ok so first you need to change both of them so they have the same denominator: LCM of 16 and 6=48
48/16×15=45
48/6=8
45/48+8/48=53/48
=1 5/48

d x 54 = 324,
What does d equal?
who ever answers first gets brainlest
Answer:
d = 6
Step-by-step explanation:
d × 54 = 324
Divide both sides by 54.
d × 54/54 = 324/54
d = 6
Answer:
D=6
Step-by-step explanation:
54 x 6=324
Here is how i know.
I times the tens 6 times so 50 x 6=300
50 x 1=50
50 x 2=100
50 x 3=150
50 x 4=200
50 x 5=250
50 x 6=300
Then I did ones(4)
4 x 1=4
4 x 2=8
4 x 3=12
4 x 4=16
4 x 5=20
4 x 6=24.
Then I added it 50 x 6=300 + 4 x6=24=324 so 54 x 6=324.
Hope it helps have a great day:)
Write -9/22 as a decimal.
Answer:
-0.40909090909
Step-by-step explanation:
it is not not terminating or repeating so, it is not a rational number.
The solution shown for the equation is incorrect. What is the correct solution? What is the error?
(CHECK IMAGE BELOW FOR EQUATION)
What is the error?
A. The right side of the equation should be 6 after dividing each side by -4.
B. The right side of the equation should be 8 after subtracting -8 from each side.
C. The left side of the equation should be - r after dividing each side by -4.
D. The left side of the equation should be - 8+4r after distributing.
Answer:
The answer is D
Step-by-step explanation:
- x - equals positive so it would be -8+4r
Answer:
D
Step-by-step explanation:
Honestly I can't giv a detailed explanation, apologies. Negatives multiplied result in positives. Since -4 is negative and -r is also negative, expanded form should be +4r. Also the answer is r=6 in case you need it.

If i have 1 liter of cats and i give away 2.5 pints of cats how many cats do i have left (cats are technically a liquid)
Answer:
1 US pint ≈ 0.473 US liters
Therefore, 2.5 pints ≈ 2.5 × 0.473 ≈ 1.18 liters
1.18 > 1 so you will have a negative amount left (-0.18 liters)

Vishal deposits $65 into a new savings account. The account earns 7.5% interest per year. No money is added or removed
from the savings account for 3 years. What is the total amount of money in his account at the end of 3 years.
Answer:
$[tex]79.23[/tex] After 3 years
Step-by-step explanation:
Use I P R T it's a method for simple interest
I = Interest
P = Amount of money
R = Percent in decimal
T = Time in years
Answer:
I = [tex]x[/tex] (we dont know yet)
P = $[tex]65[/tex]
R = [tex]7.5[/tex]% [tex]= 0.075[/tex]
T = [tex]3[/tex] [tex]years[/tex]
Steps:
1. Set up your numbers with the method I P R T.
2. $65 will be your amount of money.
3. 7.5% needs to be converted because you will need to multiply later on in the problem. Simply move 2 places to the left to convert your percent into a decimal.
4. They want to know the total amount of money in his account at the end of 3 years. So 3 years will be your time in years.
5. After setting up your problem you need to multiply your Amount of money x percent as decimal x time in years.
[tex]65(0.075)(3)=14.63\\[/tex] [tex]Interest\\[/tex]
6. After you find your interest you need to add your amount of money + interest.
[tex]65 + 14.63 = 79.23[/tex] Money after 3 years
hope this helped

Match each table of information to its constant of proportionality.
Answer:
Table 1: 2
Table 2: 10
Step-by-step explanation:
Constant of proportionality - the ratio between two proportional quantities.
We see that the ratio between the two rows of numbers in the first table is 2 because (4 / 2 = 2), (6 / 3 = 2), (8 / 4 = 2) and so on and so forth.
We see that the ratio between the two rows of numbers in the second table is 10 because (20 / 2 = 10), (30 / 3 = 10), (40 / 4 = 10) and so on and so forth.
Answer:
Table 1 is 2, Table 2 is 10.
Step-by-step explanation:
Table 1: The constant of proportionality is 2 because 4/2 is 2, 6/3 is 2, etc.
Table 2: The constant of proportionality is 10 because 20/2 is 10, 30/3 is 10, etc.

An experiment involves rolling a die and drawing a card from a standard deck of 52 cards.
What is the probability that the die lands on 4 and the card is a heart?
Answer:
1/24
Step-by-step explanation:
chance of rolling 4 - 1/6
Chance of pulling a heart - 13/52, or 1/4
To find P(roll a 4, and pull a heart) you must multiply the 2 answers to find your final answer. So, 1/4 x 1/6 = 1/24

Answer:
yes, because the value of the angles in both the triangles are the same
Step-by-step explanation:
in triangle 1, the given value is 47 and 78. we can find the unknown value by taking 180 and minus 47 and 78, you will get 55°. in triangle 2, the given value is 47 and 55, like the previous step, take 180 and minus 55 and 47. you will get 78.
and now, you can find out that the three values in both the triangles are the same
Answer:
Yes, I guess you can say the triangles are similar. For example, all 4 sides are an acute angle. In addition, both triangles are missing 1 degree shown on the picture.

indirect measures and diagram?
Answer:
9. The man is 6 feet tall
10. Ms. Dydek's shadow would be 4 ft 6.3 inches
Step-by-step explanation:
Problem 9:
The 136 feet tall Ferris wheel casts a shadow of 34 feet so the shadow:object ratio is 34:136.
The man's shadow is 1.5 feet so this is what we're solving for:
1.5:x
34: 136
First, we need to find what 1.5 was multiplied by to get 34:
34/1.5 = 22 2/3 or 68/3
This means that 68/3x = 136:
68/3x = 136
x = 6
The man is 6 feet tall
Problem 10:
A 6 foot 4 inch or 76 inch tall person casts a shadow of 4 feet or 48 inches. This makes the shadow:object ratio 48:76.
We are trying to find the length of the shadow of a 7 foot 2 inch or 86 inch tall person:
48:76
x:86
First, determine what 76 was multiplied by to get 86:
86/76 = 43/38
This means that x = 48*(43/38).
x = 2064/38
x = 54 6/19 or 54.3in
Margo Dydek's shadow would be 54.3 inches or 4 feet and 6.3 inches long.
Solve -9.4 > 1.7x + 4.2.
A. xs-8
B. x<8
C. x 2-8
D. x 8
Answer:
-8 < x
Step-by-step explanation:
To solve -9.4 > 1.7x + 4.2, we can use the following steps:
Subtract 4.2 from both sides of the inequality to isolate 1.7x on the right side.
-9.4 - 4.2 > 1.7x + 4.2 - 4.2
-13.6 > 1.7x
Divide both sides by 1.7 to solve for x. Remember to flip the inequality sign when dividing by a positive number.
