Answer:

1.09 x 10^2

Step-by-step explanation:

1.39 x 10^6 / 1.27 x 10^4 = 1.09448818898

1.09448818898 is rounded 1.09

10^6-4 = 10^2

So, 1.09 x 10^2

The sun is approximately 109.29 times larger in diameter than the Earth.

To determine how many times larger in diameter the sun is compared to the Earth, we divide the diameter of the sun by the diameter of the Earth.

The diameter of the sun is 1.39 × 106 kilometers, while the diameter of the Earth is 1.27 × 104 kilometers.

Dividing the diameter of the sun by the diameter of the Earth, we get (1.39 × 106) / (1.27 × 104) = 109.29.

Therefore, the sun is approximately 109.29 times larger in diameter than the Earth.

Step-by-step explanation:

Final answer:

To find percentages of numbers, convert the percent to a decimal and then multiply. To find the unknown quantity in an equation involving percentages, divide the given number by the percent expressed as a decimal.

Explanation:

To find 66 2/3 percent of 87, first convert the percent to a decimal by dividing it by 100: 66 2/3 ÷ 100 = 0.6667. Then multiply the decimal by 87: 0.6667 x 87 = 58.33. So, 66 2/3 percent of 87 is approximately 58.33.

To find 1 percent of 3,620, divide 3,620 by 100: 3,620 ÷ 100 = 36.2. So, 1 percent of 3,620 is 36.2.

To find x in the equation 62 1/2 percent of x is 5, first convert the percent to a decimal: 62 1/2 ÷ 100 = 0.625. Then divide 5 by the decimal: 5 ÷ 0.625 = 8. So, x is 8.

To find k in the equation 300 percent of k is 42, first divide 42 by 300: 42 ÷ 300 = 0.14. So, k is 0.14.

The cost of bench is 325.

Step-by-step explanation:

Given,

Combined cost of table and bench = 725

Let,

x be the cost of garden table

y be the cost of bench

According to given statement;

x+y=725         Eqn 1

x = y+75         Eqn 2

Putting value of x from Eqn 2 in Eqn 1

[tex](y+75)+y=725\\y+75+y=725\\2y=725-75\\2y=650[/tex]

Dividing both sides by 2

[tex]\frac{2y}{2}=\frac{650}{2}\\y=325[/tex]

The cost of bench is 325.

The equation of the line is y = [tex]\frac{5}{4}[/tex] x +  [tex]\frac{9}{2}[/tex]

Step-by-step explanation:

The form of the linear equation is y = mx + b, where

∵ A line passes through points ( [tex]\frac{2}{5}[/tex] , 5) and ( [tex]-\frac{2}{5}[/tex] , 4)

∴ [tex]x_{1}[/tex] =  [tex]\frac{2}{5}[/tex]  and [tex]x_{2}[/tex]  =  [tex]-\frac{2}{5}[/tex]

∴ [tex]y_{1}[/tex] = 5  and  [tex]y_{2}[/tex] = 4

- Substitute them in the rule of the slope to find m

∵ [tex]m=\frac{4-5}{-\frac{2}{5}-\frac{2}{5} }[/tex]

∴ [tex]m=\frac{-1}{-\frac{4}{5}}=\frac{5}{4}[/tex]

- Substitute it in the form of the equation

∴ y = [tex]\frac{5}{4}[/tex] x + b

- To find b substitute x and y in the equation by the coordinates

   of any point on the line

∵ Point ( [tex]\frac{2}{5}[/tex] , 5) lies on the line

∴ x = [tex]\frac{2}{5}[/tex]  and y = 5

∴ 5 = [tex]\frac{5}{4}[/tex] (  [tex]\frac{2}{5}[/tex] ) + b

∴ 5 = [tex]\frac{1}{2}[/tex] + b

- Subtract  [tex]\frac{1}{2}[/tex]  from both sides

∴ [tex]\frac{9}{2}[/tex]  = b

∴ y = [tex]\frac{5}{4}[/tex] x +  [tex]\frac{9}{2}[/tex]

The equation of the line is y = [tex]\frac{5}{4}[/tex] x +  [tex]\frac{9}{2}[/tex]

Answer:

J=67

T=67

G=180-67-67

St=5

HJ=3.7

Step-by-step explanation:

The two triangles are equal.

