Answer:

  2 1/2 rolls

Step-by-step explanation:

rolls : walls = (1/2) : (1/10) = ? : (1/2) = 5/2 : 1/2 (multiply by 5, since 1/2 = 5/10)

It takes 5/2 rolls = 2 1/2 rolls to cover half the wall.

Answer:

[tex]2\frac{1}{2}[/tex] rolls of the wallpaper will cover half the wall

The correct option is (b) 2 1/2

Step-by-step explanation:

To determine the number of rolls of wallpaper that are needed to cover half (1/2) the wall,

From the question,

One-half of a roll of wallpaper covers 1/10th of a wall.

Hence, we are to determine the number of rolls of wallpaper that are needed to cover 5/10th of the wall. (NOTE: 5/10th of the wall = 1/2 the wall)

Now,

First, we will find the part of the wall that will be covered by one roll of the wallpaper

If one-half of the roll of wallpaper covers 1/10th of the wall.

Then, one roll (two halves) will cover 2 × 1/10th of the wall

= 1/5th of the wall

Hence one roll will cover 1/5th of the wall

Now, for the number of rolls that will cover half (1/2) the wall

If one roll of the wallpaper covers 1/5th of the wall

Then, [tex]x[/tex] rolls of the wallpaper will cover 1/2 of the wall

[tex]x =\frac{1/2 \times 1}{1/5}[/tex]

[tex]x =\frac{5}{2}[/tex]

[tex]x =2\frac{1}{2}[/tex]

Hence, [tex]2\frac{1}{2}[/tex] rolls of the wallpaper will cover half the wall

HAVE A GREAT DAY (:

Answer:

-6/7

Step-by-step explanation:

since both fractions have a common denominator (bottom part of fraction) you would end up subtracting 4-10 which would give you a -6. the denominator stays 7 so you end up with -6/7

Answer:

Seven days

Step-by-step explanation:

From the information given, you know that you drink in a day 1.25 cups of the tea in the morning morning and 1.5 cups of the tea in the evening which is equal to:

1.25+1.5=2.75 cups a day

Now that you know the amount of cups that you drink in a day, you can divide  the amount of cups in the pitcher by the amount of cups you drink in a day:

19.25/2.75= 7

According to this, the answer is that you will run out of iced tea after seven days.

Answer:

[tex]14^{2}[/tex] [tex]or 196[/tex]

Step-by-step explanation:

[tex]14^{6}[/tex] ÷ [tex]14^{4}[/tex]

all you have to do it subtract

[tex]14^{6} - 14^{4}[/tex]

=

[tex]14^{2}[/tex]

which is equivalent as 196.

to solve [tex]14^{2}[/tex], it's just

14 × 14 = 196

1       2

Answer:

(1, 28 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ]

here (x₁, y₁ ) = G(- 2, 46) and (x₂, y₂ ) = L(4, 10), thus

midpoint = ([tex]\frac{-2+4}{2}[/tex] , [tex]\frac{46+10}{2}[/tex] ) = ([tex]\frac{2}{2}[/tex] , [tex]\frac{56}2}[/tex] ) = (1, 28 )

We just take the square root of 16384.

√16384 = 128

128^2 = 16384

Answer:

13

Step-by-step explanation:

Applying the definition of the diagonals of an isosceles trapezoid, the value of x is: C. 13.

An isosceles trapezoid has two congruent legs and two diagonals that are congruent.

Given:

Thus:

SD = LG

Substitute

8x - 5 = 6x + 21

Combine like terms and find x

8x - 6x = 5 + 21

2x = 26

x = 26/2

x = 13

Thus, applying the definition of the diagonals of an isosceles trapezoid, the value of x is: C. 13.

Answer:

Step-by-step explanation:

In math, a multiple is the product of any quantity and an integer. In other words, for the quantities a and b, we say that b is a multiple of a if b = na for some integer n, which is called the multiplier. If a is not zero, this is equivalent to saying that b/a is an integer.

Answer:

[tex]\displaystyle r=\frac{3t}{t-1}[/tex]

Step-by-step explanation:

We are given the formula:

[tex]\displaystyle t=\frac{r}{r-3}[/tex]

And we are asked to make r the subject of the formula.

We can multiply both sides by r - 3. This reduces the denominator on the right-hand side:  

[tex]t(r-3)=r[/tex]

Distribute:

[tex]rt-3t=r[/tex]

Subtracting rt from both sides yields:

[tex]-3t=r-rt[/tex]

Factoring:

[tex]-3t=r(1-t)[/tex]

Divide and simplify:

[tex]\displaystyle \begin{aligned} r & = \frac{-3t}{1-t} \\ \\ & = \frac{3t}{t-1}\end{aligned}[/tex]

In conclusion:

[tex]\displaystyle r=\frac{3t}{t-1}[/tex]

Answer:

Step-by-step explanation:

x^4+6x^2-27=0

The two factors you need to use for 27 is 9 and 3.

Since the middle term must be plus then the 9 is also plus.

(x^2 + 9)(x^2 - 3)

x^2  + 9 can't be factored in the real number system.

x^2 - 3 = 0

(x + sqrt(3))(x^2 - sqrt(3))

The full factoring answer would be

(x^2+9)(x + sqrt(3))(x^2 - sqrt(3))

Perpendicular lines have opposite reciprocal slopes.

y = 1/4x - 10 is our original equation.

If we flip the slope and change the sign, we get -4

Answer:

[tex]y=\frac{3}{2}x-\frac{15}{2}[/tex]

Step-by-step explanation:

Use the point-slope formula [tex]y-y_{1}=m(x-x_{1})[/tex]

First you have to find m with the formula [tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

[tex]m = \frac{9 - 6}{11 - 9} = \frac{3}{2}[/tex]

Choose whichever point you want as [tex](x_{1}, y_{1})[/tex], in this case I'll choose [tex](9, 6)[/tex]

[tex]y - y_{1} = m(x - x_{1})\\y - 6 = \frac{3}{2} (x - 9)\\y - 6 = \frac{3}{2}x - \frac{27}{2} \\y = \frac{3}{2}x - \frac{27}{2} + 6\\y = \frac{3}{2}x - \frac{15}{2}[/tex]

a =80-5/5

a=75/5

a =15 ans

Answer:

if there was a 15% discount, then you paid 75% of the original price. Since we don't know the orginal price, we will assign it the variable x. Change 75% to a decimal. The equation would be:

.75x = 208.25 To get the variable by itself, divide each side by .75

.75x/.75= 208.25/.75

x = 277.6

The original price of the suit was $277.6
