what is the simplified form of the fraction 7/28
Answers
Answer:
1/4
Step-by-step explanation:
7 divided by 24 = 4 so it gets reduced to 1 and then 1/4
The solution is: 1/4 is the simplified form of the fraction 7/28.
Here, we have,
given that,
the fraction is: 7/28
now, we divide each fraction numerator and denominator by a common divisor of them,
here, we know that,
7 * 1 = 7
7*4 = 28
so, the gcf of 7 and 28 = 7
we divide each fraction numerator and denominator by a common divisor 7,
we will get:
7/28 = 1/4
7 divided by 28 = 4 so it gets reduced to 1 and then 1/4.
Hence, The solution is: 1/4 is the simplified form of the fraction 7/28.

A balalaika is a Russian stringed instrument. Show that the triangular parts of the two balalaikas are congruent for x = 6.
Answers
*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.
can someone please help me with a proof for this. you can use HL thereom, ASA, SSS, etc.

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.
Answers
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.

We can represent this with an inequality symbol.
We will use H to represent the height of the visitor.
H ≥ 50
All this means is that height of visitors must be equal to or more than 50.

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?
Answers
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

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?
Answers
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.

Answers
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

Answer is 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 .
