Answer:
x = 14√3
y = 7√3
Step-by-step explanation:
By applying sine rule in the given triangle,
sin(60°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{\sqrt{3} }{2}=\frac{21}{x}[/tex]
x = [tex]\frac{42}{\sqrt{3}}[/tex]
x = 14√3
By applying cosine rule in the given triangle,
cos(30°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{2}=\frac{y}{x}[/tex]
[tex]\frac{1}{2}=\frac{y}{14\sqrt{3}}[/tex]
y = 7√3

Step-by-step explanation:
The total area can be calculated by splitting this irregular shape into two quadrilaterals.
In this case, I am splitting it horizontally, but you can do it vertically and get the same answer!
I'm left with a 10 by 8 ft rectangle and an 15 by 4 ft rectangle. So, the total area is equivalent to:

Answers
Answer:
C. 75
Step-by-step explanation:
First, list the multiples of each numbers and stop when you reach the least common multiple (the smallest number the numbers can multiply up to):
5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75 . . .
25: 25, 50, 75 . . .
15: 15, 30, 45, 60, 75 . . .
5 times 15 is 75, 25 times 3 is 75, and 15 times 5 is 75. Their LCM is 75.
please help me, I'm stuck on the second one. Also for i) i got angle ABD because angles in a semicircle measures 90 degree and OAX because the angle between the tangent and a radius is 90 degrees
Answers
Answer:
i)
DA is diameter and AX is tangent to circleYour answer is correct
m∠ABD = 90°, m∠DAX = 90°ii)
Given m∠BAX = 42° and ∠DAB is complementary with BAX ⇒
m∠DAB = 90° - 42° = 48°DC = BC ⇒ intercepted arcs are same ⇒
∠CDB = ∠BDCmDC = mCB ⇒ mDCB = ∠DAB = 48° ⇒
m∠CDB = m∠BDC = 1/2*48 = 24°iii)
∠CBA
∠CBA is supplementary with ∠ADC as opposite angles of cyclic quadrilateral (∠ADB = ∠BAX = 42°)
m∠ADC = m∠ADB + m∠CDB = 42° + 24° = 68°m∠CBA = 180° - m∠ADC = 180° - 68° = 112°∠BAE
EA║CB and AB is transversal ⇒ CBA and BAE are supplementary angles:
m∠BAE = 180° - 112° = 68°∠DCE
∠DCE = ∠DCB - ∠BCEm∠DCB = 180° - m∠DAB = 180° - 48° = 132°m∠BCE = 180° - m∠BAE = 180° - 68° = 112°∠DCE = 132° - 112° = 20°Write the ratios for sin A and cos B. 10 AC, 24 CB, 26 BA

A taxi driver charges you $1.50 for the first mile and $.90 for each additional mile. How far could you go for $20.00 if you give the driver a $2.00 tip?
Answers
Answer:
You can go 19.33 miles for $20.00 if you give the driver a $2.00 tip.
Step-by-step explanation:
From the information provided, you can say that the total cost of the taxi is equal to the cost of the first mile plus the price for each additional mile for the number of additional miles, which can be expressed as:
c=1.50+0.90(x-1), where
c is the total cost
x is the number of miles
Now, if you want to determine how far you can go for $20 if you give the driver a $2.00 tip, first you have to subtract the tip from the amount you have:
20-2=18
Then, you know that you have $18 for the cost of the taxi and you can replace c with this value and solve for x to find the number of miles:
18=1.50+0.90(x-1)
18-1.50=0.90x-0.90
16.5+0.90=0.90x
17.4=0.90x
x=17.4/0.9
x=19.33
According to this, the answer is that you can go 19.33 miles for $20.00 if you give the driver a $2.00 tip.
Answer:
You can go 19.33 mile

Answers
Answer:
-8/3
Step-by-step explanation:
2 - x = - 6 - 4x <-- Add 4x to the left side
2 + 3x = - 6 <-- Subtract 2 from the left side
3x = -8 <-- Divide 3 on both sides
x = -8/3
Answer:
x = -8/3
Step-by-step explanation:
Consolidate x terms on the right side:
2-x= -6-4x becomes 2-x + x = -6-4x + x, which in turn becomes:
2 = -6 - 3x, or 3x = -8. Then, dividing both sides by 3, we get x = -8/3

The probability of rolling a number cube and getting a 6 and 3.
Answers
We have to find out the probability of getting 6 and 3,
Since this only one roll it is not possible to get 2 numbers in one roll
So, I will presume you want the probability of getting 6 or 3,
Total number of outcomes= {1,2,3,4,5,6} = 6 outcomes
Number of favorable outcomes = {3,6} = 2 outcomes
Probability of rolling 6 or 3 = [tex]\frac{Number'of 'favorable' outcomes}{Total' number 'of' outcomes}[/tex]
= 2/6
= 1/3 or 0.33333%
Therefore the probability of rolling 6 or 3 is one in three chances
