Gina and Glen share a 24-ounce bucket of clay. By the end of the week, Gina has used
5/8
of the bucket, and Glen has used
1/4
of the bucket of clay. How many ounces are left in the bucket?
Answer: 3 ounces
Step-by-step explanation:
1/4=2/8
5/8 + 2/8 = 7/8
7/8 = x/24
8x3= 24
7x3=21
24-21=3
Answer:
3 ounces remain
Step-by-step explanation:
5/8 + 1/4 = ?
5/8 + 2/8 = ? (find common denominators)
= 7/8 of the bucket
7/8 = ?/24 (trying to find how many ounces is 7/8 of the bucket)
7/8 = 21/24 (multiple 7 with 3)
24 - 21 = ? (trying to find how many ounces are left)
= 3 ounces

Answer:
40
Step-by-step explanation:
if the ratio from men to woman is 4:5 and men are 32 that means w need to find a way to get to 32 using 4 and 8 x 4 is 32. so if we use 8 to get to 32 we need to use 8 on 5 aswell for it to be an equal ratio.
PLEASE HELP!!!!
solve for x.
5 x =5x because 2 turns to 3 so 3 turns to 5
Students surveyed boys and girls separately to determine which sport was enjoyed the most.

• The girl survey had a ratio of the number of girls who enjoyed soccer to the number of girls
who enjoyed basketball of 5:3.
If the same number of boys and girls were surveyed, and 45 girls enjoy soccer, how many boys
enjoy each sport?

I'm not sure how to find the unknown angle
Answer:
x=82
Step-by-step explanation:
All triangles have interior angles that add up to 180 Degrees.
We already know one of the angles, and the other two are the same.
180-16=164
164/2=82
Answer:
x=82
Step-by-step explanation:
well it's an isosceles triangle(two sides of the same lenght) which means that the angles between these 2 sides and the 3rd one are also equal. 2x=180-16 x=82
I need help on this..
Answer:
x^3 + 3 (the third option)
Step-by-step explanation:
In this question, we are asked to find the missing value inside the parenthesis.
x^8 +3x^5 = x^5(____)
We see that x^5 is factored out of the original expression, so we can obtain the answer by dividing both terms by x^5.
x^8 / x^5 = x^3
3x^5/ x^5 = 3
So we have: x^3 + 3.

If h(x) = 6 – x, what is the value of (h circle h) (10)?
–4
–2
10
16
Answer:
10
Step-by-step explanation:
To get this, we get h circle h (10)
we start by getting h circle h
That simply means placing h in h
we have this as:
6-(6-x)
= 6-6 + x = x
Next here is to find h circle h (10)
We simply replace x by 10 here so we have 10 as the answer

how to find the perimeter of the triangle ?
Answer:
5.448
5.450 (simplified)
Step-by-step explanation:
since it is a right triangle one of the angle is 90 degrees
first angle = 31
second angle = 90
first side = 5
use sines
perimeter = 5 + [5 / sin(31 + 30)] * [sin(31) + sin(90)] = 5.448
Please help almost due!!!!!!!!!!
Step-by-step explanation:
Let's finish strong! Maybe we'll have some time for some fun activities!
Let's start with angle B.
Remember that the internal angle of a triangle will always equal 180.
We have a rignt angle (90), a known angle (54), and unknown B.
We can establish a simple equation to solve for B. [tex]B = 180 - 90 - 54[/tex]
33% done!
To solve for the other sides of the triangle, we'll need to use our trig functions! Boo! I know, but they are super handy! Let's see them in action.
Remember that ol' saying - some old hippy caught another hippy tripping on acid. SOH, CAH, TOA.
sin = opposite over hypotenuse, cos = adjacent over hypotenuse, tan = opposite over adjacent. [tex]tan(54) = a/23[/tex]
A little fancy calculator work and we're 66% done! whew!
If we know a and the third side as being 23, we can just use the Pythagorean theorem
[tex]c^2 = a^2 + b^2[/tex]
Done! Wow! That's feels good. Great job!

The music teacher receives 9 boxes of recorders there are six recorders in each box she hands them out to third graders and has 5recorders left how many third graders received a recorder
Answer:
49 third graders
Step-by-step explanation:
From the question:
The music teacher receives 9 boxes of recorders and there are six recorders in each box
The total number of recorders the teacher received =
1 box = 6 recorders
9 boxes = x
Cross Multiply
x = 9 × 6 recorders
x = 54 recorders.
She hands them out to third graders and has 5recorders left .
How many third graders received a recorder?
The amount of recorders shared =
54 recorders - 5 recorders
= 49 recorders
If 1 recorders was given to a third grader,
Therefore, the amount of third graders that received a recorder is 49 third graders

-3=x/-9 please tell me how to solve this I’m way behind and trying to learn thank you :)
-3 = x/-9
To make this easier, I'll put it in normal numbers
(-3 = x/-9) -1
3 = x/9
Multiply both sides by nine to take out the division.
27 = x
Hope that this helped!
