Answer:
14 im pretty sure
Step-by-step explanation:
.
To calculate the number of hits Courtney must get in her next 50 at-bats to achieve a .300 batting average, we'll need to consider her current stats.
The batting average is determined by dividing the total number of hits by the total number of at-bats. Currently, Courtney has 14 hits out of 50 at-bats, which gives her a batting average of [tex]14/50 = 0.28[/tex] or a 28% average. To achieve a .300 batting average, she needs her hits to make up 30% of her total at-bats.
Since Courtney will have 100 at-bats after her next 50, she'll need to have 30 hits to achieve her desired average. To calculate the number of hits needed in her next 50 at-bats, we subtract her current hits from the target hits. Therefore, Courtney needs [tex]30 hits - 14 hits = 16[/tex] hits in her next 50 at-bats to finish with a .300 average.

factorise completely 3m^2-48
Answer:
3 (m^2 - 16)
Step-by-step explanation:
factoring means taking out a common multiple of all the terms in the expression
in this case, if you multiply 3 and m^2, 3 and -16, you would get 3m^2-48
so you take the three and put it outside of the parenthesis that contains the factored terms
this leaves you with 3 (m^2 - 16)

-10=-10+ 7m
What is the answer?
Answer:
0 = 7m
0 = m
m = 0
It is 0 because first you would have to cancel -10 on both of the sides then divide both of the sides by 7 then switch the sides which is 0
The result of the equation -10 = -10 + 7m is m = 0
The given equation is:
-10 = -10 + 7m
Add 10 to both sides of the equation
-10 + 10 = -10 + 10 + 7m
0 = 7m
Rewrite the equation as:
7m = 0
Divide both sides of the equation
7m/7 = 0/7
m = 0
This is because 0 divided by any number is 0
Therefore, the result of the equation -10 = -10 + 7m is m = 0

Renate wins a $20 gift card to an online music site. After Renetta purchased 16 songs, the gift card has a remaining balance of zero dollars. Which equation represents the relationship between Y, the remaining balance on Manetta‘s gift card, and X, the number of songs purchased?
Answer:
b. 5x + 4y = 80
Step-by-step explanation:
Let us assume the remaining balance left be Y
and, the number of songs purchased be X
Given that
Wins a gift card of $20
And, the songs purchased is 16
Now if we take the fraction
= 20 ÷ 16
= 5 ÷ 4
So if we reverse this fraction
So it could be 5x and 4y
And, the amount that would come is
= $20 × 16 ÷ 4
= 80
So, the equation is 5x + 4y = 80
Hence, the correct option is b.
steve saw 313 birds during a bird-watching trip to Yellowstone National park. he observes 15 more trumpeter swans than sandhill cranes. he saw twice as many mountain chickadees as ducky grouses. how many birds of each type did steve observe if he saw half as many trumpeter swans as ducky grouses
Answer:
trumpeter swans = 41sandhill cranes = 26mountain chickadees = 164ducky grouses = 82Step-by-step explanation:
Total number of birds = 313
trumpeter swans = ssandhill cranes = cmountain chickadees = mducky grouses = gWe have equations below based on given:
s = c + 15
m = 2g ⇒ m = 2(2s) = 4s ⇒ m = 4(c + 15)g = 2s ⇒ g = 2(c + 15)s + c + m + g = 313Substituting m, g and s as above in the last equation and finding the value of c:
c + 15 + c + 2(c + 15) + 4(c + 15) = 3137(c + 15) + c = 3137c + c + 105 = 3138c = 313 - 1058c = 208c = 208/8c = 26Then finding the other values:
s = 26 + 15 = 41g = 2s = 2*41 = 82m = 2g = 2*82 = 164Ast year, Saleh opened an investment account with $8600. At the end of the year, the amount in the account had decreased by 23.5%. How much is this decrease in dollars? How much money was in his account at the end of last year?
Given:
Initial amount = $8600
The amount in the account had decreased by 23.5%.
To find:
Decrease in amount and amount at the end of last year.
Solution:
The amount in the account had decreased by 23.5%. So,
Decreased amount = 23.5% of 8600
[tex]=\dfrac{23.5}{100}\times 8600[/tex]
[tex]=23.5\times 86[/tex]
[tex]=2021[/tex]
Now, the amount at the end of the last year is
Amount = Initial value - Decreased value
[tex]Amount=8600-2021[/tex]
[tex]Amount=6579[/tex]
Therefore, the decreased value is $2021 and the amount at the end of last year is $6579.

