Answer:
Yes
Step-by-step explanation:
18^2+24^2=900
Square root of 900 is 30
This is derived from Pythagorean Theorem
Answer:
It is a right triangle
Step-by-step explanation:
Right Triangle
A right triangle has one of its internal angles of 90°. If such triangles, Pythagora's theorem must stand.
Being a and b the shortest sides of the triangle and c the longest side (hypotenuse), then:
[tex]a^2+b^2=c^2[/tex]
The shortest sides of the given triangle are 18 and 24, and the longest side is 30, thus the following condition must be met to prove it's a right triangle:
[tex]18^2+24^2=30^2[/tex]
[tex]324+576=900[/tex]
[tex]900=900[/tex]
Since the condition is met, we can conclude it is a right triangle

Evaluate -2x if x = 10
Answer:
-20
Step-by-step explanation:
Since x = 10, you would multiply -2 by 10
-2 is negative.
Therefore your answer is negative.
-20
Answer
-2x if x = 10 then the answer would be 20
Step-by-step explanation:
the answer is 20 because -2*10=20 and you have more positives than you do negatives so it would be positive 20
A binder at the store costs $4.87. A pack of pens at the same store costs $2.94. You pay for both the binder and pack of pens with a $20 bill
How much change do you receive?
Answer:
How much change you receive is $12.19
Step-by-step explanation:
$20 - $4.87 (price of a binder) - $2.94 (price of pack of pens) = ?
$4.87 + $2.94 = $7.81
$20 - $7.81 = $12.19

========================================================
There are two methods to get the answer.
The slightly longer method is to take 7% of the original price to get
7% of 1350 = (7/100)*1350 = 0.07*1350 = 94.50
The sales tax is $94.50
Add this onto the original price to get 1,350+94.50 = 1,444.50
----------------------------
A shortcut is to multiply the original price by 1.07
The multiplier 1.07 represents a 7% increase since
1 = 100%0.07 = 7%1.07 = 1 + 0.7 = 100% + 7%So we will have 1.07*1350 = 1,444.50
Answer:
$172.5
Step-by-step explanation:
Store A is defintley better because 6% of sales tax is $72 and $1200 + $71 = $1272 while store B: 7% of $1350 is $94.5 and $1350 + $94.5 = $1444.5. To find out how much you would save by using store A, you would simply subtract it = $1444.50 - $1272 = $172.5

A driver’s distance varies directly as the amount of time traveled. After 6 hours, a driver had traveled 390 miles. How far had the driver traveled after 4 hours?
Answer:
260 miles
Step-by-step explanation:
Answer:
260
Step-by-step explanation:
you would divide 390 by 6 to see how many hours were per hour, which is 65. You would then multiply it by 4 to see how far they drove in 4 hours, and you get 260. To prove this is right for sure you could multiply 65x2 which is 130 and add 130+260 which would make up the 6 hours and you’d get 390

Twenty-two percent of the seventh-grade class at Santa Ana Middle School has blue eyes. If the seventh-grade class has 139 students, about how many have blue eyes?
Answer:
30.58
Step-by-step explanation:
If you turn the 20% into a decimal you get .25 and do the equation .25x 139. This gives you 30.58
If the seventh-grade class has 139 students then 31 students have 31 students.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that Twenty-two percent of the seventh-grade class at Santa Ana Middle School has blue eyes
The number of students in seventh-grade class are 139.
We have to find the number of students who has blue eyes in Santa Ana Middle School.
Convert 22% to decimal value.
22/100=0.22
Now multiply 0.22 with 139
0.22×139
30.58=31 students
Hence, If the seventh-grade class has 139 students then 31 students have 31 students.
