Answer:
the third one
Step-by-step explanation:
Answer:
[tex]\boxed {\boxed {\sf 2. \ y= -2x+17}}[/tex]
Step-by-step explanation:
We are given a point and a slope, so we can use the point-slope formula.
[tex]y-y_1=m(x-x_1)[/tex]
where m is the slope and (x₁, y₁) is a point the line passes through.
For this problem, the slope is -2 and the point is (5,7). Therefore:
[tex]m= -2 \\x_1= 5\\y_1= 7[/tex]
Substitute the values into the formula.
[tex]y-7= -2(x-5)[/tex]
We want to solve for y, because the standard form of a line is y=mx+b (where m is the slope and b is the y-intercept).
Distribute the -2.
[tex]y-7= (-2*x ) + (-2*-5)[/tex]
[tex]y-7= -2x+10[/tex]
7 is being subtracted from y. The inverse of subtraction is addition, so add 7 to both sides.
[tex]y-7+7=-2x+10+7\\y= -2x+17[/tex]
The equation of the line is y= -2x+17

Answer:
98
Step-by-step explanation:
angles 1 and 2 are congruent, the lines in each side of the shape prove this.
another way to solve if you are not sure is to subtract all of the numbers from 360. all quadrilaterals equal 360 degrees, so if you subtract each of the three angles from 360, you will be left with the last angle.

Pretend the program in Senegal has been reducing infant mortality at a rate 7.3 % per year. How long will it take for infant mortality to be reduced by 33 %
Answer:
Infant mortality will reduce to 33% in 1.63 years
Step-by-step explanation:
Let the population be X
Population after 1 year
[tex]X - 7.3[/tex] % of [tex]X[/tex]
[tex]X -0.073 X\\0.927X[/tex]
As we know
[tex]P = P_0 * e^{rt}[/tex]
Substituting the given values we get -
[tex]\frac{P_0 - 0.33P_0}{P_0} = e^{-0.33 * t}\\0.67 = e^{-0.33 * t}\\[/tex]
Taking log on both sides we get -
[tex]-0.20273 = -0.33 * t\\t = 1.627[/tex]
You can form a general expression for resultant reduction percentage after t years. Then equate it with 33% to get the value of t
The time that will be taken by the program to reduce the infant mortality rate by 33% is approx 3.35 years.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
How to find a general expression for resultant reduction percentage after t years?The rate of decrement for infant mortality rate is 7.3% per year.
Let the mortality rate in the start be [tex]r[/tex]
Then after 1 year it becomes
[tex]r - \dfrac{r}{100} \times 7.5 = r(1-\frac{7.5}{100}) = r_1 \text{\: (say)}[/tex]
After 1 more year, we will have:
[tex]r_1 -> r_1(1 - \frac{7.5}{100}) = r(1-\frac{7.5}{100})(1-\frac{7.5}{100}) = r(1-\frac{7.5}{100}) ^2 = r_2 \text{\: (say)}[/tex]
Thus, after t years, we will have:
[tex]r_t = r(1-\frac{7.5}{100})^t[/tex]
Simplifying it, we get:
[tex]r_t = r(1 - 0.075)^t = r(0.925)^t[/tex]
The percent of decrement can be calculated by:
[tex]p = \dfrac{\text{old rate - new rate}}{\text{old rate}} \times 100[/tex]
Thus,
the percent of decrement after t years will be
[tex]p = \dfrac{r - r_t}{r} \times 100 = \dfrac{r(1- (0.925)^t)}{r} \times 100 = 100(1-0.925^t)\\\\p = 100(1-0.925^t)[/tex]
We need the time after which the infant mortality rate would be reduced by 33%, thus, p = 33%
or
[tex]p = 33\\p = 100(1-0.925^t) = 33\\1 -0.925^t = \dfrac{33}{100}\\t = log_{0.925}(1 - \dfrac{33}{100}) \approx 3.3525[/tex]
Thus, after approx 3.35 years, the mortality rate would decrease by 33%
Thus,
The time that will be taken by the program to reduce the infant mortality rate by 33% is approx 3.35 years.

