Answer:

47

Step-by-step explanation:

First you do the exponent

2 times 2 times 2 is 8

then multiply 8 times 5 is forty

forty plus 7 is forty seven.

Hope this helps!

Step-by-step explanation:

2 with an exponent of 3 is 8

5x8=40

40+7=47

Answer:

Answer:

b = c/a

Step-by-step explanation:

simply make b the subject.

a=3

a6=43

a+6d=43---------1

substituting a=3 in eq 1

a+6d=43

3+6d=43

6d=43-3

d=40/6

d=20/3

so first 5 no's are a, a+d, a2+d,a3+d, a4+d

a=3

a+d=3+20/d

i think u know after this

Hope it helps u

mark me as brainest if it helps u

Answer:

3,11,19,27,35

Step-by-step explanation:

an=a1+(n-1)d

a1=3 (given)

a6=43

d=?

a6= a1+(6-1)d

43= 3 + 5d

d= 8

first number a1=3

a2= a1+d

a2= 3+8=11

a3= a1+2d

= 3+2(8)=19

a4= a1+3d

= 3+3(8)=27

a5=a1+4d

=3+4(8)=35

Answer:

Infinite solutions

Step-by-step explanation:

Simplify both sides, subtract 9x, and add 21x to both sides and you will get 0 = 0 so there is infinite solutions.

Answer:

y=2/(x−7)

Step-by-step explanation:

To find the inverse function, swap x and y, and solve the resulting equation for x. If the initial function is not one-to-one, then there will be more than one inverse. So, swap the variables: x=7+(2/y) for y. y=2/(x-7).

Answer:

C

Step-by-step explanation:

Because if you multiply a number by 2 instead of it self like 3x2 instead of 3x3

you would get a multiple of 2 not its square

Answer: a+b+c+ 1 /4 d

Step-by-step explanation:

Answer:

Domain: [tex]t \geq 0[/tex]

Range: [tex]v \geq 550[/tex]

Step-by-step explanation:

Given

[tex]v = 550 + 16.5t[/tex]

Required

Determine the domain and the range

Solving for domain:

From the question, we understand that t represent years.

Because years can't be negative;

Then, we can conclude that the domain, t is:

[tex]t \geq 0[/tex]

Solving for Range:

We solved domain to be [tex]t \geq 0[/tex]

This implies that the minimum value of t is [tex]t = 0[/tex] and the maximum is infinity

Substitute 0 for t in [tex]v = 550 + 16.5t[/tex]

[tex]v = 550 + 16.5(0)[/tex]

[tex]v = 550 + 0[/tex]

[tex]v = 550[/tex]

Hence;

The range is [tex]v \geq 550[/tex]

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{9.69 \: cm}}}}}[/tex]

Step-by-step explanation:

Area of a square ( A ) = 94 cm²

Length of a square ( L ) = ?

Finding the length of a square

[tex] \boxed{ \sf{area \: of \: a \: square = {l}^{2} }}[/tex]

[tex] \longrightarrow{ \sf{94 = {l}^{2} }}[/tex]

[tex] \longrightarrow{ \sf{ {l}^{2} = 94}}[/tex]

[tex] \longrightarrow{ \sf{ \sqrt{ {l}^{2} } = \sqrt{94}}} [/tex]

[tex] \longrightarrow{ \sf{l = 9.69 \: cm}}[/tex]

Hope I helped!

Best regards! :D

Answer:

10 is the answer

Answer:

I believe it would be the third option. x=20.

Step-by-step explanation:

the 2 over the x cancels out the square root over the 20.

Answer:

x=50  

Step-by-step explanation:

angle 1 and 3 are corresponding angles that menas they equal the same

so set it up like this 2x+10=110 solve for x

move over the 10, subtract 10 from 110 you get 100 and divide by 2

you get 50.

Answer:

Consumption of gas = 8.5 gallon (Approx)

Step-by-step explanation:

Given:

Distance from mall = 108.7 miles

Average of car = 25.6 mpg

Find:

Consumption of gas

Computation:

Total distance covers = 2(108.7)

Total distance covers = 217.4 miles

Consumption of gas = 217.4 / 25.6

Consumption of gas = 8.4921

Consumption of gas = 8.5 gallon (Approx)

Answer:

9

Step-by-step explanation:

because you know the areais 33.3 so divide 33.3by7.4 and  that gives you 4.5 and then multiply 4.5 times 7.4 to give you 33.3 BUT you know you have to divide by 2 to  get the area of a triangle so multiply 4.5 times 2 to get you 9.  

