Answer:
11.2 units
Step-by-step explanation:
From (-7, -7) to (-2, 3) is 5 units horizontally and 10 units vertically. Thus we have a right triangle with sides 5 and 10 respectively. The length of the hypotenuse of this triangle is the distance between (-2, 3) & (-7, -7):
d = √(5² + 10²) = √(25 + 100) = √125 = √25√5, or 5√5.
This is approximately 11.2 units

Last week, Russell bought 8 pizzas and 10 cakes for a total of $160.
Today, Russell bought 26 pizzas and 8 cakes for a total of $226.
Assuming neither item has changed in price, what is the cost of a pizza in dollars?
Answer:
$5
Step-by-step explanation:
Create a system of equations where p is the cost of a pizza and c is the cost of a cake
8p + 10c = 160
26p + 8c = 226
Solve by elimination by multiplying the top equation by -4, and the bottom equation by 5
-32p - 40c = -640
130p + 40c = 1130
Add these together:
98p = 490
p = 5
So, the cost of a pizza is $5

Vertical: IJH and KJG
Step-by-step explanation:
The correct options are given below,
Supplementary: AKB and BKG
Complementary: FGE and EGD
Vertical: IJH and KJG
What are lines and angles?Straight lines with little depth or width are present. You will learn about a number of lines, including transversal, intersecting, and perpendicular lines.
A figure called an angle is one in which two rays originate from the same point. In this area, you could also encounter contrasting and related viewpoints.
Given that there are different lines crossing each other at different angles. The value of the different angles can be named as,
A pair of supplementary angles: AKB and BKG
A pair of complementary angles: FGE and EGD
A pair of vertical angles: IJH and KJG

Coach Rivas can spend up to $750 on 30 swimsuits for the swim team. The inequality shown can be used to find the maximum amount in dollars she can spend on each swimsuit. 30p≤750 which inequality represents all the possible values of p,the amount of money in dollars coach Rivas can spend on each swimsuit
Answer:
$0 < p ≤ $25
Step-by-step explanation:
We know that coach Rivas can spend up to $750 on 30 swimsuits.
This means that the maximum cost that the coach can afford to pay is $750, then if the cost for the 30 swimsuits is C, we have the inequality:
C ≤ $750
Now, if each swimsuit costs p, then 30 of them costs 30 times p, then the cost of the swimsuits is:
C = 30*p
Then we have the inequality:
30*p ≤ $750.
To find the possible values of p, we just need to isolate p in one side of the inequality.
So we can divide both sides by 30 to get:
(30*p)/30 ≤ $750/30
p ≤ $25
And we also should add the restriction:
$0 < p ≤ $25
Because a swimsuit can not cost 0 dollars or less than that.
Then the inequality that represents the possible values of p is:
$0 < p ≤ $25
A greeting card cost four dollars before tax. A customer has a 15% discount. Then the 5% sales tax is added. How much will the customer pay for the card?
Given:
Greeting card cost before tax = $4
Discount = 15%
Sales tax = 5%
To find:
How much will the customer pay for the card?
Solution:
It is given that the cost of the greeting card before tax is $4.
After 15% discount, the cost of the greeting card is:
Cost of card after discount [tex]=4-\dfrac{15}{100}\times {4}[/tex]
[tex]=4-0.6[/tex]
[tex]=3.4[/tex]
The cost of card after 5% sales tax is:
Cost of card after tax [tex]=3.4+\dfrac{5}{100}\times 3.4[/tex]
[tex]=3.4+0.17[/tex]
[tex]=3.57[/tex]
Therefore, the customer will pay $3.57 for the greeting card.

Answer:
#1) x=38
#2) x=12
Step-by-step explanation:
For (1)
Since its a triangle we know that all 3 interior angles added up is gonna eqaul 180 degrees. So we already have 2 angles which are 21 and 17. You add those up and you’d get 38. Now since the final angles is unknown we can just make a simple equation of 38+x=180 since we know 2 angles and we need 1 more and a triangle is 180 degrees alli ddded up together. You’d get 142 for that angle. X is adjacent to that angle and they form a straight line so it also has to be 180. We got 1 side and so we subtract 180-142= 38. X will be 38.
For (2)
Since its 2 parallel lines cut by a transversal and we have two same side interior angles we know its gonna be supplementary Which means that both those angles added up will be 180. Now we have the two different angles so we add them up and solve for x. (10x+17)+(3x+7)= 180. Commbine like terms which will turn out to be 13x+24=180. Subtract 24 on both sides. 13x= 156. Solve for x by diving 13 on both sides which will lead to x= 12

Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
The given possible roots have the form that we'd get by using the quadratic formula, so let's start with that. Here the coefficients are {2, -6, 3}, and so the discriminant (b^2 - 4ac) is (-6)^2 - 4(2)(3), or 36 - 24 = 12.
Because the discriminant is positive we know immediately that there are two different real roots.
-(-6) ± √12 6 ± √12

D.
(40 + 50) + (6 + 1) + (0.6 + 0.1) + (0.05 + 0.02)
Answer:
A) (40 + 50) + (6 + 1) + (0.6 + 0.5) + (0.01 + 0.02)
Step-by-step explanation:
In this case, you are breaking each term down to it's non-zero digits, and adding them:
46.61 = 40 + 6 + 0.6 + 0.01
51.52 = 50 + 1 + 0.5 + 0.02
Note however, that the answer choices add each individual non-zero terms together:
(40 + 50) + (6 + 1) + (0.6 + 0.5) + (0.01 + 0.02), or A)
A) (40 + 50) + (6 + 1) + (0.6 + 0.5) + (0.01 + 0.02) is your answer.

In Orlando Florida the high temperature was 85 degrees Fahrenheit on Saturday and 79 degrees Fahrenheit on Sunday what is the percent of change in the high temperature from Saturday to Sunday to the nearest whole percent
Answer:
[tex]7\%[/tex]

Initial temperature = 85 degrees Fahrenheit
Final temperature = 79 degrees Fahrenheit
Percentage change in temperature is given by
[tex]\dfrac{|\text{Final temperature}-\text{Initial temperature}|}{\text{Initial temperature}}\times 100\%\\ =\dfrac{|79-85|}{85}\times 100\%\\ =7.05\approx 7\%[/tex]
