Answer: Alex spent 3 5/12hours studying on Sunday

Step-by-step explanation:

total hours spent studying in the weekend  =5 2/3 hour

Hours spent on saturday =2 2/8

Hours spent on sunday  =total hours spent studying in the weekend  - Hours spent on saturday=

=5 2/3 - 2 2/8

=3 16-6/24

=3 10/24

=3 5/12

Respuesta:

Aplicando la propiedad distributiva

Explicación paso a paso:

Sin resolver la operación contenida en el paréntesis, podríamos suprimir el paréntesis usando la propiedad distributiva, de modo que el factor fuera del paréntesis se use para multiplicar cada factor entre paréntesis:

(3 + 8). 2 + 6. (5 + 4)

Sin tener que ocuparnos de la operación de suma entre paréntesis, podemos extraer ambos valores mediante

2 * 3 + 2 * 8 + 6 * 5 + 6 * 4

6 + 16 + 30 + 24

= 76

Answer:

−6

Step-by-step explanation:

3(−6+4)

=(3)(−2)

= −6

Hope this helps :)

Do the Brackets

-6+4=-2

Now multiply 3 and -2

3*-2=-6

You have your answer

-6

Answer:

m<N = 32°

m(NQ) = 106°

Step-by-step explanation:

Inscribed angle = ½ of the measure of the intercepted arc (inscribed angle theorem)

<N is an inscribed angle

It's intercepted arc = arc MP = 64°

Therefore,

m<N = ½(64°)

m<N = 32°

m<P = ½(m(NQ)) (inscribed angle theorem)

53° = ½(m(NQ))

Multiply both sides by 2

2*53° = m(NQ)

106° = m(NQ)

m(NQ) = 106°

Answer: Warsaw

Step-by-step explanation:

Warsaw is the capital and largest city of Poland. It is located on the Vistula River, in east-central Poland, roughly 260 kilometres from the Baltic Sea and 300 kilometres from the Carpathian Mountains.

Answer:Answer:

13.0feet

Step-by-step explanation:

Given ΔDEF with ∠F=90°, the measure of ∠D=19°, and DE = 40 feet, since one of the angles of the triangle is 90°, the triangle is a right angled triangle as shown in the attachment.

Using SOH, CAH, TOA to get the unknown EF.

Since <D is opposite to side EF, EF will be the opposite while side DE will be the hypotenuse

Based on SOH:

Sin<D = Opposite/Hypotenuse

Sin<D = EF/DE

Sin19° = EF/40

EF = 40sin19°

EF = 13.0 feet to the nearest tenth of a foot

Answer:

2)  26 p^6 h^4

3) 18 x^2 y^5 z^7

4)  -20 c^4  

is correct answer.

i guess you dont know this '' ^ '' . this mean take that number in power,

All the best

Step-by-step explanation:

Answer: A) Yes, it is a solution.

=================================================

Explanation:

Replace every x with -3 and simplify both sides.

3x - 2 < 2 - 2x

3(-3) - 2 < 2 - 2(-3)

-9 - 2 < 2 + 6

-11 < 8

Since -11 is to the left of 8 on the number line, this means the inequality -11 < 8 is true. Consequently, it means the first inequality is true when x = -3.

Therefore, x = -3 is a solution.

Answer:

a= 3

Step-by-step explanation:

Answer:

x=5 30 degrees

Step-by-step explanation:

theres 90 degrees in the right angle and you already have 60 degrees so you know it has to equal to 90 degrees so it has to be 30 degrees and 6 x 5 is equal to 30

Answer:

6

Step-by-step explanation:

3n = n + 12

2n = 12

n = 6

Answer:

6

Step-by-step explanation:

let the number be x , then

3x = x + 12 ( subtract x from both sides )

2x = 12 ( divide both sides by 2 )

x = 6

That is the number is 6

Hey there I just saw no one answered this problem and I know this is a little late but I will answer it anyways.

Answer: The answer to this problem would be points A and B

Answer:

B

Step-by-step explanation:

We can determine the total miles run by the 10 students by adding all the miles run by each individual student:

A

1 student * 1/12 miles = 1/12 miles

2 students * 1/8 miles = 2/8 miles = 1/4 miles

1 student * 1/6 miles = 1/6 miles

2 students * 1/4 miles = 2/4 miles = 1/2 miles

1 student * 1/3 miles = 1/3 miles

3 students * 1/2 miles = 3/2 miles

We add all these fractions to obtain 17/6, which is approximately 2.83, which is not as the question describes.

B

2 students * 1/6 miles = 1/3 miles

2 students * 1/4 miles = 1/2 miles

2 students * 1/3 miles = 2/3 miles

3 students * 1/2 miles = 3/2 miles

1 student * 1 mile = 1 mile

We add all these fractions to obtain 4 miles, which is as the question describes.

Answer:

The total weight of the grass seed is [tex]\frac{33}{8}[/tex] pounds

Step-by-step explanation:

Given

Total bags of seeds [tex]= 5\frac{1}{2}[/tex]

Weight of each bag [tex]= \frac{3}{4}[/tex] Pounds

Total weight of the grass seed  = Total number of bags of seeds * Weight of each bag

Total weight of the grass seed  =

[tex]5\frac{1}{2} *\frac{3}{4} \\=\frac{11}{2}*\frac{3}{4}\\=\frac{33}{8}[/tex]Pounds

The total weight of the grass seed is [tex]\frac{33}{8}[/tex] pounds

Answer:

33/8= 4 1/8 so its B.

Step-by-step explanation:

Answer:

cos θ = [tex]\frac{\sqrt{11} }{6}[/tex]

Step-by-step explanation:

Substitute sin θ = [tex]\frac{5}{6}[/tex] into the identity

( [tex]\frac{5}{6}[/tex] )² + (cos θ )² = 1

[tex]\frac{25}{36}[/tex] + (cos θ )² = 1

(cos θ )² = 1 - [tex]\frac{25}{36}[/tex] = [tex]\frac{11}{36}[/tex] ( take the square root of both sides )

cos θ = [tex]\sqrt{\frac{11}{36} }[/tex] = [tex]\frac{\sqrt{11} }{6}[/tex]

Answer:

y =  2*x^2 - 2*x - 24

Step-by-step explanation:

If we have a quadratic function with roots a and b, we can write the equation for that function as:

y = f(x) = A*(x - a)*(x - b)

Where A is the leading coefficient.

In this case, we know that the roots are: 4 and -3

Then the function will be something like:

f(x) = A*(x - 4)*(x - (-3) )

f(x) = A*(x - 4)*(x + 3)

Now we need to determine the value of A.

We also know that the graph of the function passes through the point (3, -12)

This means that:

f(3) = -12

Then:

-12 = A*(3 - 4)*(3 + 3)

-12 = A*(-1)*(6)

-12 = A*(-6)

-12/-6 = A

2 = A

Then the equation is:

y = f(x) = 2*(x - 4)*(x + 3)

Now we need to write this in standard form, so we just need to expand the equation:

y = f(x) = 2*(x^2 + x*3 - x*4 - 4*3)

y = f(x) = 2*(x^2 - x - 12)

y = f(x) = 2*x^2 - 2*x - 24

Then the relation is:

y =  2*x^2 - 2*x - 24

Answer:

100÷(20÷5)

Step-by-step explanation:

first find out how many chairs each worker made

20÷5=4

then divide 100 by 4 and that will give you 25

they would need 25 workers the equation that they should use is
