Answer:
37 beads
Step-by-step explanation:
Given that:
Adel : Claire = 7 : 4
Let Adel be = A; &
Let Claire be = C
A: C = 7 : 4
[tex]\dfrac{A}{C} =\dfrac{7}{4}[/tex]
7C = 4A
[tex]C = \dfrac{4A}{7}[/tex] --- (1)
When Adel gave 68 beads to claire, we have:
C + 68 = 25:41
[tex]\dfrac{A}{C+68}= \dfrac{25}{41}[/tex]
25(C + 68) = 41A
C + 68 = [tex]\dfrac{41}{25}A[/tex]
[tex]C = \dfrac{41}{25}A - 68[/tex] --- (2)
Equating (1) and (2) together;
[tex]\dfrac{4 * A}{7} = \dfrac{41 *A}{25} - 68[/tex]
[tex]\dfrac{4 * A}{7}-\dfrac{41 *A}{25} = - 68[/tex]
[tex]\dfrac{100A - 287 A}{175} =- 68[/tex]
[tex]\dfrac{-187A}{175} = -68[/tex]
- 187 A = 175 × (-68)
-187 A = - 11900
A = - 11900/ -187
A ≅ 64
From; [tex]C = \dfrac{4A}{7}[/tex]
[tex]C = \dfrac{4*64}{7}[/tex]
C = 36.57
C ≅ 37 beads
How do I solve this equation?
Answer:
x=14
Step-by-step explanation:
Hope This Helps!
Answer:
x = 22/3, x=14
Step-by-step explanation:
Start by isolating whatever is in the absolute value sign; in this case divide either side by 4
4|1-3/4x + 7| =10,
----------------- ----
4 4
|1-3/4x + 7| = 10/4 = 5/2,
now if we apply the absolute value rule we know that 1-3/4x + 7 will be equal to -5/2, and 5/2
1-3/4x + 7 = 5/2 and 1-3/4x + 7 = -5/2
-3/4x + 8 = 5/2,
-3/4x=5/2-8,
-3/4x = 5/2-16/2,
-3/4x = -11/2,
x = -11/2*-4/3 = 44/6 = 22/3
-3/4x+8 = -5/2
-3/4x = -5/2-8
-3/4x = -5/2-16/2
-3/4x = -21/2
x = -21/2*-4/3 = 82/6 = 14

Complete the real-world situation that could be modeled by the equation 150 − 8x = 170 − 12x. Xavier has $150 in his lunch account. He spends $ for lunch each day. Zack has $ in his lunch account. He spends $ each day. After how many days will the boys have the same amount of money in their accounts?
Answer:
5 days
Step-by-step explanation:
The question above is modeled by the equation :
150 − 8x = 170 − 12x.
After how many days will both have ye same amount :
Number of days = x
Collect like terms
-8x + 12x = 170 - 150
4x = 20
x = 20/4
x = 5 days
The boys will have the same amount in their account after 5 days.
Suppose 123 people voted for Danny. If 55 of the votes were from girls, what would be the ratio of votes from girls to votes from boys? Explain.
55:86
Step-by-step explanation:
86+55=123 so ratio is from girls to boys
Answer: 55:68
Explanation:
This ratio compares part-to-part, or the number of votes from girls to the number of votes from boys. If 123 people voted for Danny and 55 of those votes were from girls, then 68 votes were from boys. The ratio would be 55:68.

