Answer:

The gradient of the line passing through the points (4·a, -a) and (6·a, 5·a) is 3

Step-by-step explanation:

The gradient of a (straight) line given the 'x' and 'y' coordinates of two points on the line, (x₁, y₁), and (x₂, y₂) can be found using the following formula;

[tex]The \ gradient \ of \ a \ line, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

The coordinates of two points on the given line are;

(4·a, -a), and (6·a, 5·a)

Therefore, we get;

[tex]The \ gradient \ of \ the \ line =\dfrac{5\cdot a-(-a)}{6 \cdot a-4 \cdot a} = \dfrac{6\cdot a}{2 \cdot a} = 3[/tex]

The gradient of the line = 3.

Answer:

220

Step-by-step explanation:

Multiply 15 times 10 =150

150+70=220

Hope this helps :)

==========================================================

Explanation:

After 10 weeks, he'll deposit a total of 15*10 = 150 dollars on top of the $70 already in the account. This means the grand total is 150+70 = 220 dollars

If you need to use algebra, then an algebraic expression you can use is 70+15x where x is the number of weeks. Replace x with 10 and you'll end up with 70+15*10 = 70+150 = 220. It's effectively the same idea and steps as the previous paragraph, but now we're involving a variable.

Answer:

Answer will be 5890 square feet. Step-by-step explanation: An individual head of a sprinkler system covers a circular area of grass with a radius of 25 feet. Now 3A = 3×π×625 feet²= 3×3.14×625 = 5887.5 ≈ 5890 square feet.

3. 45

Answer:

A = 60 and B = 30  

Now, A + B = 60 + 30 = 90  

Also, A – B = 60 – 30 = 30  

sin (A + B) = sin 90 = 1  

sin A cos B + cos A sin B = sin 60 cos 30 + cos 60 sin 30

Answer:

168 sq inches

Step-by-step explanation:

SA = 2(1.5x6) + 2(1.5x10) + 2(6x10)

= 2(9) + 2(15) + 2(60)

= 18+30+120

= 168 sq inches

Answer:

Cost of five blouses = $145

Step-by-step explanation:

Let

x = cost of blouse

y = cost of skirt

15x + 2y = 505 (1)

5x + 2y = 215 (2)

Subtract (2) from (1) to eliminate y

15x - 5x = 505 - 215

10x = 290

x = 290/10

x = 29

Substitute x = 29 into (2)

5x + 2y = 215 (2)

5(29) + 2y = 215

145 + 2y = 215

2y = 215 - 145

2y = 70

y = 70/2

y = 35

x = cost of blouse = $29

y = cost of skirt = $35

How much do 5 such blouses cost?

cost of a blouse = $29

Cost of five blouses = $29 × 5

= $145

Cost of five blouses = $145

Answer:

[tex]n = 5[/tex]

Step-by-step explanation:

Given

[tex]2(n+1)! + 6n! = 3(n+1)![/tex]

Required

Find n

Simplify (n + 1)!

[tex]2(n+1)*n! + 6n! = 3(n+1)*n![/tex]

Factorize

[tex]n![2(n+1) + 6] = 3(n+1)*n![/tex]

Divide both sides by n!

[tex]2(n+1) + 6 = 3(n+1)[/tex]

Open brackets

[tex]2n + 2 + 6 = 3n + 3[/tex]

[tex]2n + 8 = 3n + 3[/tex]

Collect like terms

[tex]2n - 3n = 3 -8[/tex]

[tex]-n =-5[/tex]

Multiply both sides by -1

[tex]n = 5[/tex]

Complete question :

A city has a higher elevation than Coachella, CA.

Coachella's elevation is 22 feet below sea level (-22 ft.)

Select the four numbers that could represent the city’s elevation. Be prepared to explain your reasoning.

Group of answer choices

-11 feet

4 feet

-8 feet

-35 feet

0 feet

-44 feet

Answer:

- 11 feets

4 feets

0 feets

-8 feets

Step-by-step explanation:

Kindly note, that, elevation below sea level should be represented with negative Integers:

Coachella's elevation = - 22 feets

SINCE it is a stated that city A has a higher elevation than Coachella ;

Therefore, Elevation of city A is greater than - 22 feets

Therefore x from the options possible elevation of city A are :

All values in the option greater than - 22; The numbers include :

-8 feets, 0 feets, - 11 fees, 4 feets

Responder:

13 gols

Explicação passo a passo:

Dado que :

Taxa de conversão = 65%

Número de fotos tiradas = 20

O número estimado de gols marcados será:

O produto da taxa de conversão e o número de fotos tiradas;

Número de fotos tiradas * taxa de conversão

20 * 65%

20 * 0,65

= 13 gols

Portanto, número estimado de gols marcados = 13 gols

Ok...so we have this........

y = ax2 + 4      ....... and we need to find "a"

So we have

-1 = a(-10)2 + 4

-5 = a (100)

(-1/20) = a      .......  So we have ..........

y = (-1/20)(x- 0)2 + 4   or just  (-1/20)x2 + 4

Note that this parabola opens downward...That makes sense since the vertex is above the x axis and the parabola passes through a point below the x axis.

Answer:

x = 70°, y = 110° , z = 85°

Step-by-step explanation:

∠ BEA and ∠ CDA are corresponding angles and congruent , then

x = 70°

x and y are adjacent angles and sum to 180°

x + y = 180°

70° + y = 180° ( subtract 70° from both sides )

y = 110°

∠ ABE and ∠ ACD are corresponding angles and congruent , then

z = 85°
