A= 1/2 bh
Select one
A. 9
B. 12
C. 11
D. 5
Answer:
option B
Step-by-step explanation:
let the height=x
base=x
Area=½bh
72=½x•x
72×2=x²
144=x²
x=√144=12
Answer:
12
Step-by-step explanation:
12 x 12= 144
144/2= 72

Step-by-step explanation:
Kelsea and Landon are playing in a park standing 100 feet away from each other. They both see a bird flying above them. The angles of elevation from each person to the bird are shown. How high is the bird from the ground? Round your answer to the nearest tenth. The angle for landon is 45 degrees the angle for kelsea is 20
Answer:
26.68 ft
Step-by-step explanation:
Let a represent the distance from Kelsea to the bird and b be the distance from Landon to the bird.
Let x = angle of the bird. Hence:
x + 45 + 20 = 180 (sum of angles in a triangle)
x + 65 = 180
x = 180 - 65
x = 115°
Using sine rule:
[tex]\frac{100\ ft}{sin(115)} =\frac{a}{sin(45)} =\frac{b}{sin(20)} \\\\\frac{100\ ft}{sin(115)} =\frac{a}{sin(45)}\\\\a=\frac{100\ ft}{sin(115)} *sin(45)\\\\a=78\ ft\\[/tex]
Let h = height of the bird to the ground. Since a right angle is formed. hence:
[tex]\frac{h}{sin(20)} =\frac{78}{sin(90)} \\\\h=\frac{78}{sin(90)}*sin(20)\\\\h=26.68\ ft[/tex]

CHARITY This year, James raised $95 for an animal shelter. This is 5
times the amount he saved. The equation 5x = 95 can be used to find last
year's fundraising amount. Find last year's fundraising amount.
Please help I have know clue what to do!!
Answer: Hi, sorry if I’m late to answering but the answer is 19
Step-by-step explanation:
You divide each number in the equation by 5. So, 5x divided by 5 = 1. We cannot use 5 divided by 5 because it will equal 1 so we ignore that and go to 95 divided by 5 = 19. Therefore, 19 is your answer!!! (Hope this helped)

Answer:
(1). x = 14 ; (2). 70°
Step-by-step explanation:
(1). m∠ACD = m∠A + m∠B
6x + 2 = (2x + 1) + (3x + 15)
6x - 5x = 14
x = 14
(2). m∠ABC = 180° - m∠CBD = 140°
m∠A = m∠C = 140° ÷ 2 = 70°

(B). 64a^3-144a^2b+108ab^2-27b^3
Plz answer, it's urgent.
Answer:
a)(5m+3n)^3 b)(4a-3b)^3
Step-by-step explanation:
a)125m^3+27n^3+225m^2 n+135mn^2
Use the binomial cube formula, a^3+3a^2
b+3ab^2+b^3=(a+b)^3, where a=5m and b=3n.
(5m+3n)^3
b)64a^3-144a^2 b+108ab^2-27b^3
Use the binomial cube formula, p^3-3p^2q+3pq^2-q^3=(p-q)^3, where p=4a and q=3b.
(4a-3b)^3
What is the area of the circle ?
Answer:
113.04 [tex]m^{2}[/tex]
Step-by-step explanation:
Area of a circle is π x [tex]r^{2}[/tex].
I'm assuming that you're using 3.14 as π.
Since the radius of the circle is 6 m, all you need to do is plug it in!
Area = 3.14 × [tex](6)^{2}[/tex]
Area = 3.14 × 36
Area = 113.04 [tex]m^{2}[/tex], which is the third answer choice.
What is the value for x=
Answer:
x = 2[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Since the 2 legs are congruent, both 6 then the triangle is isosceles.
The line from the vertex to the base is a perpendicular bisector, dividing the base into 2 parts of 4 units.
Using Pythagoras' identity in one of the right triangles.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 4² = 6²
x² + 16 = 36 ( subtract 16 from both sides )
x² = 20 ( take the square root of both sides )
x = [tex]\sqrt{20}[/tex] = [tex]\sqrt{4(5)}[/tex] = 2[tex]\sqrt{5}[/tex]

Need HELP ASSAP -8/5 times -5/1
Answer:8
Step-by-step explanation: negative times negative =positive
and times 8/5 by 5/1 .
When multiplying fractions, simply multiply the numerators together and multiply the denominators together.
-8 * -5 = 40
5 * 1 = 5
-8/5 * -5/1 = 40/5

Doug has two German Shepherds. The
larger dog weighs 70 1/2 pounds. If the
smaller dog weighs 75% as much as the
larger dog, find the smaller dog's weight.
wait ugh i asked the wrong question help pls and thank you
Answer:
52 7/8 pounds
Step-by-step explanation:
Find the smaller dog's weight by multiplying the larger dog's weight by 0.75:
70.5(0.75)
= 52.875 or 52 7/8 pounds
So, the smaller dog weighs 52 7/8 pounds
The required weight of the smaller dog is 52.875 pounds.
Given that,
Doug has two German Shepherds. The larger dog weighs 70 1/2 pounds. If the smaller dog weighs 75% as much as the larger dog, To find the smaller dog's weight.
In mathematics, it deals with numbers of operations according to the statements.
What is percentages?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Let the weight of the smaller dog be x,
The weight of the smaller dog is 75% of the larger dog
x = 75% of 70 1/2
x = 0.75 * 70.5
x = 52.875
Thus, the required weight of the smaller dog is 52.875 pounds.
