Answer:

C

Step-by-step explanation:

The question states he wants to show the relationship between the trees ages and the number of apples they produce.

Answer:

B

Step-by-step explanation:

Answer:

1. y=5 and x=-5

2. y=2 and x=-4

Step-by-step explanation:

1.y=-5x-19

y=-6x-24

since both equations are equal to y, they are also equal to eachother

-5x-19=-6x-24

addition P.O.E.

x-19=-24

addition P.O.E.

x=-5

substitute x into one equation

y=-5*-5-19

y=6

2. y=-6x-22

y=-3x-10

since both equations are equal to y, they are also equal to eachother

-6x-22=-3x-10

addition P.O.E.

-22=3x-10

addition P.O.E.

-12=3x

division P.O.E.

-4=x

substitute x into one equation

y=-3*-4-10

y=2

Answer:

A

Step-by-step explanation:

B is wrong because 5^2 = 25

C is wrong because 5 is not equal to √5

D is wrong because 25 is not √5 but 5^2

Answer:

70.06

Mean score = 70

Step-by-step explanation:

16% of students scored higher than 80 on a recent normally distributed exam the standard deviation is 10 what is the mean

For a normal distribution :

Zscore = (x - mean) / standard deviation

x = score

P(Z > 80) = 16% = 0.16 ; corresponding Zscore = 0.994 (Z probability calculator)

Therefore ;

0.994 = (80 - mean) / 10

0.994 * 10 = 80 - mean

9.94 = 80 - mean

Mean = 80 - 9.94

Mean = 70.06

Hence, the mean score = 70.06 = 70

Answer:

the product of 32.56 and 1.4 = 45.584

Step-by-step explanation:

When you multiply decimals, the decimal point is placed in the product so that the number of decimal places in the product is the sum of the decimal places in the factors.

hope i helped:)

Answer:

Your answer would be 32.56

Step-by-step explanation:

We know that when you multiply decimals the number decimals placed is the product or sum of the decimals placed in there own factors.

my dad helped with this hope it helps you

Answer:

Step-by-step explanation:

In a pen there are 200 animals,

25 of which are ducks,

Number of turkeys

50% are turkeys

= 50% × 200

= 100 turkeys

and

Numbers of chickens

75% are chickens.

= 75% × 200

= 150

How many animals are ducks, turkeys and chickens?

Step-by-step explanation:

Answer:

x = 66

Step-by-step explanation:

All triangle angles add up to 180 so:

x + 79 + 35 = 180

x + 114 = 180

x = 180 - 114

x = 66

Answer:

66°

Step-by-step explanation:

Since the sum off all the angles of a triangle is 180°,

x + 79° + 35° = 180°

x + 114° = 180°

x = 180° - 114° = 66°

Therefore, x = 66°

Answer:

Step-by-step explanation:

(h + 6) - 2    Here we find the sum of h and 6, and from that sum we subtract 2.

This simplifies to h + 4.

Answer:

h+4

Step-by-step explanation:

h+6-2=h+4

Answer:

-10, square root of 100, square rout of 220, 11.5

Step-by-step explanation:

Answer:

B. 13

Step-by-step explanation:

Let's solve your equation step-by-step.

7√x−4−6=15

Step 1: Add 6 to both sides.

7√x−4−6+6=15+6

7√x−4=21

Step 2: Divide both sides by 7.

7√x−4

7

=

21

7

√x−4=3

Step 3: Solve Square Root.

√x−4=3

x−4=32(Square both sides)

x−4=9

x−4+4=9+4(Add 4 to both sides)

x=13

Answer:

x = 13

Step-by-step explanation:

[tex]7 \sqrt{x - 4} = 15 + 6 \\ 7 \sqrt{x - 4} = 21 \\ \sqrt{x - 4 =} = 3 \\ x - 4 = 9 \\ x = 13[/tex]

Answer:

-24

Step-by-step explanation:

i dont think this is right answer

hope this helps via substitution process

Answer:

4 + 4 + 2 = 10

3) 3/10 or 0.3

4) 2/10 = 1/5 or 0.2

5) 4/10 = 2/5 or 0.4

6) 2 + 4 + 0 = 6 so 6/10 = 3/5 or 0.6

Answer:

The equation is

2.7x - 5.4

Step-by-step explanation:

Gas is priced at $2.70 per gallon. My gas tank has 2 gallons currently in the tank. Write an equation to how much

the money I will spend to fill up my tank.

Let the total gallons that would fill your tank = x

The tank currently has 2 gallons

A gallon =>$2.70

Therefore, our equation is

=(x - 2) × 2.70

= 2.7x - 5.4

Answer: 37/12

Step-by-step explanation: First you must turn 2 1/6 into a improper fraction, so 2x6 + 1 will get you 13 as the numerator and the denominator will be 6 so now we have 13/6 + 11/12. Now we must turn the denominator for 13/6 into 12 so, 13x2/6x2 so it is 26/12 so now the equation is 26/12 + 11/12 is 37/12.

Answer: 803.84 inch²

Step-by-step explanation:

The lid will take the appearance of a circle so the area of the lid is the same as the area of a circle:

Area of a circle = π * radius²

The circumference of a circle is:

= π * diameter

Looking at the above, the diameter is 32inches because this is the figure to be multiplied with π = 3.14 to find the circumference.

Since diameter is 32, radius will be:

= 32 / 2

= 16 inches

Area = 3.14 * 16 * 16

= 803.84 inch²

Answer:

st=22

m<r=68

m<t=22

Step-by-step explanation:

Side rt = 24

Side sr = 9

Side st = 22.2486

Angle ∠s = 90° = 1.5708 rad = π/2

Angle ∠t = 22.024° = 22°1'28" = 0.3844 rad

Angle ∠r = 67.976° = 67°58'32" = 1.1864 rad

Answer:

100:60:80

Step-by-step explanation:

240÷12=20

20×5=100

20×3=60

20×4=80

Answer:

100: 60: 80

Step-by-step explanation:

5/(5+3+4) *240= 100

3/(5+3+4)* 240= 60

4/(5+3+4)* 240= 80

Answer:

86.6666666667

Step-by-step explanation:

Because one of Tom's car wheel weighs 21 2/3 pounds, you would have to multiply 21 2/3 pounds by 4 to get the amount of pounds that all the tires weigh; which makes the answer:86.6666666667

Answer:

86 2/3

Step-by-step explanation:

you multiply 21 × 4 and get 84

multiply 2 × 4 and get 8

Divide 8/3 and get 2 2/3

add 2 to 84

and leave the 2/3
