A wall contains four windows of size 2.5 m X 1.6 m each and two gets of size 2 m x 3 m. If the length, breadth and the height of the wall are 50 m, 30 cm and 6 m respectively, find the volume of wall excluding the windows and gates.​

Answer:

[tex]x=6[/tex]

Step-by-step explanation:

Pythagorean Theorem: [tex]AC^2+BC^2=AB^2[/tex]

BC= x

AB= 10 cm

AC= 8 cm

~

Now, Substitute

[tex]8^2+x^2=10^2[/tex]

[tex]64+x^2=100[/tex]

[tex]100-64=x[/tex]

[tex]\sqrt{36}=x^2[/tex]

Square root x^2= x, √(36)=6

[tex]x=6[/tex]

Therefore, the length of x = 6

Answer:

[tex]1\frac{2}{3}[/tex]

Step-by-step explanation:

INFORMATION/REMINDS ALREADY KNOWN:

We need to find the whole number first, which we accomplish by dividing the numerator by the denominator. We ignore any digits to the right of the decimal point since we are only interested in whole numbers.

[tex]35/21= 1.6666666666667 = 1[/tex]

Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.

We'll use the whole number we calculated in step one (1) and multiply it by the original denominator to figure this out (21). The numerator is then subtracted from the result of that multiplication:

[tex]35 - (21 * 1) = 14[/tex]

We've now simplified 35/21 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:

[tex]1\frac{14}{21}[/tex]

Our fraction (14/21) can be simplified even more in this example. To do so, we must determine the GCF (greatest common factor) of those two numbers. If you want to do it yourself, you can use our handy GCF calculator. We've done it earlier, and the GCF of 14 and 21 equals 7.

We can now divide both the new numerator and the denominator by 7 to simplify this fraction down to its lowest terms.

[tex]\frac{14}{7} = 2\\\frac{21}{7} = 3[/tex]

When we put that together, we can see that our complete answer is:\

[tex]1\frac{2}{3}[/tex]

Hope this helps :)

Answer:

B. A web diagram shows what connects these different types of doctors.

Step-by-step explanation:

The actual price is $46.73 lower than the expected price.

[tex]CPI_t=\frac{C_t}{C_0} * 100[/tex]

CPI=consumer price index in the current period

Ct= expected cost in current period

C₀ =cost in the base period

It is given that

Price in base period ie 1983 C₀= $78.75

The actual cost of the microwave oven = $92.66

Consumer Price Index= 177

So, expected price of microwave oven in the current period

Ct= CPIt * C₀ /100 = 177*78.75/100 = $139.39

Difference between the actual price and expected price = 139.39-92.66=$46.73

Therefore, The actual price is $46.73 lower than the expected price.

Hi! I hope you're enjoying your day!

I can help Maritza solve this maths problem. ;)

The first step in solving this problem is using the Distributive Property and distribute 5.

How to distribute 5:

multiply 5 times 4m and -6 and simplify :)

So let's do it! :)

5(4m-6)-10

20m-20-10

Now, combine like terms:

[tex]\boxed{\boxed{\bold{20m-30}}}[/tex]

And yeah, we can't simplify this expression, because 20m and -30 are not like terms.

Hope everything is clear.

Hello there! Your question is missing some important information to solve.  I will solve the equation by simplifying the expression. =)

Answer:

[tex]20m-40[/tex]

Step-by-step explanation:

Given the expression:

[tex]5(4m-6)-10[/tex]

You can simplify it as follows:

1. Apply the Distributive Property multiplying each term inside the parentheses by the number 5 outside:

[tex]=(5)~(4m)-(5)~(6)-10[/tex]

[tex]=20m-30-10[/tex]

2. Add the like terms (remember that like terms have the same variables with the same exponents):

[tex]=20m-40[/tex]

Hence, the answer is [tex]20m-40[/tex]

(x + 10)(x - 10)

Step-by-step explanation:

x² - 100 = x²- 10²

x² - 100 is the difference of two squares.

The factorization of the difference of two squares is

a² - b² = (a + b)(a - b)

x² - 100 = (x + 10)(x - 10)

We will use graphical method to solve it.

The inequalities are

Graph both

We can see that the solution region is rightwards

The solution is (1.2,0.8)

Option D as the intersection point is ahead 1 unlike option A

Answer:

Given system of inequalities:

[tex]\large\begin{cases}y < \frac{2}{3}x\\y\geq-x+2\end{cases}[/tex]

When graphing inequalities:

[tex]y < \dfrac{2}{3}x[/tex]

The slope of the first inequality is 2/3, therefore at x = 1, y = 2/3.

So the correct line for the first inequality is the dotted line with the shallower slope.

As the relation is < for this inequality, the shading should be below the dotted line.

[tex]y\geq-x+2[/tex]

From inspection of the given graphs, the line of the second inequality (solid line) is the same in all graphs.

As the relation is ≥ for this inequality, the shading should be above the solid line.

Therefore, the only graph that satisfies these conclusions is graph D (attached).

Answer:

Multiply length by width to get area.

Step-by-step explanation:

Knowing the angles are equal, the value for y is 40.

The angle bisector is the line segment that divides the angle into two equal angles.

Thus, if OF is the angle bisector for EOG, the angles EOF and FOG are equal.

For finding y, you can write:

EOG=FOG

y+30=3y-50

y-3y=-50-30

-2y=-80

y=80/2

y=40

Answer:

cos2t/cos²t

Step-by-step explanation:

Here the given trigonometric expression to us is ,

[tex]\longrightarrow \dfrac{cos^4t - sin^4t }{cos^2t } [/tex]

We can write the numerator as ,

[tex]\longrightarrow \dfrac{ (cos^2t)^2-(sin^2t)^2}{cos^2t } [/tex]

Recall the identity ,

[tex]\longrightarrow (a-b)(a+b)=a^2-b^2[/tex]

Using this we have ,

[tex]\longrightarrow \dfrac{(cos^2t + sin^2t)(cos^2t-sin^2t)}{cos^2t}[/tex]

Again , as we know that ,

[tex]\longrightarrow sin^2\phi + cos^2\phi = 1 [/tex]

Therefore we can rewrite it as ,

[tex]\longrightarrow \dfrac{1(cos^2t - sin^2t)}{cos^2t}[/tex]

Again using the first identity mentioned above ,

[tex]\longrightarrow \underline{\underline{\dfrac{(cost + sint )(cost - sint)}{cos^2t}}}[/tex]

Or else we can also write it using ,

[tex]\longrightarrow cos2\phi = cos^2\phi - sin^2\phi [/tex]

Therefore ,

[tex]\longrightarrow \underline{\underline{\dfrac{cos2t}{cos^2t}}}[/tex]

And we are done !
