The ratio of the side length of Square A to the side length of Square B is 4:9. The side length of Square A is 12 yards. What is the perimeter of Square B?

Answers

A/B : 4/9 = 12/B
cross multiply
(4)(B) = (9)(12)
4B = 108
B = 108/4
B = 27

P = 4a...where a is the length of one side
P = 4(27)

in order for Brady to earn a b in his biology course, his test scores must average at 80%. ON the first 5 tests, he has an average of 77%. There is one test remaining in the course. What is the minimum score Brady needs to earn on the last test to receive a b in the class?

Answers

In order for him to have a 77% on his first 5 tests, that means the total amount of points earned on those 5 tests was 385 points out of 500 points.
(77*5 out of 5*100 points)
So if we want to add a test and have a 80% average this is what we have to do:
(385+x)/6 = 80 (multiply by 6 on both sides)
385 + x = 480 (minus 385 on both sides)
x = 95

Answer:

Brady needs to earn a 95% on the final test

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

Before we can actually solve this we need to create a formula that calculates the grade of the last test in order to get an average of 80%. Since he got a 77% average for his first 5 tests, we can multiply 0.77 by 5, add the final test and then divide by the total amount of tests taken. Like so,

[tex]0.80 = \frac{(0.77*5)+x}{6}[/tex]

[tex]0.80 = \frac{3.85+x}{6}[/tex] .... multiply both sides by 6

[tex]4.8 = 3.85+x[/tex] ... subtract both sides by 3.85

[tex]0.95 = x[/tex]

Finally, we can see that Brady needs to earn a 95% on the final test in order to increase his overall average to 80%.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

the value of the digit 9 is 2,107,954

Answers

The value of the digit 0 is 10 thousand.
What you have to do is break down the numbers so since there is no 0 in 954, then you would move on to the next 3 sets of numbers of which, if the number was just 107, you could see that the 0 is in the tens place and since it is actually 107,000, then you would say that the 0 is in the ten thousands place.

What is the value of p? 3+17p=−32−11p

Answers

3+17p=−32−11p
17p + 11p = -32 - 3
28p = -35
p = -35/28
p = -5/4
or
p = -1 1/4

The value of p in this equation 3 + 17p = -32 - 11p is -5/4. To find the value of p, we need to solve the equation: 3 + 17p = -32 - 11p

First, let's gather all the terms involving p on one side of the equation:

17p + 11p = -32 - 3

Now, combine the p terms:

28p = -35

Now, isolate p by dividing both sides of the equation by 28:

p = -35 / 28

To simplify the fraction, we can divide both the numerator and denominator by the greatest common divisor (GCD) of 35 and 28, which is 7: p = -5/4

So, the value of p is -5/4.

Greatest common factor or 60 and 20

Answers

To find the greatest common factors of these 2 numbers, first write them as product of prime numbers.

(a prime number is a number whose only factors are 1 and themselves, for example: 2, 3, 11 ...etc)

To write the numbers as product of prime factors, just divide them continuously until all factors are primes:

[tex]60=6\cdot10=(2\cdot3)\cdot(2\cdot5)=2\cdot2\cdot3\cdot5\\\\20=2\cdot10=2\cdot(2\cdot5)=2\cdot2\cdot5[/tex]

So the greatest common factor is [tex]2\cdot2\cdot5=4\cdot5=20[/tex]

Answer: 20

The greatest common factor of the numbers 60 and 20 is 10.

We have,

To find the greatest common factor (GCF) of 60 and 20, we can list the factors of both numbers and identify the largest factor they have in common.

The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60.

The factors of 20 are: 1, 2, 4, 5, 10, 20.

From the list above, we can see that the common factors of 60 and 20 are 1, 2, 4, 5, and 10.

Among these common factors, the largest one is 10.

When Mr. J. Raff took his two children to the zoo, their tickets cost $8.75. The next family in line was Mrs. Ella Fant with Grandpa and the five Fant kids. Their tickets cost a total of $19.75. How much does the zoo charge for each adult and for each child?

Answers

A + 2K = 8.75
2A + 5K = 19.75
Change the first expression so that we can subtract the As
2A + 5K = 19.75
2A+4K= 17.50
If the signs are the same, subtract one expression from another
K= 2.25
substitute K into any expression to get A
A+4.50= 8.75
Subtract 4.50
a=4.25

K=$2.50
A= $4.25

Final answer:

The zoo charges approximately $4.42 for each adult and $0.92 for each child.

Explanation:

To determine the cost of an adult ticket, we can subtract the cost of the children's ticket from the total cost. Let's set up a system of equations using variables for the cost of an adult ticket (a) and the cost of a child ticket (c):

a + 2c = 8.75

a + 5c = 19.75

Multiplying the first equation by 5 and subtracting the second equation from it, we get:

5a + 10c - a - 5c = 43.75 - 19.75

4a + 5c = 24

Now we can solve this system of equations to find the values of 'a' and 'c'.

Multiplying the first equation by 4 and subtracting the second equation from it, we get:

4a + 8c - 4a - 20c = 35 - 24

-12c = -11

c = -11 / -12

c = 11 / 12

Substituting the value of 'c' back into the first equation, we get:

a + 2 * (11 / 12) = 8.75

a + 11 / 6 = 8.75

a = 8.75 - 11 / 6

a = 53 / 12

So, the zoo charges approximately $4.42 for each adult and $0.92 for each child.

r = 2/3t + v , for t
need answer a how u got it

Answers

R= 2/3t + v
R-v=2/3t
3(R-v)=2t
t= 3(R-v)/2

Final answer:

To solve the equation r = 2/3t + v for t, subtract v from both sides and then multiply by the reciprocal of 2/3. The final equation is t = (3/2)(r - v).

Explanation:

You are looking to solve the equation r = 2/3t + v for t. To do this, you need to isolate t on one side of the equation. Here are the steps:

Subtract v from each side. This gives us: r - v = 2/3t. To get t alone, we need to get rid of 2/3. Therefore multiply both sides of the equation by the reciprocal of 2/3, which is 3/2, resulting in: (3/2)(r-v) = t.

So the answer is t = (3/2)(r-v).
