Answer:
the answers are 12.5, 5, 2, 0.8 and 0.32
Step-by-step explanation:
2(0.4)^-2
=2(6.25)
= 12.5
2(0.4)^-1
= 2(2.5)
=5
2(0.4)^0
=2(1)
=2
2(0.4)^1
=2(0.4)
=0.8
2(0.4)^2
=2(0.16)
=0.32

Answer:
54 sq ft
Step-by-step explanation:
6ft x 3 ft = 18 sq ft
9 ft x 4 ft = 36 sq ft
18 sq ft + 36 sq ft = 54 sq ft
The choices should be in sq ft, not in sq cm
The value of area in sq cm would be far greater than the value of area in sq ft.

The linear graph shows the possible combinations of cakes and pies a club must sell to meet their fundraising goal. What is the domain of the graph? A) {x: 0 < x < 40} B) {x: 0 ≤ x ≤ 40} C) {x: 0 < x < 20} D) {x: 0 ≤ x ≤ 20}
Answer:
[tex]\{x: 0 \le x \le 40 \}[/tex]
Step-by-step explanation:
Given
See attachment for graph
Required
The domain of the graph
To do this, we simply write out the range of value of the x-coordinate.
From the attached graph, the x values are:
[tex]x = [0,40][/tex] i.e. from 0 to 40 (both inclusive)
So, the domain is:
[tex]\{x: 0 \le x \le 40 \}[/tex]
Fritz is recording the decay of radioactive material. The table displays the
number of weeks and the level of radioactivity he measures each week.
What will be the level of radioactivity in 10 weeks?
Answer:
Every week, the radioactivity decreases by a factor of 5
After 1 week, it goes from 5,000 to 1,000
2 weeks 1,000 / 5 =200
3 weeks 200 / 5 = 40
4 weeks 40 / 5 = 8
5 weeks 8 / 5 = 1.6
6 weeks 1.6 / 5 = 0.064
7 weeks 0.064 / 5 = 0.0128
8 weeks .0128 / 5 = 0.00256
9 weeks 0.00256 / 5 = 0.000512
10 weeks 0.000512 / 5 = 0.0001024

Find the volume of the triangular prism.
A triangular prism has a height of 6 meters. Its triangular bases have a base length of 4.2 meters. and a height of 2.8 meters.
The volume of the triangular prism is ___
Answer:
V = 35.28 m³Steps:
V = H × (h×bl)/2
V = 6 × (4.2×2.8)/2
V = 6 × 11.76/2
V = 6 × 5.88
V = 35.28 m³
Verify the equation: (sin x + cos x)(tan x + cot x) = sec x csc x
Answer:
The equation (sin(x) + cos(x))(tan(x) + cot(x)) = sec(x)csc(x) is not solvable because the two sides are not equal.
10d = 10,000
solve for D
Answer:
d = 1000 is the correct answer to that question
Answer:
d=4
Step-by-step explanation:
10^d=10000
Solve Exponent.
10d=10000
log(10d)=log(10000) (Take log of both sides)
d*(log(10))=log(10000)
d=
log(10000)
log(10)
d=4

Answer:14 is obtuse
15 is A
Step-by-step explanation:
For 14 the only remaining angle is over 90
For 15 the first triangle has all same side and angle measures
second triangle has 2 equal side measures
and third has none
Answer:
1: Obtuse
2: A
Step-by-step explanation:
One angle is 57° and another is 12°. If we add them, we get 69. Subtract 69 from 180 to get missing angle: 180-69=111
the missing angle is 111°. We know this is not a right triangle because those have a 90° angle. Since one angle is bigger than 90 (111°), the triangle is obtuse.
For the second one, we see that the first triangle is equal on all sides, so it is equilateral. The second triangle has just two equal sides, so it is isosceles. The thrid one is different side length on all of them, so it is scalene. the answer is A.
HELPPP PLSSSS ASAPP What is the slope of the line below? If necessary, enter your answer as a
fraction in lowest terms, using the slash (/) as the fraction bar. Do not enter
your answer as a decimal number or an equation.
(2,2) (-1,-4)
Answer:
2
Step-by-step explanation:
The formula to find the slope given 2 points is y2-y1/x2-x1. Now lets plug in the numbers. (2,2) is the first set of points and (-1,-4) is the second set of points. So we have -4-2/-1-2. We have -6/-3. Now we must simplify, giving us 2.

Find the total surface area shown down below
Ignore the colors!
Part A is already answered
Part B asks: What is the length of the hypotenuse?
Answer:
52
Step-by-step explanation:
Using the Pythagorean theorem
a^2+b^2 = c^2
20^2 + 48^2 = c^2
400 +2304=c^2
2704=c^2
Taking the square root of each side
sqrt(2704) = sqrt(c^2)
52 = c
Answer:
[tex]hypotenuse^{2}[/tex] = [tex]altitude^{2}[/tex] + [tex]base^{2}[/tex]
[tex]hyp^{2}[/tex] = [tex]48^{2}[/tex] + [tex]20^{2}[/tex]
= 2304 + 400
= 2704
∴[tex]hyp[/tex] = [tex]\sqrt{2704}[/tex]
= 52

A family drinks 2 gallons of milk in 3 days,
At that rate, how many gallons will the family
drink in 15 days?
Answer: This is what I have tried --
5 gallons : 3 weeks = x gallons : 52 weeks
5/3 = x/52 (cross multiply)
3x = 260 (divide by 3)
x = 86.6 or 87 gallons
Step-by-step explanation: hope this is right
Answer:
10 gallons of milk
Step-by-step explanation:
This question is a ration every three days the family drinks 2 gallons of milk (3:2) to find how much they would drink in 15 days all you would have to do is multiple both numbers by 5 to get 15:10. This represents how much milk they drink in 15 days.
how do you solve for the x ?
Answer:
x = -8
Step-by-step explanation:
these angles are vertical, therefore they are equal
x + 78 = 70
x = -8
