WILL GIVE BRAINIEST TO THE RIGHY ANSWER NEED HELP ASAP check the picture
Answer:
21 units
Step-by-step explanation:
[tex] \triangle ABC\sim \triangle DEF... (given) [/tex]
[tex]\huge \therefore \frac{AB}{DE} =\frac{BC}{EF}.. (csst) [/tex]
[tex] \huge \therefore \frac{8.4}{x} =\frac{10}{25} [/tex]
[tex] \huge \therefore x=\frac{25\times 8.4}{10} [/tex]
[tex] \huge \therefore x=\frac{210}{10} [/tex]
[tex]\huge \therefore x=21 [/tex]
Hence, length of DE = 21 units

A drawer contains 8 red socks, 6
white socks, and 4 blue socks. Without
looking, you draw out a sock, return
it and draw out a second sock. What is
the probability that the first sock is
white and the second sock is blue?.
simplest form
Answer:
2/27
Step-by-step explanation:
First probability = 6/18 = 1/3
second probability = 4/18 = 2/9 (in this case the number of socks remains the same because we returned the first one)
Final probability = 1/3 * 2/9 = 2/27

The vertex of PMQ is 2.
The sides of angle 2 are PM and QM, since they both connect to form angel 2.
Two other names for angle one are NMQ and QMN since the middle letter of each sequence is representing angel 1.
I hope this makes sense when looking at the figure.

I’m so stumped..
The image of the given point under the given translation is (0, 3)
How to find the image of the given point under the given translation?Translation can be defined as movement in a straight line. Translated shapes or images have the same size as the original shape
Given: P(-5, 7) T(x, y) = (x + 5, y - 4)
In order to find the image of P (P'), Use:
P' = P + T
P' = (-5, 7) + (5, -4) [ Note: T(x, y) = (x + 5, y - 4) ]
P' = (-5+5, 7+(-4))
P' = (0, 3)
Therefore, the image of the given point is (0, 3). The number that belongs in the green box is 0

Answer:
13) 25 and 17
14) cupcakes = $5
brownies = $3
Step-by-step explanation:
13) you can set this up as equations
so x + y = 42
x-y = 8
solve simultaneously by subtracting from each other
2y = 34
y= 17
if y = 17
42 - 17 = 25 = x

A salesman normally makes a sale (closes) on % of his presentations. Assuming the presentations are independent, find the probability of the following. a) He fails to close for the first time on his attempt. b) He closes his first presentation on his attempt. c) The first presentation he closes will be on his second attempt. d) The first presentation he closes will be on one of his first three attempts.
Answer:
[tex](a)\ 0.0864[/tex]
[tex](b)\ 0.096[/tex]
[tex](c)\ 0.24[/tex]
[tex](d)\ 0.936[/tex]
Step-by-step explanation:
Given
[tex]p \to[/tex] close
[tex]q \to[/tex] fail to close
[tex]p = 60\%[/tex]
[tex]p = 0.60[/tex]
First, calculate the value of q
Using complement rule
[tex]q = 1 - p[/tex]
[tex]q = 1 - 0.60[/tex]
[tex]q = 0.40[/tex]
So, we have:
[tex]p = 0.60[/tex] and [tex]q = 0.40[/tex]
Solving (a): Fails to close on the 4th attempt
This means that he closes the first three attempts. The event is represented as: p p p q
So, we have:
[tex]Pr = p*p*p*q[/tex]
[tex]Pr = p^3*q[/tex]
[tex]Pr = 0.60^3*0.40[/tex]
[tex]Pr = 0.0864[/tex]
Solving (b): He closes for the first time on the 3rd attempt
This means that he fails to close the first two attempts. The event is represented as: q q p
So, we have:
[tex]Pr = q * q * p[/tex]
[tex]Pr = q^2 * p[/tex]
[tex]Pr = 0.40^2 * 0.60[/tex]
[tex]Pr = 0.096[/tex]
Solving (c): First he closes is his 2nd attempt
This means that he fails to close the first. The event is represented as: q p
So, we have:
[tex]Pr = q * p[/tex]
[tex]Pr = 0.40 * 0.60[/tex]
[tex]Pr = 0.24[/tex]
Solving (d): The first he close is one of his 3 attempts
To do this, we make use of complement rule
The event that he does not close any of his first three attempts is: q q q
The probability is:
[tex]Pr = q*q*q[/tex]
[tex]Pr = q^3[/tex]
The opposite is that the first he closes is one of the first three
So, we have:
[tex]Pr' = 1- Pr[/tex] --- complement rule
[tex]Pr' = 1- q^3[/tex]
[tex]Pr' = 1- 0.40^3[/tex]
[tex]Pr' = 1- 0.064[/tex]
[tex]Pr' = 0.936[/tex]
If t is time in hours, what does this function represent?
f(t) = 2.0.3^t
A. a 30-percent increase every hour
B. a 30-percent decrease every hour
C. a 70-percent decrease every hour
D. a 100-percent increase every hour
Answer:
C. a 70-percent decrease every hourStep-by-step explanation:
Given function:
f(t) = 2.0*(0.3)^tThis is exponential decay because:
0.3 = 1 - 0.7 = 100% - 70%and it represents 70% decrease every hour (if it is time in hours)
Correct choice is C

A straight has slope equals to ½ and y-intercept equals to -5. What’s the equation for this straight line?
Answer:
y = ½x - 5
Step-by-step explanation:
Given the following data;
Slope, m = ½
Intercept, c = -5
To write the equation of straight line;
Equation of straight line is y = mx + c
Where;
m is the slope.
x and y are the points
c is the intercept.
Substituting the values into the formula, we have;
y = ½x + (-5)
y = ½x - 5
[tex] y = \frac {1}{2}x - 5 [/tex]
