Steffi is painting her house. She has calculated she needs 40 litres of paint in total. She has decided to mix pink paint. She will need 3 litres of white for every litres of red. How many litres of each colour will she need to buy?
Answer:
Red=10 Pink=30
Step-by-step explanation:
you said for every litres of red; therefore, you need 3 litres of pink paint. So the steps are like this 3+1(P+R) ........... you need 30 litres pink and 10 litres red

3 (x − 2) = 2x + 7
Answer:
Distribute the 3 on the left hand side
Step-by-step explanation:
3 (x − 2) = 2x + 7
Distribute the 3 on the left hand side
3x -6 = 2x +7
Then subtract 2x from each side
A complex electronic system is built with a certain number of backup components in its subsystems. One subsystem has four identical components, each with a probability of .2 of failing in less than 1000 hours. The subsystem will operate if any two of the four components are operating. Assume that the components operate independently. Find the probability that a exactly two of the four components last longer than 1000 hours. b the subsystem operates longer than 1000 hours.
Answer:
a. 0.1536
b. 0.9728
Step-by-step explanation:
The probability that a component fails, P(Y) = 0.2
The number of components in the system = 4
The number of components required for the subsystem to operate = 2
a. By binomial theorem, we have;
The probability that exactly 2 last longer than 1,000 hours, P(Y = 2) is given as follows;
P(Y = 2) = [tex]\dbinom{4}{2}[/tex] × 0.2² × 0.8² = 0.1536
The probability that exactly 2 last longer than 1,000 hours, P(Y = 2) = 0.1536
b. The probability that the system last longer than 1,000 hours, P(O) = The probability that no component fails + The probability that only one component fails + The probability that two component fails leaving two working
Therefore, we have;
P(O) = P(Y = 0) + P(Y = 1) + P(Y = 2)
P(Y = 0) = [tex]\dbinom{4}{0}[/tex] × 0.2⁰ × 0.8⁴ = 0.4096
P(Y = 1) = [tex]\dbinom{4}{1}[/tex] × 0.2¹ × 0.8³ = 0.4096
P(Y = 2) = [tex]\dbinom{4}{2}[/tex] × 0.2² × 0.8² = 0.1536
∴ P(O) = 0.4096 + 0.4096 + 0.1536 = 0.9728
The probability that the subsystem operates longer than 1,000 hours = 0.9728

Luke is driving from his house to the store. After driving 16 miles at a constant speed of 0.8 mile/minute, he realizes that he forgot his wallet. So,
he turns around and drives all the way back to his house at the same speed. The equation below models Luke's distance, in miles, from home as
he drives for t minutes.
d = -0.8t - 20 + 16
Using the given equation, match the number of minutes since Luke started driving from his house to his distance from the house.
12 minutes
27 minutes
31 minutes
7 minutes
10.4 miles on his return trip
5.6 miles on his trip to the restaurant
9.6 miles his trip to the restaurant
7.2 miles on his return trip
Answer:
10.4 miles on his return trip → 27 minutes
5.6 miles on his trip to the restaurant → 7 minutes
9.6 miles on his trip to the restaurant → 12 minutes
7.2 miles on his return trip → 31 minutes
Step-by-step explanation:
When solving, we note that on his trip to the restaurant, [tex]\left |t - 20 \right |[/tex] is a negative number, while it is a positive number on his return trip
1) At 10.4 miles on his return trip, we have;
[tex]d = 10.4 = -0.8 \cdot \left |t - 20 \right |+ 16[/tex]
Therefore;
(10.4 - 16)/(-0.8) = 7 = [tex]\left |t - 20 \right |[/tex]
t = 20 + 7 = 27
The number of minutes since Luke started driving from his house, t = 27 minutes
2) At 5.6 miles on his trip to the restaurant, we have;
[tex]d = 5.6 = -0.8 \cdot \left |t - 20 \right |+ 16[/tex]
Therefore;
(5.6 - 16)/(-0.8) = 13 = [tex]\left |t - 20 \right |[/tex]
Here, t is less than 20 (minutes), therefore, t - 20 is negative, we get
t - 20 = -13
∴ t = 20+ (-13) = 7
The number of minutes since Luke started driving from his house when he is 5.6 miles on his trip to the restaurant, t = 7 minutes
3) At 9.6 miles on his trip to the restaurant, we have;
[tex]d = 9.6 = -0.8 \cdot \left |t - 20 \right |+ 16[/tex]
Therefore;
(9.6 - 16)/(-0.8) = 8 = [tex]\left |t - 20 \right |[/tex]
[tex]\left |t - 20 \right |[/tex] is negative on his trip to the restaurant, therefore;
- [tex]\left |t - 20 \right |[/tex] = 8
t - 20 = -8
t = 20 - 8 = 12
The number of minutes since he started driving from his house to when he is 9.6 miles on the his trip to the restaurant, t = 12 minutes
4) At 7.2 miles on his return trip, we have;
[tex]d = 7.2 = -0.8 \cdot \left |t - 20 \right |+ 16[/tex]
Therefore;
(7.2 - 16)/(-0.8) = 11 = [tex]\left |t - 20 \right |[/tex]
t = 20 + 11 = 31
At 7.2 miles from his house on the return trip, t = 31 minutes

