What is the product ([tex](7\sqrt{8} +3\sqrt{12} )(7\sqrt{8} -3\sqrt{12})[/tex]?

Answer:

Explanation:

2 ½: 2.5

3 ⅕: 3.2

Base: 3.2

Height: 2.5

3.2 · 2.5 = 8

Answer:

No.

Step-by-step explanation:

Well, is the points (1, -9) does satisfy the equation y = 3x - 6. Then, substituting the values of x, and, y, into the equation y = 3x - 6,  we should get a true equation.

y = 3x - 6

-9 = 3 * 1 - 6

-9 = 3 - 6

-9 = -3.

So, the points (1, -9) does not satisfy the equation y = 3x - 6.

Answer:

26.5 units

Step-by-step explanation:

The height of the ball at any time t is given by :

[tex]h(t)= -16t^2 + 40t + 1.5[/tex] ...(1)

We need to find the maximum height of the ball.

For maximum height, put [tex]\dfrac{dh}{dt}=0[/tex]

i.e.

[tex]\dfrac{d( -16t^2 + 40t + 1.5)}{dt}=0\\\\-32t+40=0\\\\t=\dfrac{40}{32}\\\\t=1.25\ s[/tex]

Put t = 1.25 in equation (1) to find the maximum height.

So,

[tex]h(t)= -16(1.25)^2 + 40(1.25) + 1.5\\\\=26.5\ units[/tex]

So, the maximum height reached by the ball is 26.5 units.

Answer:

n = 64

Step-by-step explanation:

3/4n - 8 = 5/8n

-8 = 5/8n - 6/8n

-8 = -1/8n

-n = -64

n = 64

The unknown number is 64.

Important information:

[tex]\dfrac{3}{4}[/tex] of a number [tex](n)[/tex] is [tex]\dfrac{3}{4}n[/tex].

Difference between [tex]\dfrac{3}{4}[/tex] of a number [tex](n)[/tex] and 8 is [tex]\dfrac{3}{4}n-8[/tex].

[tex]\dfrac{5}{8}[/tex] of the number is [tex]\dfrac{5}{8}n[/tex].

Using the given information form a linear equation.

[tex]\dfrac{3}{4}n-8=\dfrac{5}{8}n[/tex]

Now, solve the equation.

[tex]\dfrac{3}{4}n-\dfrac{5}{8}n=8[/tex]

[tex]\dfrac{6n-5n}{8}=8[/tex]

[tex]\dfrac{n}{8}=8[/tex]

Multiply both sides by 8.

[tex]n=64[/tex]

Therefore, the unknown number is 64.

131m

Step-by-step explanation:

274.5÷4.5=61

4.5m×2=9m

61m×2=122

122m+9m=131m

Answer:

Perimeter = 131 m

Step-by-step explanation:

Area=Length x Width so:

274.5 = 4.5 x Width

Width = 274.5/4.5 = 61 m

Perimeter = 2 Widths + 2 Lengths so:

Perimeter = 2(4.5)+2(61 )= 131 m

Number of sponges = Number of packages

Hence:

s sponges = 1 Package

14 sponges = x

Cross Multiply

s × x = 14 × 1

x = 14/s

Therefore, the expression that shows how many packages Bonnie bought.is given as

Step-by-step explanation:

The 3 triangles are all similar.

Using the 2 inside then the ratios of corresponding sides are equal, that is

[tex]\frac{x}{3}[/tex] = [tex]\frac{12}{x}[/tex] ( cross- multiply )

x² = 36 ( take the square root of both sides )

x = [tex]\sqrt{36}[/tex] = 6 → C

Answer:

C) x = 6

because this is a right triangle

=> we have:

(12² + x²)(3² + x²) = (15x)²

<=> 1296 + 153x² + x⁴ = 225x²

<=> x⁴ - 72x² + 1296 = 0

<=> (x² - 36)² = 0

<=> x² = 36

=> x = 6

Answer:

608,900

Step-by-step explanation:

it is hard to explain, but here is the answer

The number 608,897 to the nearest tens is 608,900.

Rounding off is the method of simplifying a number to the next closest number by maintaining it's value.

Rounding can be done for decimals as well as whole numbers. Rounding can be done to different place values like tens, hundreds, and in decimals, tenths, hundredths, etc. can be done.

The given number is 608,897.

We have to round this to the nearest ten.

For that, we have to consider the digits in the place values ones and tens.

The digit in the ones is 7. Replace it with 0.

Since the digit in the ones is greater than 5, the digit in the tens column get increased by 1. So 9 in the tens column become 10. By keeping 0 at the tens column 1 is given to the next place value, hundreds. So the digit on the hundreds value which is 8 get increased by 1 and become 9.

Thus the number 608,897 is rounded to 608,900.

Hence the number 608,897 can be rounded off to the nearest tens as 608,900.
