What is the greatest perfect square that is less than 55?.
A. 49
B.
46
C. 36
D. 55 is a perfect square.

Step-by-step explanation:

-2x+5<3

-2x>3-5

-2x>-2

Divide both sides by -2

x>1

Answer:

-2x+5<3

-2x<-2

x<1

Answer:

3 ounces

Step-by-step explanation:

there are two ways that the answer to this question can be determined

Method 1

If the regular bottle  Holds 75% less in it, it means that the regular bottle holds 25%(100 - 75)

Ounces the regular bottle holds = 25% x 12

0.25 x 12 = 3

Method 2

Determine the value of 75%

75% x 12

0.75 x 12 = 9

Since the regular bottle  Holds 75% less in it, subtract the value of 75% from 12 ounces

12 - 9 = 3

Answer:

A

Step-by-step explanation:

expanding the bracket, we would have

-2x -18 = -x+1+2

-2x+x= 3 +18

-x=21

x=-21

Answer:

A

Step-by-step explanation:

−2(x+9)=−1(x+−1)+2

Use distributive property

-2x - 18 = -1x + 1 +2

-2x - 18 = -1x + 3

      +18         +18

-2x = -1x +21

+1x    +1x

___________

-x = 21

we need to have a positive x so multiply x by -1. -x times -1 = x

What we do on the left side has to happen to the right side too

So, 21 times -1 = -21

Therefore, x = -21

Answer:

[tex]y = - 2 \\ x = - 2[/tex]

Step-by-step explanation:

[tex] - 5x - 3y = 16 \: \: = > 1 \\ y = x = > 2[/tex]

Now you can write the 1st equation like this.

[tex] - 5x - 3y = 16 \\ x = y \\ so \: \: you \: \: \: can \: \: write \\ - 5y - 3y = 16 \: \: \: = > 3[/tex]

Now simply Solve the 3rd equation

[tex] - 5y - 3y = 16 \\ - 8y = 16 \\ \frac{ - 8y}{ - 8} = \frac{16}{ - 8} \\ y = - 2[/tex]

Now replace y as 2 in the 2nd equation like this

[tex]y = x \\ - 2 = - 2[/tex]

Now let's check whether the answer correct or wrong

[tex] - 5x - 3y = 16 \\ - 5 \times - 2 - 3 \times - 2 = 16 \\ 10 + 6 = 16 \\ 16 = 16[/tex]

Yes, the answer is correct

hope this helps you !!

Answer:

1 is the answer have a good day

Answer: Coupon B gives the lower price

The price of coupon B is  3.75 dollars   less than the price of coupon A.

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

Explanation:

15% off means she saves 15% of the original price.

15% of 95 = 0.15*95 = 14.25

Rachel saves $14.25 if she goes with coupon A.

We can see that coupon B gives the lower price because we have more in savings (since 18 is larger than 14.25).

If she goes with option A, then she spends 95-14.25 = 80.75 dollars. If she goes with option B, then she spends 95-18 = 77 dollars. Going with option B means she saves 80.75-77 = 3.75 dollars

Or you could note that 18-14.25 = 3.75 is another way to find out how much is saved when comparing the two coupons.

Answer:

c

Step-by-step explanation:

We are dividind how 100 can fit in 15 seconds

which is 100 /15

therefore when C when u tak it to the other side it divides 100 in 15

d×15=100

d=100/15

Answer:

[tex]\text{D. 36.64}[/tex]

Step-by-step explanation:

The Law of Sines is given by [tex]\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}[/tex] and works for any triangle.

