Answers

Answer 1
8 and 8


Hope this helps!!!!

:):):)
Answer 2

Answer:

8 x ( 7 + 3 ) = (8 x 7) + ( 8 x 3)

OR (if you want to solve)

80

Step-by-step explanation:

This equation represents the distributive property.

When there is a number on the outside of parentheses we can multiply it by every number within the parentheses.

So when we solve this, it can look like this:

8 x (7 + 3)

(8 x 7) + (8 x 3)

(56) + (24)

= 80

I hope this helps!!

The blue portion of the American flag is known as the union. Using the measurements in the diagram, determine if the rectangle enclosing the union is similar to the rectangle enclosing the entire flag.

Answers

They are not similar.

The dimensions of the Union are 3'x5'.

The dimensions of the overall flag are 9-1/2'x5'.

Hope this helps ^^

The rectangle enclosing the union is not similar to the rectangle enclosing the entire flag.

Given that the flag's union portion has dimensions = 18.24 in and 13 in, whereas the entire flag has the dimension = 3.8 ft and 2 ft,

We need to check if the rectangle enclosing the union is similar to the rectangle enclosing the entire flag.

To determine if the rectangle enclosing the union portion of the flag is similar to the rectangle enclosing the entire flag, we can compare their aspect ratios.

The aspect ratio of a rectangle is calculated by dividing its longer side by its shorter side.

In this case, for the union portion of the flag, the longer side is 18.24 inches, and the shorter side is 13 inches.

Thus, the aspect ratio of the union rectangle is:

Aspect ratio of union rectangle = 18.24 in / 13 in ≈ 1.403

For the entire flag, the longer side is 3.8 feet (which is equivalent to 45.6 inches) and the shorter side is 2 feet (which is equivalent to 24 inches). Therefore, the aspect ratio of the rectangle enclosing the entire flag is:

Aspect ratio of entire flag rectangle = 45.6 in / 24 in ≈ 1.9

Since the aspect ratios of the two rectangles are different (1.403 vs. 1.9), we can conclude that the rectangle enclosing the union portion of the flag is not similar to the rectangle enclosing the entire flag.

Which expression is equivalent to 12a⁻⁴ b³c⁸/3a⁻² b⁹c⁻²
for all values of a, b, and c where the expression is defined?

Answers

To simplify the expression, we can use the laws of exponents:

12a⁻⁴ b³c⁸ / 3a⁻² b⁹c⁻²

= (12/3) (a⁻⁴ / a⁻²) (b³ / b⁹) (c⁸ / c⁻²)

= 4 (a⁻⁴+2) (b³-9) (c⁸+2)

= 4a⁻² b⁻⁶ c¹⁰

Therefore, the expression is equivalent to 4a⁻² b⁻⁶ c¹⁰ for all values of a, b, and c where the expression is defined.

Yes, they are. Congruence are two objects, doesnt matter if its two dimensional or three dimensional. They are all identical in size and shape. In geometry, congruent figures have three properties: 1. The same size. 2. Same shape. 3. Parts that are corresponding are congruent. One example are ches peices, A knight is on a high shelf, the other a low shelf, Just because they are in different planes of three dimensions does NOT mean it rules out their congruence.

2x+y=11
1/2x-5y=8

please help!!!

Answers

Answer: ( x,y ) = ( 96/43, 152/43 )

Step-by-step explanation:

Answer: ( x,y ) = ( 96/43, 152/43 )

Step-by-step explanation:

rewrite the expression

2x + y=8

11 1/2 x X - 5y=8

mixed fraction btw.

simplify

2x + y =8

23x - 10y = 16

multiply both sides

20x + 10y = 80

23x - 10y = 16

eliminate one variable by adding the equations

43x =96

divide both sides

x = 96/43

substitute the value of x

2 x 96/43 + y = 8

solve the equation

y = 152/43

a possible solution is

( x,y ) = ( 96/43, 152/43 )

check solution

simplify

8 = 8 = 8

the ordered paired is a solution!

final answer: ( x,y ) = ( 96/43, 152/43 )

rewrite the first equation as y = -2x+11
plug in this equation into the second equation
solve for x
x=6

plug x=6 into the first equation
solve for y

Dalvin's family took a road trip to Mount Rushmore. Dalvin fell asleep 44% of the way through the trip. If Dalvin fell asleep after they had travelled 176 miles, what was the total length of the trip?

Answers

Answer:

The total length of the trip was 400 miles.

Step-by-step explanation:

He fell asleep at 44% through the trip, they already had traveled 176 miles.

.44x = 176 ⇒

176 ÷ .44 ⇒

x = 400

The total length of the trip was 277 miles when Dalvin fell asleep after they had traveled 176 miles.

What is the distance?

A mathematical number known as distance measures "how much ground an object has traveled" while moving. Distance is defined as the product of speed and time.

If Dalvin fell asleep 44% of the way through the trip, then the total length of the trip is 100% - 44% = 56% longer than the distance Dalvin's family had traveled when he fell asleep.

The total length of the trip is therefore 1.56 times the distance that Dalvin's family had traveled when he fell asleep.

Since Dalvin's family had traveled 176 miles when he fell asleep, the total length of the trip is 1.56 x 176 miles = 277 miles.

Therefore, the total length of the trip was 277 miles.

the area of the parallelogram shown is 9 square inches set up and solve an equation to find the value of

Answers

ANSWER: X = 45
First, you have to set up the equation.
If the area of the square is 9, and one side is 3 square units, then the other side must also be 3 units because 3X3=9.
When finding the value of a variable, you ALWAYS want to get the variable alone on one side.
So now, you take the equation, 1/9x-2 and make is equivalent to 3.
1/9x-2=3
Now, to simplify, you add to to undo the -2, and add 2 to the 3
1/9x-2(+2)=3+2
So now the equation is 1/9x=5
To undo a fraction, think of it as a division problem. To undo a division problem, you must multiply the fraction by the denominator.
1/9x(9)=5(9)
5X9 is 45
So the answer is X=45
And is you want to check it:
1/9(45)-2=3
1/9X45 is 45/9 or 5
5-2=3
3=3
The answer is X=45

If the area of the parallelogram shown is 9 square inches. The value of x will be 45.

What is parallelogram?

In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°. Similar to how the area of a rectangle is calculated, the formula for calculating the area of a parallelogram is base times height.

It is given that the sides of the parallelogram are (1/9x-2) and 3 and the area is 9 square inches.

The area of the parallelogram will be the product of their sides as,

Area = Side A × Side B

A =  (1/9x-2) 3

9 = 1/3x-6

Simplify the equation to find the value of x,

9+6 = 1/3x

15=1/3x

x=45

Thus, if the area of the parallelogram shown is 9 square inches. The value of x will be 45.
