Step-by-step explanation:

The way I look at it I think 10.00 cause it says I had in the beginning k and it says what people gave me and at the end it says what I had as well so I had 5.00 in the beginning and then I had another 5.00 so that makes it 10.00 in all realatly really let me know if I'm right as it's the only thing that makes since with it all..... lol so the answer is 10.00.... so if it would of said how much do I have all together then it would be what my granddaughter said but it didn't. It's a tricky question here and a good one to get people thinking on it haaa haaa

(16^3/2)^1/2

We know that a^ b^c = a^(b*c)

16 ^(3/2*1/2)

16 ^3/4

Now rewriting 16 as 2^4

2^4^3/4

Answer:

x = 11

Step-by-step explanation:

(-x + 11)(x + 3)= 0

-x + 1 1 = 0 or x+3 = 0

-x = -11 or x = -3

x=11 or x=-3 (rejected cos negative)

Answer:

B. 6.

Step-by-step explanation:

When x = 3 the prediction is 2.5(3) - 1.5

= 6.

The value of y at x = 3 is,

⇒ y = 6.0

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

A data set consists of the following data points:

⇒ (2, 4),(4, 7), (5, 12)

And, The line of best fit has the equation;

⇒ y = 2.5x - 1.5.

Now, At x = 3;

⇒ y = 2.5x - 1.5.

⇒ y = 2.5 × 3 - 1.5.

⇒ y = 7.5 - 1.5

⇒ y = 6.0

Thus, The value of y at x = 3 is,

⇒ y = 6.0

Answer:

95 ft 10 in

Step-by-step explanation:

We need to add the lengths of the front of the house and both sides of the house:

50 ft 8 in + 2(22ft + 9in)

= 50ft + 8 in + 44ft + 18in

= 94ft + 22in

12 inches = 1 foot

22 inches = 1 ft 10 in

Therefore, the length of the gutter he must buy must be:

94 ft + 1 ft + 10 in

= 95 ft 10 in

The question is incomplete. find the complete question below;

A given line has the equation 2x + 12y = −1. What is the equation, in slope-intercept form, of the line that is perpendicular to the given line and passes through the point (0, 9)? y = ( )x + 9

The equation of a line is represented as y = mx+c where m is the slope and c is the intercept. our ficus is to get both the slope and the intercept and then substitute then into the equation of the line.

First let us get the slope of the known line:

Rewriting the equation 2x + 12y = −1 in its standard form, we have;

12y = -2x-1

y = -1/6 x - 1/12

the slope of the line is -1/6

Since this line is perpendicular to the unknown line, the slope of the unknown line say M = -1/(-1/6) = 6

For the intercept

we will substitute the point (0,9) and the slope M = 6 into the equation

y = Mx+c to get the value of the intercept.

9 = 6(0)+c

c = 9

Finally, we will find the equation of the line perpendicular to the given line using the equation y = mx+c

Substituting m = 6 and c = 9 into the equation, we have y = 6x+9 or y-6x = 9

The unknown equation in slope intercept form is y=6x+9

The new equation of the perpendicular line is y = 6x + 9.

The slope of the line is determined from the given equation of the line.

[tex]2x + 12 y = -1\\\\12y = -1 - 2x\\\\y = \frac{-1}{12} - \frac{2x}{12} \\\\y = \frac{-1}{12} - \frac{x}{6}\\\\M = \frac{-1}{6}[/tex]

[tex]M_1 = \frac{-1}{M} = \frac{-1}{-1/6} = 6[/tex]

[tex]y = mx + c\\\\9 = 6(0) + c\\\\9 = c\\\\y = 6x + 9[/tex]

The complete question is below:

Answer:

80 (I think)

Step-by-step explanation:

I would just go to x=7 and look up until i reach the line of best fit. The intersection is at y=80

The score of student is 80 marks if she studied for 7 hours.

Given,

The scatter plot shows the time spent studying compared to test scores for Mr. Stone’s eighth-grade class. From the plot it is clear that time is shown on x  axis and test scores is shown on Y axis.

We have to predict the score that a student would earn if he studied for 7 hours.

Here look at the Scatter plot we find that 7 hours is on x axis and the respective line of best fit of test score is passing through score 80.

Hence if a student is studied for 7 hours he would earn 80 marks.

This is not a perfect square

Answer:

1/8 = 12.5%

Step-by-step explanation:

There are 8 letters in the word MONASTIC.  One of the letters is A.

So the probability is 1/8, or 12.5%.

Let's start with sectioning off the little squares on the left that are jutting out of the top and bottom. Both of the squares are C*E, so multiply C*E twice to get the area of those little squares. That comes out to 12 feet.

Next is the main quadrilateral, the big one. You have to cut it off at the point the triangle starts to slope, so the end fo B.

But you also have to get the left part, so you have to add the length of C to the length of B to get the length of the quadrilateral. A encompasses the entire height, but not the part we want, because we already isolated those little squares. To get the height, just subtract the two E parts. The height is 6. The length is 8 feet. Multiply and get 48.

Add that to the previous 12 feet calculated to get 60.

Next, the triangle. The height is A, but only with one E. So subract the other E to get a height of 9. The length is D, but you have to subract B because that is part of the earlier quadrilateral. That makes it 9.

The formula for a triangle is height * length / 2. So, plug in the numbers-- 9 * 9 / 2

81/2

40.5.

Add to the previous 60 we got and that makes 100.5 square feet.

Answer:

98 °

Step-by-step explanation:

We know that the sum of the angles in a triangle is 180. We also know that angle DAB is 122°, meaning that angle CAB is 180-122, which is 58°. We also know that angle CBA is 24 degrees. Therefore, angle x is just 180-(58+24), which is 98

Answer:

V=πr2h

3

Step-by-step explanation:

Answer:

15 cm³

Step-by-step explanation:

The formula for the volume of a cone is:

V = πr²h /3

where r is the radius and h is the height

Let's substitute the given values into this equation:

V = πr²h /3

(Remember that the base of a cone is a circle and the formula for the area of a circle is πr²)

V = πr²h /3

V = (5)(9/3)

Solve:

V = (5)(9/3)

V = (5)(3)

V = 15

Therefore, the volume of the cone is 15 cubic centimeters.
