help please!
A -1.8
B -1.6
C -1.5
D -1.3
Answer:
B) -1.6
Step-by-step explanation:
As you can see there is a pattern of 5 dashes, meaning that each dash would increase by 0.2
So, the dash behind the -1 equals to -1.2. The one two dashes behind the -1 would be -1.4. Sequentially, the dash E would be -1.6.
Am I correct?
Which function represents the inverse of function f?
Here you are multiplying by 3 then adding 5. When doing the inverse, you would do the opposite.
Start with x. then subtract by 5. Itvwould be x-5.
Then divide by 3. So it would be (x-5)/3 which is 1/3x-5/3 which is D

b) 1.875 quarts of grape
Step-by-step explanation:
Question 2 Fill in the blanks to complete the sentence.
A recipe for sparkling grape juice calls for 1 1/2 quarts of sparkling water and 3/4 quart of grape juice.
a. How much sparkling water would you need to mix with 9 quarts of grape juice?
3/4 quarts of grape = 1 1/2 quarts sparkling water
9 quarts of grape = x
x = (9 × 1 1/2) ÷ 3/4
x = (9 × 3/2) × 4/3
x = 27/2 × 4/3
x = 18 quarts of sparking water
b. How much grape juice would you need to mix with 15/4 quarts of sparkling water?
1 1/2 quarts of sparkling water = 3/4 quarts of grape
1 5/4 quarts of sparkling water = x
x = (3/4 × 15/4 ) ÷ 1 1/2
x = (0.75 × 3.75 ) ÷ 1.5
x = 1.875 quarts of grape
c. How much of each ingredient would you need to make 100 quarts of punch?
Round your answer to the nearest whole quart. sparkling water: quarts grape juice: quarts

Given:
[tex]m\angle L=m\angle Z=70^\circ[/tex]
[tex]m\angle N=m\angle Y=90^\circ[/tex]
To find:
The value of [tex]m\angle 1[/tex].
Solution:
In triangle XYZ,
[tex]m\angle Y=m\angle N=90^\circ[/tex] (Given)
[tex]m\angle Z=m\angle L=70^\circ[/tex] (Given)
[tex]m\angle X+m\angle Y+m\angle Z=180^\circ[/tex] [Angle sum property]
[tex]m\angle 1+90^\circ+70^\circ=180^\circ[/tex]
[tex]m\angle 1+160^\circ=180^\circ[/tex]
[tex]m\angle 1=180^\circ-160^\circ[/tex]
[tex]m\angle 1=20^\circ[/tex]
Therefore, the [tex]m\angle 1[/tex] is 20°.

5. (1, 2), (2, 5), (2, 1) (4, 5) No
Step-by-step explanation:
If you see the same x-coordinate more than once in a relation, then that relation is not a function.
1. (1, 3), (2, 5), (2, 7) (4,9) The 2 is used more than once as a x-coordinate. Not a function.
2. (1, 3), (2, 5), (3, 7) (4,9) All x-coordinates are different. Function.
3. (1, 3), (1,5), (1, 7) (4, 9) The 1 is used more than once as an x-coordinate. Not a function.
4. (1,3), (2, 3), (3, 3) (4, 3) All x-coordinates are different. Function.
5. (1, 2), (2, 5), (2, 1) (4, 5) The 2 is used more than once as a x-coordinate. Not a function.
A baker regularly uses flour to make pastries for the bakery at the beginning of the month of the Baker has a 25 pound bag of flour. Each week she uses 5 3/5 pounds of flour write an expression to represent the change in weight of the bag of flour over four weeks
Answer:
At the beginning, she has 25lb of flour.
Each week, she ses (5 + 3/5) pounds of flour.
Then after the first week, she has a total of:
W(1) = 25lb - (5 + 3/5)lb
After another week, she has:
W(2) = 25lb - (5 + 3/5)lb - (5 + 3/5)lb = 25lb - 2*(5 + 3/5)lb
and so on.
if x represents the number of weeks, the equation is:
W(x) = 25lb - x*(5 + 3/5)lb
where x can be {0, 1, 2, 3, 4}
That is the equation that represents the change in the weight for the first four weeks.

Answer: Answer: CB = 7. AC = 5.
Step-by-step explanation:
Well we know that A-B is 7. And this is a right triangle, so the CB will be the same length. So CB = 7.
Now AC.
You divide 45 degrees by 7. And you get five.
So AC = 5 and CB = 7.
The number 19/7 ( a rational or an irrational )
number.
plz answer
Answer:
rational
Step-by-step explanation:
Answer:
Rational number
Step-by-step explanation:
The definition of a rational number is "A number such as -3/7 that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q." The definition of an irrational number is "All the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers." This means 19/7, and all improper fractions, are rational numbers.
