Answers

Answer:

$79.670.

Step-by-step explanation:

Dado que María tiene en su libreta de ahorros un capital de $ 123.000,si deposita el día lunes la cantidad de $12.670, y el día miércoles por una urgencia, realiza un giro de $56.000, para determinar cuál es el nuevo capital que posee se debe realizar el siguiente cálculo:

123.000 + 12.670 - 56.000 = X

135.670 - 56.000 = X

79.670 = X

Así, el nuevo capital que María posee en su cuenta es de $79.670.

Without graphing, determine whether the system of linear equations has one solution, infinitely many solutions, or no solutions.

y=6x+2y=6x+2 and y=6x-4y=6x−4

Answers

Answer:

          The system has no solutions.

Step-by-step explanation:

y = 6x + 2     ⇒    6x - y = -2

y = 6x - 4      ⇒    6x - y = 4

a₁ = a₂ = 6  ,  b₁ = b₂ = -1 ,  c₁ = -2 , c₂ = 4

a₁ = a₂ = 6   and  b₁ = b₂ = -1  and  c₁ ≠ c₂  ⇒  NO SOLUTIONS

What is the measure of the smaller of two complementary angles if one angle is 4x and the other is 2x + 18?

Answers

Answer:

42°

Step-by-step explanation:

4x + 2x + 18 = 90        because they are complementary angles (add up to 90°)

reduce:

6x = 72

x = 12

one angle = 4(12) = 48°

other angle = 2(12) +18 = 42°

Joshua drove his car a distance of 321.7 miles, and it required 13.6 gallons of gasoline (petrol). How many liters of fuel will it take to go 100 kilometers?

Answers

Answer:

1005.68 litres

Step-by-step explanation:

Steps to answering this question

Convert miles to kilometers and gallons to litresThen divide the converted miles by the converted gallons Multiply the value gotten from the above step by 100 km

1 gallon = 3.78541 litres

13.6 gallons x 3.78541 = 51.48 litres

1 mile = 1.60934 km

321.7 miles x 1.60934 = 517.72 km

Litre needed per kilometer =  517.72 km / 51.48 = 10.06

Litres needed for 100 km = 100km x 10.06 = 1005.68 litres

In kite PQRS, m_OPO = 50° and m_ORO = 70°. Find m2PSR

Answers

Answer:

m<PSR = 60°

Step-by-step explanation:

Given:

m<OPQ = 50°

m<ORQ = 70°

Required:

m<PSR

Solution:

m<PQR + m<OPQ + m<ORQ = 180° (Sum of triangle)

m<PQR + 50 + 70 = 180 (Substitution)

m<PQR + 120 = 180

m<PQR = 180 - 120

m<PQR = 60°

One of the properties of a kite states that the angles where the unequal sides meets are congruent to each other. Therefore:

m<PSR = m<PQR

m<PSR = 60° (substitution)

Answer: 4

Step-by-step explanation:

First, we need to find the volume of the pyramid. The formula for its volume is pictured below. We know all the sides and dimensions of the pyramid, so that is why we are doing this first.

14 * 4 * 12 =  672

672 divided by 3 is 224. The volume of the pyramid is 224 in cubed.

Now, we need to find the area of the rectangular prism. We can use that and divide the volume of the pyramid with it. Doing so will give us the value of x.

8 * 7 = 56.

224 divided by 56 = 4

X equals 4.
