Step-by-step explanation:
The equation d=65t models the distance, d, that Malcolm's family travels after t hours. 10 miles per hour 15 miles per hour 30 miles per hour 65 miles per hour
The question is incomplete. Here is the complete question.
Malcolm and Theo's families are both traveling to the same vacation resort. The equation d = 65t models the distance, d, that Malcolm's family travels after t hours.
The graph below shows the relationship between the distance and the amount of time that Theo's family traveled.
How much faster did Malcolm's family travel than Theo's family?
a) 10 miles per hour
b) 15 miles per hour
c) 30 miles per hour
d) 65 miles per hour
Answer: b) 15 miles per hour
Step-by-step explanation: Speed is given by the change in distance per change in time or:
[tex]v=\frac{\Delta x}{\Delta t}[/tex]
For Theo's family, the graph shows the change in miles is constant in hours, so, the speed they are traveling is
[tex]v_{T}=\frac{200-0}{4-0}[/tex]
[tex]v_{T}=\frac{200}{4}[/tex]
[tex]v_{T}=[/tex] 50 mph
For Malcolm's family:
At t = 0: d = 65*0 = 0
At t = 4: d = 65*4
Then, Speed is:
[tex]v_{M}=\frac{65*4-0}{4-0}[/tex]
[tex]v_{M}=\frac{65.4}{4}[/tex]
[tex]v_{M}=[/tex] 65 mph
Theo travels at 50 mph and Malcolm at 65 mph, therefore, Malcolm is 15 miles per hour faster than Theo
Solve for b: 4b + 8/ -2 = 10
Answer:
The answer is b= 7/2
Step-by-step explanation:
hope this helps
Answer:
Step-by-step explanation:
4b-4+4=10+4
4b=14
4b/4 =14/4
B=7/2
Given the slope and point that passes through the line, write the equation in point-slope and slope-intercept forms.
through: (1,5), slope = 4
Step 1: Determine b using slope-intercept form*, the given point, and the given slope.
[tex]5 = 4(1) + b\\\\5 = 4 + b\\\\1 = b[/tex]
Step 2: Use b and m (or slope) to write the equation of the line in point-slope form** and slope-intercept form*.
[tex]y = 4x + 1\\\\y - 5 = 4(x - 1)[/tex]
*Slope-intercept form: y = mx + b
**Point-slope form: y - y₁ = m(x - x₁)

A deck of cards has 52 cards, half of them are red, a fourth of them are diamonds. What is the probability I select a diamond with one pull?
Answer:
1 fourth of 52 is 13 so i think its 13 tell me if ibam wrong
Answer:
There is a 33% percent chance.
Step-by-step explanation:
You could use the formula, desired probability out of total outcome options
So basically, it would be 52/3 to get how much a fourth of the cards are, which is 13
13/52=0.25*100=25%

Answer:
Hebrew National since the cost is only 0.73
Step-by-step explanation:
First we need to identify the cost of each hotdog for each brand. I'll go by in order.
Ball Park:
We know that it cost $6.95 and it's 8 dogs for each one. Meaning all we have to do is divide the price by the amount of hot dogs.
"Price/Hotdogs per package"
In order
6.95/8=0.86875 or 0.87
8.20/10=0.82
7.35/8=0.91875 or 0.92
17.50/24=0.7291666 or 0.73
Since we're dealing with currency we would most likely round it by the nearest hundredth so the true answer would be $0.87.
Use this formula that I made for this question for any other questions.

Your bank pays 4% annual interest compounded quarterly on January 1, April 1, July 1, and October 1. You deposited $840 on April 1 and made no other deposits or withdrawals. Find your savings account balance on January 1 of the next year.

Your bank pays 4% annual interest compounded quarterly on January 1, April 1, July 1, and October 1. You deposited $840 on April 1 and made no other deposits or withdrawals. How much interest did you earn for these nine months?
Answer:
The interest earned in 9 months is $25.45284
Step-by-step explanation:
The interest rate given by the bank = 4%
The rate at which the interest is applied = Quarterly
The amount of money deposited = $840
The formula for compound interest is given as follows;
[tex]Compound \ interest = P \times \left [ \left(1 + \dfrac{r}{n} \right )^{t \times n} - 1\right ][/tex]
Where;
P = The principal = $840
r = The rate = 4% = 0.04
n = The number of times the interest is compounded per period = quarterly = 4
t = The time duration in period = 9 months = 3/4 × 1 year
Substituting the values gives the Compound interest C.I. as follows;
[tex]C.I. = 840 \times \left [ \left(1 + \dfrac{0.04}{4} \right )^{\dfrac{3}{4} \times 3} - 1\right ] = 840 \times \left [ \left(1 + \dfrac{0.04}{4} \right )^{ 3} - 1\right ] = \$ 25.45284[/tex]
The interest earned in 9 months = $25.45284.

