Answer:

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-4,-1) and (-3,-1)

The distance between them is

[tex]d = \sqrt{ ({ - 4 + 3})^{2} + ({ - 1 + 1})^{2} } \\ = \sqrt{ ({ - 1})^{2} } \\ = \sqrt{1} [/tex]

We have the final answer as

1 unit

Hope this helps you

Answer:

No, she does not.

Step-by-step explanation:

Using the words here, we can create the expression [tex]20d + 7[/tex] where d is the number of days.

We can now substitute 15 in as d, to see how much this will cost.

[tex]20\cdot15 + 7\\\\300+7\\\\307[/tex]

So the total cost will be $307.

Since $307 is more than $250, she does not have enough money.

Answer:

(-6,0)

Step-by-step explanation:

Whether we rotate a point 180° clockwise or counterclockwise, we'll always end up at the same point.

When we rotate a point by 180°, assuming the original point is [tex](x,y)[/tex], the new coordinate becomes [tex](-x,-y)[/tex].

So:

[tex](-6,-0)\\\\(-6,0)[/tex]

Answer:

c

Step-by-step explanation: A P E X

An experiment's or random trial's sample space is the set of all conceivable outcomes or results. The correct option is C.

A sample is a statistically significant subset of a larger population. The utilisation of samples enables researchers to conduct investigations with more manageable data and more quickly. Randomly chosen samples exhibit little bias if they are large enough, but obtaining such a sample can be costly and time-consuming.

Given that a population consist of 85,000 people. Now, the number of members of the population that being surveyed could result in a parameter but not a sample static is 8500. This is because a parameter is a value that describes a specific attribute of the population as a whole. A sample survey cannot provide this information. To determine the real value of a parameter, the entire population must be examined.

Hence, the correct option is 85,000.

Step-by-step explanation:

3 of the 4 rows of the figure are shaded, so that shading represents the fraction 3/4.

1 of the 4 columns of the figure is shaded, so that shading represents the fraction 1/4.

Where the shaded rows and column overlap, the product is represented. That product is ...

  3/4 × 1/4

Answer:

3/4 x 1/4

Step-by-step explanation:

it was right

Answer:

Step-by-step explanation:

Given the function f(x) = 12, the function is only a constant with no degree. For a function to have roots, it must have at least degree of 1. Let us write the function f(x) = 12 in terms of x

f(x) = 12x⁰

From the function above it can be seen that the introduction of x⁰ can not in any way affect the function of x because x⁰ will return 1.

From the function, it can be seen that the highest power of the variable x is zero. This means that the function has no roots.

Hence, there are no real zeros of the function.

Answer:

0.5 m³

Step-by-step explanation:

You have a rectangular prism and a cube.  Find the volume of each separately.  After solving, add the two volumes together to find the total volume.

Cube

The side length is 0.5 m.

V = a³

V = (0.5 m)³

V = 0.125 m³

Rectangular Prism

The height is 0.75 m, the width is 0.5 m, the length is 1 m.

V = lwh

V = (0.75 m)(0.5 m)(1 m)

V = 0.375 m³

0.125 m³ + 0.375 m³ = 0.5 m³

Step-by-step explanation:

The value of the first 5 is five hundred (500)

The value of the second is five thousand (5,000)

The place value of 5 in the number 25,578 is 500 and 5,000.

The value of each digit in a number is known as the place value. The 5 in 5,006 signifies 5 thousand, or 5,000, while the 5 in 350 represents 5 tens, or 50. Children must learn that while a digit can have the same value, its value changes depending on where it appears in the number.

A number is a numerical unit of measurement and labeling in mathematics. The first examples are the numbers 1, 2, 3, and 4.

The place value of 5 in the number 25,578 will be calculated as below:-

The value of the first 5 is five hundred 500.

The value of the second is five thousand 5,000.

Therefore, the place value of 5 in the number 25,578 is 500 and 5,000.

