Answer:
6 m
Step-by-step explanation:
36 m^2 = bh/2
36·2 = bh/2·2
72 = bh
72 = 12·6
check
36 m^2 = 12·6/2
36 = 36

then;
tan68 = opposite/adjacent
tan68 = 15/x
x = 15/tan68
x = 6.06
If anyone can help me I’d be glad. I’m not the best at geometry :/
Answer:
C) 1.25
Step-by-step explanation:
The hypotenuse is the sloping side.
The base is the bottom side.
The triangles are similar, so you can use the sides of either triangle. Let's use the side lengths of the smaller triangle.
Length of hypotenuse: 5
Length of base: 4
Ratio of hypotenuse to base: 5/4
To find a decimal value, divide 5 by 4. Use a calculator or long division.
5/4 = 1.25
Answer: C) 1.25

Answer:
6 and 8 cm
Step-by-step explanation:
As both are similar, ratio of correspondening sides must be constant.
10/5 = x/3 = y/4
2 = x/3 = y/4
Thus,
x = 2*3 = 6 cm
y = 2*4 = 8 cm

if the Diameter of a can 6 inches an the Height of the can is 4 inches Volume of Can , Surface Area of Can ,and Ratio of Surface Area to Volume
we know that
diameter of the base of a cylindrical can= 4 in----------> r=2 in
h=6.5 in
[surface area]=2*[pi*r²]+[2*pi*r*h]
then
[surface area]=2*[pi*2²]+[2*pi*2*6.5]=[ 25.13 ]+[ 81.68 ]=106.81 in²
the answer is 106.8 in²

Answer:
number B (4×4)+(3×3×3)= 43
Answer:
B. 4² + 3³
Step-by-step explanation:
I'll do each of these expression to see which one equals 43.
2⁴ + 3²
16 + 9
25 ≠ 43; So A is out.
5² + 5³
25 + 125
150 ≠ 43; so C is out.
3² + 2³
9 + 8
17 ≠ 43; so D is out.
4² + 3³
16 + 27
43 = 43, so B is the answer to this question.
Geometry inscribed angle
find angle x
9514 1404 393
Answer:
x = 5
Step-by-step explanation:
The arc subtended by the marked angle is ...
360° -226° = 134°
The measure of the marked angle is half this, so we have ...
15x -8 = 134/2
15x = 75 . . . . . . . add 8
x = 5 . . . . . . divide by 15
somone know how to do this??

The amount of a radioactive isotope decays in half every year. The amount of the isotope can be modeled by f(x) = 346(one half)x and f(1) = 173. What does the 173 represent?
9514 1404 393
Answer:
f(1) = 173 = the amount remaining after 1 year
Step-by-step explanation:
The function definition tells you f(x) is the amount of the isotope remaining after x years. Then ...
f(1) = 173 = the amount remaining after 1 year
__
(no units are given, so we don't know if that is 173 nanograms, or 173 truck loads)
find the measure of 2 and 4 if 1=122° and 3 = 58°
Answer:
Due to lack of details, I can come up with several possible answers
if 2 is opposite from ∠3, then ∠2 = 58°
if 2 is opposite from ∠1, then ∠2 = 122°
if 4 is opposite from ∠3, then ∠4 = 58°
if 4 is opposite from ∠1, then ∠4 = 122°
Somone PLEASE answer this thanks!
A movie complex is showing the same movie in three theaters. In theater A, 44 of the 80 seats are taken. In theater B, 42 seats are taken and 28 seats are empty. In theater C, 27 of the 90 seats are empty. Which theater has the greatest percent of its seats taken? Which theater has the greatest of its seats taken ?
Answer:
Theater C
Step-by-step explanation:
Theater A has 80 seats, 44 of which are taken. 44/80 can be simplified to 11/20, which is 0.55 in decimal form, and 55% in percent form.
Theater B has 70 seats, because 42+28 = 70. 42 of those 70 seats are taken. 42/70 is 60%
Theater C has 90 seats, and because 27 are empty, we can subtract 27 from 90, which leaves us at 63 seats are taken. 63/70 is 70%
70% is the biggest percentage, so Theater C has the greatest seats taken.
I hope this helps! :))

Answer:
78°
Step-by-step explanation:
From the diagram,
Applying sine rule,
SinA/a = sinC/c................... Equation 1
Given: c = 29 cm, C = 50°, a = 37 cm
Substitute into equation 1 and solve for A.
sinA/37 = sin50°/29
sinA = (37×sin50°)/29
sinA = (37×0.766)/29
sinA = 28.34/29
sinA = 0.9774
A = sin⁻¹(0.9774)
A = 77.8°
A ≈ 78°
Hence the measure of angle A = 78°

Answer:
B) 20°
Step-by-step explanation:
The top half of the circle is equal to 180°...
13x + 3x + 2x = 180°
18x = 180°
x = 10°
Angle EOD is the opposite angle of 2x
2 (10) = 20°

You deposit $2000 in an account that pays 7% interest compounded semiannually. After 5 years, the interest rate is increased to 7.28% compounded quarterly. What will be the value of the account after a total of 10 years?
The value of the account will be $_____. (Round to the nearest dollar as needed.)
9514 1404 393
Answer:
$4047
Step-by-step explanation:
For an interest rate r compounded n times per year for t years, the effective multiplier is ...
(1 +r/n)^(nt)
The multiplier for the first 5 years is ...
(1 +0.07/2)^(2·5) = 1.41059876
The multiplier for the last 5 years is ...
(1 +0.0728/4)^(4·5) = 1.43437218
Then the account value at the end of 10 years is ...
$2000(1.41059876)(1.43437218) ≈ $4047 . . . . balance after 10 years

Answer:
what are the equations?
Step-by-step explanation:
What is the slope of the lines that are parallel to the line defined by the equation y = -x – 4?
Answer:
slope = -1
Step-by-step explanation:
parallel lines have the same slope,
y = -x – 4
=> y = -1(x) -4
↑ slope
y = mx + b
↑ slope
