Answer:

[tex]d3=13.125[/tex] [tex]miles[/tex]

Step-by-step explanation:

Given data:

[tex]total[/tex] [tex]distance = 21[/tex] [tex]miles[/tex]

[tex]s1=8[/tex] [tex]miles/hr[/tex]

[tex]s2=8[/tex] [tex]miles/hr[/tex]

[tex]s3=10[/tex] [tex]miles/hr[/tex]

First we have to find out the how much time it takes when Supria and Elle meet.

As we know,

[tex]Displacement=rate*time[/tex]

[tex]d1=s1*t[/tex]

[tex]d2=s2*t[/tex]

[tex]d1+d2=21[/tex]

[tex]8t+8t=21[/tex]

[tex]16t=21[/tex]

[tex]t=21/16[/tex]

Now we can find that how much the third friend had traveled during this time period

[tex]d3=s3*t[/tex]

[tex]d3=10*21/16[/tex]

[tex]d3=13.125[/tex] [tex]miles[/tex]

Answer:

Reflect the parent function over the x-axis, and translate it 8 units to the left.

Step-by-step explanation:

The given function is

[tex]y = - \sqrt{x + 8} [/tex]

The parent function is

[tex]y = \sqrt{x} [/tex]

Since there is a negative multiply the transformed function, there is a reflection in the x-axis.

Since 8 is adding, within the square root, there is a horizontal translation of 8 units to the left.

Therefore to graph the given function, reflect the parent function over the x-axis, and translate it 8 units to the left.

Take the reflection of the graph about the x-axis and then translate the graph of the function by 8 units in the left direction and this can be determined by using the rules of transformation.

Given :

Function  --  [tex]\rm y = - \sqrt{x+8}[/tex]

The following steps can be used in order to determine the correct statement:

Step 1 - The parent function is given below:

[tex]\rm y = \sqrt{x}[/tex]

Step 2 - Now, draw the graph of the parent function.

Step 3 - Take the reflection of the graph about the x-axis. So, the function becomes:

[tex]y =- \sqrt{x}[/tex]

Step 4 - Now, translate the graph of the function obtained in the above step by 8 units in the left direction. So, the function becomes:

[tex]y = -\sqrt{x+8}[/tex]

Therefore, the correct option is D).

x = 83°

Solution:

The reference image to the answer is given below.

Sum of the adjacent angles in a straight line = 180°

⇒ ∠1 + ∠2 + ∠3 = 180°      (Refer image)

⇒ 56° + ∠2 + 41° = 180°

⇒ 56° + 41° + ∠2 = 180°

⇒ 97° + ∠2 = 180°

⇒ ∠2 = 180° – 97°

⇒ ∠2 = 83°

In the given image ∠5 and ∠2 are vertically opposite angles.

Vertical angle theorem:

Vertically opposite angles are equal.

⇒ ∠5 = ∠2

⇒ x = ∠2

⇒ x = 83°

Hence the measure of angle x is 83°.

Final answer:

Bees can see 4 out of the 6 pure spectral colors, which simplifies to the fraction 2/3 after removing the 2 colors they cannot see, orange and red.

Explanation:

The question involves calculating a fraction, which is a basic mathematical concept. We are told there are 6 pure spectral colors: red, orange, yellow, green, blue, and violet. Bees cannot see orange or red, so we must find out what fraction of the 6 pure spectral colors bees can see. We subtract the 2 colors bees can't see (orange and red) from the total of 6, leaving us with 4 colors they can see which are yellow, green, blue, and violet.

To express this as a fraction, we take the number of colors bees can see (4) and place it over the total number of pure spectral colors (6). Therefore, the fraction of pure spectral colors that bees can see is 4/6. This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 2. Thus, the simplified fraction is 2/3.

Answer:

He have 47 ducks and 7 cows.

Step-by-step explanation:

Given:

Farmer Jones raises ducks and cows.

He looks out his window and sees 54 animals with a total of 122 feet.

Now, to find the each type of animal he have.

Let the number of ducks be [tex]x.[/tex]

And the number of cows be [tex]y.[/tex]

So, total number of animals are:

[tex]x+y=54[/tex]

[tex]x=54-y[/tex]  ....( 1 )

As, the feet of cows are 4 and ducks are 2.

