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.

Step-by-step explanation:
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 is a mouse like grass in a meadow
A mouse and grass in a meadow are similar as they both play vital roles in the energy flow within a meadow ecosystem. Grass acts as a primary producer, capturing energy from the sun, while the mouse, as a herbivore, acts a primary consumer, eating the grass and moving energy up the chain.
A mouse and grass in a meadow can be seen as similar in the context of a biological ecosystem. In a meadow ecosystem, both play crucial roles.
The grass forms the primary producer layer of the food chain, as it harnesses energy from the sun to produce food via photosynthesis.
This provides the basic energy source for other members of the ecosystem. The mouse, on the other hand, is part of the primary consumer layer of the food chain.
As a herbivore, it consumes the grass for energy, thus transferring the energy obtained from the sun up the food chain. So, the similarity of the mouse and the grass in a meadow lies in their integral roles in the energy flow within an ecosystem.

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]

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

A rectangle has a length of 8.3cm and a perimeter of 22.4cm
Answer:
width = 2.9 cm
Step-by-step explanation:
Since there are two sides that equal to length on a rectangle, you double the length. Then, you subtract that number to find (width * 2). Then you divide that by 2 to get your answer (2.9 cm).
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

The upper boundary on x is 5. Divide this over each endpoint of the y inequality
5/0.25 = 20
5/4 = 1.25
we see that the first result 20 is largest
This means that the upper bound of x/y is 20.
Therefore b = 20.
----------------------------
The lower boundary on x is -4. Divide this over each endpoint of the y inequality
-4/0.25 = -16
-4/4 = -1
The result -16 is further to the left compared to -1, so therefore it is smaller.
The lower bound of x/y is -16.
This means a = -16.
----------------------------
We found that a = -16 and b = 20. Therefore, a+b = -16+20 = 4

Step-by-step explanation:
30-23 1/3=6 2/3
Answer: [tex]\frac{20}{3}\ minutes[/tex] or [tex]6 \frac{2}{3}\ minutes[/tex]
Step-by-step explanation:
For this exercise you can convert the mixed number to an improper fraction:
1. Multiply the whole number part by the denominator of the fraction.
2. Add the product obtained and the numerator of the fraction (This will be the new numerator).
3. The denominator does not change.
Then:
[tex]23\frac{1}{3}= \frac{(23*3)+1}{3}= \frac{70}{3}\ minutes[/tex]
You know that he had 30 minutes in time-out, he counted spots on the ceiling for [tex]\frac{70}{3}[/tex] minutes and the rest of the time he made faces at his stuffed tiger.
Then, in order to calculate the time Calvin spent making faces at his stuffed tiger, you need to subract 30 minutes and [tex]\frac{70}{3}[/tex] minutes:
[tex]30\ min-\frac{70}{3}=(\frac{3(30)-70}{3})=\frac{20}{3}\ minutes[/tex] or [tex]6 \frac{2}{3}\ minutes[/tex]

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
