Answer:
The parts are 63 and 81
Step-by-step explanation:
Ratios
We have to split the number 144 into two parts such that they are in the ratio 7:9.
Let's call
x = one of the parts
144 - x = the other part
It must be satisfied:
[tex]\displaystyle \frac{x}{144-x}=\frac{7}{9}[/tex]
Cross-multiplying the denominators:
9x = 7(144 - x)
Operating:
9x = 1008 - 7x
Adding 7x:
16x = 1008
Dividing by 16:
[tex]x = \frac{1008}{16}=63[/tex]
First part: x=63
Second part: 144-63=81
The parts are 63 and 81

Answer:
$568.38
Step-by-step explanation:
Michaels starts the day with $782.88 in his account.
Then he uses $55 from his debit cars to pay for car repairs. Subtract 55 from 782.88 to get $727.88 in the account after the repairs.
After that, he uses $89.50 for a clothing purchase. Subtract $89 from $727.88 to get 638.88, then subtract another 50 cents to get $638.38 after the clothing purchase.
Lastly, he withdraws $70 from his account. Subtract 70 from $638.38 to get a final answer of $568.38 at the end of the day.

What is the positive radian measure of the smaller angle formed by the hands of a
clock at 5 o'clock?
Answer:
the required positive radian measure of the smaller angle is 5π/6 radians or 2.618 radians
Step-by-step explanation:
Given the data in the question;
smaller angle formed by the hands of a clock at 5 o'clock
{at 5 o'clock, two angles are form; 150° and 210°}
hence, the smaller angle is 150°
so, smaller angle = 150° × π/180°
smaller angle = 150°π/180°
smaller angle = 5π/6 radians or 2.618 radians
Therefore, the required positive radian measure of the smaller angle is 5π/6 radians or 2.618 radians
The positive radian measure of the angle formed by the hands of the clock at 5 o'clock is [tex]\frac{5\pi}{6}\text{ radians}[/tex]
In one minute, the long hand makes a full turn equivalent to [tex]2\pi[/tex] radians.
At 1 o'clock, the smaller angle formed by the hands of the clock is
[tex]\dfrac{2\pi\text{ rads}}{12}=\dfrac{\pi}{6}\text{ rads}[/tex]
At 5 o'clock, the smaller angle is five times the one we have when the time is 1 o'clock. That is
[tex]\dfrac{\pi}{6}\text{ radians}\times 5=\dfrac{5\pi}{6}\text{ radians}[/tex]

n Brad's golf bag, he has 4 times more white golf balls than yellow golf balls. He has 24 white golf balls in his bag.
Which equation can be used to find how many yellow golf balls, y, Brad has in his bag?
A.
24y = 4
B.
4y = 24
C.
4 + y = 24
D.
24 + y = 4
Answer:
4y = 24
Step-by-step explanation:
Given:
4 x Number of yellow balls = Number of white balls
Number of white balls = 24
Number of yellow balls = y
Computation:
4 x Number of yellow balls = Number of white balls
4 x y = 24
4y = 24
Number of yellow balls = y = 6 balls

Which statement about the data is true?
A. The median is 4, and the interquartile range is 10
B. The median is 4, and the interquartile range is 5
C. The median is 5, and the interquartile range is 10
D. The median is 5, and the interquartile range is 5
Answer:
Letter B is the correct answer. Median is 4 and IQR is 5.
Step-by-step explanation:
The median is 4 and the interquartile range is 6. The correct option is B.
What is an interquartile range?The interquartile range is a measurement of a data set's "middle fifty." A range is a measurement of where a set's beginning and end are located.
The median is the middlemost value of the numbers arranged in ascending orders. If the number of the data is an odd number so the median will be a middle number if the number of the data is even then the median is the mean of the middle two numbers.
The data is given below:-
0,0,0,1,1,3,3,3,4,4,4,6,6,7,7,7,8,8,9,10
Median = (4 + 4) / 2 = 4
The interquartile range is calculated as:-
0,0,0,1,1,3,3,3,4, | 4,4 |, 6,6,7,7,7,8,8,9,10
Lower range upper range
IQR = 7 - 1 = 6
Therefore, the median is 4 and the interquartile range is 6. The correct option is B.

If labor costs were $3,000,000 last year and $2,700,000 this year, what percentage decrease was achieved?
Answer:10%
Step-by-step explanation:
The percentage decrease achieved would be 10 % when labor costs were $3,000,000 last year and $2,700,000 this year.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If Saima obtained a score of 57% on her exam, that corresponds to 67 out of 100. It is expressed as 57/100 in fractional form and as 57:100 in ratio form.
The labor costs were $3,000,000 last year and $2,700,000 this year which is given in the question.
We have to determine the percentage decrease that was achieved.
As per the given information, the required evaluation would be as:
⇒ ($3,000,000 - $2,700,000)/3,000,000 × 100
⇒ 3,000,00/3,000,000 × 100
⇒ 0.10 × 100
⇒ 10 %
Therefore, the percentage decrease achieved would be 10 %.

Year 2 = new price = $96.25
The inflation rate is the difference in price between two Given period :
Inflation rate :
(Change in price / old price) * 100%
((New price - old price) / old price) * 100%
((96.25 - 95) / 96) * 100%
= (1.25 / 95) * 100%

Midpoint question......
Answer:
24; 12; 35
Step-by-step explanation:
Midsegments are 1/2 or their parallel line, so:
SU*2=QR
QR=24
Since QT is half of QR because point T is the midpoint of that line:
SU*1=QT
QT= 12
If PR=70, then ST is half of that:
70/2=35

A trade school would like to measure the long-term success of their graduates after they leave the school. The school
emails a survey requesting information from graduates about their work experience. One question asks graduates to
share their annual salar), and the results of the question will be shared in a brochure for incoming students. Is it likely
that the survey results will provide an accurate estimate of mean annual salary for all of the school's graduates?
Answer:
Yes
Step-by-step explanation:
The survey would definitely provide an accurate estimate for that. This is because while the participants are undertaking the survey, the fact that it was their school of study that gave them the survey, makes it less likely for them to lie about their income. And thus, after collecting the response from the participants, surely, they would have the income earnings from their former students and be able to calculate the mean income of them all

A=1/2h(b1+b2)
Please solve for b2

Step-by-step explanation:
Equation Solving
Given the formula:
[tex]\displaystyle A=\frac{1}{2}h(b_1+b_2)[/tex]
It's required to solve it for b2.
First, we eliminate denominators by multiplying by 2:
[tex]\displaystyle 2A=h(b_1+b_2)[/tex]
Divide by h:
[tex]\displaystyle \frac{2A}{h}=b_1+b_2[/tex]
Subtract b1:
