A coin collection contains d dimes and q quarters worth a total of $50.

Which equation models this information?

d + q = 50

10d + 25q = 50

0.1d + 0.25q = 50

0.01d + 0.25q = 50

Answers

Answer 1

Answer:

0.1d + 0.25q = 50

Step-by-step explanation:

dimes are worth 10 cents so it's 0.1 and d represents the unknown amount

quarters are worth 25 cents so it's 0.25 and q represents the unknown amount

Parallelogram P Q S R is shown. The length of P Q is (2 x + 5) centimeters and the length of R S is (4 x + 1) centimeters. In parallelogram PQSR, what is PQ? 2 cm 5 cm 6 cm 9 cm

Answers

Answer:

9cm

Step-by-step explanation:

Opposite sides of a parallelogram are parallel (congruent). This shows that

PQ = RS

2x+5 = 4x+1

2x-4x = 1-5

-2x = -4

x = -4/-2

x = 2

Get PQ

PQ = 2x+5

PQ = 2(2)+5

PQ = 4+5

PQ = 9cm

Answers

500cal=1lb
1000cal=2lbs
2x5=10
1000x5=5000
Answer: 10 banana splits

Answer: 5

Step-by-step explanation:

each banana split is equal to 2 lbs. therefore, to gain 10 lbs. you need to eat 5 banana splits.

500cal = 1 lb.

1000cal = 1 banana split

1 banana split = 2lbs.

to gain 10lbs, divide 10lbs by 2lbs = 5 banana splits

Under his cell phone plan, Parker pays a flat cost of $36.50 per month and $5 per gigabyte. He wants to keep his bill under $45 per month. Write and solve an inequality which can be used to determine gg, the number of gigabytes Parker can use while staying within his budget.

Answers

Answer:  Parker can use 1.7 gigabytes to stay within his budget.

Step-by-step explanation:

If Parker pays a  flat cost of $36.50 and has to pay $5 a month then we can represent it by the  36.50 + 5gg  where gg is the number of gigabytes.

If  he has to keep his bill under $45 , then 36.50 + 5gg has to be less than 45.

36.50 + 5gg < 45.   Now solve for gg

-36.50             36.50

   5gg < 8.5

  gg< 1.7

To find the size of each angle, divide the sum, 540º, by the number of angles in the pentagon.

540° ÷ 5 = 108° There are 108° in each interior angle of a regular pentagon.

The perpendicular bisectors of triangle RST intersect at K. Find KR

Answers

Answer:

Step-by-step explanation:

Remark

The diagram is a mess of lines; you have to guess where that 12 belongs. Just to make the question a bit more interesting, I'm going to say the 12 belongs to the perpendicular.

If that's true you can find KT using Pythagorus. KT and RT are equal. (SSS)

So, let's go.

Givens

1/2 of ST = 1/2 32 = 16

12 is the leg of the small triangle KT and the third point where the perpenduclar line meets ST.

Solution

KT^2 = 16^2 + 12^2

KT^2 = 256 + 144

KT^2 = 400

KT = sqrt(400)

KT = 20

RK = KT because parts of a congruent triangle = parts of the other triangle containing the line (KT) that you are trying to find the length of.

Question :

Two cargo ships spot a signal fire on a small island. The captains know they are 140 feet

away from each other and using angle measuring device they can determine the angle from

each of their ships to the signal fire. The angle at ship A is 82º and the angle at ship B is 78º.

How far is it from Ship B to the signal fire at point C?

Hint: Use Law of Sines:

140 it

A(48.9) b(400.4) C(405.3) D(673.4)

Answers

Answer:

C) 405.3 ft

Step-by-step explanation:

A triangle is a polygon with three angles and three sides. Types of triangle are scalene, isosceles, equilateral, right angled triangle.

Given a triangle with angles A, B, C and the corresponding sides directly opposite to the angles as a, b, c. The sine rule states that:

[tex]\frac{a}{sin(A)}= \frac{b}{sin(B)} =\frac{c}{sin(C)}[/tex]

In the triangle formed by point C, ship B and ship A, we have ∠A = 82°, ∠B = 78°, c = AB = 140 ft. Hence:

∠A + ∠B + ∠C = 180° (sum of angles in a triangle)

82 + 78 + ∠C = 180

∠C + 160 = 180

∠C = 20°

Using sine rule:

[tex]\frac{c}{sin(C)}=\frac{a}{sin(A)}\\\\\frac{140}{sin(20)}=\frac{a}{sin(82)}\\\\a= \frac{140*sin (82)}{sin(20)}\\\\a=405.3\ ft[/tex]

a =  distance from Ship B to the signal fire at point C
