Answer:

i would say... maybe a or  c

Step-by-step explanation:

im not sure

Answer:

It is rational because 121 is a perfect square.

Answer:

Yes they would be because 2^2 or 2x2 =4 and -2^2 or -2x-2 also equals four because a neg x a neg equals a pos

Step-by-step explanation:

A I believe because Against the odds of 38/50 would be 12/50 that is not an option so split in half this would be A cause its an equivalent fraction

Answer:

The oil needed is 0.51.

Step-by-step explanation:

Since you know that the gas to oil ratio is 50:1 and you have to find the oil needed for 25.5L of gas, you can write the numbers in the ratio as a fraction and let's consider that x is the amount of oil needed:

[tex]\frac{50}{1} = \frac{25.5}{x}[/tex]

Now, you have to solve this using cross multiplication:

50*x=25.5*1

50x=25.5

Finally, your have to isolate the variable x:

x=25.5/50

x=0.51

According to this, the answer is that the oil needed is 0.51.

Answer:

J

Step-by-step explanation:

Area of a square = L x W

F:

(5 x 5) + (4 x 4) = 81

25 + 16 = 81

41 = 81  INCORRECT =( X

H:

64 + (5 x 5) = (13 x 13)

64 + 25 = 169

89 = 169 INCORRECT =( X

G:

(6 x 6) + (5 x 5) = (7 x 7)

36 + 25 = 49

61 = 49 INCORRECT =( X

J:

144 + (5 x 5) = 169

144 + 25 = 169

169 = 169  CORRECT =)

x < 2

Step-by-step explanation:

I didnt feel like typing it out but the explanation is in the picture hope this helps :)

Answer:

x<2

x/2 plus 3/2 <less than or equal to 5/2

x/2< 2/2 or 1

X < 2 * 1

X < 2

have a great day!!!

Answer:

x = - 4

[tex]g(x) = 8 {x}^{2} + 4x[/tex]

g(- 4) =?

[tex]g( - 4) = 8( { - 4)}^{2} + 4( - 4) \\ g( - 4) = 8 \times 16 - 16 \\ g( - 4) = 128 - 16 \\ g( - 4) = 112[/tex]

=> g (- 4) = 112.

Answer:

7

Step-by-step explanation:

4 : 3

8 : 7

Answer:

if I'm right, you are trying to find the area of the parallelogram. if you are trying to find the area, then based on the information provided, you need to add the purple side (9.2 cm) with the grey side (2 cm) which gives you 11.2 cm. then you would multiply this answer by the blue line (7 cm) giving you 78.4 cm. finally, you divide this by 2 giving you 39.2 cm. I'm not sure if this was what you were looking for, but I hope this helps either way.

Step-by-step explanation:

(9.2 + 2) x 7/2

11.2 x 7/2

78.4/2 = 39.2

Answer:3.5 Hope this helps

Answer:

[tex](x - 7) {}^{2} + (y + 1) {}^{2} = 16 \\ this \: is \: an \: equation \: of \: circle \\ ( {x}^{2} - 14x + 49) + ( {y}^{2} + 2y + 1) = 16 \\ {x}^{2} + {y}^{2} - 14x + 2y + 50 = 16 \\ {x}^{2} {y}^{2} - 14x + 2y + 34 = 0[/tex]

The question is incomplete had the number of harvested apples isn't given.

Answer:

0.06n

Step-by-step explanation:

When a farmer harvests apples he expects 6% of the apples to be rotten how many apples would the farmer expect to be rotting when harvesting apples

The expected percentage of rotten apples when harvesting = 6%

The expected number of rotten apples can be obtained by taking the product of the expected percentage and the number of apples to be harvested.

Since the number of harvested apples isn't given,

Let the number of harvested apples = n

Therefore, the expected number of rotten apples will be :

6% * n

0.06n

Note : you can easily substitute the actual number of harvested apples for n in the equto get the actual answer

Answer:

164 cubic units

Step-by-step explanation:

volume of a sphere = (4/3) x (n) x (r^3)

If volume = 4r^3

volume = 4 x (4)^3 = 164 cubic units

Step-by-step explanation:

Answer:

158 cases

Step-by-step explanation:

Given tbe quadratic regression model :

y = -2x^2 + 40x + 8

y = number of cases of a new disease

x = number of years

The predicted number of cases of a new disease in 15 years can be calculated thus ;

Put x = 15 in the equation ;

y = -2(15)^2 + 40(15) + 8

y = - 2 * 225 + 600 + 8

y = - 450 + 600 + 8

y = 158

158 cases
