Find the value of x.

Answer:

Step-by-step explanation:

A i think

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:

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.

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

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:

3/4 pizza is left. If you want an explanation, ask me ;>

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:

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:

He can fill 3 crates, there would be 1 orange left over

Step-by-step explanation:

four equal rows of three oranges = 12 total. 12x3= 36, so 1 left over

Answer:

12

Step-by-step explanation:

Answer:

look at the picture i have sent

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:

i round my answer so its 4 but if it wrong its 3

Step-by-step explanation:

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.

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:

C

Step-by-step explanation:

9x + 18 = 6(x + 3) + 3x = 3(3x + 6)

3x + 15 = 3(2x + 5) - 3x = x + 2x + 15

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
