At a local toy store, extra-large stuffed bears had a price of $40 each.
In December, the price was raised by 30%. In January, the price was
lowered by50%. What is the price of an extra-large toy stuffed bear now?
Answer:
26
Step-by-step explanation:
40x30%=12
40+12=52
52x50%=26
At a local toy store, extra-large stuffed bears had a price of $40 each.
The price of an extra-large toy stuffed bear is $26.
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100.
At a local toy store, extra-large stuffed bears had a price of $40 each.
In December, the price was raised by 30%.
40 x 30%
= 1200/100
= 12
40 + 12 = 52
In January, the price was lowered by 50%.
52 x 50%
=2600/100
= 26
Thus, the price of an extra-large toy stuffed bear is $26.

9. The gradient of the curve y=kx⁴ at the point x = 2 is 128. Find the value of k.
Answer:
k = 4
Step-by-step explanation:
Here, we want to find the value of k
Mathematically, the gradient of a curve is same as the first derivative
so the first derivative here is;
dy/dx = 4kx^3
Now, the value of x here is 2 while the value of y is 128
Substituting these values;
128 = 4k(2)^3
128 = 32k
k = 128/32
k = 4

Given:
The angles are:
Example [tex]54^\circ[/tex]

2. [tex]87^\circ[/tex]
3. [tex]45^\circ[/tex]
4. [tex]72^\circ[/tex]
5. [tex]5^\circ[/tex]
To find:
The complimentary angle of the given angles.
Solution:
If two angles are complimentary, then their sum is 90 degrees.
Example: Let x be the complimentary angle of [tex]54^\circ[/tex], then
[tex]x+54^\circ=90^\circ[/tex]
[tex]x=90^\circ -54^\circ[/tex]
[tex]x=36^\circ[/tex]
Similarly,
1. The complimentary angle of [tex]63^\circ[/tex] is:
[tex]90^\circ -63^\circ=27^\circ[/tex]
2. The complimentary angle of [tex]87^\circ[/tex] is:
[tex]90^\circ -87^\circ=3^\circ[/tex]
3. The complimentary angle of [tex]45^\circ[/tex] is:
[tex]90^\circ -45^\circ=45^\circ[/tex]
4. The complimentary angle of [tex]72^\circ[/tex] is:
[tex]90^\circ -72^\circ=18^\circ[/tex]
5. The complimentary angle of [tex]5^\circ[/tex] is:
[tex]90^\circ -5^\circ=85^\circ[/tex]
Therefore, the complimentary angles of [tex]54^\circ, 63^\circ, 87^\circ, 45^\circ, 72^\circ, 5^\circ[/tex] are [tex]36^\circ, 27^\circ, 3^\circ, 45^\circ, 18^\circ, 85^\circ[/tex] respectively.

Find the 53rd term of the arithmetic sequence -12, -1, 10
440 is the answer
Tn=a+(n-1)d
Tn=53
a= -12
n=53
d= 11
-12+(53-1)11 = 440
Answer:
560Step-by-step explanation:
The sequence above is an arithmetic sequence
For an nth term in an arithmetic sequence
A(n) = a + ( n - 1)d
where a is the first term
n is the number of terms
d is the common difference
Since we're finding the 53rd term
a = - 12
n = 53
d = -1 - ( -12) = - 1 + 12 = 11 or 10--1 = 10 +1 =11
d = 11
So we have
A(53) = - 12 + (11)(53 - 1)
= - 12 + 11(52)
= -12 + 572
= 560
We have the final answer as

