3 = 10
Then we divide by 200cm
200 ÷ 10 = 20
Then we multiply by the ratio,
20 x 7 = 140
20 x 3 = 60
Finally we convert back to meters!