Which formula gives the coordinates of the midpoint of the segment connecting points (u, v) and (s, 6,t),
Answer:
[tex](\frac{u+s}{2} , \frac{v+t}{2} )[/tex] (the first option)
Step-by-step explanation:
The midpoint of a segment connecting two points [tex](x_1, y_1)[/tex] and [tex](x_2,y_2)[/tex] can be described by the following formula: [tex]\frac{x_1 + x_2}{2} = x_{mid}[/tex] and [tex]\frac{y_1 + y_2}{2} = y_{mid}[/tex]. As you can see, the formula essentially takes the average of the x- and y-coordinates to find the point in the middle.
With points (u, v) and (s, t), the midpoint becomes [tex](\frac{u+s}{2} , \frac{v+t}{2} )[/tex] (the first option).

Answer:
60% did not germinate.
Step-by-step explanation:
100% = 5
how many percent are 2 of of these 5 ?
2 = 2/5 × 5 = 2/5 × 100% = 40%
all the other seeds are then the rest of 100%.
100% - 40% = 60%
=>
60% of the seeds did not germinate.
but 40% did.

The point is (3, -2), where the function reaches its minimum value.
The y-coordinate of this point represents the lowest value of the range of the function.
Here, the y-coordinate is -2.
Thus, the lowest value of the range of the function is -2.

Answer:
12.5%
Step-by-step explanation:
There are 8 equal sized slices
1 slices is yellow
P(yellow) = number of yellow slices/ total number of slices
= 1/8
=.125
= 12.5%
Answer:
12.5%
Step-by-step explanation:
Probability = favorable outcomes / possible outcomes
There are 8 possible outcomes
And 1 favorable outcome ( the 1 yellow portion )
So the probability of the spinner landing on yellow is 1/8 which can also be written as a percentage (12.5%)
On the grid below, draw a right triangle with vertices at E (2,2), F(2,8), and G(10,8). Find the lengths of these three sides. If necessary, round to the nearest tenth
Answer:
The lengths of the sides are 6, 8 and 10.
Step-by-step explanation:
The vertices of a right angles triangle are E (2,2), F (2,8), and G (10,8)
The distance between the two points is
[tex]d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]
So, the lengths of the sides are

.
Answer:
either 0 or 8, see the step by step for rationale pending the actual question
Step-by-step explanation:
two parallel lines will never intersect.
if it is mean to find the number of 90 degree angles of the two parallel lines and the perpendicular lines, the answer would be 8.
if two lines are perpendicular think of a + sign. there are four angles to make 360 degree so each must be 90 (and the definition of perpendicular).
since there are two parallel lines that intersection happens twice. so 8

Determine the area of a regular pentagon that has a perimeter of 22 cm in the apothem of 3 cm
============================================================
Explanation:
Refer to the diagram below. I've split the regular pentagon into 5 equal slices (as if it was a pizza). Each triangle is congruent.
The base of each triangle is 22/5 = 4.4 cm
The height of each triangle is the apothem 3 cm. The apothem stretches from the center to the midpoint of any given side. It's the red dashed line in the diagram.
The area of one of the triangles is base*height/2 = 4.4*3/2 = 6.6 square cm.
Since we have 5 identical triangles with this area, we have a total area of 5*6.6 = 33 square cm
Answer:
165
Step-by-step explanation:
The formula for the area of the pentagon is 5/2 × s × a.
5/2×22×3
5/2 × 66/1= 66÷2
=33
33×5=165
