right-angled triangle is 12m² and the height is 6 metre.
Calculate the gradient and the area of the slanted surface
of the stone wall.
Answers
Answer:
14.42 m²
Step-by-step explanation:
h = 6 mS = 12 m²S = 1/2bh ⇒
b = 2S/h = 2*12/6 = 4 mGradient:
√(6²+4²) = √52 = 7.21 mArea of slanted surface:
7.21 m* 2 m = 14.42 m²
Answer:
14.42 m²

Kenji earned the test scores below in English class. 79, 91, 93, 85, 86, and 88 After his next test, his mean and median scores both change to 88. How much does he earn on this test?
Answers
Answer:
Step-by-step explanation:
We need to find what number he got on the test.
We know he got a bigger number than 88.
79+85+86+88+91+93+x.
Let's substitute x for 94.
79+85+86+88+91+93+94/2 = 88.
Since any other number thats near 94 doesn't equal 88, we know that this is exactly the right answer.

8. Find the equation of a line in slope intercept form that is parallel to the line y = -2x - 3 that goes
through the point (2, 1).
Work:
Answer:
Answers
Step-by-step explanation:
Hey there!!
To solve this type of question, use these steps.
Find these 1st equation by using one point formula of point.After this from equation 2 find slope, by comparing it with y= mx + c if it is in slope intercept form. Then, as per the conditions of parallel lines, use m1=m2, then put the value of m1 in equation 1st.Then simplify them.So, let's work with these steps.
Now,
The equation of a st.line passing through point (2,1) is,
[tex](y - y1) = m1(x - x1)[/tex]
Put all values.
[tex](y - 1) = m1(x - 2)[/tex]
It is the 1st equation.
Another equation is,
y = -2x -3.......(ii)
Comparing the equation with y = mx+c.
Therefore, from equation (ii)
m2 = -2
Now, as per condition of parallel lines,
m1=m2= -2
Putting the value of m1 in equation 1st.
[tex](y - 1) = - 2(x - 2)[/tex]
y - 1 = -2x + 4
y = -2x +5.
Therefore, the equation is y = -2x +5.

PLEASE HELP ME!!!!!!!
Answers
Answer:
There's two ways to solve this.
Step-by-step explanation:
First way:
Let's divide the width and length by 2.3.
46÷2.3=20
69÷2.3=30
20×30
600 ft²
Second Way:
Let's find the area of the actual room.
46×69
3,174 ft²
Let's find the scale drawing squared.
2.3²=5.29
3,174÷5.29

B. p varies inversely as r
Step-by-step explanation:
Since, p varies directly as q
[tex] \therefore p\:\:\alpha \:\:q\\
\therefore p= kq.. (k = constant)... (1)\\
[/tex]
Since, q varies inversely as r
[tex] \therefore q\:\:\alpha \:\:\frac{1}{r} \\
\therefore q= \frac{k}{r} .. (k = constant)... (2)\\
[/tex]
From equations (1) & (2)
[tex] p = k\times \frac{k}{r}\\
p = \frac{k^2}{r}\\
p\:\:\alpha \:\: \frac{1}{r}\\
[/tex]
Hence, p varies inversely as r.

Which relation is also a function?
Answers
Answer:
Step-by-step explanation:
A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y. That is, given an element x in X, there is only one element in Y that x is related to. For example, consider the following sets X and Y.
When we say about relation is a function
The given table relation is not a function
the graph relation is not a function
Given :
A relation is a function when all x values has exactly only one y value .
Each input has only one output for a function .
When x values are repeated then we can say that there is two output .
So that is not a function .
In the given table, we have x=5 repeated twice .
when x=5 there are two outputs [tex]-3 and -2[/tex]
for x=5, there are two outputs.
The given table relation is not a function
Now we consider the graph
When x=2 , there are 2 y values [tex]-3 \; and \; -4[/tex]
So input 2 has two output values
Hence , the graph relation is not a function

A ship must be unloaded by two cranes in 12 hours. Both cranes worked for 8 hours and then one of them broke. The rest of the work was done by the other crane in 7 hours. How long would each crane take to do the entire job if it was working alone? Thank you!
Answers
Answer:
6 hours
Step-by-step explanation:
8 hours x 2 cranes = 16 hours of total work
After one broke
7 hours x 1 crane = 7 hours of total work
16 + 7 = 23 hours
It would take 23 hours for one crane to do the whole job.

The diameter of a circle is 7 in. Find its area to the nearest tenth.
Answers
D = r • 2
R = D/2
7/2 = 3.5
R = 3.5
A = πr^2
A = 3.14 • 3.5^2
A = 3.14 • 12.25
A = 38.465
A = 38.47
So therefore the area of the circle is 38.47!

Answer:
90 inches squared
Step-by-step explanation:
To do this you would first find the area of the 2 triangles shown on the side so we would do 5 times 2 divided by 2 since that is how we solve this problem so we would get 5 inches squared for the 2 triangles then we would find the area of the square which is 100 since it is a 10 by 10 then you would subtract 5+5 by 100 which is 90 so 90 inches squared would be the answer
Answer:
Your correct answer is 90 sq. in.
Step-by-step explanation:
Find the area of the 2 triangles that are shown on the side.
5 x 2 divided by 2 = 5 sq. in.
Now, find the area of the square
The answer for this is 100 because it is a 10 x 10
Next, subtract
5 + 5 by 100 = 90
