Answer:

95.7

Step-by-step explanation:

Given that [tex]\sqrt{7569}=87[/tex] we're in search for the value of  [tex]\sqrt{7569} +\sqrt{75.69}[/tex].

Simplify the square roots.

[tex]\sqrt{7569} +\sqrt{75.69}[/tex]

[tex]87 + 8.7[/tex]

Now when we add we get 95.7 or 96 rounded to the nearest tenth.

Explanation:

Calculate the unit rate for the first bag

8 kg = 26.04 dollars

8/8 kg = 26.04/8 dollars ... divide both sides by 8

1 kg = 3.255 dollars

1 kg = 3.26 dollars  .... rounding to nearest cent

For the first bag, the unit rate is about 3.26 dollars per kg

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

Repeat for the second bag

9 kg = 29.15 dollars

9/9 kg = 29.15/9 dollars ........ divide both sides by 9

1 kg = 3.23888888888889 dollars (approx)

1 kg = 3.24 dollars  .... rounding to nearest cent

The unit rate for the second bag is roughly 3.24 dollars per kg

We see that the second bag's unit rate is cheaper by 2 cents, so it is the better deal. This is despite the fact that the entire bag costs more.

Answer:

The supplement is 102

Step-by-step explanation:

Supplementary angles add to 180 degrees

Let x be the supplement

x+ 78 = 180

subtract 78 from each side

x+78-78 = 180-78

x = 102

Answer:

$(x-100)

Step-by-step explanation:

His net winnings from the tournament will be the price minus the entry fee.

Therefore:

Phil's net winnings=$(x-100)

Answer:

x - 100

Step-by-step explanation:

Since it costs 100 dollars for Phil to enter the competition, you subtract that from the prize in which he earns (x).

Answer:

Since g(x) = 7x, we can substitute that into g(x) > which gives us 7x > 28. This simplifies to x > 4.

Answer:

x > 4

Step-by-step explanation:

g(x)=7x

g(x) >28

Replace g(x) with 7x

7x > 28

Divide by 7

7x/7 > 28/7

x > 4

Answer:

Power, P = 80 W

Step-by-step explanation:

We have,

Weight of athlete is 960 N

It runs through a flight of stair case in 2 mins or 120 second

There are 100 stairs and each stair case has a length of 100 mm  or 0.1 m

Power is given by :

[tex]P=\dfrac{Fd}{t}[/tex]

d is distance

For 100 stairs,

So,

[tex]P=\dfrac{960\times 100\times 0.1}{120}\\\\P=80\ W[/tex]

So, the power of an athlete is 80 watts.

Answer:

? = 7.45

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adjacent side/ hypotenuse

cos 20 = 7 / ?

Multiply each side by ?

? cos 20 = 7

Divide each side by cos 20

? = 7/ cos 20

? =7.449244407

To the nearest hundredth

? = 7.45

Answer:

7.45 units

Step-by-step explanation:

[tex]\cos 20\degree = \frac{BC}{AB}\\\\0.939692620 = \frac{7}{AB}\\\\AB = \frac{7}{0.939692620}\\AB = 7.4492\\AB = 7.45 units[/tex]

Answer:

$2.75

Step-by-step explanation:

We know that the random persons total was $5.50. To figure out how much one loaf of bread costs we must first, divide $5.50 by 2. We get 2.75. Then, to double check our answer we multiply that by 3 to get 8.25. We know that Micah' s total was $9.00. 9 minus 8.25 equals 0.75.

That price is very reasonable, for a jug of milk, so we know that $2.75 is the answer.

Answer: y=3x^2+3x-3

(the first option)

Answer:

3y²+3x-3

Step-by-step explanation:

the first choice

Answer:

10, 11 and 12.

Step-by-step explanation:

A number has 5 as one of its factors, when last digit is 5 or 0. Only prime numbers have 1 as the only factor and a number has 2 as one of its factors when last digit is 2, 4, 6, 8 or 0.

Three possible consecutive numbers are 10, 11 and 12. 10 is the product of 2 and 5, 11 is a prime number and 12 is the product of 3 and 2². Therefore, possible choice is 10, 11 and 12.

Answer:

2.41 and 2.50

Step-by-step explanation:

Here, we shall be selecting the correct answer from the option.

a. A is correct

the number we want is between 2.4 and 2.8

2.5 is greater than 2.4 but less than 2.5, this means it meets our criteria

b. 2.41 is also correct

This is because it is greater than 2.4 but less then 2.8

c. wrong

2.4 is same as 2.4, it does not meet the criterion

d. wrong

the value is far lesser than 2.4

Answer:

My best answer. Hope this helps...

Step-by-step explanation:

You can see 1 full square in the triangle.

There are also 3 half squares.

The top part of the triangle also equals to 1 half square.

On the bottom right side, you have two shapes that add up to a square.

4 half squares = 2 full squares.

2 + 1 + 1 = 4

The square also has 4 squares.

Answer: b.2x

Step-by-step explanation:

why? because 2 can be divided into all of the numbers evenly!

all the numbers have (x)

it wouldn't be (2x^2) ,because one of the numbers have x^3

Answer:

2x^2

Step-by-step explanation:

You find what the highest number they all have in common in this case 2 then if they all have x or y in common they have x^2 in common then add the two together making 2x^2

Answer:

128 or 4,096

Step-by-step explanation:

If its 64 x 2 then 128 or if you are implying 64, to the power of two, (64x64) then your answer is 4,096.

The simplified value is 4096.

Algebraic identities are equations where the value of the left-hand side of the equation is identically equal to the value of the right-hand side of the equation. Unlike algebraic expressions, algebraic identities satisfy all the values of the variables.

The basic algebraic identities are primarily helpful to work out the numerous math problems. The four basic algebraic identities are as follows.

Given:

64²

Now, we have to split the 64 into 60+4

(60 + 4)²

Now using the algebric identity

(a+ b)² = a² + b² + 2ab

So,

(60 + 4)²

=60²+2*60*4+4²

=3600+ 480+16

=3600+496

=4096

Hence, the simplified value is 4096.
