Step-by-step explanation: To compare decimals such as 18.4 and 18.04, first line up the decimal points of the numbers.

Next, we compare the digits place by place starting on the left.

1 and 1 are the same, 8 and 8 are the same, but notice that 4 is greater than 0.

This means that 18.4 is greater than 18.04.

So to answer your question, 18.04 is less than 18.4

Answer:

250 Cookies

Step-by-step explanation:

First calculate the cookies decorated per hour

100 ÷ 2 = 50 cookies per hour

Number of cookies in 5 hours = 50 × 5

= 250 Cookies

Answer:

250

Step-by-step explanation:

Divide 100 by 2 to get the hourly rate which would be 50. Then take the hourly rate and multiply it by the number of hours given, 5. 5 multiplied by 50 equals 250 cookies

Answer:

y=sqrt(1/2x-25/2), -sqrt(1/2x-25/2).

Step-by-step explanation:

y=2x^2+25

x=2y^2+25

2y^2=x-25

y^2=1/2x-25/2

y=sqrt(1/2x-25/2), -sqrt(1/2x-25/2)

Answer:

y=2x-13

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-7-(-1))/(3-6)

m=(-7+1)/-3

m=-6/-3

m=2

y-y1=m(x-x1)

y-(-1)=2(x-6)

y+1=2x-12

y=2x-12-1

y=2x-13

Answer:

135°

Step-by-step explanation:

An angle of 45° has a supplementary angle of 180° - 45° = 135°

Answer: 135

Step-by-step explanation:

Two angles are said to be supplementary if they sum up to be 180.

Let the supplementary angle to 45 be x ,

then :

x + 45 = 180

x = 180 -45

x = 135

Answer:

1. Vertical Angles Theorem

2. Converse of Alternate Interior Angles Theorem

Step-by-step explanation:

First option:

Lines AC and BD intersect at point E. Angles AEB and CED are opposite angles formed when these two lines intersect and are called vertical angles. By vertical angles theorem, these angles are congruent. So,

Vertical Angles Theorem

Second option:

[tex]\triangle BEC\cong \triangle DEA[/tex] by SAS postulate, then

[tex]\angle CBE\cong \angle ADE[/tex] as corresponding sides of congruent triangles.

Converse of Alternate Interior Angles Theorem states that if two lines are cut by a transversal and the alternate interior angles are congruent, then the lines are parallel.

So, [tex]\overline{BC}\cong \overline{AD}[/tex] by

Answer:

1.B            2.B

Step-by-step explanation:

Answer:

y = -2x - 6

The y-intercept will be (0,-6)

One point will be at (1,-8)

The line will go downward since it is a negative slope

Step-by-step explanation:

y−2=−2(x+4)

Distribute

y - 2 = -2x - 8

Move the constant to the other side

y - 2 = -2x - 8

  +2 =        +2

y = -2x - 6

-18u+16u-7=9

-2u - 7 = 9       (combine like terms)

-2u = 16           (add 7 on both sides)

u = -8

Answer:

The correct answer to this problem is u = -8.

Step-by-step explanation:

To solve this problem, we first must combine like terms on the left side of the equation.  This means adding together the two terms that have a "u" multiplied by a number.  To combine them, we simply add the coefficients together, as we would with constant values.  This is modeled below:

-18u+16u-7=9

-2u - 7 = 9

Next, we want to add 7 to both sides of the equation.  This will cancel out the -7 on the left side of the equation, isolating the term with the variable u (what we are trying to solve for).

-2u - 7 + 7 = 9 + 7

-2u = 16

Finally, we want to divide both sides by -2 in order to isolate the variable u.  This will get rid of the coefficient of negative 2 and give us our answer.

u = 16/-2 = -8

Therefore, the answer to this question is u = -8.

Hope this helps!

Answer:

[tex]\large \boxed{\text{A. }\dfrac{13}{7}\text{; B. }\dfrac{17}{14} \text{; C. 507 in}^{2}}[/tex]

Step-by-step explanation:

A. Scale factor

When you dilate an object by a scale factor, you multiply its line lengths by the same number.

If EF/AB = 13/7, the scale factor is 13/7.

B. Length of EF

[tex]\begin{array}{rcl}\dfrac{EF}{AB} & = & \dfrac{13}{7}\\\\\dfrac{EF}{\frac{17}{26}} & = & \dfrac{13}{7}\\\\EF & = & \dfrac{13}{7}\times\dfrac{17}{26}\\\\ & = &\dfrac{1}{7}\times\dfrac{17}{2}\\\\ & = & \mathbf{\dfrac{17}{14}}\\\end{array}\\\text{The length of EF is $\large \boxed{\mathbf{ \dfrac{17}{14}}}$}[/tex]

C. Area of EFGH

If the lengths in a shape are all multiplied by a scale factor, then the areas will be multiplied by the scale factor squared.

