If necessary, round your answer to the nearest tenth.
Answer:
11
Step-by-step explanation:
Answer:
11.4 (This is already rounded to the nearest tenth)
Step-by-step explanation
1.) Add all of them
17+7+13+17+7+9+10=80
2.) Divide the sum by how many numbers there are
In this case, there are 7, so 80/7 is 11.42...
3.) Get the answer
80.7 simplifies into 11.42 so rounded to the nearest 10th is 11.4.

Ms. Benson is making a jewelry box using 2 identical squares of wood and 4 identical rectangular pieces of wood, as shown below.
What is the surface area of the jewelry box in square inches (sq. in)?
Length of rectangles = 7 in.
Breadth of 4 rectangles = 3 x 4
= 12 in.
Side of squares = 3 in.
Area of 4 rectangles = length x breadth
= 7 x 12
= 84 sq. in.
Area of two squares = 2(side x side)
= 2(3 x 3)
= 18 sq. in.
Therefore, Surface area of the Jewellery box = 84 sq. in. + 18 sq. in.
= 102 sq. in.

At a birthday party, Vivian counts 15 vanilla ice cream cups and 25 chocolate ice cream cups. Which properties can be used to determine the percent, p, of the ice cream that is chocolate?
Answer:
62.5 %
Step-by-step explanation:
The percentage, p of the ice cream that is chocolate is p = total number of chocolate ice cream cups/total number of ice cream cups × 100%
Given that there are 25 chocolate ice cream cups and 15 vanilla ice cream cups, total number of ice cream cups = 25 + 15 = 40
So, p = total number of chocolate ice cream cups/total number of ice cream cups × 100%
p = 25/40 × 100%
p = 25/4 × 10 %
p = 6.25 × 10 %
p = 62.5 %
Anil scored 30 runs in the first innings of a test match. His score changed by +30 runs in the second innings. What was his score in the second innings?
Answer:
60 runs
Step-by-step explanation:
Given that:
Score in first innings = 30 runs
Change in score during second inning = + 30
The score in the second inning will be :
Score in first inning + change in score during second inning
30 + (+30)
30 + 30
= 60 runs
Major arc CBD measures 300 degrees. Which is the radian measure of its corresponding central angle? O 4 pie/3 O 5 pie/6 O 5 pie/3 O 11 pie/6
Answer:
[tex]\dfrac{5\pi}{3}[/tex]
Step-by-step explanation:
Given that,
Major arc CBD measures 300 degrees.
We need to find the radian measure of its corresponding central angle.
Radian measure is given by :
[tex]R=\dfrac{\pi}{180}\times d\\\\R=\dfrac{\pi}{180}\times 300\\\\R=\dfrac{5\pi}{3}[/tex]
So, the radian measure is [tex]\dfrac{5\pi}{3}[/tex].

The momentum of a variable is represented by the rate of change. The rate of change for the situation is 3 miles per hour.
What is the rate of change?The momentum of a variable is represented by the rate of change, which is used to quantitatively express the percentage change in value over a specific period of time.
Given the distance covered in one hour is 3 miles, while the distance covered in 2 hours is 6 miles. In the given case, the rate of change for the situation, therefore,
Rate of change = (6miles-3miles)/(2hours-1hour) = 3miles/hour.
Hence, the rate of change for the situation is 3 miles per hour.

Write the equation of the line that passes through the points (1,-4) and (4, -5).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line
Answer:
[tex]y+4 = -\frac{1}{3} (x-1)[/tex]
Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope. Substitute the x and y values of the given points into the formula and solve:
[tex]m = \frac{(-5)-(-4)}{(4)-(1)} \\m = \frac{-5+4}{4-1} \\m = \frac{-1}{3}[/tex]
So, the slope is [tex]-\frac{1}{3}[/tex].
2) Use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line in point-slope form. Substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] into the formula.
Since [tex]m[/tex] represents the slope, substitute [tex]-\frac{1}{3}[/tex] in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point on the line, choose any one of the given points (it doesn't matter which one) and substitute the x and y values of it into the formula. (I chose (1,-4), as seen below). This gives the equation of the line in point-slope form.
[tex]y-(-4) = -\frac{1}{3} (x-(1))\\y+4 = -\frac{1}{3} (x-1)[/tex]

For what values of t can 2x^2+tx+10 be written as the product of two binomials?
The value of t for which the given expression 2x²+tx+10 will be a product of two binomial is 9.
What is binomial?A binomial expression is an expression that has two terms.
In order to get the value of t for which the given expression 2x²+tx+10 will be a product of two binomial. We need to find a number(A) that is when broken into two other numbers(B and C), the sum of these numbers(B and C) is the number itself(A). Also, the product of the two numbers is equal to the product of the rest two terms of the expression(2 and 10).
Therefore, the number that fulfills this condition is 9. Let's check by substituting the value of t as 9.
[tex]2x^2+tx+10\\\\= 2x^2+9x+10 \\\\= 2x^2+5x+4x+10\\\\ = x(2x + 5)+2(2x+5)\\\\= (x+2)(2x+5)[/tex]
Hence, the value of t for which the given expression 2x²+tx+10 will be a product of two binomial is 9.
