Answer:
54 3/10 inches tall
Step-by-step explanation:
1 1/6 + 1 1/3 = 2 1/2
53 4/5 + 2 1/2 = 54 3/10
The height of Sheila is 62 ²³/₃₀ inches. Then the height of Jane will be 83 ³¹/₄₅ inches.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Cole is 53 ⁴/₅ inches tall. Sheila is 1 ¹/₆ inches taller than Cole. Then the height of Sheila is calculated as,
⇒ (53 ⁴/₅) × (1 ¹/₆)
⇒ 62 ²³/₃₀
Jane is 1 ¹/₃ inches taller than Sheila. Then the height of Jane is calculated as,
⇒ (62 ²³/₃₀) × (1 ¹/₃)
⇒ 83 ³¹/₄₅ inches
The height of Sheila is 62 ²³/₃₀ inches. Then the height of Jane will be 83 ³¹/₄₅ inches.

A right angled triangle is a triangle (has three sides and three angles) in which one of the angles measure 90°.
Trigonometric ratios is used to show the relationship between the sides of the right angled triangle and its angles.
Let h represent the height of the cliff. Let θ = 90 - 49 = 41°. Hence:
tan(41) = 17/h
h = 17 / tan(41) = 19.6 m
Therefore the cliff is 19.6 m tall

The cross section of a water bin is shaped like a trapezoid. The bases of the trapezoid are 22 feet and 14 feet long. It has an area of 54 square feet. What is the height of the cross section?
Answer:
h = 3 feet
Step-by-step explanation:
Given that,
The bases of trapezoid are 22 feet and 14 feet long.
The area of trapezoid is 54 square feet.
We need to find the height of the cross section. The formula for the area of trapezoid is given by :
[tex]A=\dfrac{1}{2}(\text{sum of parallel sides})\times h\\\\54=\dfrac{1}{2}\times (22+14)\times h\\\\54=\dfrac{1}{2}\times 36\times h\\\\54=18h\\\\h =\dfrac{54}{18}\\\\h=3\ feet[/tex]
So, the height of the cross section is 3 feet.

Lula is reading a book for school that is 175 pages long. So far, she has read 50 pages. She can read 25 pages per hour. How many hours will it take her to finish the remainder of the book? Which answer choice best represents the unknown quantity in this problem ?
Answer: 5 hours
Step-by-step explanation:
She has already read 50 pages so we need to deduct that to calculate the answer:
= 175 - 50
= 125 pages left
She can read at a speed of 25 pages per hour. The number of hours it would take to read the remainder of the book would therefore be:
= 125 pages / 25 pages per hour
= 5 hours

What is the slope-intercept equation for this
standard form equation?
(Y-intercept needs to be positive)-
(Giving Brainliest for Correct Answer-)
6x - 3y = 12
Answer:
Y = 2x - 4
Slope is 2.
Y-intercept is -4.
Step-by-step explanation:
To find slope in standard form, take -A/B. So 6 is A, -3 is B. -(6/-3) = 2.
And to find the y-int, take C/B. C is 12. So, 12/-3 = -4.
Or you could also rearrange the equation. . .
6x - 3y = 12.Subtract 6 from both sides. -3y = -6x + 12Divide by -3 to isolate the y. y = 2x - 4.Which expression shows the result of applying the distributive property to −2(13x−15)?

What is the volume of the prisms below?
What equation would you use for the last picture?
Answer:
8) 131.118in^3
9) 18cm^3
Step-by-step explanation:
8) Volume of the prism = Length * Width * height
Volume of the prism = 4.1in * 8.2in * 3.9in
Volume of the prism = 131.118in^3
Hence the volume of soil that will fill the prism is 131.118in^3
9) Volume of the triangular prism = Base Area * Height of prism
Base Area = 1/2bh
Base Area = 1/2 * 4 * 3
Base Area = 6cm^2
Height of the prism = 3cm
Volume of the prism = 6cm^2 * 3cm
Volume of the prism = 18cm^3

Answer:
53.44 cubic meters
Step-by-step explanation:
A cylindrical oil drum is 2.1 meters high and has a radius of 0.9 meters. How many cubic meters of oil can the drum hold? (volume)
Volume of a cylinder = π × r² × h
r = 0.9 meters
h = 2.1 meters
= π × (0.9m)² × 2.1m
= 53.44 cubic meters
Therefore, the volume of the cylindrical oil drum = 53.44 cubic meters

Copy the shape and fill in the missing angle. Sow the work. Thanks.
Answer:
The first triangle can be solved using the triangle sum theorem.
There is a vertical angle, so 75 is the angle at the bottom left. 45 is also a vertical angle. Now we have 75+45+x=180, where x is the missing angle. x is 60.
A straight line = 180 degrees, so 60+79+y, where y is unknown, is equal to 180. y is 41. Now use the triangle sum theorem for the triangle to the right. 41+68+z, where z is unknown, = 180. Z is 71.
Now the last part is to find the question mark. A straight line is 180 degrees, so 71+"?" is 180. Simplify to find that "?" is 109.

Why does sin30° equal 1/2?
Step-by-step explanation:
it's easy to prove in any right triangle with a 30° angle, the side opposite to that angle is half the hypotenuse. CA (1/2)BC, CA/BC=1/2
Step-by-step explanation:
Take an equilateral triangle of side.
Bisec it through a vertex and the midpoint of the opposite side.
You now have two right-angled triangles with angels 30° , 60°, 90° with the edge opposite the 30° of length 1/2 and hypotenuse 1. So
sin (30°) = 1/2/1= 1/2.
Answer: The right angled triangle you describe has angels of 45 degrees, not 30 degrees.
What you proved is sin 45 = 1\2 , which is correct.

Find two numbers whose product is 25 and whose sum is -10
A product is an answer to a multiplication problem and sum is the answer to an addition problem.
25 is the product, and -10 is the sum.
Factors of 25 is 5 and 5.
-5+-5=10.
But two negatives multiplied equals a positive.
-5 x -5=25
-5 + -5 = 10

hope it helps
Answer:
The two numbers are -5 and -5
Step-by-step explanation:
Let x and y be the two numbers respectively
xy = 25 --(1)
x + y = -10 --(2)
From (1), x = 25/y [You get x in terms of y]
Sub x = 25/y into (2)
25/y + y = -10 [Equation (2) is x + y = -10, but you got x = 25/y]
[Multiple the whole equation by y]
25 + y^2 = -10y
y^2 + 10y + 25 = 0 [This is a quadratic equation if you don't know]
y = -5
Sub y = -5 into (1)
x = -5

Answer:
a) BD = 5
b) FD = 13
Step-by-step explanation:
For both questions we follow pythagoras therom.
For the first one we do 3^2 +4^2 = 25 and then we root this answer to 5
For the second we have to find the base of GD in order to find FD. GD will be 4^2+12^2 which equals to 160 and then you root.
Finally, we can find FD which is sqaure root of 160^2 + 3^2 = 169. The square root of 169 is 13. Answer is 13.
Answer:
Step-by-step explanation:
AD =BC = FG = EH = 3
AB = DC = EF =HG = 4
BF =AE = DH = CG = 12
Use Pythagorean theorem,
Hypotenuse² = base² +altitude²
BD² = DC² + BC²
= 4² + 3²
= 16 + 9 = 25
BD = √25
BD = 5
DG² = DC² + CG²
= 4² + 12²
= 16 + 144
= 160
FD² = DG² + FG²
= 160 + 3²
= 160 + 9
= 169
FD = √169 = 13
FD = 13
