A container weighs 23 2/5 pounds holds sports equipment. Of the equipment in the container 1/3 of the weight is baseball equipme

hram777 [196]

What we need to know is how much is 1/3 of 25 2/5.

We will be multiplying fraction by a fraction and for this, it's good to change mixed numbers into improper fractions:

25 2/5= $\frac{23*5+2}{5}= \frac{117}{5}$

and now we multiply it by 1/3:

$\frac{1}{3}\frac{117}{5}=\frac{39}{5}=7\frac{4}{5}$

and that's the answer: the basketball equipment weights 7 4/5 pounds.

andriy [413]

Answer:

Sue must score 94 on the final test to earn a B.

Step-by-step explanation:

There are five tests in total.

Sue's average on the first four tests is 84.

If after the final test, she scores X, she will have a B on average of five tests.

We have the following equation:

86 = (4 × 84 + X)/5

<=> X = 5 × 86 - 4 × 84

=> X = 94

6x2 +10x−1 discriminant

eimsori [14]

Answer:

$124$

Step-by-step explanation:

$6 {x}^{2} +10x−1$

The discriminant of a quadratic is the expression inside the radical of the quadratic formula.

${b}^{2} −4(ac)$

Substitute in the values of a, b, and c.

${10}^{2} −4(6 \times (−1))$

$100−4(6(−1)$

$100−4(−6)$

$100 + 24$

$124$

How do i solve each proportion?

natali 33 [55]

You have to cross multiply (multiply the numerator of the first by the denominator of the second and the numerator of the second by the denominator of the first).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[19]

$\frac{x+4}{3} = \frac{4}{10}$

$10x+40=12$

$10x = -28$

$x=-2.8$

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[21]

$\frac{4}{n+8} = \frac{10}{8}$

$32 = 8n + 64$

$8n = -32$

$n=-4$
