Answer:

1.48 m

Step-by-step explanation:

In a class of 32 students

the mean height of the 14 boys is 1.56 meters.

the mean height of all 32 students is 1.515 meters.

Total number of students = 32

Mean height of all students = 1.515

We can obtain the sum of all student's height :

Number if students * mean height

= 32 * 1.515

= 48.48

Number of boys = 14

Mean height of boys = 1.56m

We can obtain the sum of all boys height :

Number if students * mean height

= 14 * 1.56

= 21.84

Number of girls :

All students - Number of boys

32 - 14 = 18

Sum of girls height :

48.48 - 21.84 = 26.64

Mean height of girls :

Sum of girls height / Number of girls

26.64 / 18

= 1.48 m

Answer:

The way to do is dow below

Step-by-step explanation:

You may be asked to "determine algebraically" whether a function is even or odd. To do this, you take the function and plug –x in for x, and then simplify. If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even.

An angle is a figure created by two rays. The value of x is 10 units.

An angle is a figure created by two rays, known as the sides of the angle, that have a common terminus, known as the vertex of the angle.

The line VT bisects ∠STU, therefore, the two triangles will be similar because VT is the common line between the two triangles while ∠STV and ∠UTV are equal angles. Therefore, we can write,

[tex]\dfrac{UT}{UV} = \dfrac{ST}{SV}\\\\\dfrac{3x+2}{24} = \dfrac{12}{9}\\\\3x+2 = \dfrac{12 \times 24}{9}\\\\\\3x+2=32\\\\x=10[/tex]

Hence, the value of x is 10 units.

Answer:

x = 8, y = -5

Step-by-step explanation:

Multiplying the 2nd equation by 3, we get -3x-9y = 21. Then eliminating with the first equation we get -5y = 25. y = -5. Substituting this into the original equation, we get x = 8.

Answer:

x=8  y=-5

Step-by-step explanation:

3x+4y=4                   3x+4y=4

3(-x-3y=7)=              -3x-9y=21

-3x-9y=21                      -5y=25

                                       y=-5

3x+4(-5)=4

3x-20=4

3x=24

x=8

Answer: C

Step-by-step explanation: The $25 is added on to the constant rate of $5.25. This means that it would be $5.25 + $25 > $250

Answer:

C

Step-by-step explanation:

$5.25 is affected by the number of hours she baby sits, so it needs to have an h next to it to show that, that makes B and D incorrect.

You need to add 25 to the total, not subtract it, so A is also incorrect. that leaves C

Given:

Weekly salary of Joe = $350

Commission of sales = 10%

Total sales of last week = $1,000.

To find:

The the total money did joe make.

Solution:

We have,

Commission of sales = 10%

Total sales of last week = $1,000

[tex]\text{Commission}=10\%\text{ of }1000[/tex]

[tex]\text{Commission}=\dfrac{10}{100}\text{ of }1000[/tex]

[tex]\text{Commission}=100[/tex]

Now,

Total weekly income = Weekly fixed salary + Commission

                                   [tex]=350+100[/tex]

                                   [tex]=450[/tex]

Therefore, the total income of Joe for last week is $450.
