Answer:

43.71428571

Step-by-step explanation:

First, convert 7 2/7 into an improper fraction: 51/7

Second, multiply 51/7 by 5: 255/7

Third, add 255/7 and 51/7 to get 306/7

306/7 = 43.71428571

Answer:

x = 3.6

B. {7.88}

Step-by-step explanation:

[tex]\frac{6}{x}= \frac{10}{6}[/tex]

x · 10 = 6 · 6

10x = 36

10x ÷ 10 = 36 ÷ 10

x = 3.6

[tex]\frac{9}{8} =\frac{x}{7}[/tex]

8 · x = 9 · 7

8x = 63

8x ÷ 8 = 63 ÷ 8

[tex]x=7\frac{7}{8}[/tex] or x = 7.875

7.875 rounded to the nearest tenth is 7.88.

Step-by-step explanation:

Answer:

A.

Step-by-step explanation:

Take a look at what happens when squaring either of these...

[tex](ax-by)^2=(ax-by)(ax-by)=a^2x^2-2abxy+b^2y^2\\\\(ax+by)^2=(ax+by)(ax+by)=a^2x^2+2abxy+b^2y^2\\[/tex]

Notice a couple of patterns.

1.  The last term has a positive coefficient.  That rules out answer choices C and D.

2.  The coefficient of the middle term is either [tex]+2ab \text{ or } -2ab[/tex] .  So what are a  and b?  a is the square root of the x^2 term and b is the square root of the y^2 term.

[tex]25x^2 \Rightarrow a=5\\\\9y^2 \Rightarrow b=3\\\\ab=15\\\\2ab=30[/tex]

The middle coefficient needs to be either +30 or -30.  The answer is choice A.

7 kittens didn't finish their milk

Step-by-step explanation:

4/5 of 35 = 28

35-28=7

can i have brainlist pls

Answer:

7 kittens

Step-by-step explanation:

[tex]\frac{4}{5}=\frac{y}{35}[/tex]

5 · y = 4 · 35

5y = 140

5y ÷ 5 = 140 ÷ 5

y = 28

35 - 28 = 7

Answer:  I believe the correct answer from the choices listed above is the third option. The base shape of a cylinder would be circle. A cylinder is a closed solid that has two parallel (usually circular) bases connected by a curved surface.

Hope this answers the question. Have a nice day.

The base shape of the cylinder is a circle, the correct option is D.

A cylinder is a three dimensional figure made up of parallel circular discs.

The best shape of the base of a cylinder can be a circle only.

The cylinder has two circular bases as the surface joining the two bases is curved and has the same radius as the base.

Answer: it’s A

Step-by-step explanation:

I just took the test

The graph of f(x) is shown by figure A.

We have given that the  function,

[tex]f(x)=log_2x[/tex]

We have to determine the graph ofthe given function

We have to find the co-ordinate of the given finction

We have to put one variable value that is any real number and by using this value find the value of another variable.

[tex]y=f(x)=log_2x[/tex]

[tex]y=log_2x[/tex]

Put x=1

[tex]y=log_2(1)\\y=0[/tex]

We get the point A(1,0)

put x=2

[tex]y=log_2(2)\\y=1[/tex]

We get the point B(2,1)

Put x=4

[tex]y=log_2(4)\\y=2[/tex]

We get the point C(4,2)

So we plot this point on coordinate system so we get the graph

as shown below

Therefore  the option  A is correct.
