Find area of triangle 24cm by 7cm
Answer:
168
Step-by-step explanation:
24cm by 7
= L x W
= 24 x 7
A = 168
Answer:
84 cm²
Step-by-step explanation:
The fromula for the area of a triangle is:
[tex]A=\frac{hb}{2}[/tex]
h - height
b - base
We are given the measurements of 24cm and 7 cm.
[tex]A=\frac{7*24}{2}\\\\A=\frac{168}{2}\\\\\boxed{A=84}[/tex]
The area of the triangle should be 84 cm².
Hope this helps.
Xavier claims that the number of text messages he sends is proportional to the amount he owes on his monthly phone bill. He has listed the number of text messages sent and the amount he owed for a few months: January: 300 text messages sent; $15.00 owed February: 314 text messages sent; $15.70 owed March: 486 text messages sent; $24.30 owed April: 205 text messages sent; $10.25 owed Which of the following methods would help Xavier prove his claim? Select all that apply.
Answer:
Xavier could plot data points based on the number of text messages sent in each month and the amount owed to create a straight line on the graph starting at (0, 0.05).
Xavier could create a table listing the number of text messages sent in each of the months listed and the amount he owed for those months to test for equivalent ratios.

What is the value of q in the solution to this system of equations?
2m-5q=8
4m+2q=64
A.4
B.6
C.9
D.14
Answer:
4
Step-by-step explanation:
M,q 14,4
The value of q in the system of equations 2m-5q=8 and 4m+2q=64 is 4 thus option (A) is correct.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
As per the given system of equations,
2m-5q=8
4m+2q=64
Multiply by 2 into the equation 2m - 5q = 8
4m - 10q = 16
Subtract 4m - 10q = 16 by 4m+2q=64
-10 - 2q = 16 - 64
-12q = -48
q = 4
Hence"The value of q in the system of equations 2m-5q=8 and 4m+2q=64 is 4".

Please do number 14 for me. (Show work)
Answer:
A
Step-by-step explanation:
3x+h=180
h=180-3x
x+15+x+15+180-3x=180
-x+210=180
-x= -30
x=30
Now that we know that x=30 we can easily figure out the values of the other angles

What is the area of a parallelogram that has a base of 12 inches and a height of 8 inches?
Question 1 options:
96 square inches
1.5 square inches
20 square inches
Answer:
96 square inches
Step-by-step explanation:
Given in a parallelogram
base (b) = 12 inches
height (h) = 8 inches
Now
Area of parallelogram
= b * h
= 12 * 8
= 96 square inches
Hope it will help :)
Answer:
96
Step-by-step explanation:
Area= base x height
= 12 x 8
= 96
Since Area of parallelogram is base into height

Line segment t and line segment r are parallel. Both line segments are reflected across the y–axis to form line segments t' and r'. . What is the distance, in units, between line segmentst' and r'? Select ONE correct answer.
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, but I would show you how to answer it.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.
Reflection is the flipping of a figure about an axis. Reflection is a rigid transformation, that is it preserves the shape and size of the figure.
If the distance between Line segment t and line segment r is 5 units and then both line segments are reflected across the y–axis to form line segments t' and r'. The distance between the newly formed line segments t' and r' would still be 5 units

A bag contrains 3 red marbles and 4 blue . A marble is taken at random from the bag and replaced. Another marble is taken from the bag. Work out the probability that the two marbles taken from the back or the same color. Give your answer as a fraction
Answer:
4x-90(3)=50%m
Step-by-step explanation:
m= marbles (take note of my user name
Answer:
For each draw, the chances of getting a blue marble are 3 of 7; the chances of getting a red are 4 of 7.
The chances of drawing a blue on both draws is (3/7)^2 or 9/49, and the chances of getting red on both draws is (4/7)^2 or 16/49. But there are other possible outcomes which have to be considered to come to the correct answer.
There are 4 possible outcomes, as follows (although the chances of these outcomes are different):
Comb Chances
RR …….. 16/49
RB …….. 12/49
BR …….. 12/49
BB ……… 9/49
total …….. 49/49
So we can say that the chances of drawing red marbles on each draw are 16/49, and the chances of drawing blue ones on each draw are 9/49. But what about the chances of drawing either both red OR both blue?
I believe we can simply add the 2 probabilities together to come up with a probability of

Originally Answered: There is a bag filled with 3 blue and 4 red marbles. A marble is taken at random from the bag, the colour is noted and then it is replaced. Another marble is taken at random. What is the probability of getting 2 of the same colour?
Probability of two reds = 4/7 x 4/7 = 16/49 = 32.65%
Probability of two blues = 3/7 x 3/7 = 9/49
Probability of the same colour = 25 / 49 = 51.0 %
