Josie had some money in her bank account. She went shopping and spent $493.98. After shopping she still had %185. How much money

solong [7]

Answer:

$678.98

Step-by-step explanation:

Let the amount she had before she started spending be T. If she went shopping and spent $493.98 then the amount she would have is

= T - 493.98

Given that she has $185 left then

T - 493.98 = 185

Add 493.98 to both sides

T - 493.98 + 493.98 = 185 + 493.98

T = $678.98

She must have had $678.98 in her bank account to begin?

Maria wraps the gift she is taking to a friend’s birthday party. She doesn’t have much paper, so she does not overlap any of the

Elina [12.6K]

Answer:

Total paper required to wrap the gift without any overlaps: $2700\ cm^{2}$

Step-by-step explanation:

Here, we need to find the total paper required without any sides overlapping to wrap the gift.

The gift is of <em>cuboid </em>type.

Given the following:

<em>Length </em>= 15 cm

<em>Width </em>= 30 cm

<em>Height </em>= 20 cm

Please refer to the attached figure.

We can infer that to find the paper required, we actually need to the find the<em> total surface area of the cuboid</em>.

Because the gift wrap will be done <em>on the faces of gift</em> (which is of cuboid shape).

Formula for Surface Area of <em>Cuboid:</em>

$\text {Area = } 2 \times (\text{Length}\times \text{Width} + \text{Width}\times \text{Height} + \text{Length}\times \text{Height} )\\\\\Rightarrow 2 \times (15 \times 30 + 30 \times 20 + 15 \times 20)\\\Rightarrow 2 \times (450 + 600 + 300)\\\Rightarrow 2 \times (1350)\\\Rightarrow 2700 cm^{2}$

Hence, total paper required to wrap the gift without any overlaps: $2700 cm^{2}$

Pls help!I have trouble with this but ik everything is supposed to add up to 360 degrees

Ratling [72]

Because each of these angles are 90 degrees, we know they're each equal to each other.

Let's find the value of the variable y first.

We can use 5y - 17 = 2y + 50 to find the value of y.

5y - 17 = 2y + 50

-2y from both sides

3y - 17 = 50

+17 to both sides

3y = 67

Divide both sides by 3

y = 22.33

Now we need to find the value of x.

x + 44 = 7x - 248

-x from both sides

44 = 6x - 248

+248 to both sides

292 = 6x

Divide both sides by 6

x = 48.67

And there's your variables.

y = 22.33

x = 48.67
