Answer:
OPTION A
OPTION B
OPTION D
Step-by-step explanation:
Given that a bag of apples cost 'a' dollars.
A bag of oranges cost 'a + 2' dollars.
Therefore, one bag each of apples and oranges should cost: a + a + 2 dollars.
Since, Dorie buys 5 bags of apples and Oranges, it would have costed her:
5(a + a + 2)
= 5(2a + 2)
= 10a + 10
Hence, OPTION A, B and D are the correct answers.
HELP QUICK I NEED TO KNOW THIS Kiva’s family is moving and he helps by carrying a 21-pound box to the truck. It is 65% lighter than the box that his father carries to the truck. What is the weight of the box that Kiva's father carries?
To determine the weight of the box Kiva's father carries, we calculate 21 pounds as 35% of the father's box weight and find it to be 60 pounds.
Explanation:Kiva's family is moving and he carries a 21-pound box which is 65% lighter than the box his father carries. To find the weight of the box that Kiva's father carries, we need to determine what weight would be 65% lighter by the smaller box's weight. Let's denote the father's box weight as F. We know that 21 pounds is equal to 35% of the father's box's weight because 100% - 65% = 35%. So, we have:
Represent the relationship as an equation: 0.35F = 21.Divide both sides of the equation by 0.35 to find F: F = 21 ÷ 0.35.Calculate F to find the father's box weight: F = 60 pounds.Therefore, the weight of the box that Kiva's father carries is 60 pounds.

JKL is a right triangle. JL = 10, KL = 8,
and JK = 6. What is cos L?
10
What is the answer
Answer:
[tex] \cos L = \dfrac{4}{5} [/tex]
Step-by-step explanation:
The right angle is angle K. KL and JK are legs. JL is the hypotenuse.
For angle L, KL is the adjacent leg.
In general, for acute angle A of a right triangle,
[tex] \cos A = \dfrac{adjacent~leg}{hypotenuse} [/tex]
In this case,
[tex] \cos L = \dfrac{adj~leg}{hyp} [/tex]
[tex] \cos L = \dfrac{KL}{JL} [/tex]
[tex] \cos L = \dfrac{8}{10} [/tex]
[tex] \cos L = \dfrac{4}{5} [/tex]

Andy flies from the UK to Japan.
His plane ticket costs £554.
Andy then flies from Japan to Australia.
His plane ticket costs 70 140 Japanese Yen.
The exchange rate is £1 = 140 Japanese Yen.
Leila flies from the UK to Australia.
Her plane ticket costs 1860 Australian dollars.
The exchange rate is 1 Australian dollar = £0.62.
Who pays more to fly from the UK to Australia, Andy or Leila?
You must show clearly how you get your answer.
Answer: Leia pays more to fly from the UK to Australia
Step-by-step explanation:
We have two persons, Andy and Leila; both travel from UK to Australia but in different ways:
For Andy:
-He first flies from UK to Japan and the cost of the ticket is [tex]\£ 554[/tex]
-Then he flies from Japan to Australia and the cost of the ticket is [tex]70140 Yen[/tex]
So, the cost of Andy's trip is:
[tex]\£ 554+70140 Yen[/tex] (1)
Taking into account that we have to use the same units to sum two quantities, we have to convert the Yens to [tex]\£[/tex]; knowing that [tex]\£ 1=140 Yen[/tex]:
[tex]70140 Yen \frac{\£ 1}{140 Yen}=\£501[/tex]
Then, (1) is rewritten as:
[tex]\£ 554+\£501=\£1055[/tex] (2) This is the total cost of Andy's trip
For Leila:
She flies directly from UK to Australia and the cost of her ticket is [tex]\$ 1860[/tex] (Australian dollars)
Taking into account that we have the price of Andy's trip in [tex]\£[/tex], we have to convert the Australian dollars to [tex]\£[/tex], in order to compare.
So, knowing that [tex]\$ 1=\£ 0.62[/tex] we have:
[tex]\$ 1860 \frac{\£ 0.62}{\$ 1}=\£1153.2[/tex] (3) This is the total cost of Leila's trip
Hence, comparing (2) and (3) we can see that Leila paid more to fly from UK to Australia.
Choose all that give the correct expression for the quantity described.

