The two rectangles are scale drawings. What is the
measurement of x?
Answer:20
Step-by-step explanation:
7 divided by 28 is 4 so multiply 5x4
Answer: is 20
Step-by-step explanation:
Which table shows a proportional relationship between x and y?
Its the first answer because 7 divided by 1 = 7, 14 divided 2= 7, 28 divded 4 = 7
35 divided by 5 equals to 7
Its constant the number stays the same
The sum of two numbers is 20. Their difference is 4.
a. Write a system of equations that describe this situation
b. Solve by elimination to find the two numbers
Answer:
The two numbers are 12 and 8
Step-by-step explanation:
Well this is pretty simple
We can just list out everything that Adds up to 20
1+19
2+18
3+17
4+16
5+15
6+14
7+13
8+12
9+11
10+10
Now just subtract each one until you get the one that equals to 4
Which is 12 and 8 in this case
Write the equation, in slope-intercept form, of the line that passes through (-2,0) and is parallel to the line represented by 5x-3y=-17 .
Answer:
[tex]y=\frac{5}{3}x+\frac{10}{3}[/tex]
Step-by-step explanation:
Firstly we rewrite the equation that is parallel to the line we need because parallel lines have the same slope by the rule
[tex]m_1=m_2[/tex]
so we rewrite the equation in slope-intercept form:
[tex]5x-3y=17\\-3y=-5x+17\\y=\frac{-5x+17}{-3}\\\\y=\frac{-5x}{-3}+\frac{17}{-3} \\\\y=\frac{5}{3}x-\frac{17}{3}[/tex]
and now we compare it with our slope-intercept form equation:
[tex]y=mx+b[/tex]
the coefficient of x which is m is the slope and since parallel lines have equal slopes the line that we need would also have the same slope which is 5/3.
now the next step is the line that we need passes through the point (-2,0) so it means that it should satisfy that specific point so we insert that point into our slope-intercept form and insert the slope which is 5/3 which is m.
[tex]y=mx+b\\y=\frac{5}{3}x+b\\\\0=\frac{5}{3}(-2)+b\\\\0=\frac{-10}{3}+b\\\\b=\frac{10}{3}\\[/tex]
now we know that the y-intercept(b) of the line we need is 10/3 and slope(m) is 5/3 insert these values into our slope-intercept form:
[tex]y=mx+b\\y=\frac{5}{3}x+\frac{10}{3} \\[/tex]
so this is our given line.

Step-by-step explanation:
A basketball costs $32.00. The sales tax rate is 7%. Find the amount of sales tax
The amount of the sales tax is $2.24.
Given that,
The cost of the basketball is $32.00And, the sales tax rate is 7%.Based on the above information, the amount of the sales tax rate is
[tex]= \$32 \times 7\%[/tex]
= $2.24
Here we simply multiply the cost with the sales tax rate.
Therefore we can conclude that the amount of the sales tax is $2.24.

A. Yes; the graph passes the vertical line test.
B. No; there are y-values that have more than one x-value.
C. Yes, there are no y values that have more than one x-value.
D. No; the graph fails the vertical line test.
Answer:
D. No; the graph fails the vertical line test
The correct option is D. No, the graph fails the vertical line test.
What is vertical line test?The vertical line test is a graphical method of determining whether a curve in the plane represents the graph of a function. It is done by visually examining the number of intersections of the curve with vertical lines.
In the given graph, the graph of a function intersects the y axis twice.
Any vertical line in the x y plane must intersect the graph of a function at most once.
Thus, the correct option is D.

