Which statements are true about the expression 8 (a + 7)? Check all that apply.
1.To simplify, distribute a to 8 and to 7.
2.8(a) can be rewritten as 8a.
3.8 (a + 7) can be rewritten as 8 (a) + 8 (7).
4.8 (a + 7) can be rewritten as 8 (a) + (7).
5.An equivalent expression is 15a.
6.An equivalent expression is 8 a + 7
7.An equivalent expression is 8 a + 56
Answer:
Option 3)
8(a + 7) can be rewritten as 8(a) + 8(7).
Option 7)
An equivalent expression is 8a + 56
Step-by-step explanation:
We are given the following expression:
[tex]8 (a + 7)[/tex]
We can simplify the expression by distributing 8 over (a+7).
Distributive property:
[tex]a(b+c)\\=(a\times b) + (a\times c)\\=a(b) + a(c)\\=ab + ac[/tex]
Simplifying the expression, we get,
[tex]8(a+7)\\=(8\times a)+(8\times 7)\\=8a + 56[/tex]
Thus, the correct options are:
Option 3)
8(a + 7) can be rewritten as 8(a) + 8(7).
Option 7)
An equivalent expression is 8a + 56
The true statements about the expression 8(a+7) are 2, 3 and 7.
When evaluating the expression 8(a+7), several steps can be taken to rewrite or simplify it. Here's a closer look at the provided statements:
Statement 1 suggests to distribute 'a' to 8 and to 7, which is incorrect. The correct procedure is to distribute the 8 to both 'a' and the 7.
Statement 2 correctly suggests that 8(a) can be rewritten as 8a.
Statement 3 is true, as 8(a+7) can be rewritten following the distributive property as 8(a)+8(7), which simplifies to 8a+56.
Statement 4 is incorrect because it omits the distribution of 8 over both terms within the parentheses.
Statement 5 is incorrect as there is no reason to believe that 8(a+7) simplifies to 15a without any additional information.
Statement 6 is incorrect as it implies that the 8 is only multiplied by 'a' and not by the 7.
Statement 7 is correct because the expression 8(a+7) is correctly expanded to 8a+56.

henry rolls 2 number cubes numbered 1 through 6 while playing his favorite board game. he will get a second turn if he rolls a sum that is an even number less than 10. what are henry’s chances of getting a second turn when he rolls the number cubes
Henry has 13 chances to get a second turn.
Step-by-step explanation:
When two number cubes numbered from 1 to 6 are rolled, the number of possible outcomes are 36.
The 36 possible outcomes are as follows :
(1,1), (1,2), (1,3), (1,4), (1,5), (1,6)
(2,1), (2,2), (2,3), (2,4), (2,5), (2,6)
(3,1), (3,2), (3,3), (3,4), (3,5), (3,6)
(4,1), (4,2), (4,3), (4,4), (4,5), (4,6)
(5,1), (5,2), (5,3), (5,4), (5,5), (5,6)
(6,1), (6,2), (6,3), (6,4), (6,5), (6,6).
It is given that, Henry gets the second turn if he rolls a sum that is an even number less than 10.
Therefore, the even numbers less than 10 are {2,4,6,8}.
Check for the sum of outcomes that gives the result of even number less than 10.
Sum of (1,1) (1,3) (1,5) gives 2,4,6 which are even numbers less than 10 ⇒ 3 chances.Sum of (2,2) (2,4) (2,6) gives 4,6,8 which are even numbers less than 10 ⇒ 3 chances.Sum of (3,3) (3,5) gives 6 and 8 which are even numbers less than 10 ⇒ 2 chances.Sum of (4,2) (4,4) gives 6 and 8 which are even numbers less than 10 ⇒ 2 chances.Sum of (5,1) (5,3) gives 6 and 8 which are even numbers less than 10 ⇒ 2 chances.Sum of (6,2) gives 8 which is a even number less than 10 ⇒ 1 chance.The total number of chances to get second turn = 3+3+2+2+2+1 = 13 chances.
Therefore, Henry has 13 chances to get a second turn.
The price of a pair of earrings is $22 but Priya buys them on sale for $13.20.
By how much was the price discounted?
What was the percentage of the discount?
Solution
Answer:
$8.8040%Step-by-step explanation:
The amount of the discount is the difference between the original price and the discounted price. That was ...
$22.00 -13.20 = $8.80
The percentage of the discount is the ratio of the amount of the discount to the original price. That was ...
8.80/22.00 × 100% = 40%
The price was discounted $8.80. That was a 40% discount.
Final answer:
The price of the earrings was discounted by $8.80 or 40%.
Explanation:
To find the amount by which the price was discounted, subtract the sale price ($13.20) from the original price ($22):
Discount = Original Price - Sale Price
Discount = $22 - $13.20 = $8.80
The percentage of the discount can be found by dividing the discount by the original price and multiplying by 100:
Percentage of Discount = (Discount / Original Price) * 100
Percentage of Discount = ($8.80 / $22) * 100 = 40%
Part A: A graph passes through the points (0.2). (1.3), and (2, 4). Does this graph represent a linear function or a non-linear function? Explain your answer in
words
Part 3: Write one example of a linear function and one example of a non-linear function (Use x and y as the variables)
Answer
a) Linear because there is a constant slope
b) Linear: y=x
Non-linear: y=1/x
Step-by-step explanation:
First we find the slope using the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]
For the points (0,2) and (1,3), we have
[tex]m = \frac{4-3}{1-0} = \frac{1}{1} = 1[/tex]
For the points (0,2) and (2,4), we have
[tex]m = \frac{4 - 2}{2 - 0} = \frac{2}{2} = 1[/tex]
For (1,3) (2,4), we have;
[tex]m = \frac{4 - 3}{2 - 1} = 1[/tex]
Since there is a constant rate of change the graph represents a linear function.
b) For a linear function, the highest degree is 1.
An example of a linear function is y=2x
For a non-linear function the degree of the variable is not equal to 1.
[tex]y = \frac{1}{x} [/tex]

