stira [4]

Answer:

<em>The current balance in the McQuire's account is $-605.11</em>

Step-by-step explanation:

Mr. McQuire deposited his paycheck for a total account balance of $712.34 on Friday.

The next morning, his wife wrote a check for $1,267.45

As, the total account balance is less than the amount of check, so the bank will charge a $50 overdraft fee.

That means, the total amount that will be deducted from his account =(\$1267.45+\$50)= \$1317.45

So, the current balance in the McQuire's account =(\$712.34-\$1317.45)= \$-605.11

Please help with this question ​
Basile [38]

Step-by-step explanation:

m< AOC = 90°

m< AOB +m<BOC = 90°

6x-12+3x +30 = 90°

9x +18° = 90°

9x = 90- 18° = 72°

x = 8°

m<AOB =6(8)-12 = 48-12 = 36°

A recipe for fluffy slime calls for 3 3/4 cups of shaving cream, 1/2 cup of glue, 1/2 teaspoon of baking soda and 1 1/2 tablespo
DIA [1.3K]

Answer:

75/4 cups (or 18-3/4 cups)

Step-by-step explanation:

Ignore all the wording about glue, baking soda and saline.

What this question reduces to is that the recipe for :

2 people ---> requires 3 3/4 cups (or 15/4 cups) of shaving cream

10 people ----> requires 5 times the amount of shaving cream needed for 2 people

Hence shaving cream needed for 10 people

= 5 x 3 3/4 cups

= 5 x 15/4 cups

= 75/4 cups (or 18-3/4 cups)
