The slope is 1/2.
If you pick two points and count the rise over run (see picture below), you might get 1/2 or 2/4 or 3/6. But 3/6 and 2/4 reduce down to 1/2.
A chemical company makes two brands of antifreeze. The first brand is 40% pure antifreeze, and the second brand is 60% pure antifreeze. In order to obtain 180 gallons of a mixture that contains 55% pure antifreeze, how many gallons of each brand of antifreeze must be used?
First brand =
Second Brand=
Answer:
Step-by-step explanation:
Let x be the portion of 60%
180 - x is the portion of 40%
0.60x + 0.40(180 - x) = 0.55(180)
0.60x + 72 - 0.40x = 99
0.20x = 27
x = 135
180 - 135 = 45
First brand = 45 gallons of 40%
Second Brand = 135 gallons of 60%

The ratio of the number of Marbles zali had to the number of marbles muthu had was 3 : 4 muthu gave half of his marbles to zali what was the new ratio of the number of marbles zali had to the number of marbles muthu had ?
Using the given ratio 3:4, Zali has 3 marbles and Muthu has 4 marbles.
If Muthu gives half of his marbles to Zali, Muthu would have 2 marbles (4/2 = 2) and Zali would have 5 ( 3+2 = 5). The ratio would now be 5:2

need help rn please?/..Thank you. Multiple step equation
Answer:
The answer (using BEDMAS) is 27
Step-by-step explanation:
The equation 9 x [(18+2) ÷ 5 - 1] is solved using BEDMAS or PEDMAS
First solve the smaller bracket
18 + 2 = 20
So then it becomes 9 x [20 ÷ 5 - 1]
Do the division inside the bracket next
20 ÷ 5 = 4
Then it becomes 9 x [4 - 1]
Do then subtraction within the bracket
4 - 1 = 3
Then it becomes 9 x 3
Finally solve 9 x 3 which equals 27

m ∠APQ = m ∠RQP = 62° If parallel lines, then alternate interior angle =
m ∠DRP + m ∠PRQ = 180° These angles form a linear pair which = 180°
115° + m ∠PRQ = 180° Substitution
m ∠PRQ = 65° Subtraction
m Δ QPR = 180° Definition of triangle
m Δ QPR = m ∠PQR + m ∠QPR + m ∠PRQ the sum of the angles of triangle
180° = 62° + x + 65°
180 = 127 + x
53 = x

Is 1.572735 rational?
Answer:
yes
Step-by-step explanation:
it is rational
Answer:
Yes
Step-by-step explanation:
To write 1.572735 as a fraction you have to write 1.572735 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
1.572735 = 1.572735/1 = 15.72735/10 = 157.2735/100 = 1572.735/1000 = 15727.35/10000 = 157273.5/100000 = 1572735/1000000
And finally we have:
1.572735 as a fraction equals 1572735/1000000
And since there is a ratio (a proper fraction) number, it is rational.
Hannah has a chicken coop with six hens. Let X represent the total number of eggs the hens lay on a random day. The distribution for X is given in the table.
What is the probability that the hens lay a total of two eggs?
0.05
0.07
0.12
0.93
Answer:
0.07
Step-by-step explanation:
I'm sorry if its wrong
The probability that the hens lay a total of two eggs is 0.07. Therefore, the option B is the correct answer.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
Given that, Hannah has a chicken coop with six hens.
Let X represent the total number of eggs the hens lay on a random day.
Let the probability that the hens lay a total of two eggs be y
From the table,
X=0.02+0.03+y+0.12+0.30+0.28+0.18
We know that, the total of probability should be 1.
Now, 1=0.02+0.03+y+0.12+0.30+0.28+0.18
1=0.93+y
y=1-0.93
y=0.07
Therefore, the option B is the correct answer.

9514 1404 393
Answer:
a) k = 2/5
b) y = 2/5x
c) y = 2 3/5
Step-by-step explanation:
a)The proportional relation is described by the equation ...
y = kx . . . . . . k is the constant of proportionality
The value of k can be found by dividing the equation by x:
y/x = k = (2 1/4)/(5 5/8) = (9/4)/(45/8) = 18/45
k = 2/5
__
b)As above, the equation is ...
y = kx
y = 2/5x
__
c)Using 6.5 for x, we have ...
y = (2/5)(6.5) = 2.6 = 2 3/5

The perimeter of a rectangle is 94 yards. The width is 23yards less than the length. Find the length and the
width of the rectangle.
Answer:
The length = 35 ; The width = 12
Step-by-step explanation:
Perimeter = 2L + 2W
Length = x
Width = x - 23
94 = 2(x) + 2(x - 23)
94 = 2x + 2x - 46
94 = 4x - 46
94 + 46 = 4x
140 = 4x
140/4 = x
35 = x The length = 35; The width = (35 - 23) = 12

Here, '5' & 'a' are the common factors. So factor them out.

Myra incorrectly put 'a' inside the bracket which is wrong because 'a' is a common factor too along with 5.