Area of building is [tex]3,84,000m^3[/tex] .
Step-by-step explanation:
Here we have , a figure in given below picture where we have to find volume of this office building , Let's find out:
If we look closely we see that it's basically cuboid with dimensions 50 m by 110 m by 70 m . But there's one small cuboid sliced off from this cuboid with dimensions 50 m by 10 m by (110-90) m i.e. 50 m by 10 m by 20 m .
Area of building = Area of larger cuboid - Area of smaller cuboid
Area of cuboid = [tex]length(width)(breadth)[/tex]
⇒ Area of building = Area of larger cuboid - Area of smaller cuboid
⇒ [tex]Area = (50(110)(70))m^3 - (50(10)(20))m^3[/tex]
⇒ [tex]Area = 3,85,000m^3 - 10,000m^3[/tex]
⇒ [tex]Area = 3,84,000m^3[/tex]
Therefore, Area of building is [tex]3,84,000m^3[/tex] .

the area of a circle is 36/pi cm^2 What is the radius of the circle?
Answer:
the radius of the circle is 6cm
Step-by-step explanation:
the area of a circle is given to be = 36πcm²
radius of the circle = ?
to find the radius of the circle lets start by applying the formula for finding the area of a circle.
area of a circle = πr²
36πcm² = πr²
36π = πr²
divide both sides by π
36π/π = πr²/π
36 = r²
to get the value of r we are going to look for a way of getting rid of the square on "r" by squaring 36
r² = 36
r =√36
r = 6cm
therefore the radius of the circle is 6cm
Answer:
6 cm

Answer:
89.10
Step-by-step explanation:
To find the volume (how much soil can fit) you do Length x Width x Height in this case it is 4 x 9 x 3
4 x 9 x 3 = 108
Now you have to divide the volume by two because you only want to fill half the box.
108/2=54
Now you multiple the volume by the price to figure out how much soil will cost
54 x 1.65 = 89.1
It will cost $89.10
Heyo! I hope your day is going well! I hope I can help you understand this a bit better!
First things first we have to figure out the total volume of the flower box. To do this we do a simple multiplication problem, 3*4*9, or length*width*height. 3*4 is 12, and then 12*9 is 108. So our total volume for the flower box is 108 cubic feet.
Lucy only wants to fill half of her flower box, so we are going to go ahead and divide our total volume, 108 cubic feet, by 2. Our answer here is 54 cubic feet.
The soil Lucy wants to buy is 1.65 for each cubic foot, meaning we should multiply 1.65 and 54.Our final answer is 89.1!

