PLS HURRY NOWWWW. Peanuts are priced at $3.38 per pound. Derek buys a sack
of peanuts for $15.82. Which measurement is a reasonable
estimate of the weight of the peanuts that are in the sack?
A А
70 lb
B
5 lb
C
50 lb
D 7 lb
Answer:
a 70
Step-by-step explanation:
eanuts have a high oil content (45 percent to 52 percent) compared to several other oilseed crops. With a yield of 3,000 pounds per acre, a 70 grade (70 percent of the weight of the peanut in shell) and 50 percent oil content, peanuts could potentially produce 120 to 150 gallons of biodiesel per acre.

Kyle is raising money for his school. He has $75 saved and needs to raise at least $150. He wrote part of an inequality to help him find the minimum amount of money needed to raise. Which inequality symbol can be used in the box to make this inequality correct?
≥
Answer: >_
Step-by-step explanation:
The symbol for inequality is represented as "≥".
Given data:
To find the minimum amount of money Kyle needs to raise, the inequality is determined as:
Kyle already has $75 saved, and he needs to raise at least $150.
Let's represent the minimum amount he needs to raise with the variable "x."
The inequality can be written as:
$75 + x ≥ $150
In this inequality, we are adding the amount Kyle has saved ($75) to the amount he needs to raise (x), and it should be greater than or equal to $150.
To indicate that the left side of the inequality should be greater than or equal to the right side, we use the symbol "≥" in the box.
Hence, the correct inequality symbol to make the inequality accurate is "≥".

Step-by-step explanation:
Here are measurements (in millime- ters) of a critical dimension on an SRS of 16 of the more than 200 auto engine crankshafts produced in one day: 224.120 224.001 224.017 223.982 223.989 223.961 223.960 224.089 223.987 223.976 223.902 223.980 224.098 224.057 223.913 223.999 (a) Construct and interpret a 95% confidence interval for the process mean at the time these crankshafts were produced.
Answer:
(23.97, 24.03)
Step-by-step explanation:
Given the data:
224.120 224.001 224.017 223.982 223.989 223.961 223.960 224.089 223.987 223.976 223.902 223.980 224.098 224.057 223.913 223.999
Confidence interval = m ± Zcritical(s/√n)
n = sample size = 16
Zcritical at 95% = 1.96
Using calculator :
Sample mean, m = 224.0019
Standard deviation, s = 0.0618
Lower bound : 24.0019 - 1.96(0.0618/√16) = 23.971618
Upper bound : 24.0019 + 1.96(0.0618/√16) = 24.032182

Angle BAC and Angle FAC are examples of what type of angle pair? (1 point)
Angle BCE and Angle DCA are examples of what type of angle pair? (1 point)
Answer:
Answer:
Try this option, note: only calculation is performed, the last two question are missed.
Step-by-step explanation:
to calculate 'x':
the rule: m∠BAC+m∠ABC+m∠BCA=180°; if to substitute m∠BAC=4x+10,m∠ABC=12x-6,and m∠BCA=3x+5, then 4x+10+12x-6+3x+5=180°; ⇔ x=9.
to calculate m∠BAC; m∠ABC; m∠BCA:
m∠BAC=4x+10; ⇒ m∠BAC=36+10=46°;
m∠ABC=12x-6; ⇒ m∠ABC=108-6=102°;
and m∠BCA=3x+5; ⇒ m∠BCA=27+5=32°.
to calculate the angle 1 and 2:
the fule is: m∠1+m∠BAC=180° and m∠2+m∠ABC=180°.
Then m∠1=180-m∠BAC=180-46=134°;
m∠2=180-m∠ABC=180-102=78°.

