Arianna needs 3/4 cup of flour to bake a batch of cupcakes. she has 1/2 cup of flour. what fraction of a batch can Arianna bake?

Answers

Answer:

She can bake 3/8 of a batch of cupcakes.

Step-by-step explanation:

If she only has 1/2 of the flour and you are trying to find the fraction of a batch she can make, you are essentially trying to figure out what is 1/2 of 3/4, which is basically just multiplying 1/2 by 3/4. This would get you the answer of 3/8. Hope this helps:)

d= 4/5a + h solve for a

Answers

Answer:

5/4d - 5/4h = a or a = 5d-5h/4

Step-by-step explanation:

d = 4/5a + h

~Subtract h to both sides

d - h = 4/5a

~Multiply 5/4 to both sides

5/4d - 5/4h = a or a = 5d-5h/4

-5 ( x - 1 ) - x + 1 = -18

Answers

Answer:

x=4

Step-by-step explanation:

-5x+5-x+1=-18

combine like terms

-6x+6=-18

subtract 6 from both sides

-6x=-24

divide both sides by -6

x=4

Answer:

x=-4

Step-by-step explanation:

-5 ( x - 1 ) - x + 1 = -18

-5x+5-x+1=-18

6x+6=-18 <- -6 from both sides

6x=-24 <- divide 6 by both sides

x=-4

Helena is thinking of a number. That number raised to the third power is 100 greater than when it is raised to the second number. What is the number Helena thinking about

Answers

Answer:

Step-by-step explanation:

Let the number = x

x^3 = x^2 + 100

x^3 - x^2 +0x - 100 =0

a = 1

b = - 1

c = 0

d = -100

My calculator solves these kinds of questions. The answer is

x1 = 5 Which we should be able to get without a special calculator

x2=-2+4i

x3 = - 2 - 4i

I doubt you need anything more than 5. If she is thinking of the complex numbers, she should be in a special class for people who think about such things

I got the -1/2 slope Bc you go over 1 and down 2. And the 8 is the yintercept where the line crosses the y-axis

Determine whether or not the relation is a function. Please help asap

Answers

Answer:

A function can have many x values for a given y value and still be a function but it cannot have many y values for a given x value. You can easily test this by graphing the equation and doing the vertical line test by seeing if a vertical line will intersect the graph only once at all x values, if it passes it is a function. In short what you have here is a function

Step-by-step explanation:

The island of Martinique has received $32000 for hurricane relief efforts. The island’s goal is to fundraise more than y dollars for aide by the end of the month. They receive donations of $4500 each day. Write an inequality that represents this situation, where x is the number of days.

Answers

Answer:

y=4500x+32000

Step-by-step explanation:

If they are increasing at a constant rate of 4500 then that is the coefficient of x, and if they received a 32000$ donation then that is the y-intercept so you add that to 4500x to get this equation.

i need help i dont really understand what they mean by y=-x+7 please help me ty and no links!!

Answers

Answer:

Step-by-step explanation:

y = -x + 7 is a linear equation in slope-intercept form, y = mx + b.

The slope (m) measures the unit changes in the output (y ) for each one-unit change in the input (x) value.

b = the y-ccordinate of the y-intercept, (0, b). The y-coordinate, b, is what you will use for the slope-intercept form. The y-intercept is the point on the line where it crosses the y-axis.

Graphing y = - x + 7:

To graph y = -x + 7, use the slope, m = -1 (down 1 unit, run 1 unit), and the y-intercept, (0,7) to plot points on the graph to connect a line with.

Vertical Line (Definition):

The equation, x = 3 represents a vertical line with an undefined slope. A vertical line has undefined slope because all points the line have the same x-coordinate. Since any two points on a vertical line have the same x-coordinate, slope cannot be computed as using the slope formula, m = (y₂ - y₁)/(x₂ - x₁), as it will involve a division by zero (which consitutes an undefined operation).

Graphing x = 3:

To graph x = 3, choose any point on the graph that has an x-coordinate of 3, then draw a vertical line from there.

The given equation has a solution that occurs at point (3, 4). Attached is an edited screenshot of the image that you uploaded.

For each parallelogram below, find the values of the missing sides or
angles.

Answers

Answer:

m ∠DCA

m ∠CAD = 56

m ∠CBA = 83°

Step-by-step explanation:

A parallelogram is a polygon with two pairs of parallel lines

m ∠CDA = m ∠CBA = 83° Opposite angles in a parallelogram are =

m ∠CAD = m ∠ACB = 56° CB ║ DA and alternating interior angle are =

m ∠DCA = 180° The sum of the angles in a triangle = 180°

m ∠ADC + m ∠CAD + m ∠DCA = 180 Parts of the triangle

83° + 56° + m ∠DCA = 180 Substitution

139° + m ∠DCA = 180°

m ∠DCA = 180° - 139°

m ∠DCA = 41°
