Answer:
r = 1/11
Step-by-step explanation:
16r-2r = -3r+6r+1
14r = 3r+1 (combine like terms)
11r = 1
r = 1/11
guys pls help with all the steps
Step-by-step explanation:
To solve both questions you will have to use the Pythagoras theorem
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
c being the hypotenuse
so to find AB we say
[tex] {ap}^{2} = {pb}^{2} + {ab}^{2} [/tex]
To make AB the subject of the formula, we take PB over. Therefore:
[tex] {ab}^{2} = {ap}^{2} - {pb}^{2} [/tex]
now we just substitute
[tex] {ab}^{2} = {13}^{2} - {5}^{2} [/tex]
[tex] {ab}^{2} = 169 - 25[/tex]
[tex] {ab}^{2} = 144[/tex]
square root both sides of the equation
[tex]ab = 12[/tex]
We then use the same formula to find AQ(which is a hypotenuse)
[tex] {aq}^{2} = {ab}^{2} + {bq}^{2} [/tex]
[tex] {aq}^{2} = {12}^{2} + {9}^{2} [/tex]
[tex] {aq}^{2} = 144 + 81[/tex]
[tex] {aq}^{2} = 225[/tex]
square root both sides
[tex]aq = 15[/tex]

Answer:
1. 3/8 are female
2. 1/6 ton
3. 1 and 31/40 kg
Step-by-step explanation:
1. 5/8-male, 8/8 - 5/8 = 3/8
2. 2/15 + 3/15 = 5/15, 5/15 = 1/3, 1/3 = 10/30, (1/2 = 15/30) 15 - 10 = 5, 5/30 = 1/6
3. 7/8 + 9/10 = 71/40
Answer:
Step-by-step explanation:
1) 5/8 of the staff is male, 5/12 of the staff works part time
the question askes what fraction of the workforce is female
if 5/8ths is male than the other 3/8ths are female
3/8 of the staff is female
2) how much food was fed at night
2/15 + (2/15 + 1/15) + x = 1/2
2/15 + (3/15) + x = 1/2
5/15 + x = 1/2
1/3 + x = 1/2
x = 1/6
1/6th of a ton was fed at night
3)
just add them
7/8 + 9/10 = 71/40 or 1 31/40
Solve for x using common denominators. 3 over the quantity 5 times the binomial x minus 4 equals x over the quantity x minus 4 −5 over 3 5 over 3 −3 over 5 3 over 5
Answer:
(d) 3/5
Step-by-step explanation:
The equation ...
[tex]\dfrac{3}{5(x-4)} =\dfrac{x}{x-4}[/tex]
can be rewritten so that each side has the same denominator. Then the solution can be found by equating the numerators.
[tex]\dfrac{3/5}{x-4} =\dfrac{x}{x-4}\\\\\boxed{\dfrac{3}{5} =x}[/tex]
_____
Additional comment
"Equating the numerators" is equivalent to multiplying both sides by the common denominator. Of course, any value of the variable that makes the denominator zero is excluded from the solution set.

Question reads….
“ A [PRODUCT] of [a NUMBER] & 6 [is] 26”
RANDOM:
• Product is multiply/multiplication
• A number is unknown so we will label it as “n”
• 6 stays the same because nothing happened to it
• 26 is BEHIND the equal sign but nothing happens to it because nothing is being compared to it

Well I'm assuming these 2 triangles are similar
Then
3:1=36:x
x=12
Answer:
Option D
Step-by-step explanation:
Since they are in proportion. So,
27 : 36 :: 9 : x
27 × x = 36 × 9
x = 36 × 9/27
x = 12 × 1
x = 12

What is the median of the following data values?
10, 11, 12, 15, 19, 24, 27, 29, 33, 38
Answer:
21.5
Step-by-step explanation:
Make sure they are in order.
A median is basically (or literally) the number in the middle of the data set.
In this case, it is 19 and 24. To get the middle number, you have to:
Add the two numbers and divide them by 2.
19 + 24 = 43
43/2 = 21.5

Simplify 30 ÷3 of [37-{30÷(13-20+12)}-26]
Explanation:
30 ÷3 of [37-{30÷(13-20+12)}-26]
= 30÷3 × [37-{30÷(25-20)}-26]
= 30÷3 × [ 37-{30÷(5)}-26]
= 30÷ 3 × [37-{30÷5}-26]
= 30÷3 × [ 37 - {6}-26]
= 30÷3 × [ 37-6 - 26]
= 30÷3 × [ 37 - 32]
= 30÷3 × [5]
= 30÷3 ×5
= 30÷15

The midpoint of \overline{\text{AB}} AB is M(0, -3)M(0,−3). If the coordinates of AA are (2, -5)(2,−5), what are the coordinates of BB?
The formating kinda screwed up
Using the mid-point concept, it is found that the coordinates of B are (-2, -1).
The mid-point of two points is the mean of the coordinates of each point.In this problem:
The points are: A(2, -5) and B(x,y).The mid-point is (0, -3).Applying the concept for both the x and y-coordinates, we have that:
[tex]\frac{x + 2}{2} = 0[/tex]
[tex]x + 2 = 0[/tex]
[tex]x = -2[/tex]
[tex]\frac{-5 + y}{2} = -3[/tex]
[tex]-5 + y = -6[/tex]
[tex]y = -1[/tex]
