Answer:
C. (5x + 6) (5x - 6)
Step-by-step explanation:
25 is a perfect square, meaning its two factors are identical (5), and 36 is also a perfect square with two identical factors (6). With this information, we can split the expression below like this:
[tex]25x^2 - 36\\(5x ) (5x )[/tex]
Since 36 is negative, we have to have a positive 6 and a negative 6:
(5x - 6) (5x + 6)

Sandy does babysitting in her spare time. She gets $100 advance pay and $10 per hour for babysitting. She wants to earn enough to buy a new Iphone for $450. How many hours she needs to babysit to earn enough money to buy the Iphone?
Answer: 35 hours
Step-by-step explanation: 450-100 because of the advanced pay, then you dived 350 by ten so you get 35 hours
Answer:
Sandy needs to babysit for 35 hours to earn enough money to buy an Iphone.
Explanation:
Sandy gets $100 advance pay and $10 per hour for babysitting.
Let x denotes the number of hours then
10x + 100
Sandy wants to buy an Iphone for $450
10x + 100 = 450
Solving the above equation
10x = 450 - 100
10x = 350
x = 350/10
x = 35 hours
Therefore, Sandy needs to babysit for 35 hours to earn enough money to buy an Iphone.

There are 14math teachers and 26 science teachers at school today. What is the ratio of math teachers to math and science teachers at school?
It's basically asking "what is the ratio of math teachers to total teachers?" assuming there are only math and science teachers at this school. For the sake of simplicity, let's just go with that. We have 14 math teachers and 14+26 = 40 teachers total. The ratio of math to total is 14:40 which reduces to 7:20 when we divide both parts of the ratio by the GCF 2.
Answer: 7: 13
The ratio would be 14: 26, however you are most likely asked to simplify it. Which is why the answer would be 7: 13

Answer:
y+3x+11=0
Step-by-step explanation:
m=-3, x1=-4, y1=1
from m=y-y1/x-x1
-3=y-1/x-(-4)
-3(x+4)=y-1
-3x-12+1=y
y=-3x-11
y+3x+11=0

Answer:
1/3(0.3333333333%)

joe paid 14.00 for a broard game. THis is 70% of the orginal price. What was the orginal price?
Answer:
20.00
Step-by-step explanation:
14 is 70% of X
70/100 × X = 14
X = 14 × 100/70
X = 20.00
Owners of a minor league baseball team believe that a Normal model is useful in projecting the number of fans who will attend home games. They use a mean of 8500 fans and a standard deviation of 1500 fans. Using this model, answer these questions. a. Sketch and clearly label this Normal model, based on the 68-95-99.7 Rule. b. What proportion of the home games will have fewer than 6000 fans in attendance
Answer:
a) [tex] \mu -\sigma = 8500 -1500 = 7000[/tex]
[tex] \mu +\sigma = 8500 +1500 =10000[/tex]
[tex] \mu -2*\sigma = 8500 -2*1500 = 5500[/tex]
[tex] \mu +2*\sigma = 8500 +2*1500 =11500[/tex]
[tex] \mu -3*\sigma = 8500 -3*1500 = 4000[/tex]
[tex] \mu +3*\sigma = 8500 +3*1500 =13000[/tex]
On the figure attached we have the illustration for required showing the percentages and the limits for each case
b) [tex] z= \frac{6000-8500}{1500}= -1.67[/tex]
And using the normal standard table or excel we got:
[tex] P(Z<-1.67) = 0.047[/tex]
Step-by-step explanation:
For this case we have the following properties:
[tex] \mu = 8500, \sigma = 1500[/tex]
Part a
And for this case from the empirical rule we know that within one deviation from the mean we have 68% of the values , within two deviation 95% and within 3 deviations 99.7%. So then we can find the limits like this:
[tex] \mu -\sigma = 8500 -1500 = 7000[/tex]
[tex] \mu +\sigma = 8500 +1500 =10000[/tex]
[tex] \mu -2*\sigma = 8500 -2*1500 = 5500[/tex]
[tex] \mu +2*\sigma = 8500 +2*1500 =11500[/tex]
[tex] \mu -3*\sigma = 8500 -3*1500 = 4000[/tex]
[tex] \mu +3*\sigma = 8500 +3*1500 =13000[/tex]
On the figure attached we have the illustration for required showing the percentages and the limits for each case
Part b
For this case we want to find this probability:
[tex] P(X<6000)[/tex]
We can calculate the number of deviation below the mean with the z score formula given by:
[tex] z = \frac{X -\mu}{\sigma}[/tex]
And replacing we got:
[tex] z= \frac{6000-8500}{1500}= -1.67[/tex]
And using the normal standard table or excel we got:
[tex] P(Z<-1.67) = 0.047[/tex]

