Answer:
y = [tex]\frac{29}{3}[/tex]
Step-by-step explanation:
88 = 10y + 30 - 4y , that is
88 = 6y + 30 ( subtract 30 from both sides )
58 = 6y ( divide both sides by 6 )
[tex]\frac{58}{6}[/tex] = y , that is
y = [tex]\frac{29}{3}[/tex]
Marcia made spiral books to sell at her local craft fair. She forgot to count how many she made before the fair. She knows that she spent $176.80 in supplies to make the books. If each book requires two chipboard covers at a cost of $0.74 per cover and one spiral wire at a cost of $0.60, which equation can be used to find the number of books, n, she made?
A. 0.60n + 0.74n = 176.80
B. 0.60n + 1.48n = 176.80
C. 0.60n + 0.74 = 176.80
D. 0.60n + 1.48 = 176.80
Answer:
B) 0.60n+1.48n = 176.80
Step-by-step explanation:
0.60 for every spiral wire per book = 0.60*n
0.74 per chipboard cover, 2 needed for each book = 1.48 per book = 1.48*n
Put it together: 0.60n+1.48n = 176.80

Jill and Jack are exercising at a beach. They both start from the car park at one end of the beach. Jill runs at a constant speed and Jack walks at a constant speed. When Jill turns at the end of the beach to run back, she notices that Jack is then halfway along the beach. How far along the beach will Jack be when JIll next passes him
Jack is at (2/3) of the length of the beach (measuring from the point where they started).
How far along the beach will Jack be when JIll next passes him?Let's think that the whole beach is like a line track of length L.
We know that when Jill completes reaches the end (one complete run) Jack only completed half of it.
So in the time that jill covers the distance L, Jack covers a distance of L/2. So the ratio of their speeds is 2:1 (Jill's speed is double of Jack's speed).
At this point, Jill is on the end of the track and Jack is on the middle, so the distance between them is L/2.
Because of the ratios between the speeds, we know that when they meet again, Jill will have covered 2 thirds of that distance, and jack will cover the other third of that distance.
A third of that distance is:
(L/2)/3 = L/6
So, when they meet, Jack is at L/6 of the middle of the beach, which means that Jack is:
L/2 + L/6 = 3L/6 + L/6 = 4L/6 = 2L/3
Jack is at (2/3) of the length of the beach (measuring from the point where they started).

Mark has 580 stamps. Debbie has 720 stamps than Mark. How many stamps must Debbie give to mark so that Mark have 120 more than she?
480 stamps must be given to Mark
Answer: 130 stamps.
Step-by-step explanation:
Let amount оf the stamps Debbie must give to Mark so that Mark have 120 more than she is x.
Hence,
(580+x)-(720-x)=120
580+x-720+x=120
2x-140=120
2x=260
2*x=2*130
x=130.
So, 130 stamps Debbie must give to Mark so that Mark have 120 more than she.

What is the area formula of the parallelogram:
⇒ Area = Base * Height
Let's gather the information necessary:
Base: 12 inHeight: 11 inLet's solve:
⇒ Area = 12 * 11 = 132 in²
Answer: 132 in²

#LearnwithBrainly
Answer:
132 inches squared
Step-by-step explanation:
Area is 132 inches squared
Method 1:
Area of parallelogram = base x height = 11inches x 12 inches = 132 inches squared
Method 2:
Move the triangle divided by the dotted line on the right to the left.
It becomes a rectangle of 11 inches by 12 inches. 11 inches x 12 inches = 132 inches squared.

The x-intercepts of the given quadratic function are -2 and 9.
What is a quadratic function?
A quadratic function is a function represented as, f(x) = ax2 + bx + c, with a, b, and c being integers and a not equal to zero. A parabolic curve represents the graph of a quadratic function.
A polynomial's highest degree reveals how many roots the polynomial has. The values for which the polynomial's numerical value is equal to zero are known as a polynomial's roots (also known as zeros of a polynomial). On a graph, the points where the polynomial's graph and the x-axis cross are the roots (x-intercepts).
Roots of the Quadratic Equation
Due to its degree of 2, a quadratic function can only have a maximum of two real roots. In order to find the roots of a quadratic equation, we equate its factors to 0. Thus, in this case, we have,
(x+2)*(x-9)=0
∴ x+2=0
⇒ x=-2
Similarly,
x-9=0
⇒ x=9
Hence, the x- intercepts of the given quadratic function come out to be -2 and 9.

Add both together to eliminate x
2y = 0
y = 0
Substitute y = 0 into y = 2/3x + 1 to find x
0 = 2/3x + 1

What is percentage?Percentage, which is a relative figure used to denote hundredths of any quantity. One percent (symbolized as 1%) is equal to 100 parts; hence, 100 percent denotes the complete amount, and 200 percent designates double the amount specified.
A typical method for calculating a percentage is the formula shown below:
Determine the total amount of what you want to find a percentage. Divide the number to determine the percentage. Multiply the value by 100.Calculation for the weight of Cooper as an adult;
Cooper's present weight is 20 pounds.
He will weigh about 350% as much as his current weight.
Calculate 350% of 20 pounds.
= (350×20)/100
= 70
The increment of the weight of Cooper will be 70 pounds.
Thus, the total weight is 20 + 70 = 90.
Therefore, the weight of Cooper after 350% as an adult would be 90 pounds.

Answer:
x = 90
Step-by-step explanation:
In this figure the exterior angle is 130°
An exterior angle is the sum of the interior angles. The interior angles are x and 40 so x + 40 = 130 giving x = 130-40 = 90
Answer:
∠ x = 90°
(90 degrees)
Step-by-step explanation:
When two angles combine to make a straight line, we know that their angle values must add up to 180
Here, we can see that 130 combines with an inner angle to form a straight line. (I will be calling this interior angle z )
So, 130 + z = 180
130 + z = 180
- 130 -130
z = 50
We also know that all angles in a triangle must add up to 180 degrees, and because we know the two other angles of our triangle now, we can find x
z + x + 40 = 180
50 + x + 40 = 180
90 + x = 180
- 90 -90
x = 90
So, the measure of angle x is 90°
