3400 km is decreasing at a rate of 6.5% each year so after 7 years how much is left

Answer:

p=3

Step-by-step explanation:

9p+14=2p+35

Subtract 2p from each side

9p-2p+14=2p-2p+35

7p +14 = 35

Subtract 14 from each side

7p +14-14 = 35-14

7p = 21

Divide by 7

7p/7= 21/7

p=3

[tex]p = 3[/tex] ✅

Step-by-step explanation:

[tex]9p +14 = 2 p + 35 \\ ⇢ 9p - 2p = 35 - 14 \\ ⇢ 7p = 21 \\ ⇢ p = \frac{21}{7} \\ ⇢ p = 3[/tex]

To verify:-

[tex]9p + 14 = 2p + 35 \\ ⇢ 9 \times 3 + 14 = 2 \times 3 + 35 \\ ⇢ 27 + 14 = 6 + 35 \\ ⇢ 41 = 41 \\ ⇢ L.H.S.=R. H. S[/tex]

Hence verified.

Answer:

Unit price of roast beef = $6.86

Step-by-step explanation:

Given:

Cost of [tex]1\frac{3}{4}[/tex] pound package of roast beef = $12

Find:

Unit price of roast beef

Computation:

Unit price of roast beef  = Cost of 1 pound package of roast beef

[tex]1\frac{3}{4}[/tex] pound package of roast beef = 7 / 4 = 1.75 pound package of roast beef

Cost of 1 pound package of roast beef = Total cost / Total mass

Cost of 1 pound package of roast beef = 12 / 1.75

Cost of 1 pound package of roast beef = 6.857

Unit price of roast beef = $6.86

Answer:

25 km

Step-by-step explanation:

[tex]\frac{5}{25} :\frac{y}{125}[/tex]

y · 25 = 5 · 125

25y = 625

25y ÷ 25 = 625 ÷ 25

y = 25

Answer:

a) 1/2

b) 6/100

c)1/4

I'll explain how I got these answers later.

Answer:

Step-by-step explanation:

Total highlighters = 10

A : favourable cases / total cases  = 5/10 = 1/2

B : favourable cases/ total cases * favourable cases/ new total cases

2/10 * 3/9 = 1/5 * 1/3 = 1/15

C : favourable cases/ total cases * favourable cases/ new total cases

5/10 * 4/9 = 1/2 * 4/9 = 4/18

Answer:

1.36

total cans =11

the prob. of drawing orange juice can= 4/11

the prob of drawing apple juice can= 7/11

the prob of drawing any of the juice= 4/11 + 7/11

= 15/11

= 1.36

Answer: The slope between these two is 3.5

Answer:

Solpe=4.5

Step-by-step explanation:

Sorry if I’m wrong, but I think I got it.

So the formula for slope is    y2-y1/x2-x1  

In (-3,-2) )-7,-16),  -3 is x1, -2 is y1, -7 is x2, and -16 is y2.

Now, you need to fill in the formula with these numbers.

-16-2/-7- - 3

-16-2 is -18

-7- - 3 is -4 (two negatives make a positive)

This makes -18/-4. Divide this to get 4.5.

5x = 25

x = 5

Answer: $11.25

Step-by-step explanation:

Since the sneakers were on sale for 15% less, the amount she bought them will be:

= (100% - 15%) × $75

= 85% × $75

= 0.85 × $75

= $63.75

Therefore, the amount she saved will then be:

= $75 - $63.75

= $11.25

She saved $11.25

Step-by-step explanation:

Write what you know

A square has 4 sides

the perimeter is the sum of the length of all 4 sides

so 4yards / 4 sides = 1 yard per side

we also know a square has all equal sides

that means our area formula will be 1 x 1

Answer:

8 nails

Step-by-step explanation:

because 4x2=8

Answer:

Step-by-step explanation:

here opposite =20, hypotenuse=29

to find adjacent use formula

a^2+b^2=c^2

20^2+b^2=29^2

400+b^2=841

b^2=841-400

b=[tex]\sqrt{441\\}[/tex]

b=21

tan theta=opposite/adjacent

=20/21

therefore tan theta =20/21

Answer:

D. tanθ = 20/21

Step-by-step explanation:

Remember that sinθ = opposite/hypotenuse. In this case, since sinθ = 20/29, we are going to say that opposite = 20 and hypotenuse = 29.

To solve for the adjacent side, use the Pythagorean theorem, a^2 + b^2 = c^2.

When you plug in your values and solve for the other leg, you'll get 21.

Now that we know that the adjacent side/other leg is equal to 21, we can find tanθ, since it's equal to opposite/adjacent.

Opposite = 20

Adjacent = 21

tanθ = 20/21

Answer:

B

Step-by-step explanation:

To find the slope of the line, we do y2-y1/x2-x1. In this case, for line n, I used the points (0,0) and (1,2). This means the slope will be 2-0/1-0. Simplify this to get 2/1 or 2. Therefore the slope for line n is 2.

To find the slope of the line, we do y2-y1/x2-x1. In this case, for line m, I used the points (0,7) and (1,8). This means the slope will be 8-7/1-0. This will make the slope 1/1 or 1. Therefore, the slope for m is 1.

Therefore, the slope for line n is greater than the slope of line m.

Answer:

25.55

Step-by-step explanation:

Let us take the number he thinked of be x .

On doubling it :-

→ N = 2x

On adding 19 :-

→ N = 2x + 19

According to Question :-

→ 2x + 19 = 70.1

→ 2x = 70.1 - 19

→ 2x = 51.1

→ x = 51.1/2

→ x = 25.55

Answer:

Finding volume:

2^2 = 4

4 x 3.14 = 12.56

12.56  x 8(height) = 100.48

100.48 divided by 3 ( x 1/3 ) =  around 33.49 in3 is your answer.

If the options dont give you 33.49 just go by 33.51 cubic meters.

You can create an equation since both have the same value of perimeter.
