What is the area of ABCDE?____sq cm
got very confused on this part
Answer:
A= 30 sq. cm
Step-by-step explanation:
We want to find the area of both triangles seprately than add them together. For the area of a traingle, we use the equation 1/2 base times height. For triangle ABE we do this:
[tex]A = \frac{1}{2} (12)(4)[/tex]
[tex]A = (6) (4)[/tex]
[tex]A = 24[/tex]
For triangle BDC, we do this:
[tex]A = \frac{1}{2} (6) (2)[/tex]
[tex]A = (3) (2)[/tex]
[tex]A=6[/tex]
Now we have to add both areas ot get A=30 sq cm

Aright triangle with an area of X2-4 square units has a leg that measures
2x + 4 units.
Determine the length of the other leg of the triangle.
Answer:
x - 2
Step-by-step explanation:
First, we know that the area of a triangle can be found using the formula: a = 1/2(bh).
We also know that the area of this triangle can be represented by (x^2-4).
Lastly, we know that one of the legs (let's call it the base) can be represented by (2x+4).
Let's plug in those values to the original formula: x^2 - 4 = 1/2(2x + 4)h
Now, let's solve for h!
We can multiply both sides by 2, then divide each side by (2x + 4) to isolate/solve for h.
If you need help on dividing polynomials, feel free to reach out!! I'd be happy to explain.
h = (x - 2)

A ladder, leaning against a wall, makes an angle of 20° with the ground. The foot of the ladder is 3 m from the wall. How long is the ladder?
Answer:
0.136m
Step-by-step explanation:
This is because if you draw a diagram, and label all the sides of the triangle (opp, hyp, adj), the adjacent angle is 3m. You can now use the sine rule to find the hypotenuse (length of ladder) by doing: cos 20= 3/h. You divide cos(20) by 3 and you get the answer of 0.13602m.
For each right triangle fine the length of the side that is not given. Round your answer to the nearest tenth.(one Decimal place)
Answer:
√157
Step-by-step explanation:
Use Pythagorean theorm.
[tex]11^2 + 6^2 = ?^2[/tex]
121 + 36 = ?^2
157 = ?^2
√157 = ?
Can't simplify.
Answer:
12.5 m
Step-by-step explanation:
You are given the lengths of the legs of a right triangle.
We can use the Pythagorean theorem to find the length of the hypotenuse.
a^2 + b^2 = c^2
(6 m)^2 + (11 m)^2 = c^2
36 m^2 + 121 m^2 = c^2
c^2 = 157 m^2
c = sqrt(157 m^2)
c = sqrt(157) m
Answer: 12.5 m

The solution to 2x2 – 11 = 87 is .
Step-by-step explanation:
Step 1: Subtract 87 from both sides
[tex]2x^2 - 11 - 87 = 87 - 87[/tex]
[tex]2x^2 - 11 - 87 = 0[/tex]
Step 2: Factor
[tex]2x^2 - 11 - 87 = 0[/tex]
[tex]2(x + 7)(x - 7) = 0[/tex]
[tex]x + 7 = 0[/tex] and [tex]x - 7 = 0[/tex]
[tex]x = -7[/tex] and [tex]x = 7[/tex]
Answer: [tex]x = -7, 7[/tex]
Answer:
x = 7, -7
Step-by-step explanation:
2x² - 11 = 87
2x² = 98
x² = 49
x = +/-7
A spinner has 5 equal-sized sections with different colors. You spin the spinner 50 times. The results are shown in the table. Find the theoretical and experimental probabilities of spinning blue.
Red Green Blue Yellow Orange
8 11 15 9 7
The theoretical probability is
.
The experimental probability is
.
Question 2
What do you think will happen to the experimental probability when you spin the spinner 400 times?
The experimental probability will stay the same.
The experimental probability will get farther from the theoretical probability.
The experimental probability will get closer to the theoretical probability.
Answer:
a) If the spinner is fair, then each color must have the same probability, this means that the probability for each color is the number of times that the color (in this case blue) is in the spinner divided the total amount of colors in the spinner, then the theoretical probability for each color is:
Pt = 1/5 = 0.20
The experimental probability can be found by dividing the number of times that the spinner landed on a given color (in this case for blue we have 15 times) divided the total number of spins ( 50)
Pe = 15/50 = 0.30
B) As we increment the number of spins, we should see that the experimental probability gets closer to the theoretical probability.
A 4 1/2 ounce hamburger patty has 25 1/2 grams of protein. Determine the grams of protein per ounce each type of food.
Select from the drop down menus to correctly complete each statement
Answer:
Option c. 5.7 grams
Option b. 5.3 grams
Step-by-step explanation:
(a) A [tex]4\frac{1}{2}[/tex] ounce hamburger patty has [tex]25\frac{1}{2}[/tex] grams of protein.
first we convert mixed fraction to improper fraction.
Amount of protein a [tex]\frac{9}{2}[/tex] ounce hamburger patty has = [tex]\frac{51}{2}[/tex] grams
∴ Amount of protein a 1 ounce hamburger patty has = [tex]\frac{\frac{51}{2} }{\frac{9}{2} }[/tex]
= [tex]\frac{51}{2} \times \frac{2}{9}[/tex]
= [tex]\frac{51}{9}[/tex]
= [tex]\frac{17}{3}[/tex] = [tex]5\frac{2}{3}[/tex] = 5.7 grams
(b) A 6 ounces of fish has 32 grams of protein.
∴ The amount of protein a 1 ounce of fish has = [tex]\frac{32}{6}[/tex]
= 5.3 grams
A hamburger patty has approximately 5.7 grams of protein per ounce.
A fish has approximately 5.3 grams of protein per ounce.

Answer:
(x + 5)² + (y - 7)² = 13
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (- 5, 7) and r = [tex]\sqrt{13}[/tex] , thus
(x - (- 5))² + (y - 7)² = ([tex]\sqrt{13}[/tex] )² , that is
(x + 5)² + (y - 7)² = 13 ← equation of circle
