Answer: [tex]\frac{1}{2}\ \text{of}\ 130> 20\%\ \text{of}\ 320[/tex]
Step-by-step explanation:
[tex]20\%\ \text{of}\ 320\ \text{is}\\\Rightarrow \frac{20}{100}\times 320=64\ \text{miles}[/tex]
[tex]\frac{1}{2}\ \text{of}\ 130\ \text{is} \\\Rightarrow \dfrac{130}{2}=65\ \text{miles}[/tex]
clearly, [tex]\frac{1}{2}\ \text{of}\ 130> 20\%\ \text{of}\ 320[/tex]

Answer:
The scale Myra should use is one graph unit = 400 km or;
←--→ = 400 km
Step-by-step explanation:
The question relates to the representation of scale drawing
The actual distance between Perth and Sydney = 3294 kilometers
The given coordinates of Perth on the grid = (1.3, 3.4)
The given coordinates of Sydney on the grid = (9.2, 3.3)
The measure of the distance between Perth and Sydney, 'd', is given by using the following formula for finding the distance between two points given their 'x', and 'y' coordinates;
[tex]d = \sqrt{\left (x_{2}-x_{1} \right )^{2}+\left (y_{2}-y_{1} \right )^{2}}[/tex]
Therefore, by substitution, we have;
[tex]d = \sqrt{\left (9.2-1.3 \right )^{2}+\left (3.3-3.4 \right )^{2}} = \sqrt{\left (7.9 \right )^{2}+\left (-0.1 \right )^{2}} = \dfrac{\sqrt{6242} }{10} \approx 7.9[/tex]
d ≈ 7.9 units
Therefore, we have;
7.9 units of the graph = 3294 kilometers
1 unit of the graph ≈ 3294/7.9 km = 416.962025316 km ≈ 416.96 km
Therefore, the scale Myra should use for her map is 1 unit = 400 km.

The two fractions when multiplied together make 3/4 are, 1/2 and 3/2.
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
The first fraction can be 1/2 when multiplied by the second fraction 3/2.

The following graphs are transformations of f(x) = x^2.
Complete the boxes below to describe the transformations.
A(x) = f (x + _) + _
B(x) = f (x + _) + _
C(x) = f (x + _) + _
D(x) = f (x + _) + _
Step-by-step explanation:
Let's look at A(x) and see how it is different from f(x)
it is shifted downwards by 8 unitsit is not shifted to the left or the rightTherefore A(x) = f(x) - 8
Let's look at B(x) and see how it is different from f(x)
it is not shifted downwards or upwardsit is shifted to the left 7 unitsTherefore B(x) = f(x + 7)
Let's look at C(x) and see how it is different from f(x)
it is shifted upwards by 4 unitsit is shifted to right by 5 unitsTherefore C(x) = f(x - 5) + 4
Let's look at D(x) and see how it is different from f(x)
it is not shifted downwards or upwardsit is not shifted to right by 12 unitsTherefore D(x) = f(x - 12)

Find the measure of
Answer:
19 degrees.
Step-by-step explanation:
First solve the angles in the top triangle:
FHG = 180 - 135 = 45 (angles on a straight line = 180)
FGH = 180 - 105 = 75 (angles on a straight line = 180)
Using these we get HFG = 180 - 45 - 75 = 60 (angles in a triangle = 180)
Then because HFG is directly opposite DFC on the crossed lines, we know they are equal: DFC = 60
FDC = 180 - 119 = 61 (anges on a straight line = 180)
Now if we label ABC (the target angle) as x then we known ACB = 180 - 40 - x.
With this we know FCD = 180 - ACB = 180 - (180 - 40 - x) = 40 + x (angles on a straight line).
Finally using the FDC triangle we have 40 + x + 60 + 61 = 180 so x = 180 - 40 - 60 - 61 = 19 degrees.
Debbie bought x pens. She paid $0.75, including tax, per pen. She gave the cashier $20 and received $8.75 in change. How many pens did Debbie purchase?
Answer:
15
Step-by-step explanation:
if she gave 20$ and got 8.75$ in change, she payed 11.25$
11.25$ (total) / 0.75 (per pen)= 15 (pens she bought)

Answer:
Only one circle can be drawn through three non nonlinear points, No circle can be drawn through three nonlinear points
Step-by-step explanation:
A circle has a curve. As long as the three non nonlinear points both have the same amount of distance from the center of the circle it can be a circle drawn. No circle can be drawn through three points on the line.
A car moving on a highway covers the first 400.0 m in 18.0s and then covers the next 250.0 m in 24.0 s.
What is the average speed of the car?
Answer: 15.48 m/s
Step-by-step explanation:
The following information can be gotten from the question:
Total distance covered by the car will be:
= 400m + 250m
= 650m
Total time taken = 18.0s + 24.0s = 42s
Average speed = Distance/Time
= 650/42
= 15.48 m/s

Rectangle LMNO is reflected over the x-axis to create rectangle L'M'N'O'. If a line segment is drawn from point M to point M', which statement would best describe the relationship between segment M M prime and the x-axis?
Answer:
They are perpendicular to each other.
Step-by-step explanation:
It is given that there is a rectangle LMNO and this rectangle is reflected over x axis and the create a new rectangle L'M'N'O'.
Now if a straight line segment is drawn joining the point M to the point M', they will form perpendicular to each other. Thus The relationship between the line segment M-M' and the x axis is perpendicularity.

x/5 + 2 = 19 x______
Answer:
47x=5
or 5/47
Step-by-step explanation:
Answer:
x=85
Step-by-step explanation:
x/5 + 2 = 19
5(x/5 + 2) = 5(19) *multiply both sides of the equation by 5 to get rid of the fraction
x + 10 = 95
x = 85 *subtract 10 on both sides
Check:
x/5 + 2 = 19
85/5 + 2 = 19
17 + 2 = 19
19 = 19

Write a polynomial in standard form that represents the area of the shaded region.
Answer:
[tex]A=p^2-2p-3[/tex]
Step-by-step explanation:
The area for a triangle is given by:
[tex]\displaystyle A=\frac{1}{2}bh[/tex]
The base is p + 1 and the height is 2p - 6. Therefore:
[tex]\displaystyle A=\frac{1}{2}(p+1)(2p-6)[/tex]
Simplify the second term:
[tex]\displaystyle A=(p+1)(\frac{1}{2})(2p-6)=(p+1)(p-3)[/tex]
Distribute:
[tex]A=p(p-3)+1(p-3)[/tex]
