Pepay had 0.37 inches of yarn, Riza had 0.45 inch of yarn too. Their friend Lala asked to borrow 0.25 inch of yarn that they have. What is the length of the remaining yarn?
Answer:
0.57 inches was left
Step-by-step explanation:
Here, we start by calculating the total length of the yam they have
Mathematically, that will be 0.37 + 0.45 = 0.82 inch
Now, to get what is remaining, we subtract what was borrowed
Mathematically, that is 0.82-0.25 = 0.57 inches

Answer:
Slope is 1/2
Step-by-step explanation:
Use the slope formula. Say S = the 1st point and T = the 2nd point.
m = 20 - 10 10 1
------------ = ----------- = ---
20 - 0 20 2
The equation for slope is also y = mx + b
m is the slope, b is the y-intercept.
Therefore, if you look at the 1st choice, you can see that 1/2 is in the place of m, meaning that 1/2 is the slope of line ST
I dunno how to do the other way
I really need help I don’t know what todo I will do anything to get the best answer.(if u do 20 I will give 100 points and brain list on next question)!!YOU DONT HAVE TO DO 19 ONLY 17 18 AND 20!!
Answer:
20.) Some charateristics to look for are "what's its leaf shape?" , "does this plant have spores?" , "does it have no leaves?" and "is it a vascular or non-vascular plant?". By naming its charateristics we can infer that it must be a fungus. This means its root system attaches to other plant roots in order to get nutrients for itself.
18.) If we observe the charateristics of the moss we might get an answer. Moss needs water in order to survive since it is the source of nutrients for the moss. The reason why the moss turned green after the rainstorm was because it got the nutrients it needed so it caused the moss to flourish again.
17.) We can use models to compare and contrast plant and fungus cells. By using evidence we can include that both the plant and fungus cells have some common characteristics, however plants are autotrophic, making their own energy, and have cell walls made of cellulose, but fungi are heterotrophic taking in food for energy and have cell walls made of chitin.

Ade is baking mini-loaves of bread. How many mini-loaves could he make with 10 cups of flour?
Answer: 25
Step-by-step explanation:
Since Ade uses 2 cups of flours for 5 mini loaves, it simply means that 1 cup of flour will be used for:
= 5/2 = 2.5 mini loaves
Therefore, the number of mini-loaves that he could make with 10 cups of flour would be:
= 10 × 2.5
= 25 mini loaves
Two friends are going to the mall to buy pizza. One of the friends buys 1cheese slice and 2 pepperoni slices for $8.75. Her friend purchases 2 chese slices and 3 pepperoni slices for $15.00. Find the cost of each.
Answer:
The cost of each:
1 cheese slice = c = $3.75
1 pepperoni slice = p = $2.5
Step-by-step explanation:
Let the cost:
1 cheese slice = c
1 pepperoni slice = p
Two friends are going to the mall to buy pizza.
One of the friends buys 1cheese slice and 2 pepperoni slices for $8.75.
c + 2p = $8.75.....Equation 1
c = $8.75 - 2p
Her friend purchases 2 chese slices and 3 pepperoni slices for $15.00.
2c + 3p = $15.00.....Equation 2
We substitute 8.75 - 2p for c in Equation 2
2(8.75 - 2p) + 3p = $15.00
17.5 - 4p + 3p = 15
Collect like terms
- 4p + 3p = 15 - 17.5
-p = -2.5
p = $2.5
c = $8.75 - 2p
c = $8.75 - 2(2.5)
c = $8.75 - 5.0
c = $3.75
The cost of each:
1 cheese slice = c = $3.75
1 pepperoni slice = p = $2.5
The perimeter of a square is equal to the perimeter of an equilateral triangle. The length of a side of the square is given by x, and the length of a side of the equilateral triangle is given by x + 1. Which equation can be used to find the value of x?
x = 3 (x + 1)
3 x = 4 (x + 1)
4 x = 3 (x + 1)
x = x + 1
Answer:
4x=3(x+1)

Given sin 0 = { and angle 0 is in Quadrant II, what is the exact value of cos 0 in
simplest form? Simplify all radicals if needed.
Answer:
Sin0= y/r
X= -4 and r= 9 (radius is also the hypotenuse)
In quadrant II y is positive
X^2 +y^2 = r^2
-4^2 + y^2 = 9^2
16 + y^2 = 81
Y^2 = 81-16
Y^2 = 65
Y= sqrt65
Sin0= sqrt65/9

A piece of green rope is being used to make a border around the outside of a sculpture that is in the shape of an equilateral triangle. One side of the equilateral triangle has a length of 3x + 3. Give TWO equivalent expressions that can be used to represent the length of the rope that is used to border all 3 sides.
Answer:
The equivalent expressions are;
9x + 9
and
9(x + 1)
Step-by-step explanation:
Mathematically, we should understand that an equilateral triangle has all of its sides equal
So if one side is 3x+ 3, the other sides too measures same
Therefore, the length of the rope represents the perimeter of the triangle
This is obtainable by adding all the side lengths together
This will be;
3x + 3 + 3x + 3 + 3x + 3 = 9x + 9
This is also same as 9(x + 1)

y=2/3x+3
y=3/2x+3
y=3/2x−3
y=2/3x−3
Answer:
y= 3/2x-3
Step-by-step explanation:
m= y2-y1/x2-x1
m= -6-(-9)/-4-(-2)
m= 3/2
y= mx+b
y= 3/2x+b
-9=3/2*-6+b

Nate walks 3/5 mile in 1/2 hour. How fast did he walk, in miles per hours
Answer:
1 1/5 miles per hour
Step-by-step explanation:
multiply 3/5 and 1/2 and then you would get your answer
Speed = distance/ time
speed = 3/5 ÷ 1/2
speed = 3/5*2
speed = 6/5mph or 1.2 mph

Step-by-step explanation:
Lateral Surface Area of a Cone
Given a right circular cone of base radius r and height h, the lateral surface area is given by:
[tex]A=\pi r\sqrt{r^2+h^2}[/tex]
We are given the lateral area of a funnel as A=236.64 square cm and the radius is r=4.75 cm. It's required to find the height of the cone. It can be calculated by solving for h.
Squaring:
[tex]A^2=\pi^2 r^2(r^2+h^2)[/tex]
Dividing by [tex]\pi r^2[/tex]
[tex]\displaystyle \frac{A^2}{\pi^2 r^2}=r^2+h^2[/tex]
Subtracting [tex]r^2[/tex]:
[tex]\displaystyle \frac{A^2}{\pi^2 r^2}-r^2=h^2[/tex]
Taking square root:
[tex]\displaystyle h=\sqrt{ \frac{A^2}{\pi^2 r^2}-r^2}[/tex]
Substituting the values:
[tex]\displaystyle h=\sqrt{ 251.472-22.5625}[/tex]
[tex]\displaystyle h=\sqrt{ 228.909}[/tex]
h = 15.13 cm
