Answer=
D
Step-by-step explanation
because of the dot/line at the top of the number it means it is a continuous same number
for example, 0.3 with a dot/line on top means it is 0.333333...
so 0.55...+0.33...=0.88...
and as it is a decimal that is in the range of 1-100 its like a percentage so it is 88/100
Answer:
20*x
Step-by-step explanation:
alright so lets start with how many cents are in a dollar
100 cents per dollar
we need to find 20 pounds so we can use an equation i made
lets say it's 22c per pound
20*x=$
lets try plugging in 22
20*.22=$4.20
1(6p-9) because 3(2p-3)=6p-9 1(6p-9)=6p-9 too
Answer:
10.8 m²
Step-by-step explanation:
To find area, we do 3.14*r^2
since diameter = 2 radius divide each by 2
2 and 0.75
A outer= 3.14*2^2
3.14*4
12.56 m²
A inner = 3.14*0.75^2
≈1.8 m²
to find the shaded area subtract the outer from the inner
12.56-1.8=10.76
which rounds up to
10.8 m²
If we use π then we get
about
12.57
and
1.77
subtract to get
10.8 m²
Answer: The width is 7 meters. The length is 10 meters.
Step-by-step explanation: Area = Length × width
Length is 2w - 4
Substitute that value for length, then solve for w.
70 = w(2w - 4)
70 = 2w² - 4w reorganize to quadratic equation form
2w² - 4w -70 = 0 These are All even numbers; factor out 2 (divide all by 2)
w² - 2w - 35 = 0 factor this
(w - 7)(w + 5) set each factor = 0 and calculate the value of w.
w+5=0 w= -5 (disregard this one because dimensions of real rectangles can't be negative)
w - 7 = 0 w = 7 <u>The width is 7</u>
Substitute into the original expressions to get the value of Length.
2(7) -4 = L 14 - 4 = L The<u> Length is 10.</u>
Check by substituting into the original equation:
w × 2w -4 = 70
7 × 2(7) -4 = 70
7 × 10 = 70 TRUE!
w