Paj is filling a 9-cubic-inch flower pot with soil from small bags. Each bag of soil contains 2 2/3  cubic inches of soil. Exactly how many bags of soil are needed for Paj to fill the flower pot?

Answer:

[tex]Number\ of\ Bags = 3\frac{3}{8}[/tex]

Step-by-step explanation:

Given

[tex]Flower\ Pot = 9 in^3[/tex]

[tex]Small\ Bag = 2\frac{2}{3} in^3[/tex]

Required

How many bag of soil can fill the flower pot

To solve this,we simply divide the volume of flower pots by the small bags. This is done as follows;

[tex]Number\ of\ Bags = \frac{Flower\ Pot}{Small\ Bag}[/tex]

[tex]Number\ of\ Bags = \frac{9 in^3}{2\frac{2}{3} in^3}[/tex]

Convert fraction

[tex]Number\ of\ Bags= \frac{9 in^3}{\frac{8}{3} in^3}[/tex]

[tex]Number\ of\ Bags = 9 in^3/\frac{8}{3} in^3[/tex]

[tex]Number\ of\ Bags = 9 * \frac{3}{8}[/tex]

[tex]Number\ of\ Bags = \frac{9 * 3}{8}[/tex]

[tex]Number\ of\ Bags = \frac{27}{8}[/tex]

[tex]Number\ of\ Bags = 3\frac{3}{8}[/tex]

Hence, the number of bags needed is  [tex]3\frac{3}{8}[/tex]

7 x 8 =  56

12 x 6 = 72

72+ 15 = 87

Hadley and Delaney therefore bought 128 markers all in total.

Hope I helped ! :))))))

The amount of markers Hadley and Delaney bought in all is equal to 128 markers.

Given  the following data:

To determine the amount of markers Hadley and Delaney bought in all:

First of all, we would determine the total number of marker in each box.

For Hadley:

[tex]Hadley = 7 \times 8[/tex]

Hadley = 56 markers

For Delaney:

[tex]Delaney = 6\times 12[/tex]

Delaney = 72 markers

Answer: They are both right triangles so you can use the Pythagorean Theorem to get the length of the missing side

12^2 = 144. 5^2 = 25. 144 + 25 = 169. 13^2 = 169. Or you could say the sure root of 169 is 13.

Step-by-step explanation:

The triangles are congruent because the three sides of triangle A are equal to the three sides of triangle B.

In geometry they call that proof "sss" meaning 3 same sides. Or you could prove by "sas" 2 equal sides and an equal angle.

[tex]g(x)= x^2\\\\g(-6)=(-6)^2\\\\g(-6)=36[/tex]

so g(-6)=36

so we need to find f(36)

[tex]f(x)=\sqrt{x+4} \\\\f(36)=\sqrt{36+4} \\\\f(36)=\sqrt{40}\\\\f(36)=\sqrt{4}* \sqrt{10} \\\\f(36)=2\sqrt{10}[/tex]

Answer:

C. 21

Step-by-step explanation:

We use the Power of Point theorem, which states that for points A, B, C, D, and E oriented in the way shown in the attachment:

BC * AC = DC * EC

Here:

AC = AB + BC = (2x + 5) + 9 = 2x + 14

BC = 9

DC = 10

EC = KC = (1 + 2x) + 10 = 2x + 11

So plug all these in:

BC * AC = DC * EC

9 * (2x + 14) = 10 * (2x + 11)

18x + 126 = 20x + 110

2x = 126 - 110 = 16

x = 8

Put this back into the expression for AB:

AB = 2x + 5 = 2 * 8 + 5 = 16 + 5 = 21

The answer is thus C.

Step-by-step explanation:

A. England = 5.60*10000000

=56000000

B. Wale = 3.14*1000000 = 3140000

Scotland = 5.44*1000000 = 5440000

Northern Ireland = 1.88*1000000 =1880000

Total = 10460000

In standard form =1.046*10^7

C. Total population as at 2018 = 66460000

expected population by 2041 = 72900000

increase or change = (72900000 - 66460000) = 6440000

% change = (6440000/66460000)*100
