Answer: 47, 74

Step-by-step explanation:

Let x = units digit

x – 3 = tens digit

Then the number is 10(x – 3) + x and the reversed number is 10(x) + (x – 3)

Equation

The reversed number plus the original number equal 121.

10(x) + (x – 3) + 10(x – 3) + x = 154

10x + x – 3 + 10x -30 + x = 121

22x – 33 = 121

22x = 154

x = 7 (units digit)

x – 3 = 4 (tens digit)

Answer

The number is (4 X 10) +7 or 47.

Perimeter ⇒ 33 ( units )

Step-by-step explanation:

As you can see, the points share a common y - value, so that they should be positioned with a horizontal distance among them;

[tex]Distance Among Points ( - 9, - 2 ), and ( - 2, - 2 ) , 9 + 2 = 11 units difference,\\[/tex]

Now if the difference is 11 units, we can determine the perimeter of this equilateral Δ assuming the sides are of equal length ( ≅ ) knowing that they do ∈ to an equilateral Δ;

[tex]Side 1 Length - 11 units,\\Side 2 Length - 11 units,\\Side 3 Length - 11 units,\\\\Perimeter = 11 * 3 = 33 units,\\\\Perimeter of Triangle PQR = 33 ( units )[/tex]

Answer:

The distance between the pair of points is 5 units.

Step-by-step explanation:

The first thing we must know in order to solve this problem is the distance formula.

[tex]Distance(d)=\sqrt{(x_{2}-x_{1} )^2+(y_{2}-y_{1})^2}[/tex]

We will use the coordinate point (2,0) for our (x₂,x₁) and the coordinate point (6,-3) for our (y₂,y₁). Now, let's plug in these numbers into our formula.

[tex]d=\sqrt{(6-2)^2+(-3-0)^2}[/tex]

[tex]d=\sqrt{(4)^2+(-3)^2}[/tex]

[tex]d=\sqrt{16+9}[/tex]

[tex]d=\sqrt{25}[/tex]

Answer:

C

Step-by-step explanation:

The new rate would be 3.75% when Peter's bank offered him a 4.85% interest rate for his mortgage. If he purchases 3 points.

A mortgage is an agreement between you and a lender that gives the lender the right to take your property if you fail to repay the money you've borrowed plus interest.

Mortgage loans are used to buy a home or to borrow money against the value of a home you already own.

Purchasing a point simply implies negotiating for a lower rate of interest, which involves paying 1% of the loan in lieu of 1% interest reduction.

A point implies a reduction in interest rate by 0.25% while 3 points would reduce the interest rate by 0.75%(0.25%*3)

New interest rate=4.5%-0.75%=3.75%

Answer B

One thing that gave it away was that we are dealing with a 30-60-90 triangle so in the final equation we should have (x=Any number) [tex]x\sqrt{3}[/tex] not square root two

The triangle ABC with ∠C as right angle , BC = 7 and ∠b = 30 degrees has AC as 7√3 / 3

A right angle triangle is a triangle that has one of its angle as 90 degrees. Therefore, the sides can be found using trigonometric ratios.

BC = 7 units

∠b = 30°

Hence, AC can be found as follows;

tan 30° = opposite / adjacent

tan 30 = AC / 7

cross multiply

AC = 7 tan 30

AC = 7 × 1 / √3

AC = 7 / √3

AC = 7√3 / 3

Answer:

15x + 10.

Step-by-step explanation:

To find the area of a rectangle, recall the formula is A = l × w. Therefore:

A = (3x + 2) (5)

Distribute the '5':

A = 15x + 10

Therefore, the area of the rectangle of 15x + 10.

Answer:

15x+10 units ^2

Step-by-step explanation:

The area of a rectangle can be found using:

A = l * w

The length of the rectangle is 3x+2 and the width is 5.

l=3x+2

w=5

Substitute these values into the formula.

A= 3x+2 *5

This can be rewritten as: (Commutative property of Multiplication)

A= 5* 3x+2

A= 5(3x+2)

Distribute the 5. Multiply each term inside the parentheses by the number outside the parentheses.

A= (5*3x) + (5*2)

A= 15x +10

A= 15x+10 units^2

The area of the rectangle is 15x+10 square units.

Answer:

Step-by-step explanation:

[tex]Distance=\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}} \\[/tex]

A(3,-2) ;  B(6,-2)

[tex]AB=\sqrt{(6-3)^{2}+(-2-[-2])^{2}}\\\\ =\sqrt{3^{2}+(-2+2)^{2}}\\\\=\sqrt{9+0}=\sqrt{9}\\\\[/tex]

B(6,-2) ;  C(6,5)

[tex]BC=\sqrt{(6-6)^{2}+(5-[-2])^{2}} \\\\=\sqrt{0+(5+2)^{2}}\\\\=\sqrt{(7)^{2}}\\[/tex]

BC = 7 units

Area of rectangle = length * width

                             = AB * BC

Answer:

x=15°

Step-by-step explanation:

Angles ∠2 and ∠4 are supplementary, so ∠2+∠4=180°

That equals to 2x+10+4x+80=180.

You can solve that equation to find what x is equal to.

2x+10+4x+80=180

6x+90=180

6x=90

Answer:

[tex]160^\circ[/tex] is the degrees value of [tex]\theta = \dfrac{8 \pi}{9}[/tex].

Step-by-step explanation:

We are given the following details about the angle [tex]\theta[/tex]:

[tex]\theta =\dfrac{8\pi}{9}\text{ radians}[/tex]

It is know that the relation between radians and degree units is as follows:

[tex]\pi \text{ radians} = 180 ^\circ[/tex]

We can use simply use unitary method to convert radian value of [tex]\theta[/tex] to degrees.

[tex]\pi \text{ radians} = 180 ^\circ[/tex]

[tex]\Rightarrow 1 \text { radian}= \dfrac{\pi}{180} ^\circ[/tex]

[tex]\Rightarrow \dfrac{8\pi}{9} \text{ radians} = \dfrac{180}{\pi} \times \dfrac{8\pi}{9} ^\circ\\\Rightarrow \dfrac{180 \times 8}{9}^\circ\\\Rightarrow 20 \times 8^\circ\\\Rightarrow 160 ^\circ[/tex]

Hence, [tex]\theta = 160^\circ[/tex]

Answer:

It costs $34 to buy a box of 64 markers.

Step-by-step explanation:

Check whether we are working with a direct proportion, in which case the comparison between the price and the number of markers would be the same.

$ 14  ÷  24  =  $0.58   and   $ 7 ÷  10  =  $ 0.70

The prices differ, so they are not directly proportional.

The reason is that both prices include the price of the box, which is the same. This can be thought of as the constant.

If you were to draw a graph of price (on the  y -axis) and number of markers (on the  x -axis) you would get a straight line where the  

y -intercept would be the price of the box and the slope would be the price of a marker. (rate of change of price)

Let's find the slope.

m = (y _2 − y _1 /x _2 − x _1)

m  =  ($14 −$ 7 /24− 10)  =  ($ 7 /14  markers)  =  $ 0.50 / marker

Therefore each marker costs  

$ 0.50  or  50 c

the price of  64  markers is:

64  ×  0.5 =  $ 32.00  ←  this is just the markers,

How much does the box cost? Consider  

$ 7  for  10  markers at  $ 0.50  each

$ 7  −  10  ×  $ 0.50  =  $ 7 −  $ 5  =  $ 2

The box itself costs  $2

The total cost of  64 markers in a box would be:

$ 2  +  $ 32 =  34#

Answer:

Center (0, 1)

Radius 1

x-intercept (0, 0)

y-intercept (0, 0), (0, 2)

Step-by-step explanation:

(1) A circle that has center (a, b) and radius r can have the equation as below:

(x - a)^2 + (y - b)^2 = r^2

Re-write the original equation: x^2 + (y - 1)^2 = 1, we have:

(x - 0)^2 + (y - 1)^2 = 1^2

=> The center of this circle: (a, b) = (0, 1) and the radius r = 1

(2) To find out the x-intercept, we substitute y = 0 into original equation.

=> x^2 + (0 - 1)^2 = 1

=> x^2 + 1 = 1

=> x^2 = 0

=> x = 0

=> x-intercept (0, 0)

(3) To find out the y-intercept, we substitute x = 0 into original equation.

=> 0^2 + (y - 1)^2 = 1

=> (y - 1)^2 = 1

=> y - 1 = -1 or y - 1 = 1

=> y = 0 or y = 2

=> y-intercept (0, 0) and (0, 2)
