Answer:
Step-by-step explanation:
1/10 + 2.5/10 = 3.5/10 of an hour to make one bracelet. Then change to 20ths so the numerator is a whole number.
Divide your time available by the time it takes to make one.

What is the area of triangle ABC? a \large 6\sqrt{3} square units b \large 18\sqrt{3} square units c \large 36\sqrt{3} square units d \large 72\sqrt{3} square units
question isn't clear but I believe you are asking for the area of triangle ABC given sides a, b, c
We use the example question:
Find the area (in square units) of the triangle described.
a = 49mm, b = 33mm, c = 18mm
Answer and explanation:
We apply Heron's formula to solve the area of a triangle given the sides of the triangle a, b, c
A= √s(s-a)(s-b)(s-c)
Where A = area of triangle in square units
s= semiperimeter(a+b+c/2) of a triangle
a, b, c= lengths of the sides of the triangle
Therefore area of triangle =√50(50-49)(50-33)(50-18)
= √27200
=164.92mm²
Which rule explains why these triangles are congruent?
Answer:
ASA prove it's congruent
as 2 angles are equal and a side between of them is same for both triangles.
in 1990 Jamaica's population of 2,466,000 was expected to grow exponentially by 1.1% each year. what is the range of the exponential function that decribes this growth
Answer:
Initial population is 2,466,000 ( p0 )
Growth is 1.1% each year ( r=1.1
p(t)=p0(1+r)t
After 30 years, the population of Jamaica should be 3.42 million by that calculation, but it is only 2.95 million, so apparently that growth rate was a little high, or wasn’t sustained.

O (-3,-4)
O (-5,-3)
O (-4,-3)
O (-3,-5)
Answer:
5x-4+-20+ -3=-23
Step-by-step explanation:
5x-3= -15 + -4 = 11
5x-5=-25+-3=22
5x-4=-20+-3=-23
5x-3= -15+ -5= -20

Ratnam hired a car from a car renting agency which charges a flat amount of Rs x for travelling up to 40 kilometres and Rs. y per km for every kilometre travelled thereafter. How much should Ratnam pay the agency for a journey of 50 kilometres in Rs. ?
Answer:
Rs. X + Rs. 10y
Step-by-step explanation:
Charge for 40 km travel = Rs. x per km
Charge for every additional km traveled = Rs. y
Amount paid for 50 km
Fixed charge for 40km = Rs. X
Additional km = 50 - 40 = 10 kilometer
Total charge :
Rs. X + Rs. 10y

help me answer question 8a and b, and I’ll give u 10 points lol
Answer:
Step-by-step explanation:
Find h when v = 20 and r = 3
Putting values in the formula
20 = (3.14)(3)2h
20 = (3.14)(9)h
20 = 28.26h
20/28.26 = h
R when v = 100 and h = 5
100 = (3.14)r2(5)
100/5 = 3.14r2
20 = 3.14r2
20/3.14 = r2
6.36 = r2
Square root on both sides
2.52 = r

-7 - 3x = 1x + 4(2 + x)
Step 2: Solve for x
Distribute 4: -7 - 3x = x + 8 + 4xCombine like terms: -7 - 3x = 5x + 8[Addition Property of Equality] Add 3x on both sides: -7 = 8x + 8[Subtraction Property of Equality] Subtract 8 on both sides: -15 = 8x[Division Property of Equality] Divide 8 on both sides: -15/8 = xRewrite/Rearrange: x = -15/8Jason bought 3 shirts that each cost the same. He had a coupon for $10 dollars off and he spent $65 altogether. Which equation can be used to find the cost of each shirt?
Answer: $18.33

7 times 0.04 equal 7 times 4 times ?
Answer:
Solution
1 Cancel 77 on both sides
x\times 0.04=x\times 4xx×0.04=x×4x
2 Regroup terms
0.04x=x\times 4x0.04x=x×4x
3 Use Product Rule: {x}^{a}{x}^{b}={x}^{a+b}x

Answer:
100
Step-by-step explanation:
Isosceles triangle have 2 equal angles. Therefore the second angle in the triangle will also be 25.
Since the sum of angles in a triangle is 180.
180-(25x2) will give you the last angle in one of the triangles.
The other angle is identical so the angle at the top of the other triangle will also be 130.
The sum of angles in a circle is 360.
Therefore, angle x = 360-(130x2)
X= 100
