Answer:
The total cost of 1 belt and 1 tie is $13 and $39 respectively.
Step-by-step explanation:
Given that,
The cost of 4 belts and 5 ties is $247.
Each tie costs 3 times as much as a belt.
Let the cost of a belt is x and that of a tie is y.
ATQ,
4x + 5y = 247 ...(1)
y = 3x ....(2)
Put the value of y from equation (2) in equation (1)
4x + 5(3x) = 247
4x + 15x = 247
19x = 247
x = 13
Put the value in equation (2)
y = 3x
= 3(13)
= 39
So, the total cost of 1 belt and 1 tie is $13 and $39 respectively.

Each of Liam's neighbors pays him the same amount for walking one of their dogs. Last week, he earned $25 for
walking 4 of his neighbors' dogs. Which graph below best represents the linear relationship between x, the number of
dogs Liam walks, and y, the total amount of money he earns for walking them?
Answer:
The options are not shown, but we can craft the graph so you can find the one that matches it.
We know that:
Each neighbor pays the same, let's define this amount as A.
Last week, he walked 4 dogs, then the amount that he collected must be four times A, or:
4*A
And we know that this amount is $25, then:
4*A = $25
A = $25/4 = $6.25
Then we can write the relationship:
y = $6.25*x
where:
y = money that Liam earns.
x = number of dogs Liam walks.
The graph of this line is shown below.
Find the median: In a particular year, approximately 1.7 million people took the mathematics section of a college achievement test. Of these, 44% scored less than 490, 45% scored less than 500, 48% scored less than 510, 51% scored less than 520, and 57% scored less than 530. In what interval is the median score? The median score is in the interval â–¼(Choose one).
Answer:
the median score would be between 510 and 520
Step-by-step explanation:
The computation of the median score is shown below
In the case of the continuous probability distribution, the median value is the mid value in which the number is equal to fall to above or below it
Here
P(X = median) = 0.5 = 50%
So the median score would be between 510 and 520
Hence, the same is to be considered

is (-3,4) a solution to y=2x+2??
Answer:
NO i do not think so because you would end with a -4 not positive because a positive times a negative is a negative so (-3,4) is not a solution.

In triangle ABC, angle A is 35 and angle b is 20 select all triangle which are similar to triangle ABC.
Answer:
The similar one are 1 and 5
A. Triangle DEF where ∠D is 35° and ∠E is 20°.
C. Triangle JKL where ∠J is 35° and ∠L is 125°.
D. Triangle MNO where ∠N is 20° and ∠O is 125°.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know the sum of all the interior angles of a triangle is equal to 180°.
Given, A triangle ABC has ∠A = 35° and ∠B = 20°.
∴ ∠C = 180° - 35° - 20°.
∠C = 125°.
Triangle will be similar if every corresponding angle of different triangles has the same measure.
So, Triangles that are similar to triangle ABC is triangle DEF where ∠D is 35° and ∠E is 20°.
Triangle JKL where ∠J is 35° and ∠L is 125°.
Triangle MNO where ∠N is 20° and ∠O is 125°.

3x + y = 15 What is the solution of this system of equations? (5x+2y=-4
Answer:
x=34 y=-87 (34,-87)
Step-by-step explanation:
3x+y=15 rewrite to solve for y -----> y=15-3x
5x+2y=-4
Plug y=15-3x into 5x+2y=-4
So, 5x+2 (15-3x)=-4
Distribute: 5x+30-6x=-4
Combine like terms: 30-x=-4
Solve for x -x=-34
Solve for x x=34
Then, to solve for y, plug "x" into 3x+y=15
So, 3(34)+y=15
Distribute: 102+y=15
Solve for y y=-87
Jackson rides his bike from his home for 30 minutes at a fast pace. He stops to rest for 20 minutes, and then continues riding in the same direction at a slower pace for 30 more minutes. Sketch a graph of the relationship of Jackson’s distance from home over time.
Answer:
For the first 30 minutes, we will have a line with a given steepness, this will represent the 30 minutes riding at a fast pace.
Then he stops for 20 minutes, we will represent this with a constant line.
Then he again moves for another 30 minutes, but with a slower pace than in the first 30 minutes, then this line will be less steep than the first line.
A sketch of this situation can be seen below.

