10 inches squared because the scale is shown in the legenth the smaller one is 2 and the bigger one is 10 so the smaller one if 5 times smaller so you multiply the area by 5

Well, if GHJK is just a smaller version of LMNP, then they are proportional to each other.

It's saying that the small rectangle is 2 square inches. You can tell then that it is a 2in x 1in rectangle. You know that the ratio of between the long sides is 2:10. If we say that the shorter sides of the larger rectangle is x. Then we should know that the 2:10 proportionality will be true for 1:x. Well, 2 is to 10 as 1 is to 5. So the big rectangle has side lengths of 10 in and 5 inches. I'll let you go from there.

A dairy wishes to mix together 1,000 pints of milk that contains 8% butterfat. if the mixture is to be made from milk containing

cricket20 [7]

We can write the question as a mathematical formula as follows:
1000 * 0.08 = m * 0.05 + c * 0.2
1000 = m + c
where m are pints of milk and c are pints of cream
So solving the first equation with m = 1000 - c
1000*0.08 = (1000-c)*0.05 + c*0.2
80 = 50 - 0.05c + 0.2c
80-50 = (0.2-0.05)*c
30 = 0.15*c
c = 30/0.15
c = 200
m = 1000-200 = 800
So the dairy needs 800 pints of milk and 200 pints of cream

Answer:

$64^{\circ}$

Step-by-step explanation:

$~~~~~~\cos \angle E = \sin \angle F\\\\\implies \cos 26^{\circ} = \sin \angle F\\ \\\implies \angle F = \sin^{-1} \left( \cos 26^{\circ} \right)\\\\\implies \angle F = \sin^{-1} \left(\sin(90^{\circ}-26^{\circ}) \right)\\\\\implies \angle F = \sin^{-1} \left( \sin 64^{\circ} \right)\\\\\implies \angle F = 64^{\circ}$

The reciprocal of (x-y) is z . If z = 11 , y = -3 then what is the value of x

arlik [135]

Answer:

x=-32/11

Step-by-step explanation:

Let's solve your equation step-by-step.

1/(x+3)=11

(1/n=reciprocal of n)

Step 1: Multiply both sides by x+3.

1=11x+33

11x+33=1(Flip the equation)

11x+33−33=1−33(Subtract 33 from both sides)

11x=−32

11x/11=−32/11

(Divide both sides by 11)

x=−32/11

Check answers. (Plug them in to make sure they work.)

x=−32/11

(Works in original equation)
