In English language, a sentence is a group of words or phrases that comprises a subject and predicate, which are typically used by an author or speaker in order to convey a logical information about a subject matter to an audience (readers or listeners).
A verb is one of the parts of speech in English language and it refers to any word that describes an action, occurrence, or a state of existence.
In this context, we can reasonably infer and logically deduce that the most appropriate word to complete the sentence is "are" because it is a linking verb and it connects the subject with objects in plural form.
what is the supplementary angle of 45 percent
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

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.

Whitney left school and drove 7 miles to meet her mother at a restaurant. Her mother left at the same time and drove 8 miles, traveling 5 mi/h faster than her daughter. If the two arrived at the restaurant at the same time, what was Whitney’s speed?
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.

P=s+t+r for s simplfy your answer
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.

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:
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:
Area(FROG) = [tex]32 \: \rm unit^2[/tex]Perimeter(FROG) = [tex]64\: \rm units[/tex]How to find the area and the perimeter of a rectangle?For a rectangle with length and width L and W units, we get:
Area of the rectangle = [tex]L \times W \: \rm unit^2[/tex]Perimeter of the rectangle = [tex]2(L + W) \: \rm unit^2[/tex]What is the distance between two points ( p,q) and (x,y)?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:
Length of the rectangle = |FR| = [tex]\sqrt{(-2-(-2))^2 + (1 - 5)^2 } = 4[/tex] unitsWidth of the rectangle = |RO| = [tex]\sqrt{(6-(-2))^2 + (1 - 1)^2 } = \sqrt{64} = 8 \: \rm units[/tex]Now with the help of length and width, we can evaluate its perimeter and area, as shown below:
Area(FROG) = [tex]L\times W = 4 \times 8= 32 \: \rm unit^2[/tex]Perimeter(FROG) = [tex]2(L + W) = 2(4 + 8) = 64\: \rm units[/tex]Learn more about distance between two points here:

What is the volume of this rectangular prism 7/5 CM by 5 cm and 7/2 cm
Answer:
[tex]V=\frac{49}{2}\ cm^3[/tex]
or
[tex]V=24.5\ cm^3[/tex]
Step-by-step explanation:
we know that
The volume of the rectangular prism is
[tex]V=LWH[/tex]
where
L is the length
W is the width
H is the height
substitute the given values in the formula
[tex]V=(\frac{7}{5})(5)(\frac{7}{2})[/tex]
[tex]V=\frac{245}{10}\ cm^3[/tex]
Simplify
[tex]V=\frac{49}{2}\ cm^3[/tex] ---> fraction form
or
[tex]V=24.5\ cm^3[/tex] ----> decimal form
The volume of the rectangular prism is 24.5 cm³.
To find the volume of a rectangular prism, you use the formula Volume = length × width × height. Given the dimensions of the prism are 7/5 cm by 5 cm and 7/2 cm, we calculate the volume by multiplying these three dimensions together.
Volume = (7/5) cm × 5 cm × (7/2) cm
First, simplify the calculation by multiplying the whole numbers: Volume = (7 × 5 × 7) / (5 × 2) cm³, which simplifies to Volume = 49/2 cm³. Then, divide 49 by 2 to get Volume = 24.5 cm³.
