What is the area of a right triangle with a height of 8.9cm and a base of 14.3cm?
Answer:
ar of triangke is 1 /2 base*height
so
ar = 1/2 * 8.9*14.3
ans = 63.63 sq cm
Answer: 63.63cm
Step-by-step explanation: To find the area for a triangle, the formula is A=L*W divided by 2. So you want to do A=14.3*8.9/2= 63.63500 (63.63).
Have a good day.
Answer this for me!!
Answer:
A = 48 cm²
Step-by-step explanation:
This figure can be thought of as a rectangle 4 cm by 8 cm in the middle and one triangle on the left side and a congruent triangle on the right side. The triangles have 8 cm bas and 2 cm height.
total area = area of rectangle + 2 × area of triangle
total area = (4 cm)(8 cm) + 2 × (8 cm)(2 cm)/2
total area = 48 cm²
Nayeli went shopping for a new video game because of a sale. The store was offering a 45% discount. If the price on the tag was $44, what would be the price after the discount but before tax, to the nearest dollar and cent?
Answer:
Step-by-step explanation:
45 % discount means 55/100.
55/100 x $44
simplify
0.55 x 44
= (5 x 44) + (50 x 44)
() = 220
220 +?
() = 2200
220 + 2200 = 2420
move the decimal back, and then... $24.20

Find the volume of the pyramid. Round to the nearest tenth if necessary.
Answer:
410.6 cubic cm
Step-by-step explanation:
Formula V = (l x w x h) / 3
V = ( 8 x 14 x 11) / 3
V = 1232 / 3
V = 410.6 cubic cm
The variables y and x have a proportional relationship, and y = 7 when x = 2.
What is the value of y when x = 5?
Enter your answer as a decimal in the box.
y = ___
Answer:
17.5
Step-by-step explanation:
x=2
y=7
when y by x, then multiple y by 5.
7/2= 3.5
3.5×5= 17.5
you can also do 7x2 which would give you 14 and then divide 7 by 2 to get 3.5, and add the two together, so 14+3.5=17.

PLEASE HELP ME :DDDDDDDDDDDDDD
Answer:
Step-by-step explanation:
To find the area of a rectangle, you multiply the length by the height.
First, we need to convert the mixed numbers to improper fractions:
Length: 6 3/4 ft = (6 x 4 + 3) / 4 ft = 27 / 4 ft
Height: 2 2/12 ft = (2 x 12 + 2) / 12 ft = 26 / 12 ft = 13 / 6 ft
Now we can calculate the area:
Area = Length x Height
Area = (27 / 4) ft x (13 / 6) ft
Area = 351 / 24 ft^2
Area = 14 11/24 ft^2
Therefore, the area of the rectangle is 14 11/24 square feet.

A pet store specializes in exotic fish. The graph shows a proportional relationship between the number of fish and the number of fish tanks at the store. Fish 65 52 39 26 13 0 1 2 3 4 Fish Tanks 5 6 X The constant of proportionality shown in the graph in terms of the number of fish per fish tank is
Answer:
13
Step-by-step explanation:
if there are 5 tanks and 65 fish in all the tanks together, you take 65 and divide it by 5 to get 13 fish in each tank
: )
Answer:
10.84.
Step-by-step explanation:
To find the constant of proportionality, we can use the fact that the relationship between the number of fish and fish tanks is proportional. This means that the ratio of the number of fish to the number of fish tanks is always the same.
From the graph, we can see that when there are 65 fish, there are 5 fish tanks. When there are 52 fish, there are 6 fish tanks. Let's use these two data points to find the constant of proportionality:
The constant of proportionality = (Number of fish) / (Number of fish tanks)
For the first data point, we have:
65 / 5 = 13
For the second data point, we have:
52 / 6 = 8.67
We can see that these two values are not the same, which means that the relationship between the number of fish and the number of fish tanks is not exactly proportional. However, we can still find an average constant of proportionality between these two values:
(13 + 8.67) / 2 = 10.84
So the constant of proportionality, in terms of the number of fish per fish tank, is approximately 10.84.
