Answer:

Step-by-step explanation:

GIVEN:

To find the value of y, isolate it on one side of the equation.

2y-6-3y+5

Solutions:

First, add by 6 from both sides.

2y-6+6=3y+5+6

Solve.

Add the numbers from left to right.

5+6=11

2y=3y+11

Then, you subtract by 3y from both sides.

2y-3y=3y+11-3y

Solve.

-y=11

Divide by -1 from both sides.

-y/-1=11/-1

Solve.

Divide these numbers goes from left to right.

11/-1=-11

[tex]\Longrightarrow: \boxed{\sf{y=-11}}[/tex]

Answer:

The lateral surface area of a square pyramid is the sum of the areas of the side faces only, whereas the surface area is the lateral area + area of the base. The lateral area of a square pyramid = 2al (or) 2a√[(a 2 /4) + h 2]. To get the surface area, we need to add the area of the base (which is a 2) to each of these formulas.The surface area of a square pyramid = a 2 + 2al (or) a 2 + 2a[(a 2 /4) + h 2]. where, a = Length of the base (square) l = slant height; h = height of the pyramid.

Answer:

(D) 29 pounds 3 ounces

Step-by-step explanation:

1 pound = 16 ounces

Therefore 10 pounds = 16 * 10 = 160 ounces

160 + 7 = 167 ounces (first pile)

Total Weight of Newspapers = Weight of First Pile + Weight of Second Pile

= 167 + 148 = 315 ounces

As 16 ounces = 1 pound

1 ounce = 1/16 pound

315 ounces = (1/16) * 315 = 19.6875 pounds

1 pound = 16 ounces

0.6875 pounds = 16 * 0.6875 = 11

19 + 11 = 30 pounds, which is close to ans (D)

Step-by-step explanation:

Start by giving the points coordinate points assuming the origin is the bottom left:

Apply the formula for the distance between two points:

[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]d = \sqrt{(10-4)^2+(6-2)^2}[/tex]

Answer:

  144 ft³

Step-by-step explanation:

This "irregular shape" is a composite shape that can be considered to be any of these compositions:

The volume of any one of these blocks is the product of height, width, and depth. The above decompositions are evaluated here.

  V = HWD

  V = (2 ft)(3 ft)(6 ft) +(2 ft)(9 ft)(6 ft) = 36 ft³ + 108 ft³ = 144 ft³

__

  V = (4 ft)(3 ft)(6 ft) +(2 ft)(6 ft)(6 ft) = 72 ft³ +72 ft³ = 144 ft³

__

  V = (4 ft)(9 ft)(6 ft) -(2 ft)(6 ft)(6 ft) = 216 ft³ -72 ft³ = 144 ft³

Travis must use 144 ft³ of concrete to make the block.

Answer:

x = 14

Step-by-step explanation:

14x = 196

x = 196 ÷ 14

x = 14

[tex]14x - 196 = 0 \\ \\ \implies14x = 0 + 196 \\ \\ \implies 14x = 196 \\ \\ \implies \: x = \frac{196}{14} \\ \\ \implies \: x = 14[/tex]

Answer:

Answer A

Step-by-step explanation:

Approach 1

B, C, and D are wrong because angles 1 and 2 are congruent.

Therefore your answer of both being 60°

Approach 2

Let x = angle 1.

360/x = 6

x = 60°.

Therefore Angle 1 is 60°

An interior angle of a hexagon is 120°

Let y = angle 2.

y is half of 120°

So 120/y = 2

y = 60°

For an amount of 6250 Peso, Hank have the quantities of the following denominations: 2503 bills of 50 peso, 2498 bills of 200 peso and 1249 bills of 500 peso.

In this question we must translate the statement of the problem into mathematical expressions and then we must solve the resulting system. We need three equations that describe the quantities of 50 peso, 200 peso and 500 peso bills:

y = x - 5     (1)

0.5 · y = z    (2)

x + y + z = 6250     (3)

The solution of the system of linear equations is described below:

x = 2503, y = 2498, z = 1249

Combine the terms through trigonometric identity and simplify, this should be your answer(not the actual result of the problem, just the simplified expression).

Answer:

Step-by-step explanation:

The rule is generally to reduce anything that isn't a sin(theta) or cos(theta) down to those two.

Givens

Tan(a) = sin(a) / cos(a)

sin(2a) = 2 sin(a)*cos(a)

Solution

Tan(a)/Sin(2a) = sin(a) / cos(a) // 2 sin(a) * cos(a) / 1    Invert and multiply

Tan(a)/Sin(2a) = sin(a) / cos(a) * 2 sin(a) * cos(a)          Cancel and combine

Answer: Tan(a)/sin(2a)  = 1 / (2* cos^2(a))

The estimated value is given by the expected value. The estimated number of clownfish in the store that have fin rot will be 216.

Binomial distributions consist of n independent Bernoulli trials.

Nemo's fish store has 12 tanks of clownfish: each tank holds 30 fish.

He collects and inspects 5 fish from each tank and finds that 3 fish have fin rot

Then the estimated number of clownfish in the store that have fin rot.

The number of the clownfish in the store will be

n = 12 × 30

n= 360

Then the value of p will be

0.35

0.36(greatest)

Step-by-step explanation:

Okay, so first we need to have all of our numbers in the same category of variable. So first, we will convert 9/25 to a decimal.

To do that, we must divide 9 by 25 to get our answer of 0.36.

Now, we will convert the 33% to a decimal by dividing it by 100 to get 0.33

We now have our list, which should be ordered as:

Answer:

1. (10,-4)

2. 12

3. 108

Step-by-step explanation:

First find the cordinate by seing were the point lands on the graph

sense it is +10 right the x = 10, and it is 4 below the origin making it a negitive 4, so u get (10,-4)

The graph is measured 2 units per box and sence the sides are parallel to the axies you can count each square by 2, giving you the measuers of 12 units.

Now finally, The area of a triangle is A=1/2bh, we arlready have our base, and we just found our hight, so now we just have to plug it in.

A= 1/2 (12) (18)

12*18 = 216

A= 1/2 (216)

A= 108

And we are done!
