Find the area of the figure. Sides meet at right angles NO LINKS
Answer:
105 m²
Step-by-step explanation:
Dividing the figure into 3 rectangle will be easier to find its area.
The area of the larger rectangle
= (10-5) × 13
= 65 m²
The total area of the 2 smaller rectangles
= 2 × (4×5)
= 40 m²
The area of the figure
= 65 + 40
= 105 m²

Rahul, a coach at a local school has collected data on his players. But in an accident he lost how many games each player participated in. He knows that per game Michael played 30 minutes, had 1 foul, and 2 goals. Per game, Sherry played 25 minutes, had 1 foul, and 5 goals. Rashad played 20 minutes, had 2 fouls, and 4 goals per game. Rahul also knows that the total amount of all three players. Together they played 370 minutes, had 20 fouls, and 58 goals. Can you use algebra to determine how many games each athlete played in
Answer:
Michael played 4 games, Sherry played 6 games and Rashad played 5 games
Step-by-step explanation:
Let X, Y and Z represents the number of games for the three players.
Based on the given information, three equations can be formed -
30 X + 25 Y + 20 Z = 370 ---(1)
X + Y + 2Z = 20 ---(2)
2X + 5Y + 4 Z = 58 ---(3)
From Equation (2), X = 20 -Y-2Z
Substituting value of X from equation 2, in equation 1 and 2, we get -
30 (20-Y-2Z) + 25 Y + 20 Z = 370
600 -30Y-60Z + 25 Y + 20 Z = 370
-5Y -40Z = -230
Y + 8Z = 46 ----(4)
2(20-Y-2Z) + 5Y + 4 Z = 58
40 -2Y-4Z + 5Y + 4 Z = 58
3Y = 18
Y = 6
Substituting value of Y in equation 4, we get -
8Z = 46-6
8Z = 40
Z = 5
Substituting value of Y and Z in equation 2 we get
X + 6 + 2* 5 = 20
X = 20-16 = 4
Hence, Michael played 4 games, Sherry played 6 games and Rashad played 5 games

There are 16 ties on each rack.
Write an equation to find the total number of ties.
(Let t = ties and r = racks.)
Answer:
T(r) = (16 ties/racks)r
Step-by-step explanation:
Total number of ties = (16 ties/rack)(number of racks), or
T(r) = (16 ties/racks)r

DONT MINF MY PRO CROPPING. DEFF.
ALSO ITS NOT A
Answer:
I believe it's C
Step-by-step explanation:
The surface area of the bottom is 64 because it's 8 times 8.
All of the sides are 8 times 12.
8 times 12 is 96.
96 times 4 (for all four sides) is 384.
So the sides (384) plus the bottom (64) is 448, or C
Find the area of the regular polygon.
The perimeter of 14 and radius of 2.5
Answer:
The area of the regular polygon is 17.5.
Step-by-step explanation:
To find the area of the regular polygon with a perimeter of 14 and radius of 2.5, the following calculation must be performed, knowing that the area of a regular polygon arises from multiplying the perimeter by the apothem divided by two:
(14 x 2.5) / 2 = X
35/2 = X
17.5 = X
Therefore, the area of the regular polygon is 17.5.
Standardized tests for certain subjects, given to high school students, are scored on a scale of 1 to 5. Let X represent the score on a randomly selected exam. The distribution of scores for one subject’s standardized test is given in the table.
A 2-column table with 5 rows. Column 1 is labeled score with entries 1, 2, 3, 4, 5. Column 2 is labeled Probability with entries 0.18, 0.20, 0.26, 0.21, 0.15.
What is the probability of earning a score of 3 or higher?
0.26
0.36
0.62
0.66
Answer:
C. 0.62
Step-by-step explanation:
probability of earning a score of 3 or higher means the probability we are trying to find includes 3,4,5 so we just add these together to get the probability of 3 and above
3 = 0.26
4= 0.21
5= 0.15
0.26+0.21+0.15= 0.62

