Given the ratio of 1:8, which totals 9 parts,
we calculate the value of EACH part by dividing $117 by 9.
117/9 = 13
Sophia receives 1 part, resulting in her share of $13.
If one were to determine Isabella's share, it would be calculated as 13*8 = $104,
or alternatively, 117 - 13 = $104.
Therefore, in monetary terms, the ratio is $13:$104.

Two fathers and two sons own 21 horses. They are moving to different parts of the country and want to divide the horses evenly a
tester [12383]
They cannot possess the same number of horses; let me clarify. If you divide 21 horses among four individuals, you would perform 21/4, yielding 5.25, implying that fractional horses are unfeasible. Therefore, at least one individual must have 6 horses instead of 5. Possibly, this is what your instructor wants you to understand. For an even distribution, they could sell one horse, making it 20, so each would then have 5 horses. Alternatively, they might share the extra horse to rotate its usage.

Another project on Kickstarter for an iPad stylus raised 1,253% of their goal, raising a total of $313,490 from 7,511 supporters
Svet_ta [12734]

Answer:

The initial goal was $25019.154.

Step by step Explanation:

Assuming the original goal is denoted as x.

As stated

Another Kickstarter initiative for an iPad stylus secured 1,253% of its target, accumulating a total of $313,490.

1253% can be expressed as a decimal.

= \frac{1253}{100}

= 12.53

Thus, the equation is rearranged to

12.53 × x = 313490

12.53x = 313490

x = \frac{313490}{12.53}

x = $ 25019.154

This means the initial goal stands at $25019.154.

James has a desk job and would like to become more fit, so he purchases a tread walker and a standing desk which will allow him
Inessa [12570]

Answer:

The answer is

-0.245 \pm2.160(0.205)

Step-by-step explanation:

After operating under these conditions for a period of 6 months, he selects a simple random sample of 15 days. He logs the hours he walked each day as tracked by his fitness monitor, alongside his recorded billable hours from a work application on his computer.

The calculated slope is -0.245

The number of samples is n = 15

The standard error is 0.205

The confidence level is 95

The significance level is (100 - 95)% = 0.05

The degrees of freedom is n - 2 = 15 - 2 = 13

Critical Value = 2.16 = [using excel = TINV (0.05, 13)]

Marginal Error = Critical Value * standard error

= 2.16 * 0.205

= 0.4428

-0.245 \pm2.160(0.205)

Points A and B are midpoints of the sides of triangle QRS. Triangle Q R S is cut by line segment A B. Point A is the midpoint of
tester [12383]

Result: 4m

Detailed explanation:

Important note: midpoints split a line into equal halves.

To find the length of SA;

We observe the larger triangle QRS, which includes

Two midpoints:

A located on line QS, QA = 4m;

and B on line RS where RB = 3m

Based on the midpoint definition:

QS = QA + AS

where QA = AS

QS = 2QA = 2AS

Hence,

QA = QS

4m = 4m
