What is the value of 15 + x2 when the value of x is 3? also there's a tiny 2 above the 15

Answer:

3(2+5)−5(3)+8=14

Step-by-step explanation:

Write the problem as a mathematical expression.

=>3(2+5)−5⋅3+8

Simplify each term.

=>21−15+8 = 14

Answer:

149

Step-by-step explanation:

12× 24 = 288

228 - 139 = 149

Answer:

B. 149

Step-by-step explanation:

If the students have already filled 139 balloons with air and are going to use all the bags. They would need to fill 149 more balloons.

The first step would be to find the total number of ballons by calculating 12x24 which will give you 288.

From here you would need to subtract the number of ballons that are already filled with air from the balloons that remain which would be 288-139. This would give you a total of 149 balloons that still need to be inflated.

Answer:

      +27   +27

9x = 27

divide both sides by 9

x = 3

Answer:

Criag has 4 dimes and 8 nickles

Step-by-step explanation:

1 dime = 10 cents

1 nickle = 5 cents

4 dimes = 40 cents

8 nickles = 40 cents

40 cents + 40 cents = 80 cents

8 - 4 = 4

therefore it is equivelent that criag has 4 dimes and 8 nickels.

Answer:

D

Step-by-step explanation:

I would say D because youre trying to find red and blue so green and brown dont matter to the problem. If 12÷6= 2 then. do 60÷2=30 so they can be drawn about 30 times

Answer:

55 special dinners

Step-by-step explanation:

From the question,

Last month rudys tacos sold 22 dinner specials.

The next month they sold 250% of last months dinners.

Hence:

250% × 22 special dinners

= 55 special dinners

The number of dinner specials they sold this month is 55 special dinners

Answer:

[tex]x=42[/tex]

Step-by-step explanation:

Use this to remember the trigonometry ratios:

SOH-CAH-TOA

Because:

Sine=Opposite/Hypotenuse → SOH

Cosine=Adjacent/Hypotenuse → CAH

Tangent=Opposite/Adjacent → TOA

Use the inverse of the tangent ratio since you need to find the angle measure.

Answer:

Step-by-step explanation:

Depends on the tree.

If it's like a pine or spruce, then I would use maybe 2 inches lattitude. If it's really leafy with big leaves, perhaps a little more lattitude is needed, like maybe 1/2 a foot.

It also depends on the season. Unless the pine or spruce is covered with snow, I wouldn't change the latitude. If it is covered with snow, knock the snow off.

For something like a maple in winter, I'd reduce the latitude to 3 inches......

Answer:

10.5

Step-by-step explanation:

Both widths are the same in a rectangle. So both are 6.5. Then you subtract 13 from 34. Now you are left with 21. No divide that by two to get your two lengths. That is l. L=10.5

Answer:

Step-by-step explanation:

P=2L+2W

P=34        W= 6.5

34=2L+2*6.5

34=2L+13

2L=21

L=10.5

or

Given:

P = 34 [Perimeter]

W = 6.5 {let's use W and L to make it easy to read]

Also known:

P = W + L + W + L = 2(W+L)

Fill in values:

34 = 2(6.5+L) [NOTE: This is an equation to determine the length (L) of the rectangle."]

. . .

17 = 6.5 + L [NOTE: This is a simplified form of the above equation.]

. . .

10.5 = L [NOTE: This is the solution (the value of L)]

Answer:

Dimension = 6 feet × 3 feet

Step-by-step explanation:

From the question given above, the following data were obtained:

Length (L) = 6 feet

Distance around the fence (Perimeter) = 18 feet

Dimension of the fence =?

Next, we shall determine the breadth of the rectangular fence. This can be obtained as follow:

Length (L) = 6 feet

Perimeter (P) = 18 feet

Breadth (B) =?

Perimeter of rectangle is given by:

P = 2(L + B)

18 = 2 (6 + B)

Clear the bracket

18 = 12 + 2B

Collect like terms

18 – 12 = 2B

6 = 2B

Divide both side by 2

B = 6/2

B = 3

Thus, the breadth of the rectangular fence is 3 feet

Dimension of the rectangular fence is given by:

Dimension = length × Breadth

Length (L) = 6 feet

Breadth (B) = 3 feet

Dimension = 6 feet × 3 feet

Answer:

Real distance between Manchester and London = 263.2 km

Step-by-step explanation:

Given that:

A map has a scale of 1 cm = 14 km

Ratio = 1 : 14

Distance from Manchester to London = 18.8 cm

Let,

x be the real distance between Manchester and London.

Ratio = 18.8 : x

As the relationship is proportional,

1 : 14 :: 18.8 : x

Product of mean = Product of extreme

14*18.8 = x

x = 263.2 kilometers

Hence,

Real distance between Manchester and London = 263.2 km

Answer:

46

Step-by-step explanation:

AC = 2FD

CE = 2BF

AE = 2BD

2FD + 2BF + 2BD = 2(FD + BF + BD) = AC + CE + AE

2[tex]P_{FBD}[/tex] = [tex]P_{ACE}[/tex] ⇒ [tex]P_{FBD}[/tex] = [tex]\frac{1}{2}[/tex] [tex]P_{ACE}[/tex]

Answer:

141

Step-by-step explanation:

This is a seven-sided pentagon. We can find the total sum of all the angles in the pentagon first.

Sum of angles in a pentagon = (7-2) × 180

                                                = 5 × 180

                                                = 900

∠B = 900 - 148 - 90 - 142 - 130 - 129 - 120

     = 141

Remember:

Formula of sum of angles in pentagon = (n-2) × 180 where n is the number of sides the pentagon has. Hope this helps :)

Answer:

Yes

Step-by-step explanation:

a^2+b^2=c^2

7^2+11^2=c^2

49+121=c^2

170=c^2

then square it

c=13

7,11,13 is a pythagorean triple

Answer:

both answers you have put in are correct

Step-by-step explanation:

7^2=49

11^2=121

121+49=170

square root of 170 is the long side

not a pythagorean triple because square root of 170 does not come out as a whole number (no decimal/fraction)

is it ~13.0384

Hey there!

The answer to your question is Crew A

We can find this by first finding the unit rate, or acres per hour. We can divide the amount of acres by the amount of hours.

Crew A : 6/7.5 = 0.8 acres per hour

Crew B : 4.5/6 = 0.75 acres per hour

With the data above, we can see that Crew A is faster.
