Answer:
Approximately $1.87 ($1.869)
Step-by-step explanation:
There are 2 ways to do it
1.78 x 1.05 = 1.869 / $1.87
Or
1.78 x .05 = .089
1.78 + .089 = 1.869 / $1.87

(please explain)2. Write the fact families for the number 144,12, and 12.
Answer:
12 x 12 = 144
144 ÷ 12 = 12
Step-by-step explanation:
12 times 12 is 144 and the opposite of multiplication is division, the sum goes in front when you divide
ression x3 + 5x-2 when x = 2.

What is the value of (33 - 2 × 7) + (5 × 3 - 22) ?
Answer:
12
Step-by-step explanation:
Keep in mind the rules of PEMDAS
P (parenthesis)
E (exponents)
M (multiply)
D (division)
A (addition)
S (subtraction)
Because parenthesis is the first operation in PEMDAS, you would start by calculating inside the parenthesis
We can start with the numbers inside the first parenthesis
(33 - 2 × 7)
Start by multiplying 2 and 7 because the M comes before the S
(33 - 2×7)= (33- 14)
Now subtract 14 from 33
(33-14) = 19
Step 2: Calculate inside the second parenthesis
(5 × 3 - 22)
Multiply first
(5 × 3 - 22)= (15 - 22)
Subtract!
(15 - 22)= -7
Now add the final number together
(why? There is an addition sign between the two parenthesis ordering us to add the final numbers together)
19 + (-7)
19-7
12

Write the equation of a line in slope-intercept form that passes through (0, 7) and has a slope of -23.
Answer:
y = -23x + 7
Step-by-step explanation
We are using the equation y = mx + b.
The slope (m) is -23, so it would be y = -23 + b.
b is the y-intercept, and the ordered pair that gives us the y-intercept is (0,7).
Remember that the y-intercept is what the y-coordinate is equal to when the x-coordinate is 0.
Plan A: Pay a $10.00 initiation fee per family, then pay a
discounted price of $1.75 per person to visit the
museum.
Plan B: Pay $2.75 per person per visit to the museum.
For each of the problems below, write an equation to
represent the situation and use the equation to solve the problem.
1. Jayden and his brother choose Plan A. During the summer, they spend a total of $38. How many times did the boys visit the museum?
2. Maria and her sister also like to visit the museum. They choose Plan B and spend a total
of $38.50. How many times did the girls visit the museum?
Step-by-step explanation:
y = the cost of all visits to the meuseum
x = the number of visits
Plan A calls for $1.75 per per, per visit. There are two people so each visit for will cost $3.50 for both. This is the Slope of your line. This plan also requires an initial cost of $10 for 0 visits, this is your y intercept, or b in the point Slope form.
Put all that together for y = 3.5x + 10
The 1st question requires finding the number of visits possible for $38.00, this is the y value at x visits.
Solve
38.00 = 3.5x + 10. Subtract 10 from both sides
28.00 = 3.5x. divide both sides by 3.5
x = 8 visits for each Hayden and his brother.
Plan B is just paying $2.75 per person, per visit. For both Maria and her sister the cost would be $5.50 per visit. This is the Slope.
There is no initial cost so the equation is
y = 5.50x
How many times can they go for $38.50
$38.50 = 5.50x solve for x
x = 7 visits for Maria and her sister. They should have gone with plan A. They would have been able to go to the museum one more time and each saved a quarter.
A closed container has 3.06 ⋅ 1023 atoms of a gas. Each atom of the gas weighs 1.67 ⋅ 10–24 grams. Which of the following shows and explains the approximate total mass, in grams, of all the atoms of the gas in the container?
A. 0.47 grams, because (3.06 + 1.67) ⋅ (1023 ⋅ 10–24) = 4.73 ⋅ 10–1
B.0.51 grams, because (3.06 ⋅ 1.67) ⋅(1023 ⋅ 10–24) = 5.1102 ⋅ 10–1
C.4.73 grams, because (3.06 + 1.67) ⋅ (1023 ⋅ 10–24) = 4.73
D.5.11 grams, because (3.06 ⋅ 1.67) ⋅ (1023 ⋅ 10–24) = 5.1102
Answer:
Step-by-step explanation:
The correct answer is not the first answer, but the second answer in the middle. The third answer is the correct one because, since it has the correct exponent, that is, 0.51 grams.
_________________________________________________________
The approximate total mass is the number of atoms multiplied by the weight of an atom.
The approximate overall mass=3.06 10²³ atoms. (1.67 10⁻²⁴ grams/1 atom) which is equivalent to a mass of 0.51 grams. (1.67 10⁻²⁴ grams/1 atom) = 0.51102 g ≈ 0.51 g
Answer: B. 0.51 grams, because (3.06 ⋅ 1.67) ⋅(1023 ⋅ 10–24) = 5.1102 ⋅ 10–1
Answer:
long story short, the answer is B, 0.51 grams, because (3.06 ⋅ 1.67) ⋅(1023 ⋅ 10-24) = 5.1102 ⋅ 10-1

Answer:
Jamie will need 6 cups of milk.
Step-by-step explanation:
Given that:
A recipe calls for 2 cups of milk for each batch of pancakes.
1 batch of pancakes = 2 cups of milk
As Jamie is going to triple her recipe, thus the amount of milk in the recipe will also be tripled.
3 batches of pancakes = 2*3 cups of milk
3 batches = 6 cups of milk
Hence,
Jamie will need 6 cups of milk.

Solve 4(t+1)= 6(g-4)
Answer:
Step-by-step explanation:
Simplifying
4(t + 1) = 6(g + -4)
Reorder the terms:
4(1 + t) = 6(g + -4)
(1 * 4 + t * 4) = 6(g + -4)
(4 + 4t) = 6(g + -4)
Reorder the terms:
4 + 4t = 6(-4 + g)
4 + 4t = (-4 * 6 + g * 6)
4 + 4t = (-24 + 6g)
Solving
4 + 4t = -24 + 6g
Solving for variable 't'.
Move all terms containing t to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + -4 + 4t = -24 + -4 + 6g
Combine like terms: 4 + -4 = 0
0 + 4t = -24 + -4 + 6g
4t = -24 + -4 + 6g
Combine like terms: -24 + -4 = -28
4t = -28 + 6g
Divide each side by '4'.
t = -7 + 1.5g
Simplifying
t = -7 + 1.5g

Can someone please help me with this question!
Answer:
see explanation
Step-by-step explanation:
For the relationship to be a function then each value of x must map to exactly one unique value of y.
This is true for the points except Z andT, where
x → 3 (Z) and x → 5 (T)
This means the relation is not a function

Which equation represents the line that has a slope 5 and passes through the point (0,-2)
A. y = 5x - 2
B. y = x-3
C. y = 5x
D. y = -2x - 5
Answer:
A
Step-by-step explanation:
because the -2 is where the point is and the slope will start there so when you draw a line the line will pass by (0,-2)

see in the picture, u can see that this parallelogram has a right angle and two adjacent equal edges.
=> this parallelogram is a square
=> the diagonal lines of the parallelogram are perpendicular to each other
=> m∠1 = 90°
⇔ 3y - 6 = 90
⇔ 3y = 96
⇔ y = 32
because this is a square
=> 3x = 18z = 45°
=> x = 15
z = 2.5
