If I can do a job in 1 and a half hours, and my friend can do the same job in 2 hours, how long will it take us working together?

Thank You for your efforts

the first one is only one solution but the second one is only one thx

Answer: a) The size of angle x is [tex]80^{\circ}[/tex].

b)  A. Corresponding angles.

Step-by-step explanation:

Since AD is parallel to EH and CG is a transversal intersecting them at B and F, then [tex]\angle ABF = \angle EFG[/tex]  ...(i)

[Pair of corresponding angles are equal lie on the same side of the transversal]

Here, [tex]\angle EFG =80^{\circ}[/tex] , [tex]\angle ABF = x[/tex]

then, [tex]x =80^{\circ}[/tex]  [Substitute values in (i)]

Hence, the size of angle x is [tex]80^{\circ}[/tex].

Reason for this: Corresponding angles.

x=0 or x=32

Step-by-step explanation:

x equals 0 or 32

Answer:

13 / 8

Step-by-step explanation:

Given that :

Length of board = 13 feets

Number of equal board section needed = 8

The largest possible length of 1 section of the board :

Since each section are the same :

Length of board / number of board sections

= 13 / 8

Answer:

x= -1.7

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

x = -1.7.

Step-by-step explanation:

3.7 = 5x + 12.2

Subtract 3.7 from both sides:

0 = 5x + 12.2 - 3.7

0 = 5x + 8.5

Subtract 5x from both sides:

-5x = 8.5

x = 8.5 / -5

x = -1.7.

Answer:

The amount of candy you had before is 8.

Step-by-step explanation:

75% + 25% makes 100% percent.

If we take 25% off from 8, you get 6.

A quick way to do this is: 8(.25)

If you solve that, you get 2. 8 - 2 is 6, which is what you originally had.

Answer: 7 - 2n

Step-by-step explanation:

a1 = 5

a6 = -5 = a + (n - 1)d = a + (6 - 1)d

a + 5d = -5

Since a1 = 5

5 + 5d = -5

5d = -5 - 5

5d = -10

d = -10/5

d = -2

Therefore, the equation to calculate the nth term of this sequence will be:

= a + (n-1)d

= a + (n - 1)-2

= 5 -2n +2

= 7 - 2n

Answer:

=13

Step-by-step explanation:

square root of 21 is about 6

6 + 7 / 6 - 7

=  13 / -1

=13

Answer:

50.24 yards=Circumference

Step-by-step explanation:

So first the formula to find circumfence is π*diameter

The diamtere is 16

π is told to be counted as 3.14

3.14*16=50.24

So the Circumfrnce is 50.24

Answer:

hope it helps

Step-by-step explanation:

1) -72

2) -50

3) 0.2

Answer:

1. 24÷ (-6)=− 4

Factor the numerator and denominator and cancel the common factors.

2. -15 ÷ 0.3=−  50

3. -4 ÷ (-20)=

Reduce the expression, if possible, by cancelling the common factors.

Exact Form:

1/5  

Decimal Form:

here you go! :) hope I am right

Here is the easy way to memorise the truth value of p ^ q.

p ^ q will be true only if p and q both are true. Otherwise, false.

Given p = x is prime and q = x is even. If we replace x by 2 then we would get

p = 2 is prime

q = 2 is even

The statement for p and q both are true because 2 only has two factors which are only 1 and 2 itself. 2 is also considered an even number (2,4,6,8,...)

Since p = true and q = true then p and q = p^q = true and true = T/True

The second choice. p^q is True

Answer:

  correct as marked (145°)

Step-by-step explanation:

Angles ABC and DBE are "vertical" angles. As such, they are congruent.

  ∠ABC = ∠DBE = 145°

Answer:

there is the answer 347.82

The answer to this question is 347.82

Answer:

Option (3)

Step-by-step explanation:

From the figure attached,

[tex]\frac{BC}{FD}=\frac{AC}{ED}[/tex]

[tex]\frac{3}{1}= \frac{3.9}{1.3}[/tex]

[tex]\frac{3}{1}= \frac{3}{1}[/tex]

Therefore, these corresponding sides are proportional (In the same ratio).

Angle between these sides are also equal. (Given in the picture)

Since, SAS rule of similarity states that, two triangles will be similar if their corresponding two sides are proportional and angle between these two sides are equal.

Option (3) will be the answer.

Answer:

y = 2x - 3

Step-by-step explanation:

Slope intercept form : y = mx + b

6x - 3y = 9

     -3y = -6x + 9

      [tex]\frac{-3}{-3}y=\frac{-6}{-3}x+\frac{9}{-3}\\\\[/tex]

          y = 2x - 3

Answer:

hmm it should be -4, 6

Step-by-step explanation:

first you go down and it goes down to -4

next it went to the right which is 6 and anything to the right is generally more or so positive.

Answer:

$300.64

Step-by-step explanation:

Step one:

Given data

Jennifer had $256.86

She made a deposit of $43.78

Required

The total amount in the account

Step two:

To get the balance, we need to sum the previous amount with the deposited amount

Total= 256.86 +43.78

Total=$300.64

The balance is $300.64

Answer:
