Answer:
The measure of ∠BAC is 30°
Step-by-step explanation:
Given:BAC = (x + 10)°
DAE = (2x - 10)°
Here, BAC and DAE are vertical angles, So they are equal
BAC = DAE
(x + 10)° = (2x - 10)°
x + 10° = 2x - 10°
Subtract 10° and 2x from both side we get,
x + 10° - 10° - 2x = 2x - 2x - 10° - 10°
-x = -20°
x = 20°
Here, The value of x is 20°
Now, We want to find ∠BAC
So,
∠BAC = (x + 10)° = 20° + 10° = 30°
Thus, The measure of ∠BAC is 30°

A wedding ring costs £13000. Work out the price after a 11% price increase
Answers
13,000 x 1.11 (111%) = 14430
Answer:
Step-by-step explanation:
Increased price = 11% of £ 13000
= 0.11 * 13000
= 1430
Price after increase = 13000 + 1430 = £ 14,430
Sarah can make a lemonade drink by mixing 3 cups of lemonade powder with 7 cups of water are necessary to make five lemonade drinks
Answers
Let’s also say that one cup of lemonade is (L)
Since you need 3 cups of (p) and 7 cups of (w) to make 1 of (L), the equation would be f(L) = 3p + 7w
The (L) would be input of how many cups you need
So if you need 5 cups, use 5 as your input
F(5) =3(5)+7(5)
3x5=15
7x5=35
You need 15 cups of Lemonade powder
And 35 cups of water

At Kenner Country Club, 45% of the members swim. If 3 people are selected at random, what is the probability that all three will say they swim at the club?
Answers
Step-by-step explanation:
so, we pick the first one. the probability this person swims is 0.45.
if yes, then we pick the second one. this one has also a probability of swimming of 0.45.
combined with the probability of the first one being a swimmer this is now 0.45×0.45.
the same with the third pick.
and we have the probability that all 3 swim of
0.45×0.45×0.45 = 0.45³ = 0.091125
that is rounded about 0.09 or 9%.

I have attempted this and keep on getting about -0.28, but that is not an option.

If
[tex]\dfrac{dh}{dt} = -\sqrt{5h} = -\sqrt{5} \cdot h^{\frac12}[/tex]
then its derivative, using the power rule, is
[tex]\dfrac{d^2h}{dt^2} = -\sqrt{5} \cdot \dfrac12 h^{1-\frac12} = -\dfrac{\sqrt5}2 h^{-\frac12} = -\dfrac{\sqrt5}{2\sqrt h} = -\sqrt{\dfrac{5}{4h}}[/tex]

How many 1/5 cup servings are in
5 3/8 cups? Show your work.
Answers
Answer:
butt
Step-by-step explanation:
Step-by-step explanation:
what do we do, if we want to know how often something fits into another thing ?
we divide.
as we want to know how many 1/5 cups fit into 5 3/8 cups.
so,
(5 3/8) / (1/5)
5 3/8 = (8×5+3)/8 = 43/8
(43/8) / (1/5)
now we also know : dividing by a fraction is the same as multiplying with the upside-down fraction.
(43/8) × (5/1) = (43/8) × 5 = 43×5/8 = 215/8 = 26 7/8
so, there are 26 1/5 cups servings in 5 3/8, with a remainder of 7/8 of a 1/5 cup = 7/8 × 1/5 = 7/40 cup.
Find the area of the shaded region. Round your answer to the nearest hundredth.
12=side length
The area of the shaded region is about — square units.
How do you find the area of the shaded region? Thank you!
Answers
Answer:
Step-by-step explanation:
Divide 360 by the number of sides in a regular polygon to find θ
θ = 360/5 = 72°
Use law of cosines to find the radius of the circle which equals the common length sides of the isosceles triangle
12² = R² + R² - 2•R•Rcos72
12² = 2R² - 2R²cos72
12² = 2R²(1 - cos72)
R² = 12² / 2(1 - cos72)
R² = 104.1993788...
R = 10.2078...
The height of the isosceles triangle is
h = Rcos(θ/2) = 10.2078cos(72/2) = 8.258291...
The shaded area is the area of the circle minus the area of the pentagon.
A = π(104.1993) - 5(½(12)(8.258291))
A = 327.35200... - 247.74874...
A = 79.6032575...
A = 79.60 units²
The Area of the shaded region is A = 79.60 units²
What is law of Cosine?A planar triangle's side's square is equal to the sum of the squares of the other sides minus the product of those sides and the cosine of the angle that separates them by two.
Given:
length= 12
So, Divide 360 by the number of sides in a regular polygon
θ = 360/5
θ = 72°
Use law of cosines
12² = R² + R² - 2 x R x Rcos72
12² = 2R² - 2R² cos72
12² = 2R²(1 - cos72)
R² = 12² / 2(1 - cos72)
R² = 104.1993788...
R = 10.2078...
Thus, the height of the isosceles triangle is
h = R cos(θ/2)
= 10.2078cos(72/2)
= 8.258291...
and, the shaded area is
A = π(104.1993) - 5(½)(12)(8.258291))
A = 327.35200 - 247.74874
A = 79.6032575
A = 79.60 units²
