Answer:

Option A is the correct answer.

Explanation:

 The given pyramid has 3 lateral triangular side as shown below.

 Base of triangle = 12 unit

 We need to find perpendicular.

  By Pythagoras theorem we have

            Perpendicular² = 10²-6²

           Perpendicular = 8 unit

So area of 1 lateral triangle = 1/2 x Base x Perpendicular.

                                             = 1/2 x 12 x 8 = 48 unit²

Area of lateral side = 3 x 48 = 144 unit²    

Option A is the correct answer.                

Answer:

A

Step-by-step explanation:

(1)

we are given

U is the midpoint of RS

and we have

[tex]RU=12[/tex]

so, we can use formula

[tex]RS=2RU[/tex]

we can plug values

[tex]RS=2\times 12[/tex]

[tex]RS=24[/tex]............Answer

(2)

V is the midpoint of ST

so, we get

[tex]SV=VT[/tex]

now, we can plug values

[tex]2x=11[/tex]

divide both sides by 2

[tex]x=5.5[/tex].........Answer

(3)

now, we can find y

W is the midpoint of TR

so, we get

[tex]RW=WT[/tex]

we can plug value

[tex]15.9=3y[/tex]

divide both sides by 3

[tex]y=5.3[/tex]

(4)

we can see that

triangles URW and RST are similar

so, their sides ratios must be equal

so, we get

[tex]\frac{RW}{RT} =\frac{UW}{ST}[/tex]

we can plug values

[tex]\frac{15.9}{2\times 15.9} =\frac{UW}{2VT}[/tex]

[tex]\frac{15.9}{2\times 15.9} =\frac{UW}{2\times 11}[/tex]

[tex]UW=22\times \frac{15.9}{2\times 15.9}[/tex]

[tex]UW=11[/tex]...........Answer

(5)

we can see that

triangles SUV and RST are similar

so, their sides ratios must be equal

so, we get

[tex]\frac{SU}{SR} =\frac{UV}{RT}[/tex]

now, we can plug values

[tex]\frac{12}{2\times 12} =\frac{UV}{2\times 15.9}[/tex]

[tex]UV=2\times 15.9\times \frac{12}{2\times 12}[/tex]

[tex]UV=15.9[/tex].............Answer

1. The length of RS is 24 units.

2. The value of [tex]x[/tex] is 5.5.

3. The value of [tex]y[/tex] is 5.3.

4. The length of UW is 11.

5. The length of UV is 15.9.

According to the given figure-

[tex]\triangle RST \sim \triangle URW[/tex]

1. U is the mid-point of RS so, the length of UR and US are equal.

Hence, the length of RS is 24 units.

2. V is the mid-point of ST so, the length of VS and VT are equal.

So,

[tex]2x=11\\x=\dfrac{11}{2}\\x=5.5[/tex]

Hence, the value of [tex]x[/tex] is 5.5.

3. W is the mid-point of RT so, the length of WR and WT are equal.

So,

[tex]3y=15.9\\y=\dfrac{15.9}{3}\\y=5.3[/tex]

Hence, the value of [tex]y[/tex] is 5.3.

4. As, [tex]\triangle RST \sim \triangle URW[/tex]

So, the length of the sides is proportional.

[tex]\dfrac{RT}{RW}=\dfrac{ST}{UW}\\\dfrac{2\times 15.9}{15.9}=\dfrac{11\times 2}{UW}\\UW=11[/tex]

Hence, the length of UW is 11.

5.  As, [tex]\triangle RST \sim \triangle URW[/tex]

So, the length of the sides is proportional.

[tex]\dfrac{SU}{SR}=\dfrac{UV}{RT}\\\dfrac{12}{2\times 12}=\dfrac{UV}{2\times 15.9}\\UV=15.9[/tex]

Hence, the length of UV is 15.9.

The Algebra expression a/b + c²d with the given values (a=6, b=3, c=4, d=5) evaluates to 82. This involves steps of squaring, multiplication, division, and finally addition.

In order to evaluate the expression a/b + c²d, we substitute the given values into the expression. For this problem, the values given are a=6, b=3, c=4, and d=5. Thus, the expression becomes: 6/3 + (4)²(5).

First, we perform the operations in the parenthesis, which is 4 squared, or 4*4, which gives us 16.