Therefore, we have the proportion:

[tex]\frac{c}{\sin 41.5^{\circ}}=\frac{37}{\sin 42^{\circ}},\\\\c=\frac{37\sin 41.5^{\circ}}{\sin 42^{\circ}}=36.6399945706\approx \boxed{36.64}[/tex]

Answer:

50

Step-by-step explanation:

Given:

32 + (7 − 2) ⋅ 4 − 6/3

Using the acronym PEMDAS

P = parenthesis

E = Exponential

M = Multiplication

D = Division

A = Addition

S = Subtraction

32 + (7 − 2) ⋅ 4 − 6/3

= 32 + (5) • 4 - 6/3

= 32 + 20 - 6/3

= 32 + 20 - 2

= 52 - 2

= 50

Therefore,

32 + (7 − 2) ⋅ 4 − 6/3 = 50

Answer:

f^(-1)(x) = (x-b)/m  or  x/m - b/m

Step-by-step explanation:

f(x) = y = mx + b

To find the inverse function, interchange x and y and solve for y, i.e.

x = my + b

my = x-b

y = (x-b)/m = x/m - b/m

Let x be the hottest temperature.

Equation: x - (-35.67) = 148.98

So,

x - (-35.67) = 148.98

=> x + 35.67 = 148.98

=> x = 148.98 - 35.67

=> x = 113.31

Answer:

y = 3(x + 1)² - 7

Step-by-step explanation:

y = 3x² + 6x - 4

First, factor out the coefficient of the quadratic eq'n:

y = 3(x² + 2x - ⁴/₃)

Use the "complete the square" rule;

The "x² + 2x" should be rewritten as "(x + 1)² - 1", i.e. place into squared brackets x (without the power 2) and add half the coefficient of the x-term, you then need to subtract the square of the constant term in the squared brackets and then simplify:

y = 3((x + 1)² - 1 - ⁴/₃)

y = 3((x + 1)² - ⁷/₃)

Finally, multiply the 2 terms you end up with by the 3, factored out initially:

y = 3(x + 1)² - 7

Answer:

1 : 10

Step-by-step explanation:

Let :

Water = x

Milk = y

Purchase = 6.4 * y = 6.4y

Sales = 8(x + y)

Profit accrued = 37.5%

Sales = profit made from sales

8(x + y) = 6.4x * (100%+37.5%)

8(x + y) = 6.4x * 1.375

8x + 8y = 8.8x

8y = 8.8x - 8x

8y = 0.8x

y/x = 8/0.8

y/x = 10 / 1

y : x = 10 : 1

Step-by-step explanation:

Answer:

2x-y=8

(3x-y=17)*_1

2x-y=8

-3x+y=-17

#-x=-9, x=9 & y=-10

Answer:

x = 9  and y  = 10

Step-by-step explanation:

Subtract the second equation from 1 as in doing so the y will get cancelled as they are of the opposite sign.

2x - y = 8

-3x + y = -17

-----------------

- x = - 9

Therefore,

x = 9

Now we will add the value of x to any of the equation from the question.

2x - y = 8

2(9) - y = 8

18 - y = 8

Therefore,

y = 10

Step-by-step explanation:

3(x + 4) + 2 = 2 + 5(x – 4)

Step 1: distributive property

3(x + 4) + 2 = 2 + 5(x – 4)

3x + 12 + 2 = 2 + 5x - 20

Step 2: collect like terms

3x + 12 + 2 = 2 + 5x - 20

3x + 14 = 5x - 18

Step 3: Addition property of equality

3x + 14 = 5x - 18

3x + 14 + 18 = 5x - 18 + 18

3x + 32 = 5x

Step 4: subtraction property of equality

3x + 32 - 3x = 5x - 3x

32 = 2x

Step 5: division property of equality

32 = 2x

32/2 = 2x/2

16 = x

x = 16

Answer:

5

Step-by-step explanation:

In all right triangles, the tangent of an angle is equal to its opposite side divided by its adjacent side (neither of sides may be the hypotenuse). Thus, we have:

[tex]\tan 60^{\circ}=\frac{5\sqrt{3}}{y},\\y=\frac{5\sqrt{3}}{\tan 60^{\circ}}=\boxed{5}[/tex]

Answer:

250

Step-by-step explanation:

There is a 200 start up cost plus 50 per month

Cost = 200 + 50m  where m is the number of months

We have 1 month

Cost = 200 +50(1)

Cost = 250

Answer:

250