a pool manager balances the ph level of a pool. the price of a bucket of chlorine tablets is $90, and the price of a ph test kit is $11. the manager uses a coupon that applies a 40% discount to the total cost of the two items. how much money does the pool manager pay for each item?
The pool manager pays $54 for the chlorine tablets and $6.60 for the pH test kit.
Explanation:The pool manager pays $54 for the bucket of chlorine tablets and $6.60 for the pH test kit after applying the 40% discount.
To find the price of the chlorine tablets after the discount, we multiply $90 by 40% to get $36. Subtracting $36 from $90 gives us the final price of $54.To find the price of the pH test kit after the discount, we multiply $11 by 40% to get $4.40. Subtracting $4.40 from $11 gives us the final price of $6.60.Therefore, the pool manager pays $54 for the chlorine tablets and $6.60 for the pH test kit.

The pool manager pays the cost of $54 for the chlorine tablets and $6.60 for the pH test kit.
Explanation:The calculation you're looking to perform is a simple example of a percentage discount on a sum of money. To figure out how much the pool manager pays for each item, you have to first calculate the total cost of the items. The total cost of both the bucket of chlorine tablets ($90) and the pH test kit ($11) is $101.
A 40% discount on the total cost is then calculated by taking 40% of $101, which is $40.40. This discount is subtracted from the total cost (101-40.40), leaving the pool manager to pay $60.60. To determine the cost of each item after the discount, we assume that the discount was applied equally to both items.
This means that the cost price for each the bucket of chlorine tablets and pH test kit, after the discount, would be $54 and $6.60 respectively.

Answer:
E) (-4, -3)
Step-by-step explanation:
To use elimination, you need to have one variable in both equations that have the same coefficient. (The coefficient is the number attached to the variable). Both equations have "7y".
The way elimination works is by eliminating one of the variables first. Decide how (-7y) and (-7y) can cancel out and become 0. You can either add or subtract.
(-7y) - (-7y) Try subtracting
= (-7y) + 7y
= 0
Based on this, we should subtract the whole equations.
Set up the equations like normal subtraction. Then, subtract each of the terms that have the same variable.
. 4x - 7y = 5
- 9x - 7y = -15 Do 4x - 9x = -5x. -7y - (-7y) = 0. 5 - (-15) = 20.
. -5x - 0 = 20 "y" cancelled out
. -5x = 20 Isolate 'x'
. -5x/-5 = 20/-5 Divide both sides by -5
. x = -4 Solved x-coordinate
Substitute 'x' for -4 in any of the equations. Then simplify and isolate "y" to solve for the y-coordinate.
4x - 7y = 5
4(-4) - 7y = 5 Simplify the multiplication.
-16 - 7y = 5 Start isolating 'y' now
-16 + 16 - 7y = 5 + 16 Add 16 to both sides. Left side cancels out 16
-7y = 5 + 16 Solved right side by adding
-7y = 21
-7y/-7 = 21/-7 Divide both sides by -7
y = -3 Solved y-coordinate
Therefore the answer is (-4, -3).

