Answer:
557.8m²Step-by-step explanation:
2 opposite semicircle are same
diameter = 9m
radius = 4.5m --- (diameter = 1/2radius)
area of semicircle = 1/2 × π × radius²
= 1/2 × 3.14 × 4.5×4.5
= 31.79m²
2 semicircles area = 31.79 × 2
= 63.8m²
______________________________
______________________________
other 2 opposite semicircle are same
diameter = 20m
radius = 10m --- (diameter = 1/2radius)
area of semicircle = 1/2 × π × radius²
= 1/2 × 3.14 × 10×10
= 157m²
2 semicircles area = 157 × 2
= 314m²
______________________________
______________________________
length = 20m ----- ( given )
breadth = 9m ----- ( given )
area = length × breadth
= 20 × 9
= 180m²
______________________________
______________________________
AREA of whole figure = 63.8 + 314 + 180
= 557.8m²
14 club members have birthdays in summer. This is 20% of the birthdays in the club. How many club members are there? How do you do this, for kids?
Answer:
70 club members in all
Step-by-step explanation:
we know that 14 people is equal to 20%
we also know that to get 20% to 100% you multiply by 5
So, what I did was mmultiply 14 by 5 therefore bringing 14 (20%) to 70 (100%)
hope this makes sense. for other values you could just see what to multiply the percent by to get to 100 and multiply the known number by that value.
hope this helps <3
Answer:
70 members
Step-by-step explanation:
Whatever the % is, the answer on the right side of the equation must by 14
So 20% of some number = 14.
20/100 x = 14 Remember 20% = 20 / 100. Multiply by 100
20x = 14*100
20x = 1400 Divide by 20
x = 1400/20
x = 70
There are 70 members in the club.
Kids are done no differently.
The number of people who fulfill the condition goes on the right. The left contains the % and an unknown.

xy=80 solve log x- log y=1
Question: Solve for x and y in the equation.
xy=80 and log x - 2 log y =1
Answer:
x = 40, y = 2
Step-by-step explanation:
xy = 80.......................... Equation 1
logx-2logy = 1
logx-logy² = 1
Applying the laws of logarithm,
log(x/y²) = log10
x/y² = 10
x = 10y²......................... Equation 2
Substitute the value of x in therms of y equation 2 into equation 1
10y²(y) = 80
10y³ = 80
y³ = 8
y = [tex]\sqrt[3]{8}[/tex]
y = 2.
Substitute the value of y into equation 1
2x = 80
x = 80/2
x = 40
Therefore,
x = 40, y = 2

Tasha needs to eat no more than 1,800 calories per day. Each scoop of ice
cream contains 100 calories. How many scoops of ice cream can Tasha eat
for dessert tonight if she already consumed 1,450 calories today?
Answer:
3.5 or 3 1/2
Step-by-step explanation:
1,800-1,450=350
She has 350 calories left to consume 1,800 in total.
There are 3.5 100 calories in 300.
The awnser will be 3.5 or 3 1/2.
She can have 3 1/2 of ice cream.

a) In a simple random sample of 1000 faculty taken among all universities in a country, the number of papers published by the individual sampled faculty in the past year had a mean of 1.1 and an SD of 1.8. Does the Central Limit Theorem say that the distribution of the number of papers published by the individual sampled faculty in the past year is roughly normal
Answer:
According to the Central Limit theorem, the distribution is roughly normal
Step-by-step explanation:
The Central Limit Theorem states that for sample sizes above 30 and not withstanding population distribution's shape, the sampling distribution of the sample mean becomes more similar t hat of a normal distribution as the sample size increases;
The size of the sample = 1,000 >> 30
As the sample size approaches infinity, we have;
[tex]z=\dfrac{\bar{x}-\mu }{\dfrac{S.D.}{\sqrt{n}}}[/tex]
[tex]\overline x[/tex] = 1.5
S.D. = 1.8
n = 1000
Assume μ = 1, we get;
[tex]P(x > 1.1):z=\dfrac{1.1-1 }{\dfrac{1.8}{\sqrt{1000}}} = 1.7568[/tex]
P(z > 1.7568) = 1 - 0.96080 = 0.0392
Therefore, it is very likely that the mean of the population is not larger than the sample mean
Therefore, yes, the Central Limit Theorem say that the distribution of the number of papers published by the individual sampled faculty in the past year is roughly normal

Patty purchased rose bushes and geraniums for her yard. Patty spent $206 on 14
rose bushes and 12 geraniums. The price of a geranium is $5 less than twice the
cost of a rose bush. What is the cost of one rose bush?
9514 1404 393
Answer:
$7
Step-by-step explanation:
Let r and g represent the costs of a rose bush and a geranium, respectively. The given relations are ...
14r +12g = 206
g = 2r -5
Using the second equation to substitute for g in the first equation, we have ...
14r +12(2r -5) = 206
38r -60 = 206
38r = 266
r = 266/38 = 7
The cost of one rose bush is $7.
