Answer:
30 Students
Step-by-step explanation:
As given
Bill is in a class of 15 boys and 35 girls.
Total number of students in the class = Number of boys + Number of girls
= 15 + 35
= 50
As given
40% of the students in the class take the bus to school.
40% is written in the decimal form.
= 0.40
Number of students take bus to school = 0.40 × Total students in class.
= 0.40 × 50
= 20
.Thus
Students not take bus to school = Total students - Number of students take bus to school
= 50 - 20
= 30
Therefore 30 students not take bus to school .
Answer:
15 students
Step-by-step explanation:
First of we have to calculate how many students there are in the class. There are 15 boys and 10 girls, whish means there are 25 people in total (15+10=25).
Since 40% takes the bus to school, 60% of the sudents do not take the bus to school. The easiest way to calculate how many students is 60% is to first divide the students with 10. 25/10 is 2.5. 2.5 students is 10% of 25 students (100% divided by 10 is 10%).
To get 60%, the number of students has to be multiplied with 6, because 10% times 6 is 60%.
2.5 (10%) times 6 is 15, so the answer is 15.
If surface area of the entire tent is 104 square feet then the depth of the tent is approximately 4.44 feet.
a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The tent can be divided into three rectangular faces and two triangular faces. Let the depth of the tent be denoted by "d".
The area of each triangularface is (1/2) base x height = (1/2) x 6 x 4 = 12 square feet.
The area of each rectangular face is length x width = d x 6 feet.
Therefore, the total surfacearea of the tent is:
2 x 12 square feet (for the triangular faces) + 3 x (d x 6 feet) square feet (for the rectangular faces) = 24 + 18d
We know that the total surface area of the tent is 104 square feet, so:
24 + 18d = 104
Subtract 24 from both sides.
18d = 80
Divide both sides by 18.
d = 80/18 ≈ 4.44 feet
Therefore, if surface area of the entire tent is 104 square feet then the depth of the tent is approximately 4.44 feet.

Answer:
Step-by-step explanation:
Accordingtotheproblem,
45° + x = 180° [Linearpair]
=> x = 180° - 45°
=> x = 135° (Ans)
Answer:
The value of x is 135°.
Step-by-step explanation:
This figure displays a straight angle, meaning that its measure is 180°.
180° - 45° = 135°
Since angle x is indeed an obtuse angle, the answer is correct! Hope this helps; have a great day.
Answer:
x=-12 x =2
Step-by-step explanation:
-x^2-10x+24=0
Divide by -1
x^2 +10x -24 = 0
Factor
What 2 terms multiply to -24 and add to 10
12 * -2 = -24
12 -2 = 10
(x+12) ( x-2) = 0
Using the zero product property
x+12 =0 x-2 =0
x=-12 x =2
