Answer:
54 unit^2.
Step-by-step explanation:
The area = the sum of the 2 triangles.
Area of a triangle = 1/2 * base * height.
So here:
A = 1/2 * 4 * 12 + 1/2 * 5 * 12
= 24 + 30
= 54
Answer:
ABCD = 54 u²Explanation:
the area of the polygon = the area of the triangle ADC + the area of the triangle ABC
the area of a triangle = (height × base)/2
A ADC = (DE×AC)/2
A ADC = (4×12)/2
A ADC = 48/2
A ADC = 24 u²
A ABC = (BF×AC)/2
A ABC = (5×12)/2
A ABC = 60/2
A ABC = 30 u²
ABCD = A ADC + A ABC
ABCD = 24 + 30
ABCD = 54 u²

Josh is driving from his house to his grandmother's house. If 1/3 gallon of gasoline will get Josh 1/9 of the way to his grandmother's, how many gallons of gasoline does Josh need for the entire trip?
Answers
Answer:
3 Gallons
Step-by-step explanation:
Answer:
3 gallons
Step-by-step explanation:
Given: 1/3 gallon needed for 1/9 of the whole trip
To find: How many gallons of gasoline Josh needs for the entire trip
Solve: Firstly, we need to find out the entire trip as a fraction
1/1
If 1/9 = 1/3, then 1/1 = 1/9 ÷ 1/3 = 0.33
No, multiply that by 1/1
1/1 × 0.33 = 0.33
Then, convert 0.33 to a whole number
Hence, Josh needs 3 gallons for the entire trip

Step-by-step explanation:
Firstly, Let's identify the amount per day as show by the problem that is 3/10.
In simple terms, the question requires us to find the amount of calcium 3 glasses would provide.
Well, if one glass provides 3/10.
To find the value of three glasses, we need to multiply!
[tex]\frac{3}{10}*3\\\frac{3}{10}*\frac{3}{1}[/tex]
The amount of calcium three days would provide is [tex]9/10[/tex].

What type of triangle is ABC?
Give reasons for your answer.
Answers
Answer:
I'll say that it is a scalene triangle because all of the sides of the triangle have different lengths.
Angle CAB is congruent to angle ACD because they are alternate interior angles (note the parallel lines AB and DE). So this makes angle CAB to be 50 degrees.
For similar reasoning, angle BCE = angle ABC = 80 degrees.
Focus on the angles that are centered at point C. Those three angles form a straight line so they add to 180 degrees.
(angle ACD) + (angle ACB) + (angle BCE) = 180
(50) + (angle ACB) + (80) = 180
(angle ACB) + 130 = 180
angle ACB = 180-130
angle ACB = 50 degrees
Ultimately, this leads to triangle ABC having the interior angles of A = 50, B = 80 and C = 50.
Because we have exactly two interior angles that are the same measure, this must mean triangle ABC is isosceles. The congruent angles are opposite the congruent sides, meaning that AB = BC.

The height h, in feet, that an arrow will reach 1 seconds after being shot directly upward is given by the formula h = 1121 - 1612
How high will the arrow be after 4 seconds?
Answers
Answer:
4484 - 6448
Step-by-step explanation:
Given: 1 second = 1121 - 1612.
To find: How high the arrow will be after 4 seconds.
Solution:
If 1 second = 1121 - 1612, then 4 seconds = 4 × 1
4 × 1121 - 1612 = 4484 - 6448
Therefore, the arrow will be as high as 4484 - 6448 in 4 seconds.

This price includes the cost of labor and the cost of the parts needed to do the repairs. If labor costs are 3/5 the cost of the parts, how much would you save by doing the repairs yourself and just purchasing the parts?
Answers
Answer:
you save labor : 3562.50
Step-by-step explanation:
You want to calculate for labor.
labor = 3/5 (parts)
labor + parts = $9500 (total costs)
3/5 parts + parts =9500
3/5 parts + 5/5 parts = 9500
8/5 parts=9500
5/8(8/5 parts) = 5/8 (9500)
‘parts = 5937.50
labor=3562.50 (3/5 x 5937.50)
total = 9500

a). m∠WAX = 60°
If m(arc WX) = 100°
Then by theorem,
Angle formed between the chords in a circle, measures the half of the sum of intercepted arcs.
m(∠WAX) = [tex]\frac{1}{2}(\text{arc WX + arcYZ})[/tex]
60° = [tex]\frac{1}{2}(100+\text{arcYZ})[/tex]
120 = 100 + arc YZ
120 - 100 = arc YZ
m(arc YZ) = 20°
b). m(arc WX + arc YZ) = 2(60°)
m(arc WX + arc YZ) = 120°

Answer:
Each triangle weighs 3 grams.
Step-by-step explanation:
On the left side, there are 6 squares (12 grams) 3 circles (9 more grams), and 2 triangles (2x grams).
On the right side, there are 3 squares (6 grams) 2 circles (6 grams), and 5 triangles (5x grams).
This makes the equation 21 + 2x = 12 + 5x.
Let's find x.
21 + 2x = 12 + 5x
Subtract 5x from both sides.
21 - 3x = 12
subtract 21 from both sides.
-3x = -9
Divide by -3.
x = 3.
Each triangle weighs 3 grams. Let's prove this.
21 + 2x = 12 + 5x
21 + 2(3) = 12 + 5(3)
21 + 6 = 12 + 15
