Answer:

grade=15%

Step-by-step explanation:

For 2 ft on x-axis it has elevated 0.3 ft on y-axis

m=0.3/2=0.15 ft

grade=m x 100

The answer required in ratio is: b:c = 9:8

Step-by-step explanation:

We are given:

The ratio a:b = 2:3 and the ratio a:c = 3:4

We need to find the ratio b:c

a:b=2:3 can be written as:

[tex]\frac{a}{b}=\frac{2}{3}[/tex]

Finding value of a by cross multiplying:

[tex]\frac{a}{b}=\frac{2}{3}\\3a=2b\\a=\frac{2b}{3}[/tex]

a:c = 3:4 can be written as: [tex]\frac{a}{c}=\frac{3}{4}[/tex]

Putting value of a and finding b:c

[tex]\frac{a}{c}=\frac{3}{4}\\Put\:a=\frac{2b}{3}\\\frac{2b}{3}}\times \frac{1}{c}=\frac{3}{4} \\Finding\:value\:of\:b/c\\\frac{b}{c}=\frac{3\times 3}{4 \times 2}\\ \frac{b}{c}=\frac{9}{8}[/tex]

So, we get the value of [tex]\frac{b}{c}=\frac{9}{8}[/tex]

The answer required is in ratio so: b:c = 9:8

Answer:

Ellipse

Step-by-step explanation:

From the given information:

Suppose the plane cuts the cone in such a manner that the plane is neither perpendicular nor parallel to the axis and also the angle of intersection is greater than the generator angle.

Then the conic section formed is an Ellipse.

The Conic Section that is formed from the intersection of the central axis at an angle between 40° and 90° will be An Ellipse.

Let us consider that the plane cuts the cone in such a manner that the plane is neither perpendicular nor parallel to the axis and also the angle of intersection is greater than the generator angle.

Thus, we can say that when the plane intersects the double-napped cone in such a manner that the angle between the vertex and the angle is greater than the vertex angle.

Then the resulting conic section formed is an Ellipse.

Test statistic (t) = 0.625

Step-by-step explanation:

Step(i):-

mean of the Population(μ) = 10.4 hours

Sample mean (x⁻) = 10.7 hours

Standard deviation of the sample( S)  = 1.44

The level of significance (α= 0.1

Sample size 'n' = 9

Degrees of freedom = n-1 = 9-1 =8

Step(ii):-

Test statistic

                     [tex]t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }[/tex]

                   [tex]t = \frac{10.7 -10.4}{\frac{1.44}{\sqrt{9} } } =0.625[/tex]

Step-by-step explanation:

Each cake requires cups of milk = [tex]1\frac{1}{2}[/tex] cups ≈ 1.5 cups

6 cakes will require milk = 6 × 1.5

                                         = 9 cups

Anne has milk = 5 pints

∵ 1 pint = 2 cups

∴ 5 pints = 10 cups

Therefore, Anne has milk = 10 cups

Extra amount of milk Anne has = 10 - 9 = 1 cup

Hence, Answer is yes, she has enough milk. She will have 1 extra cup of milk.

Option 1 will be the answer.

Answer:

45 miles and 110 feet

Step-by-step explanation:

1. Convert into feet (1 miles = 5280 feet)

2431 x 5280 = 12835680

2. Add

12835680 + 660 = 12836340

3. Divide

12836340 divided by 54 = 237710

4. Divide

237710  divided by 5280 = 45 r 110

Answer:

Average = 7.83

Variance = 20.8339

Step-by-step explanation:

Since the average number of teeth lost in years 5-9 was 7 teeth this means that the average was 7 each year. Therefore, to estimate the average of teeth lost per year including all the years then we need to add the average each year and divide by the number of years being included like so...

7 + 7 + 7 + 7  + 7 + 12 =  47 teeth

47 teeth / 6 days = 7.83

Now that we have the mean we can find the variance.

[tex](7-7.83)^{2}[/tex] = 0.6889

[tex](12 - 7.83)^{2}[/tex] = 17.3889

0.6889 + 0.6889 + 0.6889 + 0.6889 + 0.6889 + 17.3889 = 20.8339

(Btw forgive me for my horrible handwriting D: )

Reasoning:

#4 is a segment which is why it's written like that in the image.

#5 is an angle which is why there is the angle symbol before the PQR

#6 is a line which is why there is a line on top of BY

#7 is an angle which is why there is an angle symbol before LMN

Step-by-step explanation:

Answer:

x=3+i or x=3-i

Step-by-step explanation:

x²-6x+10=0

(x²-6x+9) + 1 = 0

(x-3)² + 1 = 0

(x-3)² = -1

x-3 = ± √-1 = ± i

x = 3 + i    or x = 3 - i

The next step is that L in can write her solution using i be like x = 3 + i or x = 3 - i.

Mathematical phrases with two algebraic symbols on either end of the equal (=) sign are called equations. To illustrate this connection, the expressions just on the left and right are demonstrated to be equivalent to each other. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

From the given values provided in the question,

x² - 6x + 10 = 0

(x² - 6x + 9) + 1 = 0

(x - 3)² + 1 = 0

(x - 3)² = -1

x - 3 = ±√-1

x - 3 = ± i

x = 3 + i or,    

x = 3 - i

Answer:

the tree would be 45 feet tall

Step-by-step explanation:

so the house is 30 feet and 50 feet shadow, if you divide by 2 you can see that every 15 feet gives a 25 foot shadow, since 75-50 is 25 so in turn if the tree is 45 feet tall, it will make 75 foot shadow

Answer:

c. y = x - 6

Step-by-step explanation:

This question wants you to find the equation in slope-intercept form, each is y=mx+b, where m is the slope and b is the y-intercept. The first thing to do is find the y-intercept, to do this find the value of y when x equals zero. The way to do this is to look the value of y on the y-axis. In this case, the y-intercept is -6. Then, find the slope; since you are given the graph you can count out the slope. To do this find out how much the y and x values change. On this graph, y increases 1 when x increases 1, so the slope is 1/1 or one 1. So the equation is y=1x-6, which simplifies to y=x-6.
