▹ Answer
The correct answer is C. x = 375 sq ft y = 6,300 sq ft
▹ Step-by-Step Explanation
The ratio is 1:15 so...
x → 5,625
(Divide 5,625 by 15 since we have to find the x value meaning we have to do the inverse operation)
5,625 ÷ 15 = 375
420 → y
(Multiply 420 by 15 since we have to find the y value meaning we have to do multiplication)
420 × 15 = 6,300
Hope this helps!

Solve the equation -7 = y for x.
A. x= 4y - 28
B. x = y - 28
C. x = 4y + 28
D. x = 4y + 7
Answer:
x = 4y+28
Step-by-step explanation:
x/4 -7 = y
Solve for x
Add 7 to each side
x/4 -7+7 = y+7
x/4 = (y+7)
Multiply each side by 4
x/4*4 = 4(y+7)
x = 4y+28
Answer: X = 4y + 28
Step-by-step explanation: Our first step will be to solve for x.
To do this, we first add 7 to both sides.
This gives us x/4 = y + 7.
Now we want to multiply each side of the equation by 4.
So we get x/4(4) = 4(y + 7).
On the right, distribute the 4 through the parenthses!
Simplifying from here, we get x = 4y + 28.
So this is our final answer.
PLZ HELP, NEED ASAP Krista was assigned a homework problem that stated there were 45 stamps purchased for $18.75. Some stamps were 40 cents, and some stamps were 55 cents. To solve this problem, she wrote the system of equations that is shown below. 0.40 x + y = 45. x + 0.55 y = 18.75. Which explains the error that Krista made? Krista put 0.40 in the first equation meant for the number of stamps. Krista put 0.55 in the second equation meant for the value of stamps. Krista did not use the correct decimal to represent the total cost of the stamps. Krista mistakenly put 45 in the first equation when it should have been in the second equation.
Answer:
Krista put 0.40 in the first equation meant for the number of stamps.
Step-by-step explanation:
Krista's equation
0.40x+y=45
x+0.55y=18.75
The system of Equation should have been
x + y = 45 (1)
0.40x + 0.55y = 18.75 (2)
From (1)
x=45-y
Substitute x=45-y into (2)
0.40(45 - y) + 0.55y = 18.75
18 - 0.40y + 0.55y = 18.75
Collect like terms and you now have
0.55y - 0.40y = 18.75 - 18
0.15y = 0.75
Divide both sides of the equation by 0.15
y = 5
Substitute y=5 into (1)
x + y = 45
x+5=45
x=45-5
x=40
This shows that the stamps that cost 0.40 cents were 40 while those that cost 0.55 cents were 5 in number.
Krista's error:
Krista put 0.40 in the first equation meant for the number of stamps.
Answer: A, Krista put 0.40 in the first equation meant for the number of stamps.

The set of all real numbers x that satisfies 5 5x58 is given by the following interval notation:
[5,8]
The question is a True or False question
Answer:
True
Step-by-step explanation:
Given
5 ≤ x ≤ 8
Required
Is [5,8] the interval of the given range?
The interval given shows that the range of x begins at 5 and ends 8.
Start by splitting the interval to different inequalities.
1. 5 ≤ x
This implies that 5 is less than or EQUAL TO x;
The keyword needed here is EQUAL TO;
The fact that the inequality gives room for EQUALITY (=) means that the interval begins exactly at 5
2. x ≤ 8
This implies that x is less than or EQUAL TO 8;
Similarly, the keyword needed here is EQUAL TO;
The fact that this inequality gives room for EQUALITY (=) means that the interval ends exactly at 8
So, this implies that the range of values of 5 ≤ x ≤ 8 is 5, 6, 7, 8
And can be represented with [5,8]
So, the statement is true.

