Every week Sam saves $1.00 on Monday and $2.50 on Friday. If this is his total weekly savings, how many weeks
would it take him to save enough to buy a $49 wireless phone?
14 weeks
D 46 weeks
E 7 weeks
0 52 weeks
What is the answer
Answer:
14 weeks
Step-by-step explanation:
He earns $3.50 a week, so he would need to save up for 14 weeks to get enough money
Hope this helped!
Stay safe! <3
Answer:
14 weeks
Step-by-step explanation:
Hello kenzieshirley, this question can be easily solved by setting up and equation.
To start we can say that in total Sam will be saving $3.50 every week
$1.50 + $2.50 = $3.50
Then we can set up a linear equation:
y = 3.50x
where y = total amount saved, x = weeks
then all we have to do is substitute $49 for y, as we want to know how many weeks, x, it will take to save up for Sam's phone.
49 = 3.5x
x=14
It will take Sam 14 weeks to save up $49
Hope this helps!

Enter a number in each box so that the expressions are equivalent. (A) 0.8 (2x + x) + 3(7 - 4.1x) = x + 21 (B) 12 1 2 (6x + 22y) = x + y (C) (3x - ) - (6x + 1) = -3x - 2 (D) 112 1 2 x + 27y = (12 1 2 x + 9y)
The questions aren't well formatted ; from the values that are observable,
Answer:
Coefficient of x = -9.9 ;
Coefficient of x = 75
Coefficient of y = 275
Step-by-step explanation:
Given :
0.8 (2x + x) + 3(7 - 4.1x) = __x + 21
0.8(3x) + 21 - 12.3x = __x + 21
2.4x + 21 - 12.3x = __x + 21
-9.9x + 21 = __x + 21
-9.9
12 1/2 (6x + 22y) = x + y
75x + 275y = x + y
Answer:
The answers are:
1. -9.9x
2. 3x + 11y
3. 1
4. 3

What is probability?probability is the ratio of the number of favorable outcomes and the total number of possible outcomes. The chance that a particular event (or set of events) will occur expressed on a linear scale from 0 (impossibility) to 1 (certainty), also expressed as a percentage between 0 and 100%.

A biased estimator is one that deviates from the true population value. A biased sample can still be useful if the nature of the bias and how much of a bias exists is known.
An unbiased estimator is when a value from a sample is the same as the actual value of a population parameter.
The sample is not chosen at random, the inherent bias in convenience sampling means that the sample is unlikely to be representative of the population being studied. This undermines your ability to make generalizations from your sample to the population you are studying.
Therefore, the sample of the assigned reading likely to be biased and convenience sample.

Evaluate the expression when a – 3 and c = 12
[tex] \frac{ c}{a} \: = [/tex]
Answer:
4
Step-by-step explanation:
First, let's replace the c with 12, and the a with 3, since those are the values given.
Now we have 12/3.
12 ÷ 3 = 4
So, c/a = 4.

If the wholesale price of a pair of shoes is $32.00, and the markup is 55%, find the selling price of the item.
Answer:
$49.6
Step-by-step explanation:
Given that :
Wholesale price, p = $32
Markup percentage = 55%
Selling price = wholesale price * ( 1 + Markup percentage)
Selling price = $32(1 + 0.55)
Selling price = $32(1.55)
Selling price = $49.6

Given 6, 8, and 11 as the three sides of a triangle, classify it as one of the following:
A. Acute
B. Right
C. Obtuse
9514 1404 393
Answer:
C. Obtuse
Step-by-step explanation:
The "form factor" I use for this is ...
a^2 + b^2 - c^2 = 6^2 + 8^2 - 11^2 = 36 +64 -121 = -21
The value is negative, indicating an OBTUSE triangle.
__
Additional comment
In this expression, 'a' and 'b' are the two shortest sides (in no particular order) and 'c' is the longest side. The interpretation is ...
negative — obtuse
zero — right
positive — acute
__
If you're familiar with Pythagorean triples, you know that the 3-4-5 right triangle triple can be doubled to give 6-8-10. The long side of 11 is longer than the hypotenuse for the right triangle, so would correspond to a largest angle greater than 90°. The 6-8-11 triangle would be OBTUSE.
