Answer:
slope = -3
Step-by-step explanation:
Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]
Given points: (2, 0), (6, -12)
(2, 0) = (x1, y1)
(6, -12) = (x2, y2)
To find the slope, input the two given points into the formula used to find slope:
[tex]\frac{-12-0}{6-2}[/tex]
Simplify:
-12 - 0 = -12
6 - 2 = 4
[tex]\frac{-12}{4} = -\frac{3}{1}=-3[/tex]
The slope of the line is -3.
Hope this helps :)
Classify the polynomial as a monomial, binomial, trinomial, or none of these. x2 - 10x + 25
It is a trinomial because it follows the pattern of x^2 + bx + c. In this case, x^2 - 10x + 25. Also, it only has three numbers and two operation symbols, signifying a trinomial (three = tri).
A rectangular park is 135 yards long and 90 yards wide.
Give the length and width of another rectangular park that has the same perimeter but a smaller area.
Answer:
l = 140 yards , w = 85 yards
Step-by-step explanation:
1). l = 135 yards , w = 90 yards
P = 2 × 135 + 2 × 90 = 450 yards
A = 135 × 90 = 12,150 yards²
2). l = 140 yards , w = 85 yards
P = 2(140 + 85) = 450 yards
A = 140 × 85 = 11,900 yards²
Answer:
width= 100 yards
length= 125 yards

Solve the right triangle. Round decimal answers to the nearest tenth
Answer:
AB = 15
m∠A = 53.1°
m∠B = 36.9°
Step-by-step explanation:
From the picture attached,
By Applying Pythagoras theorem,
AB² = AC² + BC²
AB² = 9² + (12)²
AB² = 81 + 144
AB = √225
AB = 15
tan(B) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{12}{9}[/tex]
= 1.3333
B = [tex]\text{tan}^{-1}(1.3333)[/tex]
= 53.13
≈ 53.1°
Since, m∠A + m∠B + m∠C = 180°
m∠A + 53.1° + 90° = 180°
m∠A = 180°- 143.1°
= 36.9°
Answer:
AB = 15
m∠A = 53.1°
m∠B = 36.9°

There is a snowstorm in a certain town. In 1/2 hour, there was 7/8 inches of snow. It continues at the same rate for a total of 2 hours. Which statement is true about the amount of snow in the 2-hour period
Answer:
Since I don't know the statements, I'm gonna guess that if there is 7/8 snow in 1/2 hour then in 2 hours there is 3.5 inches of snow or 28/8 inches of snow in 2 hours.

A.) how much does it cost to buy 5 tickets?
B.) How many tickets can buy with $130?
Answer:
A) $77.50
B) 8 tickets
Step-by-step explanation:
A) c(x) = 17.5x - 10
Substitute 5 for x
c(x) = 17.5(5) - 10
Multiply
c(x) = 87.5 - 10
Subtract
c(x) = 77.5
B) 130 is the cost, so substitute 130 for c(x)
130 = 17.5x - 10
Add 10 to each side to move the constants to one side
140 = 17.5x
Divide each side by 17.5 to isolate the variable
8 = x

Step-by-step explanation:
1 meter equals 100 cmWe know that [tex]1meter=100centimeters[/tex] Now how many (100 cm)'s are in (300 cm)'s? There are 3 right?So if every 100 cm is also a meter and there are 3 of these (100cm)s then they are just the same as 3 meters[tex]100cm=1m\\300cm=(x)m[/tex] cross multiply[tex]100cm(x)m=300cm1m[/tex] divide both sides by 100cm[tex](x)m=3m[/tex]Answer:

Find the sum of the first 8 terms of the following series, to the nearest integer.
36, 30, 25, ...
Answer:
The sum of the first 8 terms will be:
[tex]\frac{1288991}{7776}[/tex]Step-by-step explanation:
Given the sequence
[tex]36, 30, 25, ...[/tex]
A geometric sequence has a constant ratio and is defined by
[tex]a_n=a_0\cdot r^{n-1}[/tex]
computing the common ratio
[tex]\frac{30}{36}=\frac{5}{6},\:\quad \frac{25}{30}=\frac{5}{6}[/tex]
[tex]r=\frac{5}{6}[/tex]
As the first element is
[tex]a_1=36[/tex]
so the nth term will be:
[tex]a_n=a_0\cdot r^{n-1}[/tex]
[tex]a_n=36\left(\frac{5}{6}\right)^{n-1}[/tex]
Geometric sequence sum formula
[tex]a_1\frac{1-r^n}{1-r}[/tex]
Plugin the values to determine the sum of the first 8 terms
[tex]n=8,\:\spacea_1=36,\:\spacer=\frac{5}{6}[/tex]
[tex]=36\cdot \frac{1-\left(\frac{5}{6}\right)^8}{1-\frac{5}{6}}[/tex]
[tex]=\frac{\left(1-\left(\frac{5}{6}\right)^8\right)\cdot \:36}{1-\frac{5}{6}}[/tex]
[tex]=\frac{36\left(-\left(\frac{5}{6}\right)^8+1\right)}{\frac{1}{6}}[/tex]
[tex]=\frac{36\left(-\frac{390625}{1679616}+1\right)}{\frac{1}{6}}[/tex]
[tex]=\frac{\left(1-\frac{390625}{1679616}\right)\cdot \:36\cdot \:6}{1}[/tex]
[tex]=\frac{216\left(-\frac{390625}{1679616}+1\right)}{1}[/tex]
[tex]=\frac{216\cdot \frac{1288991}{1679616}}{1}[/tex]
[tex]=216\cdot \frac{1288991}{1679616}[/tex]
[tex]=\frac{1288991\cdot \:216}{1679616}[/tex]
[tex]=\frac{278422056}{1679616}[/tex]
[tex]=\frac{1288991}{7776}[/tex]
Therefore, the sum of the first 8 terms will be:

Audrina goes to the mall with $50. She buys 3 shirts for $8.50 each, and 2 pairs of pants for $11 each. How much money does Audrina have left?
Answer:
2.5
Step-by-step explanation:
she has buys 3 shirts for 8.50 which = 25.5
then she buys 2 pair of pants for $22 because 2 x 11=22
so then 22 + 25.5 = 47.50
50.00- 47.50= 2.50

In △ACD, if AC ≅ AD, m∠A = (3x – 4)°, m∠C = (5x + 1)°, and m∠D = (7x – 27)°, find x and the measure of each angle. *
Answer:
x = 14
A = 38
B = 71
C = 71
Step-by-step explanation:
Since we have a triangle, the addition of the measure of all the measure of the angles give 180
Thus;
3x-4 + 5x + 1 + 7x-27 = 180
15x-30 = 180
15x = 180 + 30
15x = 210
x = 210/15
x = 14
To get the measure of each of the angles, we substitute for x
A = 3x-4 = 3(14) - 4 = 38
B = 5x + 1 = 5(14) + 1 = 70 + 1 = 71
C = 7x - 27 = 7(14) - 27 = 98-27 = 71

Step-by-step explanation:
At a department store, the price of a freezer is marked up 15% to $450.50.
What was the price of the freezer BEFORE the mark up?
Answer:
The price was $391.30.
Step-by-step explanation:
We can answer this using algebra:-
Let the original price be $x, then:
x + 15% of x = 450
x + 0.15x = 450
1.15x = 450
x = 450/1.15
x = 391.304
