Answer 1

Answer:

value of a in terms of b and c is: [tex]\mathbf{a=bc}[/tex]

Option D is correct.

Step-by-step explanation:

We are given:

[tex]a=b^2c^2d \:and\: d=\frac{1}{a}[/tex]

We need to find a in terms of b and c

We have: [tex]a=b^2c^2d[/tex]

Put value of d [tex]d=\frac{1}{a}[/tex]

[tex]a=b^2c^2(\frac{1}{a})\\a^2=b^2c^2\\Taking \:squareroot\:on\:both\:sides\\\sqrt{a^2}=\sqrt{b^2c^2}\\a=bc[/tex]

So, value of a in terms of b and c is: [tex]\mathbf{a=bc}[/tex]

Option D is correct.

A wheel on a bicycle has a radius of 8 inches. what is the distance it covers if the tire makes 2 full rotations?

Answers

A wheel on a bicycle has a radius of 8 inches. The distance it covers if the tire makes 2 full rotations will be equal to 100.48 inches.

The distance covered by the wheel on a bicycle can be determined by using the formula:

distance traveled = 2 x circumference of the wheel

Where 2 is the number of rotations.

The circumference can be found by using the radius of the wheel in the formula:

C = 2π(r)

C =2π(8)

C =16π

Distance traveled can then be found by:

distance traveled = 2x16π

distance traveled =32π

As π = 3.14

distance traveled= 32 x 3.14 = 100.48 inches

Therefore, the distance covered by the wheel on a bicycle is equal to 100.48 inches if the tire makes 2 full rotations.

Find the HCF and LCM of 160 and 252 by prime factorisation method and verify that HCF x LCM = Product of the two given numbers.

Answers

Answer:

HCF=4

LCM=10080

HCF x LCM = Product of the two given numbers is verified because 403200=40320

Step-by-step explanation:

HCF of 160 and 252

HCF is the product of common prime factors

Prime Factorisation of 160: 2x2x2x2x2x5

Prime Factorisation of 252: 2x23x3x7

HCF= 2x2

HCF=4

40 and 63 doesn't come in any other table together so,

HCF= 2 x 2 = 4

Now, finding LCM of 160 and 252

LCM is the product of all factors of both numbers, while if any factor is common, it is considered once.

Prime Factorisation of 160: 2x2x2x2x2x5

Prime Factorisation of 252: 2x23x3x7

In the given factors 2x2 is common so, it is considered once.

LCM= 2x2x2x2x2x3x5x7

LCM= 10080

Now, checking:

HCF x LCM = Product of the two given numbers.

4x10080=160x252

403200=40320

So, It is verified that HCF x LCM = Product of the two given numbers.

ethan claims that [7-3]=4. which statement about ethan claims is true

Answers

Answer:

no its not

Step-by-step explanation:

7 - 3 = ? not 4 so sub it

Answer:

Ethan's entire statement is true because he is saying that 7-3=4 and that is correct. If you have seven of something and take away 3 of them then you have 3 left.

Step-by-step explanation:

Take 7 apples for example, if you take away 3 of the apples and then count the left over you will notice that you end up with 4. Also, In a subtraction problem the larger number goes first followed by the smaller number, so that the end result is not a negative number. Hope this helps you.

I I 2x+1 I +2 I >1, step by step solution (I I is absolute value)

Answers

The absolute value of x in the inequality I 2x+1 I +2 I >1 showing the step by step solution is x > 2

What is absolute value?

The absolute value of a real number x can be defined as the non-negative value of x without regard or consideration to its sign.

It is also known as the modulus of a number.

It is sometimes described as the magnitude of a real number regardless of its sign.

It is important to note that the absolute value must take a positive sign

Given the expression;

I I 2x+1 I +2 I > 1

expand the modulus value

2x + 1 + 2 > 1

collect like terms

2x > 1 + 1 + 2

Add like terms

2x > 4

Make 'x' the subject

x > 4/ 2

x > 2

Thus, the absolute value of x is x > 2

does anybody know it ??

Answers

Answer: 220/221

==========================================================

Work Shown:

The given values are

sin(u) = -12/13cos(v) = -8/17

Through the Pythagorean trig identity, we can find

cos(u) = -5/13sin(v) = -15/17

I'm skipping these steps, but let me know if you need me to go over them.

Since u and v are in quadrant 3, this means both sine and cosine are negative here

Using those four items, we can then say the following:

cos(v-u) = cos(v)cos(u) + sin(v)sin(u)

cos(v-u) = (-8/17)*(-5/13) + (-15/17)*(-12/13)

cos(v-u) = 40/221 + 180/221

cos(v-u) = (40 + 180)/221

cos(v-u) = 220/221

This is reduced as much as possible because the GCF of n and n+1 is always 1.

Hope it can give u some help

hello

so what we can gather form the diagram given is that all the angles there will add up to 360°.

we can see that they have given one of the angles as 90° as indicated by the little square. so the first step to find x, we need to subtract 90 from 360.
360-90=270

now, we can form an equation to find x. we need to add the other two angles (x, 3x) and then make them equal to 270°.
3x+x=270
add like terms
4x=270
divide by 4
x=67.5°

hope this helps
