What is the area of a triangle whose base measures 3.2 centimeters and whose height is 4.6 centimeters.
Answer:
7.36 cm²
Step-by-step explanation:
What is the area of a triangle whose base measures 3.2 centimeters and whose height is 4.6 centimeters.
The formula for the area of a triangle is given as:
1/2 × Base × Height
Base = 3.2 cm
Height = 4.6 cm
Hence,
Area of the triangle = 1/2 × 3.2 × 4.6
= 7.36 cm²
Answer to this equation 5x^2+2=7
Answer:
x=1
Step-by-step explanation:
Answer:
x= 1 and x= -1
Step-by-step explanation:
[tex]5x^{2} +2=7[/tex]
(subtract 2 from both sides)
[tex]5x^{2} =5[/tex]
(divide by 5 from both sides)
[tex]x^{2} =1[/tex]
(take the square root from both sides)
x=±√1
so,
x= 1
and
x= -1

What is the quotient of m^6 over 5 divided by 5 over m^2
Answer:
[tex]\frac{m^{6}}{5}[/tex] / [tex]\frac{5}{m^2}[/tex] = [tex]\frac{m^8}{25}[/tex]
Step-by-step explanation:
[tex]\frac{m^{6}}{5}[/tex] / [tex]\frac{5}{m^2}[/tex]
= [tex]\frac{m^{6}}{5}[/tex] * [tex]\frac{m^2}{5}[/tex]
= [tex]\frac{m^8}{25}[/tex]

The ratio 2 centimetres to 5 metres can be written in the form
1
:
n
.
Find the value of
n
.
Answer:
n = 250
Step-by-step explanation:
To express the ratio, the quantities must have the same measures
2 cm : 5 m
= 2 cm : 500 cm [ 1 m = 100 cm ]
Divide both parts by 2
= 1 : 250 → with n = 250

What are the next four terms of the arithmetic sequence 122, 111, 100, ...?
Answer:
89, 78, 67, 56
Step-by-step explanation:
The next four terms of the arithmetic sequence is
As we can see that from the given sequence that 11 is deducted from each following number
122, 111, 100, 89, 78, 67, 56
122, (122 - 11), (111 - 11)
So the above represent the next four terms
What is the range for the function below?
If BE = 2x + 2, BD = 5× - 3, and AE = 4× - 6, what are the values of x and AC?
Answer:
x = 7
AC = 44
Step-by-step explanation:
Find the diagram attached
According to the parallelogram,
BD = 2BE
5x-3 = 2(2x+2)
5x-3 = 4x+4
5x-4x = 4+3
x = 7
Hence the value of x is 7
Also AC = 2AE
AC = 2(4x-6)
AC = 8x - 12
AC = 8(7) - 12
AC= 56-12
AC = 44
Hence the measure of AC is 44
x - 12 = -48 *
pls help quick
Answer:
x = -36
Step-by-step explanation:
Add 12 to both sides
x - 12 + 12 = x
(12 cancels out)
-48 + 12 = -36
x = -36
What is an equation of the line that passes through the points (4, -6) and
(8,-4)?
Answer:
y = 1/2x - 8
Step-by-step explanation:
(4, -6) & (8, -4)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(-4 - (-6)) / (8 - 4)
Simplify the parentheses.
= (2) / (4)
Simplify the fraction.
2/4
= 1/2
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 1/2x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (8, -4). Plug in the x and y values into the x and y of the standard equation.
-4 = 1/2(8) + b
To find b, multiply the slope and the input of x(8)
-4 = 4 + b
Now, subtract 4 from both sides to isolate b.
-8 = b
Plug this into your standard equation.
y = 1/2x - 8
This is your equation.
Check this by plugging in the other point you have not checked yet (4, -6).
y = 1/2x - 8
-6 = 1/2(4) - 8
-6 = 2 - 8
-6 = -6
Your equation is correct.
Hope this helps!

Question in picture
Answer:
x=21
Step-by-step explanation:
17x + 50 should equal to 19x + 8
so,
50 - 8 = 42 it means 42 shoul equal to (19x - 17x) = 2x.
so if 2x = 42 = 2x/2 = 42/2 = x = 21...
Which equation can be solved
Answer: Choice B) 2x-60 = 180
===========================================================
Explanation:
A bit of the question got cut off. I'm assuming the full question reads "In this diagram, the measure of angle RQS is 60 degrees less than the measure of angle PQS"
The portion underlined is the part cut off where I'm making the assumption. If that assumption is correct, then we have
angle PQS = xangle RQS = x-60Those two adjacent angles form a straight line of 180 degrees
(anglePQS) + (angleRQS) = 180
(x) + (x-60) = 180
2x-60 = 180
which points to choice B as the answer.
Answer:
Step-by-step explanation:
∠RQS = x - 60°
∠RQS = 180° - x
x - 60° = 180° - x
2x - 60° = 180°
