Since the bottom shape is a semi-circle, the 3yd is the radius making the triangle's area 7 x 3 / 2 = 10.5

The semi-circle's area is $\pi$ $3^{2}$ /2 = 14.14

Combined, you get an area of 10.5 + 14.14 = 24.64 $yd^{2}$

The question is asking me choose all of the numbers that are unit fractions, and here are my options, 14 <16 14 <16 510&lt

____ [38]

Answer:

$(d)$ $\frac{4}{8}>\frac{2}{6}$

Step-by-step explanation:

Given

$\frac{1}{4}$

$\frac{5}{10}$

$\frac{1}{2}>\frac{1}{3}$

$\frac{4}{8}>\frac{2}{6}$

$\frac{3}{5}>\frac{4}{5}$

Required

Select the unit fractions

If we are to go by what a unit fraction means: it means that the numerator of the fraction must be 1 and must be written as a single fraction i.e. $\frac{1}{2}$  and not as an inequality i.e.  $\frac{3}{5}>\frac{4}{5}$ 

Given the format of the question, what is required of the question is to select all correct inequality.

$(a)$ $\frac{1}{4}$

Convert to decimals

$0.25 < 0.167$ ---- This is not true because $0.25 > 0.167$

$(b)$ $\frac{5}{10}$

Convert to decimals

$0.5 < 0.5$ ---- This is not true because $0.5 = 0.5$

$(c)$ $\frac{1}{2}>\frac{1}{3}$

Convert to decimals

$0.5 > 0.33$ ---- This is true

$(d)$ $\frac{4}{8}>\frac{2}{6}$

Convert to decimals

$0.5 > 0.33$ ---- This is true

$(e)$ $\frac{3}{5}>\frac{4}{5}$

$0.6 > 0.8$ --- This is not true because $0.6 < 0.8$

So: the true inequality is:

$(d)$ $\frac{4}{8}>\frac{2}{6}$

Identify the 34th term of the arithmetic sequence 2, 7, 12

torisob [31]

The equation is AN=A1+D(N-1) A1 being the first number (2) D being the difference (in this case 5) and N being the nth term to find (34) so here you have AN=2+5(34-1) then AN=2+5(33). the answer here is 167.

One thousand dollars is invested in a savings account that pays 9% interest per year. The interest earned after the first year i

Ray Of Light [21]

In order to solve this problem, the first thing we are going to do is find out how much is 9% of 1000, since 9% is the interest per year. So 0.09 x 1000 and that would be 90. And since the interest earned is added to the account, the account will now have a total of $1090 which is now the new principal. Based on this new principal, we need to know the 9% of it again to know how much interest in earned in the following year. So that would be 0.09 x 1090 and the result is $98.10. Hope this answer helps.

ABC DEF. The area of ABC is given. Find the area of DEF

densk [106]

Answer: B

Step-by-step explanation:

The ratio of the areas of similar figures is the square of the scale factor.

Scale factor = image/preimage = 48/12 = 4.

So, the ratio of the areas is 16, and thus the area of DEF is (16)(90)=1440
