Answer:
no solution
Step-by-step explanation:
if you simplify it all then you have to flip creating 50 = 49
The variable got eliminated. Then inequality –7(3x – 7) + 21x ≥ 50 has no solution.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The inequality is given below.
–7(3x – 7) + 21x ≥ 50
Simplify the inequality, then we have
–7(3x – 7) + 21x ≥ 50
–21x + 49 + 21x ≥ 50
–21x + 49 + 21x ≥ 50
–21x + 21 ≥ 1
The variable got eliminated. Then inequality –7(3x – 7) + 21x ≥ 50 has no solution.

Valerie's younger sister is 3 ft 2 in. tall. if her sister grows an additional 32 inches how tall will she be
Answer:
6 feet 4 inches
Step-by-step explanation:
Step-by-step explanation:
3 FEET 2 INCHES These are not the same! Do not multiply
Each foot is 12 inches. So 3 times 12 (3 feet) is 36, add the extra 2 inches for 38 inches.
38 plus 32 equals 70 total inches. NOw we put it back into feet.
70 divided by 12 is 5, remainder 10.
So Valerie's sister will be 5 feet 10 inches (G)

Step-by-step explanation:
David’s garden produced six bushels of zucchini, three bushels of beans, seven bushels of corn, and four bushels of beets. In the table below, write the fraction (in simplest form) and the percent of David’s total crop that each vegetable represents.
Answer:
Step-by-step explanation:
Zucchini = 'z' = 6
Beans = 'b' = 3
Corn = 'c' = 7
beets = 't' = 4
Total produce = 20 bushels of veggies.
z = 6/20 = 3/10 % = 3/10*100 = 30%
b = 3/20 % = 3/20 * 100 = 15%
c = 7/20 % = 7/20 *100 = 35%
t = 4/20 = 1/5 % = 1/5 * 100 = 20%
Total 100%

Frederick headed for Lutzen at 3 kph. Later he increased his speed to 4 kph. If it was 52 kilometers to Lutzen and the total time of travel was 15 hours, how long did he travel at 3 kph?
Since distance is equal to rate times time:
Let x= the time traveled at 3 km/h
Let y= the time traveled at 4 km/h
We can say that
3x+4y=52
Or that three (kilometers) times the time traveled at 3 kilometers an hour plus 4 (kilometers) times the time traveled at 4 kilometers an hour is equal to 52; the total distance traveled.
Likewise, we can see that:
x+y=15
Because x, the number of hours traveled at 3 km/h added to y, the time traveled at 4 km/h is equal to 15; the total time traveled.
Now, I'll solve by substitution.
x=-y+15
Substitute that into the other equation.
3(-y+15) + 4y = 52
Distribute
-3y + 45 + 4y = 52
Combine like terms
y + 45 = 52
Minus 45 from both sides
y = 7
So Fredrick traveled at 4 km/h for 7 hours.
Now, to find the other value, substitute the value of y into one of the original equations.
x + 7 = 15
Minus 7
x = 8
So
Time traveled at 4 km/h = 7 hours
Time traveled at 3 km/h = 8 hoursSince distance is equal to rate times time:
Let x= the time traveled at 3 km/h
Let y= the time traveled at 4 km/h
We can say that
3x+4y=52
Or that three (kilometers) times the time traveled at 3 kilometers an hour plus 4 (kilometers) times the time traveled at 4 kilometers an hour is equal to 52; the total distance traveled.
Likewise, we can see that:
x+y=15
Because x, the number of hours traveled at 3 km/h added to y, the time traveled at 4 km/h is equal to 15; the total time traveled.
Now, I'll solve by substitution.
x=-y+15
Substitute that into the other equation.
3(-y+15) + 4y = 52
Distribute
-3y + 45 + 4y = 52
Combine like terms
y + 45 = 52
Minus 45 from both sides
y = 7
So Fredrick traveled at 4 km/h for 7 hours.
Now, to find the other value, substitute the value of y into one of the original equations.
x + 7 = 15
Minus 7
x = 8
So
Time traveled at 4 km/h = 7 hours
Time traveled at 3 km/h = 8 hours

Two lines intersecting at a right angle ?
Answer:
are perpendicular
Yes, it is perpendicular
Parallel is when you have two lines that do not intersect
A ray is a line that has one definite starting point and no obvious end point. (Stars with a point and "ends" with an arrow, meaning that it goes on "forever")
A line is just one specific line
When you have perpendicular, that is when two lines cross each other forming a right angle as you may now know

A set of data has a normal distribution with a mean of 49 and a standard deviation of 8. Find the percent of data within the following interval. from 33 to 65.
Answer:
95 percent
Step-by-step explanation:
The empirical rule states that approximately 95% of observations will fall within 2 standard deviations of the mean if the population is approximately symmetrical(normal) in distribution.
The interval from 33 to 65 falls within 2 standard deviations of the mean;
49-2(8) = 33
49+2(8) = 65
Thus, 95 percent of data will fall within the interval from 33 to 65

Find the mean absolute deviation. Round to the tenth
Answer:
1) 1.8 round to tenths
Step-by-step explanation:
To find the mean absolute deviation we follow these steps:
Find the mean value by adding all data values and dividing by number of data valuesFind the absolute value of the difference between each data value and the mean: | data value – mean. | Divide the sum of the absolute values of the differences by the number of data values1) 4,5,10,8,4,8,7,6
step 1
4+5+10+8+4+8+7+6 / 8 = 6.5
Mean (μ): 6.5
step 2
|4-6.5| + |5-6.5| + |10-6.5| + |8-6.5| + |4-6.5| + |8-6.5| +|7-6.5| + |6-6.5| = 14
step 3
14 / 8 = 1.75
Repeat these steps for other parts.

Select all the expressions equivalent to 3.1⁴.
Answer:
A, B, DStep-by-step explanation:
[tex]3.1^4=(3.1)(3.1)(3.1)(3.1)\to\boxed{A}\\\\3.1^4=[(3.1)(3.1)](3.1)(3.1)=(9.61)(3.1)(3.1)\to\boxed{B}\\\\3.1^4=[(3.1)(3.1)][(3.1)(3.1)]=(9.61)(9.61)\to\boxed{D}[/tex]
Equivalent expressions to 3.1⁴ involve raising 3.1 to the power of 4. This means 3.1 is multiplied by itself four times, not three times (which would be cubing). The equivalent expression would result from multiplying 3.1 by itself four times.
Explanation:The equivalent expressions to 3.1⁴ involve the operation of raising a number to a power. In this case following the number 3.1, the exponent of 4 means that 3.1 is being multiplied by itself four times, and it is not the same as cubing. The cubing of exponentials refers to the process of raising a number to the power of three or multiplying the number by itself three times. The commutative, associative, and distributive laws can be applied to simplify and rewrite exponential expressions. Therefore, to find an equivalent expression for 3.1⁴, you would need to multiply 3.1 by itself four times.
