Answer:

[tex]7.96 *10^8kg[/tex]

Step-by-step explanation:

Given

[tex]Eiffel = 9.16 * 10^6\ kg[/tex]

[tex]Golden\ Gate =8.05 * 10^8kg[/tex]

Required

Determine the difference in mass

This is calculated by subtracting the mass of Eiffel tower from the mass of Golden gate bridge

[tex]Difference = Golden\ Gate - Eiffel[/tex]

[tex]Difference = 8.05 * 10^8 - 9.16 * 10^6[/tex]

Express [tex]10^8[/tex] as [tex]10^6 * 10^2[/tex]

[tex]Difference = 8.05 * 10^2*10^6 - 9.16 * 10^6[/tex]

Express [tex]10^2[/tex] as [tex]100[/tex]

[tex]Difference = 8.05 * 100*10^6 - 9.16 * 10^6[/tex]

[tex]Difference = 805 *10^6 - 9.16 * 10^6[/tex]

Factorize:

[tex]Difference = (805- 9.16) * 10^6[/tex]

[tex]Difference = 795.84 * 10^6[/tex]

Factorize the decimal number

[tex]Difference = 7.9584 *10^2 * 10^6[/tex]

[tex]Difference = 7.9584 *10^8[/tex]

Approximate:

[tex]Difference = 7.96 *10^8[/tex]

Answer:

1.

Step-by-step explanation:

sec 16° cosec 74° - cot 74° tan 16°​

= 1/ cos 16 * 1/ sin 74 - 1/tan 74 * tan16

= 1/ cos16 sin 74 -  cos74/ sin74 *  sin 16 / cos 16

Now cos 16 = sin 74  and sin 16 = cos 74  (supplementary angles) so:

= 1 / cos^2 16   - sin 16/cos 16 * sin 16 / cos 16

=( 1 - sin ^2 16 )/ cos^2 16

= cos^2 16 / cos^2 16

= 1.

Alternate interior angles measure same as per their property:

Answer:

y = -3

Step-by-step explanation:

Given the expression 7-(3.1-0.1у)=3-0.2у

We are to find the value of y as shown

7-(3.1-0.1у)=3-0.2у

Open the parenthesis

7-3.1+0.1y= 3-0.2y

3.9+0.1y = 3-0.2y

Collect like terms

0.1y+0.2y= 3-3.9

0.3y = -0.9

y = -0.9/0.3

y = -3

Hence the value of y is -3

Answer:

38 degrees, see below :)

Step-by-step explanation:

Hello! :)

So, we can use the Base Angles theorem to say the angle with 62 degrees is equal to angle 1.

Now we know angle 1 = 62 degrees.

Next, we can use the exterior angles theorem to say that angle 3 is the sum of the remote interior angles of the triangle so:

angle 3 = 62 + angle 1

= 62 + 62

= 124

Now we know angle 3 = 124 degrees

We can find angle 4 by subtracting 18 degrees and angle 3 from 180 degrees because we know that they all have to add up to 180 so:

angle 4 = 180 - (18 + 124)

= 180 - 142

= 38 degrees.

Answer:

Step-by-step explanation:

The graph for the given equations is plotted in graph below.

The given equation is y=3/2 x+1.

Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.

Graph the line using the slope and y-intercept, or two points.

Slope: 3/2

y-intercept: (0,1)

Plot (0, 1) and (2, 4)

Therefore, the graph for the given equations is plotted in graph below.

Answer:

h(x), g(x), f(x)

Step-by-step explanation:

The y-intercept of h(x) = -1        (0, -1)

The y-intercept of g(x) = 1          (0,1)

The y-intercept of f(x) = 2          (0, 2)

Answer:

There are five triangles in a heptagon. A heptagon is a seven-sided polygon.

Step-by-step explanation:

First difference,

[tex]\Delta_{1} = a_{2} - a_{1} = 3 - 1 = 2 = 1 + 1[/tex]

Second difference,

[tex]\Delta_{2} = a_{3} - a_{2} = 6 - 3 = 3 = 2 + 1[/tex]

Third difference,

[tex]\Delta_{3} = a_{4} - a_{3} = 10 - 6 = 4 = 3 + 1[/tex]

And so on.

