What is the answer to this question?​

Answer:

[tex] \frac{1}{2} \times 10 \times 8 \\ \\ = 40[/tex]

this is the explanation.

Answer:

Step-by-step explanation:

x + 28 + 39 = 180

x + 67 = 180

x = 113

y + 113= 180

y = 67

z + 67 + 64 = 180

z + 131 = 180

z = 49

Answer and explanation

as z= 7

3z -3

3(7) -3 =21-3 =18

Answer:

Step-by-step explanation:

Probability = favorable outcome / total number of outcomes

5 numbers left and 3 of them are even.

So combined probability is:

Answer:

2.36 * 10^13 miles

Step-by-step explanation:

Given that :

Proxima centauri is at a distance of 4.24 light years away from the sun.

Distance in miles of Proxima centauri from the sun ;

1 light year = 5.9 * 10^12 miles

Number of light years from the sun * 5.9 * 10^12

= 4 * (5.9 * 10^12)

= 23.6 * 10^12 miles

= 2.36 * 10^13 miles

Step-by-step explanation:

All they do is swap the order of what is in the parentheses which means the result will stay the same, on all the other ones they changed which numbers were in the parentheses which means the result would of been different!

Answer:

£800

Step-by-step explanation:

Use the percentage formula: NV = m x OV

NV is New Value;

m is Multiplier;

and OV is Old Value.

£640 in the New value, so now we have to convert 20% to a multiplier and find out the Old value.

Make OV the subject of the formula: OV = NV / m

So 20% decrease would mean: 100 - 20 = 80 * 100 = 0.80

Divide 640 (NV) by 0.80 (m) and it will give you:

£800

And it would make sense that the OV is higher, and it matches the statement -> as the NV is the decrease.

The solution is, b. x² = 12(y + 3) equation represents a parabola that has a focus of (0, 0) and a directrix of y = −6

The parabola is a plane curve which is mirror symmetrical and is approximately U-shaped. It fits several superficial different mathematical descriptions.

here, we have,

If the focus is (0,0) and the  directrix  is y=-6, the equation will be found as follows:

Let (x,y) be any point on the parabola. Find the distance between (x,y) and the directrix, then find the distance between (x,y) and the focus. Equate these two distance equations and the simplified equation in x and y is equation of the parabola.

The distance between (x,y) and (0,0) is √(x²+y²)

The distance between (x,y) and the directrix, y=-6 is ly+6l

Equate the two distance expressions and square on both sides

√(x²+y²)=ly+6l

x²+y²=(y+6)²

simplifying and bringing terms together we get:

x²-12y-36=0

make x² the subject:

x²=12y+36

x²=12(y+3)

Hence, Answer :b. x² = 12(y + 3)

Answer:

3.35 inches

Step-by-step explanation:

Actual height of statue = 67 feets

Scale used : 1 inch = 20 feets

Let Length of drawing = x

1 inch = 20 feets

x inch = 67 feets

Cross multiply to obtain the length of the drawing in inches

20 * x = 67 * 1

20x = 67

x = 67 / 20

x = 3.35 inches

Hence, length of her drawing is 3. 35 inches
