Answers
Given:
The endpoints are
6) (-7, -10), (-2, -3)
7) (-4,-3), (8, 2)
Required:
We need to find the midpoint of the given endpoints.
Explanation:
Consider the midpoint formula.
\(M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\)6)
Consider the points (-7, -10), and (-2, -3).
\(Substitutte\text{ }x_1=-7,x_2=-2,y_1=-10,\text{ and }y_2=-3\text{ in the formula.}\)\(M=(\frac{-7+(-2)}{2},\frac{-10+(-3)}{2})\)\(M=(\frac{-7-2}{2},\frac{-10-3}{2})\)\(M=(\frac{-9}{2},\frac{-13}{2})\)\(M=(-4.5,-6.5)\)7)
Consider the points (-4,-3), and (8, 2).
\(Substitutte\text{ }x_1=-4,x_2=8,y_1=-3,\text{ and }y_2=2\text{ in the formula.}\)\(M=(\frac{-4+8}{2},\frac{-3+2}{2})\)\(M=(\frac{-4+8}{2},\frac{-3+2}{2})\)

Solve ΔABC using the Law of Sines
1. A = 29°, C = 63°, c = 24
2. A = 72°, B= 35°, c = 21
Answers
Answer:
1) B = 88°, a = 13.1, b = 26.9
2) C = 73°, a = 20.9, b = 12.6
Step-by-step explanation:
To solve for the remaining sides and angles of the triangle, given two sides and an adjacent angle, use the Law of Sines formula:
\(\boxed{\begin{minipage}{7.6 cm}\underline{Law of Sines} \\\\$\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}$\\\\\\where:\\ \phantom{ww}$\bullet$ $A, B$ and $C$ are the angles. \\ \phantom{ww}$\bullet$ $a, b$ and $c$ are the sides opposite the angles.\\\end{minipage}}\)
Question 1Given values:
A = 29°C = 63°c = 24As the interior angles of a triangle sum to 180°:
\(\implies A+B+C=180^{\circ}\)
\(\implies B=180^{\circ}-A-C\)
\(\implies B=180^{\circ}-29^{\circ}-63^{\circ}\)
\(\implies B=88^{\circ}\)
Substitute the values of A, B, C and c into the Law of Sines formula and solve for sides a and b:
\(\implies \dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}\)
\(\implies \dfrac{a}{\sin 29^{\circ}}=\dfrac{b}{\sin 88^{\circ}}=\dfrac{24}{\sin 63^{\circ}}\)
Solve for a:
\(\implies \dfrac{a}{\sin 29^{\circ}}=\dfrac{24}{\sin 63^{\circ}}\)
\(\implies a=\dfrac{24\sin 29^{\circ}}{\sin 63^{\circ}}\)
\(\implies a=13.0876493...\)
\(\implies a=13.1\)
Solve for b:
\(\implies \dfrac{b}{\sin 88^{\circ}}=\dfrac{24}{\sin 63^{\circ}}\)
\(\implies b=\dfrac{24\sin 88^{\circ}}{\sin 63^{\circ}}\)
\(\implies b=26.9194211...\)
\(\implies b=26.9\)
\(\hrulefill\)
Question 2Given values:
A = 72°B = 35°c = 21As the interior angles of a triangle sum to 180°:
\(\implies A+B+C=180^{\circ}\)
\(\implies C=180^{\circ}-A-B\)
\(\implies C=180^{\circ}-72^{\circ}-35^{\circ}\)
\(\implies C=73^{\circ}\)
Substitute the values of A, B, C and c into the Law of Sines formula and solve for sides a and b:
\(\implies \dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}\)
\(\implies \dfrac{a}{\sin 72^{\circ}}=\dfrac{b}{\sin 35^{\circ}}=\dfrac{21}{\sin 73^{\circ}}\)
Solve for a:
\(\implies \dfrac{a}{\sin 72^{\circ}}=\dfrac{21}{\sin 73^{\circ}}\)
\(\implies a=\dfrac{21\sin 72^{\circ}}{\sin 73^{\circ}}\)
\(\implies a=20.8847511...\)
\(\implies a=20.9\)
Solve for b:
\(\implies \dfrac{b}{\sin 35^{\circ}}=\dfrac{21}{\sin 73^{\circ}}\)
\(\implies b=\dfrac{21\sin 35^{\circ}}{\sin 73^{\circ}}\)
\(\implies b=12.5954671...\)
\(\implies b=12.6\)

Answers
Answer:

Step-by-step explanation:
Circumference = π X D (D = diameter = 2 X radius).
Diameter = 32.
Circumference = π (32) = 32π.
Divided into 8 slices = 1/8 of the circumference = 32π/8 = 4π.

