Answer:

c

Step-by-step explanation:

Answer:

The answer is A

Step-by-step explanation:

7 + -8 = -1

-6 + -7 = -13

2 + 5 = 7

6 + -1 = 5

-5 + -9 = -14

-7 + 7 + 0

you can then eliminate B.

and only A is left.

Answer:

63

Step-by-step explanation:

use tangent formula

[tex] \tan(40) = \frac{h}{75} [/tex]

Answer:

h ≈ 62.9 ft

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{h}{75}[/tex] ( multiply both sides by 75 )

75 × tan40° = h , then

h ≈ 62.9 ft ( to 1 dec. place )

Answer: B

Step-by-step explanation: left 6, down 5

Answer:

If y = 80 then 5x+36 also equals 80

80 - 36 = 44

therefore 5x = 44

44 / 5 = 8.8

x=8.8

Answer:

0.87

Step-by-step explanation:

Out of a total number of 100 questions, Daniel is said to have answered 87.

We first express this as a fraction.

Total number of questions he answered divided by total number of quiz questions

= 87/100

As a decimal, 87 divided by 100 = 0.87.

You can easily get this by using the calculator.

Thank you!

Answer:

Step-by-step explanation:

0.87 because 87+0=87

Answer:

$3000

Step-by-step explanation:

Look at where the x value is equal to 100 and look at what value the purple line intersects with when it reaches 100

you can see that when the purple hits 100 it is also on the 3000 line

Answer:

2

Step-by-step explanation:

[tex]\begin{cases} -3x -3\:\: for\:\: x<-2\\\\6x -28\: \: for\:\: x\geq 5  \end{cases}[/tex]

f(5) will fall in the interval x≥5 and its corresponding function is:  

    f(x) = 6x - 28

∴ f(5)= 6*5 - 28 = 30 - 28 = 2

Answer:

HCF = 14

LCM = 1680

Step-by-step explanation:

Factorizing the given values

210 = 2 * 3 * 5 * 7

112 = 2 * 2 * 2 * 2 * 7

Since 2 * 7 is common to both factors

Hence the HCF = 2 * 7 = 14

For LCM, we we will multiply all the prime factors that are in both

LCM = 2* 2 * 2 * 2 * 3 * 5 * 7

LCM = 112 * 15

LCM = 1680

Hence the LCM is 1680

aswer..RICHARD IS 20YEARS ODL

AND TEO IS 9YEARS OLD

Answer:

0.0078125

Step-by-step explanation:

Probability of tail, p = 0. 5

Probability of getting all tails from 7 tosses :

P(tail) * P(tail) * P(tail) * P(tail) * P(tail) * P(tail) * P(tail)

0.5 * 0.5 * 0.5 * 0.5 * 0.5 * 0.5 * 0.5 = 0.0078125

We could also use the binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - r)

n = 7 ; x = 7, p = 0.5,

P(x = 7) = 7C7 * 0.5^7 * 0.5^0 = 0.0078125

Answer:

in this order (0,0) (1,2) (2,4) (3,6)

Step-by-step explanation:

pls mark brainliest

I can't see pictures, but to graph y=2x, you have to make 2x into slope form.

Just write 2 as a fraction, or 2/1. 2 is the rise, and 1 is the run. So start at the origin, or (0,0), and go up 2 units, then 1 unit right. So you start at (0,0), then now you should be at (1,2). Repeat the process to make a straight line.

Answer:

$0.84 I think is the answer

Answer:

x = 0 and y = 4.

Step-by-step explanation:

The given equations are :

4x+2y=8 ...(1)

x+y=4 ...(2)

Multiply equation (2) by 2.

2x+2y=8 ...(3)

Subtract equation (3) from (1).

4x+2y-(2x+2y)=8-8

4x+2y-2x-2y=0

2x = 0

x = 0

Put the value of x in equation (2).

0+y=4

y = 4

So, the value of x and y are 0 and 4.

Answer:

the mean is 3.95

median is 2.75

Step-by-step explanation:

I'd say that the mean is the better center, because you need to even it all out. you have one big number compared the rest.

The median is a better center for this data since since that number is the common size of acres not the highest or lowest acre per 1000 residents

Answer:

I think it would be C. 9/13.

Answer:

B

Step-by-step explanation:

11/26 x 7/26 = 77/676

Answer:

The first one is TRUE.

You would convert the 1/2 into 4/8 to compare them and you will see that 3/8 is less than 4/8 or 1/2

Answer:

a baby weight more because the baby will grow and will weight more then a puppy

Step-by-step explanation:

Answer:

A puppy that weights 8.5 kilograms weighs more.

Step-by-step explanation:

A puppy that weights 8.5 kilograms weighs more. Why? Well if you convert the 11 pounds from the baby to kilograms it would equal about 5 kilograms. The puppy's weight in kilograms is 8.5 and its weight in pounds is 18.7, while the baby's weight in kilograms is 5 and it's weight in pounds is 11.

Puppy's Weight Kilograms: 8.5

Puppy's Weight Pounds 18.7

Baby's Weight Kilograms: 5

Baby's Weight Pounds: 11

Weight in Kilograms: Puppy: 8.5 > Baby: 5

Weight in Pounds: Puppy: 18.7 > Baby: 11

Therefore, the puppy is heavier.

Answer:

{ x | x < 2 or x > 8}

Step-by-step explanation:

Given the expression

(x + 3 < 5) U (x - 7 > 1).

Solve x+3 < 5

Subtract 3 from both sides

x+3 - 3 < 5-3

x < 2

For x - 7 > 1

Add 7 to both sides

x-7+7 > 1 + 7

x > 8

Hence the union of both is { x | x < 2 or x > 8}
