Answer:
88%
Step-by-step explanation:
There are 67 questions on an exam
You miss 8 questions
The first step is to calculate the number of correct questions
= 67-8
= 59
Therefore the grade can be calculated as follows
= 59/67 × 100
= 0.880 × 100
= 88%
Hence the grade is 88%

which of the following sets of numbers could represent the three sides of a triangle
A 6,20,28
b 4,11,15
c 9,19,30
d 5,15,19
Answer:
d 5,15,19
Step-by-step explanation:
The sum of the shortest two sides must be longer than the longest side. That is only the case for selection D.
__
If the sum is equal to the longest side, the segment ends will meet, but the "triangle" will look like a line segment. Many authors do not allow such a thing to be called a triangle. Hence, 'b' is not an answer to this question.
(Some authors do allow such a triangle, in which case, there would be two answers here: B and D.)
Consider the point. (1, 4, 5) What is the projection of the point on the xy-plane?
Given :
A point ( 1 ,4 ,5 ).
To Find :
The projection of the point on the xy-plane .
Solution :
Now , to find projection of a point in a plane in a plane we need to replace the coordinate of that remaining axis which is not in the plane .
Here , the plane given is xy-plane . So , remaining axis is z .
So , we replace coordinate of z =0 .
Therefore , the projection of the point ( 1 ,4 ,5 ) on the xy-plane is ( 1 ,4 ,0 ) .
Hence , this is the required solution .

Solve for y in terms of x. 16x + 4/3 y = 21
Answer:
y= -12x+63/4
Step-by-step explanation:
16x + 4/3 y = 21
4/3 y =21-16x
4y=3(21-16x)
4y=63-48x
y=63/4-48/4 x
y=-12x+63/4

The question is an illustration of linear equation, and the solution to the linear equation is x = -5
How to determine the solution?The equation is given as:
[tex]\frac 23x - \frac 12 = \frac 13 + \frac 56x[/tex]
Multiply through by 6
4x - 3 = 2 + 5x
Collect like terms
4x - 5x = 2 + 3
Evaluate the like terms
-x = 5
Divide both sides by -1
x = -5
Hence, the solution to the linear equation is x = -5

Answer:
width=3
Step-by-step explanation:
area=length X width
length=4 X width
=>area=4 X width X width
=>area=(2 X width)^2
=>36=(2 X width)^2
=>6=2 X width
=>width=3
the area of a rectangle is length times width
A = L times W
A = 26. so 36 = L times W
The length is 4 times the width
L = 4W
Thus, we can switch L to 4W in the area equation
36 = 4W ×W = 4W²
36 ÷ 4

3y^2+y^- 5+ 4y+2y^3+8
Answer:
9y+3
Step-by-step explanation:
you add all the common numbers and you end up with:
9y^6+3+y^-5
then you put the y^-5 under the other numbers and make it positive so it becomes:
9y^6+3/y^5, then you subtract the exponents of y: 6-5, so that cancels out the y on the bottom making it:
9y+3
3. At the start of summer, Ben has $250 . He takes a summer
job and saves $ 150 per week. Tim has $ 1,650 at the start of
summer , he travels and spends $ 200 per week. At the end of
which week do Ben and Tim have the same amount of money ?
Answer:
Week 4
Step-by-step explanation:
Ben has $250 in the beginning. He saves $150 per week.
y = 150x + 250
Tim has $1,650 in the beginning. He spends $200 per week.
y = 1650 - 200x
We are trying to find which x-value produces the same y-value for both equations. You can do this by setting both equations equal to each other.
150x + 250 = 1650 - 200x
(150x + 250) + 200x = (1650 - 200x) + 200x
350x + 250 = 1650
(350x + 250) - 250 = (1650) - 250
350x = 1400
(350x)/350 = (1400)/350
x = 4
By week 4, they will have the same amount of money.

The volume of a volleyball is about 288 cubic inches. what is the radius of the volleyball, to the nearest tenth of an inch? use 3.14 for π.
[tex]r = \sqrt{ \frac{3v}{4\pi} } [/tex]
Answer:
The radius of the volleyball is 8.3 inches
Step-by-step explanation:
Given
[tex]r = \sqrt{\frac{3v}{4\pi}}[/tex]
[tex]v = 288[/tex]
Required
Determine the value of r
To do this, we simply substitute 288 for v and 3.14 for π in the given equation.
This gives
[tex]r = \sqrt{\frac{3v}{4\pi}}[/tex]
[tex]r = \sqrt{\frac{3 * 288}{4 * 3.14}}[/tex]
[tex]r = \sqrt{\frac{864}{12.56}}[/tex]
[tex]r = \sqrt{68.7898089172}[/tex]
[tex]r = 8.29396219651[/tex]
[tex]r = 8.3\ inch[/tex] (Approximated)

The radius of the volleyball is 8.3 inches

Which equation can be used to solve for x in the following diagram? Choose 1 answer:
Answer:
D) 60=(x+45)
Step-by-step explanation:
D. Since the two are equal, you need to put the two on opposite sides of the equation. The equation doesn’t involve 90 or 180 degrees, so no reason to have them.
Solving for x this way, you’d get 15, which is correct.
Look at the arrows in the following drawings
Answer:
a) perpendicular b) parallel c) perpendicular d) neither
Step-by-step explanation:
Perpendicular means that the lines will intersect/cross and create a 90 degree angle
Parallel lines will never intersect/cross because they are going the same way.