URENT PLS HELP ME
Answers
For the given composite figure the total area of the figure is 198 m².
What is area of rectangle?
To find the area of a rectangle, you need to multiply its length by its width. The formula for the area of a rectangle is:
Area = Length x Width
To find the area of the six-sided composite figure, lets divide it into two smaller shapes: a rectangle and a triangle.
The rectangle has a length of 10 meters and a width of 18 meters, so its area is:
10 meters × 18 meters = 180 square meters
The triangle has a base of 18 meters and a height of 2 meters, so its area is:
(1/2) × 18 meters × 2 meters = 18 square meters
The total area of the six-sided composite figure is the sum of the areas of the rectangle and the triangle:
180 square meters + 18 square meters = 198 square meters
Therefore, the total area of the figure is 198 m².

Cost price of shirt after giving discounts is equals to \(\$68\).
What is Cost price?" Cost price is defined as the price to be paid at the time of purchase any product."
According to the question,
Initial cost price of shirt \(= \$100\)
First discount \(= 15\%\)
Discount amount \(= 15\%\) of \(100\)
\(= \frac{15}{100} \times 100\\\\= \$15\)
Cost price after first discount \(= 100 - 15\)
\(= \$85\)
Second discount \(= 20\%\)
Discount amount \(= 20\%\) of \(85\)
\(= \frac{20}{100} \times 85\\\\= \$17\)
Cost price after first discount \(= 85 - 17\)
\(= \$68\)
Hence, cost price of shirt after giving discounts is equals to \(\$68\).

The rectangle will have a 548.1 square foot size and a 94.2-foot periphery.
What are the rectangle's area and perimeter?Let W be the rectangle's width and L its length.
The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be
Perimeter of the rectangle = 2(L + W) units
The area of the rectangle is the multiplication of the two different sides of the rectangle. Then the rectangle's area will be
Area of the rectangle = L×W square units
The length is 21 feet and the width is 26.1 feet.
The perimeter of the rectangle will be
P = 2 (21 + 26.1)
P = 2 x 47.1
P = 94.2 feet
The area of the rectangle will be
A = 21 x 26.1
A = 548.1 square feet
The rectangle will have a 548.1 square foot size and a 94.2-foot periphery.

Alice and Bob each have a certain amount of money. If Alice receives n dollars from Bob, then she will have 7 times as much money as Bob. If, on the other hand, she gives n dollars to Bob, then she will have 2 times as much money as Bob. If neither gives the other any money, what is the ratio of the amount of money Alice has to the amount Bob has?
Answers
The ratio of the amount of money Alice has to the amount Bob has is approximately 3.36 : 1.
How to find the ratio of money ?According to the problem, two equations can be set up:
If Alice receives n dollars from Bob, then she will have 7 times as much money as Bob. This gives us the equation:
A + n = 7(B - n)
If Alice gives n dollars to Bob, then she will have 2 times as much money as Bob. This gives us the second equation:
A - n = 2(B + n)
We can rearrange these equations to make them easier to solve:
8n = 7B - A
3n = A - 2B
Setting these equal to each other, since they are both equal to 24n, gives:
21B - 3A = 8A - 16B
37B = 11A
A / B = 37 / 11
= 3. 36

Answers
Answer:
The family has 1/4 of the strawberries left to snack on, or 31 left to snack on.
Step-by-step explanation:
Since they gave away 1/4 of the strawberries to their neighbor, and the others were used in a pie, that means that 1/4 of the strawberries remain. You do 124/4 in which 1/4 of that is 31, since 31x4 is equal to 124.
which is better to buy 5 pack for 9.98 or 7 pack for 14.14
Answers
A person wants to buy 5 pack of something for $9.98 or 7 packs of something for $ 14.14
The problem is asking is what is the better buy (the one that costs less)
So we compare the cost per unit:
with the 5 pack we get $9.98 / 5 = $ 1.996 per unit which we round to $2.00
with the 7 pack we get $14.14 / 7 = $2.02 per unit
So, the better option is the first one (the 5 pack per $9.98) which saves us 2 cents per units.

The financial model contains 10 microcircuits, and the scientific model contains 20. A contract with a supplier of semiconductor chips requires the use of at least 3200 chips each day. A contract with a supplier of the off-on switches used in both calculators requires the use of at least 300 switches each day. The company would like to produce at least 100 financial models each day.
