The sum of three numbers is 50. If the third number is one-third the second number and the first number exceeds the second numbe

galina1969 [7]

Answer:

second number= X

first number = X+8

third number X/3

sum of three numbers is 50.

X+X+8+X/3=50

2x+x/3=50-8

(6x+x) / 3 =42

7x =42*3

X =42*3/7

=18

Second number=18

third number= 18/3=6

first number=18+8=26

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:

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

Given that lim x→1 (5x − 3) = 2, illustrate definition 2 by finding values of δ that correspond to ε = 0.1, ε = 0.05, and ε = 0.

kow [346]

$\displaystyle\lim_{x\to1}(5x-3)=2$

is to say that for any $\varepsilon>0$ , we can find $\delta>0$ such that $0$ implies $|(5x-3)-2|$ .

To that end, we have

$|(5x-3)-2|=|5x-5|=5|x-1|$

which means that if $\varepsilon=0.1$ is given, then we can choose $\delta=\dfrac{0.1}5=0.02$ ; if $\varepsilon=0.05$ , then $\delta=\dfrac{0.05}5=0.01$ ; if $\varepsilon=0.01$ , then $\delta=\dfrac{0.01}5=0.002$ .

38. The volume of a cylinder is 97 ft3. If the dimensions are doubled, what will be the new volume?

asambeis [7]

Volume is cubed. If the dimensions are doubled, cube the scale factor:

2^3 = 8

The volume will increase by a scale of 8.

The new volume would be 97 x 8 = 776 ft^3
