You read a book for 40 minutes. Then you played 3 games on the computer. Each game took 10 minutes to play. Which steps can you use to find the total number of minutes you spent reading your book and playing games?
To find the total number of minutes spent reading and playing games, add the time spent reading and the time spent playing games.
Explanation:To find the total number of minutes spent reading the book and playing games, we can add the time spent reading and the time spent playing games. First, we spent 40 minutes reading the book. Then, we played 3 games, and each game took 10 minutes to play. So, the total time spent playing games is 3 games × 10 minutes/game = 30 minutes. Finally, we can add the time spent reading and the time spent playing games: 40 minutes + 30 minutes = 70 minutes.

To find the total number of minutes spent reading the book and playing games, you can multiply the duration of reading by 1, multiply the number of games played by the duration of each game, and then add the products together. In this case, the total number of minutes would be 70.
Explanation:To find the total number of minutes spent reading the book and playing games, you can follow these steps:
Multiply the number of minutes spent reading (40) by 1.Multiply the number of games played (3) by the duration of each game (10 minutes).Add the products from step 1 and step 2 together to find the total number of minutes.In this case, the calculation would be: 40 minutes (reading) + (3 games × 10 minutes per game) = 40 + 30 = 70 minutes.

WILL MARK BRAINLIEST!! Complete the statements to find the measurements of ∠a and ∠b .
Answer:
angles b and a both equal 60 degrees
Step-by-step explanation:
a and b are both equal to 60 degrees. A flat angle is 180 and you have the one that’s 120 so that one is 60 and then the last side must be 60 as well because when you add them then subtract it from 180 you get 60
Simplify the expression square root of 6 times the square root of 33 plus 7
Answer:
3√(22) + 7
Step-by-step explanation:
The way this is worded can be interpreted two different ways so just to cover the bases, I'll do both. I'm confident they are asking for way 1 though because it wants you to simplify the expression, not evaluate. Way 2 gives you a solution rather than an exact equation.
Number 1
√(6) x √(33) + 7
= √(6 x 33) + 7
= √(198) + 7
= √(9 x 22) + 7
= 3√(22) + 7
Number 2
√(6) x √(33 + 7)
= √(6) x √(40)
= √(6) x (4√(10))
= 4√(60)
= 8√(15)
The simplified expression for [tex]\sqrt{6} \times \sqrt{33} + 7[/tex] is [tex]3\sqrt{22} + 7[/tex]
To simplify square root of 6 times the square root of 33 plus 7 we need to first write it mathematically. We get:
[tex]\sqrt6 \times \sqrt{33}+7[/tex]
Using BODMAS, we first multiply the roots. This will give us:
[tex]\sqrt{6} \times \sqrt{33} + 7 = \sqrt{6 \times 33} +7[/tex]
Now we need to expand the digits in square by expressing them as a product of their prime factors so that common pairs can be taken out of the root. This can be done as follows:
[tex]\sqrt{6 \times 33} +7 = \sqrt{(3 \times 2)\times (3\times11)} +7[/tex]
We can see that there are two pairs of 3. Thus we extract 3 times 3 as it is a perfect square for 9 and we get:
[tex]3\sqrt{( 2\times 11)} +7 = 3\sqrt{2}+7[/tex]
Thus, the simplified expression for [tex]\sqrt{6} \times \sqrt{33} + 7[/tex] is [tex]3\sqrt{22} + 7[/tex]