In circle D, mGEC is 230º. What is the measure of ∠GDC ? 70º 130º 170º 360º A circle with center D has points G, F, C and E on the circumference. Points G and D are connected by a line segment. Points D and C are connected by a line segment. Point F is between points G and C and point E is to the left of point G.
The answer is 130. I did the quiz and got it right.
I really hope this ends up helping you. You got this!
The measure of ∠GDC is 130° as it is calculated by subtracting the arc GEC's measure from the total degrees in a circle, which is 360°.
If the measure of arc GEC in circle D is 230°, to find the measure of ∠GDC,
we recall that the measure of an arc in a circle is equal to the measure of the central angle that intercepts that arc. Since ∠GDC is a central angle intercepting arc GEC, its measure must also be 230°.
However, because we are looking for the measure of the angle inside the circle, we must subtract this angle from the total 360° of the circle.
So,
360° - 230°
= 130°
So, the measure of ∠GDC is 130°.
A regular hexagon is shown.
What is the measure of the radius, c, rounded to the nearest inch? Use the appropriate trigonometric ratio to solve.
6 in.
10 in.
14 in.
24 in.
Answer:
14 in.
Step-by-step explanation:
well to start we have to know the relationships between angles, legs and the hypotenuse.
a: adjacent
o: opposite
h: hypotenuse
sin α = o/h
cos α= a/h
tan α = o/a
now as we know that the triangle that is formed has a right angle of 90 degrees, and two other angles that are 30 and 60 degrees.
We can know this by the properties of the hexagons
hexagon is formed by 6 equilateral triangles
equilateral triangles have 3 angles of 60 degrees
the triangle of the image is half of one of those triangles so it will have the upper angle of 30 and the other of 60
Now if we take the angle of 30 degrees and apply the following formula
sin α = o/h
cos 30 = a/h
0.866 = 12/h
h = 12/0.866
h = 13.8564
h = c
the nearest number is 14

express 0.003597 to three significant figures
Answer:
0.00360.
Step-by-step explanation:
Leading zeros in a number are not significant, so your number has four significant figures.
You must drop the 7 from 0.003597.
Since 7 is greater than 5, you must add 1 to the 9
[tex]\begin{array}{r|l}1& \\0.00359 &\text{7}\!\!\!\!\diagup \\\mathbf{0.00360} & \\\end{array}[/tex]
Final answer:
To express 0.003597 to three significant figures, round to 0.00360; in exponential notation, this is 3.60 × 10^-3.
Explanation:
To express 0.003597 to three significant figures, we identify the first non-zero digit as the starting point of significant figures.
We count three digits from there, which gives us 0.00360 when rounding up the seventh which is in the fourth place after the decimal. In exponential notation, this would be 3.60 × 10-3.
The two figures above are congruent. Find the measure of the angle that isn't labeled on either figure.

Jack has some marbles. He has ten more red marbles than blue marbles. He has fewer yellow marbles than blue marbles.
How many of each color marble could Jack have?
(This is the whole question)
A possible number of marbles for this situation is:
Red = 13
Blue = 3
Yellow = 2
How many of each color marble could Jack have?
Let's define the variables:
R = number of red marbles.
B = number of blue marbles.
Y = yellow marbles.
Then we can write:
R = B + 10
Y < B
So we have only these two conditions, now let's find possible values.
If we define B = 3, then:
R = 3 + 10 = 13
Y < 3
Then Y can be 2.
So a possible value is:
Red = 13
Blue = 3
Yellow = 2
Final answer:
The number of each color marble Jack has can be determined by setting the number of blue marbles as a variable. Red marbles are ten more than blue, and yellow marbles are fewer than blue. Specific combinations are possible as long as these conditions are met.
Explanation:
Jack has some marbles. He has ten more red marbles than blue marbles and fewer yellow marbles than blue marbles. To determine how many of each color marble Jack could have, consider blue marbles as the variable x. Then, the number of red marbles would be x + 10 and the number of yellow marbles would be less than x.
Here are a few possible combinations:
If Jack has 1 blue marble, he cannot have 10 more red marbles and fewer yellow marbles as this would result in a negative number of yellow marbles which is not possible.
If Jack has 2 blue marbles, then he would have 12 red marbles (x + 10), and potentially 1 yellow marble since it needs to be less than the number of blue marbles.
If Jack has 3 blue marbles, he would have 13 red marbles, and it could be 1 or 2 yellow marbles.
Thus, the compositions of marbles are dependent on the number of blue marbles Jack has. As long as the number of red marbles is ten more than blue and the yellow marbles are fewer than blue, the condition is satisfied.