ABCD is dilated by a scale factor of 13/7, so its area is dilated by a scale factor of

[tex]\left(\dfrac{13}{7} \right)^{2} = \dfrac{169}{49}[/tex]

The area of its dilated image EFGH is

[tex]\text{Area of EFGH} = \text{147 in}^{2} \times \dfrac{\text{169}}{\text{49}} = 3 \times 169\text{ in}^{2} = 507 \text{ in}^{2}\\\\\text{The area of EFGH is $\large \boxed{\textbf{507 in}^{\mathbf{2}}}$}[/tex]

Answer: [tex]\frac{1}{64}[/tex]

[tex](2N)(25)=\frac{25}{32}[/tex]

Answer:

s = P - t - r

Step-by-step explanation:

You are solving for the variable, s. To do so, isolate the variable. Note the equal sign, what you do to one side, you do to the other.

First, subtract the variable t from both sides of the equation:

P (- t) = s + t (-t) + r

P - t = s + r

Next, isolate the variable s by subtracting r from both sides:

P - t (-r) = s + r (-r)

P - t - r = s

s = P - t - r

s = P - t - r is your answer.

Whitney's speed was 35 miles per hour.

Let's let x represent Whitney's speed in miles per hour (mi/h). Then, Whitney's mother's speed would be x + 5 mi/h. Since time is equal to distance divided by speed, and both Whitney and her mother arrived at the same time, we can set their times equal to each other:

Whitney's time = Distance / Speed = 7 miles / x mi/h

Mother's time = Distance / Speed = 8 miles / (x + 5) mi/h

7/x = 8/(x + 5)

7(x + 5) = 8x

7x + 35 = 8x

x = 35 mi/h

Therefore, Whitney's speed was 35 miles per hour.

Answer:

4:24 p.m.

Step-by-step explanation:

Figure out how often the buses leave at the same time. This is the same as the least common multiple (LCM) of how often they leave the stadium.

The LCM is found by multiplying the maximum number of each prime factor found in any of the numbers.

The prime factors of a number are found by dividing it by whole numbers until the factors are all prime. Prime numbers only have the factors 1 and itself.

6 = 2 X 3

8 = 2 X 2 X 2

The greatest times 2 repeats is three times.

The greatest times 3 repeats is one time.

2 X 2 X 2 X 3 = 24

The LCM is 24, and the buses have the same leaving times every 24 minutes.

Find 24 minutes after 4:00 p.m. Change the minutes only, which are the numbers right of the colon : .

The buses will next leave together at 4:24 p.m.

Answer:

Part 1) The perimeter of rectangle is equal to 24 units

Part 2) The area of rectangle is equal to 32 square units

Step-by-step explanation:

Part 1) Find the perimeter of rectangle

we know that

The perimeter of rectangle is equal to

[tex]P=2(L+W)[/tex]

where

L is the length of rectangle

W is the width of rectangle

we have

[tex]F(-2,5),R(-2,1),O(6,1),G(6,5)[/tex]

Plot the figure to better understand the problem

using a graphing tool

see the attached figure

Remember that in a rectangle opposite sides are congruent and the measure of each interior angle is equal to 90 degrees

so

[tex]FG=RO=L\\RF=OG=W[/tex]

the formula to calculate the distance between two points is equal to

[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]

step 1

Find the distance FG

[tex]F(-2,5),G(6,5)[/tex]

substitute the values

[tex]d=\sqrt{(5-5)^{2}+(6+2)^{2}}[/tex]

[tex]d=\sqrt{(0)^{2}+(8)^{2}}[/tex]

[tex]FG=8\ units[/tex]

step 2

Find the distance RF

[tex]R(-2,1),F(-2,5)[/tex]

substitute the values

[tex]d=\sqrt{(5-1)^{2}+(-2+2)^{2}}[/tex]

[tex]d=\sqrt{(4)^{2}+(0)^{2}}[/tex]

[tex]RF=4\ units[/tex]

step 3

Find the perimeter

[tex]P=2(L+W)[/tex]

we have

[tex]FG=RO=L=8\ units\\RF=OG=W=4\ units[/tex]

substitute

[tex]P=2(8+4)=24\ units[/tex]

Part 2) Find the area of rectangle FROG

we know that

The area of rectangle is equal to

[tex]A=LW[/tex]

we have

[tex]FG=RO=L=8\ units\\RF=OG=W=4\ units[/tex]

substitute

[tex]A=(8)(4)=32\ units^2[/tex]

The area and the perimeter of the rectangle FROG is evaluated as:

For a rectangle with length and width L and W units, we get:

The shortest distance(straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

[tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]

The coordinates of the points of the rectangle FROG are given as:

F(-2,5), R(-2,1), G(6,5), and O(6,1) (from its plot, as given below)

FR and RO are length and width pair(we can call any one of them as length and other as width) of the considered rectangle as they are adjacent to each other.

We denote length of a line segment AB by |AB|

Thus, we get:

Now with the help of length and width, we can evaluate its perimeter and area, as shown below:
