Answer:

2.7  or 2 7/10.

Step-by-step explanation:

9 * 3/10

= 27 / 10

= 2.7.

For step one, they want you to factor 5,000 into a 5 and ?. To find the missing value, we can divide:

5,000 / 5 = 1,000

So, 1000 goes in the first blank.

For step two, 1,000 also goes in the second blank since the first 2 numbers are being multiplied.

For step three, multiply the last two numbers.

30 * 1000 = 30,000

So, 30000 goes in the last blank.

Best of Luck!

Answer: 30000 goes in the last one

Answer:

height = 142.00 ft

height ≈ 200. 82 ft

height ≈ 245.95 ft

Step-by-step explanation:

The picture below represent the image of the draw bridge. The illustration will form a right angle triangle. The hypotenuse is each half of the drawbridge which is 284 ft long. The opposite side  of the triangle is facing the drawbridge half leg and the adjacent side is horizontal length. This is the side that made the angle with the drawbridge half leg(hypotenuse).

The question ask us to find the height of the drawbridge when it rise which is the opposite sides of the triangle when the angle is 30° , 45° and  60°.

Using SOHCAHTOA principle,

Angle 30°

sin 30° = opposite/hypotenuse

sin 30°  = height/284

cross multiply

height = 0.5 × 284

height = 142.00 ft

Angle 45°

sin 45° = height/284

height = 284 × 0.70710678118

height = 200.818325857

height ≈ 200. 82 ft

Angle 60°

sin 60 = height/284

cross multiply

height = 0.86602540378  × 284

height = 245.951214675

height ≈ 245.95 ft

The question asks about the height a drawbridge rises at different angles. This is a trigonometry problem that can be solved by using the sine of the angle to calculate the height of the bridge when raised. The height corresponds to the 'opposite' side in a right triangle formed by the raised drawbridge.

This question appears to be asking about how high a drawbridge rises based on an angle, x, which is a trigonometry problem. Assuming that the drawbridge forms a right triangle when it rises, the height can be calculated using the sine of the angle, x. Sine of x is equal to the opposite side (height of the bridge when it is raised) over the hypotenuse (half of the drawbridge's length).

Applying these trigonometric principles, calculations for each scenario would look like the following:

Answer:

Average speed v = 83.8 km/h

Step-by-step explanation:

Given;

Distance travelled = 95 km

Time taken t = 12.23 - 11.15 = 1 hour 8 minutes

t = 1 + 8/60 hours = 1.133 hours.

Average speed v = distance travelled/time taken

substituting the values;

v = 95 km ÷ 1.133 hours

Average speed v = 83.8 km/h

Answer:

Answer:

For this case is the rectangle is dilated a factor of 2.2 we assume that the expansion is in all the dimensions so then the new length and width are:

[tex] L_f = 2.2 L_i= 2.2* 7.5 in = 16.5 in[/tex]

[tex] W_f = 2.2 w_i = 2.2 * 3 in = 6.6 in[/tex]

Step-by-step explanation:

The area of a rectangle is given by [tex] A = L *W[/tex]

For this case is the rectangle is dilated a factor of 2.2 we assume that the expansion is in all the dimensions so then the new length and width are:

[tex] L_f = 2.2 L_i= 2.2* 7.5 in = 16.5 in[/tex]

[tex] W_f = 2.2 w_i = 2.2 * 3 in = 6.6 in[/tex]

And the area would be (2.2)^2 times the initial area since is defined as [tex]A = L_f W_f [/tex]

Answer:

The length and the width of the new rectangle are 16.5 inches and 6.6 inches respectively

Step-by-step explanation:

Given

Shape: Rectangle

[tex]Length = 7.5 inches[/tex]

[tex]Width = 3 inches[/tex]

[tex]Scale factor = 2.2[/tex]

Required

Dimension of the new rectangle

The dimensions of the new rectangle can be solved by multiplying the scale factor by the old dimensions;

This means that

New Length = Scale factor * Old Length

and

New Width = Scale factor * Old Width

Calculating the new length

New Length = Scale factor * Old Length

Substitute 2.2 for scale factor and 7.5 for old length; This gives

[tex]New Length = 2.2 * 7.5 inches[/tex]

[tex]New Length = 16.5 inches[/tex]

Calculating the new width

New Width = Scale factor * Old Width

Substitute 2.2 for scale factor and 3 for old width; This gives

[tex]New Width = 2.2 * 3 inches[/tex]

[tex]New Width= 6.6 inches[/tex]

Hence, the length and the width of the new rectangle are 16.5 inches and 6.6 inches respectively

Answer:

I think the plastic cup are 24

Answer:

70

Step-by-step explanation:

mark = 1    1 times 14 = 14

Brian = 5   5 times 14 = 70

Brian receives 70 sweets, as Mark's 14 sweets represent 1 part of the ratio 1:3:5, indicating that 1 part equals 14 sweets and Brian's 5 parts equal 70 sweets.