Answer:
Dvds cost 12 games cost 19.
Step-by-step explanation:
Put the amount of dvds and video games into an equation and assign variables.
3x+2y=74
5x+2y=98
You can solve multiple ways, although I'll do graphing for this equation.
After graphing, you get 2 lines that intersect. The point of intersection is 12,19 meaning that a dvd is 12 (x) and a video game is 19 (y)
DVD = x
video games = y
3 DVD + 2 video games = $74
3x + 2y = 74
5 DVD + 2 video games = $98
5x + 2y = 98
We can easily use eliminations by changing one of the equations, with all variables becoming negative signs, in order to eliminate the variable y.
-(3x + 2y = 74)
-3x -2y = -74
Now add both equations toegther (in order to eliminate the avriable y and solve for x).
5x + 2y = 98
-3x -2y = -74
____________
2x + 0y = 24
2x = 24
x = 12 [A DVD costs $12]
Plug that value for x into one of the equations:
5x + 2y = $98
5(12) + 2y = 98
60 + 2y = 98
2y = 38
y = 19 [A video game costs $19]
ANSWER: a DVD costs $12 and a video game costs $19choose the third option.
Pls answer this with a picture showing the correct box plot
Answer/Step-by-step explanation:
To find out the mistake of the student, let's find the min, max, median, Q1 and Q3, which make up the 5 important values that are represented in a box plot.
Given, {2, 3, 5, 6, 10, 14, 15},
Minimum value = 2
Median = middle data point = 6
Q1 = 3 (the middle value of the lower part of the data set before the median)
Q3 = 14 (middle value of the upper part of the data set after the median)
Maximum value = 15
If we examine the diagram the student created, you will observe that he plotted the median wrongly. The median, which is represented by the vertical line that divides the box, ought to be at 6 NOT 10.
See the attachment below for the correct box plot.
Otis is cutting a long piece of wood trim into smaller pieces for an art project. The line plot shows the length of the smaller pieces of wood. How many pieces of wood will be at least 1 2 foot in length?
Answer:
6
Step-by-step explanation:
From the line plot, the length of wood measuring atleast 1/2 in length include :
Piece with length 1/2 and pieces with length 2/3
Number of pieces with length 1/2 feets = 4
Number of pieces with length 2/3 feets = 2
Pieces with atleast 1/2 feet length = 4 + 2 = 6
A climber is ascending the face of a 500-foot high vertical cliff at 5 feet per minute. Her climbing partner is observing from 150 feet away. Find the function that describes the amount of time climbing as a function of the angle of elevation of the observer’s line-of-sight to the climber. Does the viewing angle ever reach 75 degrees?
Answer:
a) t (α) = 30 * tan α
b) α = 75 ° is not possible because
Step-by-step explanation:
The vertical cliff (y), the observing partner ( 150 ft ) from the point o ( the common point for the cliff and the ground ) between the cliff, and the line of sight from the observer and the climber, shape a right triangle. Hypothenuse is the distance between the partners, the cliff, and distance of the observer to the cliff are the legs.
Then
α is the elevation angle
tan α = y / 150 (1)
y(t) = elevation of the climber
y(t) = speed * time
y(t) = 5 * t
tan α = 5 *t / 150
tan α = t / 30
t (α) = 30 * tan α
b) α = 75 ° is not possible because:
tan α = y / 150 tan 75° = 3.73
Then y = 3.73 * 150 = 559 ft and the cliff is only 500 ft

Step-by-step explanation:
Dialating means you are multiplying or dividing. Since 2 is positive you multiply everything by 2, usually it would be coordinates, like if it said dialate (2,4) by 6 we would get (12, 24), but I didn't really want to have to solve the equation for the coordinates so try the answer I wrote, if not I am so so so sorry but at least now you know what dialating means.

What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that;
The options A,B,C and D
Now,
To order numbers and angles from least to greatest, you need to compare their values and arrange them in ascending order. For numbers, you can use a calculator1 or a number sorter2 to help you. For angles, you need to measure their size in degrees using a protractor3 and then classify them as acute (< 90°), right (= 90°), obtuse (> 90°) or reflex (> 180°) angles4. The smallest angle is an acute angle and the largest angle is a reflex angle.
Therefore, by algebra the answer will be л 7л < 38° < 4 < 80° < 6 < 2x
