Which number sentence is true

Answer:

The first attached graph showing the plotted point (0, 3) represents Ramon's initial step.

Step-by-step explanation:

We are given that Ramon is graphing the function f(x) = 3(4)x and that he begins by plotting the initial value.

So if we will input 1 for the value of x and then evaluate the plot point.

Therefore, we will get the point (0, 3) as the answer for this initial step.

Also, the first attached graph here showing the plotted point (0, 3) represents Ramon's initial step.

Answer:

The graph that represent the initial step in the attached figure

Step-by-step explanation:

we have

[tex]f(x)=3(4^{x})[/tex]

we know that

The initial value is the value of the function when the value of x is equal to zero

so

For [tex]x=0[/tex]

substitute in the function

[tex]f(x)=3(4^{0})=3(1)=3[/tex]

therefore

The initial value is the point [tex](0,3)[/tex]

Answer:

A

Step-by-step explanation:

this is a standard right triangle 30-60-90

with legs 1 and [tex]\sqrt{3}[/tex] and hypotenuse 2, hence

s = [tex]\sqrt{3}[/tex] and h = 2

Answer:

A. [tex]\sqrt{3}[/tex] ; 2

Step-by-step explanation:

Since We have all the angles of the triangle and one side we can use SIN, COS, and TAN to find the missing side lengths. SIN which is [tex]sin(x) = \frac{opposite}{hypotenuse}[/tex] can be used to find the hypotenuse

[tex]sin(30) = \frac{1}{h}[/tex]

[tex]\frac{1}{sin(30)} = \frac{h}{1}[/tex] ..... inverse both sides

[tex]\frac{1}{sin(30)} = h[/tex]

[tex]2 = h[/tex]

Now we can use the Pythagorean theorem to find the missing length. The Pythagorean Theorem is [tex]a^{2} +s^{2} = h^{2}[/tex]. So we just plug in the values we already have and solve for s.

[tex]1^{2} +x^{2} = 2^{2}[/tex]

[tex]1+s^{2} = 4[/tex]

[tex]s^{2} = 3[/tex]

[tex]s = \sqrt{3}[/tex]

In Conclusion, s = [tex]\sqrt{3}[/tex] and h = 2

Answer:

74.30

Step-by-step explanation:

Let s = entry price for a student

Let t = entry price for a teacher

4s +5t = 95

6s+10t = 173

I will use elimination to solve this problem.

Multiply the first equation by -2

-2(4s +5t) = -2*95

Distribute

-8s - 10t = -190

Add this equation to the second equation to eliminate t

-8s - 10t = -190

6s+10t = 173

----------------------

-2s = -17

Divide by -2

-2s/-2 = -17/-2

s = 8.50

Now we need to find t

4s +5t = 95

Substitute s=8.50

4(8.50) +5(t) = 95

34 +5t = 95

Subtract 34 from each side

34-34 +5t = 95-34

5t = 61

Divide by 5

5t/5 = 61/5

t = 12.20

We want to find the cost for 3 students and 4 teachers

3s+4t

3(8.50) + 4(12.20)

25.50 + 48.80

Answer: [tex]50^{\circ}[/tex]

Step-by-step explanation:

By the definition  of quadrilateral,

A quadrilateral has four interior angles and the sum of all interior angle of a quadrilateral is always equal to [tex]360^{\circ}[/tex]

Here the measurements of three interior angles are [tex]85^{\circ}[/tex], [tex]105^{\circ}[/tex] and [tex]120^{\circ}[/tex]

Let the measurement of fourth angle is x degree.

Thus,  [tex]85^{\circ}+105^{\circ}+120^{\circ}+x=360^{\circ}[/tex]

[tex]310^{\circ}+x=360^{\circ}[/tex]

[tex]x = 360^{\circ}-310^{\circ}=50^{\circ}[/tex]

Thus, the measure of fourth angle is [tex]50^{\circ}[/tex]

The measure of the 4th angle is 50 degrees.

To find the measure of the fourth angle of a quadrilateral, we need to know that the sum of all the interior angles of a quadrilateral is always 360 degrees. Therefore, to find the measure of the fourth angle, we can subtract the sum of the other three angles from 360. In this case, the given angles are 85, 105, and 120 degrees, so the sum of these three angles is 85 + 105 + 120 = 310 degrees. To find the measure of the fourth angle, we subtract 310 from 360: 360 - 310 = 50 degrees.

Answer:

(6, -3)

Step-by-step explanation:

I will solve this system using elimination.

[tex][tex]\left \{ {{-x+2y=-12} \atop {2x+3y=3}} \right.[/tex][/tex]

I will multiply [tex]-x+2y=-12[/tex] by 2 so that -x becomes -2x.

2(-x + 2y = -12)

Distribute.

-2x + 4y = -24

Now subtract this from the other equation.

2x + 3y = 3

-2x + 4y = -24

        7y  =  -21

Divide both sides by 7.

y = -3

Now that we have the value of y, plug it into the original equation.

-x + 2(-3) = -12

Simplify.

-x - 6 = -12

Add 6 to both sides.

