Answer:

1. [tex]4\sqrt{5}[/tex]

2. [tex]10\sqrt{10}[/tex]

Step-by-step explanation:

When you multiply radicals, you do the following

[tex]a\sqrt{b}\cdot c\sqrt{d}\\\\=ac\sqrt{bd}[/tex]

with that in mind

1.

[tex]\sqrt{16}\cdot \sqrt{5}[/tex]

here we don't need to multiply 16 times 5, because 16 = 4^2 and take the square root of it, gives you 4

[tex]=4\sqrt{5}[/tex]

2.

[tex]\sqrt{20}\cdot 5\sqrt{2}\\\\\longrightarrow 20 = 2^2\cdot 5\\\\=2\sqrt{5}\cdot5\sqrt{2}\\\\=(2\cdot5)\sqrt{5\cdot2}\\\\=10\sqrt{10}[/tex]

Answer:

$2.5389

Step-by-step explanation:

Given data

Cost of lunch = $2.34

Tax= 8.5%

Let us compute the cost of the tax

=8.5/100*2.34

=0.085*2.34

= $0.1989

Hence the total is = 0.1989+2.34

=$2.5389

Answer:

copy and paste that into math .way

Step-by-step explanation:

Answer: no solution

Step-by-step explanation:

x = 4

it would be -1/2 = 0 so that's not right

x = 0

it would be 1 = -2

well the first and second won't work.

all real numbers doesn't seem like the right answer

so best answer would be no solution.

Divide total price by quantity:

0.89 / 3 = 0.296 = 0.30

It would cost C. 30 cents

Answer:

B (I believe)

Step-by-step explanation:

89 divided by three equals 29.6666 (the number of sixes goes on forever)

but that is'nt a number on here, so just round down to 28¢

Hope this helped!!! :3

Answer:

System of Equations

3x + 1.5y = 18..... Equation 1

x = 3y ... Equation 2

This is not viable

Step-by-step explanation:

Let us represent

Number of roses = x

Number of camations = y

Juan is buying flowers for his mother. He has $18 to spend and sees that roses are $3 each and camations are $1.50 each.

$3 × x + $1.50 × y = $18

3x + 1.5y = 18..... Equation 1

He wants to buy 3 times as many camations as roses

y = 3x.... Equation 2

Therefore:

System of Equations

3x + 1.5y = 18..... Equation 1

x = 3y ... Equation 2

This is not viable

Answer:

f

Step-by-step explanation:

from what i know you do division first so when you do that you get

.83 repeasted add theat to 46 and you ger 45.83 with the three repeated

Answer:

To write 45 as a fraction with a common denominator, multiply by 6/6.

45⋅6/6+5/6=50

Combine 45 and 6/6.

(45⋅6)/6+5/6=50

Combine the numerators over the common denominator.

(45(6+5))/6=50

Simplify the numerator.

275/6=50

Answer:

36/8

or 4 1/2 foot tall

Step-by-step explanation:

6x6=36

36÷8=4 1/2

Answer: (9/2)

Step-by-step explanation:

If there are 6 pieces that are (6/8) of a foot tall, then they need to all be added together. Another way of doing this is to multiply (6/8) by 6:

(6/8) x 6= (36/8)

Then simplify:

=(9/2)

yup shes right, the girl above meh

Answer:

the answer is 27x all you do is multiply the 9 and the 3 and get 27 and then add the X to it

Step-by-step explanation:

Answer:

64 3/16 miles

Step-by-step explanation:

Total distance walked = 16 3/4 miles = 67/4 miles (converted to improper fraction to help with division later)

number of days walked = 4 days

Miles walked per day = total distance walked ÷ number of days

= 16 3/4 ÷ 4

= 67/4  ÷ 4

= 67/4 x 1/4

= 67/16

= 64 3/16 miles

Step-by-step explanation:

Slope-intercept form: y = mx + c

We have m = 1/4. Since it passes through the

point (-4, 2), => When x = -4, y = 2.

=> (2) = (1/4)(-4) + c, 2 = c - 1, c = 3.

Hence the equation is y = x/4 + 3.

Answer:

$287.50

Step-by-step explanation:

31.25 x 9.20 = $287.50

Answer:

$287.50

Step-by-step explanation:

1st multiply $9.20 by 31 (which is equal to $285.20)

then divide $9.20 by 4 ($2.30)

then add both answers and you will get $287.50

Answer:

the expression is 3 + ( - 4) so as you can tell there are more

negative than positive as you can see in the table you first add 3 than you add -4 which you get -1

Answer:

vertical 7 and 4

supplementary 5 and 1

Answer:

1. vertical angles: <2 and <5

2. Supplementary angles: <6 and <2

Step-by-step explanation:

Vertical angles are angles that are opposite to each other

-they will always have the same measure

-examples from the picture: 2 and 5, 6 and 1, 3 and 8, 7 and 4

Supplementary angles are angles that add up to 180

-they will always be able to form a straight line

-examples from the picture: 1 and 5, 6 and 2, 1 and 2, 5 and 6, 3 and 7, 7 and 8, 3 and 4, 8 and 4

Answer:

X=20°

Step-by-step explanation:

Angle in a straight line is 180°

=> 7x+40°=180°

=> 7x=180°-40°

=> 7x=140°

=> x=20°

Hope this helps you.

x = 2 works lol

but if you want a more complicated one:

4x - 4 = 4

there's infinite equations

Answer:

Step-by-step explanation:

Answer:

x = 10

Step-by-step explanation:

Our equation is: 2(x+3)+2 = 4x - 12

Distribute: 2x+6+2 = 4x - 12

Combine like terms: 2x + 8 = 4x - 12

Rearrange terms: 8 + 12 = 4x - 2x

Simplify: 20 = 2x

Therefore: x = 10

Answer:

a) AUB = { 1 ,2 , 3, 4, 5, 6, 8, 10}

b) A∩ B =  { 2, 4, 6 }

c) A-B = { 8 , 10}

Step-by-step explanation:

Step(i):-

Given that the sets

      U = { 1,2,3,4,5,6,7,8,9,10}

      A = { 2,4,6,8,10}

     B = { 1,2,3,4,5,6}

AUB = { 2,4,6,8,10} U  { 1,2,3,4,5,6}

AUB = { 1 ,2 , 3, 4, 5, 6, 8, 10}

Step(ii):-

A∩ B = {  2 ,4, 6, 8,10} ∩ { 1,2,3,4,5,6} = { 2, 4, 6 }

A-B = { 2,4,6,8,10} - { 1,2,3,4,5,6} = { 8 , 10}

Final answer:-

a) AUB = { 1 ,2 , 3, 4, 5, 6, 8, 10}

b) A∩ B =  { 2, 4, 6 }

c) A-B = { 8 , 10}