Next, we multiply this result by d, which is 5. Therefore, 16*5 gives us 80.

Finally, we perform the division operation: a/b, that is 6 divided by 3, which equals 2.

Adding these two results together, 2 + 80, we get our final answer, which is 82.

Answer:

b is the base of function which help us to determine the growth rate and Also tells the multiplicity of fishes .

Step-by-step explanation:

Exponential Function: [tex]ab^x[/tex]  --1

a = initial value (the amount before measuring growth or decay)

b>1 growth

b<1 decay

The growth "rate" (r) is determined as b = 1 + r.

The decay "rate" (r) is determined as b = 1 - r

After observing the population growth over a few weeks, the exponential function :

[tex]P(t) = 7(2)^t[/tex]

Comparing it with 1

b  = 2

Since b >1

So, it is the growth function

So, The growth "rate" (r) is determined as b = 1 + r.

2 = 1+r

r = 1

Hence growth rate is 1

So, b is the base of function which help us to determine the growth rate and Also tells the multiplicity of fishes .

Graph 3 is exponential function.

Step-by-step explanation:

We are given four different graph. We need to choose exponential graph.

Graph 1: It is square root graph because the value of x and y not negative in this graph. Graph is slight curve.

[tex]f(x)=\sqrt{x}[/tex]

False

Graph 2: It is is cubic graph because it start from bottom of the coordinate plane and end at top of the coordinate plane.

[tex]f(x)=x^3[/tex]

False

Graph 3: It is exponential graph because range is all positive real number and domain is all real number.

[tex]f(x)=3^x[/tex]

True

Graph 4: It is rational function graph because here we have vertical asymptote (x=-2)

[tex]f(x)=\dfrac{1}{x+2}[/tex]

False

B) (4,24)

This is because you turn one of the equations you make, let's use x+4y=100, and turn it into y=mx+b form. This turns into y=(-x/4) +25 and if you plug in the number 4 as your x you get 24.

Answer:

√357

Step-by-step explanation:

multiply all three numbers together and since 357 cannot be simplified it stays as a radical

The radical form of √3 x √7 x √17 is √357.

When we have a number raised to a power that is less than one but greater than zero we call them surds and when we have numbers that have been raised by powers that are greater than one we call them indices.

Radical multiplications are the same as multiplying integers only we can not add radicals of different values under the square root.

∴ √3 × √7 × √17.

= √51 × √7.

= √357.

We can't simplify this more because the multiplication was of all prime numbers.

Answer:

16 dollars.

Step-by-step explanation:

Given that selling price of a back pack after reduced by 30% is 11.20 dollars.

We have to find the original price of the back pack.

Let original price = 100

Reduced %          =  30

Selling price         = 70

70 dollars is equivalent to selling price of 11.20 $

100 dollars is equivalent to selling price of 100(11.2)/70 = 16 $

i.e. original price of back pack is 16 dollars.

No need to look at the times.

Answer:

Temperature at 4 am is 66 degrees.

Step-by-step explanation:

First we have to count how many half an hour's are there from 6 pm to 4 am.

Number of hours from 6 pm to 4 am.  =  [tex]10[/tex] hours

Number of half an hours from 6 pm to 4 am.  = [tex]10*2[/tex]

                                                                           =[tex]20[/tex]

It is given that temperature drops [tex]1\frac{1}{4}[/tex] degrees every half an hour.

Therefore,

Temperature drop in 20 half an hours = [tex]1\frac{1}{4}*20[/tex] degrees

                                                                =[tex]\frac{5}{4} *20[/tex] degrees

                                                                =[tex]25[/tex] degrees

Temperature drops 20 degrees from initial 86 degrees.

Therefore, temperature at 4 am = 86 degrees - 20 degrees

                                                      = 66 degrees

Remember that [tex] 40 = 2\cdot 2\cdot 10 [/tex].

So, dividing by 40 means dividing by 10, then by 2, then by 2 again.

So, we can go like this: let's divide by 10 first

[tex] 13 \div 10 = 1.3 [/tex]

Then, we divide by 2:

[tex] 1.3 \div 2 = 0.65 [/tex]

And by 2 again:

[tex] 0.65 \div 2 = 0.325 [/tex]

So, the decimal expansion ends after 3 digits.
