i think its 3

Step-by-step explanation:

Answer:

Step-by-step explanation:

a = 2i + 3j + zk

b = xi + 1j + 4k

Given a X b = 6i -14j +5k

a X  b  = | i   j   k|

              |2  3   z|

              |x   1    4|

a X b = i(12-z) - j(8 - xz) + k(2-3x) = 6i -14j +5k

equate the coefficients of i , j and k

12- z = 6;  implies z = 6

8 - xz = -14 implies 8 - 6x = -14

2-3x = 5     implies 2 - 3x = 5 implies  x = -1

Answer:

1/8 * 3

Step-by-step explanation:

1/8*3 means the numerator gets multiplied by 3 so we get (1*3)/8 which is 3/8

The equivalent value of the fraction is A = 3/8 = ( 3/4 ) ( 1/2 )

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first fraction be p

Let the second fraction be q

Now , A = pq

when the value of p = 3/4

And , when the value of q = 1/2

On simplifying the equation , we get

3/8 = ( 3/4 ) ( 1/2 )

So , the left hand side of the equation is equated to the right hand side by the value of ( 3/4 ) ( 1/2 )

A = ( 3/4 ) ( 1/2 )

A = 3/8

Therefore , the value of A = 3/8 = ( 3/4 ) ( 1/2 )

Hence , the fraction is A = 3/8 = ( 3/4 ) ( 1/2 )

Scale factor for the dimensions of the gymnasium on the blue print will be represented by the expression,

Scale factor = [tex]\frac{\text{Dimension of the blueprint}}{\text{Dimension of the original}}[/tex]

Length of the gymnasium = [tex]96[/tex] feet

Length of the gymnasium on the blueprint = [tex]5.5[/tex] inches

Therefore, scale factor for the blueprint = [tex]\frac{5.5}{96}[/tex]

                                                                  = [tex]0.0573[/tex]

If the width of the gymnasium = [tex]75[/tex] feet

For the width on the blueprint,

[tex]0.0573=\frac{\text{Width on the blueprint}}{75}[/tex]

Width on the blueprint = [tex]4.29[/tex]

                                      ≈ [tex]4.3[/tex] inches

Therefore, width of the gymnasium on the blueprint will be [tex]4.3[/tex] inches.

Answer: 600 canned foods was the total.

Step-by-step explanation: We need to find out what‘s 100% of 480. Since 480 canned foods is 80%, we can divide 480 by 8 which gives us 60. Aka 60 canned foods = 10%. Now, we multiply 60 by 10 which gives us 600. Hope this helps!

Answer:

200,000

Step-by-step explanation:

Step one:

given data

We are given that 15% of a non-profits Donations is about 30,000

Required

The amount in total received in donation

Step two:

Let the total donation be x

so

15/100*x= 30000

solve for x

0.15*x= 30000

divide both sides by 0.15

x= 30000/0.15

x=200,000

Hence the total donation is about 200000

Let x = 8.132132132... .

Then 1000x = 8132.132132132... .

Subtracting x from 1000x eliminates the fractional part, leaving you

999x = 8132 - 8 = 8124

Then

x = 8124/999 = 2708/333

Answer:

Step-by-step explanation:

Answer:

0m

Step-by-step explanation:

Before the ball is thrown, it is at the ground level. At the ground level, the height is zero. Substitute h = 0 into the equation;

h(x)=-x^2+10x-16

0=-x^2+10x-16

x^2-10x+16 = 0

Factorize

x^2-8x-2x+16 = 0

x(x-8) - 2 (x-8) = 0

x-2 = 0 and x - 8 = 0

x = 2 and 8

At x = 2

h(2) = -2^2 + 10(2) - 16

h(2) = -4 + 4

h(2) = 0

Hence the height of the ball at the time it is thrown is 0m

Step-by-step explanation:

x=volume of the glass

(1/3)x+63=(5/8)x

63=(5/8)x-(1/3)x

63=(15/24)x-(8/24)x

63=(7/24)x

multiply both sides by 24/7

(24/7)(63)=(24/7)(7/24)x

216=x

216 cm3 is the volume (answer)

1/3 of 216 is 72

72+63=135

135/216=0.625=5/8
