Audrina drank 4 5 liter of water Monday before going jogging. She drank 2 3 liter of water after her jog. How much water did Aud

hodyreva [135]

Answer:

$1\frac{7}{15}$

Step-by-step explanation:

The computation of the water did Audrina drink altogether is as follows:

$= \frac{4}{5} + \frac{2}{3}\\\\= \frac{12 + 10}{15} \\\\= \frac{22}{15}$

Now in a mixed fraction, it would be

$1\frac{7}{15}$

Hence, the water did Audrina drink altogether is $1\frac{7}{15}$

What are the missing measures for E and J??? Are the triangles similar? Yes or no?

yawa3891 [41]

Answer:

Step-by-step explanation:

To tell whether two triangles are similar or not, we can compare their side lengths or angle measures

in this case, only angle measure are given so will compare those:

m<F = m<I but this is not enough, we need to compare other angles as well

m<H is not equal to m<G

The sum of interior angles in a triangle is equal to 180

so the measure of angle J

100+55+J = 180

J = 25

The measure of angle E

100+35+E = 180

E = 45

Now, neither of these angles are equal to each other so we can conclude that these triangles are not similar.

What is the value of the sum? - 3/8+ 5/10 -11/16 -1/16 1/16 1/4 -1/4

mafiozo [28]

First, you must convert the decimals to have the same denominator.

Find the least common multiple of both fractions' denominators:

Multiples of 8: {8,16,24,32,40}
Multiples of 10: {10,20,30,40}

The least common multiple of 8 and 10 is 40.

Multiply the fractions by a number that will make their denominator 40:

$- \frac{3}{8} \times \frac{5}{5} = - \frac{15}{40}$
$\frac{5}{10} \times \frac{4}{4} = \frac{20}{40}$

Now you can add these fractions together:

$-\frac{15}{40} + \frac{20}{40} = \frac{5}{40}$

Simplify this fraction:

$\frac{5}{40} \div \frac{5}{5} = \frac{1}{8}$

The answer should be 1/8.

Azaria invests $6670 in a savings account with a fixed annual interest rate 3% compounded monthly. What

Sholpan [36]

Answer: 7983.65

Step-by-step explanation:

Equation:

A = P ( 1 + r/n)^nt

R : r/100 : 3% : 0.0.3

A = 6670( 1 + ( 0.03/12) : ^12(16)

A: 6670( 1 + 0.0025)^(74)

Put this on calculator

A = 7983.65

Hope this help.
