Answer:

The number is 4

Step-by-step explanation:

Let the number be  n

Twice the number : 2*n = 2n

Half the number : 1/2 n

[tex]2n+ \frac{n}{2}=10\\\\\frac{2n*2}{2}+\frac{n}{2}=10\\\\\frac{4n}{2}+\frac{n}{2}=10\\\\\frac{5n}{2}=10\\\\5n=10*2\\\\5n=20\\\\n=\frac{20}{5}\\\\[/tex]

Answer:

104

Step-by-step explanation:

f(x) = x^2 + 4

g(x) = 7x + 13.

Find g(f(3))

Find f(3) = 3^2+4 = 9+4 = 13

Then find g(13) = 7*13 + 13 = 91+13 = 104

Answer:

91x+169

g(f(3))

(7x+13)(3^2+4)

(7x+13)(9+4)

(7x+13)(13)

therefore..91x+169

Answer:

B. No solutions

Step-by-step explanation:

y= -3x + 9

3y = -9x + 9

Rewrite the first equation below. Then, divide both sides of the second equation by 3 and write it below the first equation.

y = -3x + 9

y = -3x + 3

Now look at the two equations. They are both written in the slope-intercept form, y = mx + b, where m = slope, and b = y-intercept. They have the same slope (m = -3) and different y-intercepts (9 and 3), so they are equations of two different lines, but since the slopes are the same, the lines are parallel. Since the lines never intersect, there is no solution.

Answer: No solutions

Answer:

740

Step-by-step explanation:

The n th term of an arithmetic series is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₃ = 7 and a₇ = (3 × 7) + 2 = 21 + 2 = 23 , then

a₁ + 2d = 7 → (1)

a₁ + 6d = 23 → (2)

Subtract (1) from (2) term by term

4d = 16 ( divide both sides by 4 )

d = 4

Substitute d = 4 into (1)

a₁ + 2(4) = 7

a₁ + 8 = 7 ( subtract 8 from both sides )

a₁ = - 1

The sum to n terms of an arithmetic series is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ] , thus

[tex]S_{20}[/tex] = [tex]\frac{20}{2}[/tex] [ (2 × - 1) + (19 × 4) ]

Answer:

The number of coupons Querida gave away in Sunday is proportional to the number of hours she worked that day.

Step-by-step explanation:

It is provided that on Sunday Querida gave away about 52 coupons an hour.

Compute the number of coupons given away for different hours as follows:

    Number of hours :    1         2          3          4

Number of Coupons :   52      104      156      208

Compute the number of coupons given away per hour provided that Querida worked 2 hours, 3 hours and 4 hours on Sunday as follows:

[tex]\text{Number of coupons given away per hour}=\frac{104}{2}=52\ \text{coupon/hour}[/tex]

[tex]\text{Number of coupons given away per hour}=\frac{156}{3}=52\ \text{coupon/hour}[/tex]

[tex]\text{Number of coupons given away per hour}=\frac{208}{4}=52\ \text{coupon/hour}[/tex]

Thus, the number of coupons Querida gave away in Sunday is proportional to the number of hours she worked that day.

Answer:

the answer is 65

Step-by-step explanation:

13x5=65

12 feet is the distance along the ground from the truck to the end of the ramp.

What is Pythagorean Theorem?

For a right-angled triangle

(base)²+(height)²=(hypotenuse)².

The ramp makes a right-angled triangle with the truck and the ground refer to the supported diagram.

Let x be the distance along the ground from the truck to the end of the ramp. Then

x²+5²=13²

⇒x²=13²-5²

⇒x²=169-25=144=12²

Hence, 12 feet is the distance along the ground from the truck to the end of the ramp.

Answer:

x-coordinates of point B = 3

Step-by-step explanation:

If the extreme ends of a segment are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], coordinates of the midpoint of the given segment will be = [tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Coordinates of the extreme ends of segment AC are A(-2, -3) and C(8, -3).

Since B is a point that bisects the segment AC, coordinates of point B will be,

= [tex](\frac{-2+8}{2},\frac{-3-3}{2})[/tex]

= (3, -3)

Therefore, x-coordinates of the point B will be = 3

Answer:

n=6

Step-by-step explanation:

6 ( n + 5 ) = 66

Divide each side by 6

6/6 ( n + 5 ) = 66/6

n+5 = 11

Subtract 5 from each side

n+5-5 = 11-5

n = 6

Answer:

n=6

Step-by-step explanation:

We are given the equation

6(n+5)=66

We must solve for the variable, n. Therefore, we have to isolate n on one side of the equation.

6 is being multiplied by (n+5). The inverse of multiplication is division. Divide both sides of the equation by 6.

6(n+5)/6=66/6

(n+5) = 66/6

n+5 = 11

5 is being added to n. The inverse of addition is subtraction. Subtract 5 from both sides of the equation.

n+5-5=11-5

n=11-5

n=6

Let's check our solution. Plug 6 in for n and solve.

6(n+5)=66

6(6+5)=66

6(11)=66

66=66

The statement above is true, so we know our solution is correct.

The solution to the equation 6(n+5)=66 is n=6

⇒[tex]\sf{ \frac{2(x - 3)(x + 3)(x + 2) + (x - 2)(x + 2)(x + 3) - 2(x - 2)(x - 3)(x + 3) - (x - 2)(x + 2)(x - 3)}{(x - 2)(x - 3)(x + 2)(x + 3)}} [/tex]

Use the formula : a² - b² = ( a + b ) ( a - b )

⇒[tex] \sf{ \frac{2( {x}^{2} - 9)(x + 2) + ( {x}^{2} - 4)(x + 3) - (2x - 4)( {x}^{2} - 9) - ( {x}^{2} - 4)(x - 3) }{( {x}^{2} - 4)( {x}^{2} - 9)}} [/tex]

Distribute 2 through the parentheses

Multiply the algebraic expressions

Since two opposites add up to zero, it would be better to remove them from the expression

The correct value is 720 ft of fencing.

Answer:

Max Area = 64800 sq.ft

Step-by-step explanation:

A square will always give us the maximum area.

Thus, one side would be;

720/4 = 180 feet

So, we want a square 180 ft by 180 ft

however, from the question, we are to use the creek as one side. So, we'll take the 180 ft that we don't need because of the creek and then add it to the opposite side to get 180 + 180 = 360 ft.

Thus,we now have a rectangle with dimensions: 180 ft by 360 ft

Area is given by;

area = length × width

Maximum Area = 180 × 360

Max Area = 64800 sq.ft

the square of 12 =12×12 =144

and the square root of 196324 = ✓196324

= 443.084642

When you create the number line, put 0 in the middle. Basically you put all the numbers you got from least to greatest on the number.

Since -3/2 is less than 0, it will go to the left of 0.

Since 3/2 and 5/2 are greater than 0, it will go to the right of 0.

Remember to use sub points of 1.

Best of Luck!
