Answer:
[tex]x=5\sqrt[3]{3}[/tex] or 7.21
Step-by-step explanation:
x³ = 375
You have to take the square root and have the index 3:
You have to have the index 3 because x is cubed and you have to get rid of the cubed sign since a normal square root is for when the exponent is 2:
[tex]\sqrt[3]{x^3} =\sqrt[3]{375} \\x=5\sqrt[3]{3}[/tex]
In decimal form (rounded to hundredths):
7.21
A triangle has three angles that measure 30 degrees, 70 degrees What is the value of x?
Answer:
x = 80
Step-by-step explanation:
Sum of all the angles of triangle = 180
30 + 70 + x = 180
100 + x = 180 {Subtract 100 from both sides}
x = 180 - 100
x = 80°

Find the volume of the figure. Round to the nearest tenth if necessary.
1 point
3.4 in
4.8 in
25
Answer: 34 in^3
Step-by-step explanation:
Surface area of triangle = 1/2 x 3.4 x 2.5 = 4.25
To find the volume of the prism, multiply the surface area of the triangle by length.
So 4.25 x 8 = 34 in^3

Answer:
D. PerpendicularStep-by-step explanation:
First answer A. Answer A is not even correct. Parallel are two or more lines that NEVER cross
Answer B is also not correct. Line segments are a line of specific length. These are two LINES. You can tell by the arrows on the edge of each line.
Both C and D can be correct. But the answer would be D. Here is why
Intersecting lines are two or more lines that cross. Yes these lines are crossing by perpendicular lines also cross. The difference is, intersecting lines can cross at any angle. Perpendicular lines have to cross at 90 degrees making 4 right corners.
What’s the length of a segment whose endpoints are (8,-6) and (-4,2)?
Answer:
Step-by-step explanation:
Imagine or draw a triangle with horizontal leg length 8 - (-4), or 12, and vertical leg length |-6 - 2|, or 8. Use the Pythagorean Theorem to find the length of the hypotenuse:
length of hypotenuse = +√(8² + 12²) = √208 = 4√13 (Answer A)
GHJU is a rhombus. how could you prove that <3~=<2? this doesn’t have to be a formal proof, just a basic outline of an augment. how would you approach this proof?
Answer:
Angle 3 is equal to Angle 2 because when you have a rhombus, the diagonals will always bisect the angles.

Daniel solves the equation 3(x+1)-5=3x-2 and states that it has no solution. Is he correct?
Explain why and why not.
Answer:
He is incorrect
Step-by-step explanation:
Given
3(x + 1) - 5 = 3x - 2 ← simplify left side
3x + 3 - 5 = 3x - 2
3x - 2 = 3x - 2
Since both sides are equal, then this indicates that the equation has infinite solutions.

Quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P′Q′R′S′. Which rule describes this transformation? F.(x, y) → (x — 5, y — 3) G.(x, y) → (x + 5, y + 3) H.(x, y) → (x — 3, y — 5) J.(x, y) → (x + 3, y + 5)
Answer:
G.(x, y) → (x+5, y+3)
Step-by-step explanation:
The rule would be (x+5, y+3) and the only one with that rule is G.

Step-by-step explanation:
find the highest exponent of each polynomials:
22=> 0 degree
-3x(equals to -3x^1) + 10=> 1st degree
5x^2 + 5x + 5=> 2nd degree
-x^3 + 3x^2 + 2x + 4=> 3rd degree
2x^4=> 4th degree
Show and explain how you would solve the following equation by graphing x - 2 = 5
Answer:
See below
Step-by-step explanation:
If you graphed x-2=5, you would see a vertical line crossing the point x=7, as shown in the graph because 7-2=5.
Select all the statements that describe the expression 5 + 2x. *
The expression represents 5 plus 2 plus x.
The expression represents 5 plus 2 times x
The expression represents 5 plus x plus x.
The expression represents 5 plus x times x.
The expression represents the sum of 5 and 2x
The expression represents the product of 5 and 2x.
What is the measure of angle z in this picture?
Answer:
z = 137 degrees
Step-by-step explanation:
Angle 43 and angle z make a straight line, which is 180 degrees
43+z = 180
Subtract 43 from each side
43+z-43 = 180-43
z =137

Solve for a. -4a - 2a – 7 = 11 a = [?]
Answer:
a = -7/17
Step-by-step explanation:
Add -4a to -2a
This makes -6a. Then you add 6a to the left to cancel it out, but you must also add 6a to the right of the =
Then you have -7 = 17a
Divide 17 from both sides and you have -7/17 = a

Mr. drew rides his motorcycle with a constant speed of 72 mi/hr. How far can he travel in 2 ½ hours?
Answer:
180
Step-by-step explanation:
take 72+72 +36 to get your answer .
Answer:
180 miles
Step-by-step explanation:
Assuming that the speed of the motorcycle is constant, the following equation, ([tex]speed * time = distance[/tex]) can be used to find the distance that a vehicle traveled when one is given the time and speed at which the vehicle operates. Substitute in these values, and solve,
[tex](72)*(2\frac{1}{2})\\\\= 72 * \frac{5}{2}\\\\= 180[/tex]
Miranda sold movie DVD’s for $12 and television DVD’s for $9 and has collected $1167 from the sales of both. The number of movies sold is 4 less than 3 times the number of television shows. How many movie DVD’s were sold, and how many television DVD’s were sold?
Answer:
number of be television be 27 and the number of movies would be 50
Step-by-step explanation:
The computation of the number of DVD sold and the number of television sold is shown below:
Let us assume the number of television be x
So, the number of movies would be (3x - 4)
Now according to the question the following equation is made
12(3x - 4) + 9x = $1167
36x - 48 + 9x = $1,167
45x = $1,215
x = 27
So, the number of be television be 27
And, the number of movies would be
= (3x - 4)
= 3(27) - 4
= 50
