13
Step-by-step explanation:
The top must be the same length as the total of the bottom
top = 5+8
top = 13
Answer: 76.2
Step-by-step explanation:
Perimetar of isiscales triangle is calculated using equation;
P=b+2a
b=9
P=49
lets find sides of triangle.
P-b=2a
a=(P-b)/2
a=49-9/2
a=40/2=20
If another triangle is similar that means that his base and sides are proportional to first triangle.
Base of first trianlge b₁=9
Base of similar triangle is b₂=14
use proportion to find out side of similar triangle:
b₁:b₂=9:14
a₁:a₂=9:14
a₁=20
20: a₂=9:14
a₂=14*20/9=280/9=31.1
Perimetar of second triangle is:
P₂=b₂+2a₂
P₂=14+2*31.1=14+62.2=76.2
Answer:
the correct answer would be p=nRt/v
Step-by-step explanation:
you would devide both sides by v to get the new equation
Answer:
Penny needs 
cups of flour to make 3/4 of the recipe.
The recipe will make 18 cookies.
Step-by-step explanation:
We have been given that a recipe for oatmeal cookies makes 24 cookies. Penny wants to make 3/4 of the recipe.
To find the number of cookies that will 3/4 of the recipe will make, we need to find 3/4 of 24 as shown below:
Therefore, the recipe will make 18 cookies.
We are also told that recipe calls for 2 1/2 cups of flour. To find amount of flour needed for 3/4 of the recipe, we will multiply 2 1/2 cups by 3/4 as:
Therefore, Penny needs cups of flour to make 3/4 of the recipe.
First, you have to find the common denominators. 2 2/4 and 3 3/4. Next, you have to subtract them. 3 3/4 - 2 2/4= 1 1/4. She will place the sticker 1 1/4 inches away from the edge. I hope it helps ☺️
