Answer:
The fraction of the work that are drawings is [tex]\frac{7}{20}[/tex]
Step-by-step explanation:
we have that
100%=100/100=1
we know that
The sum of the fractions of the works must be equal to 1
Let
x -----> the fraction of the work that are drawings
so
[tex]1=\frac{1}{4}+\frac{2}{5}+x[/tex]
Solve for x
[tex]1=\frac{13}{20}+x[/tex]
Subtract 13/30 both sides
[tex]x=1-\frac{13}{20}[/tex]
[tex]x=\frac{7}{20}[/tex]
Bev scored 540 points . This was 158 points more then Ike scored . How many points did Ike score
For this case we have to:
x: Variable that represents the points scored by Bev
y: Variable that represents the points scored by Ike
According to the data we have:
[tex]x = 540\\x = y + 158[/tex]
We substitute the first equation in the second one:
[tex]540 = y + 158[/tex]
We clear the variable "y":
[tex]y = 540-158\\y = 382[/tex]
So, Ike scored 382 points.
Answer:
Ike scored 382 points.
2 step equations that equal 18
Answer:
(2x6)+6
2x6=12
12+6=18
Final answer:
Two-step equations that equal 18 can be solved by performing two operations to isolate the variable, such as subtracting and then dividing, or adding and then dividing.
Explanation:
A student is asking for examples of two-step equations that result in an answer of 18. Two-step equations involve performing two operations to solve for the unknown variable. For instance, a simple two-step equation could be x/2 + 5 = 14, where you would first subtract 5 from both sides to get x/2 = 9, and then multiply both sides by 2 to find x = 18.
Another example could be 2x - 4 = 32. To solve this equation, you would first add 4 to both sides, resulting in 2x = 36, and then divide both sides by 2 to get x = 18.
These examples help students understand how to manipulate equations using addition, subtraction, multiplication, or division to isolate the variable and solve the equation.

To make orange paint, Roger next 5/8 cup of red paint to his cup of yellow paint. He really likes of the resulting color and wants to make a large batch of the orange paint. How much yellow paint is needed to mix with one cup of red paint?
Answer:
It is needed [tex]\frac{8}{5}[/tex] cups of yellow paint to mix with one cup
of red paint
Step-by-step explanation:
* Lets explain how to solve the problem
- To make the orange pint, Roger mixed 5/8 cup of red paint to one
cup of yellow paint
∴ The ratio of red paint to yellow paint is 5/8 : 1
- Lets simplify it by multiplying the two terms of the ratio by 8
∵ [tex]\frac{5}{8}(8):1(8)[/tex]
∴ The ratio of red paint : yellow paint = 5 : 8
∴ For every 5 cups of red paint we need 8 cups of yellow paint to
make the orange paint
- We need to know how many yellow paint is needed to mix with
one cup of red paint
∵ red paint : yellow paint
5 : 8
1 : ?
- By using cross multiplication we can find the number of yellow cups
∴ The number of the yellow cups = [tex]\frac{1*8}{5}=\frac{8}{5}[/tex]
∴ It is needed [tex]\frac{8}{5}[/tex] cups of yellow paint to mix with one
cup of red paint

In Troy's toy bin there are 14 red blocks. There are 6 more yellow blocks than red blocks. There are 2 more blue blocks than red blocks. How many blocks are there in all?
The total number of blocks in Troy's toy bin is 50, which is the sum of 14 red blocks, 20 yellow blocks, and 16 blue blocks.
Explanation:To solve the problem regarding Troy's toy bin, we need to use basic arithmetic to calculate the total number of blocks of each color and then add them together to find the total number of blocks in the bin.
Troy has 14 red blocks, so let's represent the number of red blocks as R = 14. It's mentioned that there are 6 more yellow blocks than red blocks, which means the number of yellow blocks Y = R + 6 = 14 + 6 = 20.
The problem states that there are 2 more blue blocks than red blocks, so the number of blue blocks B = R + 2 = 14 + 2 = 16.
Now, to find the total number of blocks in the bin, we simply add the numbers of red, yellow, and blue blocks:
Total blocks = R + Y + B = 14 + 20 + 16 = 50.
Therefore, there are 50 blocks in Troy's toy bin in all.
how do i rearrange f-ex=g-hx to get x?
Answer:
x = [tex]\frac{g-f}{h-e}[/tex]
Step-by-step explanation:
Given
f - ex = g - hx
Collect the terms in x on the left side by adding hx to both sides
hx - ex + f = g ( subtract f from both sides )
hx - ex = g - f ← factor out x on the left side
x(h - e) = g - f ← divide both sides by (h - e)
x = [tex]\frac{g-f}{h-e}[/tex]

If there are 400 students going on a trip, how many buses are need for all of the students to attend?
How many empty seats will be on the last (not full) bus?
Answer:
10, there will be 20 left open
Step-by-step explanation:
if each bus holds 42 students and there are 400 going then you need to divide 400 by 42, and then round up, to find how many seats will be left open, you take the answer and then multiply it by 42 and then subtract 400.

