No
Step-by-step explanation:
3² + 1 = 7? Nopeeeee
3 * 3 = 9, that alone is bigger than 7.
3 * 3 + 1 = 10.
10 is bigger than 7.
Answer:
No
Step-by-step explanation:
To know if (3, 7) is a solution, plug 3 into the x and 7 into the y.
[tex](3)^{2} +1=7[/tex]
9 + 1 = 7
[tex]10\neq 7[/tex]
Therefore, (3, 7) is not a solution.

Hello There!
The slope is the change in y over the change in x
In the table as y goes up 4 x goes up 1
so the slope is 4/1 or 4

Quick easy question!
What is the total surface area of the rectangular prism?
please help me with this question
Answer:
[tex]y=-2\\[/tex]
Step-by-step explanation:
Use the values of the unit circle to get the (x,y) when Θ=[tex]\frac{11\pi}{6}[/tex], which is [tex](\frac{\sqrt{3}}{2}, -\frac{1}{2})[/tex].
The cosecant (csc) function is the reciprocal of the sine function, so we take the y value and take the reciprocal of it, which is -2.

Answer:
2) 3 : 15 = 1 : 5
3) 22 : 38 = 11 : 19
4) 2 : 5 = 26 : 65
Step-by-step explanation:
2) 5, 3, 1, 15
3 : 15 = 1 : 5
If you simplify 3 : 15 you get 1 : 5 and 1 : 5 = 1 : 5.
3) 19, 22, 11, 38
22 : 38 = 11 : 19
If you simplify 22 : 38 you get 11 : 19 and 11 : 19 = 11 : 19.
4) 65, 2, 26, 5
2 : 5 = 26 : 65
If you simplify 26 : 65 you get 2 : 5 and 2 : 5 = 2 : 5.

Sandeep uses 1/5 of a cup of vinegar in his salad dressing recipe. How much vinegar would Sandeep use to make 4/5 of a recipe?
Answer:
4 /25
Step-by-step explanation:
Given that :
Cup of vinegar used per recipe = 1/5 cup
Amount of vinegar to be used for 4/5 of a recipe ;
1 cup recipe = 1/5 cup vinegar
4/5 cup recipe = x
Cross multiply :
x = 1/5 * 4/5
x = 4/25 cup
Hence, Sandeep will use 4/25 cup of vinegar

Find the volume of the cone.
13 cm
n = 9 cm
Answer:
V = 1102.7 cm^3
Step-by-step explanation:
1. Volume of Cone Formula
[tex]V=\frac{1}{3}*h*\pi *r^{2}[/tex]
2. Variables: h = 13 cm r = 9 cm
3. Plug in numbers
[tex]V=\frac{1}{3}*13*\pi *9^{2}[/tex]
V ≈ 1102.69 cm^3

Are the events "selecting a female" and "selecting a students who has brown eyes" independent?
Answer:
No, the events are not independent.
Step-by-step explanation:
Suppose that there are two events, A and B.
Such that first happens the event A and then the event B.
If the outcome of event A affects the probabilities for the different outcomes of event B, then the events are dependent.
In this case, if we have only the event "selecting a student who has brown eyes" (at random)
The probability is equal to the quotient between the total number of students with brown eyes, and the total number of students, then this probability is:
P = 91/200 = 0.455...
Now, if we first impose the "selecting a female", now when we want to select a student with brown eyes we will look only at the female students.
In this case, there are 32 with brown eyes and a total of 90 female students, then the probability of selecting a female with brown eyes at random is:
P = 32/90 = 0.355...
So the probability is different, which means that the events "selecting a female" and "selecting a student who has brown eyes" are not independent.
Consider the glven solids with the dimensions shown. Which solids are similar?
A. only figure 1 and figure 2
B. only figure 1 and figure 3
C. only figure 2 and figure 3
D. all three figures
Answer:
A) only figure 1 and figure 2
Step-by-step explanation:
Answer: Choice A) only figure 1 and figure 2
===========================================================
Explanation:
Let's assume that figure 2 is similar to figure 3.
If this is the case, then the horizontal portions would divide to 30/15 = 2, showing that figure 3 has sides that are twice as long compared to figure 2. But then notice that the vertical sides divide to 36/24 = 1.5, which doesn't match with the previous result of 2.
Figures 2 and 3 cannot be similar for that reason.
Also, figures 1 and 3 are not similar either. Note the horizontal portions divide to 30/10 = 3 while the vertical portions divide to 36/16 = 2.25; the results 3 and 2.25 don't match.
We eliminate answers B, C and D. The only thing left is choice A.
-------------------
To verify choice A is true, we divide each corresponding piece like so
Horizontal: 15/10 = 1.5Vertical: 24/16 = 1.5Slanted: 12/8 = 1.5Each division leads to the same result of 1.5, meaning that figure 2's side lengths are 1.5 times longer than the corresponding side lengths of figure 1. So this confirms that figure 1 is similar to figure 2.

if you you have x2 and 10 subtract
x2-10 this is because 2 x 5 is 10
very sorry if wrong
Answer:
b. x²-10
Step-by-step explanation:
Area of the whole square: x² because x*x = x²
area of unshaded area: 5*2 = 10
so shaded area: area of whole square - area of unshaded area
x² - 10

Graph the inequality on a number line z<1 1/4
Answer:
Step-by-step explanation:
The inequality can be seen graphed in the number line that I have created in the attached picture below. As you can see the open circle represents the value 1 1/4 and is an open circle because it is not included in the inequality. This is because the variable z is less than but NOT equal to 1 1/4. Also since z is any number less than 1 1/4 then the number line goes towards negative infinity.
Cube if any odd number is
Answer:
Cube of any odd number is odd.
The cube of odd numbers are always odd. A perfect cube does not end with 2 zeroes. The given statement is false. There are perfect cubes like 8 and 1728 that end with 8.
Select the statement that describes this expression: 10 + fraction 1 over 4x (5 + 3) − 3.
10 more than fraction 1 over 4 of the sum of 5 and 3, then subtract 3
fraction 1 over 4 of 10 times the sum of 5 and 3, minus 3
3 more than 3 plus 5 multiplied by fraction 1 over 4, then add 10
10 times fraction 1 over 4 plus 3 and 5, minus 3

Jet bought a computer that was 20% off. If the original price of the computer was $785, how much did Jet save? How much did Jet pay?
785·20%=157
785-157=628
Answer:
You will pay $628 for a item with original price of $785 when discounted 20%. In this example, if you buy an item at $785 with 20% discount, you will pay 785 - 157 = 628 dollars.
