Two cities Asheville and Boulder are 2.5 inches apart on a map. A third city well spring is located exactly halfway between Asheville and Boulder. If the scale is 0.5 inches = 15 miles find the actual distance from wellspring to Boulder
Answer:
75miles
Step-by-step explanation:
Let A be the location of Asheville, B be the location of Boulder and W be the location of wellspring.
If well spring is located exactly halfway between Asheville and Boulder, then;
AW + WB = AB
If Asheville and Boulder are 2.5 inches apart on a map, then AB = 2.5 inches
The actual distance from wellspring to Boulder is WB
Since W is the midpoint of A and B, then AW = WB. The equation becomes;
WB + WB = AB
2WB = AB
WB = AB.2
WB = 2.5/2
WB = 1.25 inches
Hence the distance from wellspring to Boulder is 1.25inches.
Since 0.5 inches = 15 miles on the map,
1.25inches = x
Cross multiply;
0.5x = 15 * 1.25
0.5x = 18.75
x = 18.75/1.25
x = 75miles
Hence the actual distance from wellspring to Boulder is 75miles

Answer:
The shopper should but the 6 pcs pack because its cheaper.
Step-by-step explanation:
6-pcs pack = $2.10
hot dogs needed = 48
number of 6 pcs = 48 divided 6 = 8
total cost = $2.10 x 6 = $16.80
8 pcs pack = $3.12
hot dogs needed = 48
number of 8 pcs packs = 48 divided 8= 6
total cost = $3.12 x 6 =$18.72

Savion uses the escalator in the shopping mall to get to the ground floor from the underground garage located at (8,-5). Which of the following coordinates correspond to the location of the ground floor when undergoing a translation of 5 steps to the right and 11 steps upwards?
Answer choices:
(8,-5)
(13,6)
(13, -16)
(3,16)
Answer: the second option

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.

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:
C. a=12ft, b=12ft
Step-by-step explanation:
This is a 45*-45*-90* triangle
"a" and "b" are the same
and the hypotenuse (which is 12 square roots of 2) is square root of 2 times as long as each leg.
so the answer must be:
a = 12ft, b = 12ft

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.