Lucas took his bike to a local park to ride on some bike trail.Trail A is 6 3/4 miles long.Trail B is 8 1/2 miles long. How many miles long is Trail B then Trail A
Answer: Trial B is [tex]1\dfrac{3}{4}[/tex] miles longer then Trail A.
Step-by-step explanation:
Length of Trail A = [tex]6\dfrac34[/tex] miles
= [tex]\dfrac{24+3}{4}[/tex] miles = [tex]\dfrac{27}{4}[/tex] miles.
Length of Trail B = [tex]8\dfrac12[/tex] miles
= [tex]\dfrac{16+1}{2}[/tex] miles = [tex]\dfrac{17}{2}[/tex] miles.
Trial B is longer then Trail A by [tex]\dfrac{17}{2}-\dfrac{27}{4}[/tex] miles
[tex]=\dfrac{17\times2}{2\times2}-\dfrac{27}{4}[/tex] miles
[tex]=\dfrac{34}{4}-\dfrac{27}{4}[/tex] miles
[tex]=\dfrac{7}{4}[/tex] miles
[tex]=1\dfrac{3}{4}[/tex] miles
Hence, Trial B is [tex]1\dfrac{3}{4}[/tex] miles longer then Trail A.

The length of a side of a regular hexagon is 6.8 cm, correct to one decimal place. Find the smallest possible perimeter of the length
Answer: 40.8cm
Step-by-step explanation:
A hexagon is a polygon that is made up of 6 sides. The perimeter of a regular hexagon is calculated by multiplying the side given by 6
Since the length of a side of a regular hexagon is 6.8 cm, the perimeter will be:
= 6 × 6.8
= 40.8cm

Cesar has 32 boxes of pasta and 48 jars of sauce that he will be putting into bags for a food drive. He wants each bag to have the same amount of pasta and sauce and wants to use all of the items. Use the drop-down menus to complete the statements below about the number of bags Cesar can make.
What is the greatest number of bags Cesar can make and Each bag would have _____ pasta and _____ jars of sauce
Answer:
The greatest number of bags Cesar can make is 16 bags.
Each bag would have 2 pasta and 3 of jars of sauce
Step-by-step explanation:
We solve the above question using Greatest Common Factor method
The factors of 32 are: 1, 2, 4, 8, 16, 32
The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
Then the greatest common factor is 16.
Hence, the greatest number of bags Cesar can make is 16 bags.
For Pasta, We have 32 pasta
Each bag would have: 32/16
= 2 pasta
For Jars of sauce, we have 48 jars of sauce.= 48/16
= 3 jars of sauce
PLEASE HELP HELP!!! PRECALC
Answer:
The base is 0.1
The base is less than 1 so the function is decreasing
The x intercept is (3,0)
Step-by-step explanation:
The base of a logarithm refers to the number that must be raised to the power of the number on the right hand side of the logarithmic equation in order to yield the number on the left hand side of the logarithmic equation. It is always written as a subscript below the log symbol. In this case, the base is 0.1.
When the base of a logarithm is less than 1, it means that the function is decreasing as is the case in this question.
Looking at the graph, the x axis is cut at the point (3,0). This is the x-intercept of the graph.
A rectangle and an equilateral triangle have the same perimeter. The perimeter of the rectangle is 6 ( 1 2 x + 5 ) inches. The perimeter of the triangle is 4 ( x − 2 ) inches. What is the perimeter of each figure?
Answer:
-328/34
Step-by-step explanation:
Here,
Perimeter of rectangle = 6(12x+5)
Perimeter of equilateral triangle = 4(x-2)
Since they are equal, 6(12x+5) = 4(x-2)
or, 72x + 30 = 4x - 8
or, 68x = -38
or, x= -38/68 or -19/34
Now,
Area of triangle ( or rectangle whichever you prefer)
= 4* -19/34 - 8
= -76/34 - 8
= - 328/34

Susan got 72 marks in English out of 120 and 70 marks in
Hindi out of 150. The maximum marks in the mathematics
paper were 180. If she got 60% marks in all the three papers
how y marks did she get in mathematics?
Answer:
let the marks obtained in maths be x
total marks obtained by susan=142+x
then
A/Q
60%of 450 =(142+x)
270=142+x
x=270-142
x=128
hence marks obtained in maths=128
OR
Max marks 120+150+180=450
60% of 450 is 270
70 +72+x=270
x=270-142
x=128
