Answer:
18+10.3
Step-by-step explanation:
The expression doesn't have to include a variable, so you can pick two random numbers that add up to 28.3. In this case, I used 18 and 10.3. Simple.
Find the diagonal length of a rectangular TV screen with the a length of 25 inches and a width of 28 inches.
Answer:
37.5 inches
Step-by-step explanation:
Applying the Pythagorean Theorem,
a²+b²=c²
where c is the diagonal length
c=√(25²+28²)= 37.5
In the seating for a concert, the first row has 10 chairs. Every row after that has 2 more chairs. 7. What is the explicit formula that models this situation? 8. How many chairs are in row 20?
9514 1404 393
Answer:
7. c(n) = 10 +2(n -1)
8. c(20) = 48
Step-by-step explanation:
7. Your arithmetic sequence has first term a1=10 and constant difference d=2. The explicit formula for terms of an arithmetic sequence is ...
an = a1 +d(n -1)
If we use c(n) as the function name for the function giving the number of chairs in row n, then we can fill in the numbers we know to get ...
c(n) = 10 + 2(n -1)
__
8. Evaluating the function when n=20, we find ...
c(20) = 10 +2(10-1) = 10 +2·19 = 10 +38
c(20) = 48
There are 48 chairs in row 20.

If f(x)=x-3, which inequality can be used to find the domain of f(x)?
Ovx-3>0
O x-3>0
O vx-3 <0
O x-3<0
Given that,
[tex]f(x) = \sqrt{x-3}[/tex]
To find,
The domain of f(x).
Solution,
We have, [tex]f(x) = \sqrt{x-3}[/tex]
To find domain,
The term under the square root must be positive or null as follows :
[tex]x-3\ge 0[/tex]
Adding 3 both sides
[tex]x-3+3\ge 0+3\\\\x\ge 3[/tex]
So, the domain is x-3>0 .

Point T T is located at ( − 1 , − 4 ) (−1,−4) on the coordinate plane. Point T T is reflected over the x x-axis to create point T ′ T ′ . Point T ′ T ′ is then reflected over the y y-axis to create point T ′ ′ T ′′ . What ordered pair describes the location of T ′ ′ ? T ′′ ?
Given:
The point is located at (-1,-4).
Point T is reflected over the x-axis to create point T′.
Point T′ is then reflected over the y-axis to create point T′′.
To find:
The ordered pair describes the location of T''.
Solution:
We have, the given point T(-1,-4).
Point T is reflected over the x-axis to create point T′. So, the rule of reflection is
[tex](x,y)\to (x,-y)[/tex]
[tex]T(-1,-4)\to T'(-1,4)[/tex]
Point T′ is then reflected over the y-axis to create point T′′. So, the rule of reflection is
[tex](x,y)\to (-x,y)[/tex]
[tex]T'(-1,4)\to T''(1,4)[/tex]
Therefore, the ordered pair (1,4) escribes the location of T′′.

Evaluate when f(-3) and f(7)
f(x) = {3x-1,tfx>4
{2x,tfx<4
_
Answers:
f(-3) = -6f(7) = 20======================================================
Explanation:
The piecewise function f(x) changes based on what the input is.
We have two cases:
Case A) if x > 4, then f(x) = 3x-1Case B) If [tex]x \le 4[/tex], then f(x) = 2xThe input x = -3 satisfies the inequality [tex]x \le 4[/tex], so we go with case B for this input
f(x) = 2x
f(-3) = 2(-3)
f(-3) = -6
In contrast, the input x = 7 satisfies the inequality x > 4. So we go for case A this time.
f(x) = 3x-1
f(7) = 3(7)-1
f(7) = 21-1
f(7) = 20
----------------------
Side note: It might be better to let g(x) = 3x-1 and h(x) = 2x. Then we could further say "If x > 4, then f(x) = g(x) OR if [tex]x \le 4[/tex], then f(x) = h(x)". Though this might be a more wordy definition.
The sum of the measures of two adjacent angles is 72 degrees. The ratio of the smaller angle to the
larger angle is 1:3. Find the measure of the larger angle.
Answer:
The larger angle is 54°
Step-by-step explanation:
Given
Let the angles be: θ and α where
θ > α
Sum = 72
α : θ = 1 : 3
Required
Determine the larger angle
First, we get the proportion of the larger angle (from the ratio)
The sum of the ratio is 1 + 3 = 4
So, the proportion of the larger angle is ¾.
Its value is then calculated as:.
θ = Proportion * Sum
θ = ¾ * 72°
θ = 3 * 18°
θ = 54°

Which of the following is not represented in the image below?
4.
Line segment BC
Ray CA
Point
Ray DB
Answer:
Ray CA
Step-by-step explanation:
There is a point in-between.
A ray cannot depict CA because it extends from both of its ends.
Option 2 is correct.
What is a Ray?In mathematics, a ray is a segment of a line with a fixed starting point but no ending. That can go on forever in a single direction. A ray cannot be measured since it has no end point.
Point: Point is a dot or vertex of any figure or diagram. It represents by capital alphabet. So, B would be a point.
Line: A line is a straight path with both endless. It means we can extends line from both end. But in case of BD we can't extend from point B. So, it won't be a line.
Ray: A ray is a straight path with one endless. It means we can't extend line from one end and extend from another end. But we can extend AC from both end. It won't be a ray.
Line Segment: A line segment is a straight path with end from both end. We can't extend from either end of the line. We can say CD would be line segment.
CA cannot be represented by a ray, as it's extending from both of its ends.

