4 gallons of paint cost a total $22.00. How much will 14 gallons cost? A. $60.50 B. $242.00 C. $82.00 D. $77.00

Answers

The answer is D. $77.00. To get the cost for a single gallon you divide $22 by 4 gallons you get $5.50. To get the cost for 14 gallons you multiply $5.50 by 14 and you get the answer $77.00.

1.) A ladder is leaning against the side so that the distance on the ground betweenthe base and the house is 7 feet.
If the ladder is 15 feet long, then what is the angle at which the ladder is leaning?

Answers

The angle at which the ladder is leaning is 62.18°.

What is trigonometry?

Trigonometry is the branch of mathematics that deals with calculating the angles of triangles or the lengths of their sides. It mainly concerned on the properties of right angled triangle.

For the given situation,

The length of the ladder = 15 feet

The distance between the house and the ladder base = 7 feet

The angle at which the ladder is leaning can be found by using trigonometric ratio, cos θ.

we know that, $cos$ θ = $(Base)/(Hypotenuse)$

The figure below shows the relationship between the sides.

⇒ $cos$ θ = $(7)/(15)$

⇒ θ = $cos^(-1)((7)/(15) )$

⇒ θ = $62.18$

Hence we can conclude that the angle at which the ladder is leaning is 62.18°.

Answer:

62.182°

Step-by-step explanation:

Using cos and sin you are able to find the height of the ladder from the bottom of the house to the place the top of the ladder is. You can do this by making a triangle. By using the lengths and angles already present you are able to find all angles of the triangle.

ACCORDING to the rate of electricity charge, the minimum charge up to 20 unit is Rs 80 and the cost per unit from 21 units to 250 units is Rs 7.30. How many units were consumed by Rs 1248?

Answers

Answer:

180

Step-by-step explanation:

let x = total units of electricity after 250 units

the total units of electricity consumed can be determined using the formula below

80 + 7.3x = 1248

7.3x = 1248 - 80

7.3x = 1168

divide both sides of the equation by 7.3

x = 1168 / 7.3

x = 160

total electricity consumed = 160 + 20 = 180

160

What two numbers multiply to 18 but add to get -5?

Answers

so this one has to be two negative numbers to get a positive number. so then you can think of what multipys to 18
-9*-2 wont work because -9+-2 gets you -11
-6*-3 wont work because -6+-3 gets negative nine
i dont think there is one honestly. ive sat here and tried them all
2 and 9 6 and 3 and 18 and 1

Final answer:

To find two numbers that multiply to 18 and add to -5, consider the factors of 18 and check which pair meets the conditions. The numbers that satisfy the given conditions are -9 and -2.

Explanation:

To find two numbers that multiply to 18 and add to -5, we can use the factoring method. By considering all the possible factors of 18, we can find the pair of numbers that satisfy the given conditions. The two numbers that meet these criteria are -9 and -2.(-9 * -2 = 18, -9 + -2 = -11)
