Answer:

D

Step-by-step explanation:

Answer:

[tex]x\geq -4[/tex]

Step-by-step explanation:

So we have the inequality:

[tex]3(x+6)-2(x+2)\geq 10[/tex]

First, distribute:

[tex](3x+18)+(-2x-4)\geq 10[/tex]

Combine like terms:

[tex](3x-2x)+(18-4)\geq 10[/tex]

Add:

[tex]x+14\geq 10[/tex]

Subtract 22 from both sides:

[tex]x\geq -4[/tex]

And we're done!

Answer:

mass of copper in the resulting mixture = 104 grams of pure copper

Percent of the resulting mixture that is copper = 81.25%

Step-by-step explanation:

The complete question is

An alloy is a mixture of metals. Suppose that a certain alloy is made by mixing 50 grams of an alloy that contains 52% copper with 78 grams of pure copper. How many grams of copper are in the resulting mixture? What percent of the resulting mixture is copper?

The original alloy has a mass of 50 grams,

52% of this 50 grams is copper,

mass of copper = 0.52 x 50 = 26 grams

78 grams of pure copper added will bring the mass of copper to..

mass of copper = 26 + 78 = 104 grams of pure copper

After adding 78 grams of copper to the alloy, the resultant mass of the mixture will be = original mass of alloy + mass of the pure copper added

==> 50 + 78 = 128 grams

Percentage of the resulting mixture that is copper = (total mass of copper in the mixture/total mass of mixture x 100%)

==> 104/128 x 100% = 81.25%

Answer: 60 feet

Step-by-step explanation:

Fron the question, we have been told to use a scale factor of 1 inch:12 feet. This simply means that 1 inch has been represented to 12 feet of the actual dimension.

We are further told that a plastic toy bird has a wingspan of 5 inches. The actual bird wingspan will therefore be 5 multiplied by 12 feet and this will be:

= 5 × 12 feet

= 60 feet

A plastic toy bird that has a wingspan of 5 inches has an actual bird wingspan of 60 feet

M = (1.5, 2.5 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ [tex]\frac{1}{2}[/tex] (x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ ) ]

Here (x₁, y₁ ) = C(4, 6) and (x₂, y₂ ) = D(- 1, - 1) , thus

midpoint = [ [tex]\frac{1}{2}[/tex] (4 - 1) , [tex]\frac{1}{2}[/tex] (6 - 1 ) ] = (0.5(3), 0.5(5) ) = (1.5, 2.5 )

Answer:

$9,102

Step-by-step explanation:

Ingrid Sering sells two types of garden fountains on a straight commission basis. On one fountain that sells for $869, she gets a commission of $174. On the other fountain that sells for $1,260, she gets $252.During a 3-month selling season, Ingrid sold 19 of the lower-priced fountains and 23 of the higher-priced fountains. What were her total commissions for three months

From the question above, we have the following information:

On one fountain that sells for $869 = she gets a commission of $174( the lower-priced fountains)

On the other fountain that sells for $1,260 = she gets $252 ( the higher-priced fountains)

Ingrid sold 19 of the lower-priced fountains)

1 fountain sold = $174 of commission

19 fountains sold =

$174 × 19

= $3,306

She also sold 23 of the higher-priced fountains)

1 higher priced fountains = $252

23 higher priced fountains =

$252 × 23

= $5,796

Hence, the Total commission Ingrid made = Total commission on Lower priced fountains + Total commission on Higher priced fountains

= $3,306 + $5,796

= $9,102

Therefore, the total commission Ingrid made = $9,102

Answer:

[tex]M=(\frac{3}2},\frac{9}{2})[/tex]

Step-by-step explanation:

The midpoint is given by the formula:

[tex]M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

So we have the two endpoints A(3,7) and B(0,2).

Let's let (3,7) be x₁ and y₁ and let's let (0,2) be x₂ and y₂.

Therefore, our midpoint is:

[tex]M=(\frac{3+0}{2},\frac{7+2}{2})[/tex]

Add:

[tex]M=(\frac{3}2},\frac{9}{2})[/tex]

Or:

[tex]M=(1.5,4.5)[/tex]

And we're done!

Hope this helps!

Answer: (1.5,4.5)

Step-by-step explanation:

For midpoint i have a little cheer to remember the steps it goes," Midpoint, midpoint, what do you do? add them together and divide by two.

so using this problem as an example you would add the y coordinates and the x coordinates and get (3,9) then you divide X and Y by two.

So 3 divided by 2 is 1.5 so that is the X coordinate for the midpoint

and 9 divided by 2 is 4.5 so that is your Y coordinate for the midpoint.

Put it together and your answer is (3.5,4.5)

Answer:

The mapping diagram above is a function since there are no two values (integers) in the range (Set B) where there is only one value (integer) in the domain (Set A) mapped unto them

Step-by-step explanation:

By definition a function is an association between the individual elements within two sets such that all element in one set is mapped to precisely one element of the other set

In the given example, all the elements in Set A are mapped to exactly one element of the Set B

That is the function from A to B is the set C (-1, -4), (9, 5), (1, 4), whereby the first component of the ordered pair in the set C are the elements of the set A.

The mapping diagram above is a function since there are no two values in set B where there is only one value in Set A mapped to them.

Therefore, since the mapping diagram illustrates a 1 input to 1 output relationship, then it is a function.
