Find the area of the triangle where C = 18.5°, a = 32.4 cm, b = 49.2 cm
HEHE HELP

Answers

Answer:

questions mistake look questions and apply the formula 1/2 B×H

if you have a triangle and don't know where are the base and the high use this formula

area = 0.5 × side  × side  × sin the angle between the 2 sides

area = o.5 (32.4) (49.2) (sin 18.5)

         = 797.04 × sin 18.5

          =252.9

Pippa owns a snack bar.
She uses
of a kilogram of spread each day.
Spread costs £3.20 for a 1 kilogram tub and £6.15 for a 2 kilogram tub.
Pippa buys enough spread to last for 14 days.
What is the lowest price Pippa can buy this spread for?

Answers

Answer:

£43.05 (I believe, refer to step-by-step explanation.)

Step-by-step explanation:

Let's compare both of these tubs if we were to buy either of them for 14 days.

Starting with the 1 kilogram tub we need to do the calculation:

£3.20 × 14 = £44.80

(Type 3.2×14 into your calculator or write on paper this way to calculate.)

Now let's do the 2 kilogram tub.

£6.15 × 7 = £43.05

(Type 6.15×7 into your calculator or write on paper this way to calculate.)

The reason why I have put 7 instead of 14 is because it is 2 kilograms. Since Pippa uses 1 kilogram per day, you only need to buy 7. 2 × 7 = 14

So comparing either of these prices, buying 7 2-kilogram tubs is much cheaper compared to the 14 1-kilogram tubs.

BD=24

Step-by-step explanation:

I assigned my unkown sides of the triangles as x and y, where x = BD and y =AD.

I used pythagoras' theorem to find expressions for the the sides of the triangles in terms of x and y.

Both expressions had the term x^2 in them, so I equated expressions of x^2

From there i rearranged to find y.

Using my value of y, I found x.

Daniel receives a 35% employee discount on all purchases he makes at the store. If he buys his brother a jersey that is regularly priced at $24.95, what price (before tax) will Daniel pay for the jersey?

ANSWER CORRECTLY AND I WILL GIVE YOU BRAINLIEST AND GET 10 POINTS

Answers

Answer:

The price to pay is $16.22

Step-by-step explanation:

From the question, the regular price is $24.95

now, there is a discount

So the price to pay is the regular minus the discount

Mathematically, we have this as:

24.95 - 35% of 24.95

= 24.95 - 0.35(24.95)

= $16.2175

This is approximately $16.22

A. (x + 12)2 = –60
B. (x + 12)2 = 84
C. (x + 12)2 = 204
D. (x + 6)2 = –24

Answers

The Answer is

A.(x+12)2 = -60

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The formula for (a + b)² = a² + 2ab + b²

The equation x² + 24x + 60 = 0 in the form (x + p)² = q is

(x + 12)² = 84

Option A is the correct answer.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

x² + 24x + 60 = 0

We can write this as,

x² + 2 x 12 x (x) + 60 = 0

The formula for (a + b)² = a² + 2ab + b²

Add 144 on both sides.

x² + 2 x 12 x (x) + 60  + 144 = 0 + 144

x² + 2 x 12 x (x) + 144 + 60 = 144

[ 12² = 144 ]

Subtract 60 on both sides.

x² + 2 x 12 x (x) + 144 = 144 - 60

x² + 2 x 12 x (x) + 12² = 84

(x + 12)² = 84

Thus,

The equation x² + 24x + 60 = 0 in the form (x + p)² = q is

(x + 12)² = 84

Option A is the correct answer.
