Step-by-step explanation:

Area of trapezium

=1/2 h(a+b)

=1/2 2(6+4)

=1/2 2.10

=1/2 20

=10cm. cm

Answer:

10 cm² (the answer of blue trapezium)

Step-by-step explanation:

s=((4+6)*2)/2=10

Answer:

Step-by-step explanation:

Step one:

given data

needed amount= $80

the amount already saved= $8

earnings per hour= $9

let the number of hours worked be n

and let y represent the total

the situation represented linearly is

y=mn+c

Step two:

substituting our data to find n

9n+8>80

9n>80-8

9n>72

divide both sides by 9

n>72/9

n>8

Therefore he must work a minimum of  8houees

Answer:

-4-8=-12. 3-(-1)=3

Together they equal -9

Step-by-step explanation:

You have to multiply by the - sign outside the parentheses and the first one just count backwards

Answer:

-12 and -2

Step-by-step explanation:

Answer:

8+(t+3)

Step-by-step explanation:

the sum is when you add two numbers together. so you would add t with 3 and out it in parentheses so you make sure that happens first. then you add it to 8 since 8 is being increased by the sum.

Answer:

30

5 X 3 ÷ 8 + 3 X 2/5

= 15/11 X 2/5

(Take LCM of 5 and 11. LCM - 55)

15 X 5. 75

_____ =. ___

11 X 5. 55

2 X 11. 22

_____ =. ___

5 X 11 55

75 X 25. 1650

______ = ______

55. 55

= 30

Proof:

Multiply both of the sides by 3. You would get 12d = c - d. Add d on both sides, and you would get c = 12d

Here, we are required to proof c = 13d from 4d=1/3(c-d)

Ultimately, c = 13d (proof)

We have;

Cross product

4d × 3 = c - d

therefore, By collecting like terms;

C = 12d +d

and Ultimately, c = 13d ......

Answer:

Answer: -1

Step-by-step explanation:

The Polynomial Remainder Theorem

It states that the remainder of the division of a polynomial f(x) by (x-r) is equal to f(r).

We have the polynomial:

[tex]f(x)=x^3+x^2+x+1[/tex]

And we need to determine if x=1 and/or x=-1 are zeros of the polynomial.

Considering the polynomial remainder theorem, if we try any value for x, and the remainder is zero, then that value of x is a root or zero of the polynomial.

Find:

[tex]f(1)=1^3+1^2+1+1[/tex]

f(1)=4

Thus, x=1 is not a zero of f(x)

Now, find:

[tex]f(-1)=(-1)^3+(-1)^2+(-1)+1[/tex]

[tex]f(1)=-1+1-1+1=0[/tex]

Thus, x=-1 is a zero of f(x)

Answer:

12/13

Step-by-step explanation:

A standard deck of cards has four suites

Total number of cards = 52

Total number of cards which are 4 is = 4

The probability that the card selected is 4 = 4/52 = 1/13

S,  the probability that the selected card is not a 4 = 1 - (1/13 )= 12/13
