What square roots of 10 lies between which two whole numbers?

Answer:

60

Step-by-step explanation:

y+y+60=180

2y =120

therefore,y=60

Answer:

C. 60°

Step-by-step explanation:

To answer this problem we must make use of the sum of the internal angles of a triangle.

For any triangle the sum of its internal angles is equal to 180 °.

So we must add all the angles to find the answer:

[tex]y+y+60=180[/tex]

now we can add the two terms 'y'

[tex]2y+60=180[/tex]

and now we clear for 'y':

[tex]2y=180-60\\2y=120\\y=120/2\\y=60[/tex]

The value of y is 60°

Answer:

The dolphin speed in miles per hour is 6

Step-by-step explanation:

we know that

1 mi=1,609.34 m ------> 1 m=1/ 1,609.34 mi

1 h= 3,600 sec ----> 1 sec=1/3,600 h

we have

[tex]2.68\frac{m}{sec}[/tex]

Convert to mi/h

[tex]2.68\frac{m}{sec}=2.68\frac{(1/1,609.34)}{(1/3,600)}=6\frac{mi}{h}[/tex]

Answer:

x = y + 8

Step-by-step explanation:

Given

y = x - 8 ( add 8 to both sides )

y + 8 = x

Final answer:

To make x the subject of the equation y = x - 8, simply add 8 to both sides of the equation to get x = y + 8, which is the rearranged equation.

Explanation:

To rearrange the equation y = x - 8 to make x the subject, you need to isolate x on one side of the equation. Here are the steps to do so:

Add 8 to both sides of the equation to get y + 8 = x.

Once you have done that, the equation is already solved for x, and the new equation with x as the subject is x = y + 8.

This process is common in algebra when solving linear equations or finding the equation of a line, similar to when you want to determine the line of best fit in a set of data points. For example, in the equation y = 9 + 3x, rearranging to solve for x would involve subtracting 9 from both sides and then dividing by 3.

Answer:  Range: y = {-7.5, -5, 10, 15}

Step-by-step explanation:

Domain is "x" and range is "y" f(x)

Replace the x's in the equation with each given value:

[tex]f(x)=3x-\dfrac{x}{2}\qquad \qquad \text{when}\ x={-3, -2, 4, 6}\\\\\\\\f(-3)=3(-3)-\bigg(\dfrac{-3}{2}\bigg)\\\\\\.\qquad =-9+\dfrac{3}{2}\\\\\\.\quad =\dfrac{-18}{2}+\dfrac{3}{2}\\\\\\.\quad =\large\boxed{-\dfrac{15}{2}}[/tex]

[tex]f(-2)=3(-2)-\bigg(\dfrac{-2}{2}\bigg)\\\\\\.\qquad =-6+1\\\\\\.\qquad =\large\boxed{-5}[/tex]

[tex]f(4)=3(4)-\bigg(\dfrac{4}{2}\bigg)\\\\\\.\qquad =12-2\\\\\\.\qquad =\large\boxed{10}[/tex]

[tex]f(6)=3(6)-\bigg(\dfrac{6}{2}\bigg)\\\\\\.\qquad =18-3\\\\\\.\qquad =\large\boxed{15}[/tex]

The range of the function with the specified domain of {-3, -2, 4, 6} is {-15/2, -5, 10, 15}.

The student asks: if fx=3x-x/2 find the range if the domain is {-3,-2,4,6}. To find the range of the function f(x) = 3x - x/2, we will evaluate the function for each value in the given domain and record the corresponding outputs. This function simplifies to f(x) = (5/2)x when you combine like terms.

For x = -3, f(-3) = (5/2)(-3) = -15/2.

For x = -2, f(-2) = (5/2)(-2) = -10/2 = -5.

For x = 4, f(4) = (5/2)(4) = 20/2 = 10.

For x = 6, f(6) = (5/2)(6) = 30/2 = 15.

Just divide one by another and you'll get the ratio

4000/15 = 800/3 ≈ 266,67

So 4000 is 266,67 times greater than 15

Answer:

266.666 or 266.67

Step-by-step explanation:

You´d divide 4000 by 15 and you get 266.666, which can be simplified to 266.67.

Answer:

x different from 2

Step-by-step explanation:

The function is written as the quotient: [tex]\frac{x+3}{x-2}[/tex]

that can give us a real value for any value of x except for x=2 that creates a ZERO in the denominator, making the division undefined.

So the only value for which the function cannot be evaluated is x=2, therefore the function's domain is all the real numbers except for x=2.

For this case we have that the total minutes spent in yoga classes last week was 165.

Subtracting the 45 minutes of the Saturday day we have:

[tex]165-45 = 120[/tex]

Those 120 minutes were distributed in the weekly yoga classes

where each lasted 30 minutes.

