DannyStep-by-step explanation:
Danny's speed is given:
15 mphAndrew's speed is found from the table.
Since its the direct relationship, we find it using one pair of values:
Speed = miles/times = 21.75/1.5 = 14.5 mphDanny is faster as 15 mph > 14.5 mph
Speed =Distance/Time
Here speed is equal to slope of box
m=y/xm=29/2m=14.5mphDanny is faster as his one is 15mph

Determine if the following is Infinite solutions, one solution, or no solutions
x+y=4

Answer:
30
Step-by-step explanation:
infinite solutions cause when you take out the 2 from the bottom equation, you get x + y = 4, which is the exact same equation as the first one, so literally any two values will result in the same for both
Grace and her brother need $400 to go to band camp. Their parents have agreed
to help them earn money by paying them $25 each time they mow the lawn
and $10 for each hour they babysit their younger brother. They will have to do a
combination of both chores to earn the money.
Select the equation that represents the number of lawns they can mow, m, and
hours they can babysit, b, to earn $400.
M. 10m + 25b = 400
P.
10m - 25b = 400
R. 25m + 10b = 400
S. 25m - 10b = 400
Answer:
R. 25m + 10b = 400
Step-by-step explanation:
25m: $25 for time the mow the lawn
10b: $10 for every hour that they babysit their younger brother
400: They need $400 in total
+ : You need to add what they made for mowing the lawn and for babysitting.
We are going to fence in a rectangular field that encloses 75 ft2. Determine the dimensions of the field that will require the least amount of fencing material to be used.
Answer:
For width W and length L, we have:
W = L = √(75ft^2) = 8.66ft
Step-by-step explanation:
For a rectangle of length L and width W, the area is:
A = L*W
and the perimeter is:
P = 2*L + 2*W
First, we know that the area of our rectangle is:
A = 75ft^2 = L*W
And we want to minimize the perimeter of our rectangle, then we need to minimize:
P = 2*L + 2*W
From the equation:
75ft^2 = L*W
We can isolate one of the variables, let's isolate L
L = (75ft^2)/W
We could replace this in the perimeter equation:
P(W) = 2*( (75ft^2)/W) + 2*W
P(W) = (150 ft^2)/W + 2*W
To find the minimum of the perimeter we need to look at the zero of the first derivative of P(W).
P'(W) = dP(W)/dW = -(150ft^2)/W^2 + 2
Now we need to find the value of W such that:
P'(W) = 0
0 = -(150ft^2)/W^2 + 2
(150 ft^2)/W^2 = 2
(150ft^2) = 2*W^2
(150ft^2)/2 = W^2
75 ft^2 = W^2
√(75ft^2) = W = 8.66ft
And remember that:
L = (75ft^2)/W
replacing with W = √(75ft^2)
L = (75ft^2)/√(75ft^2) = √(75ft^2)
Then:
W = L = √(75ft^2) = 8.66ft
find the angle of 1 and 3
Answer:
Angle of 1 and 3 as 90*
Step-by-step explanation:
This is because all angles are the same meaning all angles are 90*. Even 1 and 3. Brainiest and a thank you?!
Answer:
We really aren't provided with enough information to give you the answer. I'll explain how to find them, but you should comment on my response and tell be if it gives you any values at all to work with.
So, ∠1 and ∠3 are vertical angles, which means they are equal to each other.
Along with that, ∠2 and ∠4 and also vertical angles, so they're equal to each other as well.
Now we have the information:
∠1 = ∠3
and
∠2 = ∠4
__________________________________________________________
Given that both of the two lines are intersecting, each angle has two angles that it is supplementary to.
Supplementary angle are angles that when added together equal exactly 180°.
A perfectly straight line's angle it 180°.
Using this knowledge, you can find that ∠1 is supplementary to ∠2, ∠2 is supplementary to ∠3, ∠3 is supplementary to ∠4, and ∠4 is supplementary to ∠1.
If that's still confusing, here's it explained simpler:
∠1 + ∠2 = 180°
∠2 + ∠3 = 180°
∠3 + ∠4 = 180°
∠4 + ∠1 = 180°
__________________________________________________________
But still - you haven't given us the information to find these values. Are you given even one angle measurement to work with?? If so, comment it here and I'll work it out for you.

Answer:
x= 4 and y=1
Step-by-step explanation:
to solve this you could either use substitution or elimination. elimination would be best her because both 'x's have the same number. subtract the equations from eahh other and solve for y, then substitute the y and solve for x
The system of equations are solved and x = -4 and y = 1
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
To solve the system of equations:
5x + y = -19 (Equation 1)
5x - 4y = -24 (Equation 2)
Let's use the elimination method in this case.
Step 1: Multiply Equation 1 by 4 and Equation 2 by 1 to eliminate y.
4(5x + y) = 4(-19)
5x - 4y = -24
20x + 4y = -76 (Equation 1 multiplied by 4)
5x - 4y = -24 (Equation 2 multiplied by 1)
Step 2: Add the equations together to eliminate y.
20x + 4y + 5x - 4y = -76 - 24
25x = -100
x = -100 / 25
x = -4
Step 3: Substitute the value of x into either Equation 1 or Equation 2 to solve for y.
5(-4) + y = -19 (Using Equation 1)
-20 + y = -19
y = -19 + 20
y = 1
Hence , the solution to the system of equations is x = -4 and y = 1

The line of best fit is:
y = 3.1x + 12.9
Option A is the correct answer.
We have,
The line of best fit can be expressed in the form of y = ax + b,
where a is the slope of the line and b is the y-intercept.
From the given LinReg results, we have:
a = 3.1
b = 12.9
Substituting a and b in the equation y = ax + b we get,
The line of best fit is:
y = 3.1x + 12.9
Thus,
The line of best fit is:
y = 3.1x + 12.9

Luis is making cookies. He needs 1 1/4 cup of sugar to make 12 cinnamon cookies and 1/2 cups of sugar to make 24 chocolate chip cookies. How many cups of sugar does he need to make both recipes?
Answer: 1 3/4 cups of sugar
Step-by-step explanation:
To make the first recipe, Luis needs 1 1/4 cup of sugar.
To make the second recipe, he needs 1/2 cup of sugar.
The number of cups of sugar that he need to make both recipes will be gotten by adding both cups of sugar together. This will be:
= 1 1/4 + 1/2
= 1 1/4 + 2/4
= 1 3/4
Therefore, 1 3/4 cups of sugar are needed

Which fee could decrease an investor's return on investment when the investor may not have bought or sold any stock for a significant period of
time?
OA front-end load
Answer: Inactivity fee
Step-by-step explanation:
The rest of the options are not given but there can only be one correct answer to this question and that's the answer above.
Brokerages earn a return when they trade financial instruments for investors as they take a commission from this. When an investor has not traded for a while, brokerages don't get to make earnings and will be holding the account with minimal rewards.
To compensate for this, they charge an inactivity fee that will ensure that they get some form of earnings for managing the account and not receiving commission.
