Answer:

StartFraction 5 Over y cubed EndFraction

Step-by-step explanation:

We are given an expression that is 5y^{- 3} and we have to find the equivalent expression for that from the given four options.

Now, we can write the expression as

5y^{- 3}

= \frac{5}{y^{3} } {Since we know the property of exponents as x^{- a} = \frac{1}{x^{a}}}

Therefore, the correct option is C i.e. StartFraction 5 Over y cubed EndFraction. (Answer)

Does the construction demonstrate how to bisect a segment correctly by hand?
nadya68 [22]

Answer:

see below (I hope this helps!)

Step-by-step explanation:

First of all, we can clearly tell that a straightedge was used to create CD but that doesn't prove anything so we can eliminate the second and fourth options. Upon measuring the lengths of AC and CB, we see that they are equal so the answer is Yes; the compass was kept at the same width to create the arcs for points C and D. The reason why this is so important is because we know that AC = CB = BD = DA because the compass width is the same, so therefore, ACBD is a rhombus based on the definition of a rhombus. We know that the diagonals of a rhombus bisect each other and since CD and AB are diagonals, we know that CD bisects AB.

What is the product of 5.86 × 10–7 and 3.1 × 104 1. Write the expression: (5.86 × 10–7)(3.1 × 104) 2. Rearrange the expression:
Reil [10]

Answer:

The value of the exponent of the base 10 for this product is -2.

Step-by-step explanation:

5.86\,\,10^{-7}\,\,*\,\,3.1\,\,10^4=18.166\,\,10^{-7+4}=18.166\,\,10^{-3}

Now, in order to represent this number in scientific notation, we need to reduce the coefficient 18.166 to a coefficient larger or equal to 1 and smaller strictly than 10, by using division or multiplications by powers of 10. In order to reduce it to 1.8166, we need to divide the original 18.166 by ten so we do the following in order not to change the given number (multiply and divide by ten at the same time):

\frac{18.166\,\,10}{10} \,10^{-3}=1.8166\,*\,10\,*\,10^{-3}=1.8166\,\,10^{-2}

Solve problems about a lemonade stand, and write about the solutions. Cups $2 Lemons $8 Sugar $3 Juan wants to start a lemonade
Fofino [41]

Answer:

$3 from his pockets

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

To begin solving this problem we need to first calculate how much money all the supplies will cost. We do this buy adding up the prices of each individual supply. Like so,

2+8+3 = 13

Now we can see that the total amount of the supplies is $13. Since his mom loaned him $10 we can subtract that from the total cost.

13-10 = 3

Finally, we can see that Juan would need to pay a total of $3 from his pockets to be able to buy all the ingredients.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Worth 80 points!! It's alot for me to understand and i wanna get it right someone help?
Mandarinka [93]

Add all the new budget amounts:

510 + 254 + 295 + 51 + 0 + 100 + 100+ 0 + 100 = 1410


Her monthly total is 1410, which is less than her income of 1700

1700 - 1410 = 290

She has $290 extra each month.

So she can divide that amount by 2 to put an equal amount in each blank category, or add what ever amount less than that into each one.

Alex Ar [27]

Answer:

They will reach the Bar Harbor in 8 days.

Step-by-step explanation:

The distance between the San Diego, California, to Bar Harbor, Maine is 3302 miles.

Now, the Garcia family is driving from San Diego, California, to Bar Harbor, Maine. The distance that they have traveled is 2,045 miles in 5 days.

So, in this rate they will reach the Bar Harbor, in \frac{3302}{2045} \times 5 = 8 days (Approximate) (Answer)

Since the rate of movement is constant, so we can use the unitary method to find the total time to reach destination.