In PQR the measure of R=90, QR=61 feet and RP=90 find the measure of P to the nearest degree.
Answer:
<P = 56 degrees
Step-by-step explanation:
Given the following
m<R = 90 degrees
QR = 61feet = Adjacent
RP = 90 feet= Opposite
Required
tan<P = opp/adj
Tan<P = 90/61
<P = arc tan (90/61)
<P = arctan 1.4754
<P = 55.9
<P = 56 degrees to the nearest degree

the cost of a customer smartphone bill can be modeled by the equation c=10g+50
Answer:
c=10(g+5)
Step-by-step explanation:
Given that,
The cost of customer smartphone bill is given by the equation as follows :
c=10g+50
Where
g is the number of gigabits of data the customer per month
We need to factor this cost polynomial
The common between 10 and 50 is 10
Taking 10 common. So,
c=10(g+5)
Hence, the required factor is equal to c=10(g+5).
Subtracting fractions with unlike denominators
Answer:
[tex]\frac{9}{4} - \frac{5}{10} = 1\frac{3}{4}[/tex]
Step-by-step explanation:
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
LCD(9/4, 5/10) = 20
[tex](\frac{9}{4} * \frac{5}{5} ) - (\frac{5}{10} * \frac{2}{2} ) = ?[/tex]
Complete the multiplication and the equation becomes
[tex]\frac{45}{20} - \frac{10}{20}[/tex]
The two fractions now have like denominators so you can subtract the numerators.
Then:
[tex]\frac{45 - 10}{20} = \frac{35}{20}[/tex]
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 35 and 20 using
GCF(35,20) = 5
[tex]\frac{35 / 5 }{20 / 5} = \frac{7}{4}[/tex]
The fraction
[tex]\frac{7}{4}[/tex]
is the same as
7 ÷ 4
Therefore:
[tex]\frac{9}{4} - \frac{5}{10} = 1\frac{3}{4}[/tex]
Apply the fractions formula for subtraction, to
[tex]\frac{9}{4} - \frac{5}{10}[/tex]
and solve
[tex]\frac{(9 * 10)- (5* 4) }{4 * 10}[/tex]
[tex]= \frac{90-20}{40}[/tex]
[tex]= \frac{70}{40}[/tex]
Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(70,40) = 10
[tex]\frac{70/ 10 }{40 / 10} = \frac{7}{4}[/tex]
Convert to a mixed number using
long division for 7 ÷ 4 = 1R3, so
[tex]\frac{7}{4} = 1\frac{3}{4}[/tex]
Therefore:
[tex]\frac{9}{4} - \frac{5}{10} = 1\frac{3}{4}[/tex]
What is the selling price per widget as a function of the
number of widgets produced, and what should the
selling price be if 15 widgets are produced?
Answer:
1240 widgets
Step-by-step explanation:
The value of the function at 870, the local maximum, is
= -0.02(870)2 + 34.80(870) - 4700
= -0.02(756900) + 30276 - 4700
= -15138 + 25576
= 10438
So the vertex is (870, 10438)
The cost t the company to produce 870 widgets is
C(870) = 4700 + 5.20(870) = 4700 + 4524 = 9224
So, the cost of the widgets plus the profit must be equal to the total sales, which is divided by the number of widgets reveal their individual price.
(10438 + 9224)/870 = 19662/870 = $22.60
P(x) = 7700
- 0.02x2 + 34.80x - 4700 = 7700
-0.02x2 + 34.80x -12400 = 0
x = {-34.80 ± √[(34.80)2 - 4(-0.02)(-12400)]}/2(-0.02)
x = [-34.80 ± √(1211.04 - 992)]/(-0.04)
x = (-34.80 ± √219.04)/(-0.04)
x = (-34.80 ± 14.8)/(-0.04)
x = 870 ± 370
so, $7700 in profits will be earned at either 500 widgets or 1240 widgets

A farmer sells 8.1 kilograms of apples and pears at the farmer's market. 2 5 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?
The question is incomplete:
A farmer sells 8.1 kilograms of apples and pears at the farmer's market. 2/5 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?
Answer:
She sold 4.86 kg of pears at the farmer's market.
Step-by-step explanation:
With information provided, you know the amount of kilograms of apples and pears sold and that 2/5 of this weight is apples, so you can find first the number of kilograms of apples sold by multipying 2/5 for 8.1 kilograms:
2/5*8.1=3.24 kg
Now, you can find the kilograms of pears that the farmer sold by subtracting the kilograms of apples sold from the total amount of apples and pears sold:
8.1-3.24=4.86 kg
According to this, the answer is that she sold 4.86 kg of pears at the farmer's market.
