Step-by-step explanation:

Answer:

a) 18 quarts of sparkling water

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

Answer:

3589.85763 meters

Step-by-step explanation:

Essentially, we must have e^(-0.00012h) = 0.65 since 0.65 = 65%

Taking natural log of both sides, we get

-0.00012h = -0.430782916

0.00012h = 0.430782916

h = 3589.85763

Answer: L = R (The second one)

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

got it right

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°.

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.

Answer:

$25.58

Step-by-step explanation:

39 * 0.45= 17.55

43.13 - 17.55= $25.58

Answer:

Yes

Step-by-step explanation:

they are both equal to 3:4

21:28 can be reduced by 7

21/7=3

28/7=4

and 6:8 can be reduced by 2

6/2=3

8/2=4

Answer:

1

Step-by-step explanation:

2+0=2 so 2 times 1/2 is 1

Answer:

B. 4

Step-by-step explanation:

Hypotenuse (h) = 5

base (b) = 3

perpendicular (p) = a = ?

We know by using Pythagoras theorem we get

p = √( h² - b²)

= √ ( 5² - 3²)

= √ (25 - 9)

= √16

= 4

Hope it will help :)

Answer:

B

Step-by-step explanation:

B is the right answer....you can use pythagoras theorem to get that i.e a=√5^2-3^2

Answer:

7= 2 4/5         8=2/21           9= 6 3/7          10= 1/6            11= 7/5           12=77/90

Step-by-step explanation:

3 1/5= 16/5-2/5=14/5 which equals to the same thing to 2 4/5

5/3= 35/21

11/7= 33/21

35/21-33/21= 2/21

3 3/4=15/4 times 12/7 straight ahead which is 180/28 equals to the same thing as 45/7 = 6 3/7

1/5 times 7/1 so u flip it over as u can see which is 7/5

2 1/5= 11/5    2 4/7= 18/7       11/5 times 7/18=77/90

Answer:

Team Nara collected more water

1.402 > 1.045

so team nara wins

Team Narra is collected more amount of water than Team Mahogany and this can be determined by using the given data.

Given :

The following steps can be used to determine which team collected more amount of water in a cup:

Step 1 - Remember that the amount of water collected by Team Narra is 1.402 liters.

Step 2 - Also remember that the amount of water collected by Team Mahogany is 1.045 liters.

Step 3 - Now, compare both quantities of water.

1.045 < 1.402

So, according to the given data Team Narra is collected more amount of water than Team Mahogany.

Step-by-step explanation:

5 hours is double 2.5 hours so double 200 to get 400

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.
