Harley and Natalie are each given 2 1/3 kg of clay Harley makes as many balls of clay as he can from his clay. Each ball weighs 1/6 kg. Natalie makes ten more clay balls than Harley (each weighing the same).
If Natalie used up all her clay, how much does each of her clay balls weigh?
Solution:
Note that:
One ball made by Harley = 1/6 kgEach student was given 2 1/3 kg of clayNatalie made 10 more balls (same weight) than Harley.Solving for how much balls made by Harley.
7/3 ÷ 1/6=> 7/3 x 6=> 7 x 2=> 14 balls.Solving for how much balls made by Natalie.
14 + 10 => 24 ballsFinding out the weight of each ball made by Natalie.
7/3 ÷ x = 24=> 7/3 × 1/x = 24=> 7/3x = 24=> 7 = 72x=> x = 7/72 kgNatalie's balls weigh about 7/72 kg.

(20 points, please help!) Using the diagram, what are the measures of angles 1, 2 and 3?
Answer:
angle 1 = 50°
angle 2 = 70°
angle 3 = 50°
Step-by-step explanation:
We know the top triangle equals 180 degrees.
angle 1 + 60 + 70 = 180
angle 1 + 130 = 180
angle 1 = 50
Because of parallel lines, we know that opposite angles will be equal.
What I mean by this is that angle 1 = angle 3 and angle 2 = 70 degrees.
angle 1 = 50°
angle 2 = 70°
angle 3 = 50°

Mia went shopping for a new pair of pants because of a sale. The price on the tag was $34, but Mia paid $27.20 before tax. Find the percent discount.
Answer:
20%
Step-by-step explanation:
$34 - $27.20 = $6.80
[tex]\frac{6.80}{34} = 0.2[/tex]
0.2 x 100 = 20%
:]
The percent of discount in the tag is, 20%.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
The price on the tag was $34, but Mia paid $27.20 before tax.
Here, The discount price = $34 - $27.20
= $6.8
Hence, The percent discount = 6.8 / 34 × 100
= 20%

Wynona buys some new boots that are priced $85. 79. She gets successive discounts of 10% followed by 5% off on the boots. The purchase price of Wynona’s boots is _____ of the original price. A. 84% b. 84. 5% c. 85% d. 85. 5%.
The purchase price of Wynona’s boots is 85.5% of the original price.
It is given that
The marked price of boots = $85.79
What is the percentage?The percentage is a relative value indicating the hundredth parts of any quantity.
Price after a discount of 10% = [tex]85.79 - 85.79*10/100 = 77.211[/tex]
Price after another discount of 5% = [tex]77.211-77.211*5/100 = 73.35[/tex]
[tex]\frac{PurchasePrice}{OriginalPrice}*100 =\frac{73.35}{85.79}*100 = 85.5[/tex]
Therefore, The purchase price of Wynona’s boots is 85.5% of the original price.

Step-by-step explanation:
for a function every valid x value must have exactly 1 y value. several x values can have the same y value assigned but never can a x value have multiple y values assigned.
the valid x values for m are -3. -2, -1, 1, 2, 3.
and indeed, every one of these values has exactly one y value out of the possible 1, 4, 9 values.
so, m is a function.
but the inverse function turns the meaning of x and y upside-down. x becomes y and y becomes x.
and now we see that for the inverse the x value of 1 has two assigned y values (-1, 1).
the same for 4 (-2, 2) and 9 (-3, 3).
so, the inverse is NOT a function.

-10x-2y=16 What is the slope intercept form of that?
Answer:
The slope is 5 and the slope or y intercept is 8 and the equation is y = -5x + 8.
Step-by-step explanation:
Turn it into -2y = 10x + 16
Then divide by -2
y=-5x+8
The slope is 5 and the slope or y intercept is 8 and the equation is y = -5x + 8.
Answer: y = 5x + 8
Step-by-step explanation:
-10x - 2y = 16 —> add 10x to each side
2y = 16 - (-10x) —> add the opposite & flip the numbers so the variable is closest to the equal sign
2y = 10x + 16 —> divide 2 by each side
y = 10x/2 + 16/2 —> simplify
y = 5x + 8

In the figure shown, L is the center of the circle and PQ is a chord of the circle measuring 20 cm.
What is the length, in cm, of PL? Round to the nearest hundredth digit.
Show me:
(a) length of segment PM (1 point)
(b) what circle property did you use to find the length of PM (1 point)
(c) what formula/theorem did you use to calculate the length of segment PL (1 point)
(d) all math used to calculate the length of segment PL (1 point)
Round your answer to the nearest hundredth digit.
Hence, section PL measures about 18.03 cm in length (rounded to the nearest hundredth digit).
what is length ?The length of a one-dimensional object, such as a line, curve, or straight segment, is measured by the fundamental physical quantity known as length. It is a way to gauge the separation between two points or the size of an object along a specific axis. The International System of Units (SI) uses metres as the unit of length (m). One of the most important ideas in geometry is length, which is used to describe the characteristics of geometric forms and shapes. For instance, the length of a circle is the distance around its circumference, whereas the length of a line segment is the distance between its endpoints.
given
(A) We must first determine the length of chord PQ in order to determine the length of segment PM. Since LM is the perpendicular bisector of PQ in the figure, PM is equal to MQ. PQ's length is 20 cm, so PM and MQ's lengths are each 50 percent of that, or:
PM=MQ=20/2=10 cm
Sqrt(PM2 + LM2) = PL
(d) When we enter the values from parts (a) and (c), we obtain:
Sqrt(10 + 15) = PL
Sqrt(100 + 225) = PL
Sqrt = PL (325)
PL ≈ 18.03 cm
Hence, section PL measures about 18.03 cm in length (rounded to the nearest hundredth digit).