Since the triangle at isosceles, two sides/angles are equal.

The measure of the angles and the sides are:

m∠J = 67

m∠T = 67

m∠G =46

ST = 5 cm

HJ = 3.7 cm

We have,

ΔGHJ ≡ Δ STU

This means,

The corresponding sides and angles are the same.

Now,

GH = ST = GJ = SU = 5cm

And,

HJ = TU = 3.7 cm

Now,

The sum of the angles in the triangle = 180

In GHJ,

m∠J = 67

This is because angles opposite to the equal sides are the same.

Now,

∠G + ∠H + ∠J = 180

∠G + 67 + 67 = 180

∠G = 180 - 134

m∠G = 46

And,

m∠T = 67

Since ΔGHJ ≡ Δ STU.

Thus,

The measure of the angles and the sides are:

m∠J = 67

m∠T = 67

m∠G =46

ST = 5 cm

HJ = 3.7 cm

Answer:

The co-ordinates which give the minimum value for the quadratic function are (-7, -47)

Step-by-step explanation:

i) the quadratic function f(x) = [tex]x^{2}[/tex]  + 14x + 2

                                             = [tex]x^{2}[/tex]  +   14x + 49 - 49 + 2

                                             =  [tex](x + 7)^{2}[/tex]   - 49 + 2

                                            = [tex](x+7)^{2}[/tex]  - 47

ii) The minimum value of the result of the quadratic equation in i) will be achieved when [tex](x + 7)^{2}[/tex] is zero as any square value is always positive and thus the minimum value of a square is always zero.

iii) [tex](x + 7)^{2}[/tex]  is zero when x  = -7 and when x = -7  then y = f(x) = -47

iv) The co-ordinates which give the minimum value for the quadratic function are (-7, -47)

The triangle given has base 60 and height 45

The scale says "1 unit:5 meters" which means that each unit on the grid is 5 meters. We can divide each dimension of the given triangle by 5 so we figure out how many units we'll need for each dimension of the new smaller triangle (that is similar to the original)

60/5 = 12

45/5 = 9

The smaller triangle must have a base of 12 and a height of 9

See the diagram below.

The area of this new triangle is (base*height)/2 = (12*9)/2 = 108/2 = 54 square units.

Answer:

(x - 6)² = - (y - 4)

The vertex of the parabola will be (6,4).

The x-intercepts are at (8,0) and (4,0).

Step-by-step explanation:

Given the equation of parabola is g(x) = y = - x² + 12x - 32 .......... (1)

Now, converting the equation to vertex form.

Here, y = - x² + 12x - 32

⇒ y = - (x² - 12x + 36) + 4

⇒ y - 4 = - (x - 6)²

⇒ (x - 6)² = - (y - 4) ........... (2) (Answer)

Now, the vertex of the parabola will be (6,4) and it opens down. (Answer)

Let the x-intercept of the parabola is at (h,0).

Hence, from equation (2) we get,

(h - 6)² = - (0 - 4) = 4

⇒ h - 6 = ± 2

⇒ h = 8 or h = 4

Therefore, the x-intercepts are at (8,0) and (4,0). (Answer)

Step-by-step explanation:

If two or more points have the same domain or x value, then it is not a function because points cannot have identical x values, only y values.

With this in mind, C is not a function because there are two 4s in the domain.

So looking at this our answer would be C because when you are trying to find if it is not a function you have to look for repeated X values or domains if there I s a problem with a repeated X value that would not be a function but if the Y values were to repeated that doesn’t really matter so yeah.

Answer:

X= -9/10

y= -2 3/5

Step-by-step explanation:

Multiply equation one by 4 and equation two by 3 to eliminate X

it becomes

-12x + 8y =-12

12x - 3y = -1

add equation one and two,

you'll be left with 5y= -13

divide both sides by 5

y = -13/5 improper fraction

= -2 3/5

Now substitut y = -2 3/5 into any of the original equations to get x.

using equation two, we have

4x -(-2 3/5) = -1

4x + 2 3/5 = -1

4x = -1 - 2 3/5

the LCM of 5 is 5 , so

4x = -5-13/5

4x = -18/5

crossmultiply

4x x 5 = -18

20x = -18

divide both sides by 20

we have x = -18/20, when you cancel further , you have x = -9/10
