Answer:

B. 6.

Step-by-step explanation:

When x = 3 the prediction is 2.5(3) - 1.5

= 6.

The value of y at x = 3 is,

⇒ y = 6.0

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

A data set consists of the following data points:

⇒ (2, 4),(4, 7), (5, 12)

And, The line of best fit has the equation;

⇒ y = 2.5x - 1.5.

Now, At x = 3;

⇒ y = 2.5x - 1.5.

⇒ y = 2.5 × 3 - 1.5.

⇒ y = 7.5 - 1.5

⇒ y = 6.0

Thus, The value of y at x = 3 is,

⇒ y = 6.0

Answer:

95 ft 10 in

Step-by-step explanation:

We need to add the lengths of the front of the house and both sides of the house:

50 ft 8 in + 2(22ft + 9in)

= 50ft + 8 in + 44ft + 18in

= 94ft + 22in

12 inches = 1 foot

22 inches = 1 ft 10 in

Therefore, the length of the gutter he must buy must be:

94 ft + 1 ft + 10 in

= 95 ft 10 in

Answer:

[tex]l = \frac{S}{\pi r} - r[/tex]

Step-by-step explanation:

Given the surface area of a cone expressed as S = [tex]\pi r^{2} +\pi rl[/tex] where r is the radius of the cone and 'l' is its slant height. To find the slant height from the formula, we will make l the subject of the formula as shown;

[tex]S = \pi r^{2} + \pi rl\\S = \pi r (r + l)\\\frac{S}{\pi r} = r+l\\l = \frac{S}{\pi r} - r\\[/tex]

The final expression gives the value of the slant height.

Answer:

$839.95

Step-by-step explanation:

The dining set costs 785.

The sale tax is 7%

This means that the tax costs 7% of 785.

Sales tax: 785*0.07=54.95

Add to original price to find the total price.

54.95+785=839.95

The cost to purchase the dining set is $839.95

x=11 or x=-3 (rejected cos negative)

Answer:

98 °

Step-by-step explanation:

We know that the sum of the angles in a triangle is 180. We also know that angle DAB is 122°, meaning that angle CAB is 180-122, which is 58°. We also know that angle CBA is 24 degrees. Therefore, angle x is just 180-(58+24), which is 98

Answer:

V=πr2h

3

Step-by-step explanation:

Answer:

15 cm³

Step-by-step explanation:

The formula for the volume of a cone is:

V = πr²h /3

where r is the radius and h is the height

Let's substitute the given values into this equation:

V = πr²h /3

(Remember that the base of a cone is a circle and the formula for the area of a circle is πr²)

V = πr²h /3

V = (5)(9/3)

Solve:

V = (5)(9/3)

V = (5)(3)

V = 15

Therefore, the volume of the cone is 15 cubic centimeters.

Convert the mixed numbers to improper fractions, then find the LCD and combine.

Answer:

The watch is cheaper in Geneva, Switzerland by a value of £20

Step-by-step explanation:

To get the city in which the watch is cheaper, what we need to do is to express the price of the watch in the same currency.

Since pounds is also used in the b part of the question, it would be easier working with it.

In Geneva, the price of the watch is 193.75 CHF

from our conversion formula;

£1 = 1.55 CHF

£x = 193.75 CHF

We cross multiply to get the value of x

(193.75 * 1)/1.55

= 193.75/1.55 = £125

We can see that the watch costs less in Geneva and higher in Manchester

By how much is it cheaper?

We can calculate this by subtracting the value in Geneva from the value in Manchester

That would be 145-125 = £20 cheaper

Answer:

Exact form:

130/21

Decimal form:

6.190476 (repeating decimal)

Mixed number form:

6 4/21

Let's start with sectioning off the little squares on the left that are jutting out of the top and bottom. Both of the squares are C*E, so multiply C*E twice to get the area of those little squares. That comes out to 12 feet.

Next is the main quadrilateral, the big one. You have to cut it off at the point the triangle starts to slope, so the end fo B.

But you also have to get the left part, so you have to add the length of C to the length of B to get the length of the quadrilateral. A encompasses the entire height, but not the part we want, because we already isolated those little squares. To get the height, just subtract the two E parts. The height is 6. The length is 8 feet. Multiply and get 48.

Add that to the previous 12 feet calculated to get 60.

Next, the triangle. The height is A, but only with one E. So subract the other E to get a height of 9. The length is D, but you have to subract B because that is part of the earlier quadrilateral. That makes it 9.

The formula for a triangle is height * length / 2. So, plug in the numbers-- 9 * 9 / 2

81/2

40.5.

Add to the previous 60 we got and that makes 100.5 square feet.
