Step-by-step explanation:
Volume of displaced water = (10cm)(10cm)(1.6cm)
= 160 cm^3
density = mass/vol of displaced water
= 3088 grams/160 cm^3
= 19.3 g/cm^3

Amare is buying museum souvenirs. He buys 3 animal figures
and 6 bookmarks for $33. Later he goes back to buy 3 more
figures and return 3 of the bookmarks, spending another $6.
In the system, fis the price of a figure and b is the price
Al Pisto
of a bookmark.
3f + 6b = 33
3f-3b = 6
How much does each figure cost? How much does each bookmark cost?
Answer:
Each animal figure cost $2 dollars and each bookmark cost $4.50 dollars
Step-by-step explanation:
I got this answer is because second part of the question it says "Later he goes back to buy 3 more figures and return 3 of the bookmark spending another $6". The information this gives us is that since he bought nothing but animal figures and bought 3 animal figures and spent $6 dollars that tells us that each animal figure cost $2 dollar knowing this we can figure out the first part since in the first part he spent $33 dollars in total and bought 3 animal figures and 6 bookmarks and we know each animal figure cost $2 dollars we know in total he spent $6 dollar on animal figures and he spent $27 dollar on bookmarks doing division 27 divided by the number of bookmarks he bought we figure out the cost of one bookmark so doing this the answer is one animal figure is $2 dollars and one bookmark is $4.50.
I hope this help this is less of a math problem and more of a logic one this took me a while of rereading to figure out!

Answer:
∡B = 60°
Step-by-step explanation:
find BC using Pythagorean Theorem:
5² + BC² = 10²
25 + BC² = 100
BC² = 75
BC = [tex]\sqrt{75}[/tex]
BC = [tex]\sqrt{25}[/tex][tex]\sqrt{3}[/tex] which is 5[tex]\sqrt{3}[/tex]
this indicates that ∡B must be 60° because the ratio of sides in a 30-60-90 triangle are 1 : [tex]\sqrt{3}[/tex] : 2

if y = 20 and x = 2, what is the value of y when x = 10 ?
Step-by-step explanation:
y=k/x
y=20, x=2
Substitute this first to get "k"
20=k/2
k=40
Value of y when x=10... is now
y= 40/10
y=4.
PLS HELP ASAP, given angle m ABD is a straight angle.
Answer:
measure of CBD is 125 degrees
Step-by-step explanation:
ABC + CBD is equal to 180 degrees
8x - 41 + 9x + 17 = 180
combine like terms
17x - 24 = 180
add 24 to both sides
17x = 204
divide both sides by 17
x = 12
then plug in to find CBD
9 (12) + 17
108 + 17 = 125 degrees
Answer:
angle CBD = 125°
Step-by-step explanation:
Because ABD is a straight angle we know it is equal to 180°
because we have this information we can create the equation
(8x-41) + (9x+17) = 180
17x - 24 = 180
(here you would add 24 to both sides)
17x = 204
(divide both sides by 17)
x = 12
Then you would plug in 12 for x in the equation for CBD which will then get you 125°
Quadrilateral ABCD is given with ∡A=35°, ∡B=40°, ∡C=(5x+5)°, and ∡D=(5x)°. What is the value of x?
A. x = 6
B. x = 10
C. x = 28
D. x = 7
Answer:
C) x = 28
Step-by-step explanation:
35 + 40 + 5x+5 + 5x = 360
10x + 80 = 360
10x = 280
x = 28

Describe the likehood of the event given its probability .you make a free throw 70 percent of the time
IMPOSSIBLE
LIKLEY
POSSIBLE
Answer:
possible
Step-by-step explanation:
the question asks what is the likelyhood of making a free throw 70% of the time, whcih is possible beacuase you can make it, you can also miss it. there are several professional basketball players that have that percentage. but it is not likely that someone could just shoot 70 percent. so i would stick with possible

The Anderson family paid $53 to have four pizzas delivered. Five pizzas would cost $65 and 6 pizzas would cost $77. Write an equation to represent the total cost, y, of x pizzas delivered.
Answer:
The equation is:
[tex]y =12x+5[/tex]
Step-by-step explanation:
Given
[tex](x,y) = (Pizza,Cost)[/tex]
So, we have:
[tex](x_1,y_1) = (4,53)[/tex]
[tex](x_2,y_2) = (5,65)[/tex]
[tex](x_3,y_3) = (6,77)[/tex]
Required
Equation to represent the scenario
First, calculate the slope
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
So, we have:
[tex]m = \frac{65 - 53}{5 - 4}[/tex]
[tex]m = \frac{12}{1}[/tex]
[tex]m=12[/tex]
So, the equation is:
[tex]y =m(x - x_1) + y_1[/tex]
This gives:
[tex]y =12(x - 4) + 53[/tex]
[tex]y =12x - 48 + 53[/tex]
[tex]y =12x+5[/tex]

if the center of a circle is (-5, -8) and contains the point (16, 68) what is the equation ?
Answer:
[tex](x+5)^2+(y+8)^2=6217[/tex]
Step-by-step explanation:
Hi there!
Equation of a circle: [tex](x-h)^2+(y-k)^2=r^2[/tex] where the circle is centered at (h,k) and r is the radius
1) Plug the center of the circle into the equation
Center: (-5,-8)
[tex](x-h)^2+(y-k)^2=r^2\\(x-(-5))^2+(y-(-8))^2=r^2\\(x+5)^2+(y+8)^2=r^2[/tex]
2) Determine r²
Plug in the given point (16,68)
[tex](x+5)^2+(y+8)^2=r^2\\(16+5)^2+(68+8)^2=r^2\\(21)^2+(76)^2=r^2\\441+5776=r^2\\6217=r^2[/tex]
Therefore, r² is equal to 6217. Plug this back into [tex](x+5)^2+(y+8)^2=r^2[/tex]:
[tex](x+5)^2+(y+8)^2=6217[/tex]
I hope this helps!

Answer:
B. y ≤ –3x + 5
Step-by-step explanation:
Its B, all y-values are less than -3x+5. also consider root by setting -3x+5=0
x=5/3 is positive so its the second one
...................................................................................................................................................
Answer:
Step-by-step explanation:
we know that
The solution of the inequality is the shaded area below the solid line (the gray area)
The slope of the solid line is negative
The y-intercept of the solid line is positive
The equation of the solid line is equal to
therefore
the equation of the inequality is equal to
If a1 = 7 and an = An-1 – 3 then find the value of a4.
Answer:
-2
Step-by-step explanation:
If a1 = 7 and an = An-1 – 3
a4 = a3 - 3
Get a2;
a2 = a1 - 3
a2 = 7 - 3
a2 = 4
Get a3;
a3 = a2 - 3
a3 = 4 - 3
a3 = 1
GEt the required a4
a4 = a3 - 3
a4 = 1 - 3
a4 = -2
Hence the value of a4 is -2

Does the point (2,-1) lie on the line
y=3-2x?
Answer:
yes
Step-by-step explanation:
the line passes through that point.
Answer:
yes
Step-by-step explanation:
Here, x=2 and y=-1
If these points lie on the line y= 3-2x,then they must satisfy the equation of the line (also mean they must be equal)
So on solving the equations putting the value of x and y, we get
y=3-2x
or,-1=3-2*2
or,-1=3-4
Therefore, -1=-1