-x = -6

Divide both sides by -1.

x = 6

(6, -3)

Answer:

2 pens

Step-by-step explanation:

Let x represent the number of pens Linda buys.  Since they cost $2.65 each, this gives us the expression 2.65x.

Adding the cost of the card to this gives us the expression 2.65x+1.17.

She has a total of $9.00; this gives us the equation

2.65x+1.17 = 9.00

Subtract 1.17 from each side:

2.65x+1.17-1.17 = 9.00-1.17

2.65x = 7.83

Divide both sides by 2.65:

2.65x/2.65 = 7.83/2.65

x = 2.95

We cannot buy a portion of a pen, so the most she can buy is 2 pens.

Answer:

The answer is 2 pens.

Step-by-step explanation:

Total amount Linda has in her wallet = $9

Amount spent on buying a card = $1.17

So, amount left with Linda = [tex]9-1.17=7.83[/tex]

Now, she wants to buy pens that cost $2.65, so the maximum number of pens she can buy are = [tex]\frac{7.83}{2.65}= 2.9[/tex]

But, pens cannot be in decimal, so the maximum pens she can buy are 2.

Answer:

Step-by-step explanation:

Orange juice: $2.20 per bottle.

10 bottles of orange juice cost 10 * $2.20 = $22.00.

We subtract the cost of the 10 bottles of orange juice from the amount of money he has to find out the amount he will have left for bottles of apple juice.

$50.80 - $22.00 = $28.80

After buying the 10 bottles of orange juice, he has $28.80 left.

We divide the money he has left for apple juice bottles by the price of one apple juice bottle to find out the number of apple juice bottles he can buy.

$28.80/$2.40 = 12

He can buy 12 bottles of apple juice.

Subtract 18 from both sides

-2x + 18 - 18 = -12 - 18

-2x = -30

Divide both sides by -2

-2x/-2 = -30/-2

x = 15

Answer:

Bowl B contains 2 apples more than Bowl A and Bowl A contains 1 mango more than Bowl B.

Step-by-step explanation:

Number of apples in Bowl A = 6

Number of mangoes in Bowl B = 8

Difference in apples = 8 - 6 = 2

So, Bowl B contains 2 apples more than Bowl A.

Number of mangoes in Bowl A = 3

Number of mangoes in Bowl B =2

Difference in mangoes = 3 - 2 = 1

So, Bowl A contains 1 mango more than Bowl B.

Bowl B has 2 more apples and 1 fewer mango compared to Bowl A. Thus, the primary differences are in the quantities of apples and mangoes in each bowl.

Step by Step Solution:

To understand the differences between Bowl A and Bowl B, let's break down the contents of each bowl:

Bowl A contains 6 apples and 3 mangoes.

Bowl B contains 8 apples and 2 mangoes.

Now, let's find the differences in the number of apples and mangoes between the two bowls:

Difference in Apples: Bowl B has 8 apples, and Bowl A has 6 apples. Therefore, the difference is 8 - 6 = 2 apples. Bowl B has 2 more apples than Bowl A.

Difference in Mangoes: Bowl A has 3 mangoes, and Bowl B has 2 mangoes. Therefore, the difference is 3 - 2 = 1 mango. Bowl A has 1 more mango than Bowl B.

In summary, Bowl B has 2 more apples and 1 fewer mango compared to Bowl A.

Answer:

X=5 (Or (5,0))

Step-by-step explanation:

The Y intercept is when X=0

The X Intercept is when Y=0

Our equation is y=-4200x+21000

So let's rewrite it... First subtract 21,000 (Also, remember Y is 0)

0-21000=-4200x

-21000=-4200x

Now to get X alone, divide -21000 by -4200

This will give us 5=x, which is the same as x=5. There is your answer!

The slope means that the value decreases by -4,200 per year.

Here we have the linear equation:

y = -4,200x + 21,000

We know that this equation relates the value of something, y, after x years.

So a slope will tell us how many units does the value increase or decraeses each year.

Here the slope is -4,200, which means that the price decreases by -4,200 dollars each year.

Example with temperature:

The temperature -3 degrees is warmer than -5 degrees. This applies to celsius or fahrenheit. You might also write "negative 3 degrees" as "3 degrees below zero"; the same applies for -5. The absolute difference between the two temperatures is 2 degrees.

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

Example with money:

If your bank balance is -3 dollars and your friend's bank balance is -5 dollars, then your friend owes more money to the bank (s/he owes $2 more than you do).

Negative balances mean you are in debt. Another way to look at this is to consider you want to buy an item worth $10 but you only have $7. If the store owner lends you the difference, which you pay back later, then 7-10 = -3 is the amount of money on your balance sheet indicating you are in debt $3. The order of subtraction is important. Saying 10-7 = 3 shows a positive bank balance and you wouldn't be in debt (and still have $3 in your pocket).

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

In either example, the value -3 is to the right of -5 on the number line so we would write the inequality -3 > -5 to say that -3 is larger than -5. Have a look at the image attached below.

Answer:

88 cm

Step-by-step explanation:

The side of the square = 6 cm, so the shorter side of each rectangle = 6 cms.

The area of each rectangle =  36 *  1 1/3