Now, the total number of feet are:

[tex]2(x)+4(y)=122[/tex]

[tex]2x+4y=122[/tex]

Substituting the value of [tex]x[/tex] from equation (1) we get:

[tex]2(54-y)+4y=122[/tex]

[tex]108-2y+4y=122[/tex]

[tex]108+2y=122[/tex]

Subtracting both sides by 108 we get:

[tex]2y=14[/tex]

Dividing both sides by 2 we get:

[tex]y=7.[/tex]

The number of cows = 7.

Now, to get the number of ducks we substitute the value of [tex]y[/tex] in equation (1):

[tex]x=54-y\\x=54-7\\x=47.[/tex]

The number of ducks = 47.

Therefore, he have 47 ducks and 7 cows.

Answer:

B

Step-by-step explanation:

The coordinates of C’ is (-5,3), the correct option is A.

When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.

If you study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.

Thus, if you're reflecting a point (x,y) along x axis, then its x

abscissa will stay same but y

ordinates will negate. Thus (x,y) turns to (x, -y)

Similarly, if you're reflecting a point (x,y) along y axis, the resultant image of the point will be (-x,y)

Given;

On a coordinate plane, trapezoid A B C D has points (2, 1), (3, 5), (5, 3) and (3, 1).

Now,When a point is reflected across the y-axis, the rule is:

(x,y)→ (-x,y)

C (5.3)= C' (-5,3)

Therefore, the reflection on C will be C (5.3) C' (-5,3).

Two or more expressions with an Equal sign is called as Equation.

Given that a submarine’s descent can be represented as y = -240x, where y is the elevation and x is time in hours.

We need to find the the time it will take this submarine to make the descent to the seafloor 2,100 feet below the surface

Since the submarine to make the descent to the seafloor 2,100 feet below the surface

So y = - 2100

So y = - 240x gives

Divide both sides by -240

x=8.75

Hence, 8.75 hours will be taken by the submarine to make the descent

The age of Noelle's dad is 54 years and that of Noelle is 20 years.

Step-by-step explanation:

Let the age of Noelle's dad is x years and that of Noelle is (74 - x) years.

{Since, the sum of their ages is 74}

Now, given that the age of Noelle's dad is 6 less than 3 times Noelle's age.

So, 3(74 - x) - 6 = x

⇒ 4x = 222 - 6 = 216

⇒ x = 54

So, the age of Noelle's dad is 54 years and that of Noelle is (74 - 54) = 20 years. (Answer)

To write the given expression (4f-3+2g)-(-4g+2) in standard form, change the signs of the terms subtracted and combine like terms to simplify to 4f + 6g - 5.

To write the expression in standard form, you need to simplify the expression by combining like terms and handling the subtraction of negative numbers properly. Given the expression (4f-3+2g)-(-4g+2), you first remove the parenthesis while changing the signs of the terms inside the parenthesis being subtracted.

The expression -(-4g+2) will become +4g-2 once we apply the rule that subtracting a negative is the same as adding a positive, similarly to the example 2-(-6)=2+6=8.

Now the expression is simplified to 4f - 3 + 2g + 4g - 2. We combine like terms to get 4f + 6g - 5.

The standard form of the given expression is 4f + 6g - 5.

The expression (4f-3+2g)-(-4g+2) can be simplified using the distributive property and combining like terms.

First, distribute the negative sign to the terms inside the parentheses: (-1) * (-4g) = 4g and (-1) * 2 = -2.

The expression becomes (4f-3+2g) + (4g-2).

Next, combine like terms: 4g + 2g = 6g, and -3 - 2 = -5.

The final expression in standard form is 4f + 6g - 5.

Water begins draining from a tank when the tank has 15 gallons of water in it.

Now, if we define f(w) as a function that represents the number of gallons of water remains in the tank after w pounds of water that have drained from the tank since the tank started draining, then the function can be represented as

[tex]f(w) = 15 - \frac{w}{8345}[/tex]

Since, w pounds of water is equivalent to [tex]\frac{w}{8345}[/tex] gallons of water. (Answer)

(Recall that water weighs 8.345 pounds per gallon.)

Answer:

the answer is x=6 or x=-16

The correct answer is x = 6 or x = -16.

To find the roots of the quadratic function f(x) = x2 + 10x - 96, we need to solve the equation x2 + 10x - 96 = 0 using the quadratic formula.

Using the quadratic formula, x = (-b ± √(b2 - 4ac)) / 2a, where a = 1, b = 10, and c = -96, we get x = 6 or x = -16 as the roots of the function f(x).

Therefore, the correct answer is x = 6 or x = -16.
