PLEASEEEE HELPP PLEASEEEE!! which one represents -7pi/3

Answer:

a). f(0) = 4

b). f(6) = 8

Step-by-step explanation:

a). When x < 5, piecewise function to be considered,

f(x) = x + 4

Since, x = 0 is less than x = 5

f(0) = 0 + 4

f(0) = 4

b). When 5 ≤ x < 7,

Piecewise function to be considered,

f(x) = 8

Therefore, for x = 6,

f(6) = 8

Answer:

The perimeter is the distance around the triangle. Given the ratio, the perimeter using the ratio is;

= 3 + 4 + 5

= 12 units

a. 12 units = 240 cm

The perimeter in centimetres is 240cm and in ratio is 12 units so they are equivalent.

b. 1 unit = 20 cm

If 12 units are to 240 cm, 1 unit is;

= 240/12

= 20 cm

c. Length of red side;

Red side has length of 5 units. 1 unit is 20 cm.

Length in cm is;

= 5 * 20

= 100 cm

Answer:

50 hombres y 25 mujeres

Step-by-step explanation:

Sea m el número de hombres y w el número de mujeres.

El total es 75

Así; m + w = ​​75 •••••••• (i)

Además; 16% de m + 20% de w = 13

0,16 m + 0,2 w = 13

Multiplicar por 100

16m + 20w = 1300 ••••• (ii)

De i, m = 75-w 16 (75-w) + 20w = 1300

1200 - 16w + 20w = 1300

4w = 1300-1200

w = 100/4 w = 25

Recordar; w + m = 75

25 + m = 75

m = 75-25

m = 50

Answer:

d

Step-by-step explanation:

155$ after 3 months means 45$ less. 45$ divided by 3 (the number of months) =15

that means she spends 15$ per month

Answer:

The correct option is;

0.28

Step-by-step explanation:

The given parameters are;

The mean score for Michael, [tex]\bar x _1[/tex] = 150

The standard deviation, σ₁ = 30

The mean score for Alan,  [tex]\bar x _2[/tex] = 165

The standard deviation, σ₂ = 15

Taking n₁ = n₂ = 1

[tex]z=\dfrac{(\bar{x}_{1}-\bar{x}_{2})-(\mu_{1}-\mu _{2} )}{\sqrt{\dfrac{\sigma_{1}^{2} }{n_{1}}-\dfrac{\sigma _{2}^{2}}{n_{2}}}}[/tex]

Taking μ₁ - μ₂ = 0

[tex]z=\dfrac{(150-165)}{\sqrt{\dfrac{30^{2} }{1}-\dfrac{15^{2}}{1}}} \approx -0.577[/tex]

The p-value for a z-score of -0.577 from the z-table is 0.28434

Therefore, the probability that Michael, with mean score, [tex]\bar x _1[/tex] = 150 will have a greater score than Alan, with a mean score of [tex]\bar x _2[/tex] = 165 is 0.28434 ≈ 0.28

Therefore, the correct option is 0.28

You answer is going to be: 540

Answer:

I think answer is A

Step-by-step explanation:

Cause you notice time is the x and distance (meters) is the y. So 1 minute = 200 meters.

Answer:

a = -1

Step-by-step explanation:

-6(3a+4) = 3a-3

-18a-24 = 3a-3

-24+3 = 3a+18a

21a = -21

a = -21 ÷ 21

a = -1

Answer:

No, it could be caused by seocnd hand smokeing also.

Step-by-step explanation:

Answer:

False.

Step-by-step explanation:

Tobacco use not only affects the person using it but also those around them. Secondhand smoke is the smoke that is exhaled by a smoker or that comes from the burning end of a cigarette, cigar, or pipe. Secondhand smoke contains more than 7,000 chemicals, including hundreds that are toxic and at least 70 that can cause cancer. Breathing in secondhand smoke can lead to a range of health problems, especially in children and non-smoking adults. These can include lung cancer, heart disease, stroke, respiratory infections, and asthma. Additionally, exposure to secondhand smoke during pregnancy can cause low birth weight, premature birth, and sudden infant death syndrome (SIDS). Therefore, it is important to create smoke-free environments to protect the health of everyone, including non-smokers.

Answer:

A. Charlie

B. Charlie used 48 more beads than Shaniqua

Step-by-step explanation:

Charlie:

25 necklaces with 96 beads in each necklace.

