Answer:
(-4,-3)
Step-by-step explanation:
The first coordinate of the ordered pair is the x value or go across
to the right is positive and the left is negative so x = -4
The second coordinate of the ordered pair is the y value or go up and down
up is positive and down is negative so y = -3
(-4,-3)
Answer:
(-4, -3)
Step-by-step explanation:
You can move 4 left from the x axis to get -4, and then move 3 down from the y axis to get -3, leading to the coordinates (-4, -3).
Camillo used the calculations shown to determine how much he would spend on 2,400 oz of jelly. 48 ounces of jelly costs 3 collars and 84 cents. (StartFraction 48 ounces Over 3 dollars and 84 cents EndFraction) (StartFraction question mark ounces Over 1 dollar EndFraction). Unit price = 13 dollars and 79 cents. 13 dollars and 79 cents (2,400) = 33 thousand and 96 dollars. What is his error? He placed the decimal point incorrectly when dividing. He placed the decimal point incorrectly when multiplying. He wrote the rate incorrectly. He did not make an error.
Answer:
He wrote the rate incorrectly
Step-by-step explanation:
Camille's calculation
(48/$3.84)(?/s1)
48x/3.84
=$13.79
The correct calculation
(48/$3.84)(?/s1)
48x/3.84
=$12.50
To find the error in Camille's calculation
(48/$3.84)(?/s1)
48x/3.84
=$13.79
We will divide 48 ounces of jelly by $13.79 to get the rate
48/13.79
=$3.48
Therefore, Camille wrote the rate incorrectly by interchanging .84 after the decimal for .48

out of 40 coins, 16 are dimes. half of the remaining coins are quarters and the rest are pennies and nickles. these are 2 nickles for every penny. how many pennies are there?
===========================================
Work Shown:
40 coins total
16 are dimes
40-16 = 24 coins are not dimes
Half of this is 24*(1/2) = 12 which are quarters. The other half (12) are pennies and nickels
n = number of nickels
p = number of pennies
This means n+p = 12 so that we have 12 pennies and nickels combined.
"There are 2 nickels for every penny", so we can write n = 2p. If p = 1, then n = 2. If p = 2, then n = 4, etc. Whatever p is, we double it to get n.
So,
n+p = 12
2p+p = 12
3p = 12
p = 12/3
p = 4, we have 4 pennies
n = 2p
n = 2*4
n = 8 and 8 nickels
-----------------------------------------
Here are all the coin counts
16 dimes12 quarters8 nickels4 pennies16+12+8+4 = 40 coins total
Answer:
Option (B) is correct, 4 pennies.

What is the measure of XZ (the minor arc)?
A. 116
B. 290
C. 244
D. 58
Answer:
D
Step-by-step explanation:
The required measure of XZ (the minor arc) is 116. Option A is correct.
In the figure, a circle gave with 3 arc divisions XY, YZ, and XZ. And angle 58 at point y.
The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by. (x-h)²+(y-k)²=2 where h, k is the coordinate of the circle's center on the coordinate plane and r is the circle's radius.
Since by the property of the circle the angle subtended by arc to the vertex corresponding to the center is half the measure of the angle subtended by the arc to the center.
so, let the center of the circle is o.
Now,
measure of XZ = 2 * 58
= 116
Thus, the required measure of XZ (the minor arc) is 116.

Gary ordered 30 pizzas for a party. 60% of the pizzas have 12 slices each. The remaining 40% of the pizzas have 10 slices each. Complete the model. Then complete the statements to find the total number of slices of pizza
Statement #1:
Since there are 30 total pizzas then the amount of pizzas with 12 slices is 60% of 30 which is 18. Then you can multiply 18 by 12 to get the amount of slices in the large pizzas with 12 slices:
18 × 12 = 216
-----------------------------------------------------------------------------------------------------------------
60% of the pizzas have 12 slices each. In total, there are 216 slices in these pizzas.
Statement #2
There are 12 remaining pizzas which means that 12 × 10 = 120 is the amount of slices in total of the smaller pizzas.
-----------------------------------------------------------------------------------------------------------------
40% of the pizzas have 10 slices each. In total, there are 120 slices in these pizzas.
Statement #3
To get the total amount of pizzas you simply add both of the previous solutions:
216 + 120 = 336
-----------------------------------------------------------------------------------------------
Altogether, there is a total of 336 slices of pizza.

