Answer:
VT = 50√3 , PT = 50
Step-by-step explanation:
Given
PV = 100
With reference angle 60°
hypotenuse (h) = 100
perpendicular (p) = ?
Now
Sin 60° = p/h
√3 / 2 = p / 100
p = √3 * 100 / 2
p = 50√3
Also
With reference angle 30°
hypotenuse (h) = 100
perpendicular (p) = ?
sin 30° = p/h
1/2 = p / 100
p = 100 / 2
p = 50

A piggy bank contains 4 quarters, 18 dimes, 10 nickels, and 8 pennies. A coin is chosen at random, not replaced, then another is chosen. Find each probability.
P (both dimes).
Show work!!!!!
The probability of choosing two dimes consecutively without replacement is 0.196.
i.e
P (both dimes) = 0.196
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
The total number of coins.
= 4 quarters + 18 dimes + 10 nickels + 8 pennies.
= 40
The probability of choosing a dime.
= 18/40
The probability of choosing a dime without replacing the first dime.
= 17/39
The probability of choosing two dimes.
= 18/40 x 17/39
= 306 / 1560
= 0.196
Thus,
P(both dimes) = 0.196

Apples cost four times as much as oranges per pound. Apples are $2.80 per pound. How much do oranges cost per pound? *
$11.20
$1.20
$0.70
$1.70
Step-by-step explanation:
Apples cost four times as much as oranges per pound.
If the cost of orange =x
then, cost of apples =4x
But,
the costs of apples =2.80$
So,4x=2.80
[tex]\tt{ x=\dfrac{2.80}{4} }[/tex] ⠀
[tex]\tt{ x=0.70\$ }[/tex] ⠀
so,oranges costs for per pound =0.70$

Step-by-step explanation:
ABCD is a trapezium AD and BC are parallel
Part (a)
Answer: 12.1-----------------------
Work Shown:
We'll apply the sine rule since we have a known opposite side of AB = 10 and an unknown hypotenuse we want to find BD.
Focus on triangle ABD
sin(angle) = opposite/hypotenuse
sin(D) = AB/BD
sin(56) = 10/x
x*sin(56) = 10
x = 10/sin(56)
x = 12.062179
x = 12.1
Make sure your calculator is in degree mode.
===================================================
Part (b)
Answer: 15.1-----------------------
Work Shown:
Draw an xy coordinate grid.
Place point A at the origin (0,0).
Point B is 10 units above this, so B is at (0,10).
Point C is at (18,10) since we move 18 units to the right of B.
Point D is at approximately (6.745085, 0). The 6.745085 is from solving tan(56) = 10/x for x.
Refer to the diagram below.
Apply the distance formula for the points C and D.
[tex]C = (x_1,y_1) = (18,10)\\\\D = (x_2,y_2) \approx (6.745085,10)\\\\[/tex]
[tex]d = \text{ distance from C to D}\\\\d = \sqrt{ (x_1-x_2)^2+(y_1-y_2)^2}\\\\d \approx \sqrt{ (18-6.745085)^2+(10-0)^2}\\\\d \approx \sqrt{ 226.673112 }\\\\d \approx 15.055667\\\\d \approx 15.1\\\\[/tex]

What is a quadrilateral?Any closed figure made by 4 line segments joined end to end in series is called a quadrilateral.
Given ABCD is a trapezium AD and BC are parallel
we have a known opposite side of AB = 10 and an unknown hypotenuse we want to find BD.
on triangle ABD
sin(angle) = opposite/hypotenuse
sin(D) = AB/BD
sin(56) = 10/x
xsin(56) = 10
x = 10/sin(56)
x = 12.062179
x = 12.1 degree
Let xy coordinate grid. Place point A at the origin (0,0).
Point B is 10 units above this, B is at (0,10).
Point C is at (18,10) since we move 18 units to the right of B.
Point D is at approximately (6.745085, 0).
The 6.745085 solving tan(56) = 10/x for x.
Apply the distance formula for the points C and D.
D = √(18 - 6.745085)² + (10 -0)²
D = 15.1

I got a 12 discount on a pair of jeans and a 25% discount on a t-shirt the original price of the jeans was $100 and thatof the T-shirt $50, how much did i pay for both items? (NEED EQUATION AND WORK)
Answer:
$125.50
but I'm not sure
Step-by-step explanation:
100÷100=1
1×12=12
100-12=88
jeans with discount = $88
50÷100=0.5
0.5×25=12.50
5000-1250=3750
t-shirt with discount = $37.50
3750+8800=12550
Answer:
125.5
Step-by-step explanation:
100 x .12= 12
100-12=88
50 x .25 = 12.5
50-12.5 = 37.5
88 + 37.5 = 125.5
80% of what number is 190
Answer: I would have to say 237.5
(152 is 80% of 190)
Step-by-step explanation:
If 190 is 80% of a number then you need to reverse the process, .8 * 190 = 80% OF 190 but 190 / .8 = 237.5 which means that 190 is 80% of 237.5

hi I need help is this true or false?
Answer:
B
Step-by-step explanation:
Please help me! And get marked as brainlist!
Answer:
Step-by-step explanation:
a) area of the rectangle = length × breadth
Therefore area should be = 12cm × 6cm
Which should give you the answer 72centimetre squared.
b) area of triangle A = 1/2 × b × h
So that is 1/2 × 3 × 6
Which is 18 centimetres × 1/2
Which is 9 centimetres squared
c) area of triangle B = 1/2 × b × h
So 1/2×3×6=18
Now 1/2×18 should give you 9 centimetres squared
d) therefore the area of the parallelogram = 72+9+9=90 centimetres squared
Therefore the area of the parallelogram is 90 centimetres squared

Answer:
a) ∠DAE = 33°; ∠ABD = 57°
b) ∠CEB = 90°
c) ∠ABE = 22°
d) ∠ADE = 15°
Step-by-step explanation:
The diagonals of a rhombus meet at right angles. Each bisects the corner angles at its ends. Adjacent angles are supplementary, opposite angles are congruent, and each diagonal creates two isosceles triangles.
a) ∠DAE = 90° - ∠ADE = 90° -57°
∠DAE = 33°
∠ADE = ∠ABD = 57°
__
b) ∠CEB = 90° . . . . . the diagonals meet at right angles
__
c) ∠ABE = 44°/2
∠ABE = 22°
__
d) ∠ADE = 90° -(1/2)∠DAB = 90° -150°/2
∠ADE = 15°
