Answer:
[tex]13.51\ \text{s}[/tex]
Step-by-step explanation:
[tex]s[/tex] = Average speed of Sandra = [tex]7.4\ \text{m/s}[/tex]
[tex]d[/tex] = Distance Sandra ran = [tex]100\ \text{m}[/tex]
Time is given by
[tex]t=\dfrac{d}{s}[/tex]
[tex]\Rightarrow t=\dfrac{100}{7.4}[/tex]
[tex]\Rightarrow t=13.51\ \text{s}[/tex]
The time it takes Sandra to run the given distance is [tex]13.51\ \text{s}[/tex].
Which expression has the greatest value?
Answer:
the last one
Step-by-step explanation:
[tex]\sqrt[3]{64}[/tex] and [tex]16^{3/2}[/tex] expressions have the greatest value.
What is square root and cube root of a number?
Square root of a number results a number that when square, gives us the previous number.
Similarly, cube root of a number results a number that when cubed, gives us the previous number.
Here, [tex]\sqrt[3]{64}[/tex]² = ∛(64 × 64) = ∛(8 × 8 × 8 × 8 × 8 × 8) = 8 × 8 = 64
[tex]16^{3/2}[/tex] = 4³ = 64
[tex]\sqrt[3]{8^{4} }[/tex] = ∛(8 × 8 × 8 × 8) = ∛(64 × 64) = ∛(4 × 4 × 4 × 4 × 4 × 4) = 4 × 4 = 16
√(16²) = √(16 × 16) = 16
Therefore, [tex]\sqrt[3]{64}[/tex]² and [tex]16^{3/2}[/tex] have the greatest value.

Katherine buys a tv with a normal price of $200 and she has a 25% off coupon. How much money did she save????
Given:
Normal price of a tv = $200
Coupon = 25% off
To find:
The money saved by Katherine.
Solution:
Katherine buys a tv with a normal price of $200 and she has a 25% off coupon. It means, the money saved by Katherine is 25% of normal price of tv, i.e., $200.
[tex]Saving=25\%\text{ of }200[/tex]
[tex]Saving=\dfrac{25}{100}\times 200[/tex]
[tex]Saving=25\times 2[/tex]
[tex]Saving=50[/tex]
Therefore, the money saved by Katherine is $50.

2x + 3 = -7 what is x
Answer: x=-5
Step-by-step explanation:
You would have to do the inverse to “undo” the equation.
So first you would do -7-3=-10
Then you would do -10/2=-5 to find x
Given the equation of a line y = 5x -16, what is the slope of a line PERPENDICULAR to this line?
Answer:
[tex]-\frac{1}{5}[/tex]
Step-by-step explanation:
Notice that the equation y = 5x - 16 is in slope-intercept form, or [tex]y = mx + b[/tex] format. Whenever an equation is in slope-intercept form, the number in place of the [tex]m[/tex], or the coefficient of the x-term, represents the slope of that line. So, the slope of the given line is 5.
Slopes that are perpendicular to each other are opposite reciprocals. So, we need to find the opposite reciprocal of 5. To do that, write it as a fraction, making it [tex]\frac{5}{1}[/tex]. Then, switch the sign and flip the numerator and denominator. This means that the opposite reciprocal of 5 is [tex]-\frac{1}{5}[/tex], so [tex]-\frac{1}{5}[/tex] is the perpendicular slope.
What is the inverse of the function below?

Which statement is true about the purpose of trend lines in scatterplots? A trend line must pass through the largest data point. A trend line must pass through the smallest data point. A trend line can be used to make predictions in real-world situations. A trend line shows the exact data points collected.
Answer:
a trend line can be used to make predictions in real-world situations (the third option)
Explanation:
the first & second options are wrong because it is not a requirement for a trend line to pass through any given data point.
the fourth option is wrong because a trend line shows the general upward/downward trend of the data, and may not necessarily touch all of the data points.
the third option is correct because a trend line helps to roughly estimate the trend (hence the name) of the graph, which allows us to make predictions in real-world situations.

What is the equation of a line with a slope of 2 and a y intercept of -5?
Answer:
y=2x-5
Step-by-step explanation:
The slope is how you move so you could also call it m
The y intercept is where you begin so you could call it b
So every time you need to find the equation or which one is like the slope just remember m=move b= begin
y=mx+b
