Answer:
x = 3, y = 10.
Step-by-step explanation:
The 2 triangles are similar so the corresponding sides are in the same ratio.
x/6 = 4/8
x/6 = 1/2
x = 6/2 = 3.
y/5 = 8/4 = 2
y = 5*2 = 10,
Perimeter = 2(l + w)
Thus,
102 = 2(l + w)
l = 6 + 2w
102 = 2( 6 + 2w + w)
102 = 12 + 4w +2 w
102 = 12 + 6w
90 = 6w
Thus, w = 15.
Length = 6 + 2w
= 6 + 30
= 36.
Thus, the length is 36 meters and width is 15 meters.
Answer:
-8
Step-by-step explanation:
-8x - 47 = 17
+47 +47
-8x = 64
Divide both sides by -8
x = -8
Answer:
2.970600004839 × 10^5
Step-by-step explanation:
First, we add up these 2 numbers.
297,060 + 0.0004839 = 297060.0004839
Then, we convert that into scientific notation.
297060.0004839 = 2.970600004839 × 10^5
Finally, we check if it's right.
10^5 = 100000
2.970600004839 * 100000 = 297060.0004839
Hope this helps.
Answer:
The answer is $4.30
Step-by-step explanation:
Firstly, you will need to find how much tax is added to each price.
16(0.07)=1.12 (Note I changed the percent into decimal)
20(0.07)=1.4 (Note that I again changed the percent into a decimal)
16+1.12=17.12
20+21.4
To find the difference means to subtract.
21.4-17.12=4.28
Rounded to the nearest cent is $4.30
