Please help with this question​

consider first number is = x

formula,

(n / 2)(first number + last number) = sum,

7/2(x+x+6)= 945

2x+6= 945×2/7

2x+6 = 270

2x= 270-6

x=264/2= 132

Answer the smallest number is 132.

Answer:

64ft

Step-by-step explanation:

The distance between the lions and the monkeys is; 64 ft

From the given diagram, we see two triangles;

Triangle one formed by Zebras, Monkeys, lions.

Triangle two formed by tigers, elephants, lions

Now, from the given triangles we can see that they are similar and using the given dimensions, we can use proportion to find distance between the lions and the monkeys as;

52/78 = x/96

where x is the unknown distance we are looking for

We cross multiply to get;

4992 = 78x

Divide both sides by 78 to get;

x = 64 ft

Answer: y + 7 = 3/4(x - 0)

Step-by-step explanation:

This is point slope form: y - y1 = m(x - x1)

Plug in a coordinate for y1 and x1, but leave y and x alone. M is the slope.

So, plug everything in (for this specific problem, don't simplify after plugging the values in)

y - - 7 = 3/4(x - 0)

y + 7 = 3/4(x - 0)

Step-by-step explanation:

Arithmetic

To round, go to the length behind it.

2,413

If it is four or under, you keep the four and, you must turn everything to the left side to zero.

If it is five and up, turn the number into 3000.

Note: This cannot be rounded to 2,500 and 2,400 due to the question being asked.

Meaning, the equation formed is:

5x2,000=10,000

Answer: 10,000

Step-by-step explanation:

the equation is 5 x 2000=10,000

because 1 - 4 let it stay and 5-9 higher up the grade so is was a 2 but you don’t look at the 2 it depends on the number that’s next to it which is 4 and that Means it stays and everything turns into a zero except the two remains it means 5×2000 = 10,000

Number of sides , n

[tex]n = 10[/tex]

[tex]Interior \ angle= \frac{(n-2) \times 180}{n}[/tex]

[tex](5x -61) = \frac{(10-2) \times 180}{10}\\\\(5x - 61) = \frac{8 \times 180}{10}\\\\5x -61 = 144\\5x = 144 + 61\\x = 41[/tex]

Interior angle = 5x - 61 = (5 x 41) - 61 = 144

Answer: Choice B)

-5x^3 + 9x^2 + 2x

=================================================

Explanation:

Standard form is where the largest exponent term goes first, then the next largest, and so on. The exponents are decreasing when moving from left to right.

So that's why -5x^3+9x^2+2x is in standard form. Think of the 2x at the end as 2x^1. That might help show the exponents are decreasing (3,2,1).

The largest exponent is the degree, meaning that we have a third degree polynomial (aka cubic polynomial).

The first term -5x^3 is considered the leading term and -5 is the leading coefficient.

1. Get rid of the tax by subtracting 2.70 from the total.  

2. Next, divide the total by 3 to find the price of each CD.

Answer:

x = price of balcony tickets = $7

y = price of orchestra tickets = $21

Step-by-step explanation:

Let

x = price of balcony tickets

y = price of orchestra tickets

y = 3x (1)

148y + 76x = 3,640 (2)

Substitute y = 3x into (2)

148y + 76x = 3,640 (2)

148(3x) + 76x = 3,640

444x + 76x = 3,640

520x = 3,640

x = 3,640/520

x = 7

Substitute x = 7 into (1)

y = 3x (1)

y = 3(7)

y = 21

x = price of balcony tickets = $7

y = price of orchestra tickets = $21

1 acre of land requires [tex]5\frac{1}{2}[/tex] bags

convert mixed numeral to fraction

[tex]\Rightarrow 5\dfrac{1}{2}=\dfrac{11}{2}[/tex]

[tex]\therefore 1\ \text{acre}\equiv\dfrac{11}{2}\ \text{bags}\\\\\Rightarrow \dfrac{3}{4}\ \text{acre}\equiv \dfrac{11}{2}\times \dfrac{3}{4}=\dfrac{33}{8}\ \text{bags}[/tex]

Answer:

V = 2304π units³

Step-by-step explanation:

The volume (V) of a sphere is calculated as

V = [tex]\frac{4}{3}[/tex]πr³ ( where r is the radius ) , then

V = [tex]\frac{4}{3}[/tex]π × 12³

   = [tex]\frac{4}{3}[/tex] π × 1728

   = 4π × 576

   = 2304π units³

Step-by-step explanation:

For the rectangular prism in the middle:

[tex]24*30=720*2=1140[/tex]

[tex]10*30=300*2=600[/tex]

[tex]1140+600=1740[/tex]

For the left triangular prism:

[tex]10*24=240[/tex]

[tex]26*30=780[/tex]

[tex]24*30=720[/tex]

[tex]10*30=300[/tex]

[tex]240+780+720+300=2040[/tex]

For the other right triangular prism, it's the same.

Let's add now to find the surface for the whole ramp.

[tex]1740+2040+2040=5820[/tex]
