HELPPPP MEEE!!!! PLZZZZZ

Answer:

3x - 2y

= 3(2) - 2(10)

= 6 - 20

= -14

the answer is C

Answer:

[tex]x=2[/tex]

[tex]y=10[/tex]

So the multiply 3 × 2

[tex]3 * 2=6[/tex]

Then multiply 2 × 10

[tex]2 * 10=20[/tex]

Then subtract 6 - 20.

This shows that the answer will be negative.

[tex]6-20= -14[/tex]

So the answer is [tex]-14[/tex]

Hope this helps

Answer:

2 * -4 = -8

Step-by-step explanation:

2 * -4 = -8

It is just like multiplying two numbers like... 2 * 4 = 8

You must need to know that:

+a * -b = -c

-a * -b = +c

+a * +b = +c

In your question;

+a * -b = -c

a = 2

b = -4

c = -8

therefore:

2 * -4 = -8

Answer:

m∠A 60°, m∠B= 120°, m∠C =60°, m∠D=120°

Step-by-step explanation:

[tex] In\: ||^{gm} \: ABCD, \: BK\perp AD... (given) \\

\therefore \angle BKA = 90\degree \\

In\:\triangle BKA, \\\\

\cos \angle A = \frac{AK}{AB}\\\\

\cos \angle A = \frac{3}{6}\\\\

\cos \angle A = \frac{1}{2}\\\\

\cos \angle A = \cos 60\degree.. (\because \cos 60\degree = \frac{1}{2}) \\\\

\huge \red {\boxed {\therefore \angle A = 60\degree}} \\[/tex]

Since, adjacent angles of a parallelogram are Supplementary.

[tex] \therefore \angle A + \angle B = 180\degree \\

\therefore 60\degree + \angle B = 180\degree \\

\therefore \angle B = 180\degree - 60\degree\\

\huge \purple {\boxed {\therefore \angle B = 120\degree}} \\[/tex]

Since, opposite angles of a parallelogram are congruent.

[tex] \therefore \angle C = \angle A

\\

\huge \red{\boxed {\therefore \angle C = 60\degree}} \\\\

\therefore \angle D = \angle B

\\

\huge \purple {\boxed {\therefore \angle D = 120\degree}} \\[/tex]

Answer:

d=6+2t

Step-by-step explanation:

Let

t=number of ten dollar bills

d=number of dimes

Number of dimes is six more than two times the number of ten dollar bills

d=6+2*t

d=6+2t

Answer:

42°

Step-by-step explanation:

given OA and OC are perpendicular, the angle between the lines are 90°

this means that ∠AOB and ∠BOC add up to 90°, i.e.

(6x-6) + (5x+8) = 90

6x-6 + 5x+8 = 90

11x - 6 +8 = 90

11x + 2 = 90 (subtract 2 from both sides)

11x = 90- 2

11x = 88 (divide both sides by 11)

x = 8  

Hence, m∠BOC

= 6x - 6

= 6(8) - 6

= 48 - 6

= 42°

Answer:

[tex]0.50 \leq \frac{x+2}{x+10}\\[/tex]

At least 6 strikes

Step-by-step explanation:

The required numerical data is missing from the question. In the original question, Roni gets a strike 2 out of 10 times and her goal is to have a minimum strike rate of 50%. The number of consecutive strikes required is given by the following inequality:

[tex]0.50 \leq \frac{x+2}{x+10}\\[/tex]

Solving the inequality:

[tex]0.5x+5 \leq x+2\\3\leq0.5x\\x\geq6[/tex]

Roni needs at least 6 strikes.

After 6 strikes, she would have 8 out of 16, which equals exactly 50%.

Answer:

The correct option is a) 3n - 4 = 15

Step-by-step explanation:

The product of 3 and a number means 3 multiplied by a number (n)

So it'll be 3*n or simply 3n

Now, it says 4 less than the product

So 4 less than 3n

That is equal to 3n minus 4 or 3n -4

So we come to the conclusion that

3n - 4 = 15

Good luck on your assignment...

