Answer:

7744

Step-by-step explanation:

Din informațiile furnizate:

Succesorul primului număr 999 = 1000

Al doilea este cu 1872 mai mare= 1872 + 1000 = 2872

Al treilea care sunt primele două împreună = 1000 + 2872 = 3872

∴

Suma celor trei numere = 1000 + 2872 + 3872

= 7744

Answer:

x=4

Step-by-step explanation:

7/9 - x/9 = 1/3

I like to get rid of fractions so I will multiply each side by 9

9*(7/9 - x/9) = 1/3*9

7 - x = 3

Subtract 7 from each side

7-x-7 = 3-7

-x= -4

Multiply each side by -1

x =4

Answer:

70 students

Step-by-step explanation:

As, 30% Mike surveyed

And these 30% are 21 students

So 30% of X = 21

= 30/100 x X = 21

= 30X = 2100

So X = 2100/30

X = 70

So 70 students were surveyed

There are 70 students did Mikey survey.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

We have to given that;

Of all the students that Mikey surveyed, 30% said they play baseball.

And, There are 21 students play baseball.

Now, Let number of students did Mikey survey = x

So, We can formulate;

⇒ 30% of x = 21

Solve for x;

⇒ 30/100 × x = 21

⇒ 30x = 2100

⇒ x = 70

Thus, The number of students did Mikey survey = 70

Answer: $35,242.79 given the formula

Answer:

Length = 3

Step-by-step explanation:

the formula for area of a rectangle is Area = Base (width) x Height (length)

so plug in out values: 3/2 = 1/2 x H

divide both sides by 1/2 to find the height/length: 3/2 ÷ 1/2 = Height

to divide a fraction by a fraction, flip the divisor and change the sign from ÷ to ×

so you get 3/2 × 2/1 = Height

the 2 cancels out, so you get: 3 = height/length

Answer: (2,-1)

Step-by-step explanation: I learned this earlier in the year

Answer:

Step-by-step explanation:

A is correct.

2/3 > 4/8

5/9 > 7/12    This one is close. They are both nearly 1/2, but 9<12 and when you divide something by 9 the remainder is going to be larger than if you divide by 12.

The second one is incorrect.

3/4 > 5/9    5/9 is close to 1/2. Three quarters is much greater than 1/2

3/10 is much smaller than 5/9

The third one is correct. 1/10 and 5/6 are much larger than the two fractions on the right. The right side = 56/60 which is very nearly one. The left side is nowhere near that large. (I did estimate the right side).

The fourth one is correct. 9/10 is much larger than 2/3 and 5/9 is larger than 5/12. 5/9 is over 1/2 and 5/12 is under one half. So the arrow in the fourth one is going the right way.

Answer:

Step-by-step explanation:

45% = [tex]\frac{45}{100}[/tex]

No. of T-shirts size medium = [tex]\frac{45}{100}[/tex] × 80

                                              = 36

The value of [tex]Cos(A - B)[/tex] will be [tex](\frac{-\sqrt{5} }{5} )[/tex].

Trigonometric functions are  the periodic functions which denote the relationship between angle and sides of a right-angled triangle.

We have,

[tex]Sin(A) = \frac{4}{5}[/tex] ,    [tex]\frac{\pi }{2} < A < \pi[/tex]

[tex]Sin(B) = \frac{-2\sqrt{5} }{5}[/tex] ,   [tex]\pi < B < \frac{3\pi }{2}[/tex]

So,

Using identity ;

[tex]Cos(A - B)= CosA\ *\ Cos B + Sin A\ *\ Sin B[/tex]

So,

First find [tex]SinB[/tex] and [tex]CosA[/tex];

i.e.

[tex]CosB=\frac{-\sqrt{5} }{5}=\frac{-1}{\sqrt{5} }[/tex],   [tex]\pi < B > \frac{3\pi }{2}[/tex]

[tex]CosA=\frac{-3}{5}[/tex],    [tex]\frac{\pi }{2} < A > \pi[/tex]

Now,

Substituting values,

[tex]Cos(A - B)= CosA\ *\ Cos B + Sin A\ *\ Sin B[/tex]

[tex]Cos(A - B)= ((\frac{-3}{5})\ *\ \frac{-1}{\sqrt{5}} ) +((\frac{4}{5})\ *\ \frac{-2\sqrt{5} }{5} )[/tex]

Simplify,

[tex]Cos(A - B)= (\frac{3 }{5\sqrt{5}} ) -(\frac{8 }{5\sqrt{5}})[/tex]

[tex]Cos(A - B)= (\frac{-5 }{5\sqrt{5}} )[/tex]

[tex]Cos(A - B)= (\frac{-1 }{\sqrt{5}} )[/tex]

Or we can write

[tex]Cos(A - B)= (\frac{-\sqrt{5} }{5} )[/tex]

Hence, we can say that the value of [tex]Cos(A - B)[/tex] will be [tex](\frac{-\sqrt{5} }{5} )[/tex] which is given in option (b).

Answer:

The equation in the point-slope form will be:

Step-by-step explanation:

Given

Using the point-slope form of line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

here

substituting the values m = 2/3 and the point (-3, 5)  in the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-5=\frac{2}{3}\left(x-\left(-3\right)\right)[/tex]

Thus,  the equation in the point-slope form will be:

[tex]y-5=\frac{2}{3}\left(x-\left(-3\right)\right)[/tex]

NOTE: The equation in the point-slope can be further simplified such as:

[tex]y-5=\frac{2}{3}\left(x-\left(-3\right)\right)[/tex]

[tex]y-5=\frac{2}{3}\left(x+3\right)[/tex]

Add 5 to both sides

[tex]y-5+5=\frac{2}{3}\left(x+3\right)+5[/tex]

[tex]y=\frac{2}{3}x+7[/tex]
