Answer:

2/10

Step-by-step explanation:

Ms. Geiger made 100 cupcakes.

a) Number of chocolate

60/100 were chocolate

= 60/100 × 100 = 60 chocolate cup cakes

b) Number of vanilla

2/10 were vanilla

Hence:

2/10 × 100 = 20 vanilla cup cakes

c) the rest were red velvet.

Number rod red velvet = 100 - (60 + 20)

= 100 - 80

= 20 velvet cupcakes

What fraction of the cupcakes were red velvet?

Converting to fraction

Number of velvet cupcakes/Total number of cakes

= 20/100

= 2/10

Answer:

Answer 3 (1.89m - 3)

Step-by-step explanation:

Since we know that the price per song is $1.89, that is going to be the part of the equation that goes with the variable.

Since she has a 3 dollar credit, this will reduce the cost of whatever amount of songs she is buying by 3 dollars, which means the second part of the equation is -3. You have your answer, 1.89m - 3.

Answer:

[tex]25 \: {units}^{2} [/tex]

Step-by-step explanation:

[tex] \frac{(10 \times 5)}{2} = 25[/tex]

y = [tex]\frac{-5}{4}[/tex]x + 3

As shown in the graph, the line is a straight line. Therefore, the general equation of a straight line can be employed to derive the equation of the line.

The general equation of a straight line is given by:

y = mx + c or            -------------(i)

y - y₁ = m(x - x₁)        -----------------(ii)

Where;

y₁ is the value of a point on the y-axis

x₁ is the value of the same point on the x-axis

m is the slope of the line

c is the y-intercept of the line.

Equation (i) is the slope-intercept form of a line

Steps:

(i) Pick any two points (x₁, y₁) and (x₂, y₂) on the line.

In this case, let;

(x₁, y₁) = (0, 3)

(x₂, y₂) = (4, -2)

(ii) With the chosen points, calculate the slope m given by;

m = [tex]\frac{y_2 - y_1}{x_2-x_1}[/tex]

m = [tex]\frac{-2-3}{4-0}[/tex]

m = [tex]\frac{-5}{4}[/tex]

(iii) Substitute the first point (x₁, y₁) = (0, 3) and m = [tex]\frac{-5}{4}[/tex] into equation (ii) as follows;

y - 3 = [tex]\frac{-5}{4}[/tex](x - 0)

(iv) Solve for y from (iii)

y - 3 = [tex]\frac{-5}{4}[/tex]x

y = [tex]\frac{-5}{4}[/tex]x + 3 [This is the slope intercept form of the line]

Where the slope is [tex]\frac{-5}{4}[/tex] and the intercept is 3

Answer:

11 and 12

Step-by-step explanation:

The two numbers will be called x and y. The sum of x and y is 23 and the difference is 1.

x + y = 23  

x - y = 1

Add the equations together

x + y + x - y = 23 + 1

2x = 24

x = 12

y = x - 1

y = 11

Answer:

The value of x is 70

Step-by-step explanation:

Here, we want to find the value of x

To do this, we are going to use one of the circle tangent relationships

we have this as;

24 = (118-x)/2

2(24) = 118-x

48 = 118-x

x = 118-48

x = 70

Answer:

75.4m²

Step-by-step explanation:

The shape shown is a cylinder

The volume of a cylinder can be calculated using this formula:

[tex]V=\pi r^2h[/tex]

where r = radius and h = height

The cylinder shown has a radius of 2m and a height of 6m

Using this information we plug in the values into the formula

[tex]V=\pi 2^26\\2^2=4\\4\pi =12.56637\\12.56637*6=75.39822[/tex]

So the area of the cylinder is 75.39822

Our final step is to round to the nearest hundredth

The final answer would be 75.4m²

natural log = ln= log base e = logₑ

Since Darien is discounting the prices by 20%, the new price will be 80% of the original price, or 0.8 times the original price

Step-by-step explanation:

Step-by-step explanation:

350/5=70 liters X 2 drops for every 5 liters=140 drops needed for the whole tank.

Since 1 cupful contains 40 drops, the we have this:

140 drops needed for the full tank/40 drops contained in one cup, or,

140/40=3 1/2=3.5 number of cupfuls needed for the full tank.

hopefully this helps

Answer:

Phone 1 will allow Ellie to talk the longest

Step-by-step explanation:

Phone 1:

     (0.10x) + 6 = y

(0.10x) + 6 - 6 = 22 - 6

     0.10/0.10x = 16/0.10

                    x = 160 minutes

Phone 2:

      (0.25x) + 5 = y

(0.25x) + 5 - 5  = 22 - 5

     0.25/0.25x = 17/0.25

                      x = 68 minutes

Answer:

Step-by-step explanation:

just took the edge.

The area of the sector is 250 units². Therefore, the correct option is option A among all the given options.

A circle's sector is a pie-shaped portion made up of the arc and its two radii. At both ends of the arc, when a section of the circle's circumference (also called as an arc) and two of its radii meet, a sector is produced. A sector of such a circle resembles a piece of pizza or a pie in shape.

A circle ranks among the most ideal shapes in geometry. The simplest geometric shape is that of a circle's sector. It has a number of its own components. such as sector, segmentation, circumference, segment, and diameter. The area of the sector is 250 units².

Therefore, the correct option is option A.
