Answer:
62
Step-by-step explanation:
using the order of PEMDAS, you solve 8*9 and 2*5 first, then subtract them. so it will become 72 - 10, which is 62
hope this helps!
The correct answer is D: $94,165.
First, let's find the amount of the down payment. It is 30% of the total.
310,000 x 0.30 = 93,000
Now, we just need to add on all the additional costs.
93000 + 100 + 250 +190 + 275 +70 + 280 = 94165
Answer:
C) 3x+20 < 50
Step-by-step explanation:
Since 50 is the limit as to what Mary wants to spend, the number on the left side should never be over 50, meaning that the total will be 'less' than 50
The 20 comes from how much she wants, meaning that 3x would be less than 10 dollars a gift.
Answer:
The ladder is 5.20 feet tall on the side of the building
Step-by-step explanation:
Here, we simply want to calculate the height the ladder is from the base of the building
To get this, we need a pictorial representation of what we have here.
From what we have here, we have a right-angled triangle with a hypotenuse of 10 foot and a base of 3 feet
We apply Pythagoras’ theorem to get how far is the tip of the ladder from the base of building
Pythagoras’ stated that the square of the hypotenuse equals the sum of the squares of the two other sides
In this case, let the height be x
So;
x^2 + 3^2 = 6^2
x^2 = 6^2 - 3^2
x^2 = 36 - 9
x^2 = 27
x = √27
x = 5.196 feet
which to two decimal places is 5.20 feet
