converting 0.000098 into scientific notation what is the missing power of 10
Answer:
9.8E^-5 (or 9.8*10^-5)
Step-by-step explanation:
0.000098 converted to scientific notation is either 9.8E^-5 or 9.8*10^-5 as they are the same, just different ways of writing it. To get this, you just count the spaces away from the decimal point the number is.
ex.) 0.98 = 9.8E^-1 as it just has to move 1 decimal
980 = 9.8E^1 as it has to move 1 decimal to the positive side
and so on.

Using Company A's calling plan, the cost of an overseas phone call is a $0.95 connection fee plus 18 cents per minute. If the total cost of the call is $2.75, how long is the phone call?
The total duration of the phone call was 10 minutes.
Given that, by using Company A's calling plan, the cost of an overseas phone call is a $0.95 connection fee plus 18 cents per minute. If the total cost of the call is $2.75 and we have to calculate the time how long was the phone call.
Let the number of minutes a phone call held be x.
Now, we will be representing the above given information in terms of linear equation and then solve for the value of x which will give us the number of minutes the phone call held.
Total cost = $0.95 + $0.18x
$2.75 = $0.95 + $0.18x
2.75 = 0.95 + 0.18x
2.75 - 0.95 = 0.18x
1.8 = 0.18x
1.8/0.18 = x
10 = x
Therefore, the call will go 10 minutes long.

Answer:
b^2 - 4ac ==> what's inside the square root
The answer is the 2nd option
Step-by-step explanation:
b^2 - 4ac represents the number of roots in the quadratic equation. If
b^2 - 4ac>0, then there are 2 roots in the quadratic equation. If
b^2 - 4ac=0, then there is only 1 root. If b^2 - 4ac<0, then the square root of b^2 - 4ac would be invalid since the square root of a negative number has no real solution. Hence, if b^2 - 4ac<0, then there are no roots.
Answer:
The answer should be option B. b^2-4ac

Divide. Rationalize all denominators. ∛6 x² y⁴ / 2∛5 x⁷y
The value of the expression [tex]\frac{x^{2}y^{4}}{2\sqrt[3]{5} x^{7}y}[/tex] after rationalizing the denominator is [tex]\frac{5^{\frac{2}{3}}y^{3}}{10x^{5}}[/tex].
A finite collection of symbols that is well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression.
Rationalizing the denominator is the process of shifting a root, such as a cube root or a square root, from the fraction's denominator to its numerator (numerator).
The numerator is the part of a fraction that comes before the vinculum.
The denominator of a fraction is the phrase that comes before the vinculum.
Consider the expression,
[tex]\frac{x^{2}y^{4}}{2\sqrt[3]{5} x^{7}y}[/tex]
Now, let [tex]a=\frac{x^{2}y^{4}}{2\sqrt[3]{5} x^{7}y}[/tex]
[tex]a=\frac{(x^{2}y)(y^{3})}{2\sqrt[3]{5} (x^{2}y)(x^{5})}[/tex]
[tex]a=\frac{y^{3}}{2\sqrt[3]{5} {~}x^{5} }[/tex]
To rationalize the denominator we multiply and divide the expression by ( ∛5 )².
[tex]a=\frac{y^{3}}{2\sqrt[3]{5} {~}x^{5} } \times \frac{(\sqrt[3]{5})^{2}}{(\sqrt[3]{5})^{2}}[/tex]
[tex]a=\frac{5^{\frac{2}{3}}y^{3}}{10x^{5}}[/tex]
The value of the expression when rationalized [tex]\frac{x^{2}y^{4}}{2\sqrt[3]{5} x^{7}y}[/tex] is [tex]\frac{5^{\frac{2}{3}}y^{3}}{10x^{5}}[/tex].

One less than four times a number is 11.
(Could you also help me solve the question too?)
Answer:
3
Step-by-step explanation:
Let's put that number as x.
It says that one minus 4 times x is 11.
So the equation is 4x - 1 = 11.
Add one on both sides to get 4x = 12.
Divide by four on both sides to get x = 3.
Since x is what we are looking for, the answer is 3!

The given expression written in surd form is 15√15
From the question, we are to write the given expression in surd form
The given expression is
[tex]15^{3/2}[/tex]
To write the expression is surd form, we will apply one of the laws of indices.
From one of the laws of indices, we have that
[tex]x^{y/n} = \sqrt[n]{x^{y} }[/tex]
Then,
We can write [tex]15^{3/2}[/tex] as
[tex]15^{3/2} = \sqrt[2]{15^{3} }[/tex]
[tex]= \sqrt[]{15^{3} }[/tex]
Simplifying
[tex]\sqrt{3375}[/tex]
Further simplification
[tex]\sqrt{225 \times 15}[/tex]
= [tex]\sqrt{225} \times \sqrt{15}[/tex]
= [tex]15 \times \sqrt{15}[/tex]

A grocery store sells a bag of 8 oranges for $3.12. If Boubacar spent $2.34 on oranges, how many did he buy
Answer:
Step-by-step explanation:
Answer = 6 oranges
.39 x 6 = $2.34
The number of oranges Boubacar buys is 6 oranges
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The number of oranges a grocery store sells at $ 3.12 = 8 oranges
The number of oranges a grocery store sells at $ 1.00 =
The number of oranges a grocery store sells at $ 3.12 / 3.12
The number of oranges a grocery store sells at $ 1.00 = 8 / 3.12
Now ,
The number of oranges a grocery store sells at $ 2.34 = The number of oranges bought by Boubacar
The number of oranges a grocery store sells at $ 2.34 = ( 8 / 3.12 ) x 2.34
So ,
The number of oranges bought by Boubacar = ( 8 / 3.12 ) x 2.34
= 8 x 0.75
= 6 oranges
Hence , the number of oranges Boubacar buys is 6 oranges

Just use a calculator.
First substitute in the numbers and make sure to use ( ) when plugging in negative values. For example, the first one says n=4, you can substitute n from the expression to 4. So n^2 + 3n + 8 will turn into 4^2 + 3(4) + 8 which is 16 + 12 + 8 = 36. You can do this with the other questions.

Solve by factoring. Check your answers. x²=-x+6
The factoring of the expression x²=-x+6 is (x-2)(x+3)
By ordering the values, we get:
x² + x - 6 = 0
To solve this exercise, we have to follow the rules of factoring:
1. Looking for the a and b number that state the following equations:
a + b = 1a * b = - 6Analyzing that (a*b) is a negative number, it means that (a) and (b) have different signs, and due to the results of (a+b) is positive the higher number has to be the positive one.
The number could be:
a = -2
b = 3
Confirming:
a + b = -2 + 3 = 1
a * b = (-2) * 3 = - 6
2. Rewriting the factored expression (x+a)(x+b) with the obtained values, we get:
(x-2)(x+3)
What is factoring?Is a technique that consist of decomposition of a factor into a product of another factor, which when multiplied together give the original number.
