Answer:
[tex]m=\frac{15}{8}[/tex]
Step-by-step explanation:
[tex]-6\left(1-m\right)=9-2m[/tex]
[tex]-6(1-m)=-6+6m[/tex]
[tex]-6+6m=9-2m[/tex]
Add 6 to both sides:-
[tex]-6+6m+6=9-2m+6[/tex]
[tex]6m=-2m+15[/tex]
Now, add 2m to both sides:-
[tex]6m+2m=-2m+15+2m[/tex]
Divide both sides by 8:-

One type of fabric costs $31.25 for 5 square yards. Another type of fabric costs $71.50 for 11
square yards. Is the relationship between the number of square yards and the cost
proportional between the two types of fabric?
Answer:
as ratio of two type of fabric is different .
hence, the relationship between the number of square yards and the cost
is not proportional between the two types of fabric
Step-by-step explanation:
For a relation to be proportional
a:b = c:d
in other form
a/b = c/d
______________________________________________
Ratio for first type of fabric
cost of fabric/ area of fabric = 31.25/5 = 6.25
Ratio for other type of fabric
cost of fabric/ area of fabric = 71.50/11 = 6.5
as ratio of two type of fabric is different .
hence, the relationship between the number of square yards and the cost
is not proportional between the two types of fabric

Mia’s house and her aunt’s house are 15.4 inches apart on the map. If every 4 inches on the map represents 10 miles, what is the actual distance from Mia’s house to her aunt’s house, to the nearest tenth of a mile? 2.6 6.2 38.5 61.6
Answer:
38.5 miles
Step-by-step explanation:
We know that the distance between Mia's house and her aunt's house is 15.4 inches apart.
We also know that every 4 inches on the map represent 10 miles.
4 inches = 10 miles
Divide :
1 inch = 2.5 miles
Multiply the shown distance in the question by the amount of miles per inch
15.4 * 2.5
= 38.5 miles in total.

Practice Writing Composite Functions Given: f(x) = x - 7 and h(x) = 2x + 3 Write the rule for h(f(x)).
Answer:
h(f(x)) = 2x - 11Step-by-step explanation:
f(x) = x - 7
h(x) = 2x + 3
To find h(f(x)) substitute f(x) into h(x) that's replace every x in h(x) by f(x)
That's
h(f(x)) = 2(x - 7) + 3
h(f(x)) = 2x - 14 + 3
We have the final answer as
h(f(x)) = 2x - 11Hope this helps you

Answer:
:
"(100 + 3) (100 + 7)
Now, by using identity
(x + a) (x + b) = x² + (a+b)*x + ab
So,
x = 100 , a = 3 , b = 7
= (100)² + (3+7)*100 + (3*7)
= 10000 + 1000 + 21
= 11021
.
(110 - 7) (110 - 3)
by using identity
(x + a) (x + b) = x² + (a+b)*x + ab
So,
x = 100 , a = (-7) , b = (-3)
= (110)² + { (-7) + (-3) }*110 + {(-7)*(-3)}
= 12100 + (-10)*110 + 21
= 21200 - 1100 + 21

= (90)² + (5+6)*90 + (5*6)
= 8100 + 990 + 30
= 9120
.
(100 - 5) (100 - 4)
by using identity
(x + a) (x + b) = x² + (a+b)*x + ab
So,
x = 100 , a = (-5) , b = (-4)
= (100)² + { (-5) + (-4) }*100 + 20
= 10000 + (-9)*100 + 20

(b) In a group of 140 people, 74 like tea, 104 like milk and each person likes at least one of the two drinks.
How many people like both tea and milk?
(ii) How many people like tea only?
(iii) How many people like milk only?
Answer:
How many people like both drinks?
To find the overlap, we can do (104 + 74) - 140 = 38.
How many people like tea only?
To find this, we can do 74 - 38 = 36.
How many people like milk only?
To find this, we can do 104 - 38 = 66.
Answer:
Step-by-step explanation:
A = Number of people who likes tea
B = Number of people who likes milk
Total people = n(A U B) = 140
(i) n(AUB) = n(A) + n(B) - n(A ∩B)
n(A∩B) = n(A) + n(B) - n(A ∪B)
n(A∩B) = 74 + 104 - 140
= 178 - 140
n(A∩B) = 38
Number of people who likes both tea and milk = 38
(ii)Number of people who likes tea only = n(A) - n(A∩B)
= 74 - 38
= 36
(iii) Number of people who likes milk only = n(B) -n(A∩B)
= 104 - 38
= 66
*NEED AN ANSWER ASAP* Find x+y given the angle measures in trapezoid EFGH below.
Answer: x + y = 150
Explanation
y - 65 = 110
y = 110 + 65 (Alternate Interior)
y = 175
y - 65 = 110
∠FGH = 70
70+55+x+45+110 = 360 (sum of angles of a quadilateral is 360)
x + 280 = 360
x = 360 - 280
x = 80
So
x + y = 70 + 80
= 150

