Answer: [tex]Domain = \{t: t\geq 0\}=[0,\infty)[/tex] and [tex]Range = \{v: v\geq 550\}=[550,\infty)[/tex].

Step-by-step explanation:

It is given that, the value of this account, v, is given by the function

[tex]v=550+16.5t[/tex]

where, t is the number of years the money is in the bank.

We need to find the domain & range of this function.

Domain is the set of input values. Here, the domain is number of years which cannot be negative. So,

[tex]Domain = \{t: t\geq 0\}=[0,\infty)[/tex]

Range is the set of output values. Here, the range is amount after simple interest which cannot be less than the principal value.

[tex]Range = \{v: v\geq 550\}=[550,\infty)[/tex]

Answer:

Yes.

Step-by-step explanation:

A fraction is a part of a whole number, so yes a fraction is always less than a whole number, unless it's a mixed number. A mixed number is when there is a whole number before the fraction.

Plaz mark brainliest. I just need 2 more to raise my level.

Answer:

Yes unless the fraction is equal to a whole number or is an improper fraction

Step-by-step explanation:

A normal fraction like 2/4 is less than a whole number because a whole number is whole and a fraction is part of

Exceptions:

4/4 is a fraction but is also a whole number

any improper fraction ( a fraction not simplified)

5/4 it equals more than a whole number 1 1/4

So simplify the fraction and if it is equal to or more than a whole number you know, but if it is less than a whole number then you know it is less.

Hopefully this helped :)

Answer:

[tex]Equation = 225 + 50y[/tex]

Step-by-step explanation:

Given

Members = 75

Cost of Shirt = $3

Color = $50 on all shirts

Required

Determine an equation to represent the scenario

Represent the members with x

Such that:

[tex]x = 75[/tex]

First, we need to determine the total cost of ordering x shirts

A shirt costs $3;

So,

[tex]x\ shirts = 3 * x[/tex]

[tex]x\ shirts = 3 x[/tex]

Next, we determine the total cost of colors

Represent each color with y

[tex]1\ color = \$50[/tex]

[tex]y\ color = \$50 * y[/tex]

[tex]y\ color = 50 y[/tex]

The required equation is calculated as thus;

[tex]Equation = x\ shirts + y\ color[/tex]

[tex]Equation = 3x + 50y[/tex]

Substitute 75 for x

[tex]Equation = 3 * 75 + 50y[/tex]

[tex]Equation = 225 + 50y[/tex]

Answer:

50 + 3(B) + 50 + 3(R) + 50 + 3(Y) would be the equation.

Answer:

27 =x

Step-by-step explanation:

The two angles are vertical angles and vertical angles are equal

4x+7 = 5(x-4)

Distribute

4x+7 = 5x-20

Subtract 4x from each side

4x+7-4x = 5x-4x-20

7 = x-20

Add 20 to each side

7+20 = x-20+20

27 =x

Answer:

x = 27

Step-by-step explanation:

Since they are corresponding they have to be equal.

4x+7 = 5(x-4)

4x+7 = 5x-20 distribute the 5

7 = 5x-4x-20 bring the 4x over

7 = x-20 simplify the x

7+20= x bring the twenty over

27=x

☆ First we need to Distribute:

⇒ (2)(3m)+(2)(4)+(3)(m)+(3)(−5)

⇒ 6m+8+3m+−15

☆ Now Combine Like Terms:

⇒6m+8+3m+−15

Answer:

[tex]m^2-9[/tex]

Step-by-step explanation:

Simplify [tex]m^2-3m+3m-9[/tex]

add -3m and 3m

[tex]m^2+0-9[/tex]

add [tex]m^2[/tex] and 0

[tex]m^2-9[/tex]

First known equation is:

2L + 2W = 46

Second equation is:

L = W +7

Put the variable L of the second equation in the first equation.

