Answer:
8[tex]\frac{1}{7}[/tex] (in mixed fraction)
Step-by-step explanation:
4 ÷ [tex]\frac{5}{7}[/tex]
can also be written as
[tex]\frac{4}{1}[/tex] ÷ [tex]\frac{5}{7}[/tex]
[tex]\frac{4}{1}[/tex] ×[tex]\frac{7}{7}[/tex] [tex]\frac{5}{7}[/tex] × [tex]\frac{1}{1}[/tex] (to do the denominators same)
[tex]\frac{28}{7}[/tex] ÷ [tex]\frac{5}{7}[/tex]
= [tex]\frac{28/5}{7}[/tex]
= [tex]\frac{5.6}{7}[/tex]
= [tex]\frac{5.6}{7}[/tex] × [tex]\frac{10}{10}[/tex] (to remove the decimal point)
= [tex]\frac{56}{7}[/tex]
= 8[tex]\frac{1}{7}[/tex] (in mixed fraction)

A baseball team won 16 games and lost 11. At this rate, how many games will it win in a 162-game schedule?
==========================================================
Explanation:
The team won 16 games and lost 11 so far. At this point in the season, they played 16+11 = 27 games total. Their win rate is 16/27.
Set this equal to x/162 which is the win rate for winning x games out of 162 played over the entire season.
Solve for x.
x/162 = 16/27
27x = 162*16 ... cross multiplication
27x = 2592
x = 2592/27
x = 96
The team would win 96 games if it kept the same winning rate going.
Notice that 16/27 = 0.5926 = 59.26% and how 96/162 = 0.5926 = 59.26% as well (both are approximate). This helps confirm we have the correct answer.
-------------------------
Here's another slightly longer way to solve. If you prefer the first method above, then ignore this section.
w = number of games won over the entire 162 game season
162-w = number of games lost over the entire season
w/(162-w) = win to loss ratio
16/11 = win to loss ratio after winning 16 games and losing 11
Setting those last two expressions equal to each other and solving for w gets us...
w/(162-w) = 16/11
11w = 16(162-w)
11w = 2592-16w
11w+16w = 2592
27w = 2592 ... this hopefully looks a bit familiar from before
w = 2592/27
w = 96 games won

Draw a graph for each inequality.
Answer:
Step-by-step explanation:
[tex]\frac{3a-1}{8} = \frac{a+9}{4}[/tex]
Answer:
a = 19
Step-by-step explanation:
[tex] \frac{3a - 1}{8} = \frac{a + 9}{4} [/tex]
[tex]4(3a - 1) = 8(a + 9)[/tex]
[tex]12a - 4 = 8a + 72[/tex]
[tex]12a - 8a = 72 + 4[/tex]
[tex]4a = 76[/tex]
[tex]a = 76 \div 4[/tex]
[tex]a = 19[/tex]
Jillian simplified the expression 7 + 3 . (10 -6) ^2 in the following way:
7 + 3 . (10 - 6) ^2
7+ 3 . (4)^2
7+3 . 16
10 . 16
160
Part: A Explain, using the complete sentences, what Jillian’s error was
Part B: show how the expression should have bee simplified using a similar format.
Please help me how should I explain it
Answer:
Part A: Jillian added 7+3 first rather than multiplying 3*16 b/c multiplication comes before addition
Part B:
7 + 3 * (10 - 6) ^2
7+ 3 * (4)^2
7+3 * 16
7 + 48
55
Step-by-step explanation:
Answer:
Part A:
Jillian's error was that they added the 7 and the 3 to get 10 and then multiplied by 16. Jillian should have multiplied the 3 and the 16 first and then added 7. This is because multiplication comes before addition in PEMDAS.
Part B:
7+3×(10-6)^2
7+3×(4)^2
7+3×16
7+48

if ad and pm are medians of two similar triangles abc and pqr such that ad:pm=4:9, then calculate ar. triangle abc/ar. triangle pqr
Answer:
4/9
Step-by-step explanation:
ad(base)/2 = abc
4x(4y)/2 = 4xy/2 = 2xy
pm(base)/2 = pqr
9x*9y/2 = 9xy/2 = 4.5xy
2xy/4.5 xy = 2/4.5 = 4/9

If LM = X+3, MN = 2x, LN = 4x, and M is between L and N, then LN = ?
Answer:
LN = 12
Step-by-step explanation:
L______M_____N
LM = x+3
MN = 2x
LN = 4x
M is the midpoint of LN
LN= ?
LM + MN = LN
x + 3 + 2x = 4x
x + 2x + 3 = 4x
3x + 3 = 4x
-3x -3x
----------------------
3 = 1x
/1 /1
----------------------
3 = x
LN = 4x
= 4 (3)
= 12
LN = 12
Answer:
LN = 12
Step-by-step explanation:
If LM = X+3, MN = 2x, LN = 4x, and M is between L and N, then LN = 12.
solve the following equation(2m)/3 + 1/2 - m/5 = (4m)/5 + 5
Answer:
m = - 13.5
Step-by-step explanation:
Given
[tex]\frac{2m}{3}[/tex] + [tex]\frac{1}{2}[/tex] - [tex]\frac{m}{5}[/tex] = [tex]\frac{4m}{5}[/tex] + 5
Multiply through by 30 ( the LCM of 3, 2, 5 ) to clear the fractions
20m + 15 - 6m = 24m + 150 , that is
14m + 15 = 24m + 150 ( subtract 24m from both sides )
- 10m + 15 = 150 ( subtract 15 from both sides )
- 10m = 135 ( divide both sides by - 10 )
m = - 13.5

For what values of x is the equation X^2-x=20 true?
Answer: x = 5 or x = -4
Step-by-step explanation:
Given equation
x² - x = 20
Subtract 20 on both sides
x² - x - 20 = 0
Cross factorize the equation
x -5
x 4
Factorize the equation
(x - 5) (x + 4) = 0

Perform the indicated operations. Write the answer in standard form, a+bi.
(9 + 2i)(9 - 2i)
Answer:
It can't be expressed in that form
Step-by-step explanation:
From difference of two squares:
[tex]{ \boxed{(a + b)(a - b) = ( {a}^{2} - {b}^{2} )}}[/tex]
a » 9
b » 2i
[tex](9 + 2i)(9 - 2i) = \{ {(9)}^{2} - {(2i)}^{2} \} \\ \\ = (81 - 4 {i}^{2} )[/tex]
but i² is -1 [ complex numbers ]
[tex] = \{81 - 4( - 1) \} \\ = 81 + 4 \\ = 85[/tex]
Answer:
[tex](9 + 2i)(9 - 2i) \: \\ this \: can \: be \: wrtten \: as \: \\ {9}^{2} - {2i}^{2} = 81 - 4 \times - 1 \\ = 81 + 4 = 85 \\ then \: 85 + 0i \\ thank \: you[/tex]
.30,36,P,40,44 average is 35 find the value of p
sum of number=30+36+p+40+44=150+p
n=5
average=35
Step-by-step explanation:
average=sum of number÷n
35=150+p÷5
35×5=150+p
175-150=p
25=p
p=25
Answer:
P=25
Step-by-step explanation:
Hi! Let's start with with the average...
First we multiply 35 by the amount of numbers we have
We have 5 including the unidentified
so...
35x5=175
Now since we have 175 we have to add all the other numbers together
30+36+40+44=150
Next we subtract
175-150= 25
P= 25
To check our answer add all of them together
40+30+40+44+25=175
We were right!
Hope this helps! :)
