375 fish are swimming in a school. First, 47 fish swim away. Then 116 more fish join the school. How many fish are in the school now? 2. Which operations will you use to find how many fish are in the school now? Explain. 3. Generalize Are there now more or less than 375 fish in the school? Explain how you know. 4. How many fish are in the school now?
Answer:
444
addition and subtraction
there are more fish in the school
the number of fishes that left the school is less than the number of fish that joined the school
Step-by-step explanation:
fishes that swam away = 375 - 47 = 328
fish that joined = 328 + 116 = 444
to determine the fish that swam away subtract. to determine the fish that joined, add.
116 is greater than 47. so there are more than 375 fish in the school
Which expression represents the product or x3+2x-1 and x4 - x3+3?
Answer:
4th option
Step-by-step explanation:
(x³ + 2x - 1)([tex]x^{4}[/tex] - x³ + 3)
Each term in the second factor is multiplied by each term in the first factor, that is
x³([tex]x^{4}[/tex] - x³ + 3) + 2x([tex]x^{4}[/tex] - x³ + 3) - 1 ([tex]x^{4}[/tex] - x³ + 3) ← distribute parenthesis

Answer:
DE ≈ 6.97
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos55° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{EF}{DE}[/tex] = [tex]\frac{4}{DE}[/tex] ( multiply both sides by DE )
DE × cos55° = 4 ( divide both sides by cos55° )
DE = [tex]\frac{4}{cos55}[/tex] ≈ 6.97 ( to the nearest hundredth )
An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 13 inches, and the length of the base is 8 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch
Answer:
12.2 inches
Step-by-step explanation:
An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 5 inches, and the length of the base is 2 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch.
The length of the sides of the isosceles triangle can be found from the
given altitude and the length of the base.
The perimeter of the triangle is approximately 35.2 inches.Reasons:
The given parameter are;
The triangle is an isosceles triangle
The altitude cuts the base into two
Length of the altitude, h = 13 inches
Length of the base of the triangle, l = 8 inches
Required:
Find the perimeter of the triangle.
Solution:
By using the Pythagorean theorem, we have;
Length of one of the isosceles sides of the triangle which is an hypotenuse
side of the right triangle formed by the altitude, R, is given as follows;
[tex]\displaystyle R = \mathbf{\sqrt{ h^2 + \left(\frac{l}{2} \right)^2}}[/tex]
Therefore;
[tex]\displaystyle R = \sqrt{ 13^2 + \left(\frac{8}{2} \right)^2} = \mathbf{ \sqrt{ 13^2 + 4^2}} =\sqrt{185}[/tex]
R = √(185) inches
Therefore, the length of the other hypotenuse side = R = √(185) inches
On the original triangle, the sides are; R, R, and l
Which gives;
The perimeter of the triangle, P = R + R + l = 2·R + l
Therefore;
P = 2 × √(185) + 8 ≈ 35.2
The perimeter of the triangle, P ≈ 35.2 inches.

Question: If 2cm represents 75 miles on a scale drawing. How long would a line segment be that represents 50 miles?
Answer:
1.33cm
Step-by-step explanation:
if 2cm is representing 75 miles, that means that .66 (repeating) is representative of 25 miles. This is because .66 (repeating) times 3 is equal to 2, and 25 times 3 is equal to 75. The reason 1.33cm would be equal to 50 miles is because if 25 miles is equal to .66, and 50/25 = 2, then you would have 2x.66 (repeating), to get 1.33.

A rectangle has a side length of 2x and a diagonal of 8x. What is the missing lenght?
Answer:
2x[tex]\sqrt{15}[/tex]
Step-by-step explanation:
we can use the Pythagorean Theorem to find the missing side (a):
a² + (2x)² = (8x)²
a² + 4x² = 64x²
a² = 60x²
a = √60x²
a = [tex]\sqrt{4}[/tex]·[tex]\sqrt{15}[/tex] · [tex]\sqrt{x^2}[/tex]
This can be simplified to be 2x[tex]\sqrt{15}[/tex]

