Answer:

4522mm³

Step-by-step explanation:

7×50×9 + 28×7×7 = 4522

Answer:

4522 mm^3.4522 mm^3.

Step-by-step explanation:

Splitting this up into 2 prisms, one vertical and the other horizontal:

Volume of each prism = length * width * height:

Volume of the figure =

Horizontal + vertical prism

= 7 * 9 * 50 + 7* 7* 28

For the exponential expression, [tex]16^{1/4}[/tex] the simplified value is 2.

First, we need to remember a rule for exponential expressions, it says that:

[tex]x^{1/n} = \sqrt[n]{x}[/tex]

Then we can rewrite the given exponential expression as:

[tex]16^{1/4} =\sqrt[4]{16}[/tex]

So, we just need to find a number that when multiplied by itself 4 times, is equal to 16.

We know that:

2*2 = 4

Then:

2*2*2*2 = 2⁴ = 4*4 = 16

Then we can conclude that:

[tex]16^{1/4} =\sqrt[4]{16} = 2[/tex]

So the simplified value of the exponential expression is 2.

first up first.... i love your profile pic....

oh and the answer is 744..

please read the explanation... it always helps!!

Step-by-step explanation:

alrighty..

so the total budget is 1200, and we want to know how much is 62% of that

so you follow the percent formula as follows:

1200/100= 12 --> 12 x 62= 744 (which is the answer!)

The roots of this equation equation are:

x1 = 4

x2 = 8

This sentence given in the statement of this question is: Equation of the Second Degree. There are a few ways to solve it, but let's calculate by the factorization method.

Equation given: x² - 12x + 36 = 4

x² - 12x + 36 = 4

12x ➯ 2x . x6

36 ➯ 6²

x² - 2x . x6 + 6²

( x - 6 )² = 4

( x - 6 )² = 4

x - 6 = ±√4

x - 6 = ±2

x - 6 = ±2

x - 6 = -2

x - 6 = +2

x - 6 = -2

x = -2 + 6

x = 4

x - 6 = +2

x = 2 + 6

x = 8

Therefore, the correct results of this equation, will be:

x1 = 4

x2 = 8

By taking the product between the rate and the time, we will see that he does not finish the book.

We know that he can read 5 pages in 15 minutes. Then in one hour he can read 4 times that: 4*5 pages = 20 pages.

We conclude that Carter reads 20 pages per day, then, if he reads for 14 hours, then he reads a total of:

20*14 = 280

So he will read 280 pages in these 14 hours, which means that he will not finish the book.

Answer:

slope = - 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

x + y = - 7 ( subtract x from both sides )

y = - x - 7 ← in slope- intercept form

with slope m = - 1

Parallel lines have equal slopes

then the slope of a line parallel to it is - 1

Answer:

160 m

Step-by-step explanation:

Length of running track = Total Length of straight sections + Total length of curved sections

Solving :

⇒ 400 m = 2 x 120 m + Total Length of curved sections

⇒ Total Length of curved sections = 400 m - 240 m

⇒ Total Length of curved sections = 160 m

Let's get it solved ~

We have been given length and width of a rectangle in terms of x ~

that is :

Area of the rectangle is given ~ i.e 24 unit²

Area of rectangle in terms of x is :

[tex]\qquad \sf  \dashrightarrow \:(x - 2) \sdot(x + 3) = 24[/tex]

[tex]\qquad \sf  \dashrightarrow \: {x}^{2} + 3x - 2x - 6= 24[/tex]

[tex]\qquad \sf  \dashrightarrow \: {x}^{2} +x - 6 - 24 = 0[/tex]

[tex]\qquad \sf  \dashrightarrow \: {x}^{2} +x -30= 0[/tex]

[tex]\qquad \sf  \dashrightarrow \: {x}^{2} + 6x - 5x - 30 = 0[/tex]

[tex]\qquad \sf  \dashrightarrow \: {x}^{}( x + 6) - 5(x + 6)= 0[/tex]

[tex]f(x) = \begin{cases}x = - 6 \: \textsf{ \: if \:x + 6 = 0 } \\ \\ x = 5 \: \: \: \: \: \: \textsf{if \: x - 5 = 0} \end{cases}[/tex]

but since side of a rectangle can't be negative, we have to take value of x as 5

now, Perimeter of rectangle is ~

[tex]\qquad \sf  \dashrightarrow \:2(width \: + \: length)[/tex]

[tex]\qquad \sf  \dashrightarrow \:2(x - 2 + x + 3)[/tex]

[tex]\qquad \sf  \dashrightarrow \:2(2x + 1)[/tex]

plug In the value of x ~

[tex]\qquad \sf  \dashrightarrow \:2(2(5) + 1)[/tex]

[tex]\qquad \sf  \dashrightarrow \:2(10 + 1)[/tex]

[tex]\qquad \sf  \dashrightarrow \:2(11)[/tex]

[tex]\qquad \sf  \dashrightarrow \:22 \: \: units[/tex]

So, the correct choice is b~

The answer is

for parallel : x-4=0

for perpendicular: y+4=0

The slope-intercept form is written as y = mx+b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis). It's usually easy to graph a line using y=mx+b.

Given line: x=-7

The slope of line x=7 is infinite

The equation of line passing through point (4,-4) and having slope infinite is

0.y+x=-7

So, 0.y= 4

hence, x=4

slope intercept form

x-4=0

Now, for perpendicular lines:

swap the coefficients on x and y with negative sign of x in x=-7

This is a vertical line, so the perpendicular line will be a horizontal line of the form y=b.

Since we are given that the line should pass through the point (4,−4), then the equation of the line is y=−4.