37st term: 9, 3, -3, -9, -15
Answer:
Step-by-step explanation:
The first term (a) = 9
the 37th term is what we want (n = 37)
d = - 6
t_37 = 9 + (n - 1) * (-6)
t_37 = 9 + 36 * - 6
t_37 = 9 - 216
t_37 = - 207
6.258 rounded to the nearest hundredth
Answer:
6.26
Step-by-step explanation:
Integer Part: 6
Fractional Part: 258
If the last digit in the fractional part of 6.258 is less than 5, then simply remove the last the digit of the fractional part.
If the last digit in the fractional part of 6.258 is 5 or more and the second digit in the fractional part is less than 9, then add 1 to the second digit of the fractional part and remove the third digit.
If the last digit in the fractional part of 6.258 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is less than 9, then add 1 to the first digit in fractional part and make the second digit in fractional part 0. Then remove the third digit.
If the last digit in the fractional part of 6.258 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is 9, then add 1 to the integer part and make the fractional part 00.
With 6.258, rule B applies and 6.258 rounded to the nearest hundredth is 2.26

6 Bridesmaids want to make 330 decorations for a wedding. Each
decoration takes about 2 4 minutes to make. How many hours will it take
for each person to make all the decorations?
Answer:
about 3.21 hours each
Step-by-step explanation:
First divide 330 by 6 since there are six people.
Every person needs to do 55 decorations.
I would take the average of 2-4 minutes and multiply it by 55.
55 x 3.5 = 192.5 minutes
to convert to hours divide by 60.
192.5 / 60 = 3.21
What is the inverse of the function shown( in the form of a graph)
Answer:
[tex] y = - 1x + b[/tex]
Step-by-step explanation:
The inverse of a slope is the exact opposite slope of the original. I'll show a function below where you can easily solve future problems if you need to.
[tex] - \frac{1}{m} x[/tex]
m is the slope, so for the equation above, you simply insert the original slope, being 1, in the equation.
[tex] - \frac{1}{1} x \\ - 1x[/tex]
So the inverse slope would be -1.

The original Volkswagen Beetle follows
a quadratic curve, write an equation if
the height is 5 feet long and the length
is 14 feet long. Show your work in the
sketchpads below.
Answer:
[tex]y= -\frac{5}{49}x^{2}+5[/tex]
Step-by-step explanation:
In order to solve this, we need to start by drawing a sketch of what the problem looks like (see attached picture).
From the picture, we can see that the graph of the equation should be a parabola with a vertex located at the point (0,5) and x-intercepts located at (-7,0) and (7,0) respectively.
So, there are two ways in which we can build a quadratic equation:
Standard form:
[tex]y=ax^{2}+bx+c[/tex]
or
Vertex form:
[tex]y=a(x-h)^{2}+k[/tex]
Since we already have the vertex and two points on the equation, we can directly use the vertex form. Where vertex is located at the coordinates (h,k)
So in this case: h=0 and k=5, which simplifies our equation a lot:
[tex]y=a(x-0)^{2}+5[/tex]
[tex]y= ax^{2}+5[/tex]
So we only need to find the value of a for our equation to be complete. We can use either x-intercept to find this. Let's use the point (7,0) so we get:
[tex]0=a(7)^2+5[/tex]
and now we can solve for a:
[tex]-5=49a[/tex]
[tex]a=-\frac{5}{49}[/tex]
so this completes our equation:
[tex]y= -\frac{5}{49}x^{2}+5[/tex]
whose graph looks like the one in the attached picture.
