=(49+11)/5

=60/5

=12

Answer:

Answer is 65

Step-by-step explanation:

Take 7 to the power of two and do 7x7 and whatever answer you get add it to 11 so do 49+11 and then whatever answer you get add it to 5, so 60+5

Hope that helps

Answer:

The scale factor SF = [tex]\frac{7}{3}[/tex] ⇒ C

Step-by-step explanation:

If the point (x, y) dilated by a scale factor n, then the coordinates of its image are (n x, n y)

Let us solve the question

∵ The coordinates of the point K are (-3, 6)

∴ x = -3 and y = 6

∵ The coordinates of its image k' are (-7, 14)

→ From the rule above the image is (n x, n y)

∵ The scale factor is n

∴ n x = -7

∴ n y = 14

→ Substitute x by -3

∵ n (-3) = -7

∴ -3n = -7

→ Divide both sides by -3

∵ [tex]\frac{-3n}{-3}[/tex] = [tex]\frac{-7}{-3}[/tex]

∴ n = [tex]\frac{7}{3}[/tex]

→ Substitute y by 6

∵ n (6) = 14

∴ 6n = 14

→ Divide both sides by 6

∵ [tex]\frac{6n}{6}[/tex] = [tex]\frac{14}{6}[/tex]

∴ n = [tex]\frac{7}{3}[/tex]

→ Both coordinates gave the same value of n

∴ The scale factor SF = [tex]\frac{7}{3}[/tex]

Answer:

288

Step-by-step explanation:

Since, the product of the HCF and LCM of two numbers is equal to the product of the two numbers.

Therefore,

The product of the two numbers

[tex] = HCF \times LCM \\ \\ = 12 \times 24 \\ \\ = 288[/tex]

Answer:

22

Step-by-step explanation:

So the number of valentines made is going to equal the number of kids * the number of kids, so all you have to do is the square root of 484.

This is 22, because 22 * 22 = 484.

Answer:

22

Step-by-step explanation:

Answer:

50 cm

Step-by-step explanation:

So the first step is to find the height, and to do that you know that the area of a triangle is height * base / 2 =  area. Plugging in the numbers you have, you get:

[tex]height*48/2=336[/tex]

Then, this becomes

[tex]height * 24 = 336[/tex]

Divide both sides by 24

[tex]height = 14[/tex]

Now you can use the base and the height to find the hypotenuse using the Pythagorean Theorem: [tex]a^{2} +b^{2} =c^{2}[/tex]

[tex]48^{2} +14^{2} =c^{2} \\2304 + 196 = c^{2}\\2500 = c^2\\50 = c\\c = 50[/tex]

Therefore the length of the hypotenuse is 50 cm

Answer:

y=-2x+7

Step-by-step explanation:

slope intercept form: y=mx+b

Slope formula: [tex]\frac{rise}{run}[/tex] or [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{2}}[/tex]

You can pick any two equations. In this example, I chose the firsts 2.

(0,-7) and (1,-9)

Plug into the slope formula,

-9+7 over 1-0 which is -2/1 or -2

The m in y=mx+b is the slope, the equation above is the sloe formula meaning -2 is the slope. The b is the y, when it is at 0. The y at 0 for this equation is -7. Thus, when plugging in the equation, y=-2x-7

Answer:

See explanation.

Step-by-step explanation:

The question requires you to determine the volume of both the box and the disc case then find how many of the disc cases can fit in to the box.

The volume of the box

V= l*w*h

V= 29 * 15 * 20 = 8700 cm³

The volume of the disc case

V=l*w*h

V=1.4 * 14.2*19.3

V=383.684 cm³

The number of disc cases that fit in the box will be;

8700/383.684

22.67

In this calculation, it is clear that 19 of these disc cases will definitely in the box because the box can accommodate 22 of these disc cases.

Answer:

We start with the equation:

A: 3*(x + 2) = 18

And we want to construct equation B:

B: X + 2 = 18

where I suppose that X is different than x.

Because in both equations the right side is the same thing, then the left side also should be the same thing, this means that:

3*(x + 2) = X + 2

Now we can isolate the variable x.

(x + 2) = (X + 2)/3

x = (X + 2)/3 - 2

Then we need to replace x by  (X + 2)/3 - 2 in equation A, and we will get equation B.

Let's do it:

A: 3*(x + 2) = 18

Now we can replace x by =  (X + 2)/3 - 2

3*( (X + 2)/3 - 2 + 2) = 18

3*(  (X + 2)/3 ) = 18

3*(X + 2)/3 = 18

(X + 2) = 18

Which is equation B.

Answer:

this is a required answer.

Answer:

See Below.

Step-by-step explanation:

We want to verify:

[tex]\cos(x-y)-\cos(x+y)=2\sin(x)\sin(y)[/tex]

We will utilize the following identities:

[tex]\cos(x-y)=\cos(x)\cos(y)+\sin(x)\sin(y)[/tex]

And:

[tex]\cos(x+y)=\cos(x)\cos(y)-\sin(x)\sin(y)[/tex]

So, by substitution, we acquire:

[tex](\cos(x)\cos(y)+\sin(x)\sin(y))-(\cos(x)\cos(y)-\sin(x)\sin(y))=2\sin(x)\sin(y)[/tex]

Distribute:

[tex]\cos(x)\cos(y)+\sin(x)\sin(y)-\cos(x)\cos(y)+\sin(x)\sin(y)=2\sin(x)\sin(y)[/tex]

The first and third term will cancel:

[tex]\sin(x)\sin(y)+\sin(x)\sin(y)=2\sin(x)\sin(y)[/tex]

Combine like terms:

[tex]2\sin(x)\sin(y)\stackrel{\checkmark}{=}2\sin(x)\sin(y)[/tex]

Step-by-step explanation:

LxWxH=V or BxH=V

L=8

W=1

H=12

8x1x12=96

Answer: 96in²

Step-by-step explanation: To find the volume, you multiply the Length, Width, and Height.

The formula is whl, which means W × H × L.

So, we'll multiply 8 by 1 by 12.

Step 1.

Multiply 8 by 1.

8 × 1 = 8

Step 2.

Multiply 8 by 12.

8 × 12 = 96

Hence, 96in² is the answer.