The ratio of pharmacy technicians on duty at the hospital during for the day vs. night shifts is 32:19. 1. Express as a percentage how many pharmacy technician staff work the night shift. Round your final answer as a percentage rounded to two decimal places. Explain the answer
Answer:
37.38
Step-by-step explanation:
Remark
The ratio tells you how they are divided between night and day.
In other words night/ day = 19/32
That's not what you want.
What you want is night over total.
Total
Total = night + day = 19.1 + 32 = 51.1
Night Percent
Night% = Night * 100 / Total
Night% = 19.1 * 100 / 32
Night% = 37.38 %
Here, we are required to express ratio as a percentage
The percentage of pharmacy technician during the night is 37.25%
pharmacy technician during the day = 32
pharmacy technician during the night = 19
Total ratio = 32 + 19
= 51
percentage of pharmacy technician during the night = pharmacy technician during the night / Total ratio × 100
= [tex] \frac{19}{51} \times 100[/tex]
= 0.3725490196078 × 100
= 37.254901960784%
Approximately
37.25% to two decimal place
This means 37.25% of pharmacy technician work during the night

6x - 8y = 12 and 5x + 8y = -1 Solve using elimination
Answer:
Step-by-step explanation:
6x-8y=12
5x+8y=-1
add them
11x=11
x=1
y=-3/4
Answer:
(1,-3/4)
Step-by-step explanation:
Luckily, y is already opposites, so it should be easier:
6x-8y=12
5x+8y=-1
Combine; This should end up with y eliminated -
11x = 11
x = 1
Now we can plug 1 in for x in one of the equations to find y. I'm going to use the second one.
5(1) +8y = -1
5+8y=-1
8y=-6
y=-6/8 (you can simplify)
The point at which the lines intersect is (1,-3/4)

Step-by-step explanation:
Answer for the first question.
since the triangles are congruent so angles and sides are also congruent I.e. sides and angles are equal then,
3x - 3 = 12
3x = 12 + 3
3x = 15
x = 5
55° = 7x + y
55° = 7 * 5 + y
35° + y = 55°
y = 55° - 35°
y = 20°
Answer for the second question,
x + 70° = 2x - 2° {Exterior angle of a triangle is equal to the sum of two opposite interior angles }
2x - x = 70° + 2°
x = 72°
Now
<WXY = 2x - 2°
= 2 * 72° - 2
= 142 °
Hope it will help :)❤✔

Answer:
[tex]x=4[/tex]
Step-by-step explanation:
By the Triangle Proportionality Theorem:
[tex]\displaystyle \frac{x}{12}=\frac{x+1}{15}[/tex]
By cross-multiplication:
[tex]\displaystyle 12(x+1)=15(x)[/tex]
Distribute:
[tex]12x+12=15x[/tex]
Subtract 12x from both sides:
[tex]12=3x[/tex]
Hence:
[tex]x=4[/tex]
Answer:
4
Step-by-step explanation:
The first thing you should notice is that the triangles (the smaller one and the larger one) are similar due to angle-angle similarity (the top angle equals itself, and because the bases are parallel lines cut by a transversal, the base angle of the bigger triangle is equal to the corresponding base of the smaller triangle.
Similar triangles' corresponding sides have equal ratios to one another. That means we can set up an equation: side of smaller triangle ÷ corresponding side of larger triangle = other side of smaller triangle ÷ corresponding side of larger triangle. We plug the values given to us and can change this equation to:[tex]\frac{x}{x + 12} = \frac{x + 1}{x + 16}[/tex] **
We now multiply both sides of the above equation by [tex](x + 12)(x + 16)[/tex] to get: [tex]x(x + 16) = (x + 1)(x + 12)[/tex]
[tex]x^{2} + 16x = x^{2} + 13x + 12[/tex]
[tex]3x = 12[/tex]
[tex]x = 4[/tex]
That means our answer, for the value of x, is 4
** Make sure you don't say [tex]\frac{x}{12} = \frac{x + 1}{15}[/tex], because those aren't the sides of the larger square.
