Answer:
The equation connecting c and d is: c = kdThe value of c when d=8 is: 48The value of d when c=54 is: 9Step-by-step explanation:
Proportion can be defined as the effect of changing one quantity on the other.
Given that
‘c’ is directly proportional to‘d’
It can mathematically be written as:
c∝d
A constant is introduced in the equation when the proportionality symbol will be removed. The constant is called constant of proportionality
[tex]c =kd[/tex]
Given that
c = 24 when d = 4
Putting the values
[tex]24 = k(4)\\k = \frac{24}{4}\\k = 6[/tex]
Putting the value of k
[tex]c = 6d[/tex]
Putting d = 8
[tex]c = 6(8) = 48[/tex]
Putting c = 54
[tex]54 = 6d\\d = \frac{54}{6}\\d = 9[/tex]
Hence,
The equation connecting c and d is: c = kdThe value of c when d=8 is: 48The value of d when c=54 is: 9Daisy went deep sea diving. She makes the first stop in her descent at 25 meters below the surface of the water. From that point she dives down further, stopping every 5 meters. If she makes 3 additional stops, which number represents her position, relative to the surface of the water?
Answer:
-45 M
Step-by-step explanation:
The surface of the water is at 0 m. Heights above the surface are positive and depths below the surface are negative.

9514 1404 393
Answer:
2a. 0.7, 0.3, -0.1, -0.5, -0.9
2b. 1, 3, 9, 27, 81
3a. geometric; r = 1/5
3b. arithmetic; d = -9
4. 234
5. 1/32
Step-by-step explanation:
2a. Start with the first term and add the common difference to get the next term.
0.7
0.7 -0.4 = 0.3
0.3 -0.4 = -0.1
-0.1 -0.4 = -0.5
-0.5 -0.4 = -0.9
The first 5 terms are 0.7, 0.3, -0.1, -0.5, -0.9.
__
2b. Start with the first term and multiply by the common ratio to get the next term.
The first 5 terms are 1, 3, 9, 27, 81.
__
3a. Obviously, the difference between 40 and 8 is not the same as the difference between 8 and 1.6. So, we look to see if the ratios are the same. They are:
8/40 = 1.6/8 = 1/5
This is a geometric sequence with a common ratio of 1/5.
__
3b. If the sign changes, but does not alternate, it cannot be a geometric sequence. The common difference is ...
-5 -4 = -14 -(-5) = -9
This is an arithmetic sequence with a common difference of -9.
__
4. Use n=50 and evaluate.
[tex]a_{50}=-11+5(50-1)=\boxed{234}[/tex]
__
5. Use n=7 and evaluate.
[tex]g_7=2\cdot\left(\dfrac{1}{2}\right)^{7-1}=\dfrac{2}{2^6}=\dfrac{1}{2^5}=\boxed{\dfrac{1}{32}}[/tex]

What's 4/5 as a percentage?
Answer:
80%
Step-by-step explanation:
% is out of 100 so make the denominator of 4/5 to be 100:
4/5 times 20/20 = 80/100 = 80%
Answer:
80%
Step-by-step explanation:
4 divided by 5 equal .8
.8 x 100 equals 80
It's multiplied by 100 because usually percentages are out of 100.
OR
You can move the decimal in .8 to 2 space to the right
If the perimeter of the triangle is 60, what is the value of y?
Answer:
y = 5Step-by-step explanation:
Given:
In the right triangle the hypotenuse is 5y, one leg is 4y, the other leg is missingMissing side of the triangle is:
√(5y)² - (4y)² = √(3y)² =3yPerimeter is 60:
3y + 4y + 5y = 6012y = 60y = 60/12y = 5Help and I’ll give brainlest answer
Need a quick answer please
Answer:
X=22
Step-by-step explanation:
All the angles in every triangle must add up to 180 so we can subtract 23 and 135 from 180 to get 22.
Answer:
x=22
z=135
y=23
Step-by-step explanation:
First, start with x in the picture. All angles in a triangle add up to 180 degrees. So, add 135+23 and then subtract that from 180.
135+23=158
180-158 = 22 degrees
Angle z is congruent to the larger angle on the other triangle. So, that means z=135.
Angle y is equal to the angle across from it. Y=23

Step-by-step explanation:
2² * 3 * 5 = 4 * 3 * 5 = 60.
3² * 5² = 9 * 25 = 225.
Answer:
A) 60
B) 225
Step-by-step explanation:
A) The factorization of a number is finding the factors that, when multiplied together, form the original number. As an example, one instance of the factorization of 24 would be 6 and 4, since 6 × 4 = 24.
The prime factorization of a number is finding the factors of a number and restricting them to only include primes, which are numbers with no other factors except themselves and 1.
Hence, all you have to do for A) is to multiply all the factors together, which is [tex]2^{2} \cdot 3 \cdot 5[/tex], which equates to 60.
B) Since this three-digit number has 5 as a prime factor, it has to end in a 5 or 0. This narrows our search hugely.
Accounting for the fact it has a 3 as a prime factor, the number has 3 × 5 = 15 as a factor. This yet again narrows our search hugely.
Finally, to find the square number, there is actually a really simple way of doing this; simply square 15 to get 225. We can confirm this is a square number because we squared 15 to get that number; hence, 225 is an answer.
Hope this helped!
