Answer:
90 and 8
Step-by-step explanation:
The question is : the sum of two numbers is 98 and their difference is 82 find the two numbers
Let two numbers are x and y.
Sum of two numbers is 98
x+y = 98 ....(1)
The difference of two numbers is 82.
x-y=82....(2)
Adding equation (1) and (2) we get :
x+y+x-y=98+82
2x=180
x=90
Put the value of x in equation (1)
90+y = 98
y = 8
Hence, the two numbers are 90 and 8.
Given:
Total number of students = 27
Students who play basketball = 7
Student who play baseball = 18
Students who play neither sports = 7
To find:
The probability the student chosen at randomly from the class plays both basketball and base ball.
Solution:
Let the following events,
A : Student plays basketball
B : Student plays baseball
U : Union set or all students.
Then according to given information,




We know that,



Now,





It means, the number of students who play both sports is 5.
The probability the student chosen at randomly from the class plays both basketball and base ball is


Therefore, the required probability is
.
Answer:
$3.49
12 quarters,4 dimes,1 nickle, 4 pennies
Step-by-step explanation:
First remember that;
Quarter=25 pennies
Dime=10 pennies
Nickel =4 pennies
I cent =0.01$
Given the amount as $3.50
Assume you use 4 quarters, this means a whole dollar, so it will be;
1 dollar = 4quarters
3 dollars=?
cross multiply
3×4=12 quarters
The remaining $0.49
Here identify 40 cents, which is 40 pennies
But 10 pennies=1 dime
so 40 pennies=?
cross-multiply
(40×1)÷10=4 dimes
and a nickel for 4 pennies.
Answer:
A sphere
Step-by-step explanation:
A cross section of a three dimensional figure is the surface or intersection of the three dimensional figure and a plane, it is the shape obtained by cutting straight through the three dimensional figure
The shape of an inclined cross section of a cube can be a triangle however, he shape of a horizontal and inclined cross section of a sphere is a circle.