Percents
Michael is leaving a 15% tip for his waitress. What percent of the
original price will he pay? Write your answer as a percent, decimal,
and fraction.
Answer:
Percentage: 115%
Decimal: 1.15
Fraction: [tex]\frac{23}{20}\\[/tex]
Step-by-step explanation:
Percentages, Fractions, and Decimals
Assume we set 100% as the original price of the food that Michael consumed. When he leaves a 15% tip for the waitress, he is really paying 100%+15%=115% of the original price.
Now we express 115% as a decimal, simply dividing by 100:
115% = 115/100 = 1.15
To express it as a fraction, we simplify the division instead of calculating it:
115% = [tex]\frac{115}{100}[/tex]
Simplifying by 5:
115% = [tex]\frac{23}{20}[/tex]

What are the coordinates of the point on the directed line segment from
(-4,-9) to (1, 1) that partitions the segment into a ratio of 3 to 2?
Answer:
(- 1, - 3 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) partitioned in the ratio m : n
Then using the Section formula the coordinates of the point are
( [tex]\frac{nx_{1}+mx_{2} }{m+n}[/tex], [tex]\frac{ny_{1}+my_{2} }{m+n}[/tex] )
Here (x₁, y₁ ) = (- 4, - 9), (x₂, y₂ ) = (1, 1) and m : n = 3 : 2 , then
( [tex]\frac{2(-4)+3(1)}{3+2}[/tex] , [tex]\frac{2(-9)+3(1)}{3+2}[/tex] )
= ( [tex]\frac{x}{y} \frac{-8+3}{5}[/tex], [tex]\frac{-18+3}{5}[/tex] )
= ( [tex]\frac{-5}{5}[/tex], [tex]\frac{-15}{5}[/tex] )

find the slope of the given points (3,4) and (7,-4)
Answer:
m = -2Step-by-step explanation:
[tex]\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
(3, 4) ⇒ x₁ = 3, y₁ = 4
(7, -4) ⇒ x₂ = 7, y₂ = -4
So the slope:
[tex]\bold{m=\dfrac{-4-4}{7-3}=\dfrac{-8}4=-2}[/tex]
2 is the slope of the passing through points (3,4) and (7,-4).
What is Slope?The slope of a line is a number that describes both the direction and the steepness of the line.
Given that a line is passing through the points (3,4) and (7,-4).
Slope = ([tex]y_{2}[/tex] - [tex]y_{1}[/tex])/([tex]x_{2}[/tex] - [tex]x_{1}[/tex])
Therefore, slope = (-4-4)/(7-3) =-8/-4 = 2
Hence, 2 is the slope of the passing through points (3,4) and (7,-4).

"Leo and Stan start to ride their bikes at the same time from the same point on a
circular track. If it takes Leo 36 seconds to complete on revolution around the
track and it takes Stan 40 seconds to make one revolution around the track, how
many minutes will it take for them to meet again at the starting point?
I need help?
Answer:
6 minutes
Step-by-step explanation:
Given
Leo = 36 sec / rev
Stan = 40 sec/rev
Required
Determine the time (in minutes) they'll meet again
We start by getting the multiples of 36 and 40 uptil we get a common multiple.
Leo: 36 = 36, 72, 108, 144, 180, 216, 252, 288, 324, 360, .....
Stan: 40 = 40, 80, 120, 160, 200, 240, 280, 320, 360....
From above, the common multiple is:
Common Multiple = 360
This means that they'll meet at 360 seconds
Convert to minutes
360 sec = 360/60 mins
360 Seca = 6 mins
Hence,it will take them 6 minutes to meet again at the starting point

PLEASEE HELP THANK YOU!!!
Answer:
D. 3-5
Step-by-step explanation:
Absolute Value
[tex] |a| = a \\ | - a| = a[/tex]
Given where a-term is greater or equal to 0.
Example
[tex] |1| = 1 \\ | - 1| = 1 \\ | - 20| = 20[/tex]
Back to the question, we evaluate the absolute value of 3-5.
[tex] |3 - 5| \\ | - 2| [/tex]
Any negative real numbers in absolute will become positive real numbers.
Therefore, our answer is —
[tex]2[/tex]
Consider all choices.
[tex] |5 - 3| = |2| = 2 \\ |3 - 5| = | - 2| = 2 \\ 5 - 3 = 2 \\ 3 - 5 = - 2[/tex]
The only answer that is different is the last choice, 3-5 = -2
