Question:
Where are the equations?
given the endpoint (-9,3) and (1,8) partition the segment into the ratio 2:3
Answer:
[tex]P = (-5,5)[/tex]
Step-by-step explanation:
Let the segments be A and B
[tex]A = (-9,3)[/tex]
[tex]B = (1,8)[/tex]
[tex]m:n = 2:3[/tex]
Required
Determine the endpoints after it is divided into ratios.
Let the point be represented with P
The formula to use is:
[tex]P = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})[/tex]
Where
[tex]A = (-9,3)[/tex] ----- [tex](x_1,y_1)[/tex]
[tex]B = (1,8)[/tex] ------ [tex](x_2,y_2)[/tex]
So:
[tex]P = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})[/tex]
[tex]P = (\frac{2 * 1 + 3 * -9}{2 + 3},\frac{2 * 8 + 3 * 3}{2 + 3})[/tex]
[tex]P = (\frac{-25}{5},\frac{25}{5})[/tex]
[tex]P = (-5,5)[/tex]

What is the sale price to the nearest cent? $239 television; 10% discount
Answer:
The sale price will be: $215.10
Step-by-step explanation:
We know that:
Sale price = Regular price × (100% - Discount %)
= Regular price × (100% - 10%)
= 239 × 90%
= 239 × 0.9
= 215. 10 $
Therefore, the sale price will be: $215. 10

Which statement about the hexagons must be true?
The hexagons are all the same size and shape.
The hexagons have corresponding sides that are proportional.
The hexagons have corresponding angles that are not congruent.
The hexagons are different shapes but the same size.
Answer: B- The hexagons have corresponding sides that are proportional.
The statement is true about hexagons, if Danielle created a painting using only similar hexagons, The hexagons have corresponding sides that are proportional, so option B is correct.
What is a hexagon?A hexagon is a two-dimensional geometric shape with six sides that may or may not have the same length. The hexagon shape can be seen in everyday objects like floor tiles, pencil cross-sections, clocks, honeycombs, etc.
Given:
Danielle created a painting using only similar hexagons,
A closed, two-dimensional shape with six equal sides and six equal angles is referred to as a regular hexagon. The regular hexagon has 120-degree angles on each side. And 120 x 6 = 720 degrees is the total of all inner angles.
Both have 6 vertices, 6 internal angles, and 6 sides, All six inner angles add up to 720 degrees, All six outer angles added together result in 360 degrees. These two hexagons are comparable because they have matching sides in the same ratio and matching angles that are both equal.
Thus, hexagon hexagons have corresponding sides that are proportional.

What is the decimal equivalent of 9 1/2%
The decimal equivalent of 9 1/2% is 0.095.
We have,
To explain the process of finding the decimal equivalent of 9 1/2%, we need to understand what a percentage represents and how to convert it to a decimal.
A percentage is a way of expressing a part of a whole in terms of hundredths. In this case, 9 1/2% represents 9.5 parts out of 100.
To convert a percentage to a decimal, we divide the percentage value by 100. This is because a percentage is essentially a fraction with a denominator of 100.
Now,
To find the decimal equivalent of 9 1/2%, we divide the percentage value by 100.
9 1/2% can be expressed as a fraction: 9 1/2% = 9.5/100.
Dividing 9.5 by 100 gives us the decimal equivalent:
= 9.5 ÷ 100
= 0.095
Therefore,
The decimal equivalent of 9 1/2% is 0.095.

At the local harvest festival Marty bought 2 pumpkin pie slices and 2 cups of hot chocolate $10.00. Patty bought 4 slices of pie and 5 cups of hot chocolate for $22.50. How much is a slice of pumpkin pie and how much is a cup of hot chocolate?
Answer:
1 cup of hot chocolate is $2.5
1 slice of pumpkin pie is $2.5
Step-by-step explanation:
Represent Pumpkin Pie with P and Hot Chocolate with C:
Marty:
[tex]2P + 2H = 10[/tex]
Patty:
[tex]4P + 5H = 22.5[/tex]
So, we have the following set of equation:
[tex]2P + 2H = 10[/tex] -------- (1)
[tex]4P + 5H = 22.5[/tex] -------- (2)
Multiply the first equation by 2
[tex]2(2P + 2H = 10)[/tex]
[tex]4P + 4H = 20[/tex] -------- (3)
Subtract (3) from (2)
[tex]4P + 5H = 22.5[/tex]
[tex]4P + 4H = 20[/tex]
--------------------------
[tex]5H - 4H = 22.5 - 20[/tex]
[tex]H = 2.5[/tex]
Substitute 2.5 for H in [tex]2P + 2H = 10[/tex]
[tex]2P + 2 * 2.5 = 10[/tex]
[tex]2P + 5 = 10[/tex]
[tex]2P = 10 - 5[/tex]
[tex]2P = 5[/tex]
Divide through by 2
[tex]P = \frac{5}{2}[/tex]
[tex]P=2.5[/tex]
Hence, 1 cup of hot chocolate is $2.5 and 1 slice of pumpkin pie is $2.5

Answer:
42 tickets
Step-by-step explanation:
If you divide all the choices by 8 they all equal an even number except 42
it is not possible for them to use forty-two tickets because forty-two is not a multiple of eight. since there are eight people, and each ride cost one ticket per person, they should use eight tickets for each ride. forty, twenty-four, and sixteen are all multiples of eight, and are therefore possible answers.

The height of mountain P is 1086 feet the height of Mt. Q is four times the height of Mt. P the area model shown below represents one way to find the height of Mt. Q what is the missing value for a, b and c
Answer:
ITS A I TOOK THE TEST
Step-by-step explanation:
Answer:
A=4000, B=80, C=24
Step-by-step explanation:
We have the fact that Mountain Q is 4 times the height of Mountain P. That's the "4" we have in the left side of our model. It's like having a multiplication table, next to the "4" we have "A" and upper this we have "1000", the only thing we have to do is Multiplify 4*1000=4000. The next letter we have is B and below it we have "320", we divided it by 4, 320/4=80. The last letter we have is C, and is below a "6", we only have to Multiplify it by 4, 6*4=24.
At the end we only sum our
A + 320 + c = 4344 (4 times the height of Mountain P).
1000 + B + 6 = 1086(the height of the Mountain P).
