Cindy dissolves 19 1 /4 grams of drink mix in 1 3 /4 ounces of water. What is the unit rate in grams of drink mix per ounce of water?

Answers

Answer:

There are 11 g of drink mix for every ounce of water.

Step-by-step explanation:

In order to calculate the unit rate in grams of drink mix for ounces of water of any type of drink, we need to divide the mass of drink mix in grams by the mass of water in ounces. In this case there are mixed fractions, we will first convert them to fractions, to do that we sum the fraction part with the integer one.

[tex]mix = 19 + \frac{1}{4}\\\\mix = \frac{77}{4}[/tex]

[tex]water = 1 + \frac{3}{4}\\\\water = \frac{7}{4}[/tex]

The rate is:

[tex]rate = \frac{mix}{water}\\\\rate = \frac{\frac{77}{4}}{\frac{7}{4}}\\\\rate = \frac{77}{7}\\\\rate = 11[/tex]

What is: 1x2x3x4x5x6x7x8x9x10?

Answers

the answer is 3628800    

The solution to the equation "1x2x3x4x5x6x7x8x9x10" is 362,880.

How to find the multiplication?

This is a factorial, which is the product of all the positive integers less than or equal to a given number. In this case, the factorial is 10!, which is the product of all the positive integers less than or equal to 10.

To calculate 10!, use the following formula:

n! = n × (n - 1) × (n - 2) × ... × (3) × (2) × (1)

where n is the number to be taking the factorial of.

In this case, n = 10, so:

10! = 10 × (9) × (8) × (7) × (6) × (5) × (4) × (3) × (2) × (1) = 362,880

Therefore, 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 = 362,880.

in each diagram the line BD bisects angle ABC. Find the measure of angle ABC​

Answers

Answer:

∠ ABC = 134°

Step-by-step explanation:

Given tat CD bisects ∠ ABC then

∠ DBC = ∠ ABD , substitute values

x - 33 = [tex]\frac{x}{2}[/tex] + 17 ( multiply through by 2 to clear the fraction )

2x - 66 = x + 34 ( subtract x from both sides )

x - 66 = 34 ( add 66 to both sides )

x = 100

Thus

∠ DBC = ∠ ABD = x - 33 = 100 - 33 = 67°

Hence

∠ ABC = ∠ DBC + ∠ ABD = 67° + 67° = 134°

The answer is 1846.32 units³.

Step-by-step explanation:

Given that the base of a cone is a circle so the area of circle is A = πr². You have to substitute the following values into the formula :

[tex]v = \frac{1}{3} \times \pi \times {r}^{2} \times h[/tex]

Solve for x: 6x + 5 = 4x + 51

Answers

Answer:

x=23

Step-by-step explanation:

6x + 5 = 4x + 51

Take away 4x from both sides

2x + 5 = 51

Take away 5 from both sides

2x = 46

Divide both sides by 2

x=23

Answer: x=23

explanation: First thing you need to do is rearrange the equation so that like-terms are together. To avoid negative numbers, subtract 5 from both sides of the equation (subtraction property of equality), and subtract 4x from both sides (subtraction property of equality). You're equation would then be 2x=46. Divide both sides (division property of equality) by 2 to isolate your variable of x. You'll be left with a final answer of x=23.

The equation of the line in slope-intercept form is: A. y = -2x + 3.

What is the Equation of a Line in Slope-intercept Form?Equation in slope-intercept form is y = mx + b.b is the y-intercept.m is the slope of the line.

Thus, find the slope (m):

Slope (m) = change in y/change in x = -2/1 = -2

y-intercept (b) = point on the y-axis where the line intersects the y-axis = 3.

Therefore, substitute b = 3 and m = 2 into y = mx + b:

y = -2x + 3

Therefore, the equation of the line in slope-intercept form is: A. y = -2x + 3.

Answers

Answer:

[tex]x =6[/tex]

Step-by-step explanation:

Given

Bisected Sector AB;

AP = 15x - 11

PB = 9x + 25

Required

Find x

When a sector is bisected, it means the sector is divided equally into two;

Hence [tex]AP = PB[/tex]

This gives

[tex]15x - 11 = 9x + 25[/tex]

Add 11 to both sides

[tex]15x - 11 + 11 = 9x + 25 + 11[/tex]

[tex]15x = 9x + 25 + 11[/tex]

[tex]15x = 9x + 36[/tex]

Subtract 9x from both sides

[tex]15x - 9x = 9x + 36 - 9x[/tex]

[tex]15x - 9x = 9x - 9x + 36[/tex]

[tex]6x = 36[/tex]

Divide through by 6

[tex]\frac{6x}{6} = \frac{36}{6}[/tex]

[tex]x = \frac{36}{6}[/tex]

[tex]x =6[/tex]

Hence, the value of x is 6

Answer:

x=6
