Answer:
15
Step-by-step explanation:
it all comes down to 7x-1
then set that equal to 106 so it looks like 7x - 1 =106
106 - 1 = 105
105/7 = x
x = 15

Answers
Answer:
x=7, y=9. (7, 9).
Step-by-step explanation:
-3x+y=-12
5x-2y=17
---------------
y=-12-(-3x)
y=-12+3x
y=3x-12
5x-2(3x-12)=17
5x-6x+24=17
-x+24=17
-x=17-24
-x=-7
x=7
y=3(7)-12
y=21-12

What’s the area??
BTW THE ANSWER IS NOT 78
Answers
Answer:
She shaded area?
12 x 10 = 120
6 x 7 = 42
42 divided by 2 = 21
Now we subtract both areas:
120 - 21 = 99 of the shaded region.
Answer:
99
Step-by-step explanation:
7 * 6 is 42 then divide by 2 = 21
12 * 10 is 120
120 - 21 = 99
1. You have a 16m by 24m rectangular area in your garden. You want to use it
to construct a swimming pool. The swimming pool will have a surrounding
foot path of 2m. If it costs $3 per square meters to tile the footpath, How
much will it cost to tile the entire footpath?
2m
2m
16 m
24 m

Answers
Answer:
Total cost of footpath = 528 m²
Step-by-step explanation:
Width of footpath is 2m.
Thus,
For longer footpath, there will be two sides. Thus; area = 2(24 + 2 + 2) × 2 = 112 m²
For shorter footpath, since the 2 longer sides have been taken care of, length remains 16m. Then area = 2(16 × 2) = 64 m²
Total area = 112 + 64 = 176 m²
cost to tile foot path is $3 per square metres.
Total cost of footpath = 176 × 3
Total cost of footpath = 528 m²

2. The length of a rectangle is 18 centimeters and the width is 6 centimeters. A similar rectangle
has a width of 2 centimeters. What is the length of the second rectangle? (Sketch a picture)
Answers
Answer:
6
Step-by-step explanation:
I am unable to sketch a picture for you but I will do my best to help you understand. We know that our length of the first rectangle is 18 cm and the width is 6 cm. At the moment we don't need 18 so we'll put that to the side for now and focus on the width. We understand that in a second similar rectangle, the width is 2 centimeters. in order to find our scale, we must divide the larger width by the smaller width. This means we will divide 6cm by 2 cm. 6/2=3 This means that we also divide 18 by 3 since the similar rectangle is smaller and we are figuring out the missing side. After dividing 18 by 3 we should get an answer of 6. 18/3=6 Which means that our similar rectangle has a length of 6 cm and a width of 2 cm.
I also want to mention that similar rectangles are not the same rectangle however you can think of them as enlargerd/shrunk versions of the original rectangle. I hope this helps.

Please explain your answer, I will give brainliest, thank you!
Answers
Answer:
[tex] \displaystyle \text C)\csc( {225}^{ \circ } )= - \sqrt{2} [/tex]
Step-by-step explanation:
we want to figure out the exact value of the following:
[tex] \displaystyle \csc( {225}^{ \circ} ) [/tex]
recall that,
[tex] \displaystyle \csc( \theta ) = \frac{1}{ \sin( \theta)} [/tex]
we are given [tex]\theta=225°[/tex]
substitute:
[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{1}{ \sin( {225}^{ \circ} )} [/tex]
225° belongs to Q:III which we can clearly acquire from unit circle so,
[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{1}{ \dfrac{ - \sqrt{2} }{2} } [/tex]
By simplifying complex fraction we get:
[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{2}{ - \sqrt{ 2} } [/tex]
notice that, what we acquired isn't in the option so multiply it by √2/√2
[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{2}{ - \sqrt{ 2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } [/tex]
simplify multiplication:
[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{2 \sqrt{2} }{ - \sqrt{ 4} } [/tex]
simplify square:
[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{2 \sqrt{2} }{ - 2} [/tex]
reduce fraction:
[tex] \displaystyle \csc( {225}^{ \circ } )= - \sqrt{2} [/tex]
hence,
our answer is C

There is a triangle with sides measuring 30in, 30in and 25in. Is this a right triangle? Why or why not?
Answers
Answer:
No. In order to be a right triangle, the lengths of the 2 smaller sides must equal the length of the longest side.
In other words, these 3 sides must work with the Pythagorean theorem.
A^2 + B^2 = C^2
25^2 + 30^2 is NOT 30^2
This is a triangle, just not a right triangle.
Find the expected value of the winnings from a game that has the following payout probability distribution. Round to the nearest hundreath.
Answers
Step-by-step explanation:
Here, we want to calculate the expected value
What we have to do here is to multiply the probability by the payout value; after which we add all values
Thus, we have the payout value as;
1(0.12) + 4(0.2) +6(0.38) + 8(0.2) + 10(0.1)
= 0.12 + 0.8 + 2.28 + 1.6 + 1
The expected value of the winnings from a game will be [tex]2.96[/tex] .
What is Probability ?Probability is the ratio of the number of possible outcomes to the total number of outcomes.
we have,
Payout [tex](\$) = 0,\ \ \ 1,\ \ \ 2,\ \ \ 5,\ \ \ 10[/tex]
Probability [tex]=0.12,0.2,0.38,0.2,0.1[/tex]
So,
To find the expected value,
Now,
Multiply payout values with its probability and sum these values,
i.e.
Expected value [tex]= (0*0.12)+(1*0.2)+(2*0.38)+(5*0.2)+(10*0.1)[/tex]
[tex]=0+0.2+0.76+1+1[/tex]
Expected value [tex]=2.96[/tex]
Hence, we can say that the expected value of the winnings from a game will be [tex]2.96[/tex] .
