Brenda’s scores on the first three of four 100-point science tests were 95, 92, and 89. What score does she need on her fourth science test to ensure an average score of at least 93?. . A) X ≥ 96. B) X ≤ 90. C) X ≥ 88. D) X ≤ 92
Answers
95 + 92 + 89 + x ≥ 93 * 4 where 4 is the number of data points.
x ≥ 96. Test score should be equal or greater than 96.
4 scores
(95+92+89+x)/4>93
times 4 both sides
276+x>372
minus 276 both sides
x>96
A

Answer:
True
Step-by-step explanation:
The formula for the circumference of a circle is:
C=2πr
So we can substitute in the numbers we have:
Radius=4, so:
C=8π (we multiplied the radius by 2)
So the statement is true.

Answer:
True
Step-by-step explanation:
The circumference (C) of a circle is
C = 2πr ← r is the radius
For C = 8π, then
2πr = 8π ( divide both sides by 2π )
r = 8π ÷ 2π = 4
Hence the radius must be 4

Answer:
Standard form = 496,660,342,811.
Step-by-step explanation:
Standard form is a way of writing down very large or very small numbers easily.
- To convert small normal numbers into standard form.
- Find the first non 0 digit after the decimal point.
- After this digit, place your new decimal point ignoring everything that is in front of this digit.
General form:
400,000,000,000 + 90,000,000,000 + 6,000,000,000 + 600,000,000 + 60,000,000 + 300,000 + 40,000 + 2,000 + 800 + 10 + 1
Standard form:
Ans = 496,660,342,811.
if you input into a calculator and count the decimal from the end to the left it should give you your answer
p.s. that was a bad explanation, im sorry

Circle radius = 2.75 m
People's reach = 1.5m
Get the area of the circle.
A = π r² ⇒ 3.14 * (2.75m)² ⇒ 3.14 * 7.5625m² = 23.75 m²
Get the area of the inner circle:
r = 2.75 m - 1.5 m = 1.25 m
A = 3.14 * (1.25m)² ⇒ 3.14 * 1.5625 m² = 4.91 m²
Subtract the area of the inner circle from the total area to get the area that people can reach.
A = 23.75 m² - 4.91 m² = 18.84 m²

The compound inequality that represents each situation is –6 < x < 6.
Let's consider the given situation step by step. We know that the numbers should be greater than -6, so we can use the symbol "x > -6" to represent this condition. Additionally, we need the numbers to be less than 6, which can be represented as "x < 6."
Now, we need to combine these two inequalities to represent the whole situation. Since we want both conditions to be true, we should use the "and" condition, which is represented by the symbol "∧" or simply by writing the inequalities side by side.
So, the compound inequality representing the given situation is:
-6 < x < 6
In this compound inequality, x represents any real number that is greater than -6 and less than 6. This means that the numbers between -6 and 6, excluding -6 and 6 themselves, are the solution set for this compound inequality.
Graphically, this can be represented on a number line. We draw a line and mark -6 with an open circle and draw an open circle at 6 as well. Then, we shade the region between -6 and 6 to show that all real numbers within this range satisfy the compound inequality.
So, the correct option is (c).
