Step-by-step explanation:
The work involved in making the poster is the product of students and hours:
work = students × hours = (9 students)(10 hours) = 90 student·hours
__
neededIf hours are reduced to 6, the necessary number of students is ...
90 student·hours = (6 hours)(students)
(90 student·hours)/(6 hours) = 15 students . . . . . . divide by 6 hours
additionalIf 15 are needed, then the number that must be added is ...
15 -9 = 6 . . . . students need to be added

HELP!! The measure of two supplementary angles are in the ratio 4:2. Find the two angles.
Hey there!
Supplementary angles always equal 180° when combined. We have our ratio which is 4:2. When we combine them, we have six. This is on a different scale than 180, so we need to divide 180 by six to see how much bigger we need to make our ratio so we can find the angles.
180/6=30
As we can see, our parts of the ratio are 1/30 the size of our actual angle. To find our angles now, we multiply each number by 30.
4(30):2(30)=120:60
As you can see, if we add 120 and 60, it equals 80, and if you simplify the ratio it is still 4:2.
Your angles are 120° and 60°.
I hope this helps!
The measure of the two angles is 120 and 60 degrees if the angles are in the ratio of 4:2.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called a "Angle."
It is given that:
The measure of two supplementary angles are in the ratio 4:2.
From the question:
4x + 2x = 180
6x = 180/6
x = 30
The first angle = 4x = 4(30) = 120 degrees
The second angle = 2(30) = 60 degrees
Thus, the measure of the two angles is 120 and 60 degrees if the angles are in the ratio of 4:2.

Without drawing the graph of the function y=1.2x−7, see if the graph passes through points: (100; 113)
Answer:
(100,113) is on the graph of y = 1.2x -7
Step-by-step explanation:
y=1.2x−7
Substitute the point in and see if the equation is true
113 = 1.2 (100) -7
113 =120 - 7
113 = 113
This is true, so the point is on the graph

Please help me and then solve for angle 2 please I really need help
Answer:
Angle 1 is 45
Angle 2 is 90
Step-by-step explanation:
ABCD is a square, so by definition, all of its angles equal 90:
∠ABC = ∠BCD = ∠CDA = ∠DAB = 90
We also see that AC and BD are diagonals of the square, and by definition, these diagonals bisect those angles. In other words, these diagonals cut those angles in half.
∠DAB = ∠DAE + ∠BAE
That means ∠DAE = ∠BAE = 90/2 = 45 degrees, which also means angle 1 is 45 degrees.
Also by definition, when the diagonals intersect, they form a right angle. In other words, angle 2 will be 90 degrees.
Thus, the answer is angle 1 is 45 and angle 2 is 90.
Answer:
1: 45°
2: 90°
Step-by-step explanation:
Diagonals of a square are Perpendicular bisectors of each other, hence AEB is an isosceles right angle triangle
Angle at E = 90
Angle at A = (180-90)/2 = 45

The solution of equation is (5/2, 7/2)
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
-4x + 5y = 8
6x - y = 11
Now, using the graphical method the lines of the equation intersect at
x = 2.5 and y = 3.5.

Ms. Nina wants to buy candy mix for $1.00 per pound. If she already bought 50 pounds of candy for $1.20 per pound, how many pounds that costs 80 cents per pound must she buy?
Answer:
She must buy 50 pounds of the other candy in order to have a mix that costs $1 per pound.
Step-by-step explanation:
Her goal is to have a candy mix that has a cost of $ 1.00 per pound, therefore the relation [tex]\frac{\text{total cost}}{\text{total weigh}}[/tex] must be equal to 1. She already bought a total of 50 pounds of a $1.2 per pound candy, therefore she spent:
[tex]\text{spent first candy} = 50*1.2 = 60[/tex]
She wants to buy "x" of a 80 cents per pound candy, therefore if we sum it's weigh "x" with 50 pounds, then it must be equal to it's value summed with 60. We have:
[tex]50 + x = 60 + 0.8*x\\x - 0.8*x = 60 - 50\\0.2*x = 10\\x = \frac{10}{0.2} = 50\\[/tex]
She must buy 50 pounds of the other candy in order to have a mix that costs $1 per pound.

Which is the correct calculation for the volume of the prism?
A prism has a length of 8 millimeters, height of 2 and one-half millimeters, and width of 8 and one-half millimeters.
2 and one-half + 8 + 8 and one-half = 19 mm3
2 and one-half times 8 + 8 and one-half = 28.5 mm3
8 times 8 and one-half = 68 mm3
2 and one-half times 8 times 8 and one-half = 170 mm3
Answer:
its D
Step-by-step explanation:
The correct calculation for the volume of the prism is 2 and one-half times 8 times 8 and one-half = 170 mm3
What is a volume?Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like length, width and height of cube or cubes.
The volume will be calculated as:-
V = L x W x H
V = [tex]2\dfrac{1}2}[/tex] x 8 x [tex]8\dfrac{1}{2}[/tex]
V = ( 5/2) x 8 x ( 17/2 )
V = 170 mm³
