Answer:

7/75

Explantion:

To get the answer as a fraction you must first have a common denominator

so . .

105 is a common denominator

So . .

Multiply 5/7 by 15

Multiply 1/15 7

Divide = 7/75

Answer:

36

Step-by-step explanation:

Area of a triangle = A = hb x b

A = 12 x 7 = 84                    2

84/2 = 42

rectangle area = l x w

2 x 3 = 6

42 - 6

36

Step-by-step explanation:

x + 5 = 3x -12 + 5

x + 5 = 3x - 7

Subtract 5 from both sides....

x + 5-5 = 3x -7 - 5

x = 3x - 12

Change the sign ...

12 = 3x - x

12 = 2x

12/2 = x

x = 6

hence 6 is the answer.......

[tex]\large\textsf{\textbf{Answer\::}}[/tex]

x=6

[tex]\large\textsf{\textbf{Calculations\::}}[/tex]

First , use the Distributive Property :

x+5=3(x-4)+5

x+5=3x-12+5

x+5=3x-7

subtract 3x on both sides :

x-3x+5=-7

-2x+5=-7

Subtract 5 on both sides :

-2x=-7-5

-2x=-12

divide by -2 on both sides :

x=6

We've found the value of x : x = 6 .

The square pyramid with a base with edges of 6 inches and slant height of 4 inches have a surface area of 84 in².

The net of the square pyramid have a base of 6 inches and the height of each triangle is 4 inches.

An equation is an expression that shows the relationship between two or more numbers and variables.

The square pyramid with a base with edges of 6 inches and slant height of 4 inches. Hence:

Surface area = (6 * 6) + 2(6 * 4) = 84 in²

Note that when two shapes are similar, it is said that their corresponding angles are often same.  The angles are also known to be the same because the shape is still of the same shape and as such one can be able to tell from the way or order of the similarity based on the way that the angles match up and also in the scenario above.

Answer:

  g(x) = -x +1

Step-by-step explanation:

The transformation that reflects f(x) across the y-axis is replacement of x with -x.

__

For f(x) = x +1, replacement of x with -x will perform the desired transformation:

  g(x) = f(-x) = (-x) +1

  g(x) = -x +1

Reflection across y axis rule

so x turns negative

Solving

Add 3 to each side.

Subtract 5x from each side.

8.1. If x is the distance from P to the flagpole and h is the height of the flagpole, then

tan(53°) = h/x

tan(28°) = h/(x + 20)

Solve for the first equation for h in terms of x :

h = x tan(53°)

Substitute this into the second equation and solve for x :

tan(28°) = x tan(53°) / (x + 20)

(x + 20) tan(28°) = x tan(53°)

x tan(28°) + 20 tan(28°) = x tan(53°)

x (tan(28°) - tan(53°)) = -20 tan(28°)

x = 20 tan(28°) / (tan(53°) - tan(28°))

x ≈ 13.4 m

8.2. By the law of cosines,

BD² = 7² + 11² - 2 • 7 • 11 cos(110°)

⇒   BD = √(170 - 154 cos(110°))

⇒   BD ≈ 14.9 cm

and

BC² = BD² + 16² - 2 • BD • 16 cos(40°)

⇒   BC = √(426 - 154 cos(110°) - 32 cos(40°) √(170 - 154 cos(110°)))

⇒   BC ≈ 10.6 cm

Now use Heron's formula. If S is the semiperimeter of ∆ABD and S' is the semiperimeter of ∆BCD, i.e.

S = (AB + BD + AD)/2 ≈ 16.5 cm

S' = (BC + CD + BD)/2 ≈ 20.7 cm

then

area ∆ABD = √(S (S - AB) (S - BD) (S - AD)) ≈ 36.2 cm²

and

area ∆BCD = √(S' (S' - BC) (S' - CD) (S' - BD)) ≈ 76.7 cm²

so that the total area of ABCD is approximately 112.9 cm².

First we need to determine what cos is asking for.  Using Soh Cah Toa we can tell that we are using adjacent (a) and hypotenuse (h).  The leg that is adjacent to Q is equal to 10 while the hypotenuse is equal to 21.

[tex]cos(Q)=\frac{adjacent}{hypotenuse}[/tex]

[tex]cos(Q) = \frac{10}{21}[/tex]

After getting to this part, we have to take the inverse of cos in order to cancel the cos on the left and leave Q by itself.

[tex]cos^{-1}(cos(Q))=cos^{-1}(\frac{10}{21})[/tex]

[tex]Q = 61.56\ degrees[/tex]

In the end we are left with that our angle Q is equal to 61.56 degrees.

The standard deviation is a measure of a collection of values' variance or dispersion. The true mean bill for a customer at Burger Palace with 95% confidence is $13.38.

The standard deviation is a measure of a collection of values' variance or dispersion. A low standard deviation implies that the values are close to the set's mean, whereas a high standard deviation shows that the values are spread out over a larger range.

Given that the Sample mean ([tex]\overline x[/tex]) is $14.30, the Sample size(n) is 24 customers, the Standard deviation(σ) is 2.30, while for a 95% confidence interval the Z-score is 1.960. Therefore, the true mean can be written as,

[tex]Z = \dfrac{\overline x- \mu}{\frac{\sigma}{\sqrt n}}\\\\\\1.960 = \dfrac{14.30-\mu}{\frac{2.30}{\sqrt{24}}}\\\\\\1.960 = \dfrac{14.3-\mu}{0.47}[/tex]

Answer:

9

Step-by-step explanation:

x is 9 assuming they are identical triangles.

Total amount in the reservoir = amount of water in the 10th month - (rate of decline x number of months from the 10th month)

Rate of decline = (300  262) / (18 - 10) = 4.75

y = 300 million = 4.75x

Where x is the time of the month.

Total amount in the reservoir = amount of water in the 10th month - (rate of decline x number of months from the 10th month)

300 million - (4.75 x 4) = 281 million

0 = 300 - (4.75x)

x = 300 / 4.75

For 12 objects, we can substitute x = 12

⇒ t = (3/1000) (12)² + (1/1000) 12

⇒ t = (12/1000) (3 × 12 + 1)

⇒ t = (12×37/1000)

⇒ t = 444/1000
