find the sum 6/10 + 5/10

Answer:

Yes, this is a function.

Step-by-step explanation:

This is a function because every input goes to exactly one output. Although 1 is listed twice in this example, it still goes to the same output of 15.

Negative numbers closest to 0 are the greatest.

-7/10 is farther away from 0 than -4/5 is.

-7/10 < -4/5, so -4/5 is the bigger fraction.

Answer:

A. is the correct answer.

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

The y intercept is -3 because -15/5=-3

The obtained coordinates are matching with graph B. Therefore, option B is the correct answer.

The given equation is -3x + 5y = -15.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Rearrange the given equation that is 5y = -15+3x

y= 3/5 x - 3

Put x=0, y=0-3

y=-3

Put x=5, y=3-3

y=0

Now, the coordinates to plot graph are (0, -3) and (5, 0).

The obtained coordinates are matching with graph B. Therefore, option B is the correct answer.

Step-by-step explanation:

Answer:

m<1 = 39

m<2 = 51

Step-by-step explanation:

For this problem, you need to understand that a little square in the bottom of two connecting lines represents a right-angle (an angle this 90 degrees).  This problem, gives you two relationships for angle 1 and angle 2 within a right-angle.  Using this information, we can solve for the measures of the two angles.

Let's write the two relations:

m< 1 = 3x

m< 2 = x + 38

And now let's right an equation that represents the two angles to the picture:

m<1 + m<2 = 90

Using this information, let's substitute the expressions we have for the two angles and solve for x.  Once we have the value of x, we can find the measure of the two angles.

m< 1 + m< 2 = 90

(3x) + (x + 38) = 90

3x + x + 38 = 90

x ( 3 + 1 ) + 38 = 90

x ( 4 ) + 38 = 90

4x + 38 = 90

4x + 38 - 38 = 90 - 38

4x = 90 - 38

4x = 52

4x * (1/4) = 52 * (1/4)

x = 52 * (1/4)

x = 13

Now that we have the value of x, we simply plug it back into our expressions for the m<1 and m<2.

m<1 = 3x = 3(13) = 39

m<2 = x + 38 = 13 + 38 = 51

And we can verify this is correct with the relational equation:

m<1 + m<2 = 90

39 + 51 ?= 90

90 == 90

Hence, we have found the values of m<1 and m<2.

Cheers.

Answer:

4.93 seconds

Step-by-step explanation:

The height y in feet of water t seconds after its release is given by the equation as follows :

[tex]y=-16t^2-2t+400[/tex]

We need to find the taken taken for the water to reach the ground. When it reach the ground, y will be equal to 0. So,

[tex]-16t^2-2t+400=0[/tex]

Above is a quadratic equation whose solutions can be calculated as follows :

[tex]t=\dfrac{-(-2)\pm \sqrt{(-2)^2-4\times (-16)\times 400} }{2\times (-16)}\\\\t=\dfrac{-(-2)+ \sqrt{(-2)^2-4\times (-16)\times 400} }{2\times (-16)}, \dfrac{-(-2)- \sqrt{(-2)^2-4\times (-16)\times 400} }{2\times (-16)}\\\\t=-5.062\ s\ \text{and}\ 4.93\ s[/tex]

Neglecting negative value.

Hence, it will take 4.93 seconds for the water to reach the ground

Step-by-step explanation:

Answer:

1 2/9 minutes

Step-by-step explanation:

55 mph

55 / 60 = 11/12

11/12 of a mile = 1 minute

45 mph

45 / 60 = 3/4

3/4 of a mile = 1 minute

11/12 divided by 3/4

11/12 * 4/3

We can cross-cancel

11/3 * 1/3 = 11/9 = 1 2/9

It takes 1 2/9 minutes for the hummingbird to cross the lake

Hope this helps!

(Please let me know if I did something wrong!)

The hummingbird will take 1 minute 13 seconds.

Let the time that will be taken by the hummingbird be represented by x

Note that 1 minute = 60 seconds

Based on the information given, the equation that'll be used in the question will be:

45/55 = 60/x

Cross multiply

(45 × x) = (60 × 55)

45x = 3300

x = 3300/45

x = 73.33 seconds

x = 1 minute 13 seconds

The hummingbird will take 1 minute 13 seconds.
