Answer:
10%
Step-by-step explanation:
To find the percentage, ask yourself, how much is 2000 of the original value which is 20350. This can be solved by the following equation.
2000/20350=
The answer is approximately 0.09828. Then, convert this to a percent. 9.828%. Then, round it to the nearest percent. The answer is 10%
Answer:
6 because it is the only number that occurs more then once
Answer:
The value of Y is 24 km and distance from A to C to B is AC+Y=18+24=42 km
Step-by-step explanation:
Given that A highway between points A and B has been closed for repairs. An alternative route between there two locations is to travel between A and C and then from C to B. we have to find the value of Y and the total distance from A to C to B. Let AB=Z
In ΔBCD and ΔABD
∠BCD=∠ABD (∵each 90°)
∠D=∠D (∵common)
By AA similarity, ΔBCD~ΔABD
∴ their corresponding sides are proportional

Comparing last two terms, we get

⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Hence, the roots are X=32, -50
X=-50 not possible as distance can never negative.
Hence, X=32 km
By applying Pythagoras theorem in ΔBCD we get


⇒ 
⇒ 
Hence, the value of Y is 24 km and the distance from A to C to B is AC+Y=18+24=42 km
Answer:
68
Step-by-step explanation:
Let x be the original price
The original price times the percent = 17
x*25% = 17
Change to decimal form
x*.25 = 17
Divide each side by .25
.25x/.25=17/.25
x =68
Answer:
C: 4
Step-by-step explanation:
To find the degree of the polynomial, put the exponents in order from largest to smallest
5x^4-3x^2+2x+1
The degree is the largest power, or in this case, the largest power is 4, so the degree is 4
