Answer:
The length of side of cube ranges between 8cm and 9cm as the given surface area is acquired when length of side of cube is 8.07 cm
Option C is correct.
Step-by-step explanation:
If the surface area of a cube is 390 cm, then which best describes the length of the side of the cube?
Surface area of cube = 390 cm
The formula used to find surface area of cube is: [tex]Surface area = 6a^2[/tex]
where a is the length of side of cube.
If length of side of cube = 7 cm, the surface area of cube = 294 cm
If length of side of cube = 8 cm, the surface area of cube = 384 cm
Now, if length of side of cube = 8.07 cm (found using calculator, by putting different values in the formula)
We get surface area of cube = 390 cm
So, The length of side of cube ranges between 8cm and 9cm as the given surface area is acquired when length of side of cube is 8.07 cm
Option C is correct.

25 yd
37 yd
Answer:
27.3 yards
Step-by-step explanation:
Since this triangle is a right triangle, this can be solved using the equation:
a^2 + b^2 = c^2
c^2 is the side opposite to the right angle (37)
So, you need to change the equation to where it is set equal to b^2.
Subtract a^2 on both sides.
b^2 = c^2 - a^2
Now, plug in the numbers you have.
b^2 = 37^2 - 25^2
Simplify.
b^2 = 1369 - 625
b^2 = 744
Now, to find b, take the square root of 744.
√744 = 27.3

If the measure of angle 2 is 92 degrees and the measure of angle 4 is (one-half x) degrees, what is the value of x?
Answer: x = 184°
Step-by-step explanation: As we can see in the figure below, angles 2 and 4 are Vertical Angles, i.e., they are angles opposite each other when two lines cross. Vertical angles are always congruent.
Then,
m∠2 = m∠4
[tex]92=x.(\frac{1}{2})[/tex]
[tex]92=\frac{x}{2}[/tex]
Value of x is
[tex]x=92(2)[/tex]
x = 184
The value of x is 184°.

A piece of rope is 15.6 meters long. It is cut into 16 equal pieces. How long is each piece? Round your answer to the nearest tenth.
Answer:
1 m
Step-by-step explanation:
Given thta,
Length of a piece of rope = 15.6 m
It is cut into 16 equal pieces.
We need to find the length of each piece of rope.
Let the length of each piece is y m.
ATQ,
16 y = 15.6
⇒ y = 0.975
or
⇒ y = 1 m
Hence, the length of each piece is 1 m.

The width of a triangle is represented by 5 +2y. The length is twice as long as the width. What is the perimeter of the rectangle? Select all correct expressions.
Answer:
6(5+2y)
Step-by-step explanation:
We have width = w = 5+2y
L = length of the rectangle
Length has been give to be 2 x width
Width = w
So l = 2w
Perimeter of a rectangle = 2(l+w)
Since l = 2w, we have
2(2w+w)
= 2(3w)
= 6w
So since we already know w = 5+2y
We put this value into 6w
Then we will have this expression:
P = 6(5+2y)
2. P(-4, 2), (6, 4), R(11, -2), S(2, -3)
is this is parallelogram or not??

if 1+2x+1 = 10 , then -8x= ?
Answer:
- 8x = - 32
Step-by-step explanation:
Given
1 + 2x + 1 = 10, that is
2 + 2x = 10 ( subtract 2 from both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Then
- 8x = - 8 × 4 = - 32

GEOMETRY
*image is attached above*
Answer:
(-9.5, -4)
Step-by-step explanation:
Given the ratio a:b (a to b) of two segments formed by a point of partition, and the endpoints of the original segment, we can calculate the point of partition using this formula:
[tex]( \frac{a }{a + b} (x_{2} - x_{1}) + x_{1}, \frac{a}{a + b} (y_{2} - y_{1})+y_{1})[/tex].
Given two endpoints of the original segment
→ (-10, -8) [(x₁, y₁)] and (-8, 8) [(x₂, y₂)]
Along with the ratio of the two partitioned segments
→ 1 to 3 = 1:3 [a:b]
Formed by the point that partitions the original segment to create the two partitioned ones
→ (x?, y?)
We can apply this formula and understand how it was derived to figure out where the point of partition is.
Here is the substitution:
x₁ = -10
y₁ = -8
x₂ = -8
y₂ = 8
a = 1
b = 3
[tex]( \frac{a }{a + b} (x_{2} - x_{1}) + x_{1}, \frac{a}{a + b} (y_{2} - y_{1})+y_{1})[/tex]. →
[tex]( \frac{(1) }{(1) + (3)} ((-8) - (-10)) + (-10), \frac{(1)}{(1) + (3)} ((8) - (-8))+ (-8))[/tex] →
[tex]( \frac{1}{4} ((-8) - (-10)) + (-10), \frac{1}{4}((8) - (-8)) + (-8))[/tex] →
[tex]( \frac{1}{4} (2) + (-10), \frac{1}{4}(16) + (-8))[/tex] →
[tex]( (\frac{1}{2}) + (-10), (4) + (-8))[/tex] →
[tex]( (-\frac{19}{2}), (-4))[/tex] →
[tex]( -\frac{19}{2}, -4)[/tex] →

Adam exchanged British pounds for Swiss franc He changed £400 into 592 francs What was the exchange rate of British pounds to Swiss franc
Answer: 1 : 1.48
Step-by-step explanation:
Adam was able to change £400 into 592 francs which means that the British pound is stronger because it was able to buy more Swiss francs.
The exchange rate can be gotten using direct proportion:
400 : 592
1 : x
Cross multiply:
400x = 592
x = 592/400
x = 1.48
Exchange rate is:
= 1 : 1.48