Answer:
good news, the second one is relatively easy because it can be factored to (2x+1)(2x-3) which means that number two has solutions of -1/2 and 3/2
but for number one you have to either use the quadratic equation cause I've tried using synthetic division or just use the second equation to derive the first solutions so I tried move the graph up by two units and found that the intercepts are approximately (1+-√2)/2 or 1/2+-1/√2 for 4x^2-4x-1

Answer: 49
Step-by-step explanation:
[tex]-11\frac{2}{3}*-4\frac{1}{5}[/tex]
The first thing we are going to do is to convert to an improper fraction. To do this, you take the whole number, you multiply it by the denominator and add the numerator; all over the same denominator.
[tex]-\frac{11*3+2}{3}*-\frac{4*5+1}{5}[/tex]
Solve;
[tex]-\frac{33+2}{3}*-\frac{20+1}{5}[/tex]
[tex]-\frac{35}{3}*-\frac{21}{5}[/tex]
Now you can simply multiply numerators and denominators. Also, remember the negative signs which become positive because -*-=+
Before multiplying, it's easier to solve fractions that are being multiplied if you simplify them.

The typical amount of sleep per night that adults get has a bell-shaped distribution with a mean of 7.5 hours and a standard deviation of 1.3 hours. About 68% of adults typically sleep between a minimum of ___ hours a night and a maximum of ____ hours a night. Please enter your answer in the following format and round to the first decimal place: (min_value, max_value)
Answer:
(6.2, 8.8).
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed(bell-shaped) random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 7.5 hours
Standard deviation = 1.3 hours
About 68% ...
By the Empirical Rule, within 1 standard deviation of the mean.
7.5 - 1.3 = 6.2
7.5 + 1.3 = 8.8
So in the format requested
(6.2, 8.8).
The Cortes’ have a monthly combined take-home pay of $3,750. The Cortes’ recorded the following housing expenses for the month of August: $878.65 for mortgage payment; $52.50 for insurance premium; $266.67 for real estate taxes; $94.52 for electricity; $45.03 for telephone service; and $42.65 for water. How much are their housing costs over or under the FHA guidelines?
1 point
$67.52 under
$67.52 over
$2,369.98 under
$2,369.98 over
Answer:
I can't say over or under because I don't know the FHA guidelines but they had $2369.98 left over after the housing costs ($1380.02)
Step-by-step explanation:
Expenses for August= 878.65 + 52.50 + 266.67 + 94.52 + 45.03 + 42.65
= $1380.02
Income-Expenses= 3750-1380.02= 2369.98
Micah is filling up his cone-shaped cup with water. The cup (as shown) has a diameter of 72 millimeters and a slant height of 45 millimeters. How much water can Micah fill in his cup?
Answer:
Micah can put 61072.56 ml³ of water in his cup.
Step-by-step explanation:
The volume of a cone is given by the following formula:
[tex]V = \frac{h\pi r^{2}}{3}[/tex]
In which h is the height and r is the radius.
The radius is half the diameter.
In this question:
Radius of 72/2 = 36 ml. So [tex]r = 36[/tex]
Height of 45 ml, so [tex]h = 45[/tex]
The dimensions are in ml, so the volume will be in ml³.
So
[tex]V = \frac{h\pi r^{2}}{3}[/tex]
[tex]V = \frac{45\pi*(36)^{2}}{3}[/tex]
[tex]V = 61072.56[/tex]
Micah can put 61072.56 ml³ of water in his cup.

The ratio of sailboats to dinghies in the bay was 5 to 7 If there were 70
sailboats in the bay, how many dinghies were there?
Answer:
98
Step-by-step explanation:
Let the sailboats be s and the dinghies be d.
We have that:
s : d = 5 : 7
In other words:
s / d = 5 / 7
If there are 70 sailboats, this implies that s = 70
=> 70 / d = 5 / 7
=> d = (70 * 7) / 5 = 490 / 5 = 98
There will be 98 dinghies.