5x - y + z = -6
2x + 7y + 3z = 8
x + 2z = 6
Answer:
Step-by-step explanation:
The system of equations given are:
5x - y + z = -6 ------------- i
2x + 7y + 3z = 8 ---------- ii
x + 2z = 6 ----------------- iii
Let us deal with equation i and ii first since they have 3 variables x, y and z;
5x - y + z = -6 x 7
2x + 7y + 3z = 8 x 1
35x - 7y + 7z = -42 ---- iv
2x + 7y + 3z = 8 ---- v
Add equation iv and v;
37x + 10z = -34 ------vi
So, let us solve equation vi and iii:
x + 2z = 6 - ---------- iii x 10
37x + 10z = -34 --- iv x 2
10x + 20z = 60 vi
74x + 20z = -68 vii
Subtract vi - vii;
-64x = 128
x = -2
So; put x = -2 into iii;
x + 2z = 6
-2 + 2z = 6
2z = 6 + 2 = 8
z = 4
Put x = -2 and z = 4 into equation i;
5(-2) - y + 4 = - 6
-10 -y +4 = -6
-6 - y = -6
-y = 0
y = 0

In the first week of July a record 1120 people went to the local swimming pool in the second week 105 fewer people went to the pool then in the first week in the third week 135 more people went to the pool then in the second week in the first week 310 fewer people went to the pool then in the third week what is the percent decrease in the number of people who went to the pool over these four weeks
Answer:
25%
Step-by-step explanation:
The number of people who went to the local swimming pool in the;
first week = 1120
second week ( 105 fewer people) = 1120 - 105 = 1015
third week (135 more people) = 1015 + 135 = 1150
fourth week (310 fewer people|) = 1150 - 310 = 840
The percent decrease in the number of people who went to the pool over these four weeks
= (1120 - 840)/1120 * 100%
= 280/1120 * 100%
= 1/4 * 100%
= 25%
It means that the number of people who went to the local swimming pool over the 4 weeks decreased by 25%

Either a tangent line or a line parallel to the axis of symmetry will do.
A standard high school parabola has a vertical or horizontal axis of symmetry, so a line of the form x=k or y=k is the easiest way

N45.00 by their grandfather. If Sola
received 40% of this amount, how
much remained to be shared between
Kemi and Ojo?
Answer:
N27.00 remained to be shared between Kemi and Ojo
Step-by-step explanation:
We have an amount of N 45.00.
Sola received 40% of this amount, which means that 100% - 40% = 60% remained to be shared between Kemi and Ojo.
This amount is given by:
0.6*45 = 27

Write a positive or negative integer that represents the situation.
You dive 10 feet below the surface of the water
An integer that represents the situation is [ ]?
Answer:
it's -10
Step-by-step explanation:
because in the question they says below the surface of the water
so I think it's right
The upward is taken as positive and the downward is taken as negative. Then the integer can be represented as negative 10.
What is a sign convention?Sign convention means the rule that is used when the sign is to be changed. It is applicable only when the equation is considered.
You dive 10 feet below the surface of the water.
Then the negative sign should be used because we considered the right side as positive and the left side as negative similarly upward is taken as positive and downward is taken as negative.
Then the integer can be represented as negative 10.

Usually Holly leaves home to school at 9:00, however today she left home 20 minutes later. In order to be at school on time she increased her usual speed by 20% and still was at school 15 minutes later than usual. What is her usual time from home to school
Answer:
Her usual time from home to school is 30 minutes
Step-by-step explanation:
At any point in time;
distance = speed * time
Here, we want to calculate the normal time she spent going from home to school
Let the normal time be x minutes
And the normal speed be t m/min
Today, she increased her speed by 20%
Her speed today will be t + 20/100 * t =
1.2t m/min
Her distance from how to school normally is
xt meters
Now what this means is that, at the increased speed, she was able to get to school 5 minutes earlier
What we are saying is although, she lost 20 minutes initially, she was able to beat down the lateness by 5 minutes
So, the time spent on her increased speed journey is;
(x-5) minutes
At any point in time, the distance will be equal;
Thus, mathematically;
xt = 1.2t(x-5)
xt = 1.2xt - 6t
6t = 1.2xt-xt
6t = 0.2xt
t cancels out
0.2x = 6
x = 6/0.2
x = 30 minutes

Answer:
The Area of the sector is: A = 95.4 cm²
Step-by-step explanation:
Given
Central angle Ф = 135°
radius r = 9 cm
To determine
Area of the sector = ?
The Area of the sector can be calculated using the formula
A = Ф/360 × πr²
substitute Ф = 135°, r = 9 and π = 3.14
A = 135/360 × (3.14) (9)²
A = 95.4 cm²
Therefore, the Area of the sector is: A = 95.4 cm²