Which statement is true about the polynomial 5s6t2 + 6st9 – 8s6t2 – 6t7 after it has been fully simplified? It has 3 terms and a degree of 9. It has 3 terms and a degree of 10. It has 4 terms and a degree of 9. It has 4 terms and a degree of 10.
Answer: The polynomial has 3 terms and a degree of 10.
Step-by-step explanation:
The given polynomial: [tex]5s^6t^2 + 6st^9 - 8s^6t^2 - 6t^7[/tex]
Here, two terms [tex]5s^6t^2[/tex] and [tex]8s^6t^2[/tex] have same power for s and t i.e. they are like terms.
Combine like terms , we get
[tex]6st^9 - 3s^6t^2 - 6t^7.[/tex] i.e. there are 3 terms.
Degree of [tex]6st^9[/tex] is 1+9=10;
Degree of [tex]- 3s^6t^2[/tex] is 6+2=8;
Degree of [tex]- 6t^7[/tex] is 7.
Since degree of the polynomial = highest degree i.e. 10
Hence, the polynomial has 3 terms and a degree of 10.
The statement which is true about the polynomial 5s⁶t² + 6st⁹ – 8s⁶t² – 6t⁷ is; It has 4 terms and a degree of 10.
Discussion:
By counting the number of terms in the polynomial;
We can conclude that the polynomial has 4 terms and hence can be called a tetranomial.Additionally, the degree of the polynomial is 10.
This is from the term with the highest degree which is; 6st⁹; where s has degree 1 and t has degree 9; total of which is; 10.

Calculate the future value of $51,123.21
Answer:
Option a) $ 82,531.59
Step-by-step explanation:
The Formula for Future value =
Present value (1 + r/n)^nt
From the question
Present value = $51,123.21
Interest rate (r) = 2 3/8 % = 2.375% = 0.02375
n = compounding frequency = compounded daily = using the traditional bankers rule of 30 days = 30 × 12 months = 360
T = Time duration in years = 20 years and 2 months = 20.1667
Future value = $ 51,123.21(1 + 0.02375/260)^20.1667 × 360
Future value = $ 82,531.59
A certain forest covers an area of 1900km^2. Suppose that each year this area decreases by 7.75%. What will the area be after 14 years?
Answer:
Assume that 1900km^2 is 1900.
If that happens, The equation of that will look like...
1900 - (1900 x 7.75% x 14)%.
1900 x 7.75% are 147.25.
and 147.25 x 14 are 2061.5.
so... there will be no forest after 14 years.(harsh)
Hope it helps!
The area of the forest after 14 years would be 614.1617 km².
We have,
Let's denote the initial area of the forest as A₀ = 1900 km².
The decrease in the area each year is 7.75%, which means that the remaining area after each year is 92.25% of the previous year's area.
i.e
[tex]A_i= A_0[/tex] (1 - 0.0775)
where Aᵢ is the area after i years.
To find the area after 14 years.
A₁₄ = 1900 x [tex](1 - 0.0775)^{14}[/tex]
= 1900 x 0.3232430884671
= 614.1617 km²
Therefore,
The area of the forest after 14 years would be 614.1617 km².

PLEASE HELP!!!! Emily is making 2 gallons of punch with 4 parts grape juice to 3 parts pineapple juice to 1 part sparkling cider. How many cups of pineapple juice will Emily need?? Hint (1 gallon = 16 cups)
1 gallon = 16 cups. She is making 2 gallons so needs 32 total cups.
The ratio is 4:3:1
Add the ratios: 4+ 3 + 1 = 8
Divide total cups by total ratio:
32/8 =4
Now multiply that by each portion of the ratio:
Grape juice = 4 x 4 = 16 cups
Pineapple juice = 3x4 = 12 cups
Cider = 1x 4 = 4 cups
She needs 12 cups of pineapple juice.

Does coordinate c or coordinate d represent a greater number?
Answer:
Coordinate d
Step-by-step explanation:
Answer: d is larger
c = -2 and d = -1
====================================================
Explanation:
We have c = -2 as this is the same as the x coordinate of (-2,-1), which is the point directly below (c,5).
The point (3,d) is on the same horizontal level as (-2,-1), so the y coordinates must match up. We therefore have d = -1.
Comparing c = -2 and d = -1, we see that d = -1 is larger as it is to the right of -2.
