Answer:
.87 g/ mL
Step-by-step explanation:
Density = mass over volume
We have a mass of 43.5 grams and a volume of 50 mL
Density = 43.5g / 50 mL
Density = .87 g/ mL

Answer:
(-4,1)
Step-by-step explanation:
Ordered pair (-4,1) means that x = -4 and f(x) = 1
Ordered pair (1,-4) means that x = 1 and f(x) = -4
From the table, we can see that the function is already defined for x = -4, but it is not defined for x = 1. So, the point (1,-4) can be included into the function, but the point (-4,1) cannot.
Use the below regular hexagon to answer the below questions. Each side is 12 cm long
a. Find the perimeter.
b. Find the apothem length.
C. Find the area.
Answer:
a. 72 cm
b. 12 cm
c. 144
Step-by-step explanation:
a. Perimeter is addition of all the sides so, 12 + 12 + 12 + 12 + 12 +12= 72.
b. Apothem is the length from the midpoint to a side so, it is 12.
c. Area is base times height so, 12 times 12 equals 144.

Look at the figure below.
What is the measure of Angle ACB
Hey there!
Since these angles share the same vertex (point where the lines that make the angle meet), they are congruent (they have the same value). Therefore, we can write the following equation.
4x-12=2x+48
We add 12 to both sides.
4x=2x+60
We subtract 2x from both sides.
2x=60
We divide both sides by 2.
x=30
Now, we can plug this in to find the measure of angle ACB. Whenever you see an angle that is named with three letters, the middle one is its vertex and the other two are the end points.
m∠ACB=4(30)-12
m∠ACB=120-12
m∠ACB=108

Here is a list of numbers:
47, 22, 22, 13, 77, 8, 18 ,100 ,70 ,4
Calculate the range.
Answer:
The range is 96.
Step-by-step explanation:
The definition of range is "The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set." So subtract the highest value from the smallest value, and you get 96. pls mark brainliest.
Hope this helps.
Hello !
first, we need to find the smallest and the biggest number on the list:
4, 8, 13, 18, 22, 22, 47, 70, 77, 100
so it's 4 and 100
we substract the smallest from the biggest number :
100 - 4 = 96
96 is the range

Gabriel wants to paint the model. How
much paint will he need?
The area of the square base is in.?
The area of each triangular face is
in.
Gabriel will need in.2 of paint.
Answer:
The area of the base is 144 square inches.The area of each triangular face is 66 square inches.Grabiel needs 408 square inches of paint.Step-by-step explanation:
The complete problem is attached.
Notice that the figure is a square pyramid, where its base dimensions are 12 inches by 12 inches, which represents an area of
[tex]B=12 \times 12 = 144 \ in^{2}[/tex]
The slant height of the pyramid is 11 inches, which allow us to find the area of each triangle face
[tex]A=\frac{1}{2}bh =\frac{1}{2}(12)(11)= 66 \ in^{2}[/tex]
But there are four triangle faces, so [tex]A_{faces} =4(66)=264 \ in^{2}[/tex].
Therefore, the area of each triangular face is 66 square inches.
So, the total surface area would be the sum
[tex]S=144+264=408 \ in^{2}[/tex]
Therefore, Gabriel needs 408 square inches to paint the whole model.
Answer:
144 66 408

Which polygons are similar??

Step-by-step explanation:
A $5,000 principal is invested in two accounts, one earning 1% interest and another earning 6% interest. If the total interest for the year is $170, then how much is invested in each account?
Answer:
$2600 was invested on the 1% account while $2400 was invested on the 6% account.
Step-by-step explanation:
For simple interest we must apply the following formula:
M = C*r*t
Where M is the amount of interest generated, C is the invested money, r is the rate of interest and t is the elapsed time.
The sum of capital investead in each account, "x" for the 1% interest one and "y" for the 6% interest one, must be equal to the original $5000. The same way as the interest generated from these investments must be equal to the earnt $170. So we have:
x + y = 5000
For the first account:
M1 = x*0.01*1 = 0.01*x
For the second account:
M2 = y*0.06*1 = 0.06*y
The sum of interests:
0.01*x + 0.06*y = 170
We have a system of equations as shown below:
x + y = 5000
0.01*x + 0.06*y = 170
Multiplying the first equation by -0.01 and adding both equations we have:
-0.01*x - 0.01*y = -50
0.01*x + 0.06*y = 170
0.05*y = 120
y = 120 / 0.05 = $2400
x = 5000 - 2400 = $2600
$2600 was invested on the 1% account while $2400 was invested on the 6% account.

Two angles in a triangle measure 102 degrees and 67 degrees. What is the measure of the third angle?
11 degrees
78 degrees
113 degrees
169 degrees
Answer:
11 degrees
Step-by-step explanation:
The sum of the interior angles of a triangle is 180 degrees.
From 180 degrees we subtract the sum of 102 degrees and 67 degrees, obtaining 11 degrees (first answer choice)

What is the vertex of this quadratic equation? Y=2(x-2)^2+5
Answer:
vertex = (2, 5 )
Step-by-step explanation:
The equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
y = 2(x - 2)² + 5 ← is in vertex form
with (h, k) = (2, 5 ) ← vertex

what is the simplest form for this ratio?
7 : 11
Answer:
7/11
Step-by-step explanation:
Answer:
7 : 11 = 7 /11
Solution:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 7 and 11 is 1
Divide both terms by the GCF, 1:
7 ÷ 1 = 7
11 ÷ 1 = 11
The ratio 7 : 11 cannot be reduced further by dividing both terms by the GCF = 1 :
This ratio is already in lowest terms.
Therefore:
7 : 11 = 7 /11