Irrational numbers have decimal expansions that neither terminate not repeatable
π = 3.1428.........
-4π =-12.5714..........
Answer:
D. Irrational
Step-by-step explanation:
First, let's calculate what -4π is.
-4π= -4*π= -12.5663706143....
Now, let's analyze the answer choices.
Whole numbers are the numbers 1,2,3,4,5...
Integers are like whole numbers, but negatives are also included.
Rational numbers are numbers that can be written as fractions, or have repeating/terminating decimals.
Irrational numbers cannot be written as fractions, do not repeat and do not terminate.
-12.5663706143... doesn't repeat or terminate, therefore it must be irrational.

Answer:
x° = 62
Step-by-step explanation:
The vertical angle to 28 degrees is 28 degrees in size.
The vertical angle to 90 degrees is 90 degrees in size.
Angles in a circle add up to 360 degrees.
x + 28 + 152 + 28 + 90 = 360
x + 298 = 360
x = 360 - 298
x = 62
Angle x is 62 degrees in size.

If x is the number of odd integers between 10
and 51, and y is the number of even integers
between 10 and 51, what is the value of x + y?
(A) 39
(B) 40
(C) 41
(D) 48
Answer:
C. 41
Step-by-step explanation:
We want to find the number of odd integers from 10 to 51.
The first odd integer from 10 to 51 is 11; the second is 13; the third is 15; and so on until 51. So, our list looks like this:
11, 13, 15, ... , 51
We need to figure out how many numbers there are. Let's add 1 to all of them:
11 + 1, 13 + 1, 15 + 1, ... 51 + 1
12, 14, 16, ... , 52
Now, let's divide by 2:
12/2, 14/2, 16/2, ... 52/2
6, 7, 8, ... , 26
Finally, subtract 5 from them:
6 - 5, 7 - 5, 8 - 5, ... , 26 - 5
1, 2, 3, ... , 21
There are 21 odd integers, so x = 21.
The even integers from 10 to 51 start with 12, 14. They end with 50. So, we have:
12, 14, ... 50
Let's use a similar method as above. Divide by 2:
12/2, 14/2, ... , 50/2
6, 7, ... , 25
Subtract 5:
6 - 5, 7 - 5, ... , 25 - 5
1, 2, 3, ... , 20
There are 20 even integers, so y = 20.
Then, x + y = 21 + 20 = 41.
The answer is thus C.

HELP SABRINA ;) ?!!!
Answer:
d) Vessels that are any length
Step-by-step explanation:
MSDs can be defined fully as Marine
Sanitation Devices. Marine Sanitation Devices are devices in the shape of a tank that is used for storing and treating of waste materials when marine vessels e.g. boats are on sea.
It is very inappropriate, unhygienic and illegal to dump waste materials at sea because this could cause harm to the aquatic life forms at sea. This is the reason why a marine sanitation device is required.
There are three types of MSDs
a) Type I
b) Type II
c) Type III
Marine Sanitation Devices are classified into types based on
1) The length of the vessels in which that are installed on.
2. The method for treating or breaking down the waste materials in the devices.
In the question above, the TYPE III MARINE SANITATION DEVICES CAN BE INSTALLED ON VESSELS THAT ARE ANY LENGTH.
This is because the Type III Marine Sanitation Devices are devices that stops the discharge or expelling of waste materials e.g sewage (whether have been treated or untreated) into the sea.
These type III MSDs is consists mainly of a tank used for holding and storing the waste materials. In this tank as well as other types of methods used for treating the waste which the includes incineration, composting e.t.c. may be found in the tank as well. Even after treating the waste in a Type III MSD, it can't be expelled into the sea , it can only be transferred to the Water Treatment Facility when the marine vessel comes to the seaport for more treatment and appropriate disposal.

How many 4-digit numbers divisible by 5, all of the digits of which are odd, are there?
Answer: 125
Step-by-step explanation:
For any number to be divisible by 5 it must end in either 0 or 5, thus for a 4 digit odd number it should end with 5 eg.1005,1015,1055 etc.
The exact number of 4 digit odd nos divisible by 5 can be calculated by using Principle of counting:
Therefore, no of possible numbers are: 5x5x5x1=125 numbers
