Find the surface area of a right square pyramid with base edge length
2 feet and height 5 feet.
Answer:
24.4 sq. ft.
Step-by-step explanation:
Area of a right square pyramid is:
A = a^2 + 2(a)*square root of ((a^2/4) + b^2)
A = 4 + 4 (square root of ((4/4) + 25) = 4 + 4* square root of 26
A = 4 + 4*5.099
A = 4 + 20.396
A = 24.396 sq ft.

Four student government officers want to go to the state convention. It will cost them $100 for registration, $375 for transportation and food, and $41 per person for the hotel. There is $425 budgeted for the convention in the student government savings account. They can earn the rest of the money they need by having a car wash. If they charge $5 per car, how many cars must they wash in order to have enough money to pay for the trip?
cars___?
Answer:
$100 + $375 + $41(4) = $516
$516 - $425 = $91
$91 / $5 = 18.2 cars
Therefore, the four student government officers must wash 18 cars in order to have enough money to pay for the trip.

P(-3,6) y el intercepto =-10, encontrar la pendiente
The slope of the line, given the point on the line and the y - intercept, is - 5. 33
How o find the slope ?The slope of a line tells us the relationship between the dependent variable and the independent variable. In other words, it tells us what a change in the independent variable leads to in the dependent variable.
The slope can be found in the slope - intercept formula form of :
y = mx + b
m is the slope
b is the y - intercept
We have the y - intercept and a y and x value in ( -3, 6 ) so the slope is:
6 = - 3 ( m ) + ( - 10 )
6 = - 3m - 10
- 3m = 6 + 10
- 3 m = 16
m = 16 / - 3
m = - 5. 33

The ratio 81:108 in the simplest form
The ratio 81:108 can be simplified to 9:13. To find the simplest form of the ratio, you can divide both numbers by the greatest common factor. The greatest common factor of 81 and 108 is 9, so you can divide both numbers by 9 to get the simplified ratio of 9:13.
What is the value of m in the figure below? If necessary , round your answer to the nearest tenth of a unit
Using the concept of similar triangles, the value of m to the nearest tenth of a unit in the given figure is 6.71.
What are similar triangles?Triangles with the same geometry but different sizes are said to be similar triangles. Examples of related objects are all equilateral triangles and squares with any side length. In other words, two triangles that are similar have corresponding sides that are proportionate equal and corresponding angles that are similar.
From the concept of the similar triangle,
3/BD = BD/12
BD² = 12 × 3
BD² = 36
As triangle BDC is a right-angled triangle, use Pythagoras' theorem
m² = BD² + 3²
m² = 36 + 9
m² = 45
m = √45
m = 6.708
m ≈ 6.71

according to a recent article about individuals who have credit cards, the mean number of cards per person with credit cards is 4. To test this results a random survey of 60 individuals who have credit cards were conducted. The survey only includes the number of credit cards per participant
Answer:
The variable of interest is NUMBER OF CREDIT CARDS. it is a QUANTITATIVE variable.
u=4
u<4
use a t1-84 go to stat, edit, input the table set into L1, back to stat, tests, t-test, data, u=4, list:L1, u<, calculate, enter that will give you a t0=-.62
p-value is in the range P-value>0.10
The P-value is GREATER than level of significance. DO NOT REJECT the null hypothesis. there IS NOT sufficient evidence to claim that the mean number of credit cards is LESS THAN 4.
Step-by-step explanation:
a. The first question in the study asked for the variable of interest. The variable is number of credit per participants. This variable is quantitative.
What is the hypothesis?The null hypothesis has H0: u = 4
Alternative hypothesis = H1: u < 4
To solve the for the p value and the test statistic, more data would be needed for this question.

Find the coordinates of the circumcenter of the triangle with the given vertices.
L(3,−6), M(5,−3), N(8,−6)
P(1.6,-2.9) are the coordinates of circumcentre of the triangle
How to find the coordinates of the circumcenter of a triangle?The circumcenter of a triangle is the point where the perpendicular bisectors of the sides of that particular triangle intersect.
Let L(3,−6), M(5,−3), N(8,−6) be the vertices of the given △LMN.
Let P(x,y) be the circumcentre of △LMN. Then,
PL = PM = PN
Also, PL² = PM² = PN²
PL² = PM²
(x-3)² + (y-(-6))² = (x-5)² + (y-(-3))²
(x-3)² + (y+6)² = (x-5)² + (y+3)²
x²-6x+9 + y²+12y+36 = x²-10x+25 + y²+6y+9
4x + 6y = -11 ---- (1)
Also, PM² = PN²
(x-5)² + (y-(-3))² = (x-8)² + (y-(-6))²
(x-5)² + (y+3)² = (x-8)² + (y+6)²
x²-10x+25 + y²+6y+9 = x²-16x+64 + y²+12y+36
6x - 6y = 27 ---- (2)
Solve (1) and (2) simultaneously by elimination:
6 × (4x + 6x = -11)
4 × (6x - 6y = 27)
24x + 36y = -66
24x - 24y = 108
subtract:
60y = -174
y = -174/60
y = -2.9
Put y = -2.9 into (1):
4x + 6x = -11
4x + 6(-2.9) = -11
4x - 17.4 = -11
4x = 6.4
x = 1.6
Thus, the coordinates of the circumcentre of △LMN are P(1.6, -2.9)

Leo wants to buy some shoes. He found the shoes at two different stores for a price of $35.
The stores are each having a sale.
- Store X is offering 15% off the price of the shoes.
- Store Y is offering $5 off the price of the shoes.
Calculate the difference between the total of the price for the shoes?
Answer:
$3.50
Step-by-step explanation:
Store X:
0.15*35 = 5.25
35-5.25 = 29.75 dollars
Store Y:
0.05*35 = 1.75
35-1.75 = 33.25 dollars
Total difference:
33.25-29.75 = 3.50 dollars

Round your answer to the nearest hundredth.
Answer:
[tex]x = \± 0.82[/tex]
[tex]y =-3.18 \ or\ -4.82[/tex]
Step-by-step explanation:
Given
[tex]y = 3x^2 + x - 6[/tex]
[tex]y = x -4[/tex]
Required
The solution
First, we equate both expressions.
[tex]y = y[/tex]
[tex]3x^2 + x - 6 = x - 4[/tex]
Subtract x from both sides
[tex]3x^2 - 6 = - 4[/tex]
Add 6 to both sides
[tex]3x^2 = 2[/tex]
Divide both sides by 3
[tex]x^2 = 0.667[/tex]
Solve for x
[tex]x = \± \sqrt{0.667[/tex]
[tex]x = \± 0.82[/tex]
To solve for y, we have:
[tex]y = x -4[/tex]
This gives
[tex]y = \± 0.82 - 4[/tex]
Split
[tex]y = 0.82 - 4 \ or\ -0.82 - 4[/tex]
[tex]y =-3.18 \ or\ -4.82[/tex]

how to work XYZ company's cost function for the next four months is c=500,000+5Q .. If, because of strike, the most the company can produce is br. 100,000 units, should it shutdown? Why or why not?
Answer:
(A) So since BE means cost = revenue, you just need to solve
6Q = 500,000 + 5Q
(B) they told you at the top what the 4-month cost is. That is still true, even if Q=0
(C) find revenue for 100,000. If less than cost, shut down.
