Answer:
B - 1/9
Step-by-step explanation:
I don't really know how to explain how I got it because I'm only in middle school in pre-algebra, but I did teach this to myself online haha, so here we go. Daneille rolled the dice 90 times, it only landed on 6 10 times. That is 10/90 which, simplified, is 1/9.
Find the unknown sides and angles of this triangle using the Law of Cosines. Round to the nearest hundredth.
Step-by-step explanation:
as we know
law of cosine
[tex]c = \sqrt{ {a}^{2} + {b}^{2} - 2ab. \cos(c) } [/tex]
[tex]c = \sqrt{ {14}^{2} + {18}^{2} - 2.14.18 - \cos( {35}^{o} ) } [/tex]
[tex]c = 10.35[/tex]
using the law of cosine
[tex]cos(a) = \frac{ {b}^{2} + {c}^{2} - {a}^{2} }{2bc} [/tex]
[tex] \cos(a) = \frac{ {18}^{2} + {10.35 }^{2} - {14}^{2} }{2.18.(10.35)} [/tex]
[tex]a = {50.87}^{o} [/tex]

We went to the store and bought 6 giant candy bars and 2 small
bags of jawbreakers and spent $13.00. My friend went to the store
and bought 4 giant candy bars and 6 small bags of jawbreakers
and spent $11.00. How much did a candy bar cost? How much did
a bag of jawbreakers cost?
Answer:
Giant Candy Bar: 2$
Small Bags of Jawbreakers: .50$
Step-by-step explanation:
First you make out the equations, with the variables of c for giant candy bars and j for the small bags of jaw breakers.
First equation we make is 6c+2j=13
The second equation is 4c+6j=11.
You can then make one of the equations a negative and equal to the other. What I mean is we can use the elimination method. So I choose to do -18c+-6j=-39 (Multiplied by -3) so we can eliminate the 2 6js and get 4c=11 and -18c=-39. You then add the remaining equations together to get -14c=-28, so c=2. Using that we can then chose an equation to substitute c with. Ill choose the first one, so you get 6(2)+2j=13. 12+2j=13; 2j=1. By simplifying, you get the jawbreakers as .50 dollars.
A milk tank at a dairy farm has the form of a rectangular prism. The tank is 3.5 feet wide. The width of the tank is 5/7 of its length, and the height is 4/5 of its width. How many cubic feet of milk can the tank hold? How many pounds of milk can it hold if 1 cubic foot of milk weighs 66.5 lbs?
Answer:
48.02 or 48 1/50 cubic feet and 3193.33 or 3193 33/100 LB ( I do rsm too )
Step-by-step explanation:
The width is 3.5
The length is 3.5*7/5 which is 4.9
The height is 4/5 of 3.5 which is 2.8
So, the volume in cubic feet is 3.5*4.9*2.8 which is 48.02 or 48 1/50
So, the amount in Lb is 66.5*48.02 which is 3193.33 or 3193 33/100
A tank can hold [tex]\boldsymbol{24.5}[/tex] cubic feet of milk and a tank can hold [tex]\boldsymbol{1629.25}[/tex] pounds.
Rectangular prismA rectangular prism is a three-dimensional solid object that has six rectangle-shaped faces.
Length of a rectangular prism [tex](l)=3.5[/tex] feet
Width of a rectangular prism [tex](w)=\frac{5}{7}(3.5)[/tex]
[tex]=2.5[/tex] feet
Height of a rectangular prism [tex](h)=\frac{4}{5}(3.5)[/tex]
[tex]=2.8[/tex] feet
Volume of a milk tank [tex]=lwh[/tex]
[tex]=3.5(2.5)(2.8)[/tex]
[tex]=\boldsymbol{24.5}[/tex] cubic feet
[tex]=24.5(66.5)[/tex] pounds
[tex]=\boldsymbol{1629.25}[/tex] pounds
So, a tank can hold [tex]\boldsymbol{24.5}[/tex] cubic feet of milk and a tank can hold [tex]\boldsymbol{1629.25}[/tex] pounds.

What is the solution to the system of equations below?
y=-3x+6 and x = -6
O (-6,8)
O (6,4)
O (8,6)
O (4, 6)
Answer:
The solution to the system of equations will be: (-6, 24)
Step-by-step explanation:
Given the system of equations
y = -3x+6
x = -6
substituting x = -6 in the equation y = -3x+6
y = -3x+6
y = -3(-6) + 6
y = 18+6
y = 24
Therefore, the solution to the system of equations will be: (-6, 24)
Note: it seems you have not mentioned the correct option in the answer choice as the correct choice is (-6, 24).

IF THE VOLUME OF THE BOX BELOW IS
x3 + 6x2 + 9x + 4
AND THE WIDTH OF THE BOX IS x + 4,
THEN FIND THE LENGTH AND HEIGHT OF
THE BOX
Answer:
The length of the box is (x + 1)
The height of the box is (x + 1)
Step-by-step explanation:
The given function representing the volume of the box is presented as follows;
V = x³ + 6·x² + 9·x + 4
The function representing the width of the box, W = x + 4
Therefore, we have;
(x³ + 6·x² + 9·x + 4)/(x + 4) = x² + 2·x + 1
x³ + 4·x²
[tex]{}[/tex] 2·x² + 9·x + 4
[tex]{}[/tex] 2·x² + 8·x
[tex]{}[/tex] x + 4
Therefore, we have;
(x³ + 6·x² + 9·x + 4) = (x + 4) × (x² + 2·x + 1) = (x + 4) × (x + 1) × (x + 1)
(x³ + 6·x² + 9·x + 4) = (x + 4) × (x + 1) × (x + 1)
The width of the box = (x + 4)
The length of the box = (x + 1)
The height of the box = (x + 1).

Answer:
The height of the triangle is: h = 6.4 cm
Step-by-step explanation:
Given
Area of the triangle A = 40 cm²
The Base of the triangle b = 12.5 cm
To determine
height of triangle h = ?
We know that the area A of a triangle is:
A = 1/2 bh
where
b is the baseh is the height of the triangle.so
A = 1/2 bh
substituting A = 40 and b = 12.5
40 = 1/2 (12.5) h
40 × 2 = 12.5 h
12.5 h = 80
divide both sides by 12.5
12.5h/12.5 = 80/12.5
h = 6.4 cm
Thus, the height of the triangle is: h = 6.4 cm

Answer:
No, X=7
Step-by-step explanation:
Answer:
Yes, both equations will always work, but yes, at times it is more logical to use one over the other. for instance:
x-4y=6
x+4y=12
we see here that elimination would best fit:
x+x+4y-4y=6+12
or:
x=2y-3
7x+3y-81=23
substitute (2y-3) for x.
Also, once you have a single placeholder, put it ito quadratic form (ax^2+bx+c=0)
and use the quadratic formula:
x=(-b±sqrt(b^2-4ac))/2a
When Mariana does 19 push-ups and 6 sit-ups, it takes a total of 75 seconds. In comparison,
she needs 72 seconds to do 18 push-ups and 6 sit-ups. How long does it take Mariana to do
each kind of exercise?
HELP
Answer: It takes 3 seconds to do one of both i think
Step-by-step explanation:
19 and 6 was 75 and 18 and 6 was 72 which means 1 push up is 3 seconds multiply 3 by 18 that is 54 then subtract 72 by 54 which gives you 18 then divide 18 by 6 which is 3
