Answer:
295 square feet
Step-by-step explanation:
Break the figure up into 3 rectangles, and then find the area of each rectangle and add all areas together.
15*3=45
19*10=190
15*4=60
45+190+60=295
Answer:26 *15*4*5*3=23400
Step-by-step explanation: Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.

An engineer traveled 150 mi by car and then an additional 630 mi by plane. The rate of the plane was three times the rate of the car. The total trip took 8 h. Find the rate of the car.
Answer:
Step-by-step explanation:
150 mile by car x mph
630 mile by plane 3x mph
Total travel time equal 8 hours
150 / x mile / (mile / hour) = hour
630 / 3x mile / (mile / hour) = hour
150/x + 630/3x = 8 hours
450/3x + 630/3x = 8 hours
450 + 630 = 8(3x) = 24x
1080 = 24x
45 = x the rate of the car is 45 mph

How is the graph of the parent function y= hurrrr!!!x2 transformed to produce the graph of y= 3(x+1)2? It is translated 1 unit right and compressed vertically by a factor of 3. © It is translated 1 unit left and compressed vertically by a factor of 3. Olt is translated 1 unit right and stretched vertically by a factor of 3. It is translated 1 unit left and stretched vertically by a factor of 3.
Answer:
3.
Step-by-step explanation:
The graph is being moved to the left and then stretched by a factor of three. If it were to be compressed than the 3 would be 1/3.
The graph of the parent function is translated to 1 unit left and compressed vertically by a factor of 3.
Option B is the correct answer.
What is translation?It is the movement of the shape in left, right, up, and down direction.
The translated shape will have the same shape and shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
The graph of the parent function y = x² can be transformed to produce the graph of y = 3(x + 1)² by translating it 1 unit to the left and stretching it vertically by a factor of 3.
Here's why:
The (x + 1) part inside the square means that the graph is shifted 1 unit to the left.
The exponent of 2 means that the graph is squared, just like the parent function.
The coefficient of 3 in front of the square means that the graph is stretched vertically by a factor of 3.
Therefore,
It is translated 1 unit left and compressed vertically by a factor of 3.

the perimeter of a rectangle is 240 ft., If the length is 12 ft., then what is the width
Answer:
w=108
Step-by-step explanation:
Using the formula
P=2(l+w)
Solving for w
w=P /2﹣l = 240 /2﹣12 = 108
Answer:
width=20
Step-by-step explanation:
the area of a rectangle= length times width
12x=240
then you divide 12 by both sides, so the answer is 20

At 1am the temperature was -6°C. At 5am it was -1°C. If the temperature
continues to rise steadily, what will the temperature be at 9am?
Answer:
4 temp at 9 am
Step-by-step explanation:
At 1am temp=-6
At 5am temp=-1
5-1=4 hours and temp difference is -6+1=-5

From an observation point A, a forest ranger sights a fire at a bearing of 215°50'. From a point b, 8 miles due west of A another ranger sights the fire at a bearing of 125°50'. Approximate to the nearest tenth of a mile, the distance of the fire from A.
Answer:
Step-by-steYou have two angles,
A=32°20'
B=57°40'
so, angle F at the fire, is 90°
d/5 = cosA = .845
d = 4.2 mi
If angle F had not been 90°, then using the law of sines,
d/sinA = 5/sinF

If the perimeter of the rectangle is 56 cm, find its length and width.
cm
Х
length: 0
width: Ich
?
cm
Answer:
I. L = 17 cm.
II. W = 11 cm.
Step-by-step explanation:
Let the length of the rectangle be L.
Let the width of the rectangle be W.
Given the following data;
Perimeter of rectangle = 56cm
Translating the word problem into an algebraic expression, we have;
L = W + 6 .....equation 1
The perimeter of a rectangle is given by the formula;
P = 2(L + W)
56 = 2(L + W) ......equation 2
Substituting eqn 1 into eqn 2, we have;
56 = 2(W + 6 + W)
56 = 2(6 + 2W)
Opening the bracket, we have;
56 = 12 + 4W
4W = 56 - 12
4W = 44
W = 44/4
W = 11 cm
Next, we would find the length of the rectangle;
From eqn 1;
L = W + 6
L = 11 + 6
L = 17 cm

Does the set of points represent a function? Explain.
Answer:
NO
Step-by-step explanation:
Recall: for a relation or a set of points to be a function, every x-value or input must have exactly one y-value or output.
From the given set of points, the x-value (inputs), -2, has two y-values (inputs), 1 and 3.
Therefore, the set of points does not represent a function.

here's the question
Answer:
60
Step-by-step explanation:
perimeter (p) = 8 + 17 + 15 = 40
semi-perimeter (s) = p/2 = 20
Area = square root of s(s-a)(s-b)(s-c) where a,b,c are the sides of the triange by Herons formula.
Therefore, area = 20(20-8)(20-15)(20-17) = square root of 3600 = 60
