Step-by-step explanation:

Answer:

15 dogs

Step-by-step explanation:

dogs : cats : rabbits

5 : 2 : 1

? : ? : 3

1 rabbit = 2 cats

2 cats = 5 dogs

1 rabbit = 2 cats

2 rabbits = 4 cats

3 rabbits = 6 cats

2 cats = 5 dogs

4 cats = 10 dogs

6 cats = 15 dogs

Answer:

Sₙ = 57/2 * (504 + 896) = 39900

Step-by-step explanation:

first multiple of 7 after 500 is: 72 *7 = 504

last multiple of 7 before 900 is: 128 *7 = 896

a₁ = 504

aₙ = 896  

where n = 128-72 +1 = 57

sum of arithmetic sequence: Sₙ = n/2 * (a₁ + aₙ)

Sₙ = 57/2 * (504 + 896) = 39900

Answer:

x-4

Step-by-step explanation:

A negative base raised to an even power equals a positive.

So you're left with sqrt x-4 ^2

Then reduce the index of the radical and the exponent with 2

x-4

Hope this helps

The correct expression will be ( x- 4 ). So option B is right.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The expression will be solved as:-

E = ( - √(x-4))²

The product of two minuses is positive and the product of the same square root numbers will be the number so the equation will become.

E = -√(x-4) x -√(x-4)

E = x - 4

Therefore the correct expression will be ( x- 4 ). So option B is right.

Answer:

D because it on the same plane as abc so it is a coplanar. also I got it right on my test.

Point D is coplanar with A, B, and C because it is on the same plane as A, B, and C option (4) is correct.

It is defined as the six-faced shape, a type of hexahedron in geometry.

It is a three-dimensional shape. It is also called a cuboid.

It is given that:

A rectangular prism is given,

Geometry can be defined as the branch of mathematics that is concerned with the size, shape, and orientation of two-dimensional figures.

As we know in the rectangular prism there are eight vertices and six faces.

From the figure, we can see clearly that point D is coplanar with A, B, and C.

Point D is coplanar with A, B, and, C.

Thus, point D is coplanar with A, B, and C because it is on the same plane as A, B, and C option (4) is correct.

According to the question,

→ After 2 hours (t₁),

Juan is 110 miles (d₁) from his home.

→ After 5 hours (t₂),

Juan is 275 miles (d₂) from his home.

→ The average rate of change will be:

Answer:

64 and 125

Step-by-step explanation:

The amount of money in the bank contains 5 pennies, 9 nickels, 21 dimes, and 15 quarters.

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown.

First, let's find the number of pennies in the bank.

Since 10% of the coins are pennies, and there is 50 coins total, the number of pennies is :

10/100 × 50 = 5

Now let's find the number of dimes. Since 42% of the coins are dimes, and there is 50 coins total, the number of dimes is :

42/100 × 50 = 21

Since there are 4 more nickels than pennies, the number of nickels is :

5 + 4 = 9

Finally, the number of quarters is: 50 - 5 - 9 - 21 = 15

Thus, the bank contains 5 pennies, 9 nickels, 21 dimes, and 15 quarters.

Answer:

15xy-6x+5y-2

15xy+5y-6x-2

5y(3x+1) -2(3x+1)

(we pick one out of the (3x+1) brackets.

your final answer becomes:

(5y-2)(3x+1)

Answer:

(5y - 2)(3x + 1)

Step-by-step explanation:

Let's focus on those first two terms, 15xy and 6x. They have two factors in common, an x and a 3, giving them a greatest common factor of 3x. If we factor that out, the expression 15xy - 6x becomes 3x(5y - 2). Substituting that into our original expression, we get the new expression

[tex]3x(5y-2)+5y-2[/tex]

Let's group those last two terms to make our next step clearer:

[tex]3x(5y-2)+(5y-2)[/tex]

Now, each term has the factor (5y - 2) in common. We can pull it out to get the fully factored expression

[tex](5y-2)(3x+1)[/tex]

Answer:

[tex]1600\ \text{people per square mile}[/tex]

Step-by-step explanation:

Number of people per square mile in City A is 6000.

In terms of size City B is a dilation of City A with scale factor 1.5.

This means a length of 1 mile in city A would be 1.5 miles in city B.

So, [tex]1\ \text{mile}^2\text{ in City A}=1.5^2\ \text{mile}^2\text{ in City B}[/tex]

City B has [tex]\dfrac{3}{5}[/tex] of the population of City​ A.

So the population density of City B would be

[tex]\dfrac{\dfrac{3}{5}\times 6000}{1.5^2}=1600\ \text{people per square mile}[/tex]

The population density of City​ B is [tex]1600\ \text{people per square mile}[/tex].

Answer:

y = x^2 + 14x + 62

Step-by-step explanation:

y = (x + 7)^2 + 13 is to be rewritten in the form y = ax^2 + bx + c.  

Note:  Use " ^ " to denote exponentiation.

Expand y = (x + 7)^2, holding the constant term to be added on later:

y = x^2 + 14x + 49 + 13

Combining the constants, we get:

y = x^2 + 14x + 62 (which matches Answer D).

Answer:

m = 3/2

Step-by-step explanation:

You want to find the slope, or the change in y coordinates over change in x-coordinates.

The first given point is E(-2, -4)

The second point is F(2, 2)

Coordinates are given in (x, y), so following the equation and computing the  x and y coordinates of E - F for both the numerator and denominator:

[tex]\frac{y_2 - y_1}{x_2-x_1} = \frac{-4 -2}{-2 -2} = \frac{-6}{-4} = \frac{3}{2}[/tex]

You could also have went the other way and calculated F - E for the numerator and denominator and get the same answer.

Finally, to check you can also look at the graph through the rise over run (rise/run) method and see that from E, you go up 3 (rise) and to the right 2 (run) to get to the next point on the line.
