Which expression is equivalent to 6-8 x 65?
Answer:
12-16 X 130
Step-by-step explanation:
Lol its asking for an equivalent expression meaning the same thing soooo... I just multiplied each number by two: 6X2= 12) 8X2=16) 65X2= 130) so the expression will be 12-16 X 65.
ps.
If u get any other answers with a different one than mine it doesnt mean its incorrect because there are infinite equivalent answers for this expression
PLZ HELP ASAP WILL MARK U BRANLYEST... thanks:)
Step-by-step explanation:
Here we are going to use the Pythagoras theorem to get the Hight of the Television
[tex] {42}^{2} - {32}^{2} = x[/tex]
X Being the unknown side
[tex] {42}^{2} - {32}^{2} = 740 \\ x = \sqrt{740} = 27.2[/tex]
So the height is 27.2in
The Are of the screen would be L x B
27.2 x 32 = 870.2 in^2
We will use Pythagoras for the last question also
[tex] {40}^{2} + {32}^{2} = 2624 \\ \sqrt{2624} = 51.23[/tex]
She will need 51.23 in screen size

Evaluate the function, find f(-2):
f(x) = 2x^2 +3x
Answer:
B) 2
Step-by-step explanation:
f(-2) = 2 * (-2)^2 + 3(-2)
f(-2) = 2 * 4 - 6
f(-2) = 8 - 6
f(-2) = 2
Americans eat an average of 100 acres of pizza per year. That is equivalent to 4,356,000 square feet of pizza per year. How is the area expressed using scientific notation?
Answer:
D. [tex] 4.356 * 10^6 [/tex] ft²
Step-by-step explanation:
Scientific notation of a number is expressed in the following form, [tex] a * 10^b [/tex]
Where,
a = decimal number (1 ≤ |a| < 10)
b = the power of 10 whereby the scientific notation is equivalent to the original number.
To express 4,356,000 square feet in scientific notation, do the following:
1. Move the decimal point to the left up to the last non-zero digit = a = 4.356
2. Since we moved the decimal point by 6 decimal places, therefore, b = 6
3. Substitute the values of the variables into
Thus:
4,356,000 = 3. Substitute the values of the variables into
a * 10^b
Thus:
4,356,000 = 4.356 * 10^6

You can think of percentages in terms of fractions. Describe how you can think about 10%, 25%, and
75% by using fractions. Consider using tape diagrams to support your explanation
Answer:
You can think percentages as fractions by always using the denominator as 100 and the percentage as the numerator. For example, 10% would be 10/100 or 1/10 and 25% as 25/100 or 1/4 and 75% as 75/100.
