Answer:

5/3

Step-by-step explanation:

If you do 5/ 3/5 what youre really doing is just doing two division problems which by the way equals 5/0.6 or 8.3333333

But one thing i realized when i was doing division by fractions is that if you flip the fraction then you can multiply and you get the same exact answer. SO lets try: 5/3 = 1.6666

1.6666*5=8.3333333

So you can use that trick when dividing a whole number by fractions. It makes it a lot easier.

The official answer is instead of dividing 5 by 3/5 you can instead multiply 5 by 5/3 and get the same answer!

Answer:

t = [tex]\frac{6}{7}[/tex]

Step-by-step explanation:

Given that t varies inversely as the square root of u then the equation relating them is

t = [tex]\frac{k}{\sqrt{u} }[/tex] ← k is the constant of variation

To find k use the condition t = 3 when u = 4, thus

k = t[tex]\sqrt{u}[/tex] = 3 × [tex]\sqrt{4}[/tex] = 3 × 2 = 6

t = [tex]\frac{6}{\sqrt{u} }[/tex] ← equation of variation

When u = 49, then

t = [tex]\frac{6}{\sqrt{49} }[/tex] = [tex]\frac{6}{7}[/tex]

The value of 't' when 'u = 49' in the equation [tex]'t = k/\sqrt(u)[/tex]' is approximately '0.86'. This was calculated using the concept of inverse variation in mathematics.

The question is dealing with the concept of inverse variations in math. The given expression states that 't' varies inversely with the square root of 'u'. This can be represented mathematically as  [tex]'t = k/\sqrt(u)',[/tex] where 'k' is the constant of variation.

From the problem we know that 't = 3' when 'u = 4'. Substituting these terms in into the equation above, we can solve for 'k'. Doing this yields  [tex]'k = 3\times \sqrt(4) = 6.'[/tex]

Now that we have found 'k', we can find the value of 't' when 'u = 49'. We can do this by plugging in the known values into the equation. So [tex]'t = 6/\sqrt(49)'.[/tex] It simplifies to 't = 6/7' or about '0.86'.

Answer:

It is A

Explanation:

Two points will always be collinear, but the same can't be said for three, since in some occasions one point is outside the line.

When multiple of the same number are multiplied together, this can be represented as an exponent. An exponent is a way to write repeated multiplication of a number by itself. In your case, 7 multiplied by itself 3 times (7*7*7) can be written using exponents as 7^3.

In mathematics, when you multiply the same number multiple times, you can express that multiplication as an exponent. An exponent tells you how many times to multiply the number, or the base, by itself. For example, in your question, the number 7 is multiplied by itself 3 times (7*7*7), so this multiplication can also be written with exponents. The correct way to express this multiplication using exponents is 73.

The answer is D, 26. [tex]3\pi^2[/tex] is about 26.6!

Final answer:

The number that is between 21 and 3π/2 is 5.

Explanation:

To find the number that is between 21 and 3π/2, we need to determine the value of 3π/2 first. Since π is approximately 3.14, 3π/2 is approximately (3)(3.14)/2 = 4.71.

Now we can compare this value to 21. Since 4.71 is less than 21, we need to find a number that is greater than 4.71 but less than 21. The only option in the given choices that fits this criteria is Option C, 5.

Answer:

6 x 6 x 6

Step-by-step explanation:

Six to the third power means to multiply 6 by itself 3 times.

The standard exponential function is expressed as y = ab^x. The value for the simplified form of 6 to the third power is 216

The standard exponential function is expressed as y = ab^x

Given the following parameters

Answer:

72.5 miles/hour

Step-by-step explanation:

When we say "miles per hour" in English this just is simply the question "If Bailey drove for only one hour, how far did she go?". Now mathematically we can find this very easily by simply dividing 290 by 4, which is equal to 72.5. So Bailey travels 72.5 miles every hour.  

If it is confusing about why we do this, think about splitting up 290 miles evenly between 4 hours, how many miles does each hour 'get'. Each would 'get' 72.5 miles. So for every hour Bailey drives she travels 72.5 miles which is the same as saying that she drove at 72.5 miles per hour.

There are 3 dots in each row of Fritz's array. This conclusion is reached by dividing the total number of dots (15) by the number of rows (5). This is an exercise in simple division and understanding arrays in mathematics.

