**Answer 1**

**Answer:**

60 Tons

**Step-by-step explanation:**

36 divided by 6 equals 6. So that six is used for the for extra years

36+6+6+6+6

**Answer 2**

The **number **of tonnes of **carbon dioxide **released in 10 years will be 60 **tonnes**.

What is the solution to the equation?

The allocation of weights to the important **variables** that produce the calculation's optimum is referred to as a direct **consequence**.

A **ratio** is a group of sequentially ordered numbers a and b expressed as a/b, where b is **never equal **to zero. When two objects are equal, a statement is said to be **proportional**.

A typical car **releases** 36 tonnes of **carbon dioxide **and six years.

Let 'x' be the **amount **of carbon dioxide.

At a **constant **rate, the number of **tonnes **of carbon dioxide released in 10 **years **will be given as,

x / 10 = 36 / 6

**Simplify **the equation, then we have

x / 10 = 36 / 6

x / 10 = 6

x = 60 tons

The **number **of tonnes of **carbon dioxide **released in 10 years will be 60 **tonnes**.

If the sum of the greatest and smallest of 4 consecutive even integers equals 30, what is the sum of all four integers?

### Answers

**Answer:**

The sum of all four integers is 60.

**Step-by-step explanation:**

Let the integers be x, x + 2, x + 4, and x + 6.

x + x + 6 = 30

2x = 24

x = 12

So x + x + 2 + x + 4 + x + 6 = 4x + 12 = 60

### Answers

**Answer:**

y = - [tex]\frac{3}{5}[/tex] x + 1

**Step-by-step explanation:**

Parallel lines have equal slopes

Calculate m of CD using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = C(- 3, 4) and (x₂, y₂ ) = D(7, - 2)

m = [tex]\frac{-2-4}{7+3}[/tex] = [tex]\frac{-6}{10}[/tex] = - [tex]\frac{3}{5}[/tex] , thus

### Answers

**Answer:**

b = 1/4

**Step-by-step explanation:**

Take the given fractions : 3/2 and 7/4 and find a common denominator.

We will use **4** as a common denominator.

In order for the denominator of 3/2 to get to 4, you need to multiply by 2.

3 × 2 = 6 2 × 2 = 4

how do you solve for x when you have this problem below please explain !!

### Answers

**Answer:**

**The value of x is 16**

**Step-by-step explanation:**

We can clearly see in the diagram that a transversal is intersecting two parallel lines.

When a transversal intersects two parallel lines, eight angles are formed.

The angles which are in the same position on same side of each line intersected by the transversal, are called corresponding angles.

**Corresponding angles are congruent.**

So,

Angle 6x+4° and 100° will be congruent or equal

[tex]6x+4 = 100\\6x =100-4\\6x = 96\\\frac{6x}{6} = \frac{96}{6}\\x = 16[/tex]

Hence,

Select the correct answer. Which equation represents the vertical line passing through (1,-9)? A x=-9 B. X= 1 C. y=-9 D y=1 Reset

### Answers

**Answer:**

x = 1

**Step-by-step explanation:**

the vertical line is passing through only the x-axis and not the y axis. So the graph is a x = ? All you e have to to is to look for the x coordinate of the point the vertical line is passing through which is 1 and so the answer is x = 1.

**Please mark brainliest. Thanks!!!!**

**x=1** represents the **vertical line** passing through (1,-9) .

What is vertical line ?

A **vertical line** is a line, **parallel to y-axis** and goes straight, up and down, in a coordinate plane.

In a vertical line **x-coordinate** remain **constant**, only y-coordinate changes.

The vertical lines are **parallel to the y-axis** and are perpendicular to the **horizontal lines**. On a vertical line, all the points on the line have the **same x-coordinate**.

Here **x=1** is the only **vertical line** which passes through (1,-9) So **option B** is correct.

Given AXYZ = ARST.mZR=(6n+1). m _Y=108°, and m _Z=(91-4)', what is the value of n?

### Answers

**Answer:**

A

**Step-by-step explanation:**

Given that the triangles are congruent then corresponding angles are congruent, thus

∠ S = ∠ Y = 108°

∠ T = ∠ Z = 9n - 4

Given ∠ R = 6n + 1

The sum of the 3 angles in Δ RST = 180°

Sum the 3 angles and equate to 180, that is

6n + 1 + 108 + 9n - 4 = 180 , simplify

15n + 105 = 180 ( subtract 105 from both sides )

15n = 75 ( divide both sides by 15 )

n = 5 → A

**Which of the statements is not true?**

On the **graph**, we can see a **line **that contains points A, B, and C.

a shipping crate is a perfect cube with volume of 2,197 cubic feet. the ceiling of the warehouse is 14 feet high. will the crate fit in the warehouse explain why

### Answers

**Answer:**

**As the height of warehouse is greater than the height of crate, the crate will fit in the warehouse.**

**Step-by-step explanation:**

Given that

Volume of cube = V = 2197 cubic feet

Side of cube = a =?

Height of ware house = h = 14 feet

In order for the crate to fit in the warehouse the height of crate has to be less than the height of warehouse i.e. a<h

In order to check this we have to find the side/height of crate

So,

[tex]V = a^3\\2197 = a^3[/tex]

Taking cube root on both sides

[tex]\sqrt[3]{a^3} = \sqrt[3]{2197}\\\sqrt[3]{a^3} = \sqrt[3]{13^3}\\ a = 13\ feet[/tex]

**So the height of cube is 13 feet.**

Comparing the height of c and height of ware house we can conclude that

**Height of Warehouse > Height of crate**

**h>a**

**14>13**

**As the height of warehouse is greater than the height of crate, the crate will fit in the warehouse.**

After some snacks at McDonalds at Lower Bonifacio Street, Kristina drove 145 meters towards the three-way junction and turns right to reach a nearby church around Rimando Road. If the displacement between the church and McDonalds is 191.442 meters, how far did Kristina travel from the three-way junction to the church?

### Answers

**Answer:**

125 m

**Step-by-step explanation:**

The path of Kristina is in the shape of a right triangle where, the perpendicular is the path from the McDonalds to the three-way junction which is 145 m and the shortest distance between the McDonalds and the church is 191.442 m.

By Pythagoras theorem

[tex]145^2+x^2=191.442^2\\\Rightarrow x=\sqrt{191.442^2-145^2}\\\Rightarrow x=125\ \text{m}[/tex]

**Christina had to travel 125 m from the three-way junction to the church.**

The **distance** Kristina travelled from the three-way junction to the church is; *x = 125 meters*

We are told that she drove 145 meters towards the three way junction. She now turned right to reach a nearby church around rimando road.

This means that if the distance at which she turned right is x, then x is **perpendicular** to 145 m.

Now, we are told that the **displacement **between the church and McDonalds is 191.442 meters.

The displacement means the distance from the final position to the initial position. Thus, there will form a right angled triangle with **191.442 as the hypotenuse.**

Using **Pythagoras theorem**, we have;

**x² + 145² = 191.442²**

x² = 191.442² - 145²

x² = 15625.039364

x = √15625.039364

**x = 125 meters**