Find an equation for the perpendicular bisector of the line segment whose endpoints are (−3,4) and (−7,−6).
Answer:
[tex]y=-\frac{2}{5}x-3[/tex]
Step-by-step explanation:
First, you must find the midpoint of the segment, the formula for which is [tex](\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})[/tex]. This gives you (-5,-1) as the midpoint. This is the point at which the segment will be bisected.
Next, since we are finding a perpendicular bisector, we must determine what slope is perpendicular to that of the existing segment. To determine the segment's slope, we use the slope formula [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex], which gives us a slope of [tex]\frac{5}{2}[/tex].
Perpendicular lines have opposite and reciprocal slopes. The opposite reciprocal of [tex]\frac{5}{2}[/tex] is [tex]-\frac{2}{5}[/tex].
We now know that the perpendicular travels through the point (-5,-1) and has a slope of [tex]-\frac{2}{5}[/tex].
Solve for [tex]b[/tex] in [tex]y=mx+b[/tex].
[tex]y=mx+b\\-1=-\frac{2}{5}(-5)+b\\-1=2+b\\-3=b\\b=-3[/tex]
Therefore, the equation of the perpendicular bisector is [tex]y=-\frac{2}{5}x-3[/tex].

In triangle DEF, segment DJ is a perpendicular bisector of side EF. If EJ is 3y-8 and JF is 7y-40, what is the length of JF?
Answer: The length of JF = 16 units.
Step-by-step explanation:
Given: In triangle DEF, segment DJ is a perpendicular bisector of side EF.
i.e. DJ is perpendicular to EF and DJ divides EF into two equal parts EJ and JF. [The perpendicular bisector is a line that is perpendicular to a line segment and splits it into two congruent segments.]
If EJ is 3y-8 and JF is 7y-40.
Then, [tex]3y-8=7y-40[/tex]
[tex]\Rightarrow\ 7y-3y=40-8\\\\\Rightarrow\ 4y=32\\\\\Rightarrow\ y=8 \text{ [Divide both sides by 4]}[/tex]
JF= 7(8)-40 =56-40= 16 units
Hence, the length of JF = 16 units.

Answer:
C) y = 10/3x - 5
Step-by-step explanation:
Slope intercept equation is y = mx + b:
m is the slope
b is y-intercept
When you read slope you can also read it as rise over run. Rise is move up or down on the y axis depending if number is negative or positive. Run is move left or right on x axis depending if number is negative or positive.
Example: y = [tex]\frac{10}{3} x - 5[/tex]
Start at the y-intercept which is -5. On graph you can see the line crosses the y axis at (0, -5). From this point rise 10 then run 3 you'll end up at point (3, 5). Connect the dots of the two points and you'll see a line like the one in the problem.

An albatross is a large bird that can fly 400 kilometers in 8 hours at a constant speed. What are two constants of proportionality for the relationship between distance in kilometers
Answer:
50Step-by-step explanation:
Given
Distance covered by the bird = 400km
Time taken = 8 hours
Using the formula;
Speed = Distance/Time
S = d/t
Find the speed first:
S = 400km/8hr
S = 50km/hr
Substitute back into the formula:
S = d/t
50 = d/t
50t = d
d = 50t
This means that the distance d is directly proportional to the time with 50 as the constant of proportionality.
Hence the constant of proportionality for the relationship between distance in kilometers is 50.

are real numbers closed under cube root?
Answer:
Real numbers are not closed under cube root
Step-by-step explanation:
The cube of each real number is increasing as the real numbers increases, giving a functional or one to one relationship. Therefore, the cube roots of real number have also a one to one relationship.
Given that a cube root of a number, ∛x = y therefore, y³ = x, we have that all real numbers, excluding zero, have one cube root, and two complex and conjugate roots
For the real number, 8, we have the cube roots given as follows;
∛8 = 2
Also, ∛8 = -1 + √3i and -1 - √3i
Given that not all cube roots of 8 are real numbers we have that real numbers are not closed under cube root.
