Step-by-step explanation:

45.6*1.14

Answer:

The least common multiple, but you can use the greatest common factor, but at the end you have to simplify for it to be correct. 1 3/30

Step-by-step explanation: 4/15+5/6

Change 15 into a 30 by multiplying 2 to both sides.

Change 6 into a 30 by multiplying 5 to both sides.

so the new fractions are 8/30+25/30=33/30

The final fraction is 1 3/30.

Answer: C

Step-by-step explanation:

You can write each term into a fraction.

[tex]\sqrt[5]{x^4}[/tex] becomes [tex]x^4^/^5[/tex]

When you multiply 2 terms with the same base, you add the exponents.

[tex]x^4^/^5*x^4^/^5=x^4^/^5^+^4^/^5=x^8^/^5[/tex]

[tex]x^8^/^5[/tex] is also the same as [tex]x\sqrt[5]{x^3}[/tex]

You get this because [tex]\sqrt[5]{x^8} =\sqrt[5]{x*x*x*x*x*x*x*x}[/tex]. When you pull out 5 os x, you are left with x³ on the inside.

Answer:

y = 4

Step-by-step explanation:

We have,

5x + 3y = 12 ....(1)

and

-5x + 4y = 16 ....(2)

Adding equation (1) and (2),

0 + 7y = 28

or

7y = 28

Dividing both sides by 7,

y = 4

So, the value of y = 4.

Answer:

B. Figure B

Step-by-step explanation:

We have the phrase "If it is not warm, then it is not hot".

Chronologically and logically, it has to not be warm in order to not be hot. "Not warm" will have to encompass "not hot". Therefore, choice B is correct as the diagram shows "not warm" encompassing "not hot".

Answer:

The Hotel charge without tax in first city is $3500 and The hotel charge before tax in the second city is 2000

Step-by-step explanation:

Let x be the hotel charge without tax in first city

We are given that The hotel charge before tax in the second city was $1500 lower than in the first.

So, Hotel  charge without tax in second city =x-1500

Tax% in first city = 10%

So, tax in first city = 0.1x

Tax% in second city =5%

So, tax in second city = 0.05(x-1500)

We are given that The total hotel tax paid for the two cities was $600.

So,0.1x+0.05(x-1500)=600

0.1x+0.05x+75=600

0.15x=600-75

[tex]x=\frac{600-75}{0.15}[/tex]

x=3500

Hotel charge without tax in first city = $3500

The hotel charge before tax in the second city =x-1500=3500-1500=2000

Hence The Hotel charge without tax in first city is $3500 and The hotel charge before tax in the second city is 2000

1) 4x + 9 = 2x - 6

Subtract 9 from both sides

4x = 2x - 15

Subtract 2x from both sides

2x = -15

Divide both sides by 2:

x = -15/2 or -7.5

2) 2(x - 5) = 5x + 23

Expand the brackets:

2x - 10 = 5x + 23

Subtract 23 from both sides

2x - 33 = 5x

Subtract 2x from both sides

3x = -33

Divide both sides by 3

x = -11

3) 7x + 3 = 2x + 13

Minus 3 from both sides

7x = 2x + 10

Subtract 2x from both sides

5x = 10

Divide both sides by 5

x = 2

Answer:

B. $185,600

Step-by-step explanation:

80/20 mortgage means pay 20% down payment and 80% finance amount of home value.

Home value = $232,000

Now, we need to find finance amount from this hone value of $232,000

Let's calculate the 80% of $232,000 as finance amount;

Finance amount = 80% of 232000

Finance amount  = 0.80 x 232000

Finance amount = 185,600

Step-by-step explanation:

Answer:

The value of x is 12.

Step-by-step explanation:

Given that the area of triangle formula is A = 1/2×b×h where b represents base which is the x and h is height, 10 inches. So you have to substitute the following values into the formula :

[tex]area = \frac{1}{2} \times base \times height[/tex]

Let area = 60,

Let base = x,

Let height = 10,

[tex]60 = \frac{1}{2} \times x \times 10[/tex]

[tex]60 = 5 \times x[/tex]

[tex]5x = 60[/tex]

[tex]x = 12 \: inches[/tex]

Answer:

12 inches

Step-by-step explanation:

The area of a triangle can be found using the following formula.

a=(b*h)/2

We know that the triangle has an area of 60 inches squared. We also can see from the picture that the height is 10 inches, and the base is x inches.

a=60 inches^2

b= x inches

h= 10 inches

Substitute these values into the formula

60=(x*10)/2

Now, solve for x. To do this, get x alone. Perform the opposite of what is being done to the equation. Remember to perform everything to both sides of the equation.

x*10 is being divided by 2. The opposite of division is multiplication, so multiply both sides by 2.

