Answer:

C: 147°

Step-by-step explanation:

Based on looking, the most appropriate answer should be C, which is 147°.

Solve the inequality as y < 2x-3.

Draw the line y=2x-3 as a dashed line.

Shade below the line.

Josh needs to follow the steps to draw the required inequality graph.

Inequality expressions are expressions that are not separated by an equal sign.

Given the inequality expression 4x - 2y > 6,

Dividing through by 2 will give:

4x/2 - 2y/2 > 6/2

2x - y > 3

Make y the subject of the formula

-y > -2x + 3

y < 2x -3

For Josh to plot the inequality graph of y < 2x - 3, he needs to follow the process;

Answer:

B

Step-by-step explanation:

The equivalent expression is [tex]16x^{8}[/tex]. So, the correct option is B.

Given:

The given expression is:

[tex]4x^2\sqrt{5x^4}3\sqrt{5x^8},x\neq 0[/tex]

To find:

The equivalent expression.

Explanation:

We have,

[tex]4x^2\sqrt{5x^4}3\sqrt{5x^8}[/tex]

On simplification, we get

[tex]=4x^2(x^2\sqrt{5})3(x^4\sqrt{5})[/tex]

[tex]=(4\times 3)(x^{2+2+4})(\sqrt{5}\times \sqrt{5})[/tex]

[tex]=12(x^{8})(5)[/tex]

[tex]=16x^{8}[/tex]

Therefore, the correct option is B.

Answer:

For the first triangle the missing sides are 7 and 7√2 For the second triangle,the missing sides are 13√3 and 13

Step-by-step explanation:

For the first triangle,

cos(45°)=7/hypotenuse

hypotenuse×cos45=7

hypotenuse×√2/2=7

hypotenuse=14/√2=7√2

We can now find the adjacent side using Pythagorean theorem,

√(7√2)²-7²=7

For the second triangle,

cos(30°)=adjacent/hypotenuse

but cos 30=√3/2

√3/2=adjacent/26(cross multiply and simplify)

26√3/2=13√3

To find the opposite length,

√(26)²-(13√3)²=13

Answer:

a=9

Step-by-step explanation:

a^2+b^2=c^2

a^2+5.6^2=10.6^2

a^2+ 31.36=112.36

-31.36           -31.36

a^2=81

a=[tex]\sqrt{81}[/tex]

a=9

Answer:

9in

Step-by-step explanation:

is a right triangle so you can use Pythagorean Th.

(10.6)²= (5.6)² + a², subtract (5.6)² from both sides

(10.6)²- (5.6)² =  a²

81 =a², squareroot both sides

√81= √a²

±9 = a we only consider the positive solution because we use it for measurements so a=9

Answer:

The inequality 2.50x>40.00 represents the number of lunches needed to be purchased for the monthly lunch pass to be a better deal.

Step-by-step explanation:

Given that:

Cost of each lunch = $2.50

Cost of monthly lunch pass = $40.00

Number of lunches = x

For making the monthly pass a better deal, the cost of lunches should be greater than the cost of monthly lunches, therefore

Cost of lunch * Number of lunches > Cost of monthly lunch pass

2.50x > 40.00

Hence,

The inequality 2.50x>40.00 represents the number of lunches needed to be purchased for the monthly lunch pass to be a better deal.

Answer:

2.50x > 40.00

$2.50 times a number of lunches is greater than $40.

Answer:

f(-3) = -16

Step-by-step explanation:

Given piecewise function is,

f(x) = 5x - 1       If x < -2

        x + 3       If x ≥ -2

We have to find the value of he function when x = -3

Since x = -3 is less than x = -2,

Piece of the function to be considered,

f(x) = 5x - 1

f(-3) = 5(-3) - 1

f(-3) = -16

Answer:

7/13

Step-by-step explanation:

Let's call x= numerator

We know that :

Denominator= x+6

And

(numerator +2)/(denominator +2) = 3/5

So

(x+2)/(x+6+2)=3/5

(x+2)/(x+8)=3/5

(x+2)*5=(x+8)*3

5x+10=3x+24

2x=14

x=7

In the end

Numerator= x =7

Denominator=x+6 = 13

So the original number is 7/13

Step-by-step explanation:

it's multiplied by 2 as you go to triangle 2

Answer:

x = 8

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{5}{10}[/tex] = [tex]\frac{4}{x}[/tex] ( cross- multiply )

5x = 40 ( divide both sides by 5 )

x = 8
