Answer:
[tex] \frac{160}{3} [/tex]
Step-by-step explanation:
Step 1: A discount of
[tex] \frac{1}{3} [/tex]
means that the current price is two thirds of the original cost.
Step 2: The total cost is
[tex]80 \times \frac{2}{3} = \frac{160}{3} [/tex]
and the answer follows.
Solution:
Note that:
80 x (3/3 - 1/3) = Discounted costSimplify the expression.
80 x (3/3 - 1/3)=> 80 x (2/3)=> 160/3 = $53.33 = Discounted costLynn will pay $53.33.

Find the area of this figure round your answer to the nearest hundredth use 3.142 approximate
Answer:
49ft²
Step-by-step explanation:
step 1: calculate area of triangle
Area = 1/2 × b × h
= 1/2 × 6 × 8
= 24 ft
step 2: calculate area of semi circle
Area = 1/2 × (π.r²)
= 1/2 × (3.142 × 4²)
= 25.136 ft
rounded off = 25
step 3: add the 2 areas
24 + 25
= 49 ft²

A rectangle has a length of
( x + 5 ) cm and a width of
( 2x - 3 ) cm. Its perimeter is 46 cm. Calculate the value of x
2(x+5 +2x-3) = 46
2( 3x+2) = 46
3x+2 = 46/2
3x = 23-2
x = 21 /3
x = 8
Answer:
X = 7
Step-by-step explanation:
2(x+5 +2x-3) = 46
2( 3x+2) = 46
3x+2 = 46/2
3x = 23-2
x = 21 /3
x = 7
Solve the Indices finding the value of x and y 7^2y×3^x=63.
Answer:
y = 1/2
x = 2
Step-by-step explanation:
7^2y × 3^x = 7 × 9
7^2y × 3^x = 7^1 × 3²
7^2y = 7^1 so y = 1/2
3^x = 3² so x = 2

Identical lines through the sides of a triangle indicate that the sides are:.
When the sides are the same then the triangles are congruent.
Identical lines through the sides of a triangle indicate that the sides are congruent.
What is the congruent triangle?Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.
Congruent triangles are two triangles that are identical in terms of size and shape. One of two congruent triangles remains congruent even if it is rotated, flipped, or turned. Two triangles must have the same sides in order for them to have the same angles and, as a result, to be congruent.
Thus, identical lines through the sides of a triangle indicate that the sides are congruent.

At a basketball game, a vender sold a combined total of 172 sodas and hot dogs. The number of hot dogs sold was 46 less than the number of sodas sold. Find the number of sodas sold and the number of hot dogs sold.
Answer:
Let x = # of hot dogs sold
Let x + 31 = # of sodas sold
For the total, do: x + x + 31 = 173
2x + 31 = 173
-31 -31
2x = 142
Divide out both sides by 2; to get: x - 71
That gives us 71 hot dogs; and 71 + 31 = 102 sodas
To test this: 71 + 71 + 31 = 173
173 = 173 [Check]

Answer:
∠ ABC = 79°
Step-by-step explanation:
the measure of the inscribed angle ABC is half the measure of its intercepted arc AC
the sum of the arcs on the circle = 360° then
arc AC = 360° - 94° - 108° = 360° - 202° = 158° , then
∠ ABC = [tex]\frac{1}{2}[/tex] × 158° = 79°

These lines are...
1.Perpendicular
2.Parallel
3.Neither
The slopes -2/3 and 3/2 multiply to -1, which is sufficient info that the lines are perpendicular. Perpendicular slopes always multiply to -1 assuming neither line is vertical nor horizontal.
Note how -2/3 is the negative reciprocal of 3/2, and vice versa.
Answer:
perpendicular
perpendicular lines have slopes that are negative reciprocals of one another. if a slope of a line was 5, then the slope of a line perpendicular to it would be -1/5, for example.

In the straightaways, each lane is a rectangle. What is the area and perimeter of each
lane in the straightaways?
The area of the lane is 50 in² and its perimeter is 30 in.
What is an areaArea is the amount of space occupied by a two dimensional object or figure. For a rectangle:
Area = length * width
Let the length of the lane be 10 in and the width be 5 in, hence:
Area = 10 * 5 = 50 in²
Perimeter = 2(length + width) = 2(10 + 5) = 30 in
The area of the lane is 50 in² and its perimeter is 30 in.

10. A coordinator at a local fundraiser has 14 volunteers to help out. There will be 3 volunteers working at the entrance door, 4 volunteers helping with the young children and 7 working at the tables with the fundraising activities.
a) In how many ways can the volunteers be assigned? [2]
b) Mary and Martha are new volunteers this year, so they should not be placed together. In how many ways can the volunteers be assigned so that Mary and Martha are not at the same station? [3]
The combination and permutations computed shows that the number of ways that the volunteers can be assigned is 120120.
How to calculate the combinationFrom the information given, the number of ways that the volunteers can be assigned will be:
= 14C3 × 11C4 × 7C7.
= (14 × 13 × 12)/6 × (11 × 10 × 9 × 8)/24
= 120120
Also, the number of ways that the volunteers can be assigned so that Mary and Martha are not at the same station will be:
= 12C1 × 11C4 × 7C7
= 12 × 330 × 1
= 3960
