Solve the equation -10(d + 1) = -14.
d=
?
Answer:
d = 0.4
Step-by-step explanation:
Given
- 10(d + 1) = - 14 (divide both sides by - 10 )
d + 1 = 1.4 ( subtract 1 from both sides )
d = 0.4

The budget for a school dance is $390.00. Decorations and refreshments cost $150.00. The band charges a fee of $100.00 plus an additional $35.00 per hours. What is the maximum number of hours the school can have the band play at the dance?
Answer:
The maximum number of hours the school can have the band play at the dance is 4.
Step-by-step explanation:
150 + 100 + 35x ≤ 390
250 + 35x ≤ 390
subtract 250 from both sides
35x ≤ 140
divide by 35 on both sides
x ≤ 4

(-3x2 + 6x - 12) + (5x + 9) is equivalent to expression __
Answer:
[tex]-3x^{2}+11x-3[/tex]
Step-by-step explanation:
[tex](-3x^{2}+6x-12)+(5x+9) = -3x^{2} + 6x - 12 + 5x + 9 = -3x^{2} + 11x - 3[/tex]
Answer:
see below
Step-by-step explanation:
Here are the simplified results of each polynomial combination.
(5x2 + 2x + 1) + (6x2 − 3x + 9)
= 5x2 + 2x + 1 + 6x2 − 3x + 9
= 5x2 + 6x2 + 2x − 3x + 1 + 9
= 11x2 − x + 10 (B)
(-3x2 + 6x − 12) + (5x + 9)
= -3x2 + 6x − 12 + 5x + 9
= -3x2 + 6x + 5x − 12 + 9
= -3x2 + 11x − 3 (A)
(8x + 16) − (3x2 − 3x − 15)
= 8x + 16 − 3x2 + 3x + 15
= -3x2 + 8x + 3x + 16 + 15
= -3x2 + 11x + 31 (D)
(5x2 + 23x − 7) − (x2 − 4x + 21)
= 5x2 + 23x − 7 − x2 + 4x − 21
= 5x2 − x2 + 23x + 4x − 7 − 21
= 4x2 + 27x − 28 (C)

A diver in the Olympics dives off a platform 15 m above the water’s surface and descends to a depth of 5 m below the surface. How many meters are traveled by the diver during the dive ?
Let the water surface be 0.
He starts at 15 and gets to the water surface of 0 so he travels 15 meters.
He then goes 5 meters below the surface.
15 + 5 = 20 total meters.
Answer:
20m
Step-by-step explanation:
the diver starts on a platform 15m above the water surface, which we will call 0. if he goes from the platform to -5m under the water, then he would have traveled 20m.

Which equation could be used to solve for the length of side c, given a = 5, b = 12, and C = 72°?
Answer:
i had this question before
Step-by-step explanation:
c^2=a^2+b^2-2abcos(c)
c=sqrt(a^2+b^2-2abcos(c))
c=sqrt((5)^2+(12)^2-2(5)(12)cos(72))
c=sqrt(25+144-120cos(72))
c=sqrt(169-120cos(72))
c=sqrt(169-37.08)
c=sqrt(131.92)
c=11.49
Find the inverse of each function:
g(x)=[tex]\frac{-5x+5}{2}[/tex]
A. g^{-1}[/tex](x)=[tex]\frac{5-2x}{5}[/tex]
B. g^{-1}[/tex](x)=[tex]4+\frac{4}{3}x[/tex]
C. g^{-1}[/tex](x)=[tex]\frac{10-x}{2}[/tex]
D. g^{-1}[/tex](x)=[tex]-4+\frac{1}{3}x[/tex]
Answer:
Step-by-step explanation:
Replace g(x) with y, then switch the x and y variables:
[tex]x=\frac{-5y+5}{2}[/tex]
Solve for the new y value, multiply by 2:
[tex]2x=-5y+5[/tex]
Subtract 5 on both sides:
[tex]2x-5=-5y[/tex]
Divide by -5 on both sides:
[tex]-\frac{2x-5}{5} =y[/tex]
Distribute the negative sign and rearrange:
[tex]\frac{-2x+5}{5} =\frac{5-2x}{5} =g^-^1(x)[/tex]
Answer:
A. g⁻¹(x) = (5 - 2x)/5Step-by-step explanation:
Given functiong(x) = (-5x + 5)/2Find the inverse of g(x)SolutionSubstitute x with y and g(x) with x and then solve for y:
x = (-5y + 5) /22x = -5y + 55y = -2x + 5y = (-2x + 5)/5y = (5 - 2x)/5Replace y with g⁻¹(x)
g⁻¹(x) = (5 - 2x)/5Correct choice is A

