Answer:
Gabriella need to 2.45 hours of travelling to be 410km apart from Willie.
Step-by-step explanation:
In order to make them 410km apart and the time included in it is to be found
we proceed as
Willie left the mall earlier and Gabriella left two hours before
so willie has travelled for 2 hours while Gabriella was still at the initial point
with this logic we find the hours Gabriella needs as follows
Willie Gabriella
←←←←←←←← →→→→→→→→→→
40km/h 70km/h
X hours X+2 hours
40*x+70(x+2) = 410
40x+70x + 140=410
110x=270
x=270/110
x= 2.45hrs

Answer:
14. y = x - 6
15. [tex]y = -\frac{1}{2}x-5[/tex]
Step-by-step explanation:
Slope-intercept form is y = mx + b where:
"m" is the slope
"b" is the y-intercept
"x" and "y" are points on the graph.
For each question,
Find the slope by counting rise over run between two points Find the y-intercept by where the graph hits the y-axis Substitute the slope and y-intercept into y = mx + b
14.
Slope:
Two points are (6, 0) and (7, 1).
[tex]m= \frac{rise}{run} \\=\frac{1}{1}\\= 1[/tex]
Y-intercept:
b = -6
y = 1x - 6
We don't need to write the 1.
∴ The equation is y = x - 6
15.
Slope:
Two points are (-2, -4) and (0, -5).
[tex]m = \frac{rise}{run}\\=\frac{-1}{2}[/tex]
Y-intercept:
b = -5
∴ The equation is [tex]y = -\frac{1}{2}x - 5[/tex]

Jack is walking on a trail and comes to mile mark 5. If he continues walking for another mile, what is the next mile marker he will come to"? This problem has to possible solutions. Please explain the two possible solutions in 2-3 sentences. (One-two word phrases are not accepted).
Answer:
Mile marker 4 or mile marker 6
Step-by-step explanation:
You can think of this problem as a number line problem. The number line represents the trail he's walking on. If he starts at the mile marker 5 and moves to the right one mile, he will find that the next mile marker is 6. But if he moves left, he will find that the next mile marker is 4. See attached picture.
Frank and Emily each take out a $160,000 loan for a new house. Each has to repay the loan in 20 years. Frank will pay an interest rate of 2.9% per year. His monthly payments will be $885. Because Emily has a lower credit score, she will have to pay an interest rate of 4.3% per year. Her monthly payments will be $995. How much more will a $160,000 loan cost Emily than Frank?
This loan of $160,000 costs Emily $26400 more than Frank.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
As given in the question,
Frank and Emily each take out a $160,000 loan for a new house. Each has to repay the loan in 20 years.
Frank's monthly payments will be $885.
Emily's monthly payments will be $995.
Difference of the total loan payment,
= 20×12[995 - 885]
= 240 × [110]
= $26400
Thus, this loan of $160,000 costs Emily $26400 more than Frank.

Write the ratio as a fraction in simplest form.
The proportion is given by the equation 36/12 = 3 / 1 or 3 : 1
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion equation be represented as A
Now , the equation will be
Let the first number be represented as p = 36
Let the second number be represented as q = 12
Now , the proportion A = p / q
Substituting the values in the equation , we get
A = 36 / 12
On simplifying the equation , we get
A = 3 / 1
Therefore , the value of A is 3 : 1
Hence , the proportion is 3 : 1

Each of the four shapes represents a positive whole number. The sum of the shapes in each row and column is displayed at the end of each row and column. Using this information, determine the numerical value of each shape.
9514 1404 393
Answer:
A = pentagon = 6
B = 5-pointed star = 8
C = rectangle = 4
D = spiral = 3
Step-by-step explanation:
Starting in the upper left corner, name the shapes A, B, C, D clockwise in the 2×2 square in that corner. Then we have ...
A = pentagon
B = 5-pointed star
C = rectangle
D = spiral
__
It turns out to be convenient to look at rows and columns with two of each shape.
Row 2: 2(C+D) = 14 ⇒ C+D = 7
We can use that in column 2 to find B:
B +C +B +D = 23 ⇒ 2B +(C+D) = 23 ⇒ 2B = 16 ⇒ B = 8
This lets us find D:
Row 4: 3D +B = 17 ⇒ 3D +8 = 17 ⇒ 3D = 9 ⇒ D = 3
So, C can now be found:
C+D = 7 ⇒ C +3 = 7 ⇒ C = 4
Finally, we can find A:
Row 1: A +2B +D = 25 ⇒ A +2(8) +3 = 25 ⇒ A = 6
__
In summary, the numerical values are ...
A = pentagon = 6
B = 5-pointed star = 8
C = rectangle = 4
D = spiral = 3

The equation correctly applies the Pythagorean Theorem is x² + 16² = 20 ².
What is Pythagoras Theorem?
If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
|AC|^2 = |AB|^2 + |BC|^2
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
Let's recall the Pythagorean theorem formula:
a² + b² = c²
Replacing by the values we have;
x² + 16² = 20 ²
Therefore, the correct answer is B.
The equation correctly applies the Pythagorean Theorem is x² + 16² = 20 ².
