Answer:

150 miles

Step-by-step explanation:

15÷100×1000=150

Step-by-step explanation:

From graph of g(x), it is observed that y - intercept is 6.

Therefore,

[tex]6 = 2(3)^{0} + k[/tex]

[tex]k \: = 4[/tex]

The value of k is equal to 4

Function, in mathematics, is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given here the functions  f(x)=2(3)ˣ and g(x)=f(x)+k when x=0 we get

f(0)=2  and from the graph we can clearly observe that g(0)=6

Thus putiing in the values we get k=4

Hence, The value of k is equal to 4

Answer:

[tex]x=3/2=1.5[/tex]

Step-by-step explanation:

So we have the equation:

[tex]2x-2=4x-5[/tex]

And we want to solve for x. To do this, we need to first isolate the x-variable. So, start by adding 2 to both sides:

[tex](2x-2)+2=(4x-5)+2[/tex]

The 2s on the left cancel:

[tex]2x=4x-3[/tex]

Now, subtract 4x from both sides:

[tex](2x)-4x=(4x-3)-4x[/tex]

The 4xson the right cancel:

[tex]-2x=-3[/tex]

Now, divide both sides by -2.

[tex]\frac{(-2x)}{-2}=\frac{-3}{-2}[/tex]

The negatives cancel. The 2s on the left cancel. Therefore:

[tex]x=3/2=1.5[/tex]

Answer:

54

Step-by-step explanation:

since x= 0.6 and y=5 you replace them in 2(xy)^3

then it would be 2((0.6)(5))^3

first multiply the numbers inside 0.6 times 5 =3

second multiply 3 three times =27

lastly multiply 27 times 2 to get finally 54

Answer:

2x-2= -21

Step-by-step explanation:

Answer:

-9.5

Step-by-step explanation:

We can create an equation to represent this, where [tex]n[/tex] is the missing value.

[tex]2n - 2 = -21[/tex]

Now we can solve for [tex]n[/tex] by isolating it on one side of the equation.

Add 2 to both sides:

[tex]2n - 2 + 2 = -21+2\\\\2n = -19[/tex]

Divide both sides by 2:

[tex]2n\div2 = -19\div2\\\\n = -9.5[/tex]

Divide each side by 12

12m/12 = 14.4/12

m = 1.2

m = 1.2  is the answer

because..

12m = 14.4

Divide each side by 12

12m/12 = 14.4/12

m = 1.2

Answer:

[tex]LO = OT = 8cm[/tex]

Step-by-step explanation:

Given

LT = 16cm

Required

Determine LO and OT

First, we have:

[tex]LO + OT = LT[/tex]

From the question, we understand that O is the middle of LT

This implies that LO = OT

Substitute OT for LO in the above formula

[tex]OT + OT = LT[/tex]

[tex]2OT = LT[/tex]

Divide both sides by 2

[tex]OT = \frac{1}{2}LT[/tex]

Substitute 16cm for LT

[tex]OT = \frac{1}{2} * 16cm[/tex]

[tex]OT = 8cm[/tex]

Recall that LO = OT

So;

[tex]LO = OT = 8cm[/tex]

Answer:

c = 7

Step-by-step explanation:

Solve for 'c'

-7c - 5 = -9c + 9

-5 -9 = -9c + 7c

-14 = -2c

c = 7

Therefore 'c' equals 7

Answer:

c=7

Step-by-step explanation:

-7c-5=-9c+9

Add 9c to each side

-7c+9c-5=-9c+9c+9

2c -5=9

Add 5 to each side

2c-5+5 = 9+5

2c = 14

Divide each side by 2

2c/2 = 14/2

c=7

Step-by-step explanation:

A can't be correct because the length of a segment is always positive. B is correct because we have to take the absolute value of the distance between endpoints to find the length of the segment. C is not correct because AC is obviously longer than BC so how would AB + AC = BC? D is correct because it models the Parts Whole Postulate.

Number line are used to represent numbers on a line at regular intervals. The possible coordinates of G is either 10 or -14.

Given that:

[tex]G = 2[/tex]

[tex]EG = 12[/tex]

The equation that calculates EG is:

[tex]EG = |E - G|[/tex]

So, we have:

[tex]12 = |2 - G|[/tex]

Remove absolute brackets

[tex]2 - G = \± 12[/tex]

Add 2 to both sides

[tex]-G =2 \± 12[/tex]

Rewrite as:

[tex]G =-2 \± 12[/tex]

Split

[tex]G =- 2 - 12[/tex] or [tex]G = -2 + 12[/tex]

[tex]G = -14[/tex] or [tex]G = 10[/tex]

Answer:

2:45

Step-by-step explanation:

The original price is 100%, a 15% discount means the shoes are now ( 100-15 = 85) 85% of the original price,.

Multiply the original price by 85%

60 x 0.85 = 51

The price is $51

Answer:

$51

Step-by-step explanation:

15% discount means that the new price is 85% of the original one. Therefore we just need to multiply 60 by 0.85 to find 85% of the number.

60x0.85=$51

The new price would be $51.

Similarly you could also have divided 60 by 100 to find one percent of it (60/100=0.6) and then multiplied it by 85 to find 85%. (0.6x85=51)

x = 30    Quadrilateral

x = 20    Triangle

Step-by-step explanation:

Quadrilateral

A quadrilateral has a sum of 360 degrees for its interior angles.

So

x + 2x + 4x + 5x = 360       Find the sum of the 4 angles

12x = 360                           Divide by 12

12x = 360/12                      

x = 30                                 Answer

Triangle

A triangle has an interior angle sum of 180 degrees.

2x + 5x  + (x + 20) = 180         Remove the brackets

2x + 5x  + x + 20 = 180           Add the angles

8x + 20 = 180                           /subtract 20 from both sides

8x = 180 - 20

8x = 160                                 Divide by 8

x = 160/8

x = 20    

Answer:

s = 5.48 in

Step-by-step explanation:

Area of square = s²

30 in² = s²

s = √30

s = 5.48 in

Answer:

Approximately 5.48 inches.

Step-by-step explanation:

Area of a square formula: Area = length^2

Area here = 30 in^2

30 = length^2

Take square root of both sides to get rid of the square.

[tex]\sqrt{30\\}[/tex] = length

length = 5.47722558

The approximate side length of the frame is about 4.58 inches.

Answer: a) -27, b) 35, c) 14

Step-by-step explanation:

a) When a positive number is multiplied by a negative number, your answer is negative, and since we know that 9 × 3 = 27, and that this figure has to be negative (since 9 is negative), the answer is -27.

b) Multiplying two negative numbers gives a positive number, and since 7 × 5 = 35, the answer is positive 35 (as both 7 and 5 in the original question are negative).

c) Follows just like b.