The area of the surface of a sphere is described by the formula S=4(3.14)r^2. The earth has a radius of 3960 miles and dry land forms 29.2% of the earth’s surface. What is the area of the dry land on earth?
Answer: [tex]57,512,581.63miles^2[/tex]
Step-by-step explanation:
Substitute the value of the radius of the Earth into the formula given in the problem, where r is the radius, to obtain the surface area of the Earth:
[tex]S=4(3.14)r^2\\S=4(3.14)(3,960miles)^2\\S=196,960,896miles^2[/tex]
The problem says that the dry land forms 29.2% of the Earth’s surface, therefore, multiply the surface area by [tex]\frac{29.2}{100}=0.292[/tex]
Threfore, the area of dry land is the following:
[tex]S_{land}=(0.292)(196,960,896miles^2)=57,512,581.63miles^2[/tex]
Final answer:
To find the area of the dry land on Earth, first, calculate the Earth's total surface area with the formula S=4(3.14)r². Given a radius of 3960 miles, this results in about 197,920,640 square miles for the total surface. Multiplying this by 29.2% (or 0.292) gives approximately 57,780,666.88 square miles of dry land.
Explanation:
The question asks for the area of the dry land on Earth, given Earth's radius and the percentage of its surface that is dry land. To find this, first calculate the total surface area of the Earth using the formula S = 4(3.14)r², where r is the radius of the Earth (3960 miles). The formula accounts for the surface area of a sphere. After calculating the total surface area, we then calculate 29.2% of this area to find the dry land's surface area.
Step-by-Step Calculation:
Calculate the total surface area of the Earth: S = 4(3.14)(3960)²
Find the area of the dry land by multiplying the total surface area by 29.2% (or 0.292).
Using the steps above:
S = 4(3.14)(3960)² = 197,920,640 square miles (approx.) as the total surface area.
Area of dry land = 197,920,640 * 0.292 = 57,780,666.88 square miles (approx.).

according to the graph of F(x), which of the statements below are true? check all that apply
Answer:
B, E and F
Step-by-step explanation:
This graph is a log which has an asymptote. This means the function does not cross it and does not have in its domain certain numbers. The asymptote is at -2. This means the domain is greater than -2.
The range is the y-values. With no restrictions here, the function includes all numbers.
This means B, E, and F are true.
The function f(x) is shown in this graph
Answer:
The correct statement is:
The slope of f(x) is same as the slope of g(x)Step-by-step explanation:
We see that the graph of the function f(x) is a line that passes through (0,2) and (1,-1)Hence, the equation of the function f(x) is calculated by a two-point formula as:
[tex]y-2=\dfrac{-1-2}{1-0}\times (x-0)\\\\y-2=\dfrac{-3}{1}\times x\\\\y-2=-3x\\\\y=-3x+2[/tex]
( On comparing the equation of f(x) with slope intercept form.
i.e. y=mx+c
where m is the slope and c is the y-intercept)
We get slope of f(x)= -3
and y-intercept= 2
The function g(x) is given by:[tex]g(x)=-3x-6[/tex]
Hence, slope of g(x) = -3
and y-intercept= -6
Hence, we get that the slope of f(x) and g(x) is same.

A point located at (3, -2) is translated right 3 units and down 4 units. What are the coordinates of the image? (0, -2) (6, -6) (6, 2) (0, -6)
Answer:

Step-by-step explanation:
Because if you move to the right 3 units you add 3 to the x-axis number or in this case 3, so 3+3=6, and if you move down 4 units its the same as subtracting 4 from the y-axis number or in this case -2 so, -2-4=-6. Which gives you (6,-6).

EXPLANATION
The given sequence is
[tex]-3,-14,-25,-36,...[/tex]
The first term of the sequence is
[tex]a_1=-3[/tex]
The common difference is
[tex]d = - 14 - - 3[/tex]
[tex]d = - 11[/tex]
The recursive formula is
[tex]a_{n}=a_{n-1} - 11 \: \: ,a_1 = - 3[/tex]
Answer:
aₙ = aₙ₋₁ -11
Step-by-step explanation:
We have given the sequence:
-3,-14,-25,-36
We have to find the explicit formula.
The first term in this sequence is:
a₁ = -3
The common difference is:
a₂-a₁= -14-(-3) = -11
a₃-a₂ = -25-(-14) = -11
a₄-a₃ = -36-(-25)= -11
Common difference d = -11
The general formula is :
aₙ = aₙ₋₁ +d
Here d = -11 so,
aₙ = aₙ₋₁ -11 is the explicit formula.

Step-by-step explanation:
Given polynomials are ( -x² + 9 ) and ( -3x² - 11x + 4 )
We have to add them.
( -x² + 9 ) + -3x² - 11x + 4 )
-x² + 9 - 3x² - 11x + 4

( -x² - 3x² ) - 11x + ( 9 + 4 )
-4x² - 11x + 13
Therefore, option B is the answer.