The flag is 31.6 feet from the bottom of the sailboat.
Step-by-step explanation:
Step 1:
In the given triangle, the angle is 58°. Assume the opposite side has a length of x feet and the adjacent side has a length of 16 feet.
To determine the length of the opposite side of the triangle, we use the tan of the given angle.
[tex]tan \theta = \frac{oppositeside}{adjacent side} .[/tex]
Step 2:
In the given triangle,
The length of the opposite side = x feet,
The length of the adjacent side = 16 feet,
The angle of the triangle = 58°.
[tex]tan \theta = \frac{oppositeside}{adjacent side} , tan 58 = \frac{x}{16}, tan 58 = 1.6000.[/tex]
[tex]1.6 = \frac{x}{16} , x = (1.6)(16) = 25.6.[/tex]
Since Shianne's eyes are 6 feet from the bottom of the sailboat, the distance between the flag and the bottom of the sailboat [tex]= 25.6 + 6 = 31.6.[/tex]
So the flag is 31.6 feet from the bottom of the sailboat.

∠A and \angle B∠B are supplementary angles. If m\angle A=(3x+18)^{\circ}∠A=(3x+18)
∘
and m\angle B=(5x+2)^{\circ}∠B=(5x+2)
∘
, then find the measure of \angle A∠A.
Answer:
Angle A = 78
Step-by-step explanation:
Start with the equation 8x+20=180 and solve for x which equals x=20. You then substitute for x with the equation for angle A. A=3(20)+18 which makes angle A = 78
The measure of ∠A is 78 degrees.
What are supplementary angles?Two angels whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles.
Which means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.
∠A and ∠B are supplementary angles. If ∠A=(3x+18) and ∠B=(5x+2)
then find the measure of ∠A.
Now Start with the equation
8x+20 = 180
solve for x which equals x=20.
then substitute for x with the equation for angle A.
A=3(20)+18
angle A = 78
Hence, the measure of ∠A is 78 degrees.

in a right triangle, the 58cm hypotenuse makes a 51 angle with one of the legs. rounded to two decimals places, how long is that leg?
Answer:
36.50
To two decimal places
Step-by-step explanation:
The hypothenuse side in a right angle triangle has 58cm. While the angle touching one of its leg is 51°. How long is that leg.
From the right angled triangle, the size of the leg touching the hypothenuse is the adjacent side of the triangle, hence in trigonometry, the cosine rule is used, because it involves the adjacent and the hypotenuse.
Cos 51°=x/58
Let the size of the leg be x
Making x the subject
x=58(Cos51°)
x=36.500058
Correct to two decimal place
x=36.50
A psychology professor assigns letter grades on a test according to the following scheme.
A: Top 8% of scores
B: Scores below the top 8% and above the bottom 61%
C: Scores below the top 39% and above the bottom 16%
D: Scores below the top 84% and above the bottom 8%
F: Bottom 8% of scores
Scores on the test are normally distributed with a mean of 65.4 and a standard deviation of 9.7. Find the numerical limits for a D grade. Round your answers to the nearest whole number, if necessary.
The numerical limits for a D grade in psychology can be calculated using the Z-score formula. The cutoff scores are below the top 84% and above the bottom 8%. Using the mean of 65.4 and the standard deviation of 9.7, the numerical limits for a D grade are 52 to 79.
Explanation:To find the numerical limits for a D grade, we need to determine the cutoff scores. According to the given scheme, a D grade corresponds to scores below the top 84% and above the bottom 8%. To calculate these cutoff scores, we can use the Z-score formula. The Z-score is calculated as the difference between a score and the mean, divided by the standard deviation. Using the Z-score table, we can find the Z-scores corresponding to the top 8% and the bottom 8%. Finally, we can use the Z-score formula to find the corresponding scores for those Z-scores.
Given that the mean is 65.4 and the standard deviation is 9.7, we can calculate the Z-scores:
Z-score for the top 8% = 1.405
Z-score for the bottom 8% = -1.405
Using the Z-score formula, where X is the score, the mean is 65.4, and the standard deviation is 9.7:
X = Z * standard deviation + mean
For the top 8%:
X = 1.405 * 9.7 + 65.4 = 79
For the bottom 8%:
X = -1.405 * 9.7 + 65.4 = 52
Therefore, the numerical limits for a D grade are 52 to 79 (rounded to the nearest whole number).
