Answer:
Option 2 and 4
Step-by-step explanation:
Area of the big rectangle to fit small ones:
Area of small rectangles:
- A= 11*7=77
- B=2*11=22
- C=6*6=36
- D=6*5=30
- E=13*4=52
Now, the answer options:
- 3E+2B= 3*52+2*22= 200 > 165 ⇒ no
- A+B+C+D= 77+22+36+30= 165 ⇒ yes
- 2C+2D+2B= 2(36+30+22)=176 > 165 ⇒ no
- A+4B= 77+4*22= 165 ⇒ yes
- E+C+D+3B= 52+36+30+22= 140 < 165 ⇒ no
Answer:
n=63
Step-by-step explanation:
10(21) + .05n = 5.25
2.1 + .05n = 5.25
.05n = 3.15
n = 63

Step-by-step explanation:
1 is not. 2 is. 3 is not. 4 is. 5 is. 6 is. 7 is not. 8 is.
The general formula for a line is y=mx+c, where m is the gradient (slope) and c is the intercept.
We can extrapolate c from the graph directly - it intercepts the y axis at -1, so c has a value of -1.
The gradient can be calculated by determining what the y value changes by for each value of x. Since this evidently has a fraction gradient, it's easier to take whole numbers.
We can see a triangle with whole numbers - from (-3,0) to (0,-1). The difference in x is +3 and the difference in y is -1. Dividing these gives us -1/3.
Therefore, the gradient of the graph (i.e. m) is
-1/3Putting these together:
