Stan worked 2h days this week

Step-by-step explanation:

The given is:

Stan drives 30 minutes a day commuting to and from work
He drove h hours this week

We need to find how many days he worked

∵ Stan drives 30 minutes a day

∵ 1 hour = 60 minute

∴ 30 minutes = $\frac{30}{30}=\frac{1}{2}$ hour

∴ Stan drives $\frac{1}{2}$ hour a day

∵ He drove h hours this week

- To find the number of days that he worked divide the total

hours he drove in this week by the hour he drives in a day

∴ The number of days = h ÷ $\frac{1}{2}$

- Change the division sign to multiplication sign and reciprocal the

fraction after the division sign

∵ The reciprocal of $\frac{1}{2}$ = $\frac{2}{1}$ = 2

∴ The number of days = h × 2

∴ The number of days = 2h

Stan worked 2h days this week

Anna007 [38]

Answer:

Part A: Angle R is not a right angle.

Part B; Angle GRT' is a right angle.

Step-by-step explanation:

Part A:

From the given figure it is noticed that the vertices of the triangle are G(-6,5), R(-3,1) and T(2,6).

Slope formula

$m=\frac{y_2-y_1}{x_2-x_1}$

The product of slopes of two perpendicular lines is -1.

Slope of GR is

$\text{Slope of GR}=\frac{1-5}{-3-(-6)}=\frac{-4}{3}$

Slope of RT is

$\text{Slope of RT}=\frac{6-1}{2-(-3)}=\frac{5}{5}=1$

Product of slopes of GR and RT is

$\frac{-4}{3}\times 1=\frac{-4}{3}\neq -1$

Therefore lines GR and RT are not perpendicular to each other and angle R is not a right angle.

Part B:

If vertex T translated by rule

$(x,y)\rightarrow(x-1,y-2)$

Then the coordinates of T' are

$(2,6)\rightarrow(2-1,6-2)$

$(2,6)\rightarrow(1,4)$

Slope of RT' is

$\text{Slope of RT'}=\frac{4-1}{1-(-3)}=\frac{3}{4}$

Product of slopes of GR and RT' is

$\frac{-4}{3}\times \frac{3}{4}=-1$

Since the product of slopes is -1, therefore the lines GR and RT' are perpendicular to each other and angle GRT' is a right angle.

Two friends bring hamburger meat to your cookout. One brings 2.7 pounds, and the other brings 3.54 pounds. How much hamburger me

inessss [21]

Answer:
They bought 6.24 pounds of hamburger meat

Explanation:
We are given that:
The first friend brought 2.7 pounds of hamburger meat
The second friend brought 3.54 pounds of hamburger meat

The total amount of hamburger meat they both brought would be simply the summation of what they brought individually.

This means that:
Total amount brought = 2.7 + 3.54
Total amount brought = 6.24 pounds of hamburger meat

Hope this helps :)
