Evaluate: (9 - 3)² + 5 ÷ ⅓
Answer:
123
Step-by-step explanation:
(6^2+5)*3= 41*3= 123
Answer:
Step-by-step explanation:
take away the parenthesis
9 - 3 = 6
6² + 5 ÷ ⅓
take away the exponents
6 * 6 = 36
36 + 5 ÷ ⅓
36 + 5 = 41
41 ÷ ⅓
( 41 ÷ 1 ) ÷ 3
41 ÷ 3

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.
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
A car traveled 25 miles of a 200 mile trip to its destination. The car travels at a speed of 35 miles per hour. How many hours until the car reaches its destination? Respond to the two questions below and show all work.
Answer: 5 hours
Step-by-step explanation:
The car has already travelled 25 miles into the 200 miles that it is meant to travel.
The distance left is therefore:
= 200 - 25
= 175 miles
The car is travelling at 35 miles per hour.
The time left for travel is:
= Distance / Speed
= 175 / 35
= 5 hours

Solve the system of equations using subtraction. y = -2x + 1 4x + 2y = -3 a. Infinity many solutions b. No solution c. (0,-5) d. (-5,0)
Given:
The given system of equation is:
[tex]y=-2x+1[/tex]
[tex]4x+2y=-3[/tex]
To find:
The solution of given system of equations using subtraction.
Solution:
We have,
[tex]y=-2x+1[/tex] ...(i)
[tex]4x+2y=-3[/tex] ...(ii)
First equation can be rewritten as
[tex]2x+y=1[/tex] (Adding 2x on both sides)
[tex]4x+2y=2[/tex] ...(iii) (Multiplying both sides by 2)
After subtracting (ii) from (iii), we get
[tex]4x+2y-(4x+2y)=2-(-3)[/tex]
[tex]4x+2y-4x-2y=2+3[/tex]
[tex]0=5[/tex]
This statement is false because [tex]0\neq 5[/tex]. It means, there is no value of x and y for which the given system of equations are true.
Therefore, the given system of equations has no solution and the correct option is b.

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]

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:
12.68
Step-by-step explanation:
With reference angle 45°
perpendicular (p) = 9
hypotenuse (h) = c
Now
sin 45 ° = p/ h
0.71 = 9 / c
c = 9 / 0.71
c = 12.68

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).

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

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
