Could x = - 5 be a solution to the inequality
-6 < 3x + 9 < 21?
Step-by-step explanation:
[tex]3x + 9 = 3( - 5) + 9 \\ = - 15 + 9 \\ = - 6[/tex]
3x+9 is equals to -6 , not more than based on the inequality, but it is lesser than 21.
However, the solution must fulfil both criteria to be a solution to the inequality. Therefore x = -5 is not a solution to the inequality.
find the surface area .NO FILES #2
Answer:
486
Step-by-step explanation:
The solid is a cube. The faces of a cube are 6 congruent squares.

Answer:
y=-x+1
Step-by-step explanation:
Slope intercept form is writing the equation of a line in the form y=mx+c, where m is slope and c is the y-intercept.
The y-intercept, c, is the value of y when the line crosses the y-axis. We can read from the graph that this value is 1. So, c=1
The slope, m, can be found by taking two points from the graph, (x,y) and (X,Y), and using the formula m=(Y-y)/(X-x). Two point on our line in this example are (0,1) and (-1,2):
m=(2-1)/(-1-0)=-1/1
m= -1
Knowing these values, we can write y=mx+c for our equation: y=-x+1
A small town has 2,500 residents. In a random sample of 125 residents, 2 have the flu. Predict the number of residents of the town who have the flu.
A. 400
B. 20
C. 200
D. 40
Answer:
20
Step-by-step explanation:
40 is the number of residents of the town who have the flu.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, we have,
A small town has 2,500 residents.
In a random sample of 125 residents, 2 have the flu.
i.e. in 2500 residents have flu = 2500*2/125
=5000/125
=40
Hence, 40 is the number of residents of the town who have the flu.

You have a handfull of loonies and quarters in your hand. In total, there are 20 coins and the value of all of these coins equals $14.75. How many loonies and how many quarters do you have?
Answer:
You have 13 loonies and 7 quarters.
Step-by-step explanation:
Given that you have a handfull of loonies and quarters in your hand, and in total, there are 20 coins and the value of all of these coins equals $ 14.75, to determine how many loonies and how many quarters do you have the following calculation must be done:
Loonie = 1
Quarter = 0.25
1 - 0.25 = 0.75
20 x 0.25 = 5
14.75 - 5 = 9.75
9.75 / 0.75 = 13
13 x 1 + 7 x 0.25 = X
13 + 1.75 = X
14.75 = X
Therefore, you have 13 loonies and 7 quarters.

Average mido Find the mean, median, and range of the following data items: 74, 75, 78, 84,94 18 20 84 78 81 82.5 Mean Median Range
Answer:
18: mean = 70.5
median = 76.5
range = 76
20:
mean = 70.83
median = 76.5
range = 76
84:
mean = 81.5
median = 79.5
range = 20
78:
mean = 80.5
median = 81
range = 20
81:
mean = 81
median = 80.25
range = 20
82.5:
mean = 81.5
median = 80.25
range = 20
Step-by-step explanation:
mean = average = sum of numbers / amount of numbers present
median = middle number (arranged least to greatest)
range = largest number - smallest number

In case the picture blurs
Top angle = x + 63
Left angle = x + 96
Right angle = x + 149
Answer:
∠A = 58°
Step-by-step explanation:
all triangles contain 180°
180° - 149° = 31°
x + 63° + x + 96° + 31° = 180°
combine like terms:
2x + 190° = 180°
2x = -10°
x = -5°
∠A = -5° + 63° = 58°
Gina and Marty are selling tickets for the school dance. On Monday, they sold 15 tickets, on Tuesday 23, on Wednesday 20, and on Thursday 32. What was their average daily income if each ticket cost $2.00?
Answer:
$45
Step-by-step explanation:
15×2=30
23×2=46
20×2=40
32×2=64
30+46+40+64=180
180÷4=45
Average=45
Answer:
Their average daily income would be 45 dollars a day.
Step-by-step explanation:
To solve this, add the 15 tickets, 23, 20, and 32 tickets from Monday to Thursday. This should get you a total of 90 tickets. Since each ticket cost 2 dollars, multiply the 90 by 2. This should get you 180. TO find the average, you must divide the total(180) by the amount of days(4) that passed. This should get you 45.
Answer:
45$

A 6 inch personal pizza has 620 calories, with 240 of those from fat. A 12 inch pizza is cut into 8 slices. Estimate the number of calories in one slice of a 12 inch pizza.
9514 1404 393
Answer:
310 calories (120 from fat)
Step-by-step explanation:
A 12-inch pizza has double the diameter of the 6-inch pizza, so will have 2² = 4 times the area. 1/8 of that pizza will have 4/8 = 1/2 the area of the personal pizza. If calories are proportional to the area, then the slice will have ...
(1/2)(620 calories) = 310 calories . . . in 1 slice of 12-in pizza
Mr. & Mrs. Dargen spent $46.25 on a meal, about how much should they
leave for a 18% tip?
Answer:
$8.32
Step-by-step explanation:
I found one percent of 46.25 ( which was 0.4625) by dividing it by 100 then i multiplied that number by 18 in order to get how much the 18% tip would be. From that I got 8.325 but since this is in a currency the answer would be 8.32

Hay 12 canicas en una bolsa y 6
de ellas son verdes. Si se elige
una canica, ¿cuál es la
probabilidad de que sea verde?
Answer:
50%.
Step-by-step explanation:
Dado que hay 12 canicas en una bolsa y 6 de ellas son verdes, para determinar la probabilidad de que si se elige una canica al azar, esta sea verde, se debe realizar el siguiente cálculo:
6 / 12 = X
0.5 = X
0.5 = 50/100
50/100 = 50%
Así, hay un 50% de probabilidades de que, eligiendo una canica al azar dentro de la bolsa, la canica elegida sea verde.
Naomi's fish is 40 millimeters long. Her guinea pig is 25 centimeters long.
How much longer is her guinea pig than her fish?
Explanation 1:
Her guinea pig is
25 cm long.
25 cm = 250 mm
Her fish is 40 mm long, so her guinea pig is longer than her fish by
25 cm − 40 mm = 250 mm − 40 mm = 210 mm= 21 cm
Explanation 2:
First, lets convert the length of Naomi's guinea pig from cm to mm.
1 cm=10 mm
We can multiply each side of the equation by 25 to obtain the length of the guinea pig in mm.
25 × 1 cm = 25 × 10 mm
25 cm = 250 mm
Because we have a length of the guinea pig and the fish in a common metric we can subtract the two values: 250 mm − 40 mm = 210 mm The guinea pig is 210 millimeters longer than the fish. Or, if we want to convert this to centimeters we can divide by 10: 210 millimeters 10 = 21 centimeters
Hope this helps have a good day/night!