1. The ratio of the measures of the sides of a triangle is 5:6:8, and
its perimeter is 159.6 mm. Find the measure of the shortest side of
the triangle
Answer:
42mm
Step-by-step explanation:
Let the shortest side of the triangle be 5x, the middle side be 6x, and the longest side be 8x.
5x+6x+8x = 159.6
19x = 159.6
x = 159.6 ÷ 19
x = 8.4
Shortest side of triangle (5x) = 8.4 × 5

8 - (7/10)t = 6 - (1/5)t
Answer:
t = 4
Step-by-step explanation:
Solve for t:
8 - (7 t)/10 = 6 - t/5
Hint: | Put the fractions in 8 - (7 t)/10 over a common denominator.
Put each term in 8 - (7 t)/10 over the common denominator 10: 8 - (7 t)/10 = 80/10 - (7 t)/10:
80/10 - (7 t)/10 = 6 - t/5
Hint: | Combine 80/10 - (7 t)/10 into a single fraction.
80/10 - (7 t)/10 = (80 - 7 t)/10:
1/10 (80 - 7 t) = 6 - t/5
Hint: | Put the fractions in 6 - t/5 over a common denominator.
Put each term in 6 - t/5 over the common denominator 5: 6 - t/5 = 30/5 - t/5:
(80 - 7 t)/10 = 30/5 - t/5
Hint: | Combine 30/5 - t/5 into a single fraction.
30/5 - t/5 = (30 - t)/5:
(80 - 7 t)/10 = (30 - t)/5
Hint: | Make (80 - 7 t)/10 = (30 - t)/5 simpler by multiplying both sides by a constant.
Multiply both sides by 10:
(10 (80 - 7 t))/10 = (10 (30 - t))/5
Hint: | Cancel common terms in the numerator and denominator of (10 (80 - 7 t))/10.
(10 (80 - 7 t))/10 = 10/10×(80 - 7 t) = 80 - 7 t:
80 - 7 t = (10 (30 - t))/5
Hint: | In (10 (30 - t))/5, divide 10 in the numerator by 5 in the denominator.
10/5 = (5×2)/5 = 2:
80 - 7 t = 2 (30 - t)
Hint: | Write the linear polynomial on the left hand side in standard form.
Expand out terms of the right hand side:
80 - 7 t = 60 - 2 t
Hint: | Move terms with t to the left hand side.
Add 2 t to both sides:
2 t - 7 t + 80 = (2 t - 2 t) + 60
Hint: | Look for the difference of two identical terms.
2 t - 2 t = 0:
2 t - 7 t + 80 = 60
Hint: | Group like terms in 2 t - 7 t + 80.
Grouping like terms, 2 t - 7 t + 80 = 80 + (2 t - 7 t):
80 + (2 t - 7 t) = 60
Hint: | Combine like terms in 2 t - 7 t.
2 t - 7 t = -5 t:
-5 t + 80 = 60
Hint: | Isolate terms with t to the left hand side.
Subtract 80 from both sides:
(80 - 80) - 5 t = 60 - 80
Hint: | Look for the difference of two identical terms.
80 - 80 = 0:
-5 t = 60 - 80
Hint: | Evaluate 60 - 80.
60 - 80 = -20:
-5 t = -20
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of -5 t = -20 by -5:
(-5 t)/(-5) = (-20)/(-5)
Hint: | Any nonzero number divided by itself is one.
(-5)/(-5) = 1:
t = (-20)/(-5)
Hint: | Reduce (-20)/(-5) to lowest terms. Start by finding the GCD of -20 and -5.
The gcd of -20 and -5 is -5, so (-20)/(-5) = (-5×4)/(-5×1) = (-5)/(-5)×4 = 4:
