Answer:

58

Step-by-step explanation:

since the triangle has two sides of the same length (6.2cm), this means that it is a isosceles triangle, and that also means that the two angles at the base are the same (both will be 61 degrees)

then just use 180 minus the two angles and you will get x

Answer:

Step-by-step explanation:

Given that:

The investment amount in account = $ 320

The rate of interest is = 8.1% compounded quarterly

Compunded quarterly means  8.1% / 4  = 0.02025

The time period = t years

The objective is to write a function showing the value of the account after t years.

From compound interest , compounded monthly.

[tex]Amount = Principal * ( 1 + \dfrac{rate}{12*100})^{12*time}[/tex]

[tex]= $320 *(1 + \dfrac{0.02025}{12*100})^{12t}[/tex]

[tex]= 320*(1+ 1.6875*10^{-5})^{12t}[/tex]

[tex]= 320 * ( 1.000016875)^{12t}[/tex]

Thus; the function after t years [tex]= $320 * ( 1.000016875)^{12t}[/tex]

The percentage of growth per year is :

= (1 + 0.02025)^4 - 1

= 1.083493758 - 1

= 0.083493758

= 8.4 % (APY) yearly

Answer:

-x (2 x - 5) (3 x + 2)

Step-by-step explanation:

Factor the following:

-6 x^3 + 11 x^2 + 10 x

Factor -x out of -6 x^3 + 11 x^2 + 10 x:

-x (6 x^2 - 11 x - 10)

Factor the quadratic 6 x^2 - 11 x - 10. The coefficient of x^2 is 6 and the constant term is -10. The product of 6 and -10 is -60. The factors of -60 which sum to -11 are 4 and -15. So 6 x^2 - 11 x - 10 = 6 x^2 - 15 x + 4 x - 10 = 2 x (3 x + 2) - 5 (3 x + 2):

-x 2 x (3 x + 2) - 5 (3 x + 2)

Factor 3 x + 2 from 2 x (3 x + 2) - 5 (3 x + 2):

Answer:  -x (2 x - 5) (3 x + 2)

Step-by-step explanation:

In the right triangle PNO:

By definition:

cos(β) = adjacent/hypotenuse

Replacing with data and solving for NO:

cos(∠O) = NO/PO

2/5 = NO/100

NO = (2/5)*100

Answer:

x = -32/3

y =28/3

Step-by-step explanation:

2x + 4y = 16

-5x-4y = 16

Add the equations

2x + 4y = 16

-5x-4y = 16

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

-3x = 32

Divide each side by -3

x = -32/3

Now solve for y

2x+4y = 16

2(-32/3) +4y = 16

-64/3 +4y = 16

Multiply each side by 3 to get rid of the fractions

-64 +3*4y = 16*3

-64 + 12y = 48

Add 64 to each side

12y = 112

Divide by 12

12y/12 = 112/12

y =28/3

Answer:

First Part is C

The second part is 0,2,4

Step-by-step explanation:

Edge said so

The graph of the solution is option (C) [tex]x\geq -3[/tex] is the correct answer.

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is the condition of being unequal. It is used most often to compare two numbers on the number line by their size.

For the given situation,

The expression is [tex]-3x-3\leq 6[/tex].

The graph below shows the inequality of the expression.

The solution of the expression is

[tex]-3x-3\leq 6[/tex]

⇒ [tex]-3x\leq 6+3[/tex]

⇒ [tex]-3x\leq 9[/tex]

Divide both sides by -3. Then the inequality will also get changed.

⇒ [tex]\frac{-3}{-3}x\geq \frac{9}{-3}[/tex]

⇒ [tex]x\geq -3[/tex]

Hence we can conclude that the graph of the solution is option (C) [tex]x\geq -3[/tex] is the correct answer.

Answer:

The answer is explained below

Step-by-step explanation:

This is a word problem, therefore to solve it the statement have to be writing in form of an equation and then solved.

Let the number of fishes caught by Bryan's son be x fishes. Since Bryan caught as many fish as his son, Bryan caught x fishes

Let the number of fishes caught by Elton's son be y fishes. Since Elton caught three times as many fish as his son, Bryan caught 3y fishes

All together, they caught 25 fish

Therefore it can be represented by the equation:

x + x + y + 3y = 25

2x + 4y = 25

2x = 25 - 4y

x = (25 - 4y)/2

The number of fish caught by Bryan is half of the difference between the total fish caught and four times the number of fish caught by Elton son

Answer:

(4, -0.6)

Step-by-step explanation:

The table is:

x       Given      Predicted     Residual value

1         -1.6              -1.2                  0.4

2          2.2             1.5                   0.7

4          6.1              6.7                  -0.6

The points on the residual plot must be the pairs (x, residual value). This is:

(1, 0.4)

(2, 0.7)

(3, -0.2)

(4, -0.6)

Thus, the correct choice is the last one: (4, -0.6)

The point that would be on the residual plot of the data is (4, -0.6). See the explanation below.

A residual plot is a graph in which the residuals are displayed on the vertical axis and the explanatory variables is displayed on the horizontal axis.

From the analysis of the table attached, we have the following points on the residual plot:

(1, 0.4)

(2, 0.7)

(3, -0.2)

(4, -0.6)

Point on the residual plot must include the point on x and a residual value, hence, the correct answer is (4, -0.6).

Answer:

216 ft²

Step-by-step explanation:

For this question, first find the area of the outsides of the square walls.

Since the cube has side lengths of 6, we can simply find the area of each wall. Remember, for a square, A = s².

A = 6²

A = 36. This is the area for each side of the wall. Since she is painting 4 walls, we can multiply this by 4.

36 ×4 = 144.

To find the area of the ceiling, we will need to use the formula for the area of a triangle : A = 1/2(bh). The base in the figure would be 6, and the height is also 6.

A = 1/2(6 ·6)

A = 1/2 (36)

A = 18. Therefore, each part of the ceiling is 18. Since the base is a square shape, there are 4 triangles that make up the ceiling. Multiply this by 4, giving you:

18 × 4 = 72.

Add the two areas from the walls and the ceiling:

144 + 72 = 216 ft²

Answer:

Yes, they are similar. The scale factor is 5/3

Step-by-step explanation:

The longest to the shortest side of quadrilateral KLMJ are: JM, ML, KJ, LK

The longest to the shortest side of quadrilateral QPSR are: QP, PS, RQ, SR

If the two quadrilaterals are similar, the following proportion must be satisfied:

JM = k*QP

ML = k*PS

KJ = k*RQ

LK  = k*SR

where k is the scale factor. Solving for k and replacing with lengths:

k = 25/15 = 24/14.4 = 20/12 = 15/9 = 5/3

From the figure, we can also see that:

∠M ≅ ∠P

∠L ≅ ∠S

∠R ≅ ∠K

∠Q ≅ ∠J

Therefore, the two quadrilaterals are similar.

Answer:

-48 ÷ 12

Step-by-step explanation:

account balance changed over a year = -$48

In a year, there are 12 months. Above statement can also be written as

account balance changed in 12 months = -$48

we have to find monthly change, so we divide LHS and RHS by 12

account balance changed in 12 /12 months = -$48/12

Thus, account balance changed in 1 months = -$48/12

which is represented  option 4 i.e -48 ÷ 12