What is the angle of C?
Answer:
50°

suppose we want to choose 6 letters without replacement from 13 distinct letters. A) how many ways can this be done if order does not matter? B) how many ways can this be done if order of choices matters
Answer: A) 1716 B) 1235520
Step-by-step explanation:
If order doesn't matter , then we use combinations, where the number of combinations of selecting r things from n is given by :-[tex]^nC_r=\dfrac{n!}{r!(n-r)!}[/tex]
If order matters , then we use permutations, where the number of permutations of selecting r things from n is given by :-[tex]^nP_r=\dfrac{n!}{(n-r)!}[/tex]
Given, Total distinct letters = 13
To choose = 6 letters
A) Number of ways to choose (if order does not matter)=[tex]^{13}C_6[/tex]
[tex]=\dfrac{13!}{6!7!}=\dfrac{13\times12\times11\times10\times9\times8\times7!}{(720)\times 7!}\\\\= $$1716[/tex]
B) Number of ways to choose (if order matters)=[tex]^{13}P_6[/tex]
[tex]=\dfrac{13!}{7!}=\dfrac{13\times12\times11\times10\times9\times8\times7!} 7!}\\\\= $$1235520[/tex]
Hence, A) 1716 B) 1235520
Let's see what it would take to win that trip to Hawaii.
Remember that you think you'll respond to 12 questions and hope to score 600 points to win,
although it's possible to score even more points or many fewer (including negative scores!) on
the show.
Here are the equations you wrote to model your winning scenario:
x+y=12
100x - 200y = 600
Are the boundaries of the first equation viable in the second equation? What does this
suggest about your plan to score 600 points?
Select the two correct statements.
Answer:
A and D choices (Plato)
Step-by-step explanation:
The upper boundary of the first equation is at x = 12, y = 0. With these values, this is the second equation:
100(12) − 200(0) = 1,200.
The lower boundary of the first equation is at x = 0, y = 12. With these values, this is the second equation:
100(0) − 200(12) = -2,400.
Both of these scores are possible in the game, so they are both viable.
Because the upper boundary is greater than 600, it suggests that you can still score 600 points and win the game even if you get one or two of the questions incorrect.
In fact, you could give 10 correct and 2 incorrect answers to score 600 points and still beat the champion, Kimberly, assuming she answers 15 correct and 5 incorrect to score 500 points.

the sum of 48 and itself its half and half of the hal is added to 18
Answer:
150
Step-by-step explanation:
We are carrying out Addition
a) The sum of 48 and itself
= 48 + 48 = 96
b) Its half and half of the half
96 + (1/2 × 48) + (1/2 ×( 1/2 × 48)
= 96 + 24 +(1/2 × 24)
= 96 + 24 + 12
= 132
c) is added to 18
= 132 + 18
= 150
Therefore, the sum of 48 and itself, its half and half of the half is added to 18 is 150
The sum of 48 and itself its half and half of the half is added to 18 is 150.
Given, we have a number 48.
We have to find the sum of 48 and itself its half and half of the half is added to 18.
So, the half of the 48 is 24 and half of the half becomes 12.
Now the equation becomes,
[tex]48+48+24+12+18=150[/tex]
Hence the required sum is 150.

What is the measure of the other acute angle? b. What is the height of the tree? c. You are standing at the end of the tree's shadow and want to take a picture of the tree but your camera can only focus at distance less than 500 feet. When you hold the camera to take the picture it is 5 feet above the ground. What is the distance from the end of the shadow to the top of the tree? d. Can you take a clear picture of the top of the tree from where you are standing?

Demerol 45mg and atropine 400mcg/ml give how much per ml to total volume to inject demerol contains 50mg/ml, atropine contains 400mcg/ml how much volume to inject
Answer:
Volume injected = 1.65 ml
Step-by-step explanation:
mass of Demerol =45 mg.
density of pre-filled in syringe = 50 mg/ml
Volume = 45/50 = 0.9 ml
For atropine mass = 0.3 mg
density= 400 mcg/ml [ Note : 1 mcg = 0.001 mg]
volume filled = 0.3/400(0.001) = 0.75 ml
So, the total volume filled = 0.75+0.9 = 1.65 ml
