Answer:
the time needed to get to the arch is 6 per hour
Step-by-step explanation:
The computation of the time needed to get to the arch is shown below:
As we know that
Speed = distance ÷ time
where,
Speed is 65 miles per hour
And, the distance is 390 miles
So, the time is
= 390 ÷ 65
= 6 per hour
Hence, the time needed to get to the arch is 6 per hour
We simply applied the above formula so that the correct value could come

Write the equation of the line fully simplified slope-intercept form. help
Answer:
y = 4x -8
Step-by-step explanation:
The y intercept is -8 so our b term for y = mx + b is 8.
The line goes up 4 y values every one x value to the right
Answer:
y = 3x - 8
Step-by-step explanation:
To write the equation of the line in slope-intercept form, or y = mx + b, we have to find the y-intercept (b) and the slope(m).
To find the y-intercept, look at the graph at find where the line intercepts the y-axis. On this graph, the line intercepts at y = -8. Now we know the value of b.
To find the slope, look at the rise over run between two points. The line goes up by 3 every time it goes over 1. this means that our slope is 3.
Now we can input the values of the slope and the y-intercept into the equation.
y = 3x - 8

Write an expression for the sequence of operations described below. add b to a, then multiply 9 by the result Do not simplify any part of the expression.
Answer:
9a+9b
Step-by-step explanation:
Add b to a and multiply 9 by the result without simplifying any part of the expression.
Not simplifying an expression in algebra means not organizing or grouping like terms in the algebraic expression in such a way as to make it more understandable. It is not required in this case. Hence,
We add b to a
=a+b
We multiply 9 by the result
=9 * a+b
=9(a+b)
= 9a+9b

The base of an isosceles triangle is a third as long as the two equal sides (each, not
combined). Write the perimeter of the triangle as a function of the length of the base.
Answer:
The perimeter is 7b
Step-by-step explanation:
An isosceles triangle has exactly two sides of the same length. Suppose we have an isosceles triangle with the base as the unequal side length of b.
The perimeter of the triangle is:
P = x + x + b = 2x + b
Being x the two equal side lengths.
It's given the base b of the triangle is one-third of any of the other sides, that is:
b = 1/3 x
Or, equivalently:
x = 3b
Thus, the perimeter of the triangle is:
P = 2x + b = = 2(3b) + b
P = 6b + b = 7b
The perimeter is 7b

There are two polygons. The larger one has three times as many sides as the smaller one.
Its angle sum is four times as big. How many sides does the smaller polygon have?
Answer:
Step-by-step explanation:
There are two polygons. The larger one has three times as many sides as the smaller one. Its angle sum is four times as big. How many sides does the smaller polygon have? (Need full solution)?
“Three times as many sides” means the larger polygon has a multiple of 3 sides. 3 is the fewest sides any polygon can have, so it has not less than 9 sides.
Its angle sum is four times the smaller one’s. This applies to interior angles.
A triangle’s sum is 180. A square’s is 360. A pentagon’s is 540. Any sum will be a multiple of 180, and equal to the number of sides minus two, then multiplied by 180.
A hexagon has 6 sides, so 4×180=720 degrees sum. That part fits the triangle, but we know that can’t be the answer because 3×3=9.
So start at 9.
7×180÷4 can’t be a multiple of 180. What we need is a multiple of 3 which is 2 greater than a multiple of 4.
18 fits that description.
The 18-gon’s interior sum is 16×180=2880, divide that by 4 to get 720, which is the hexagon’s sum.
18÷6=3, so we have a solution. The smaller polygon can be a hexagon.
We should check the next one though. Multiples of 3: 21, 24, 27, 30, 33, 36, 39, 42 (every 4th multiple of 3 will be 2 more than a multiple of 4).
So the 30-gon:
28×180=5040
5040÷4=1260
1260÷180=7
7+2=9
9×3=27
Off by 3.
The 42-gon:
((((((42–2)×180)÷4)÷180)+2)×3)=36
Off by 6. It will keep getting farther away, so we have a unique solution.