[tex]\frac {120} {30} = 4[/tex]

It is composite

Step-by-step explanation:

Using the given number line, the plotted number is 1000 when rounded to the nearest thousand.

How to round a number to the nearest thousand?

To round a number to the nearest thousand, you need to identify the digit in the thousands place and then decide whether to round up or down based on the digit in the hundreds place.

Now, the nearest number too the plotted dot is 1000.

Thus, we can clearly conclude that the using the given number line, the plotted number is 1000 when rounded to the nearest thousand.

Answer:

7.2 Hours

Step-by-step explanation:

To find the mean which is also known as the average of a set of data, you first have to add all the numbers then divide the sum by the amount of data values. (I remember this by saying the mean teacher averages your grade.)

First, you need to add the numbers. 5+5+5+4+17= 36

Secondly, you need to divide the sum of all the data by the amount of data there is. In this case, there are 5 pieces of data.

Lastly, you divide 36/5

Your final answer should be 7.2

You can check your work by doing 7.2 times 5 which equals 36.

Answer:r

Step-by-step explanation:

let x and y this numbers : x +y = -103 and x = y +59

so : y+59 +y = -103

2y +59 = -103

2y +59-59 = -103-59

2y = -162

y = -162/2

y = -81  but  x = y +59

so : x = -81+59

x = -22

The two numbers satisfying the given condition is -22 and -81.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have sum of two numbers is -103. One number is 59 less than the other.

Assume that the first number is [x]. Then, another number would be (x - 59).

We can write -

x + (x - 59) = - 103

2x - 59 = - 103

2x = - 103 + 59

2x = - 444

x = - 22

Another number would be -

x - 59 = - 22 - 59 = - 81

Therefore, the two numbers satisfying the given condition is -22 and -81.

Answer: 600.62

Step-by-step explanation:

1018 x 0.59 = 600.62

Answer:

600.6. to the nearest tenth.

Step-by-step explanation:

59 % = 59/100 = 0.59.

0.59 * 1018

= 600.6.

Step-by-step explanation:

given

[tex](1.5 \times {10}^{4} )(8 \times {10}^{8} )[/tex]

in order to make multiplication easier we need to change the 1.5 into a whole number form.

thus

[tex](15 \times {10}^{ - 1} \times {10}^{4} )(8 \times {10}^{8} )[/tex]

[tex] = (15 \times {10}^{4 - 1} )(8 \times {10}^{8} )[/tex]

First law of indices applied there

=(15×10^3)(8×10^8)

=(15×8)(10^3×10^8)

=120×10^3+8 ( first law of indices, which states that , numbers of the same base multiplying each other, take one of the base and add the exponent. and clearly both 15 and 8 are in base 10

=120×10^11

=1.20×10^2 ×10^11

=1.20×10^11+2

=1.20×10^13

so the answer is alt B

(1.5 x 10^4)(8 x 10^8) written in scientific notation will be  1.2×10¹³.

We write standard numbers in scientific form as it can be written in more compact way.Think of writing a billion in copy and writing it in scientific notation.

Given (1.5×10⁴)(8×10⁸) and we have to write it in scientific form.

Let us first multiply the bases which are (8×1.5) = 12 and 10⁴×10⁸ is 10⁴⁺⁸ = 10¹².

∴ (1.5×10⁴)(8×10⁸) = 12×10¹² but is scientific natation base should be less than 10 so we'll a decimal one digit before 12 like dividing it by 10 so to balance it out we also have to multiply by 10 we'll multiply that 10 to the 10¹² which will make it 10¹³.

∴ 12×10¹² = 1.2×10¹³.

Final answer:

To find the tax on a $76 automobile tune-up at 8.25%, convert the tax rate to a decimal (0.0825), multiply it by the tune-up cost ($76), resulting in a tax of $6.27. Adding the tax to the original cost gives a total price of $82.27.

Explanation:

To calculate the amount of tax on an automobile tune-up costing $76 with a tax rate of 8.25%, first, you need to convert the percentage to a decimal. The decimal form of 8.25% is 0.0825. Then multiply the cost of the tune-up by this decimal:

The amount of tax to be paid is $6.27. To find the total price of the tune-up with tax, you simply add the tax amount to the original tune-up cost:

Therefore, the total price of the automobile tune-up including tax is $82.27.

The value of the number whose two thirds part is equal to the number 36 is number 54.

A fraction number is the number which is a part of a whole number. It is written with a numerator and denominator. Fraction number are written as,

[tex]\dfrac{a}{b}[/tex]

Here (a) is the numerator and (b) is the denominator.

Two thirds of a number is 36. Let suppose the number is x. As it is given that the two third of this number x is equal to the 36.

Thus, we have to multiply the fraction 2/3 to x and equate it to 36.

[tex]x\times\dfrac{2}{3}=36\\x=\dfrac{36\times3}{2}\\x=54[/tex]
