The base of a regular pyramid is a hexagon
12 cm 30°
a
What is the area of the base of the pyramid?
Answers
Answer:
Below in bold.
Step-by-step explanation:
The hexagon is made up of 6 equilateral triangles.
So the Base = 12 cm.
Height a = 12 cos 30 = 10.392 cm
So area of 1 triangle = 1/2 * 12 * 10.392 cm^2
- and total area = 6 * 1/2 * 12 * 10.392
= 36 * 10.392
= 374.11 cm^2 to the nearest hundredth.

A quadratic equation of the form 0=ax2 bx c has a discriminant value of -16. how many real number solutions does the equation have?
Answers
The quadratic equation will have no real solutions.
Given quadratic equation is: [tex]ax^{2} +bx+c=0[/tex]
What is the discriminant of a quadratic equation?The discriminant(D) of a quadratic equation is [tex]D=b^{2}-4ac[/tex]. It depicts the nature of the roots.
[tex]D > 0[/tex] the roots are real and distinct.
[tex]D=0[/tex] the roots are real and equal.
[tex]D < 0[/tex] the roots will be imaginary.
We have [tex]D=-16[/tex] which is negative.
So, the roots will be imaginary.
So, the given quadratic equation will have no real solutions.
Hence, the given quadratic equation has no real solutions.

It takes you 1/4 hours to walk 1/3 of a mile.
How long will it take you to walk 2 1/2? Miles?
PLS HELP ASAP
Answers
Answer:
15/8 Hours
Step-by-step explanation:
To start, I would find see how long it takes to walk a mile.
1/3 · 3 = 1
1/4 · 3 = 3/4
So we now know that walking one mile takes 45 minutes. Next, I multiplied 1 mile by 2.5 and repeated the same process with the time.
3/4 · 5/2 = 15/8
Therefore, it takes 15/8 hours to walk 2.5 miles.

what are rational. numbers?
Answers
Rational numbers are defined as "a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q." This quote can be broken down to make it easier to understand. In basic terms, a rational number is a real number that is an integer, fraction, terminating decimal, or repeating decimal.
Integer
An integer is any positive or negative whole number including 0. Examples of integers include 4, -9, and 0.
Fraction
All fractions that do not have a 0 denominator (which makes the number undefined) are rational numbers. Additionally, complex fractions are not always considered rational numbers. Complex fractions are fractions where either the numerator or denominator is a decimal or fraction itself. Examples of rational fractions include [tex]\frac{4}5}[/tex], [tex]\frac{7}{4}[/tex], and [tex]\frac{2}{2}[/tex].
Terminating Decimals
Terminating decimals are decimals that have a finite number of digits. This means that the decimal stops at some point. Examples of terminating decimals include 0.346, 0.47834, and 0.345832454525456
Repeating Decimals
Repeating decimals are any decimal that is not terminating but has some pattern that repeats for infinity. Examples of repeating decimals include [tex]0.\bar 9[/tex], [tex]0.\bar8\bar6[/tex], and [tex]0.\bar 5\bar7\bar8\bar4[/tex]. In this case, the bar notation represents numbers that repeat forever.

Lindsey purchased one pet carrier that $21.89 and two bags of cat food that cost $16.46 each what was the total cost of these items?
Answers
Answer:
[tex]\huge\boxed{\sf \$54.81}[/tex]
Step-by-step explanation:
The cost of pet carrier = $21.89
The cost of 1 bag of cat food = $16.46
The cost of 2 bags of cat food = $16.46 × 2
= $32.92
Total cost:
= $21.89 + $32.92
= $54.81
[tex]\rule[225]{225}{2}[/tex]
[tex] \text{Cost of one pet carrier =}[/tex]$21.89

Hope This HelpsUse the distributive property and then simplify the expression.
3(x-8)+6(x+4)
Answers
Answer: 9x
Explanation: Distributive property basically multiplies the numbers inside the parentheses by the number outside of them.
So, in this case, to simplify both parts of the equation, you’d have to multiply “x” and “8”by 3, and the other “x” and “4” would be multiplied by 6.
3 times “x” would be 3x, and 3 times “-8” would be -24. So the first part simplified would be: -24+3x.
Now for the second part, 6(x+4). We’d multiply “x” and “4” by 6. This would get us 6x and 24.
Now to simplify. We currently have the expression “(-24+3x)+(6x+24)”.
As -24 and 24 cancel each other out, the only things we would have left to simplify would be 3x+6x.
3x+6x is equal to 9x.
So there’s how you’d get your answer of 9x!
Hopefully this was explained easy enough for you! If not, please comment!

Answers
There were 8 people who surveyed exercise once a week or less out of the 50 people who were surveyed.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
From the circle graph, percentage of the people surveyed exercise once a week or less = 100% - (10% + 40% + 20% + 14%) = 16%
Number of the people surveyed exercise once a week or less = 15% of 50 = 0.16 * 50 = 8