Assuming the pattern holds on, we see that

i-th difference,

[tex]\Delta_{i} = a_{i + 1} - a_{i} = i + 1[/tex]

[tex]\implies a_{i + 1} = a_{i} + i + 1[/tex]

Then, nth term is,

[tex]\implies a_{n} = a_{n - 1} + n[/tex]

[tex]= a_{n - 2}+ (n + (n - 1))[/tex]

[tex]= a_{n - 3} + (n + (n - 1) +(n - 2))[/tex]

[tex]= a_{n - (n - 1)} + \sum \limits^{n - 2}_{k = 0}(n - k)[/tex]

[tex]= a_1 + \sum \limits^{n - 2}_{k = 0}n- \sum \limits^{n - 2}_{k = 0}k[/tex]

[tex]= a_1 +n(n -2 + 1 )- \frac{1}{2} (n - 2)(n - 1)[/tex]

[tex]= a_1 +n(n -1 )- \frac{1}{2} (n - 2)(n - 1)[/tex]

[tex]= a_1 +(n -1 )(n- \frac{1}{2} (n - 2))[/tex]

[tex]= a_1 + \frac{1}{2} (n -1 )(2n- n + 2)[/tex]

[tex]= a_1 + \frac{1}{2} (n -1 )(n + 2)[/tex]

[tex]\implies a_{n} = 1 + \frac{1}{2} (n -1 )(n + 2)[/tex]

Now, the 21st term in the sequence is,

[tex]\implies a_{21} = 1 + \frac{1}{2} (21 -1 )(21 + 2)[/tex]

[tex]= 1 + \frac{1}{2} \times 20 \times 23[/tex]

[tex]= 231[/tex]

Answer:

x³ + x²y - 2xy² - xy + y²

Step-by-step explanation:

Given

(x - y)(x² + 2xy - y)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x² + 2xy - y) - y(x² + 2xy - y) ← distribute both parenthesis

= x³ + 2x²y - xy - x²y - 2xy² + y² ← collect like terms

= x³ + x²y - 2xy² - xy + y²

Answer:

as below

Step-by-step explanation:

(x-y)([tex]x^{2}[/tex]+2xy-y)

[tex]x^{3}[/tex]+2[tex]x^{2}[/tex]y-xy-[tex]x^{2}[/tex]y-2x[tex]y^{2}[/tex]+[tex]y^{2}[/tex]

[tex]x^{3}[/tex]+[tex]x^{2}[/tex]y-xy-2x[tex]y^{2}[/tex]+[tex]y^{2}[/tex]

Answer:

1395.9375

Step-by-step explanation:

All you do is add 25%

Answer:

1395.9375

Step-by-step explanation:

Answer:

1) 4·(n + 9) = 4·n + 4·9; Distributive Property

2) (6·7)·m = 6·(7·n); Associative Property of Multiplication

3) b · 1 = b; Multiplicative Identity Property

4) a + (-a) = 0; Additive Inverse Property

Step-by-step explanation:

1) The given equation and the properties that justifies the equation are;

4·(n + 9) = 4·n + 4·9

The above equation can be written as follows;

4 × (n + 9) = 4 × n + 4 × 9

Therefore, the common factor, 4 is distributed across the to the two terms inside the parenthesis, which gives the property as distributive property

2) (6·7)·m = 6·(7·n)

The above equation gives the association of the product of the  first two terms on the left multiplied by the third term being equal to the product of the first term and the association of the product of the last two terms on the right of the term on the right hand side of the equation

Therefore, we have associative property of multiplication

3) b · 1 = b

The value of the product of any variable and 1 is the value of the variable

Therefore, we have the multiplicative identity property

4) a + (-a) = 0

The sum of a variable (or number) and the negative (or opposite) of the variable (or number) is 0

Therefore, we have the additive inverse property

Answer:

A) X<5

Step-by-step explanation:

The circle is open, and the line is pointing left meaning it is less than five.

Answer:

A. Genevieve

B. Sierra

Step-by-step explanation:

Genevieve uses 5 balloons per animal, but Sierra uses 6. We can find this by subtracting 360 from 440 (which gets us 80). To find the unit rate, we divide 20 into 80 (the amount of balloons used when she made 20 animals), and we get 4. So, Sierra uses 4 balloons per animal.

Since Genevieve uses more balloons per animal and started with less balloons than Sierra (she started with 425, versus Sierra, who started with 440), Sierra will have made more animals by the end of the day.

I hope this helps!
