Answer:
10
Step-by-step explanation:
(4 * 5) / 2 = 20 / 2 = 10
Answer:
Triangle R and triangle S are congruent triangles, so finding the area of triangle S would give us the area of triangle R.
The area of a triangle can be calculated as 1/2(bh), where b is the base and h is the height.
In this case, we have: 1/2(5)(4). This simplifies to 10.
So, the area of triangle R is 10 square meters.

0=1-2y+14x what is the slope and the y-intercept
Answer:
slope: 7
y-intercept: 1/2
Step-by-step explanation:
Put it into the form y = mx + b where m is the slope and b will be the y-intercept. (For example, in the equation y = 3x + 2 the slope is 3 and the y-intercept is 2).
[tex]0=1-2y+14x\\2y=1+14x\\2y = 14x+ 1\\y = 7x + 1/2[/tex]
So you know that m = 7, so the slope is 7
and
b = 1/2, so the y-intercept is 1/2.

DEF, find the length of d, to the nearest tenth, given that ∠D=110o, e = 10cm and f = 14cm.
Answer:
d = 19.8 cm
Step-by-step explanation:
Use the law of cosines
[tex]d^{2} = e^{2} + f^{2} -2ef cos D\\d^{2} = 10^{2} + 14^{2} -2(10)(14) cos 110\\[/tex]
= 100 + 196 - 280 cos 110
= 296 - (-95.765640)
= 391.765640
[tex]d = \sqrt{391.7656401}[/tex]
d = 19.8 cm
Help plsssssssssssssssssssssss
Explanation:
5.
The initial cost is $65.42
25% of 65.42 is 16.355
Add 16.355 + 65.42 and the total cost is: $81.78
6.
The initial cost is $12.50
3.2% of 12.50 is 0.4
Add 0.4 + 12.50 and the total cost is: $12.90
A rectangle has length (x + 5)cm and width (x –2)cm. Its area is 60 cm 2
Area = length x width
60 = (x+5) (x-2)
60 = x^2 + 3x -10
Subtract 60 from both sides:
x^2 +3x -70 = 0
Solve for x by finding 2 numbers when added together = 3 and when multiplied by each other = -70
x = -10 and 7
Since the sides have to be a positive number we need to use 7
The length = x+5 = 7+5 = 12 cm
The width = x-2 = 7-2 = 5 cm

Eighty percent of a roof, or 2800 square feet of the roof, has been re-shingled.
What is the total area of the roof?
A 35,000 sq ft
B 22.400 sq ft
C 3500 sq ft
D 2240 sq ft
Answer:
a) 35,000 sq ft
Step-by-step explanation:
x = total area
the question is: 80% of what number equals 2800
.8x = 2800
x = 2800/0.8
x = 3500

Write a System of Equations to solve the following problem:
The county fair is a popular field trip destination. This year the senior class at High School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 13 vans and 2 buses with 211 students. High School B rented and filled 4 vans
and 4 buses with 268 students. Each van and each bus carried the same number of students. Find the number of students in each van and in each bus.
#students each VAN can carry:
#students each BUS can carry:
Answer:
each van carries 7 students
each bus carries 60 students
Step-by-step explanation:
let v = # students in a van
let b = # students in a bus
system of equations:
13v + 2b = 211
4v + 4b = 268
I multiplied the 1st equation by -2 to eliminate the 'b' terms
-26v - 4b = -422
+ 4v + 4b = 268
-22v = -154
v = 7
substitute '7' for 'v':
4(7) + 4b = 268
28 + 4b = 268
4b = 240
b = 60
Answer:
13v + 2b = 211
4v + 4b = 268
#students each VAN can carry: 7
#students each BUS can carry: 60
Step-by-step explanation:
Let v = number of students in each van.
Let b = number of students in each bus.
High School A:
13v + 2b = 211
High School B:
4v + 4b = 268
The system of equations is
13v + 2b = 211
4v + 4b = 268
We will solve this system of equation with the addition method.
Write the first equation as it is. Divide both sides of the first equation by 2 and write it below the first equation. Then add the equations.
13v + 2b = 211
(+) -2v - 2b = -134
----------------------------
11v = 77
Divide both sides by 11.
v = 7
Substitute 7 for v in the first original equation and solve for b.
13v + 2b = 211
13(7) + 2b = 211
91 + 2b = 211
Subtract 91 from both sides.
2b = 120
Divide both sides by 2.
b = 60
Answer:
13v + 2b = 211
4v + 4b = 268
#students each VAN can carry: 7
#students each BUS can carry: 60
