AB = 6 cm, AC = 12 cm
Calculate the length of CD.
Give your answer to 3 significant figures.
12 cm
55°
6 cm
Answer:
12.7 cm
Step-by-step explanation:
We can obtain CB using Pythagoras :
CB = √12² - 6²
CB = √108
CB = 10.39
Using CB,
We can apply trigonometry on triangle BCD to obtain the length of CD
Sin θ = opposite / hypotenus
Sin 55 = CB / CD
Sin 55 = 10.39 / CD
CD = 10.39 / sin 55
CD = 12.68
CD = 12.7 cm
Please solve for angle C
Answer:
29

9514 1404 393
Answer:
B, D, E, A, C
Step-by-step explanation:
The main idea here is to use your English comprehension skill to determine the meaning of the phrase, then use your math understanding to write it in symbols. Turning off your brain at the sight of a "word problem" will not be productive.
The wording "some number" or "a variable" or "unknown value" all refer to a variable, typically represented by a single letter. Letters commonly use are {a, b, c, x, y, z}, but variables are not restricted to that set (nor to single letters, nor lower case letters).
In most cases, the math expression is a direct translation of the English expression using the usual math symbols. Values are generally increased by addition, decreased by subtraction, squared using an exponent of 2. A product is the result of multiplication, and a quotient is the result of division.
Top-to-bottom, the boxes on the left will be filled with B, D, E, A, C.
A drone is originally priced at 110$. The online retailer gives a discount and the drone is now $88 . enter the percentage discount for the cost of the drone.
Answer:
20%
Step-by-step explanation:
Decrease in amount = original - new amount
Decrease in amount = 110 - 88 = $22
Decrease % = decrease/original x 100%
= 22/110 x 100%
= 20%

What is the area of the triangle ?
A) 64
B) 56
C) 48
D) 112
Answer:
[tex]\text{B) }56\:\mathrm{cm^2}[/tex]
Step-by-step explanation:
The area of a triangle with height [tex]h[/tex] and base [tex]b[/tex] is given by [tex]A=\frac{1}{2}bh[/tex]. By definition, the base and the height must intersect at a 90 degree angle. Therefore, the diagram gives a base of 14 cm and a height of 8 cm. Substituting these values, we get:
[tex]A=\frac{1}{2}\cdot 8\cdot 14=\boxed{\text{B) }56\:\mathrm{cm^2}}[/tex]

x^2+2x+7=21 the approximate value of the greatest solutoon to the equation, rounded to the nearest hundreth
9514 1404 393
Answer:
x ≈ 2.87
Step-by-step explanation:
We can subtract 6 to put the equation into a form easily solved.
x^2 +2x +1 = 15
(x +1)^2 = 15
x +1 = √15 . . . . . for the greatest solution, we only need the positive root
x = √15 -1 ≈ 2.87
In order to help decide when and where to advertise, an outdoor equipment repair company decided to pull invoices and tally what types of power tools were repaired. There were twenty-five power tools repaired that month. What is the level of measurement for the data
Answer:
The answer is "nominal, qualitative".
Step-by-step explanation:
The information available is not numerically structured in a form name.
The measuring level is therefore nominal. Qualitative information is also called, which can be seen but not measured. Thus data given is qualitative.

Answer:
A = 30 inches^2
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 (b1+b2)h where b1 and b2 are the lengths of the bases
A = 1/2 ( 10+5) * 4
A = 1/2 (15)*4
A = 30 inches^2
Answer:
Area of trapezoid is 30 inches ².
Step-by-step explanation:
Question :-A trapezoid having length of Base ¹ and Base ² are 10 in. and 5 in. and it's height is 4 in. Find the area of trapezoid.
Solution :-Area of trapezoid is given by
= 1/2 × ( B¹ + B² ) × h
Where, B¹ = 10 in.
B ² = 5 in.
h = 4 in.
substitute the values
Area = 1 / 2 × ( 10 in × 5 in ) × 4 in
multiplying the values
Area = 1 / 2 × 15 in. × 4 in
Area = 1 / 2 × 60 in ².
Area = 30 in².
Hence, Area of trapezoid is 30 inches ².