If h(x) = 5 for the function h(x) = 2x + 1, what is the value of x?
12
11
2
Answer:
x = 2 .
Step-by-step explanation:
Given : If h(x) = 5 for the function h(x) = 2x + 1, .
To find : what is the value of x?
Solution : We have given
h(x) = 5 for the function h(x) = 2x + 1,
Now plug the h(x) = 5.
2x + 1 = 5 .
On subtracting both sides by 1
2x = 5 -1 .
2x = 4
On dividing both sides by 2 .
x = 2 .
Therefore, x = 2 .

A balalaika is a Russian stringed instrument. Show that the triangular parts of the two balalaikas are congruent for x = 6.
*the diagram of the Russian stringed instrument is attached below.
Answer/Step-by-step explanation:
To show that the traingular parts of the two balalaikas instruments are congruent, substitute x = 6, to find the missing measurements that is given in both ∆s.
Parts of the first ∆:
WY = (2x - 2) in = 2(6) - 2 = 12 - 2 = 10 in
m<Y = 9x = 9(6) = 54°.
XY = 12 in
Parts of the second ∆:
m<F = 72°
HG = (x + 6) in = 6 + 6 = 12 in
HF = 10 in
m<G = 54°
m<H = 180 - (72° + 54°)
m<H = 180 - 126
m<H = 54°
From the information we have, let's match the parts that are congruent to each other in both ∆s:
WY ≅ FH (both are 10 in)
XY ≅ GH (both are 12 in)
<Y ≅ <G (both are 54°)
Thus, since two sides (WY and XY) and an included angle (<Y) of ∆WXY is congruent to two corresponding sides (FH and GH) and an included angle (<G) in ∆FGH, therefore, ∆WXY ≅ ∆FGH by the Side-Angle-Side (SAS) Congruence Theorem.
This is enough proof to show that the triangular parts of the two balalaikas are congruent for x = 6.
A 20 inch long piece of rope is approximately 0.5 meters long. What is the length, in inches, of a rope that is 2.5 meters long, rounded to the nearest tenth?
Answer:
100 inches (using the given data)
98.43 (using exact numbers)
Step-by-step explanation:
1 inch = 2.54 centimeters
20 inches = 50.8 centimeters, but for the purpose of answering this question we will assume that 20 inches = 0.5 meters (instead of 0.58).
we must solve the following equation:
20 inches / 0.5 meters = X inches / 2.5 meters
(2.5 meters x 20 inches) / 0.5 meters = X inches
20 inches x 5 = X inches
100 inches = X inches
if we do the exact calculation, 2.5 meters in inches = 250 centimeters / 2.54 centimeters per inch = 98.43 inches
Consider the scale drawing and actual drawing of an office.
A smaller rectangle has a length of 2.5 inches and width of 1.5 inches. A larger rectangle has a length of 5 yards and width of 3 yards.
Compare the scale drawing to the actual drawing. What information is needed to find the area?
1. The scale factor is
.
2. The area of the scale drawing is
.
3. To find the area of the actual drawing, multiply the area of the scale drawing by the
of the scale factor.
a)Scale factor is 72.
b)The area of the scale drawing is 3.75 square inches.
c)To find the area of the actual drawing, multiply the area of the scale drawing by 5184.
Length of the smaller rectangle =2.5inches
Width of the smaller rectangle = 1.5inches
So, the area of the smaller rectangle = 2.5*1.5 = 3.75 square inches.
Length of larger rectangle = 5 yards
Width of larger rectangle =3 yards
So, the area of the larger rectangle = 15 square yards = 15*36*36 = 19440 inches.
What is the scale factor?The scale factor is the factor by which the dimension of an object is enlarged.
a)Scale factor = dimension of the larger rectangle/ corresponding dimension of the smaller rectangle
Scale factor = 5 yards/ 2.5 inches
as we know that 5 yards equals 180 inches
So, scale factor = 180/2.5 = 72
b)The area of the scale drawing = 3.75 square inches.
c)Area of actual drawing/ area of scale drawing = 19440/3.75 = 5184
So, to find the area of the actual drawing, multiply the area of the scale drawing by 5184.
therefore, a)Scale factor is 72
b)The area of the scale drawing is 3.75 square inches.
c)To find the area of the actual drawing, multiply the area of the scale drawing by 5184.
