What is 918 rounded to the nearst cm
Here we will tell you what 918 is rounded to the nearest ten and also show you what rules we used to get to the answer.
Remember, we did not necessarily round up or down, but to the ten that is nearest to 918.
First, 918 rounded to the nearest ten is:

Find the missing angle in the triangle.
Question 1 options:
A. 90°
B. 25°
C. 108°
D. 130°
Answer:
A. 90 degrees
Step-by-step explanation:
a triangle has a total of 180 degrees in all of its angles combined (excluding the outside angles).
61+29=90
180-90=90
Find the area of a regular pentagon with a side of 5cm round to nearest tenth
Answer:
43 cm^2
Step-by-step explanation:
tan 72/2 = 0.7265
0.7265 = 0.5(5)/h
h = 3.44
3.44 x 5 x 0.5 = 8.6
8.6 x 5 = 43 cm^2
This is for algebra 1

For all the values of x,
f(x)=2x^2 and g(x)=x+1
Solve fg(x)=gf(x)
Answer:
if f(g(x)) = g(f(x)), then x is equal to zero.
Step-by-step explanation:
given:
f(x) = 2x²
g(x) = x + 1
then:
f(g(x)) = 2(x + 1)²
g(f(x) = 2x² + 1
so if:
f(g(x)) = g(f(x))
then:
2(x + 1)² = 2x² + 1
2(x² + 2x + 1) = 2x² + 1
2x² + 2x + 1 = 2x² + 1
2x = 0
x = 0
One number is 4 more than another, and their sum is 60. What is the smaller number?
If x = the larger number and y = the smaller number, then which of the following systems could be used to solve the problem?
x + y = 60 and -x + y = 4
x + y = 60 and x + y = 4
x + y = 60 and x - y = 4
Unlimited Attempts Remain
Answer:
Step-by-step explanation:
The system is
x+y=60 and x-y=4
If we get the difference between the two equations above we get
x+y-x+y=60-4
2y=56
y=28

Answer:
Plane
Step-by-step explanation:
The definition of a Plane is "In mathematics, a plane is a flat, two-dimensional surface that extends infinitely far."
It couldn't be a Ray or a Line Segment because a Ray has 1 end point, and a Line Segment has 2.
It also couldn't be a Line because a Line is only 1 dimensional.
The answer has to be Plane.
Grace drew a triangle. Its sides were 6 mm. 7 mm and 11 mm.
It has one obtuse and two acute angles.
Complete the sentence to describe the triangle Grace drew.
Answer:
That would be an obtuse-scalene triangle.
Step-by-step explanation:
It is scalene because none of the sides are congruent. This means that none of the angles or sides are the same.

Rodrigo's math certificate is 20 centimeters tall and 27 centimeters wide. Rodrigo wants to put the certificate in a fancy frame that costs $1.57 per centimeter. How much will it cost to frame Rodrigo's math certificate?
Answer:
the cost that used to frame the math certificate is $847.80
Step-by-step explanation:
The computation of the cost that used to frame the math certificate is shown below:
= 27 wide × 20 tall × $1.57 per centimeter
= $847.80
Hence, the cost that used to frame the math certificate is $847.80
Determine whether the triangle is acute, right, or obtuse given the sides: 11, 14, 20
Answer:
317 < 400
The Sum of the squares of the smaller 2 sides (121 + 196 = 317) < longest side squared (400) So, it is an OBTUSE SCALENE TRIANGLE.

Step-by-step explanation:
Write all three forms (slope intercept, point slope and standard) of a line containing the points (4, -11/3) and (1/2, -29/6).
Answer:
See explanations below
Step-by-step explanation:
Slope intercept form of the equation is expressed as y = mx+b
m is the slope
b is the intercept
Given the coordinates (4, -11/3) and (1/2, -29/6)
Slope m = -29/6-(-11/3)÷(1/2-4)
m = (-29/6+11/3)÷(-7/2)
m = -29+22/6÷(-7/2)
m = -7/6÷(-7/2)
m = -7/6×2/-7
m = 2/6
m = 1/3
Get the intercept b
Substitute m= 1/3 and (4, -11/3) into y = MX+b
-11/3 = 1/3(4)+b
-11/3 = 4/3+b
b= -11/3-4/3
b= -15/3
b =-5
Get the required equation
y = 1/3 x -5 (slope-intercept form)
Point slope form of the equation is expressed as y-y0 = m(x-x0)
Substituting m = 1/3 and the point (4,-11/3)
x0 = 4
y0 = -11/3
y - (-11/3) = 1/3(x-4)
y+11/3 = 1/3(x-4) (point-slope form)
For standard format
Recall that y = 1/3x - 5
Multiply through by 3
3y = 1/3x(3)-5(3)
3y = x-15
3y-x = -15(standard form)

Answer: y = 0.6x + 5.8
what is an equationof the line that passes through the points (0,-7) and (-8,3) put your answer in fully reduced form pleaseee help me.. 15 points ?
Answer:
y = -5/4x - 7
Step-by-step explanation:
First, find the slope:
3 - -7 / -8 - 0 = -5/4
Put it in point slope form:
y + 7 = -5/4(x-0)
y + 7 = -5/4x
y = -5/4x - 7

-4y + 2= -2
whats Y?
Answer:
y = 1
Step-by-step explanation:
-4y + 2 = -2
-2 -2
-4y = -4
Then you divide both sides by -4..
-4y/-4 = -4/-4
So
y = 1