So 9 times 7.4=66.6/2=33.3

Answer=9

Answer:

∠4=135

Step-by-step explanation:

vertical angles are always equal

∠1=∠3

3x-9=x+27

3x-x=27+9

2x=36

x=36/2=18

∠1 =3x-9

∠1=3(18)-9

∠1=54-9=45

∠1+∠4=180 degrees

45+∠4=180

∠4=180-45

∠4=135

Answer:

Multiply the numbers until you get the same denominator (Bottom number) for both fractions. I will do #1 to show you.

1/3    1/2

Both 3 and 2 go into 6, so I will use that.

When multiplying the bottom , you have to do the same to the top, so...

2/6  OR  3/6

3/6 is greater, so that is the answer.

Therefore, 1/2 is more

Another way you can do this is to draw a pizza, a section off parts of it according to the fractions.

Hope this helped.

Answer:

a. 1/2

b. 5/6

c. 4/9

d. 12/5

e. 2/9

f. 2/5

Step-by-step explanation:

a. 1/3 < 1/2

1(2)= 2. 3(2)= 6. 1/6

1(3)= 3. 2(3)=6.  3/6  

b. 4/5 < 5/6

4(6)= 24. 5(6)= 30. 24/30

5(5)= 25. 6(5)= 30. 25/30

c. 3/8 < 4/9

3(9)= 27. 8(9)= 72. 27/72

4(8)= 32. 9(8)= 72. 32/72

d. 12/5 > 9/4

12(4)= 48. 5(4)= 20. 48/20

9(5)= 45.  4(5)= 20. 45/20

e. 1/5 < 2/9

1(9)= 9.  5(9)= 45. 9/45

2(5)= 10. 9(5)=45. 10/45

f. 2/5 > 3/9

2(9)= 18.  5(9)= 45.  18/45

3(5)= 15.  9(5)= 45.  15/45

Answer:

4.69 inches (2 decimal places)

Step-by-step explanation:

Refer to image attached to this answer:

Using Pythagoras Theorem:

[tex]AB^2+AC^2=BC^2[/tex]

[tex]2^2+3^2=BC^2[/tex]

[tex]4+9=BC^2[/tex]

[tex]BC^2=13[/tex]

-------------------------

Using Pythagoras Theorem,

[tex]BC^2+CD^2=BD^2\ (x)[/tex]

[tex]13+3^2=BD^2[/tex]

[tex]13+9=BD^2[/tex]

[tex]BD=\sqrt{22} = 4.69\ (2d.p.)[/tex]

First, we have to find the last remaining side of the leftmost triangle.

We can use the Pythagorean theorem.

The Pythagorean theorem: a^2 + b^2 = c^2

a = one leg

b = the second leg

c = the hypotenuse

In this problem,

a = 3

b = 2

c = ?

Let's plug our numbers into the Pythagorean theorem.

3^2 + 2^2 = c^2

Simplify the left side

9 + 4 = c^2

Add together like terms

13 = c^2

Take the square root of both sides

[tex]\sqrt{13}[/tex] = c

Now we can use the Pythagorean theorem on the rightmost triangle to find x.

a = 3

b = [tex]\sqrt{13}[/tex]

c = x

let's plug our values into the Pythagorean theorem.

3^2 + ([tex]\sqrt{13}[/tex])^2 = (x)^2

Simplify the left side

9 + 13 = x^2

Add together like terms

22 = x^2

Take the square root of both sides

[tex]\sqrt{22}[/tex] = x

But the problem is asking for the approximate value, the approximate value of [tex]\sqrt{22}[/tex] = 4.69 in

Answer:

8

Step-by-step explanation:

mary = twice older than zane

zane=four yrs less than twice of chase

chase= 4

therefore;

twice of chase is  8 and zane is 4 years less so

8-4=4

and mary is twice older so
