Answer:
$1470
Step-by-step explanation:
sneakers : boots
15 : 19
15 cost sneakers
------ = -------------------
19 570
using cross products
15 * 570 = 19 * sneakers
8550=19 * sneakers
divide by 19
8550/19 = sneakers
sneakers = 450
total cost = 2* sneakers + boot
total cost = 2 * 450 + 570
total cost = 900 + 570
total cost = 1470
Answer:
53/100
Step-by-step explanation:
7*(60+3)=7*60+7*3= 420+21=441
1) The triangles are congruent by SSS.
The two tick marks indicate two pairs of congruent sides; it is evident that the third side is congruent by the way the diagram is drawn - the bases of the triangles are together and appear to be the same length.
2) The triangles are congruent by SAS.
The two pairs of tick marks indicate congruent sides, and their included angles are congruent because they are vertical angles, and vertical angles are always congruent.
Get the distance between two acres.
2.5 - 2.4 = 0.1
Divide the diffence by 2
0.1 / 2 = 0.05 - Halfway between them.
Therefore, 0.05 must be taken from 2.5 acres. it must be added to 2.4 acres to get the exact area of the park.
2.5 - 0.05 = 2.45
2.4 + 0.04 = 2.45 acres
OR
Simply get the average of the two to get the area since it is exactly halfway between the two acres of land.
2.5 + 2.4 = 2.9 / 2 = 2.45 acres
