If an hour is 45 years how long is a minute

Mathematics
1 answer:
Ainat [17]3 years ago
8 0
Since one hour = 45 years, one minute should be 1/60th of 45 years because 60 minutes = an hour.

45/60 = 3/4

So one minute would be 3/4 of an hour, or 45 minutes.

Hope this helps!

Consider a circle with radius 5 and another circle with radius 3. Let d represent the distance between the two centers.We want t
ElenaW [278]

Answer:

If d<2, there is no intersection

If d=2, there is one intersection

If 2<d<8, there are two intersections

If d=8, there is one intersection

if d>8, there is no intersection

Step-by-step explanation:

If d<2 (the difference between both radius is 2), the little circle is inside the big one. Thus there is no intersection.

If d=2, the little circle is inside but tangent to the big one. There is one intersection then.

If 2<d<8, there are two intersections since the little circle has a portion outside the big one, and another portion inside.

If d=8, the little circle is tangent to the big one from outside. There is one intersection then.

if d>8, the little circle is completely exterior to the big one. Thus, there is no intersection.

Please find attached the figure for d = 10. The big circle is centered and the other is offset by 10.

Which conic section does the equation below describe?
Rus_ich [418]

Answer: Option C. Ellipse

Step-by-step explanation:

The general equation of an ellipse has the following form:

\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2} =1

Where the point (h, k) is the center of the ellipse

In this case we have the equation

\frac{(x-9)^2}{4} + \frac{(y+2)^2}{25} =1

Note that its shape matches that of a ellipse with center (9, -2)

a=\sqrt{4} \\a=2\\\\\\b=\sqrt{25}\\b=5

Therefore the answer is the obtion C

The new pastry chef at Jackson's Bakery specializes in sheet cakes for parties. She sold 17 small, 11 medium, and 20 large sheet
Nataliya [291]

Answer:

Therefore the total amount that Jackson's Bakery made in one week from sheet cakes is: = $2,238

Step-by-step explanation:

Step One:

To arrive at the total amount made from the sheet cakes, we have to assign the prices of each type of cake. They are:

  1. Small Sheet Cake - $36
  2. Medium Sheet Cake - $46
  3. Large Sheet Cake - $56

Step Two:

If the new pastry sold 17 small, 11 medium and 20 large sheet cakes respectively, the total money made comes to the following:

= (36 x 17) + (11 x 46) + (56 x 20)

= 612 +  506 + 1120

Therefore the total amount that Jackson's Bakery made in one week from sheet cakes is:

= $2,238

Cheers!

Solve the equation 2x2 + 13x + 15 = 0 by factoring. Show all steps.
natita [175]

Answer:

(2x + 3)(x + 5)

Step-by-step explanation:

2x² + 3x + 15 = 0

(2x + 3)(x + 5)

2x + 3 = 0

2x = -3

x = -3/2

x + 5 = 0

x = -5