Total beads used = number of beads per necklace × number of necklace

= 96 × 25

= 2,400 beads

Shaniqua:

28 necklaces with 84 beads in each necklace.

Total beads used = number of beads per necklace × number of necklace

= 84 × 28

= 2,352 beads

A. Charlie used more beads

B. 2,400 beads - 2,352 beads= 48 beads

Charlie used 48 more beads than

Shaniqua

Step 1: Define Systems

y = -7x + 6

y = -10x

Step 2: Solve for x

Substitution

Step 3: Solve for y

Answer:

x = -2

y = 20

Step-by-step explanation:

y = -7x + 6

y = -10x​

y = -10x

-7x + 6 = -10x

3x = -6

x = -2

y = -7x + 6

y = -7 ( -2 ) + 6

y = 14 + 6

y = 20

Answer:

3 cookies/bag

Step-by-step explanation:

First of all, let's define a unit rate. A unit rate is a ratio of the amount of one measurement to one unit of another measurement term. Unit rates can be expressed as fractions.

Now, here is something easier for you to remember: the second unit always have to be something with the quantity of 1.

In this case, "3 cookies/bag" shows how there are three cookies per, or in each bag--which means 1 bag. The second unit, which is bag, has the quantity of one.

Answer:

16x=60

X=15/4

Step-by-step explanation:

Answer:

3

Step-by-step explanation:

We would be eliminating -9x from the equations.

Thus, we need to make the (-3x) into (-9x) in the first equation.

-9x ÷ -3x = 3

After that, you should be able to solve the equations:

-3x - 2y = 2

Equation 1×3: -9x - 6y = 6

-9x + 3y = 24

Answer:

Mark is 12 years old.

Step-by-step explanation:

Let's just define some variables:

J = Jason

A = Alex

M = Mark

Next, let's put the information given in the question into equations.

Since Jason is 10 years older than Alex we can represent it like this:

J = A + 10

Since Mark is 11 years younger than Alex we can represent it like this:

M = A - 11

All of their ages add up to 68 so we can represent that like this:

J + A + M = 68

We can now do some substitutions to the J and M in this equation, like this:

(A + 10) + A + (A - 11) = 68

Combine like terms:

3A - 1 = 68

Solve for A

3A = 69

A = 23

Now that we found that Alex is 23 we can plug that back in to the first equations to find their ages:

J = 23 + 10

J = 33

M = 23 - 11

M = 12

Mark is the youngest out of the siblings being 12 years old.

Check:

23 + 33 + 12 = 68

68 = 68 :)

I hope this helps!!

Answer:

Gabe worked for 6 2/3 hours and Paula worked for 4 hours.

Step-by-step explanation:

It is given that,

Diana worked on her science project for 5 1/3 hours.

Gabe worked on his science project 1 1/4 times as long as Diana.

Paula worked on her science project 3/4 as long as Diana.

Solution,

ATQ,

Gabe worked for :

[tex]5\dfrac{1}{3}\times 1\dfrac{1}{4}\\\\=\dfrac{16}{3}\times \dfrac{5}{4}\\\\=\dfrac{20}{3}\ h\\\\=6\dfrac{2}{3}\ h[/tex]

Pauls worked for :

[tex]\dfrac{3}{4}\times 5\dfrac{1}{3}\\\\=\dfrac{3}{4}\times \dfrac{16}{3}\\\\=4\ h[/tex]

Hence, Gabe worked for 6 2/3 hours and Paula worked for 4 hours.

Answer:

He bought 544 oranges and 1,360 apples

Step-by-step explanation:

Here, we want to know the number of oranges and apples bought

Let the number of oranges be x and the number of apples be y

Looking at their ratios;

x:y = 2:5

so;

x/y = 2/5

2y = 5x ••••••(i)

Now, he lost 3/4 of the apples ( by giving out)

What would be left with him is (1-3/4) = 1/4 * y = 0.25y

What is left with him out if the oranges will be; x-34

So now;

0.25y/x-34 = 2/3

3(0.25y) = 2(x-34) •••••••(ii)

From i, y = 5x/2 = 2.5x

Putting this into ii above, we have

3(0.25)(2.5x) = 2x - 68

1.875x = 2x-68

2x-1.875x = 68

0.125x = 68

x = 68/0.125

x = 544

But y = 2.5x

y = 2.5 * 544 = 1,360

Answer:

All the edges of a cube have the same length, and the volume of a cube is the length of an edge taken to the third power. So the length of the edge of a cube with a volume of 125 is 5.
