Answer:

m∠NSR = 113°

m∠RSP = 67°

Step-by-step explanation:

Angle formed between the intersecting chords is one half the sum of the measures of the arcs intercepted by the angles.

m∠NSR = [tex]\frac{1}{2}[\text{arc}(NR)+\text{arc}(PQ)][/tex]

             = [tex]\frac{1}{2}(176+50)[/tex]

             = 113°

Since, m∠NSR + m∠RSP = 180° [Linear pair of angles are supplementary]

113° + m∠RSP = 180°

m∠RSP = 180° - 113°

             = 67°

Savings in March: $60

Savings in April: $60 + 150% of $60=$60 +$90=$150

Answer:

9 times larger

Step-by-step explanation:

The volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius, h the height )

Ir is tripled , that is r = 3r , then

V = π × (3r)² h = 9πr²h

That is the volume is now 9 times larger

= 20.83

Therefore the time required to reach 825 ministers

= 825×20.8

= 17,160

Hence the time needed is 17, 160

Answer:

5.6 miles per gallon

Step-by-step explanation:

Equation for Mrs Sanchez: y = 36x

The rate of change = miles/gallon for Mrs Sanchez = 36 miles/gallon

Let's find the rate of change for Mr White:

Rate of change = change in y/change in x

Using two pairs of values form the table given, (2.5, 76) and (5, 152),

Rate of change = (152 - 76)/(5 - 2.5) = 76/2.5

Rate of change = miles/gallon = 30.4 miles/gallon

The difference between the miles per gallon of Mrs Sanchez and Mr White = 36 - 30.4 = 5.6 miles per gallon.

Therefore, Mrs Sanchez gets 5.6 miles per gallon than Me White

Answer:

452.16 cm³

Step-by-step explanation:

I assume the shape of the volcano is a cone.

V = (1/3)πr²h

r = d/2 = 12 in./2 = 6 in.

V = (1/3)(3.14)(6 in.)²(12 in.)

V = 452.16 in.²

Answer:

Step-by-step explanation:

Radius r = 6 inches

Height h = 12 inches

volume of cone = πr²h/3 ≈ 3.14∙6²∙12 = 1,356.48 in³

Answer:

Step-by-step explanation:

The situation that can be modeled by the expression -3/4 x 2/5  is:

Abdi owes Kim 3/4 of a dollar. He pays her 2/5 of how much he owes.

The expression -3/4 x 2/5 gives us the fraction of a dollar that Kim receives from Abdi, which is -3/10 of a dollar.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The expression -3/4 x 2/5 means that we multiply -3/4 by 2/5.

Multiplying two fractions involves multiplying their numerators together and their denominators together. So,

-3/4 x 2/5 = (-3 x 2) / (4 x 5) = -6/20 = -3/10

Therefore,

The situation that can be modeled by the expression -3/4 x 2/5  is:

Abdi owes Kim 3/4 of a dollar. He pays her 2/5 of how much he owes.

The expression -3/4 x 2/5 gives us the fraction of a dollar that Kim receives from Abdi, which is -3/10 of a dollar.

The statement which is true of the right triangles ABC and DEF is Area of ABC is greater than area of DEF.

Right angled triangle are those triangle for which one of the angle is 90 degrees.

Given two right angled triangles, ABC and DEF.

Area of a triangle = 1/2 × base × height

Area of ΔABC = 1/2 × 14 × 6

                        = 42 square units

Base of ΔDEF = √(7² + 4²) = √65

Height of ΔDEF = √(5² + 8²) = √89

Area of ΔDEF = 1/2 × √65 × √89

                       = 38.03 square units

Hence the correct option is Area of ABC is greater than area of DEF.

Answer:

Total interest to be paid: $210

Total amount to be repaid: $3,710

Step-by-step explanation:

You can ignore the monthly payment for this problem.

For simple interest, the formula is I = PRT where I = interest earned, P = principal amount borrowed/deposited, R = rate as a decimal, and T = time in years.

I = (3,500)(0.06)(1)

I = 210

Then add that to the amount borrowed ($3,500) and you're done.

3,500 + 210 = $3,710
