A road crew uses the triangles shown in the diagram to
measure the width of a sinkhole across a highway from a safe
distance away. How wide is the sinkhole?
Answer:
18 ft
Step-by-step explanation:
Both triangles shown are congruent.
By the concept of transversal lines and vertically opposite angles, we conclude that the width of the sinkhole is 18 feet.
What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
We know when a transversal intersects a parallel line vertically opposite angles are equal and we also know that sides opposite to similar angles have the same length.
∴ The width of the sinkhole is also 18 feet.

Answer:
A fraction is not a whole number but a number in between the whole number .
Step-by-step explanation:
It is a part of a whole. Also, a fraction has two parts of a numerator and a denominator. When the numerator and the denominator can no longer be reduced to any smaller number separately, we get the fraction in its simplest form.

so that means x = 5 and y = 3
The relation ((6, 8), (7, 10), (7, 12), (8, 16),
(10, 16)} is not a function. Which x-value has
more than one y-value associated with it?
Record your answer on the grid provided.
Answer:
x = 7 is repeated twice.
Hence, there is NO MORE unique input. We can not have repeated inputs.
Thus, the relation is NOT a function.
Step-by-step explanation:
Given the relation
{(6, 8), (7, 10), (7, 12), (8, 16), (10, 16)}We know that a relation is a function that has only one output for any unique input.
As the inputs or x-values of the relations are:
at x = 6, y = 8
at x = 7, y = 10
at x = 7, y = 12
at x = 8, y = 16
at x = 10, y = 16
If we closely observe, we can check that there is a repetition of x values.
i.e. x = 7 is repeated twice.
Hence, there is NO MORE unique input. We can not have repeated inputs.
Thus, the relation is NOT a function.

Answer:
t ≤ 12/23
Step-by-step explanation:
-48t + 2 ≤ -71t + 14
You would need to get all the numbers on one side and all the variables on the other side.
-48t + 2 -2 ≤ -71t + 14 -2 → -48t ≤ -71t + 12
-48t + 71t ≤ -71t + 71t + 12 → 23t ≤ 12
23t ÷ 23 ≤ 12 ÷ 23 → t ≤ 12/23

Determine the relationship between the given linear functions:
Line A: 4y - 12x = 20
Line B: 3y = -x + 2
9514 1404 393
Answer:
the lines are perpendicular
Step-by-step explanation:
When both equations are written in standard form, they are ...
y -3x = 5
3y +x = 2
The coefficients in one of these equations are swapped, and one is negated, relative to the coefficients in the other equation. This means the lines are perpendicular (their slopes are opposite reciprocals).
A graph confirms this relationship.

What is the surface area of the right prism given below?
O A. 298 units2
OB. 840 units2
O C. 480 units2
O D. 420 units2
Answer:
480 units^2
Step-by-step explanation:
5 * 12 = 60
13 * 14 = 182
12 *14 = 168
5 * 14 = 70
480
The surface area of the given prism will be 480 square units so the correct answer is option C.
What is surface area?The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.
The triangular prism is having 6 surfaces so the surface area will be the sum of the area of all the sides of the prism.
The area of all the sides of the prism will be calculated as follows:-
5 x 12 = 60
13 x 14 = 182
12 x 14 = 168
5 x 14 = 70
The total surface area of the prims will be:-
SA of prism = 60 + 182 + 168 + 70 = 480 square units
Therefore the surface area of the given prism will be 480 square units so the correct answer is option C.

The number of cupcakes sold at the bakery dropped 25% this month and they sold only 240 cupcakes this month. How many cupcakes did they sell last month?
Answer:
300 cupcakes
Step-by-step explanation:
Okay, the first step is finding 25% of 240, we do this by multiplying .25 by 240. This gets us 60. Then, to get 125% of 240 (since sales dropped 25%), we add 240 and 60, this gets us 300. 300 cupcakes were sold. Another way to do this is 1.25x240. I wanted to explain it more thoroughly, though.

. You can buy 2 ice cream cones for $3.00 or 4 ice cream cones for $7.00. Which is the better buy? *Hint: First write the rate as a fraction. Remember, money always goes in the numerator. Now find the unit rate by dividing the numerator by the denominator.
Answer:
The better buy is 2 ice cream cones for $3.00
Step-by-step explanation:
Step one:
given
You can buy 2 ice cream cones for $3.00
let us solve for the unit cost
3/2= $1.5 per ice cream cone
Step two:
You can buy 4 ice cream cones for $7.00
let us solve for the unit cost
7/4= $1.75 per ice cream cone
The better buy is 2 ice cream cones for $3.00 because a cone is $0.25 less expensive than 4 ice cream cones for $7.00.