Cual es la ecuación de la recta dado su pendiente m=2 y p(2,3)
Answer:
y=2x-1
Step-by-step explanation:
lim x->1+( sin(1-x)-(e^(x-1))+1)/ lnx
We're given the one-sided limit,
[tex]\displaystyle\lim_{x\to1^+}\frac{\sin(1-x)-e^{x-1}+1}{\ln(x)}[/tex]
Evaluating the limand directly at x = 1 gives the indeterminate from
(sin(1 - 1) - exp(1 - 1) + 1) / ln(1) = 0/0
so we can potentially solve the limit by applying L'Hopital's rule. Doing so gives
[tex]\displaystyle\lim_{x\to1^+}\frac{\sin(1-x)-e^{x-1}+1}{\ln(x)}=\lim_{x\to1^+}\frac{-\cos(1-x)-e^{x-1}}{\frac1x}=\frac{-\cos(0)-e^0}{\frac11}=\boxed{-2}[/tex]
The Isosceles Trapezoid is part of an Isosceles triange with a 32° vertex angle. What is the measure of an acute base angle of the trapezoid?
Answer:
[tex]b = 74^o[/tex] --- acute base
Step-by-step explanation:
Given
See attachment for the figure
Required
The acute base angle of the trapezoid
From the question, the isosceles triangle and the trapezoid share the same base.
Represent the base angle with b.
So:
[tex]b + b + 32^o = 180^o[/tex] --- angles in a triangle
[tex]2b = 180^o-32^o[/tex]
[tex]2b = 148^o[/tex]
Divide by 2
[tex]b = 74^o[/tex]

19.02797☆彡Hannain the right triangle ABC mc=90, a=4, and sinA=1/2. what is the length of the hypotenuse?
Answer:
The length of the hypotenuse is 8 units
Step-by-step explanation:
Recall the notation SOH CAH TOA. This means that in aright angled triangle,
Sin A = a/c where a is the length of the opposite side and c is the length of the hypotenuse.
Given that sinA=1/2 and a = 4, the hypotenuse c
sin A = 4/c
1/2 = 4/c
cross multiply
c * 1 = 4 * 2
c = 8 units
A parallelogram is shown below: A B A 2 foot D с 3 feet Part A: What is the area of the parallelogram? Show your work. (5 points) Part B: How can you decompose this parallelogram into two triangles? If this parallelogram was decomposed into two triangles, what would be the area of each triangle? (5 points)
9514 1404 393
Answer:
Part A: 2 ft²
Part B: draw a diagonal (AC, for example); 1 ft²
Step-by-step explanation:
Part A:
The area of a parallelogram is given by the formula ...
A = bh
where 'b' is the length of the base, and 'h' is the perpendicular distance between the bases.
Using the numbers shown on the diagram, the area is ...
A = (3 ft)(2/3 ft) = 3·2/3 ft²
A = 2 ft² . . . . . area of the parallelogram
__
Part B:
Typically, a polygon is partitioned into triangles by drawing diagonals from one of the vertices. It does not matter which one. (In a quadrilateral, only one diagonal can be drawn from any given vertex.) Here, the "base" of each triangle is the same as the base of the parallelogram: 3 feet. The "height" of each triangle is the same as the height of the parallelogram: 2/3 ft.
The area of a triangle is given by the formula ...
A = 1/2bh
A = 1/2(3 ft)(2/3 ft) = (1/2)(3)(2/3) ft²
A = 1 ft² . . . . . . . . area of each triangle
_____
Additional comment
It should be no surprise that the area of each of the two congruent triangles is 1/2 the area of the parallelogram.

Jack and Joey went to the store to buy candy. Jack bought 5 Hershey bars and 2 packs of
starbursts for $12. Joey bought 3 Hershey bars and 4 packs of starbursts for $13.50. Let x equal the cost of one Hershey bar and y equal the cost of one pack of starbursts.
8a) Write a system of equations that describes the situation above.
8b) using the equations from part a, determine the cost of one Hershey bat and the cost of one pack of starburst in dollars and cents
Answer:
5x + 2y = 12
3x + 4y = 13.50
One Hersey bar = 1.5
One pack of Starburst = 2.25
Step-by-step explanation:
Let :
Cost of one Hersey bar = x
Cost of one pack of Starburst = y
System of equation :
For Jack :
5x + 2y = 12 - - - (1)
For Joey :
3x + 4y = 13.50 - - - (2)
To determine the cost per Hersey bar and pack of Starburst
5x + 2y = 12 - - - (1)
3x + 4y = 13.50 - - (2)
Multiply (1) by 3 and (2) by 5
15x + 6y = 36 - - - (3)
15x + 20y = 67.50 - - - (4)
Subtract (4) from (3)
-14y = - 31.50
y = 31.50 / 14
y = 2.25
Using (1)
5x + 2y = 12
Put y = 2.25
5x + 2(2.25) = 12
5x + 4.50 = 12
5x = 12 - 4.50
5x = 7.50
x = 1.5