Mark, Paul, and Brian share sweets in a ratio of 1:3:5, which means that for every sweet Mark gets, Paul gets 3, and Brian gets 5. Since Mark gets 14 sweets, we can use this information to calculate how many sweets Brian gets. First, let's find out what one 'part' of the ratio is worth by dividing the number of sweets Mark gets by his ratio number:

Mark's sweets (14) / Mark's ratio (1) = 14 sweets per ratio part.

Next, determine Brian's share by multiplying the sweets per ratio part by Brian's ratio number:

Brian's share = sweets per ratio part (14) * Brian's ratio (5) = 70 sweets.

Therefore, Brian gets 70 sweets.

Step-by-step explanation:

A can is a cylinder

V = pi r^2 h

The diameter is 6.4  we want the radius

r = d/2 = 6.4/2 = 3.2

V = 3.14 * (3.2)^ * 12.3

V =395.48928 cm^3

1 cm^3 = 1ml

V = 395.48928 mL

A can of soda has 355 mL

We are over estimating because the can narrows on the ends and the height is actually shorter because the ends do not have volume but are metal to contain the soda.  We also did not take into account the curve in the bottom of a can of soda.

Answer:

395.48928 cm³

40.48928 cm³ greater than an actual can

Step-by-step explanation:

Answer:

The restrictions partly depend on the type of function.

You can’t divide by  0

You can’t take the square (or other even) root of a negative number, as the result will not be a real number.

In what kind of functions would these two issues occur?

the function is a rational function and the denominator is  

0

for some value or values of x,  

f ( x ) = x + 1 2− x

is a rational function

the function is a radical function with an even index (such as a square root), and the radic and can be negative for some value or values of x.  

f ( x ) = √ 7 − x

is a radical function

Answer:28 green and 35 red

Step-by-step explanation:

Given

If there are r red counter and g green counter then

Probability of drawing a green counter is [tex]P(g)=\frac{4}{9}[/tex]

and [tex]P(g)=\frac{\text{No of g counter}}{\text{Total no of counter}}[/tex]

Thus [tex]\frac{\text{No of g counter}}{\text{Total no of counter}}=\frac{4}{9}[/tex]

[tex]\frac{g}{g+r}=\frac{4}{9}[/tex]

[tex]\Rightarrow 9g=4g+4r[/tex]

[tex]\Rightarrow 5g=4r\quad \ldots(i)[/tex]

Also if 4 red and 2 green counter is added the probability of drawing a green counter is

[tex]P(g)=\frac{10}{23}=\frac{\text{No of g counter}}{\text{Total no of counter}}[/tex]

[tex]\Rightarrow \frac{10}{23}=\frac{g+2}{g+2+r+4}[/tex]

[tex]\Rightarrow \frac{10}{23}=\frac{g+2}{g+r+6}[/tex]

[tex]\Rightarrow 10g+10r+60=23g+46[/tex]

[tex]\Rightarrow 10r+14=13g\ quad \ldots(ii)[/tex]

Substitute the value of g in equation (ii)[/tex]

[tex]\Rightarrow 10\times \frac{5}{4}g+14=13g[/tex]

[tex]\Rightarrow \frac{25}{2}g+14=13g[/tex]

[tex]\Rightarrow g=28[/tex]

Therefore [tex]r=35[/tex]

Thus there 28 green counter and 35 red counter

Answer:

2 nights

Step-by-step explanation:

We need to find how many nights Francesca will have to spend to knit the rest of the scarf.

First, we have to find how much she has left to knit, and then find how many nights it will take her.

She has already knit 28 centimeters of scarf.

She wants to knit a total of 42 centimeters of scarf.

Therefore, the length of scarf left to knit is:

42 - 28 = 14 centimeters

She can knit 7 centimeters each night.

Therefore, the number of nights more she needs to knit 14 centimeters is:

14 / 7 = 2 nights

She will spend 2 nights to knit a total of 42 centimeters of scarf.

Step-by-step explanation:

(w circle r) (x) is the composite function(w of r(x)), that is, w(r(x))[/tex]

We have that:

[tex]r(x) = 2 - x^{2}[/tex]

[tex]w(x) = x - 2[/tex]

Composite function:

[tex]w(r(x)) = w(2 - x^{2}} = 2 - x^{2} - 2 = -x^{2}[/tex]

[tex]-x^{2}[/tex] is a negative parabola with vertex at the original.

So the range(the values that y assumes), is:

[tex](-\infty, 0)[/tex]

The range of (w circle r) (x) will be (-∞,0). Option A is correct.

A connection between independent variables and the dependent variable is defined by the function.

Functions help to represent graphs and equations. A function is represented by the two variables one is dependent and another one is an independent function.

The relation between them is shown as y if dependent and x is the independent variable;

Given functions;

[tex]\rm r(x) =2- x^2 \\\\ w(x) =x-2[/tex]

The composite function is found as;

[tex]\rm w(r(x))=w(2-x^2 = 2-x^2-2)\\\\ w(r(x))= -x^2[/tex]

-x² is graphed and shows the negative parabola

The range of (w circle r) (x) will be (-∞,0).

Hence, option A is correct.
