Answer: 1 7/15 or 22/15
Step-by-step explanation: calculator
Answer:
1 7/15
Step-by-step explanation:
To solve this equation, we first need to find the least common denominator. In this case, the LCD of 3 and 5 is 15.
We can then convert our fractions to fifteenths.
Our new equation is 3 10/15 - 2 3/15.
From there, we can subtract normally and we get 1 7/15. We know that's in simplest form because 7 is a prime number
ryan has $0.75 worth of pennies and nickels. He has 3 more nickels than pinniped. Determine the number of pennies and the number of nickels that ryan has
Answer:
Ryan has 10 pennies and 13 nickels.
Step-by-step explanation:
Let the number of pennies be p and the number of nickels be n.
We have two unknowns, the number of pennies and the number of nickels, so we need two equations. One equation will deal with the value of the coins. The other equation will deal with the number of coins.
Value of coins:
1 penny is worth $0.01; p pennies are worth 0.01p.
1 nickel is worth $0.05; n nickels are worth 0.05n.
The total amount the coins are worth is
0.01p + 0.05n
The coins are worth $0.75, so we have our first equation.
0.01p + 0.05n = 0.75 Equation 1
Number of coins:
He has p pennies.
The number of nickels is 3 more than the number of pennies.
Since the number of pennies is p, then the number of nickels is p + 3.
That gives us our second equation.
n = p + 3 Equation 2
System of equations:
Now we have a system of two equations in two unknowns:
0.01p + 0.05n = 0.75
n = p + 3
Since the second equation is already solved for n, we can use the substitution method.
Replace n in the first equation with p + 3.
0.01p + 0.05n = 0.75
0.01p + 0.05(p + 3) = 0.75
Distribute the 0.05
0.01p + 0.05p + 0.15 = 0.75
Combine like terms on the left side.
0.06p + 0.15 = 0.75
Subtract 0.15 from both sides.
0.06p = 0.6
Divide both sides by 0.06.
p = 0.6/0.06
p = 10
Now we substitute 10 for p in the second equation to find the value of n.
n = p + 3
n = 10 + 3
n = 13
He has 10 pennies and 13 nickels.
Check:
A) 13 - 10 = 3 He does have 3 more nickels than pennies.
B) $0.01(10) + $0.05(13) = $0.10 + $0.65 = $0.75
The number of coins and the value of the coins both check out, so our answer is correct.
Answer: Ryan has 10 pennies and 13 nickels.

All side lengths in quadrilateral PQRS measure 6 units. A transformation maps
PQRS to P'Q'R'S'. All sides of P'Q'R'S' measure 3 units. Is the mapping isometric?
Explain.
An isometric transformation is a transformation that preserves the distance and angles between a pre-image and its image. Examples are: translation, reflection, rotation.
Answer:
No, the side lengths are not preserved.
This is a non isometric transformation.

The perimeter of a rectangle is 80 cm. The width is 10 cm more than twice the length. What
is the length and width of this rectangle? P=2W+2L
Answer:
L=10cm , W=30cm
Step-by-step explanation:
First use the given that W=10+2*L
Use P=2W+2L=80, substitute W in the perimeter formula
2(10+2L)+2L=80 and solve for L,
20+4L+2L=80 isolate variable L and combine like terms,
6L=80-20,
L=10, so W=10+2*10=10+20=30

A person who weighs 100 pounds on Earth weighs 16.5 pounds on the moon. If a boy weighs 60 pounds on Earth, how much does he weigh on the moon?
Answer:
The answer is 10 Pounds.
Step-by-step explanation:
You get 10 pounds because you divide your weight by 6 and 60 divided by 6 is 10.
Answer:
3.636363636
Step-by-step explanation:
Because that is 16.5 percent of 60, you can find this by dividing 60 by your percentage your trying to find of it, 16.5 in this case.

Step-by-step explanation:
A bacteria triples its original population in 25 hours (A=3A0). How big will its population be in 100 hours?
Answer:
81 times the original size.
Step-by-step explanation:
AA0ktA=3A0=?=?=25hours=A0ekt
Substitute the values in the formula.
3A0=A0ek⋅25
Solve for k. Divide each side by A0.
3A0A0=e25k
Take the natural log of each side.
ln3=lne25k
Use the power property.
ln3=25klne
Simplify.
ln3=25k
Divide each side by 25.
ln325=k
Approximate the answer.
k≈0.044
We use this rate of growth to predict the number of bacteria there will be in 100 hours.
AA0ktA=3A0=?=ln325=100hours=A0ekt
Substitute in the values.
A=A0eln325⋅100
Evaluate.
A=81A0
At this rate of growth, we can expect the population to be 81 times as large as the original population.
Answer:
81

Find the measure of each angle 9-17. PLZZZ HELP will give brainliest!!!! Pleaseee help!!!!!
Answer:
Step-by-step explanation:
l║m and line t is the transversal line intersecting these parallel lines.
9). If m∠7 = 100°,
m∠3 = m∠7 = 100° [Since, ∠3 and ∠7 are alternate interior angles]
10). m∠7 = 95°
m∠6 + m∠7 = 180° [Consecutive interior angles]
m∠6 = 180° - m∠7
m∠6 = 180° - 95°
m∠6 = 85°
11. m∠1 = 120°
m∠1 = m∠5 = 120° [Alternate exterior angles]
12. m∠4 = 20°
Since, m∠4 = m∠6 = 20° [Vertically opposite angles]
And m∠6 + m∠7 = 180° [Consecutive interior angles]
20° + m∠7 = 180°
m∠7 = 160°
13. m∠3 = 140°
m∠3 + m∠6 = 180° [Linear pair of angles]
m∠6 = 180° - m∠3
= 180° - 140°
= 40°
m∠6 = m∠8 = 40° [Corresponding angles]
14. m∠4 = 30°
m∠4 + m∠1 = 180° [Consecutive exterior angles]
m∠1 = 180° - 30°
m∠1 = 150°
15. m∠4 = 40°
m∠4 = m∠2 = 40° [Corresponding angles]
16. m∠7 = 125°
m∠6 + m∠7 = 180° [Consecutive interior angles]
m∠6 = 180° - 125°
= 55°
m∠6 = m∠4 = 55° [Vertically opposite angles]
17. m∠1 + m∠3 = 230°
Since, m∠1 = m∠3 [Corresponding angles]
m∠3 + m∠3 = 230°
m∠3 = [tex]\frac{230}{2}[/tex]
= 115°
m∠3 + m∠6 = 180° [Linear pair of angles]
m∠6 = 180° - 115°
m∠6 = 65°
which expression is the sun of cubes?
Answer:
Step-by-step explanation: We have been given 4 expressions. We are asked to choose the expression that represents sum of cubes.
We know that sum of cubes is in form .
We can see that 1st and 2nd option has a negative sign. Therefore, these options cannot be sum of cubes.
Let us check 3rd and 4th options one by one.
We can rewrite our expression by writing terms as cubes:
Therefore, expression is a sum of cubes.
In 4th expression, we can see that . We cannot represent it as a cube. Similarly, we cannot represent as a cube. Therefore, 4th expression is not correct.