2(60)=(x*10/2)2

2(60)=x*10

120=x*10

x is being multiplied by 10. The opposite of multiplication is division. Divide both sides by 10.

120/10=x*10/10

120/10=x

12=x

The base, or x, is 12 inches.

Step-by-step explanation:

Firstly note that the graph is shifted up 2 units, as it starts at positive 2, when it should start at 0.

That only leaves choices 1 and 2

However, since we know its flipped, we can easily rule out number 2, as number 2 wouldn't be a real number(sqrt of negatives)

That leaves answer choice 1

The correct option is y = -[tex]\sqrt{x}[/tex] +2

A transformation is a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system.

Given that, the graph of y= √x is transformed as shown in the graph.

That only leaves choices 1 and 2

Answer:

B.

Step-by-step explanation:

(x-1)2+(y+2)2=4.

because the equation is shown in the graph

the equation of the circle with a center at (-1, 2) and a radius of 2 is:

(x + 1)² + (y - 2)² = 4

From graph er can see that center of circle is (-1,2) and radius is 2

The equation of a circle with its center at point (h, k) and radius r is given by:

(x - h)² + (y - k)² = r²

In this case, the center of the circle is (-1, 2), and the radius is 2. Plugging these values into the equation, we have:

(x - (-1))² + (y - 2)² = 2²

Simplifying further:

(x + 1)² + (y - 2)² = 4

Expanding the square terms:

x² + 2x + 1 + y² - 4y + 4 = 4

Combining like terms:

x² + y² + 2x - 4y + 1 + 4 - 4 = 0

Simplifying:

x² + y² + 2x - 4y + 1 = 0

Therefore, the equation of the circle with a center at (-1, 2) and a radius of 2 is:

(x + 1)² + (y - 2)² = 4

Answer:

a)The constant of proportionality is 6.

b)The equation for this relationship is y=6x.

Step-by-step explanation:

a) 6/1=6

b)if apples is "x" and slices is "y," substitute y for 6 and x for 1

so 6=6(1) which is y=6x

The required constant of proportionality is 6 and the equation for this relationship is y=6x.

A table of data is given which describe the relationship between number of apples and number of slices. Blank space in statement to be filled.

The equation is a function of the relation between two or more values contains equal sign.

Here, from table the equation can be calculated as
Number of apples(x) is directly proportional to the number of slices(y). i.e.
y ∝ x
Now,
y=kx  ----(1)  (where k is proportionality constant)
for 1 apple the number of slices is 6 so,
6 = k*1
k = 6
Put k is equal to 6 in the equation (1).
y = 6x.

Thus, the required constant of proportionality is 6 and the equation for this relationship is y=6x.

Answer:

The area of rectangle A is length x breadth

= 3x5

= 15 units^2

The area of square B is side x side

= 3x3

= 9 units^2

Therefore,

The area of the rectangle is not double of the area of the square because 9x2 is not equal to 15. Steven isn't correct.

Answer:

a) Steven is incorrect.

b) Steven is incorrect, because he claims that, in other words, 15 units squared = 18 units squared. 18 > 15, so the statement that 15 = 18 is false. 15 does not equal 18.

Step-by-step explanation: Steven claims that the area of rectangle A is double the area of square B. The area of rectangle A is 15 units squared, because you get a product of 15 when you multiply the side lengths 5 and 3. The area of square B is 9 units squared, because you get a product of 9 when you multiply the side lengths 3 and 3. In other words, Steven is claiming that the area of rectangle A is not 15 units squared, but 18 units squared (this is double the area of square B, as 18 is the product of 9 and 2), and that statement is false, because we know that 18 > 15. Therefore, 18 cannot equal 15; the figure that is made from the value of double the area of square B (18 units squared) is larger than rectangle A (15 units squared) - this reinforces the fact that 18 > 15, and hence cannot be equal to 15.
