Olivia's family drove to Disneyland for spring break. Her mom and dad shared driving duties for a total of 14 hours. Her mom drove 65 miles per hour and her dad drove 60 miles per hour. They drove a total of 895 miles. How many hours did each person drive.
Answer: Dad = 3 hours
Mom = 11 hours
Step-by-step explanation:
Let the number of hours driven by her mum be m.
Let the number of hours driven by her dad be d.
We can form equation from the question as:
d + m = 14 ........... i
60d + 65m = 895.......... ii
Since d + m = 14, d = 14 - m
Substitute 14 - m into d in equation ii
60d + 65m = 895
60(14 - m) + 65m = 895
840 - 60m + 65m = 895
840 + 5m = 895
5m = 895 - 840
5m = 55
m = 11
The mother drove for 11 hours
Since d + m = 14
d + 11 = 14
d = 14 - 11
d = 3
The father drive for 3 hours

PARTITION A DIRECTED LINE SEGMENT
1. Given G(-5,5) and H(4, -7), find the coordinates of p so that p partitions GH in the ratio 1:2.
Point P?
Answer:
The coordinates of point P are (-2, 1)
Step-by-step explanation:
The coordinates of the partition point (x, y) of a line segment whose endpoints are (x1, y1) and (x2, y2) at ratio m: n are
x = [tex]\frac{mx2+nx1}{m+n}[/tex]y = [tex]\frac{my2+ny1}{m+n}[/tex]∵ P partitions segment GH in a ratio 1: 2
∴ P = (x, y)
∴ m = 1 and n = 2
∵ G = (-5, 5) and H = (4, -7)
∴ x1 = -5 and x2 = 4
∴ y1 = 5 and y2 = -7
→ Substitute them in the rule above to find x and y
∵ x = [tex]\frac{1(4)+2(-5)}{1+2}[/tex] = [tex]\frac{4-10}{3}[/tex] = [tex]\frac{-6}{3}[/tex]
∴ x = -2
∵ y = [tex]\frac{1(-7)+2(5)}{1+2}[/tex] = [tex]\frac{-7+10}{3}[/tex] = [tex]\frac{3}{3}[/tex]
∴ y = 1
∴ The coordinates of point P are (-2, 1)
Suppose Metro by T-Mobile wants to offer a simple extended warranty plan. If your phone is damaged, they will repair it for up to $50. If you lose or destroy your phone, they will give you a $200 voucher towards a new phone. The company believes that 5% of customers will need the replacement voucher and 10% will request a repair. What is the standard deviation?
Answer:
45
Step-by-step explanation:
Given that :
Voucher awarded (x) :
Repair = $50
Lose or destroy = $200
P(x):
Replacement voucher = 5%
Repair voucher = 10%
X ______ 50 ______ 200
P(x) ____ 0.1 _______ 0.05
Expected variance Var(X) :
ΣX²p(x) - E(x) ;
E(x) = Σx*p(x) = (50*0.1) + (200*0.05) = 15
ΣX²p(x) = Σ[(50^2 * 0. 1) + (200^2 * 0.05)] = 250 + 2000 = 2250
Var(X) = 2250 - 15^2 = 2025
Standard deviation = √Var(x)
Standard deviation = √2025
Standard deviation = $45

Cameron is making a rectangular picture frame. The height of the frame is 6 inches
longer than its width. The perimeter of the frame is 76 inches. Which of these
systems of equations below best describes the dimensions of the picture frame?
Whats on the photo are the answer choices
A: h+w=6
h+w=76
B: h-w=6
2h+2w=76
C: h+w=6
2h+2w=76
D: h-w=6
h•w=6
Answer:
Its the second answer choice, hopefully I'm not to late
Step-by-step explanation:
The perimeter of the rectangle is given as,
P = 2 (h + w)
The dimensions of the picture frame can be best described by
h - w = 6
2h + 2w = 76
Option B is the correct answer.
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
A rectangular picture frame.
Width of the rectangle = w
The height of the frame is 6 inches longer than its width.
This can be written as,
h = w + 6 _____(1)
The perimeter of the frame is 76 inches.
The perimeter of the rectangle is given as,
P = 2 (h + w)
Now,
76 = 2 (h + w)
76 = 2h + 2w ______(2)
From (1) and (2) we get,
h - w = 6
2h + 2w = 76
Thus,
The dimensions of the picture frame can be best described by
h - w = 6
2h + 2w = 76
Option B is the correct answer.

Sarah walked 1 mile yesterday. Today she will walk at a rate of 3 miles per hour. Which graph shows her two-day total walking distance, d, based on the number of hours, h, that she spends walking today?
Answer:
Graph C
Step-by-step explanation:
If a graph represents the linear equation,
d = mh + b
Here 'm' = slope of the line
b = y-intercept
d = Distance traveled
h = duration or time
For the given question,
Slope of a line represents the rate of change in distance or speed and y-intercept represents the initial distance traveled or the distance traveled on 1st day.
So the equation will be,
d = 3h + 1
Input-output values for the graph,
h 0 1 2 3 4
d 1 4 7 10 13
We find all these points lying on a straight line give in Graph C.

how to write slope intercept equation y=mx+b?
plz help
Answer:
the form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a. The form y=m(x-a) is essentially different from the other two forms, and means slope m and x-intercept (instead of y-intercept) a.

2. Solve (x – 4)(x + 7). (2 points) O x = 4, X= 7 X = =4, x = -7 x = 4, X = -7 X = -4, X = 7
Answer:
X = 4, x = -7
Step-by-step explanation:
You can set each equation in the parenthesis Equal to 0.
x - 4 = 0 and x + 7 = 0
start with x - 4 =0
add 4 to both sides
x = 4.
then do x +7 =0. subtract 7 from both sides.
x = -7
so x =4, and x = -7

Amin is attempting to solve the following equation. (x+1)(x+4)=(x-2)(x-3) solve the equation
Answer: x = 1/5
After expanding, (x+1)(x+4) = (x-2)(x-3) becomes x² + 5x + 4 = x² - 5x + 6. Subtracting x² and adding 5x to both sides, we have 10x = 2 and x = 1/5. You can plug this in to check.
i hope this was helpful! :D
Step-by-step explanation:
Hey there!
Given;
(X+1) (X+4) = (x-2) (x-3)
Multiply (X+1) and (X+4) on left side and (x-2) and (x-3) on right side.
[tex] {x}^{2} + 4x + x + 4 = {x}^{2} - 3x - 2x + 6[/tex]
Simplify it.
[tex]5x + 4 = - 5x + 6[/tex]
[tex]10x = 6 -4[/tex]
[tex]x = \frac{2}{10} [/tex]
Therefore, x= 1/5.

Alex went to the store to buy supplies for peanut butter and jelly sandwiches for his birthday party. He bought bread for $3.29 for each loaf, peanut butter for $2.99 per jar and jars of jelly. The total cost was $23.64. If Alex bought three of each item, what was the cost of one jar of jelly?
1. Define the variable. =
2. Equation to be solved =
3. One jar of jelly cost =
Answer:
Define the variable: The variable is the cost of one jar of jelly
Equation to be solved: Refer to Step by Step
One jar of jelly cost: 1.60
Step-by-step explanation:
total bread cost: 9.87
total peanut butter cost: 8.97
total jelly cost: x
so 23.64 - (9.87 + 8.97) = x
simplified: 23.64 - 18.84 = x
even more simplified: 4.80 = x
so 3 jars of jelly is 4.80
so divide
4.80 divided by 3 = 1.6
so one jar of jelly costs 1.6
