by rounding each number to 1 significant figure, estimate the answer to 623 - 14.71 ÷ 0.54.
623 to 1 significant number = 600
14.71 to 1 significant number = 10
0.54 to 1 significant number = 0.5
answer:
[tex]\tt \dfrac{600-10}{0.5}=1180[/tex]
If chicken costs 10¢ per ounce and grain costs 1¢ per ounce, how many ounces of each should
Ruff use in each bag of dog food to minimize cost?
The cost of the chicken and the grain are illustrations of linear programming
The minimized cost is 12¢
How to determine the minimized costRepresent the number of chicken with x and the number of grain with y.
So, the objective function is
Min Z = 10x + y
The constraints are not given.
So, the function cannot be minimized.
However, assume the minimum feasible values of x and y are (1,2), the minimized cost would be:
Z = 10 * 1 + 2
Z = 12
Hence, the minimized cost is 12¢

Michael buys a pair of jeans that regularly costs $62. The jeans were discounted 30%. How much money did Michael pay for the jeans?
Plss help
Answer:
$43.40
Step-by-step explanation:
First, you would have to find out how much was discounted. To find this, you multiply $62.00 (the total) by 30% (the discount sale). You will end up getting $18.60. Finally, you can subtract $18.60 from the original total which was $62.00 to get $43.40 after the discount.

What equation represents the line shown:
Answer: B) y=-3x+2.
Step-by-step explanation:
+2 is where the line touches on the y axis. and for -3. you find 2 points and you go from 1 point to the other. the points i got were. (0,2) (2,-4). i went down 6 times, and to the right 2. that’s a fraction 6/2. and then simplify. 2 can go into 6 three times, and can go into 2 once. 3/1. since there’s a 1 underneath it’s just 3. and since you went down. it’s is negative. so y=-3x+2 is your answer.

The perimeter of a square window is 148 inches. How long is each side?
what is the value of x?
Answer:
x = 10
Step-by-step explanation:
All angles in a triangle must add up to 180. We know one angle is 68 and another is 90 because there is a right angle (which are always 90).
180 = 90 + 68 + (2x + 2)
180 = 158 + (2x + 2). subtract 158 from both sides
22 = 2x + 2. subtract 2 from both sides
20 = 2x. divide both sides by 2
10 = x
Answer:
x = 10
Step-by-step explanation:
2x + 2 + 68 + 90 = 180
2x + 160 = 180
2x = 20
x = 10
Find the value of x. Leave your answer in simplest radical form.
Answer:
First you need to find at least two dimensions of the triangle containing a side length of x. The triangle of the top can be used for that. The hypothenuse for the 7,3 triangle is [tex]\sqrt{58}[/tex].
Now we can use the other triangle with sides of x,[tex]\sqrt{58}[/tex], and a hypothenuse of 9 to find x.
x^2 + [tex]\sqrt{58}^2[/tex] = 9^2
simplify
x^2 + 58 = 81
subtract 58 from both sides
x^2 = 23
x = [tex]\sqrt{23\\}[/tex]
and since this radical cannot be simplified further that is your answer.
Step-by-step explanation:
Step-by-step explanation:
Pythagoras.
c² = a² + b²
c being the Hypotenuse (the side opposite of the right angle).
so, the length of the rectangle is the Hypotenuse of the right-angled triangle on the top :
length² = 7² + 3² = 49 + 9 = 58
length = sqrt(58)
the diagonal of the rectangle is again the Hypotenuse of the right-angled triangle of length (sqrt(58)), width (x) and diagonal (9) of the rectangle.
so, we have
9² = sqrt(58)² + x² = 58 + x²
81 = 58 + x²
23 = x²
x = sqrt(23)
Solve for x. Round to the nearest tenth of a degree, if necessary.

T

U
Use law of sines:
Cos(x) = adjacent/ hypotenuse
cos(x) = 8.8/13
X = arcsin(8.8/13)
X = 47.396 degrees
Rounded to the nearest tenth = 37.4 degrees

Write the inequality:
Two less than twice a number is less than a half.
Answer:
2x-2<1/2
Step-by-step explanation:
when the problem says "two less than" it means we are subtracting 2 from something, in this case, that something is "twice a number" as the problem states. So we would write 2x where x is a variable that represents any number so we have 2x-2<1/2.

In a school 50% of the students are younger than 10, 1/20 are 10 years old and 1/10 are older than 10 but younger than 12, the remaining 70 students are 12 years or older. How many students are 10 years old?
Answer:
10 students
Step-by-step explanation:
Given :-
50% younger than 10
1/20 (or 5%) are 10
1/10 (or 10%) are older than 10 but younger than 12
Remaining students = 100% - 50% - 10% - 5%
= 35%
= 70 students
Total students
=> 7T/20 = 70
=> 7T = 1400
=> T = 200
10 year old students
= T x 5%
= 200 x 1/20
= 10 students
Given :
[tex]50\%[/tex]younger than [tex]10[/tex]
[tex]\frac{1}{20} [/tex](or 5%) are 10
[tex]\frac{1}{10}[/tex] (or 10%) are older than 10 but younger than 12

Answer:
x = 11
Step-by-step explanation:
(3x + 28) + (5x + 52) + ( 2x - 10) = 180
(3x + 5x + 2x) + (28 + 52 - 10) = 180
10x + 70 = 180
10x = 180 - 70
10x = 110
x = 11
Answer:
x= 11
Step-by-step explanation:
(3x + 5x) + (5x+52) + (2x-10)= 180 (sum of anglea in a triangle)
10x+80-10= 180
10x+70=180
10x=180-70
10x=110
x=110÷10
x=11

Anna selects a positive multiple of 4 that is less than forty, and Becky selects a positive multiple of 3 that is less than sixty. What is the probability that they pick the same number?
I will mark brainliest!
Answer:
3/171
Step-by-step explanation:
The problem can be simplified into finding probability that Anna and Becky select 12 or 24 or 36 which are less than 40 and multiples of 3 and 4.
Probability of Anna selecting 12 = 1/9
Probability of Becky selecting 12 = 1/19
Probability of Anna and Becky selecting 12 = 1/9 * 1/19 = 1/171
Probability of Anna and Becky selecting 12 or 24 or 36 = 3* 1/171 = 3/171
