An equilateral triangle has sides of length 10 cm.
**DIAGRAM IN PICTURE**
a. Calculate the perpendicular height, h, of the triangle.
b. Calculate the area of the triangle.
Give your answers correct to one decimal place. 10 cm 10 cm 10 cm
Answer:
a. 8.7cm
b. 43.5cm squared
Step-by-step explanation:
a. draw the triangle with a side length of 10cm, and measure the height which is 8.7cm.
b. formula to find the area of a triangle: (base into height) divided by 2 ((b x h) / 2)
the base is 10
the height is 8.7
(10 x 8.7)/2 = 87/2 = 43.5 cm squared

Step-by-step explanation:
0.25(4x - 24) + x = 14
x - 6 + x = 14
2x - 6 = 14
2x - 6 + 6 = 14 + 6
2x = 20
2x ÷ 2 = 20 ÷ 2
x = 10

A picnic basket was marked up 95% from an original cost of $9.57. Last Friday, Rosanne bought the picnic basket and paid an additional 8% in sales tax. What was her total cost?
Answer: $10.60
Step-by-step explanation:
Turn 95% into a decimal then add $9.57, then turn 8% into a decimal then add all of the numbers together.
I'm not sure if this is right, I did it on my own.
The total cost to be paid is $20.15
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
Original cost = $9.57
Markup= 95%
So, the new cost of the basket
=95/100 x 9.57
=0.95 x 9.57
=$9.0915
Thus, the cost of the basket is
= 9.57+9.0915
=18.66
Also, the sales tax is 8%
=8/100 x 18.66
=0.08 x 18.66
=1.4928
Therefore, the total amount to be paid is
=18.66+1.4928
=$20.15

Answer:
F
Step-by-step explanation:
So lets use the process of elimantion to find the answer.
Firs off, we can tell that this is a greater/less than or equal to inequlaity, since there is a inclosed circle, not a open one. So this leaves the top left answer and bottem right answer.
Now, we can see that the graph is from 0-15. X is at 7.
This means its x+8, because the x would be smaller, or possibly even negatibe on this graph.
My theory that can better support my annwer is if we solve for x:
x+8=15
We can subtract 8 from both sides:
x=7
And as we can see on the inequality, x is at 7 in the graph.
Hope this makes sense and helps!

Answer:
75 in
Step-by-step explanation:
Answer:
I think the actual length would be 75 inches. ( i'm not totally sure though C: )
Step-by-step explanation:
So, since the scale factor is 1 : 12, the model is 1/12 of the actual. So, multiply:
6.25 * 12 = 75
So, the actual length would be 75 inches.
To check:
75/6.25 = 12!

F. 3h-2<≤4
G. 3h+2≤14
H. 3H-2≥14
J. 3h+2≥14
Answer:
3H - 2 ≤ 14 I believe.
If i'm wrong forgive me
Answer:
G: 3h+2[tex]\leq \\[/tex]14
Step-by-step explanation:
He could've spent 14 dollars, or less, so the sign is the less than, equal to sign. The 3h represents the cost of hot dogs times the number of hot dogs. The represents the cost of the water bottle. It is addition because he purchased both the water bottle and hot dogs.
