Hi!
50) The answer is 104 cm
Steps:
-recognize that the shape is a triangle and a rectangle put together
-find the measurements of the triangle (8&6) and the rectangle (8&10)
-find the areas of the triangle (l x h divided by 2= a) and the rectangle (l x h+a)
-add the areas together (24& 80)
51) The answer is 800ft
Steps:
-split the irregular shape into a triangle and a rectangle
-find the area of both the triangle (200) and of the rectangle (600)
-add together (200+600= 800)
52) The answer is 156 cm
Steps:
-recognize that the shape can be split into 3 rectangles
-find the measurements for all three rectangles (12&5, 12&6, 3&8)
-Use the formula l x h= a for each rectangle
-add each one of the rectangles together (60, 72, &24)

Find the domain and range of the exponential function h(x) = –343^x. Explain your findings. As x decreases, does h increase or d

Snowcat [4.5K]

Answer:

As x decreases, h increases (but never touches)

As x increases, h decreases (but never touches)

Step-by-step explanation:

If you graphed the exponential, you would be able to see that it is stuck in the 3rd quadrant.

Domain: (negative infinity, 1)

Range: (negative infinity, 0)

DUE IN 5 MINUTES PLZ HELP LOL:)

katen-ka-za [31]

1) Yes

2) 5 minutes

3) 2 minutes

Step-by-step explanation:

1: Yes because, using the vertical line test, the line will cut the graph once meaning that the graph will form a function

2: 5 minutes because the horizontal line represents that she rested, therefore she was at the park for five minutes

3: 2 minutes because she traveled and reached home between 6 and 8 minutes

What is the least common multiple of 8 and 11

tino4ka555 [31]

Answer:

Step-by-step explanation:

Find the prime factorization of both 8 and 11.

8 → 4 × 2 → 2 × 2 × 2

11 → 11

Then, multiply each factor the greater number of times it occurs. Since no factors are duplicated between 8 and 11 (as in, 2 is not a factor of 11, nor is 11 a factor of 8), LCM will equal 2 × 2 × 2 × 11.

2 × 2 × 2 × 11 = 88, so the LCM is 88.

It's a little hard to explain without visuals. A video could be useful, though I can't put links here.

Calculate how much each size per gram, and circle which gives the best value for money. 250g for $2.30, 400g for &3.40, 1Kg

Bezzdna [24]

To do this, we must set up ratios:
Option One:
$\frac{2.30}{250g} \\ \frac{0.0092}{1g} \\ 0.0092/g$
The first options costs only $0.0092/gram (a fraction of a penny)!
Option Two:
$\frac{3.40}{400g} \\ \frac{0.0085}{1g} \\ 0.0085/g$
The second option costs only $0.0085/gram (cheaper than option one)!
Option Three:
This requires a little more work. First, we have to convert the grams into kilograms. For every 1 kg, there is 1,000 g. Therefore, 1,000g costs $5.65. Next, we set up the ratio as usual:
$\frac{5.65}{1000g} \\ \frac{0.00565}{1g} \\ 0.00565/g$
The third option costs $0.00565/gram.

Therefore, option three is the cheapest!

Hope this helps!