The subject of this question from Fritz is Mathematics, specifically, it's about arrays and simple division.

To find out how many dots are in each row of Fritz's array, we need to use division. In this case, the total number of dots (15) would be divided by the number of rows (5).

So, we calculate: 15 ÷ 5 = 3.

So, there are 3 dots in each row of Fritz's array. We know this is correct because the definition of an array in mathematics is a collection of objects or numbers arranged in rows, and each row has the same number of items.

Answer:

Step-by-step explanation:

We have been given a function [tex]f(x)=x+3[/tex]. We are asked to find the inverse of the given function.

First of all, we will replace [tex]f(x)[/tex] by y as:

[tex]y=x+3[/tex]

Now, we will interchange x and y variables as:

[tex]x=y+3[/tex]

Solve for y:

[tex]x-3=y+3-3[/tex]

[tex]x-3=y[/tex]

Switch sides:

[tex]y=x-3[/tex]

Therefore, the inverse function for the given function would be [tex]h(x)=x-3[/tex].

Mixture 1 and Mixture 2 will create the same color

Step-by-step explanation:

we know that

If two mixtures create the same color, then the proportion of the painting in the mixtures must be the same

Let

x ----> the ounces of a red paint in the mixture

y ----> the ounces of a blue paint in the mixture

Verify the proportion of the paints in each mixture

Mixture 1) x=2, y=1

[tex]\frac{2}{1}=2[/tex]

Mixture 2) x=7, y=3.5

[tex]\frac{7}{3.5}=2[/tex]

Mixture 3) x=4.5, y=2

[tex]\frac{4.5}{2}=2.25[/tex]

Mixture 4) x=5.5, y=2.5

[tex]\frac{5.5}{2.5}=2.2[/tex]

therefore

Mixture 1 and Mixture 2 will create the same color, because have the same ratio

Answer:

Mixture 1 and Mixture 2

Step-by-step explanation:

It is given that Raj is mixing different colors (blue and red) of paint to make a new color.

If two mixtures have same ratio of red and blue color, then that will create the same color.

The ratio of red and blue color in each mixture is shown below:

Mixture 1: [tex]\frac{Red}{Blue}=\frac{2}{1}=2:1[/tex]

Mixture 2: [tex]\frac{Red}{Blue}=\frac{7}{3.5}=\frac{2}{1}=2:1[/tex]

Mixture 3: [tex]\frac{Red}{Blue}=\frac{4.5}{2}=\frac{9}{4}=9:4[/tex]

Mixture 4: [tex]\frac{Red}{Blue}=\frac{5.5}{2.5}=\frac{11}{5}=11:5[/tex]

From the above calculation it is clear that the ratio of red and blue color in mixture 1 and mixture 2 is same.

Therefore, Mixture 1 and Mixture 2 will create the same color.

Answer:

The estimate of the product is about 35 answer C

Step-by-step explanation:

- We use rounding to estimate the product of two fractions

- The mixed number has whole number and fraction

- To round the mixed number we look to the fraction

- If the numerator is half or greater than half the denominator, then we

  add the whole number by 1 and cancel the fraction

- If the numerator is less than half the denominator, then we keep the

  whole number as it and cancel the fraction

- Ex: If the mixed number is [tex]2\frac{3}{4}[/tex], 3 is more than

 half 4 then we will add 2 by 1 and cancel the fraction part, the

 mixed number [tex]2\frac{3}{4}[/tex] after rounding is 3

- Ex: If the mixed number is [tex]5\frac{1}{4}[/tex], 1 is less than

 half 4 then we will keep 5 as it and cancel the fraction part, the

 mixed number [tex]5\frac{1}{4}[/tex] after rounding is 5

* Lets solve the problem

∵ In the part [tex]4\frac{3}{4}[/tex] 3 is more than half 4

∴ The rounding value of [tex]4\frac{3}{4}[/tex] is 5

∵ In the part [tex]7\frac{2}{17}[/tex] 2 is less than half 17

∴ The rounding value of [tex]7\frac{2}{17}[/tex] is 7

∴ [tex]4\frac{3}{4}*7\frac{2}{17}=5*7=35[/tex]

* The estimate of the product is about 35
