Answer:
30 kilogram/cubic meter
Step-by-step explanation:
Answer:
mass=180kg and the volume=6m³.
then the formula to find density is= mass/volume
using this formula,180kg/6m³=30kg/m³
What is the Sector area with radius 6 and an angle of 50°? Use 3.14 for pi.
Answer:
15.7 units²
Step-by-step explanation:
The sector area is 50/360 times the area of the circle (since the central area of a complete circle is 360° and that for the sector is 50°), or
Sector area = (50/360)(3.14)(6 units)² = 15.7 units²
Jasmine swims 12 laps every afternoon, Monday through Friday. How many laps does she swim in one week?
Answer:

Write an equation of the line. Express the answer using either the general form or the slope-intercept form of the equation of a line.
Answer:
y=x-4
Step-by-step explanation:
The graph intercepts the y-axis at -4 and when you do rise over run you get 4/4 which is just equal to 1 so there would not be a coefficient in front if x

Graham earns $6 for every crate of oranges he picks.
Lynn earns $5 per hour babysitting.
How many crates of oranges does Graham need to pick to earn the same amount
that Lynn earns for 12 hours of babysitting?
Enter your answer in the box.
Graham needs to pick 10 more oranges to have the same amount I think
Step-by-step explanation:
so first multiply 5 and 12 which is 60
5*12=60
then divide 60 from 6 or 6 from 60
60÷6= 10

Describe lengths of three segments that could not be used to form a triangle. Segments with lengths of 5 in., 5 in., and ______ in. Cannot form a triangle.
Answer:
[tex]c = 11[/tex]
Step-by-step explanation:
Given
Let the three sides be a, b and c
Such that:
[tex]a = b= 5[/tex]
Required
Find c such that a, b and c do not form a triangle
To do this, we make use of the following triangle inequality theorem
[tex]a + b > c[/tex]
[tex]a + c > b[/tex]
[tex]b + c > a[/tex]
To get a valid triangle, the above inequalities must be true.
To get an invalid triangle, at least one must not be true.
Substitute: [tex]a = b= 5[/tex]
[tex]5 + 5 > c[/tex] [tex]===>[/tex] [tex]10 > c[/tex]
[tex]5 + c > 5[/tex] [tex]===>[/tex] [tex]c > 5 - 5[/tex] [tex]===>[/tex] [tex]c > 0[/tex]
[tex]5 + c > 5[/tex] [tex]===>[/tex] [tex]c > 5 - 5[/tex] [tex]===>[/tex] [tex]c > 0[/tex]
The results of the inequality is: [tex]10 > c[/tex] and [tex]c > 0[/tex]
Rewrite as: [tex]c > 0[/tex] and [tex]c < 10[/tex]
[tex]0 < c < 10[/tex]
This means that, the values of c that make a valid triangle are 1 to 9 (inclusive)
Any value outside this range, cannot form a triangle
So, we can say:
[tex]c = 11[/tex], since no options are given
What is the quotient of 5 1/2 ÷ 3/8?
Answer:
14 2/3
Step-by-step explanation:
It's easiest to convert 5 1/2 to the improper fraction 11/2.
Then the problem calls for dividing 11/2 by 3/8, which, in turn, is equivalent to
the product of 11/2 and 8/3:
11 8
---- * ----- = 88/6 or 44/3 or 14 2/3
2 3
Optionally you could convert to mixed decimal fractions:
5.5
---------- = 14 2/3 (same as before)
0.375

At an ice cream shop, 4 of the last 12 cones sold had chocolate ice cream. Considering this data, how many of the next 15 cones sold would you expect to have chocolate ice cream?
Answer:
5
Step-by-step explanation:
First, write the experimental probability as a fraction in simplest form.
P(chocolate)
=

We can predict the outcome of the second set of trials by assuming that the ratio will be the same as in the first set of trials. Write a proportion by setting the two ratios equal to each other, then solve.
1
3
=
n
15
1
3
(315)
=
n
15
(315) Multiply both sides by (315)
115
= 3n Simplify
15
= 3n Simplify
5
= n Divide both sides by 3
You would expect 5 of the next 15 cones sold to have chocolate ice cream.

Kris claims that the two figures must be congruent.
Two triangles have angles 100 degrees, 50 degrees, and 30 degrees.
Which statement best describes his claim?
He is correct because both figures are triangles.
He is correct because the measures of the angles are the same in both figures.
He is incorrect because the triangles are not oriented the same way.
He is incorrect because the lengths of the corresponding sides of the figures are unknown.

Answer:
[tex]x = 7 \sqrt{2} [/tex]
Step-by-step explanation:
[tex]sinθ = \frac{opp}{hyp} [/tex]
[tex]sin45° = \frac{7}{x} [/tex]
[tex] \frac{ \sqrt{2} }{2} = \frac{7}{x} [/tex]
Cross multiply:
[tex]( \sqrt{2} )(x) = 7(2)[/tex]
[tex]x = \frac{14}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } [/tex]
[tex]x = \frac{14 \sqrt{2} }{2} [/tex]
[tex]x = 7 \sqrt{2} [/tex]
What is the area of the rectangle with the given dimensions? *
The dimensions of a rectangle are 2x - 5 and
3x + 3. Which expression represents the area
of the rectangle in simplest terms?
F 6x2 - 9x - 15
G 6x2 - 9x + 15
H 6x + 9x - 15
J 6x - 15x - 9
Given:
The dimensions of a rectangle are [tex]2x-5[/tex] and [tex]3x+3[/tex].
To find:
The expression that represents the area of the rectangle in simplest terms.
Solution:
Area of a rectangle is:
[tex]Area=Length\times Width[/tex]
The dimensions of a rectangle are [tex]2x-5[/tex] and [tex]3x+3[/tex]. So, the area of the given rectangle is:
[tex]Area=(2x-5)\times (3x+3)[/tex]
[tex]Area=2x(3x)+2x(3)-5(3x)-5(3)[/tex]
[tex]Area=6x^2+6x-15x-15[/tex]
[tex]Area=6x^2-9x-15[/tex]
Therefore, the correct option is F, i.e., [tex]6x^2-9x-15[/tex].