Answer:

It seems each number is 3 less than the previous number.

We must sum these 10 numbers

40, 37, 34, 31, 28, 25, 22, 19, 16, 13

The sum would equal the average of the middle 2 numbers times 10.

(28 + 25) / 2 = 53 / 2 = 26.5

We multiply by 10 because there are 10 numbers and this equals

265

Answer:

40+37+34+31+28+25+22+19+16+13=265

Answer:

(B) [tex]76\pi$ sq. in.[/tex]

Step-by-step explanation:

Since the base of the cone and one circular face of the cylinder is not visible,

The surface area of the rocket=Base Area of the Cylinder+Lateral area of the Cylinder+Lateral Area of the Cone+

[tex]R$adius =4 Inches\\Height of the cylinder =5 Inches\\Therefore:\text{Lateral area of a Cylinder+Base Area of the Cylinder}=2\pi rh+\pi r^2\\=(2\times \pi \times 4 \times 5)+(\pi \times 4^2)\\=40\pi+16\pi \\=56\pi$ sq. in.[/tex]

Lateral Area of a Cone [tex]=\pi rl[/tex]

Using Pythagoras theorem:

[tex]Hypotenuse =\sqrt{opposite^2+adjacent^2} \\=\sqrt{3^2+4^2} \\=\sqrt{25}\\ =5 in.[/tex]

Therefore: Lateral Area of a Cone [tex]=\pi \times 4\times 5 =20\pi$ sq. in.[/tex]

Therefore, Surface area of the rocket

[tex]=56\pi+20\pi\\=76\pi$ sq. in.[/tex]

Answer:

The answer is 76π sq. in.

Answer:

[tex]\frac{9}{8}[/tex]

Step-by-step explanation:

In order to find the answer to this question you will have to use KCF (Keep, Change, Flip) on the equation and then multiply.

[tex]-\frac{3}{8} \div-\frac{1}{3}[/tex]

Use KCF:

[tex]-\frac{3}{8} \times-\frac{3}{1}[/tex]

Now multiply:

Negative times a negative equals a positive.

[tex]3\times3=9[/tex]

[tex]8\times1=8[/tex]

[tex]=\frac{9}{8}[/tex]

Hope this helps.

Answer: 9/8

Explanation: It's important to understand that dividing by a fraction is the same thing as multiplying by the reciprocal of the fraction.

So our problem can be rewritten as (-3/8) · (-3/1).

Remember that a negatives times a negative is a positive.

So (-3/8) · (-3/1) is 9/8.

Remember, multiply across the top and bottom.

Answer:

It is multiplication

Step-by-step explanation:

It is multiplication because when you divide 9,460,730,472,580.8 by 299,792,458 you will get 31557.6 so that means,

9,460,730,472,580.8/299,792,458 = 31557.6

so, 299,792,458 * 31557.6 = 9,460,730,472,580.8

So the answer is Multiplication by 31557.6

Answer:

[tex]a = \frac{2(vt-d)}{t^{2} }[/tex]

Step-by-step explanation:

Given the formula for calculating the displacement of a body as shown below;

[tex]d = vt - \frac{1}{2} at^{2}[/tex]

d = displacement

v = final velocity

a = acceleration

t = time

To make the acceleration a the subject of the formula, the followin steps must be taken;

Step 1: Subtract vt from both sides of the equation

[tex]d-vt = vt-vt-\frac{1}{2}at^{2} \\ d-vt = -\frac{1}{2}at^{2}\\2(d-vt) = -at^{2}[/tex]

Step 2: Divide both sides by t²

[tex]\frac{2(d-vt)}{t^{2} } = \frac{-at^{2} }{t^{2} } \\a = \frac{-2(d-vt)}{t^{2} }[/tex]

[tex]a = \frac{2(vt-d)}{t^{2} }[/tex]