the base of a triangle is 7 less than twice its height. If the area of the triangle is 102m^2, find the length of the base.
Answer:
The length of the base will be: 17 m
Step-by-step explanation:
Given the area of the triangle
[tex]A=102\:m^2[/tex]
Using the formula of Area of a triangle:
[tex]A=\frac{1}{2}\left(b\times h\right)[/tex]
Here,
'b' is the base'h' is the heightAs the base of a triangle is 7 less than twice its height.
so
[tex]b=2h-7[/tex]
so the formula of Area of a triangle becomes
[tex]102=\frac{1}{2}\left(\left(2h-7\right)\times \:h\right)[/tex]
[tex]204=h\left(2h-7\right)[/tex]
[tex]2h^2-7h=204[/tex]
[tex]2h^2-7h-204=0[/tex]
[tex]\left(2h+17\right)\left(h-12\right)=0[/tex]
[tex]2h+17=0\quad \mathrm{or}\quad \:h-12=0[/tex]
[tex]h=-\frac{17}{2},\:h=12[/tex]
As height can not be negative, so:
[tex]h=12[/tex] m
Hence, the length of the base:
[tex]b=2h-7[/tex]
[tex]= 2(12)-7[/tex]
[tex]=24-7[/tex]
[tex]= 17[/tex] m
Therefore, the length of the base will be: 17 m
Can somebody explain how to do this
Answer:
The answer is 46.
Step-by-step explanation:
First, you will have to add up both functions in order to find the new expression for (g + f)(a) :
g(a) + f(a) = (g + f)(a)
(g + f)(a) = 3a + 3 + 2a - 2
(g + f)(a) = 5a + 1
Next, you have to substitute a = 9 into the function :
(g + f)(9) = 5(9) + 1
(g + f)(9) = 46

Does anyone have the answer key to these proofs? They are Mrs. E Teaches Math introductory proofs. There are 14 total. I've done 1-9.
Statement 1: 2AB = AC
Reason 1: Given
--------------------------------------------
Statement 2: AC = AB+BC
Reason 2: Segment addition postulate (which your teacher abbreviated to "Seg + Post")
--------------------------------------------
Statement 3: 2AB = AB+BC
Reason 3: Substitution
--------------------------------------------
Statement 4: 2AB-AB = AB+BC-AB
Reason 4: Subtraction Property of Equality
---------------------------------------------
Statement 5: AB = BC
Reason 5: Combine like terms
----------------------------------------------
Notes:
The first reason is "given" since we just simply restate what the instructions provide. If you are given multiple items, you list each one at a time. The segment addition postulate is where we break a line into smaller parts and then build it back together.Substitution is simply replacement. We've replaced AC with 2AB.The subtraction property of equality is the idea where we subtract the same thing from both sides. In statement 4, we're subtracting AB from both sides.The last statement of any proof is always the thing we're trying to prove. Once we reach such a statement, there's no need to go any further since the proof has concluded.Taylor can clean pools at a constant rate of 25 pools per hour. How many pools can Taylor clean in 25 hours?
Taylor can clean 625 pools in 25 hours
If Taylor can clean pools at a constant rate of 25 pools per hour, this is expressed as:
25 pools = 1hour
We are to calculate the number of pools that Taylor can clean in 25 hours, this is expressed as;
x = 25 hours
Divide both expressions
25/x = 1/25
x = 25 * 25
x = 625 pools
Hence Taylor can clean 625 pools in 25 hours

Definition of a random sample
Answer:
Step-by-step explanation:
In statistics, a simple random sample is a subset of individuals (a sample) chosen from a larger set (a population). Each individual is chosen randomly and entirely by chance, such that each individual has the same probability of being chosen at any stage during the sampling process, and each subset of k individuals has the same probability of being chosen for the sample as any other subset of k.
Answer:
Step-by-step explanation:
random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen. A simple random sample is meant to be an unbiased representation of a group.

Answer:
4 btw lovinggg the M !!!!!
Step-by-step explanation:
Answer:
Undefined
Step-by-step explanation:
To find slope, you need the difference of y over the difference of x.
For example, let's use (-8,8) and (-8,3).
Difference of y: 8-3
Difference of x: -8-(-8) (Note that the order of the x values must be the same as the order of the corresponding y values of the coordinate)
(8-3)/(-8+8)
= 5/0
Now, we see that we have to divide by 0, except it's impossible to divide by 0, so the slope is left as undefined.
