Answer:
Step-by-step explanation:
The angles GCJ and ACB are congruent.
So GCJ=ACB=63°.
And in Triangle ABC the sum of all angles is 180°.
Such an angle of BAC is calculated by:
The sum of all angles = ABC + BCA + CAB
180 = 90 + 63 + CAB
CAB = 27°
Then again angle KAI and CAB are congruent then
KAI = 27°

Which value from the set { -6, -4, -1, 0, 2, 4} satisfy the inequality?
−1/2x + 4 ≥ 6
Answers
Answer:
-4
Step-by-step explanation:
To find the value from the given set that satisfies the inequality, we can substitute each value into the inequality and see which one makes it true.
−1/2x + 4 ≥ 6
Subtracting 4 from both sides:
−1/2x ≥ 2
Multiplying both sides by -2 (and reversing the inequality):
x ≤ -4
Now we can check each value from the set and see which one satisfies the inequality:
-6 ≤ -4 (not true)
-4 ≤ -4 (true)
-1/2 ≤ -4 (not true)
0 ≤ -4 (not true)
2 ≤ -4 (not true)
4 ≤ -4 (not true)
Therefore, the only value that satisfies the inequality is -4.

Answer:
i belive its 22Step-by-step explanation:
V = 22To find the volume of 11 x 2, you need to know the third dimension, as volume is a three-dimensional measure. Assuming you mean the dimensions of a rectangular solid, you would need to know the height or depth of the object to calculate the volume. As for screen time for children, the American Academy of Pediatrics recommends limiting it to one hour per day for children aged 2-5 and to no more than two hours per day for children aged 6 and older. Engaging in creative play can help children develop important skills, such as problem-solving and communication, while excessive screen time has been linked to negative effects on cognitive and social development.
and 11 x 2 = 22.Answer:
The answer is 22
Step-by-step explanation:
You have to multiply the base times the height (2 x 11) Doing that will get you 22 ft.

Darla’s dinner at a restaurant cost $23.18 before tip. She wants to leave a 20% tip. What is the total cost of the dinner after Darla adds the tip?
Answers
Answer:
$27.816
Step-by-step explanation:
First we have to find out what 20% of 23.18 is. Let x represent the amount of the tip.
(cross multiply)
20 = x
100 23.18
20 x 23.18 = 463.6
463.6 ÷ 100 = 4.636
x = $4.636
Now we add the amount of the tip to the original price of the dinner.
23.18 + 4.636 = 27.816
Therefore the total cost of the dinner including the tip is $27.816

What is Proportional?Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
During the first year of operation, a company produced 8.4 x 10⁹ reams of paper.
And, During the second year, the company produced 5.6 times the number of reams of paper that it produced during the first year.
Hence, , In the first year, the company produced reams, and in the second year, 5.6 times that, that is, we multiply the amount by 5.6, hence:
⇒ 8.4 x 10⁹ x 5.6
⇒ 4.704 x 10¹⁰
Thus, Using proportions, it is found that the expression that represents the number of reams of paper the company produced during the second year is:

Use 3.14 for "pi" and round to the nearest hundredths place.
Answers
Answer:
28.26 square feet
Step-by-step explanation:
First, we can find the area of the rectangle in the shape. The area of a rectangle is the length*width. The length is 12ft, width is 3ft, 12*3 = 38sqFt.
Now for the circle (which is split in half). Area of a circle is pi*r^2.
The length of the whole bottom of the composite shape is 12. 6 of those feet are from the sides of the rectangle, which leaves 6 as the diameter of the circle. Radius is half of diameter, so it is 3.
pi*r^2 would give us 3.14*9 because the radius, which is 3, squared would give us 9. 9*3.14=28.26
Answer:

$3.48 chocolate pretzels
$8.26 almonds
$4.98 trail mix
Answers
Answer: $41.81 in total
Step-by-step explanation:
3.48 x 2.5 = 8.7
8.26 x 2.5 = 20.65
4.98 x 2.5 = 12.45
8.7 + 20.65 + 12.45 = $41.8
The cost of chocolate pretzels for 2.5 pounds is $8.7.
The cost of almonds for 2.5 pounds is $20.65
The cost of trail mix for 2.5 pounds is $12.45.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
We have,
$3.48 chocolate pretzels
$8.26 almonds
$4.98 trail mix
So, the cost of chocolate pretzels for 2.5 pounds
= 3.48 x 2.5
= $8.7
and, the cost of almonds for 2.5 pounds
= 8.26 x 2.5
= $20.65
and, the cost of trail mix for 2.5 pounds
= 4.98 x 2.5
= $ 12.45

