Answer:

1 [tex]\frac{11}{25}[/tex]

Step-by-step explanation:

You want to write out the fraction from the division problem.

To do this you want to know that the number that is being DIVIDED BY (or 36 in this problem) is the numerator (the number on top in the fraction) and the number DIVIDING the number that is being divided by is the denominator (or 25 in this problem).

You can then write this as the fraction [tex]\frac{36}{25}[/tex] . Next you want to change this into a mixed number to simplify the fraction. To simplify you want to do 36-25 because 36 exceeds 25. 36-25=11. Because you have 11 remaining you would keep it with the 25th fraction. The completed fraction should look like this 1 [tex]\frac{11}{25}[/tex] .

Answer:

A) A 90 degree counterclockwise rotation about the origin followed by a translation 1 unit to the left

Step-by-step explanation:

The formula to do a 90 degree counterclockwise rotation is (x, y) to (y, -x) so if the ordered pair is (5, 3) and you were to rotate it counterclockwise it would be (3, -5). Once you do this to all of the values, you are one unit to the right of what you should be, so then you would have to translate it 1 to the left in order to match up both of the trapezoids.

Answer:

20

Step-by-step explanation:

Multiply 50 by 0.4

Side length = 16.7 cm

Solution:

Perimeter of a square given = 66.8 cm

In a square four sides are equal.

The perimeter of a square = 4 × side

⇒ 4 × side = 66.8 cm

Divide both sides of the equation by 4 to equal the expression.

⇒ side = 66.8 ÷ 4

⇒ side = [tex]\frac{66.8}{4}[/tex]

⇒ side = 16.7 cm

Hence, the side length of the square is 16.7 cm.

Explanation:

Find -9/4 = -2 1/4 on the number line. Put an open circle at that point.

Shade the number line to the left of there, representing all values less than -9/4. The dot at -9/4 is open because it is not included in the graph.

The endpoints C and D has no midpoint M.

Step-by-step explanation:

step 1: The given endpoints of C and D are (-4,10) and (-4,10)

step 2: Midpoint formula = ((x1+x2)/2 , (y1+y2)/2)

step 3: Here, C(-4,10) = (x1,y1)

                      D(-4,10) = (x2,y2)

step 4: The midpoint represents the half distance of the line CD. Since C and D are same points, they cannot form a line. Therefore, the endpoints CD have no midpoint.

Answer:

Step-by-step explanation:

Given that (x + 8) is a factor of f(x), then x = - 8 is a root and thus

f(- 8) = 0

If (x+8) is a factor of f(x) then f(-8) =0 is the true statement.

" Factor is defined as an algebraic expression or a number when divided by another algebraic expression or a number without leaving remainder."

According to the question,

Given function = f(x)

Factor of f(x) = (x+ 8)

For example  [tex]f(x) = x^{2} + 12x+32[/tex]

                              [tex]= x^{2}+8x+4x+32 \\\\= (x+8) (x+4)[/tex]

(x+ 8) is a factor of f(x).

[tex]f(-8) = (-8)^{2} -64[/tex]

         [tex]= 64-64\\\\=0[/tex]

Hence, if (x+8) is a factor of f(x) then f(-8) =0 is the true statement.

Answer:

P=30

Step-by-step explanation:

width = x

length = 2x

2x^2=50

/2       /2

x^2=50

[tex]\sqrt{x^{2} }[/tex] = [tex]\sqrt{25}[/tex]

x=5

width=5

length=10

2width + 2length = Perimeter

10+20=P

30=P

Final answer:

The width of the rectangle is determined to be 5 feet using the area formula, leading to a length of 10 feet. The perimeter is then calculated using the sum of twice the length and twice the width, resulting in a perimeter of 30 feet.

Explanation:

To solve for the perimeter of a rectangle where the area is 50 square feet and the length is twice the width, we first use the given information to set up an equation. Let the width be w feet. Therefore, the length will be 2w feet. The area A of a rectangle is given by the formula A = length times width, so in this case, A = 2w times w = 50.

Solving for w, we have w² = 25, which gives us w = 5 feet. The length, therefore, is 2 times 5 = 10 feet. The perimeter P of a rectangle is given by P = 2 times (length + width), so the perimeter of this rectangle is P = 2 times (10 + 5) = 30 feet.

To simplify the expression 8.4(7x-4)+3.9, distribute 8.4 to both terms inside the parentheses and then add 3.9, resulting in 58.8x - 29.7.

The problem 8.4(7x-4)+3.9 requires simplification by applying the distributive property and then combining like terms. First, multiply 8.4 by both 7x and -4, and then add the constant 3.9 to the result.

Answer:

30 out of 50 times.

Step-by-step explanation:

1 attempt represents 3 out of 5 times.

10 attempts equals 1 attempt x 10.

Multiply numbers 3 and 5 by 10.

3 x 10 = 30

5 x 10 = 50.

Therefore, your solution is 30 / 50 times.

Using the probability of the initial success rate (60%), if you attempt to swim across the pool without taking a breath 10 times, you are expected to succeed 6 out of 10 times.

The question you're asking involves a simple concept in mathematics known as probability. The event of you being able to swim across the pool without taking a breath has so far occurred with a probability of 3 successes out of 5 attempts, or a 60% success rate. This is essentially an application of a ratio - you have succeeded 3 times for every 5 attempts you made. We can apply this ratio to predict outcomes over a larger number of trials.

If you were to attempt to swim across the pool without taking a breath 10 times and maintain the same success rate of 60%, you would be expected to make it 6 times out of 10 (since 60% of 10 is 6). Here's the breakdown:

Calculate the success rate from the initial trials: 3/5 = 60%

Apply that success rate to a larger number of trials: 60% of 10 = 6

Note that real-life scenarios might deviate slightly due to variability, but based on the given probability, we predict 6 successful swims across the pool in 10 attempts.1

Answer:

Nearest hundred: 0

Nearest hundredth: 26.35

Step-by-step explanation:

The hundred place value is three numbers to the left of the dot.

The two hundreds that are nearest to 26.35 are 0 and 100. To decide if you should round up (to 100) or round down (to 0), use the place value that is to the right of the hundred place: the number you are using is 2.

The rule for rounding:

Round up if the place value is 5 or more

Round down if the place value is 4 or less

Since 2 is "4 or less", round down to 0.

Since 26.35 is closer to 0 than 100:

26.35 => 0 when rounded to the nearest hundred

In case you meant hundredth:

The nearest hundredth means two decimal places, or two numbers right of the dot.

The number 26.35 already has two decimal places, so rounded to the nearest hundredth is still 26.35.

26.35 => 26.35

p = 7 + 0.46x is the monthly cost for x text messages

Solution:

Given that, A text message plan costs $7 per month plus $0.46 per text

To find: Monthly cost for "x" text messages'

Let "x" be the number of text messages in a month

From given information,

text message plan cost per month = $ 7

Cost for 1 text = $ 0.46

Let "p" be the Monthly cost for "x" text messages

Then, we get,

p = text message plan cost per month + (Cost for 1 text)(number of text messages in a month)

[tex]p = 7 + 0.46x[/tex]

Thus the monthly cost for x text messages is found
