Division is one of the four fundamental arithmetic operations. The typing speed of Yousef is 54 words per minute.
What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that Yousef typed a 36-word paragraph in 2/3 minutes. Therefore, the typing speed of Yousef in a minute is,
Typing speed of Yousef = 36 words/ (2/3) minutes
= (36×3)/2 words per minute
= 54 words per minute
Hence, the typing speed of Yousef in a minute is 54 words per minute.

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

To ride a roller coaster, a visitor must not be less than 50 inches tall.
Use h to represent the height (in inches) of a visitor able to ride.
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

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 .

Allan has to make a delivery that is 1200 miles away. by law, he can only drive his truck for 20 hours without taking a break. What must allan's average speed be if he wants to make the delivery before he has to take a break?
Answer:
Step-by-step explanation:
60 average speed
The delivery must be completed by Allan before he needs to stop, thus his average pace must be at least 60 mph.
What is the average rate of change?It is a measure of how much the function changed per unit, on average, over that interval. It is derived from the slope of the straight line connecting the interval's endpoints on the function's graph.
If Allan has to make a delivery that is 1200 miles away and can only drive for 20 hours without taking a break,
we need to find his average speed to see if he can make the delivery before the 20-hour mark.
We can use the formula:
average speed = total distance / total time
We know the total distance is 1200 miles.
To find the total time, we need to know Allan's maximum driving time before taking a break. Let's assume that Allan will take a break after driving for 20 hours.
So, Allan's total time available to make the delivery is 20 hours.
Therefore,
average speed = total distance / total time
average speed = 1200 miles / 20 hours
average speed = 60 miles per hour
Allan's average speed must be at least 60 miles per hour to make the delivery before he has to take a break.

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.

The measures of the Angles of a triangle are shown in the figure below
Answer:
x = 22°
Step-by-step explanation:
The angles of a triangle add to 180°, so:
69 + (3x - 4) + (3x - 17) = 180
(3x - 4) + (3x - 17) = 111
6x - 21 = 111
6x = 132
x = 22
Answer:
22
Step-by-step explanation:
(3x - 4)° + (3x - 17)° + 69° = 180°
6x - 21 + 69 = 180
6x + 48 = 180 ⇒ x = 22

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.
