Answers

Answer:

x = 7.15

Step-by-step explanation:

Taking 33 as the reference angle,

hypotenuse = x

base = 6

Cos 33 = base/hypotenuse

Cos 33 = 6 / x

x = 6/ cos 33

x = 7.15

Lorenzo's family is driving to the beach to go kayaking with sea otters. The beach is 85 miles from Lorenzo's house. They have already driven 63 miles. Help and plz put the equation

Answers

Answer: See explanation

Step-by-step explanation:

Your question isn't complete but I'm guessing that you want to find the equation to know the miles left for Lorenzo family to reach the beach.

The equation will be gotten by subtracting the distance that the family has driven already from the total distance from their house to the beach. This will be:

= 85 miles - 63 miles

= 22 miles

Answers

Answer:

the first one is the correct one

Step-by-step explanation:

a great way to check this is to use demos .com

Answer:

its the first one

Step-by-step explanation:

our  vertex is (-2,0)

so replace it in the equation y ≤ (x + 2)^2

so, 0 ≤ (-2 + 2)^2

= 0 ≤ (-4)^2

= 0 ≤ 16

look at that statement, is 0 less than or equal to 16? Yes. Therefore it is correct, so you shade out side of the parabola.

TIP: If the parabola opens up and:

        y <, then shade outside.

        y >, then shade inside.

Do the opposite if the parabola opens down.

One leg of a right triangle is 3 cm and the hypotenuse is 5 cm. Joni found the length of the other leg by evaluating √32 + 52. What error did she make? How would you help her correct her error so she is less likely to make the same error in the future?

Answers

Answer: See explanation

Step-by-step explanation:

We should note that the hypothenuse is the longest side in a triangle. Therefore, the length of the other side will be represented by x. This is then solved below:

x² + 3² = 5²

x² + 9 = 25

x² = 25 - 9

x² = 16

x = ✓16

x = 4cm

The other leg is 4cm

Joni shouldn't have added the hypothenuse to the other leg but rather subtracted the square of the other leg from the square of the hypothenuse and then find the square root.

Solve for y. 2(3y-7)=16​

Answers

Answer:

y=5

Step-by-step explanation:

First, distribute the 2 to the 3y and -7

6y - 14 = 16

Second, add 14 to both sides.

6y = 30

Third, divide both sides by 6

y = 5

As you can see y equals 5!

I hope the explanation helped and have a great day!

Answer:

y = 5

Step-by-step explanation:

2(3y - 7) = 16

distributive property:

2(3y - 7) = 16

6y - 14 = 16

add 14 on both sides

6y - 14 + 14 = 16 + 14

6y = 30

divide both sides by 6 :

[tex]\frac{6y}{6} = \frac{30}{6}[/tex]

y = 5

to check, subtitute 5 for y

2 (3(5) - 7) = 16

2(18 - 7) = 16

30 - 14 = 16

16 = 16

Step-by-step explanation:

Mehvish buys 1/2 kg carrots, 3 kg potatoes, 2 kg onions and 1 1/2kg of chicken.

PRICE LIST
carrots: 50p per kg
potatoes: 64 per kg
onions: 42p per kg
Chicken: £6 per kg

She pays with a £20 note.

Work out the change that Mehvish should get.

Answers

Answer:

The amount of change will be £7.99

Step-by-step explanation:

Here, we want to calculate the amount of change that Mehvish should get

1/2 kg carrots at 50 p per kg will be;

1/2 * 50 = 25 p

3 kg potatoes at 64 p per kg will be

3 * 64 = p 192

2 kg onions at 42 p per kg

2 * 42 p = 84 p

1 1/2 kg chicken at £6 per kg will be:

since £1 is 100 p

1.5 * 6 = £9 (9 * 100 p = 900p)

since £1 is 100 p

£20 will be;

20 * 100 = 2,000 p

So let us make the subtraction as follows;

2,000- 900 - 84-192 - 25 = 799 p

In pounds, this is divided by 100

we have this as 799/100 = £7.99