2(W+7) + 2W = 46

2W +14 +2W = 46

4W = 32

W=8

Then resolve L using any of the above initial equations

L = 8 + 7 = 15

Verify: 2L +2W = 46

2(15) + 2(8) = 30 + 16 = 46 = perimeter

Step-by-step explanation:

Let the length = 7x

Let the breadth = x

As we know that

perimeter of rectangle =2(l+b)

Also perimeter here = 78 inches

Acc. to question

2(l+b) = 78 inches

[tex]2(7x + x) = 78[/tex]

[tex]16x = 78[/tex]

[tex]x = \frac{78}{16} [/tex]

[tex]x = 4.8[/tex]

so bredth = 4.8 approx

length = 7*4.5 =31.5 approx

Answer:

B=2

Step-by-step explanation:

[tex](\frac{8+x_1}{2} )(\frac{0+y_1}{2})[/tex]

[tex](\frac{8+x_1}{2} )=2[/tex]  multiply 2 by 2=4 then write [tex]8+x_1=4[/tex] subtract  8 from both sides 4-8= -4

[tex](\frac{0+y_1}{2} )=1[/tex] multiply 2 by 1=2 then write [tex]0+y_1=2[/tex] subtract 0 from both sides

2-0=2

To check [tex]MP= (\frac{x_1+x_2}{2} )(\frac{y_1+y_2}{2} )\\[/tex]

[tex]MP= (\frac{-4+8}{2} )(\frac{2+0}{2} )[/tex] -4+8=4 2+0=2

[tex]MP= (\frac{4}{2} )(\frac{2}{2} )[/tex] 4/2=2 and 2/2=1 MP=(2,1)

Answer:

6

Step-by-step explanation:

2/3x=4

then 4/ 2/3 (you can just input this in a calculator)

it equals 6!

Answer:

x=6

Step-by-step explanation:

2/3x + 3 = 7

subtract 3 from both sides to get

2/3x = 4

divide 2/3x by 2/3 to isolate the variable

2/3x ÷ 2/3 = 4

what you do to one side you do to the other, so divide 4 by 2/3 as well, then you get

2/3x ÷ 2/3 is x

4 ÷ 2/3 is 12/2 which is equal to 6.

x=6

Answer:

I'm kind of confused what the question is asking. If they are asking for an expression to represent JL then the answer is 14x -32. If they want to know the distance between J and L then the answer is 66

Step-by-step explanation:

First I set the 2 equations equal to each other (5x-2 = 9x -30) and solved this to get x =7. (ANSWER ONE)

Next I plugged 7 into one of the equations (in this case either one will work bc JK and KL are the same distance. so I plugged 7 into the first one ( 5(7) -2 ) and I got 33. This means the distance of JK (and KL since they are equal) is 33.

Next I multiplied 33 by 2 since JL is JK and KL combined ( JK and KL are both 33 and therefore adding them together (multiplying 33×2) will give you the length of JL) and I got 66 (ANSWER 2)

Step-by-step explanation:

Answer: The average speed is 3m/s.

Step-by-step explanation:

We can define the average speed as the quotient between the total distance traveled in a given period of time, and that period of time,

Here we have that:

d = distance

t = time.

"A lioness hunting antelope runs a distance of 60 m in 15 s"

1) d = 60m, t = 15s

"Then she stops to survey the herd for 20 s"

We add 0 meters to the distance, and 20 seconds to the time.

2) d = 60m + 0m, t = 15s + 20s = 35s

"she trots for 25 s over 60 m around the edge of the herd."

we add 60m to the distance, and 25s to the time

3) d = 60m + 60m = 120m, t = 35s + 25s = 60s.

"Finally, the lioness races after the antelope, traveling 120 m in 20 s"

we add 120m to the distance and 20s to the time.

4) d = 120m + 120m = 240m, t = 60s + 20s = 80s.

Then the average speed of the lioness in that period of time is:

S = 240m/80s = 3m/s

Answer:

Step-by-step explanation:

The length of the diagonal of the square rounded to the nearest foot is 141.2 feet.

The area of a square is a product of it's any two sides or a product of diagonals divided by two. If the side has a length then the diagonal is a√2.

The perimeter of a square is the sum of the lengths of all the sides.

Given, A square garden has sides 100 ft long.
Now, If we draw a diagonal it becomes a right-angled triangle with a height of 100 ft and a base of 100 feet.

Therefore, By applying Pythagoras' theorem we have,

The length of the diagonal is = √(100² + 100²).

= √(10000 + 10000).

= √(20000) feet.

= 141.42 Or 141 feet.
