harry wants to bake a small cake so he uses 1 cup of sugar based on the recipe how many cups of flour should he use
erma4kov [3.2K]

I think that Harry should use 1.5-2 cups of flour for his cake. It depends on the size of the cake so if its pretty small, 1.5 cups should work. If you want to take a risk, use more cups of flour.

This is 60 because if you were to 12 times 1 you would get 12 then multiply by 5 and you get 60. Now to check your answer do 12 divided by 12 which gives you 1 and do 60 divided by 12 gives u 5. Therefore the answer is 60cm hope this helps!

stich3 [128]

Answer:

7.0 m/s

Step-by-step explanation:

We can solve this using the 2 kinematic equations and you can use either:

Vf=Vi+at\\\\vf^{2}=vi^{2}+2ad

So let's use the first one.

Vi = initial velocity

Vf = final velocity

a = acceleration due to gravity (constant 9.8m/s²)

t = time

The marble is dropped so this means that it is in free fall. The initial velocity is always 0m/s.

We are given then the following:

d = 2.5m

t = 0.71s

Vi = 0 m/s

a = 9.8m/s²

So we plug in the values we know and solve:

Vf = Vi + at\\\\Vf = 0 m/s + (9.8m/s^{2})(0.71s)\\Vf = 6.958m/s \cong 7.0m/s

Evaluate the double integral ∬Ry2x2+y2dA, where R is the region that lies between the circles x2+y2=16 and x2+y2=121, by changin
olga2289 [7]

Answer:

See answer and graph below

Step-by-step explanation:

∬Ry2x2+y2dA

=∫Ry.2x.2+y.2dA

=A(2y+4Ryx)+c

=∫Ry.2x.2+y.2dA

Integral of a constant ∫pdx=px

=(2x+2.2Ryx)A

=A(2y+4Ryx)

=A(2y+4Ryx)+c

The graph of y=A(2y+4Ryx)+c assuming A=1 and c=2