2. If Mrs. Aguiar’s class has a five-number summary of 50, 60, 70, 80, and 95, which class’ scores are more consistent? How do you know?
3. The mean for Mrs. Tinney’s class is 85 and the mean for Mrs. Aguiar’s class is 70. What conjecture could we make about symmetry? Explain.
Answers
Answer:
1. Five-number summary for Mrs. Tinney's class scores:Minimum (Min): 60
First Quartile (Q1): 72
Median (Q2 or Median): 80
Third Quartile (Q3): 88
Maximum (Max): 100To draw the box and whisker plot, we can plot these
values on a number line:
| | | | |
60 72 80 88 95 100
We can then draw a box from Q1 to Q3, with a line inside representing the median (Q2), and draw whiskers from the box to Min and Max.
2. Mrs. Aguiar's class scores are more consistent compared to Mrs. Tinney's class scores. This can be determined from the interquartile range (IQR), which is the difference between the third quartile (Q3) and the first quartile (Q1) in a box and whisker plot. A smaller IQR indicates less variability in the data and hence more consistency. In this case, Mrs. Aguiar's class has an IQR of 80 - 60 = 20, while Mrs. Tinney's class has an IQR of 88 - 72 = 16. Therefore, Mrs. Aguiar's class scores are more consistent.
3. Based on the mean values, we can make a conjecture about symmetry. The mean is a measure of central tendency that represents the average of a set of data points. If the mean is close to the median, it suggests that the data is approximately symmetric. In this case, the mean for Mrs. Tinney's class is 85, which is closer to the median (Q2) of 80, indicating approximate symmetry. On the other hand, the mean for Mrs. Aguiar's class is 70, which is not close to the median of 80, suggesting that the data may not be symmetric. However, further analysis using other measures of skewness or visualization techniques may be needed for a more conclusive assessment of symmetry.

Answer:
Step-by-step explanation:
The quantities given are are in ounces for some and pounds for others
Convert everything to a common unit
1 pound = 16 ounces
Easier to convert all pounds to ounces since you will be working with whole numbers.
Solving by converting all pound units to ounces
1.5 pounds of turkey = 1.5 x 16 = 24 ounces of turkey
Total meat available for sandwiches
= 8 ounces of roast beef + 16 ounces of ham + 24 ounces of turkey
= 48 ounces
It takes 0.25 pounds of meat to make one sandwich
0.25 pounds = 0.25 x 16 = 4 ounces
Since it takes 4 ounces of meat to make a single sandwich and there are 48 ounces of meat available,
Total number of sandwiches = 48/4 = 12 sandwiches
What if we converted ounces to pounds and solved?
8 ounces = 8/16 pounds = 0.5 pounds
16 ounces = 1 pound
Total meat = 0.5 + 1 + 1.5 = 3 pounds
It takes 0.25 pounds of meat to make a sandwich
Therefore total number of sandwiches = 3/0.25 = 12 (same answer)

Mrs Dawson buys 3 yards of lace. Since there are 36 inches in a yard, she has 3 * 36 = 108 inches of lace.
She uses 30 inches of lace for the sleeves and 30 inches of lace around the waist, for a total of 30 + 30 = 60 inches of lace used.
Subtracting the amount of lace used from the total amount of lace gives 108 - 60 = 48 inches of lace left.
Since there are 12 inches in a foot, Mrs Dawson has 48 / 12 = **4** feet of lace left.

Assuming that the ball travels in a straight line from the release point to the corner pin, we can use the Pythagorean theorem to find the length of the bowling lane.
Let x be the length of the bowling lane in inches. Then we have:
x^2 = 40^2 + 720^2
x^2 = 1600 + 518400
x^2 = 520000
x = sqrt(520000)
x ≈ 721.1 inches
Rounding to the nearest tenth, the length of the bowling lane is approximately 721.1/12 = 60.1 feet.
Therefore, the length of the bowling lane is approximately 60.1 feet.
Answer:
The length of the bowling lane is 718.9 in

Step-by-step explanation:
The question is probably asking for the height of the triangle ( b ) so a is 40 in and c is 720 in : * use formula; c² - a² = b² *
720² - 40² = b²
518400 - 1600 = b²
516800 = b²
b = [tex]\sqrt{516800}[/tex]
b = 718.888030... in