Triangle FGH is reflected across a vertical line to produce ABC. Which statement is true
a. The perimeter of triangle FGH is equal to the perimeter of triangle ABC.
b. The length of side BC is equal to the length of side FG
c. The length of side AB is equal to the length of side FH.
d. The length of side AC is equal to the length of side FG.
Answer:
answer is a
Step-by-step explanation:
answer would be a because a reflection does not change the size or shape of any figure
A reflection of a shape maintains its size and shape, changing only its position and orientation. Thus, the perimeters and corresponding side lengths of reflected triangles FGH and ABC are equal.
Explanation:When a shape is reflected across a line, its shape and size remain the same, although its orientation and position may change. Therefore, a reflection is a type of transformation called an isometry, also known as a congruence transformation. In the case of triangle FGH being reflected to form triangle ABC:
The perimeter of triangle FGH is equal to the perimeter of triangle ABC. This is because the lengths of the sides remain the same under a reflection.The length of side BC is equal to the length of side GH, assuming that BC corresponds to GH in the reflection.The length of side AB is equal to the length of side FG, assuming that AB corresponds to FG in the reflection.The length of side AC is equal to the length of side FH, assuming that AC corresponds to FH in the reflection.Learn more about Reflection of Triangles here:https://brainly.com/question/28097210

This year a small business had a total revenue of $26,00 if this is 33% more than their total revenue the previous year. what was their total revenue of the previous year
Answer:
19,549
Step-by-step explanation:
If 26,000 ( I'll assume you missed a 0) is 33% more than their total the previous year.
If the previous year is supposed to be 100%, this year is 100% + 33% = 133%
Using rule of three:
26,000 -> 133%
x -> 100%
x = 100/133 * 26,000 = 19,549
what is the sum of the complex numbers below? 4−7i and −3+5i
a −i
b 1+2i
c 3
d 1−2i
Answer:
d 1–2i
Step-by-step explanation:
(4–7i)+(–3+5i)=1–2i
The sum of the complex numbers 4−7i and −3+5i is obtained by adding the real parts and the imaginary parts separately. This gives a result of 1 - 2i.
Explanation:To find the sum of two complex numbers, you simply add the real parts together and the imaginary parts together separately.
So, you add the real parts (4 and -3), which equals 1, and the imaginary parts (-7i and 5i), which equals -2i.
Thus, the sum of the complex numbers 4−7i and −3+5i is 1 - 2i.

Liam bought a comic book and had $5 left. If he had a total of $8 walking into the store, how much did he spend on the comic book?
Liam used the equation 5x=8 to model the problem. He said that x represents the amount of money he spent. Liam said that the solution, x=1.6, means that he spent $1.60. Is he correct? Why or why not? If he is incorrect find the correct answer showing your work.
Pls Help Me
Answer:
Liam is incorrect
He spent $3 on the comic book
Step-by-step explanation:
Let
x -----> represents the amount of money he spent
we know that
The amount of money he spent plus the money he had left must be equal to the money he had when he walked into the store.
so
The linear equation that represent this problem is
x+5=8
solve for x
subtract 5 both sides
x=8-5=$3
therefore
Liam is incorrect
He spent $3 on the comic book
point O lies in the interior of angle MNP. if the measure of MNO is x^2 + 10x, the measure of ONP is x^2 - 2x , and the measure of MNP is 3x^2 + 12, find the value of x. then find the measure of ONP
Answer:
x = 6; ∠ONP = 24°
Step-by-step explanation:
1. Find the value of x
[tex]\begin{array}{rcl}\angle MNP & = & \angle MNO + \angle ONP\\3x^{2} + 12 & = & x^{2} + 10x + x^{2} - 2x\\3x^{2} + 12 & = & 2x^{2} + 8x\\x^{2} + 12 & = & 8x\\x^{2} -8x + 12 & = & 0\\(x - 2)(x - 6) & = & 0\\\end{array}[/tex]
[tex]x = 2 \text{ or }x = 6[/tex]
2. Find the measures of the angles
(a) x = 2
∠ ONP = x² - 2x = 2² - 2(2) = 4 - 4 = 0
This answer does not make sense because O lies in the interior of ∠MNP.
We disregard x = 2.
(b) x = 6
∠ ONP = x² - 2x = 6² - 2(6) = 36 - 12 = 24
If f(n) = n2 - 2n, which of the following options are correct? Select all that apply. f(2) = 0 f(1) = 3 f(-4) = 24 f(5) = 35 f(-2) = 0
Answer:
f(2)=0
f(-4)=24
Step-by-step explanation:
We are given
f(n)=n^2-2n
We are asked which of the following are true?
f(2)=0
f(1)=3
f(-4)=24
f(5)=35
f(-2)=0
Let's start with f(2)=0.
f(2)=2^2-2(2)
f(2)=4-4
f(2)=0
So f(2)=0 is true.
Moving on to f(1)=3.
f(1)=1^2-2(1)
f(1)=1-2
f(1)=-1
So f(1)=3 is false.
Now for f(-4)=24.
f(-4)=(-4)^2-2(-4)
f(-4)=16+8
f(-4)=24
So f(-4)=24 is true.
f(5)=35?
f(5)=5^2-2(5)
f(5)=25-10
f(5)=15
So f(5)=35 is false.
Finally f(-2)=0.
f(-2)=(-2)^2-2(-2)
f(-2)=4+4
f(-2)=8
So f(-2)=0 is false.
Answer:
The correct option are,
f(2) = 0, and f(-4) = 24
Step-by-step explanation:
Given function,
[tex]f(n) = n^2 - 2n[/tex]
By substituting n = 2,
[tex]f(2) = 2^2 - 2(2) = 4 - 4 = 0[/tex]
By substituting n = 1,
[tex]f(1) = 1^2 - 2(1) = 1 - 2 = -1[/tex]
By substituting n = -4,
[tex]f(-4) = (-4)^2 - 2(-4) = 16 + 8 = 24[/tex]
By substituting n = 5,
[tex]f(5) = (5)^2 - 2(5) = 25 - 10 = 15[/tex]
By substituting n = -2,
[tex]f(-2) = (-2)^2 - 2(-2) = 4 + 4= 8[/tex]
