Answer:
b = 104/75 = 1 29/75 = 1.386666667
Step-by-step explanation:
5b−6+14(5b−6)+2=14+2
Use the distributive property to multiply 14 by 5b−6.
5b−6+70b−84+2=14+2
Combine 5b and 70b to get 75b.
75b−6−84+2=14+2
Subtract 84 from −6 to get −90.
75b−90+2=14+2
Add −90 and 2 to get −88.
75b−88=14+2
Add 14 and 2 to get 16.
75b−88=16
Add 88 to both sides.
75b=16+88
Add 16 and 88 to get 104.
75b=104
Divide both sides by 75.
b=104/75

Answer:
[tex]a_{15} = 2147483648[/tex]
Step-by-step explanation:
first, find the common ratio (r) by dividing the second term by the first term:
r = 32 / 8 = 4
next, write a formula for the geometric sequence:
[tex]a_{n} = a_{1} * (r)^{n-1} \\a_{15} = 8 * (4)^{14} \\a_{15} = 2147483648[/tex]

Janie has 2 3/4 yards or yellow ribbon. She uses 1/2 of the ribbon to decorate bookmarks for her cousin. How many yards of ribbon did Janie use for her bookmarks
Answer:
1 3/8 yards
Step-by-step explanation:
Janie has 2 3/4 yards of yellow ribbon. She uses 1/2 of the ribbon to decorate bookmarks for her cousin. How many yards of ribbon did Janie use for her bookmarks
The above question is calculated as:
2 3/4 yards × 1/2 of ribbon
= 2 3/4 × 1/2
= 11/4 × 1/2
= 11/8
= 1 3/8 yards
Therefore, Janie used 1 3/8 yards of ribbon for her bookmarks

There are 12 boys and 12 girls in Trevor's math class. His teacher will randomly select one student to present a homework problem to the class. Describe two different ways that rolling a six-sided die could be used to simulate the probability that Trevor's teacher will select a boy or girl.
Answer:
1/24
Step-by-step explanation:
1/24 bc there is 24 students in the class and the teachercould only choose 1 student
The two different ways that rolling a six-sided die could be used to simulate the probability that Trevor's teacher will select a boy or girl are:
- Assign one gender to even numbers and the other gender to odd numbers.
- Assign each student a number from 1 to 24, and then divide the numbers into two groups.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
To simulate the probability of selecting a boy or girl from Trevor's math class,
We can use a six-sided die in two different ways:
- Assign one gender to even numbers and the other gender to odd numbers.
For example, we can assign boys to even numbers (2, 4, 6) and girls to odd numbers (1, 3, 5).
We would then roll the die, and if it lands on an even number, we would consider the selected student to be a boy, and if it lands on an odd number, we would consider the selected student to be a girl.
We can repeat this process multiple times to simulate the probability of selecting a boy or girl.
- Assign each student a number from 1 to 24, and then divide the numbers into two groups:
one group for boys and the other group for girls.
For example, we can assign the boys the numbers 1 to 12 and the girls the numbers 13 to 24.
We would then roll the die and select the student with the corresponding number.
If the number is between 1 and 12, we would consider the selected student to be a boy, and if the number is between 13 and 24, we would consider the selected student to be a girl.
We can also repeat this process multiple times to simulate the probability of selecting a boy or girl.
Thus,
The two different ways that rolling a six-sided die could be used to simulate the probability that Trevor's teacher will select a boy or girl are:
- Assign one gender to even numbers and the other gender to odd numbers.
- Assign each student a number from 1 to 24, and then divide the numbers into two groups.

Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000143 mm, while the length of the second strain measures 0.0000000937 mm. How much larger is the first strain than the second?
Answer:
1.53 times
Step-by-step explanation:
Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000143 mm, while the length of the second strain measures 0.0000000937 mm. How much larger is the first strain than the second?
We would have:
First strain : Second strain
0.000000143 mm : 0.0000000937 mm
How much larger is the first strain than the second?
We divide both by the length of the second strain
0.000000143/0.0000000937 : 0.0000000937 / 0.0000000937

given that 65000 student where present in the competitive exam if 8/25 of them were boys find the number of girls present in the exam
Answer:
44200 of them were girls
Step-by-step explanation:
If the ratio is 8:25, we must find x:65000
In order to change the ratio 8:25 into x:65000, we must multiply 25 by 2600. So you have to multiply 8 by 2600 too
8 x 2600 = 20800
65000 (total students) - 20800 (boy students) = 44200 (girl students)

The flight path of a plane is a straight line from city J J to city K K. The roads from city J J to city K K take the long way around, traveling 9.4 9.4 miles south and then 15.1 15.1 miles east. How many degrees east of south is the plane's flight path, to the nearest tenth? M ∠ J ≈ ? M∠J≈
Answer:
58.1 degrees
Step-by-step explanation:
Given the following
JK = 9.4miles (towards south) negative y axis
If the move 15.1 miles towards east (that will be towards the positive x axis)
Using the SOH CAH TOA identity
opposite= 15.1 miles(side facing m<J)
adjacent= JK = 9.4miles
tan theta = opposite/adjacent
tan m<J = 15.1/9.4
tan m<J = 1.6063
m<J = arctan (1.6063)
m<J = 58.09 degrees
Hence the measure of m<J to the nearest tenth is 58.1 degrees

The equation of the line is of the form y = mx, What is the value of m?
Answer:
-4
Step-by-step explanation:
m is the slope
Answer:
m=-4
Step-by-step explanation:
in the formula y=mx, m is the slope. You can find it by looking at the graph, and finding two points that are defined on the grid. In this case, we can use (0,0) and (-1,4). Put it into the slope formula, (y2-y1)/(x2-x1). In this case, it would be (4-0)/(-1-0), which simplifies to 4/-1=-4. Therefore, m= -4
