Step-by-step explanation: It's important to understand that the sum of the measures of the interior angles of a triangle is always 180 degrees.
So let's first add up the measures of the two angles we know.
So we have 30 + 4 which is 75 degrees.
The missing angle will be equal to 180 minus 75.
So the missing angle measure is 105 degrees.

Mr. Smith is draining his pool to have it cleaned. At 8:00 A.M., it had 2000 gallons of water and at 11:00 A.M. it had 500 gallons left to drain. What is the rate of change in the amount of water in the pool?
Answer:
500 gallons per hour
Step-by-step explanation:
rate =2000-500 gallons/ 3hours
=1500 gallons/3 hours
=500gallons per hor
Using mathematical operations, we know that the rate of change is 500 gallons of water per hour.
What are mathematical operations?The rules that specify the order in which we should solve an expression involving many operations are known as the order of operations. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction (from left to right). An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands.So, the rate of change:
Hours passed is 3. (11 - 8 = 3)The water decreased after 3 hours is 1500. (2000 - 500 = 1500)Now, calculate as follows:
Rate of change = 2000 - 500/3Rate of change = 1500/3Rate of change = 500 per hourTherefore, using mathematical operations, we know that the rate of change is 500 gallons of water per hour.

Trenton and Maria record how much dry food their pets eat on average each day.• Trenton’s pet: 4/5 cup of dry food• Maria’s pet: 1.25 cups of dry food. Based on these averages, how many more cups of dry food will Maria’s pet have eaten than Trenton’s pet will have eaten over 2 seven-day weeks? *
1
Answer:
9/20
Step-by-step explanation:
so since trentons pet eats 4/5 of the food each day and marias eats 1.25 each day so we cant put 4/5 and 1.25 to see wat the awnser is so we make 1.25 a fraction 1 1/4 but the demoninators arent the same so what we do is make them the same so i multiply 4x5 and get 20 that is out new denominator and 4x4 is 16 so the 4/5 is now 16/20 and the 1 1/4 is 1 5/20 then subtract but since we have a whole number we subtract that first but they dont go together but we do it anyway and get 4 left over we put the 4 into the 5/20 and get 9/20 and thers ur awnser
A 747 airplane weighs about 600,000 pounds. It can also be expressed as approximately 3 times 10 Superscript n tons. If there are 2,000 pounds in 1 ton, which is the most reasonable value of n? –2 –1 2 4
Answer:
n=2
Step-by-step explanation:
2000 pounds = 1 ton 600000 pounds = X tons Hence X tons = (600000 x 1) ÷ 2000 = 300 tons 3 x 10ⁿ = 300 Hence 3 x 10ⁿ = 3 x 10² Hence n= 2

if the area of the right angle to measure 308 square meters and solve an equation to find the value of y
Answer:
y = 14
Step-by-step explanation:
Area of rectangle = 308 m²
Length = (6y - 7) m
Width = 4 m
Area of rectangle = length × width
Plug in the values
308 = (6y - 7) × 4
308 = 6y×4 - 7×4
308 = 24y - 28
Add 28 to both sides
308 + 28 = 24y
336 = 24y
Divide both sides by 24
14 = y
y = 14

Magdalena buys a lawnmower that costs $122.50. The
sales tax in her town is 8%. Write an equation of the
form y=kx to represent the amount of tax on an item
that costs x dollars. Use the equation to find the
amount of tax on the lawnmower. SHOW YOUR WORK. i need help asap!
Answer:
Here u go :3
Step-by-step explanation:
p = price
p=122.50x
x = 8%
122.50 * 0.08 = 9.80
The amount of sales tax on the lawnmower is $9.80.
A sales tax is a form of tax that is levied on the purchase of goods and services. Taxes increase the cost of a good or service. The amount of tax paid can bee determined by multiplying the tax rate by the cost of the lawnmower.
The amount of tax paid = cost of the lawnmower x sales tax
= $122.50 x 0.08
= $9.80
