Answer:
$1410
Step-by-step explanation:
Hyan has $1240 saved, which is equal to 2/3 of the down-payment, plus an additional $300
$1240-$300= $940
$940 is equal to 2/3 of the payment, in other words, it's two 1/3 payments, so we can split $940 into two to see how much is equal to 1/3 of the payment.
$940/2= $470 = 1/3
Three 1/3 equal 1 whole so we multiply $470 by 3 to find the amount of the whole payment
$470x3= $1410

1.A term that is a known number without variables. is called?
Answer:
constants
Step-by-step explanation:
Constants are the terms in the algebraic expression that contain only numbers. That is, they're the terms without variables. We call them constants because their value never changes, since there are no variables in the term that can change its value.
Samuel orders four DVDs from an online music store. Each DVD costs $9.32. He has a 25% discount code,
and sales tax is 6.5%. Round sales tax amounts to the nearest cent. What is the total cost of his order?
The total cost of Samuel's order is $

24. Marissa needs 2 2/3yards of ribbon for a wall-hanging she wants to make. She has 2 3/4 yards. Does she have enough ribbon? Explain.
Answer:
no
Step-by-step explanation:
because she just has one less so all she need to do is get one more and then she'd have enough
Answer:
yes, she has enough ribbon.
Step-by-step explanation:
find common denominator for 2 2/3 and 2 3/4 which is 12
2 2/3 becomes 2 8/12 [what she needs]
2 3/4 becomes 2 9/12 [what she has]
she has 1/12 more than she needs.
What is an equation of the line that passes through the point (2,-3) and is perpendicular to the line 2x+5y=10?
===============================================
Explanation:
Consider the standard form Ax+By = C
Anything perpendicular to this is Bx-Ay = D. We swapped the positions of A and B, and changed the plus sign to a minus. This will ensure we get a negative reciprocal slope needed for the perpendicular line. The slope of the first line is -B/A, while the slope of the second line is A/B. The two slopes multiply to -1 assuming neither A nor B are zero.
Also, I've introduced the constant D. There may be cases when C = D, but that isn't always the case.
The given equation is 2x+5y = 10. This tells us A = 2, B = 5, C = 10.
The perpendicular line will be of the form 5x-2y = D, based on the template I mentioned above.
Plug the coordinates (2,-3) into 5x-2y = D to find the value of D
5x-2y = D
5(2)-2(-3) = D
10+6 = D
16 = D
D = 16
So 5x-2y = D updates to 5x-2y = 16
Therefore, 5x-2y = 16 is perpendicular to the original line, and this new line goes through (2,-3)

Is 5/4 a solution to the problem: 3(+9)=4−7+7.
Answer:
No the soultion is not equal to 1 1/4
The solution to the given question is either 6 3/4 or 4 /27
Step-by-step explanation:
Let
3(+9)=(4−7+7)x
27 = 4x
x= 27/4
x= 6 3/4 is the answer
or
Let
3(+9) x=(4−7+7)
27x = 4
x= 4/27
The plus sign inside the bracket indicates that 3 is multiplied with positive nine and -7 and +7 are cancelled and 4 is left behind.
If x is on the left side the answer will be 6 3/4 and if it is on the right side the answer is 4/27 .
In both cases the answer is not equal to 5/4 .
5/4 means 1 1/4 which is not equal to either 6 3/4 or 4/27

A movie club is having a new-member sale, so Mindy signs up. The equation
-0.4x + 0.05y - 1.25 = 0 relates y, the total cost, and x, the number of
months. What is the y-intercept of the line represented by the equation?
A -1.25
B 0.05
c 8
D 25
Greg chose c as the correct answer.how might he have gotten the answer
Answer:
D is the correct choice
Step-by-step explanation:
To get the y-intercept, we write the equation in the standard form
The standard form is ;
y = mx + b
So we have to rewrite the equation this very form
Thus, we have that;
0.05y = 0.4x + 1.25
we simply isolate the y value
To do this, we divide through by 0.05 and the y-intercept value will be ;
1.25/0.05 = 25

How are the properties of exponents used to rewrite expressions?
Answer: The five exponent properties are
Product of Powers: When you are multiplying like terms with exponents, use the product of powers rule as a shortcut to finding the answer. It states that when you are multiplying two terms that have the same base, just add their exponents to find your answer.
Power to a Power: When raising a power to a power in an exponential expression, you find the new power by multiplying the two powers together. ... Then multiply the two expressions together. You get to see multiplying exponents (raising a power to a power) and adding exponents (multiplying same bases).
Quotient of Powers: When you are dividing like terms with exponents, use the Quotient of Powers Rule to simplify the problem. This rule states that when you are dividing terms that have the same base, just subtract their exponents to find your answer. The key is to only subtract those exponents whose bases are the same.
Power of a Product: The Power of a Product rule is another way to simplify exponents. When you have a number or variable raised to a power, it is called the base, while the superscript number, or the number after the '^' mark, is called the exponent or power.
Power of a Quotient: The Power of a Quotient rule is another way you can simplify an algebraic expression with exponents. When you have a number or variable raised to a power, the number (or variable) is called the base, while the superscript number is called the exponent or power
You can use these any way you want to rewrite an equation.

15 meters higher from the start of the ride are they after these 20 seconds.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Let's say they were initially at level x from ground
After the first 20 seconds.
Level = x + 30
Then plunges down
So,
Level = x + 30 - 30 = x level.
Now 15-meter rise
So,
Level = x + 15
Now level from initial = (x + 15) - x = 15 meter.
Hence "15 meters higher from the start of the ride are they after these 20 seconds".

A bag contains 3 blue, 4 red and 3 yellow marbles. How many blue marbles must be added to the bag for it to contain 75% blue marbles?
Answer:
18
Step-by-step explanation:
Note that 75% = 75/100 = 3/4, so 3/4 of the marbles must be blue. Let x be amount of blue marbles added. We can write an equation using this.
75% = 3/4 = (3 + x blue marbles)/(3 + 4 + 3 + x total marbles) = (3+x)/(10+x)
Multiplying by 4(10 + x) on both sides:
3(10 + x) = 4(3+x)
30 + 3x = 12 + 4x
18 = x
Therefore, we must add 18 blue marbles for 75% of the marbles to be blue.

Fencing How much fencing is required to enclose a circular garden whose radius is 28 m? Use 3.14 for . About nothing m of fencing is required to enclose the circular garden. (Type an integer or decimal rounded to the nearest hundredth as needed.)
Answer:
175.84 m
Step-by-step explanation:
Given that:
A circular garden which has a radius of 28 m.
[tex]\pi[/tex] = 3.14
To find:
The fencing required to enclose the circular garden ?
Solution:
Here, we are given a circle and its radius.
We are required to find the perimeter of the circle in order to find the fencing required to enclose the circular garden..
Formula for finding the perimeter of a circle is:
Perimeter = [tex]2\pi r[/tex]
where [tex]r[/tex] is the radius of the circle.
Using the given values in the formula:
Perimeter = [tex]2\times 3.14 \times 28[/tex] = 175.84 m
Therefore, 175.84 m of fencing is required.
