Step-by-step explanation:
Set up synthetic division, starting with x - 1 as the divisor, and then (from that) 1:
1 / 1 0 0 -1 The coefficients of x^2 and x are zero here.
1 1 1
--------------------------
1 1 1 0
Since the remainder is zero, 1 is a root and x - 1 is a factor of the original
x^3 - 1 = 0.

WILL REWARD BRAINIEST! A right rectangular container is 6 cm wide and 10 cm long and contains water to a depth of 7cm. A stone is placed in the water and the water rises 1.7 cm. Find the volume of the stone.
Answer:
102cm^3
Step-by-step explanation:
v=l×w×h
10x6x7=420 cm^3
the volume of water+stone=
10×6×(7+1.7)
522cm^3
522-420= 102cm^3
The solution is: the volume of the stone is : 102cm^3.
What is volume?In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
Here, we have,
Given that,
A right rectangular container is 6 cm wide and 10 cm long and contains water to a depth of 7cm. A stone is placed in the water and the water rises 1.7 cm.
We know that,
volume is :
v=l×w×h
so, we get,
10x6x7=420 cm^3
the volume of water+stone=
10×6×(7+1.7)
522cm^3
522-420= 102cm^3.
Hence, The solution is: the volume of the stone is : 102cm^3.

At the beginning of 5th grade, Stephen was 48 inches tall. At the beginning of 8th grade he was 65 inches tall.
What is the percent of increase of Stephen's height?
A. 17.00%
B. 26. 15%
C. 35.42%
D. 73.85%
Answer:
35.42%
Step-by-step explanation:
Answer:
C. 35.42%
Step-by-step explanation:
65 - 48 = 17
Since he grew 17 inches, you must figure out what percentage 17 is of 48.
17/48 = 1/100 (represents decimal)
Cross multiply: 17 ⋅ 100 = 1700 and 48 ⋅ 1 = 48
Divide: 1700/ 48
= 35.41666666666667
Round to the nearest hundredth:
= 35.42

The diameter of a circle is 4 cm. Find its area to the nearest tenth.
Answer:
10 cm²
Step-by-step explanation:
The radius of this circle is half the diameter hence is 2cm
Area of a circle is pi multiplied by the squared radius, i.e
Area = πr²
= 22/7 × 2 × 2
= 12.57 cm²
The nearest 10th is 10

Based on the inscribed angle theorem, the measure of angle BED in the diagram given is: 57°.
What is the Inscribed Angle Theorem?The inscribed angle theorem states the measure of the inscribed angles subtended by the same arc are the same.
∠BCD and ∠BED are subtended by the same arc BD.
Therefore, based on the inscribed angle theorem, we have:

Abby wants to ride her bicycle more than 70 miles this week. On Monday, Abby rode her bicycle for 25 miles. Abby plants to ride the same number of miles in the next six days. Write an inequality that can be used to determine the number of miles, m, that Abby will ride her bicycle each day to achieve her goal.
Answer:
25d > 70
Step-by-step explanation:
Abby wants to ride her bicycle more than 70 miles this week.
More than = >
On Monday, Abby rode her bicycle for 25 miles. Abby plants to ride the same number of miles in the next six days.
Let the number of days of week she would ride her bike = d
On Monday = 25 miles
And the rest of the week = The same = 25 miles
The inequality is written as:
25d > 70

An angle measures 56° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
118, 62
Step-by-step explanation:
We can set a system of equations where x and y are the two angles and x is the larger one
x+y=180
x-y=56
If we subtract the second equation from the first, we get 2y=124, simplifying that, we get y=62. Plugging it into either equation, we get x=118. We can check that 118 is 56 larger than 62, which it is. Thus, x=118, y=62.

Which graph shows the solution to this system of inequalities? y>-1/3x+1 y>2x-3
Answer:
Graph A.
Step-by-step explanation:
We don't even have to analyze the inequalities. It tells us that y is supposed to be bigger than something and that y is supposed to be bigger than something else. That means that for both lines, the shaded region must be upwards. The only graph that conforms to that is graph A.
