Answer:
the slope would be -5
Step-by-step explanation:
in linear equations, the slope of the line is the coefficient of x
so in this case, it is -5

Given a square with two vertices of one side located at -5,-3 and -5,12 in square units what is its area
Answer:
225 units squaredStep-by-step explanation:
Lets find the distance (the side length of the square)
D=sqrt((x2-x1)^(2)+(y2-y1)^(2))
plug in the coordinates:
D=sqrt((-5-(-5))^(2)+(12-(-3))^(2))
D=sqrt(0^(2)+15^(2))
D=sqrt(15^(2))
D=15
Area of a square is side length squared
A=s^2
A=15^2
A=225 units squared

A cylindrical jar’s life has a radius of 4 inches. If the volume is 351.68in^3, approximately what is the height of the jar?
Answer:
7 inches
Step-by-step explanation:
The volume of a cylinder is calculated using
where r =4 inches is the radius and V=351.68 is the volume.
To find the height of the jar, we substitute these values and solve for h.
Divide both sides by 50.24 to get:
h=7 inches
Therefore the height of the jar is 7 inches

Answer:
The value of x is 66
Step-by-step explanation:
Answer:
66°
Step-by-step explanation:
The interior angles of a triangle always sum up to 180°. Looking at the first triangle, we see 48° + 66° + x = 180°, or x = 180° - (48° + 66°) = 66°. This is true because the triangles are congruent.

Answer:
the second integer is greater than the first
Step-by-step explanation:
Answer:
C. the second integer is greater than the first integer.
Step-by-step explanation:
this has to be true, because the farther you get to the right of the number line, the higher the numbers get.
It is not A or B, because we are not certain whether the second integer is negative or positive since we don't have any references.
And its not D, because the farther left you go, the less the numbers get.

4 tan 45° +(2 sin 45°) (6 cos 45°)
Answer:
value of 4 tan 45° +(2 sin 45°) (6 cos 45°) is 10.
Step-by-step explanation:
To solve this question we need to know value of
tan 45° = 1
sin 45° = [tex]1/\sqrt{2}[/tex]
cos 45° = [tex]1/\sqrt{2}[/tex]
we will be using above value sin the given expression as shown
[tex]4 tan 45 +(2 sin 45) (6 cos 45) = 4*1 + (2*1/\sqrt{2} )(6*1/\sqrt{2})\\ = 4 + (2/\sqrt{2}) (6/\sqrt{2})\\= 4 + (2*6)/(\sqrt{2}*\sqrt{2})\\= 4 + (12/2)\\= 4 + 6 = 10[/tex]
Thus, value of 4 tan 45° +(2 sin 45°) (6 cos 45°) is 10.

Which event is least likely to occur?
Answer:
C. picking a 4 of diamonds from a standard deck of cards
Step-by-step explanation:
First, we need to remember what the possible outcomes of a deck of cards, a flipped coin, and a standard number cube are.
A standard deck of cards has a total of 52 cards. There are 4 cards with a 7 on them. There is only one card with a 4 of diamonds. A nickel has 2 sides, and each side is equally likely show after a coin toss. A number cube has 6 faces with a different number from 1 to 6 on each face.
Now we find the probability of each situation. To find the probability of an event, divide the number of ways the desired event can happen by the total number of outcomes.
1. p(7) = 4/52 = 1/13 = 0.0769
2. p(tails) = 1/2 = 0.5
3. p(4 of diamonds) = 1/52 = 0.0192
4. p(number greater than 2) = 4/6 = 2/3 = 0.667
Answer: picking a 4 of diamonds from a standard deck of cards
state of the triangles in each pair are similar. If so, say how you know they are similar and complete the similarity statement. Part 5
Answer: d) similar, SAS similarity, ΔDGH

The total cost of a pair of shoes and a belt was $71.57. If the price of a pair of shoe was $1.79 less than the belt, what was the price of the pair of shoes?
Answer:
$34.89
Step-by-step explanation:
Here, we want to calculate the price of the pair of shoes.
Let the price of the belt be $x, we know that the price of pair of shoes would be x-1.79
so adding;
x + x-1.79 = 71.57
2x = 71.57 + 1.79
2x = 73.36
x = 73.36/2
x = $36.68
The price of pair of shoes = x-1.79 = 36.68-1.79 = $34.89
Find the area of a sector with a central angle of 180° and a diameter of 5.6 cm. Round to the nearest tenth.
Answer:
Step-by-step explanation:
Mathematically, the area of a sector can be calculated using the formula below;
area of sector = angle/360 * pi * r^2
From the question, angle = 180
pi= 22/7
r = d/2 = 5.6cm/2 = 2.8 cm
So the area of the sector is as follows;
A = 180/360 * 22/7 * 2.8^2
A = 2 * 22/7 * 2.8^2 = 49.28
which is 49.3 cm^2 to the nearest tenth
The perimeter of a rectangular yard which has one side that measures twenty-three metres equals 154 m. What are the dimensions of each side of the yard? PLEASE SHOW ME THE FORMULA YOU USE.
Answer: our rectangle is 23 meters of width and is 54 meters long.
Step-by-step explanation:
The perimeter of a rectangle is P = 2*W + 2*L
where W is the width and L is the length.
We know that W = 23m and P = 154m
then:
154m = 2*23m + 2*L
(154m - 2*23m)/2 = L = 54m
So our rectangle is 23 meters of width and is 54 meters long.

PLEASE HELP!!! GEOMETRY QUESTION
Answer:
Step-by-step explanation:
2y + 100 +6x-10=180(in a cyclic quadrilateral opposite angles are supplementary)
2y+6x+90 =180
2y + 6x = 90
dividing each side by 2
y+3x = 45 ........1
7x+1+2y+74 =180 ( same reason)
7x + 2y =105 ............2
multiplying 1 by 2
2y +6x =90........ 3
subtracting 3 from 2
7x+2y-2y-6x = 105-90
x = 15
substituting x=15 in 1
y+45 =45
y= 0

Madison has three jobs. This week she earned $124 waitressing, $30 delivering packages, and $46 babysitting. What percent of her money earned this week came from babysitting
Answer:
23%
Step-by-step explanation:
Answer:
23 %
Step-by-step explanation:

Percent earned babysitting
money earned babysitting / total * 100%
46/200 * 100 = 23 %
From the top of a fire tower, a forest ranger sees his partner on the ground at an angle of depression of 40º. If the tower is 45 feet in height, how far is the partner from the base of the tower, to the nearest tenth of a foot (Detailed explanation please)
Answer:
distance of his partner from the base of the tower ≈ 53.6 ft(nearest tenth)
Step-by-step explanation:
The forest ranger is on top of a fire tower and he sees his partner on the ground at the angle of depression of 40°. The tower is 45 ft tall.
The illustration forms a right angle triangle.
The adjacent side of the triangle is the distance from the partner to the base of the tower.
Using tangential ratio
tan 40° = opposite/adjacent
tan 40° = 45/adjacent
cross multiply
adjacent tan 40° = 45
divide both sides by tan 40°
adjacent =45/tan 40°
adjacent = 45/0.83909963117
adjacent = 53.6289116667
distance of his partner from the base of the tower ≈ 53.6 ft
