Arada [10]

Answer:

60

Step-by-step explanation:

1 gallon is equal to 30 miles, which would mean if she uses 30 gallons of gas it would be equal to 60 since 3 x 20 equals 60

Hanna baked a cake, she used 6 tenths of flour, 3 eggs and4 fifths of sugar. how man ingredients did she used..
lidiya [134]
Since the question wants to know how many ingredients she used, All we have to do is add them.

So as the question says, she used 6/10 flour, 3 eggs, and 4/5 sugar.

Now we have two fractions in this scenario. Let's make them have the same denominator. Either we divide 6/10 by 2 or multiply 4/5 by 2. Let's multiply.

4/5 × 2 = 8/10

Now we have 6/10, 3, and 8/10

Lets add them together.

3 + 6/10 = 3 and 6/10

Now 3 and 6/10 + 8/10 = 4 and 4/10

Simplify even further...

and your answer will be 4 and 2/5

What is the surface area of the given figure?
morpeh [17]

Answer:

D. 2,280 cm²

Step-by-step explanation:

Surface area of triangular prism = bh + (S1 + S2 + S3)*L

Where,

b = 24 cm

h = 10 cm

S1 = 26 cm

S2 = 24 cm

S3 = 10 cm

L = 34 cm

Plug in the values

Surface area = 24*10 + (26 + 24 + 10)*34

= 240 + 2,040

= 2,280 cm²

Triangles PIC Included
ZanzabumX [31]

Answer:

sin70° = x/6

Step-by-step explanation:

When we draw out our picture and triangle, we should see that our angle is on the ground 70°, the height <em>x</em> is across from the angle and is the vertical leg up, and that our hypotenuse is equal to 6:

sin70° = x/6

What is the derivative of the following function? f(x) = 4x^6/cos^5(x)
KIM [24]

Answer:

f'(x) = \frac{24x^{5} \cos x + 20x^{6}\sin x}{\cos^{6}x }

Step-by-step explanation:

We have to find the derivative of the following function:

f(x) = \frac{4x^{6} }{\cos^{5} x }

Now, differentiating both sides with respect to x we get,

f'(x) = \frac{\cos^{5}x (24x^{5}) - 4x^{6}(5\cos^{4}x )(- \sin x)}{(\cos^{5}x )^{2}}

⇒ f'(x) = \frac{ 24x^{5} \cos x + 20 x^{6}\sin x}{\cos^{6}x } (Answer)

{Since, we know that, \frac{d(mx^{n} )}{dx} = m \times n x^{(n - 1)} and \frac{d(\cos^{n} x)}{dx} = n \cos^{(n - 1)} x(- \sin x) }