Which relationship is true for the triangle based on the Law of Sines?
Answer:
We know the angle given refers to the length of the opposite side.
Given angle = 82 and the opposite side = 34 so part of the relationship is
sin 82 / 34 = sin ( ) / ( )
We are also given one side = 27 and that side is opposite angle at C
so that part of the relationship is sin C / 27
sin 82 / 34 = sin C / 27
A true relationship based on the Law of Sines was found in the given triangle.
In the given triangle
∠A=82°
Length of side in front of ∠A = 34
Length of side in front of ∠C = 27
What is sine law?According to sine law, in a triangle, ABC, if the sides in front of ∠A, ∠B, ∠C are a, b, c respectively then
[tex]\frac{SinA}{a} =\frac{SinB}{b} =\frac{SinC}{c}[/tex]
According to the sine law, the sides in front of angle A and angle C are 34 and 27 respectively.
So, [tex]\frac{Sin82}{34} =\frac{SinC}{27}[/tex]
Hence, a true relationship based on the Law of Sines was found in the given triangle.

The cereal box shown below is a rectangular prism.
Answer:
Surface area is found:
Surface Area = 1700 cm²
Step-by-step explanation:
(The cereal box is shown in the ATTACHMENT)
The surface area of a rectangular prism can be found by added the areas of all 6 sides of the rectangular prism.
L = length = 20 cm
H = height = 30 cm
W = Width = 5 cm
Side 1:
A(1) = L×H
A(1) = 20×30
A(1) = 600 cm²
Side 2:
As the measurements of the side at the back of side 1 has the same measurement of side 1. then:
A(2) = 600 cm²
Side 3:
A(3) = L×W
A(3) = 20×5
A(3) = 100 cm²
Side 4:
As the measurements of the side at the back of side 4 has the same measurement of side 4. then:
A(4) = 100 cm²
Side 5:
A(5) = H×W
A(5) = 30×5
A(5) = 150 cm²
Side 6:
As the measurements of the side at the back of side 5 has the same measurement of side 5. then:
A(6) = 150 cm²
Surface Area:
Adding areas of all the sides
A(1) + A(2) + A(3) +A(4) + A(5) + A(6) = 600 + 600 + 100 +100 + 150 +150
Surface Area = 1700 cm²

So far Monica has read 5/6 of book she has read the same number of pages each day for 5 days. What fraction of the book does Monica read each other ?
Answer:
Each day she has read 1/6 of the book.
Step-by-step explanation:
Monica has read 5/6 of book .
Each day she read the same number of pages for 5 days
Each day she read 5/6/5= 5/6*5= 1/6
Each day she has read 1/6 of the book.
So that in 5 days it makes
1/6+1/6+1/6+1/6+1/6= 5/6
Consider this equation. Cos(0) = 8/9 if 0 is an angle in quadrant IV, what is the value of tan(0)? I
Answer:
[tex]\displaystyle \tan(\theta)=-\frac{\sqrt{17}}{8}[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle \cos(\theta)=\frac{8}{9}[/tex]
Where θ is in QIV.
And we want to find the value of tan(θ).
Recall that cosine is the ratio of the adjacent side over the hypotenuse.
Therefore, the opposite side is:
[tex]o=\sqrt{9^2-8^2}=\sqrt{17}[/tex]
Next, in QIV, only cosine is positive: sine and tangent are both negative.
Tangent is the ratio of the opposite side to the adjacent. So:
[tex]\displaystyle \tan(\theta)=\frac{\text{opposite}}{\text{adjacent}}[/tex]
Substitute. Tangent is negative in QIV. Hence:
[tex]\displaystyle \tan(\theta)=-\frac{\sqrt{17}}{8}[/tex]

BE = 219º
Step-by-step explanation:
∠BFE is supplementary to ∠EFC
m∠BFE = 180 - 9
m∠BFE = 171º
--------------------------
The angle between two chords is equal to half the sum of the intercepted arcs:
∠BFE = (DC + BE)2
171 = (123 + BE)/2

The latest online craze is a new game, Khan on Seven. You get 100 points for playing the game. In addition, you get 50 points for each seven-letter word you make with the ten letters you receive. Sal wants to break the record, and he needs 18000 or more points to do so.
Write an inequality to determine the number of seven-letter words, w Sal could make to break the record.
Answer:
Answer: 50x+100\geq18,00050x+100≥18,000
Let w denotes a seven letter word which Sal will need to make to break the record.
Since you get 50 points for each seven-letter and 100 points for playing the game.
Then the total points earned by you by making w seven letters words will be:
50x+10050x+100
Since, Sal wants to break that record, and needs 18,000 points or more to do so.
Then , the required inequality will be :
50x+100\geq18,00050x+100≥18,000