Answer:
217.98 is greater.
Step-by-step explanation:
Think about this way. Which is the larger number, 217 or 21? 217, of course. The decimal point only adds a small fraction of a number to the whole, so it doesn't affect the value that much.

sarah used 2.5 cups of cheese in a dish that serves 10 people amyn used 1.6 cups of cheese in a dish that serves 8 people how much more cheese is in one serving of sarahs dish
Answer:
[tex]\frac{1}{20}[/tex] more cheese in Sarah's dish than Amyn.
Step-by-step explanation:
To find this, we need to get the two fractions, [tex]\frac{2.5}{10}[/tex] and [tex]\frac{1.6}{8}[/tex] to a common denominator. The closest one is a multiple of 4 for [tex]\frac{2.5}{10}[/tex] and a multiple of 5 for [tex]\frac{1.6}{8}[/tex] .
This makes both fractions much more comparable, and we have
[tex]\frac{10}{40}[/tex] for Sarah's dish
[tex]\frac{8}{40}[/tex] for Amyn's dish.
Knowing Sarah has [tex]\frac{2}{40}[/tex]'s more cheese in her dish, we can still simplify, so after dividing 40 by 2, we get [tex]\frac{1}{20}[/tex], the simplest form of how much more cheese Sarah has in her dish than Amyn,

Choose one kind of triangle to use for a tessellation: equilateral, isosceles, or scalene.
• Use technology or paper to create six or more congruent copies of your chosen triangle and investigate how the shape tessellates.
• Use your chosen triangle to create an artwork with tessellations. You can use any sizes, colors, patterns, or art mediums. You can submit a scanned copy, photo, screenshot, or snip of your artwork.
• Provide the explanation of the math behind your tessellation that the gallery will display next to your artwork.
o Use the definition of your chosen triangle and what you know about the interior angles of triangles to prove that any version or size of that triangle will tessellate. (Hint: Study the interior angles where the vertices meet in the tessellation.)
o Include diagrams or other visual models to help explain your proof.
o Think about how you could extend your work to prove that all triangles
tessellate, and share any theories you might have.
Your completed work of art will be submitted as your portfolio assessment. It must include your tessellation art and your explanation for the math behind it.

4) Part A: A biologist counted the number of two types of salmon (Chanook and Steelhead) at a dam. He used the table below to record the number of salmon on different days. On day 5, the biologist counted 16 Chinook. If the ratio of Chinook to Steelhead remained the same as on the previous four days, how many Steelhead should the biologist expect to count on day 5? Record your answer below. *
Captionless Image
Answer:
The answer is 40
Step-by-step explanation:
He expects to count #####################################
There are 12 Steelhead should the biologist expect to count on day 5.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
The ratio of Chinook to Steelhead on the first four days is 4:10.
If this ratio remained the same on day 5, then we can expect the biologist to count of the salmon as Chinook.
On day 5, the biologist counted 16 Chinook,
Let x Steelhead would be the biologist expected to count on day 5.
As per the given question, the required solution would be as:
4/10 = 16/x
x = 16 × 10 / 4
x = 160/4
x = 40
Hence, there should be 40 Steelhead.
