Answer: 61
Step-by-step explanation: 1+12*5
Simplify the sum 43+(96/8)*5-42
1
Add 43 and -42
12*5
Reduce 96/8 by factoring out and cancelling common factors
8*12/8.1
Factor out 8 from the top and bottom of the fraction
8*12=96
8*1=8
96/8=12
multiply 12 and 5. 12*5= 60
add 60 and 1
so the answer is 61

The measures of the angles of an isosceles triangle are in the ratio
3:3:2. Find the measure of the largest angle.
answer:
67.5
Explanation:
Let the triangle be ΔABC and angles be ∠A,∠B,∠C
Now, we know that all the 3 angles of a triangle sum up to be 180° from the Triangle Sum Property.
:.∠A + ∠B + ∠C = 180
:.3x+3x+2x=180 [3:3:2]
:.8x = 180
:.x = 180/8
:.x = 22.5°
:.
/_A=3x=3(22.5)=67.5°
/_B=3x=3(22.5)=67.5°
/_C=2x=2(22.5)=45°

The table shows the distance Penelope is from the park as she walks to soccer practice. Assume the relationship between the two quantities is linear. Find and interpret the rate of change and initial value. Then write the equation of the function in the form y=mx+b
-- help me
The equation of the function in the form y=mx+b is y = 110x-2020
Rate of a change of functionThe standard equation of a line is expressed as:
y = mx + b
where:
m is the rate of change or slope
b is the intecept
Using the coordinate points
Determine the slope
m = 550/5
m = 110
For the intercept
280 + 110(20) + b
280 = 2200 + b
b = 180 - 2200
b = -2020
Hence the equation of the function in the form y=mx+b is y = 110x-2020

Students were asked to choose the city they would most like to visit and 5/10 chose either New York or Los Angeles. If 2/10 of the students chose Los Angeles, what fraction chose New York?
Answer:
3/10
Step-by-step explanation:
There are 10 students
5 of them voted either Los Angeles or New York
That means ignore (screw) the other 5 people
If 2/10 students chose Los Angeles,
that is 2/5 because the others didn't choose those cities that are part of the equation (nobody asked about the other people)
So if 5 people chose two groups of cities, and two people chose one city, that meant 3 chose the other
3/10 (remember its out of all of them) Students Voted for New York
Hope this helps :)

Answer:
i) Using log law: [tex]\log_aa=1[/tex]
[tex]\implies \log_55+1=1+1=2[/tex]
ii) [tex]\log \left(\dfrac{15}{8}\right)+4 \log 2-\log 3[/tex]
Using log law [tex]a \log b=\log b^a[/tex]:
[tex]\implies \log \left(\dfrac{15}{8}\right)+\log 2^4-\log 3[/tex]
[tex]\implies \log \left(\dfrac{15}{8}\right)+\log 16-\log 3[/tex]
Using log law [tex]\log a-\log b=\log (\frac{a}{b})[/tex]:
[tex]\implies \log \left(\dfrac{15}{8}\right)+\log\left(\dfrac{16}{3}\right)[/tex]
Using log law [tex]\log a+\log b=\log(ab)[/tex]:
[tex]\implies \log \left(\dfrac{15}{8}\cdot \dfrac{16}{3}\right)[/tex]
[tex]\implies \log 10[/tex]
Using log law: [tex]\log_aa=1[/tex]
[tex]\implies \log_{10} 10=1[/tex]
iii) Take log of base 10:
[tex]\log_{10}(\sqrt{8.357}\times0.895^2)[/tex]
[tex]\implies \dfrac12\log_{10}(8.357)+2\log_{10}(0.895)[/tex]
Log tables
The characteristic of the logarithm of a number is the exponent of 10 in its scientific notation.
The mantissa is found using the log tables and is always prefixed by a decimal point.
The row is the first two non-zero digits of the number, and the column is the 3rd digit of the number
Use the log tables to find [tex]\log_{10}(8.357)[/tex]:
8.357 = 8.357 × 10⁰
⇒ characteristic = 0
log table: row 83, column 5 ⇒ mantissa 9217
(as there is a 4th digit) Mean difference 7 = 4
mantissa + mean difference = 9217 + 4 = 9221 ⇒ 0.9221
characteristic + mantissa = 0 + 0.9221 = 0.9221
Therefore, [tex]\log_{10}(8.357)=0.9221[/tex]
Use the log tables to find [tex]\log_{10}(0.895)[/tex]:
[tex]0.895 = 8.95\times 10^{-1}[/tex]
⇒ characteristic = -1
log table: row 89, column 5 ⇒ mantissa 9518⇒ 0.9518
characteristic + mantissa = -1 + 0.9518= -0.0482
Therefore, [tex]\log_{10}(0.895)=-0.0482[/tex]
Therefore,
[tex]\implies \dfrac12\log_{10}(8.357)+2\log_{10}(0.895)[/tex]
[tex]\implies \dfrac12 \cdot 0.9221+2\cdot-0.0482[/tex]
[tex]\implies 0.36465[/tex]
Therefore,
[tex]\log_{10}(\sqrt{8.357}\times0.895^2)=0.36465[/tex]
Using [tex]\log_ab=c \implies a^c=b[/tex]
[tex]\implies \sqrt{8.357}\times0.895^2=10^{0.36465}[/tex]
[tex]\implies \sqrt{8.357}\times0.895^2=2.3155[/tex]

What is this measurement in yards and feet?
The measurement is yd ft.
Answer:
There are 3 feet in a yard, so divide 34 by 3, which is 11 with a remainder of 1, the remainder 1 is the remaining foot, so 34 feet is 11 yards and 1 foot.
Step-by-step explanation:
A researcher decides to determine if the type of writing utensil that a student uses while doing their math affects their accuracy. A group of 1200 high school students in Algebra are randomly divided into four groups. One group uses a regular pencil, another uses a mechanical pencil, one group uses a pen and the fourth group is allowed to use whatever type of utensil they feel like. A math test is given and the results are tabulated for accuracy. The variable- type of writing utensil - is what type of variable?
Since the variable type of writing utensil assumes labels and not numbers, it is classified as qualitative.
What are qualitative and quantitative variables?Qualitative variables: Assumes labels or ranks.Quantitative variables: Assume numerical values.In this problem, the type of writing utensil has 4 labels: regular pencil, mechanical pencil, pen, whatever.
Hence, since the variable assumes labels and not numbers, it is classified as qualitative.

M/8 plus 2/3 equals 7/3
Write the equation of the line that passes through the points (7, –4) and (–1, 3), first in point-slope form, and then in slope-intercept form.
Answer:
y +4 = -7/8(x -7)y = -7/8x +17/8Step-by-step explanation:
Given two points, the equation for the line can be found by starting with determining the slope. Then the point-slope form can be used to find the equation. That form can be rearranged to give the slope-intercept form (or any other form you may desire.)
The slope formula is ...
m = (y2 -y1)/(x2 -x1)
m = (3 -(-4))/(-1 -7) = 7/-8 = -7/8
Then the point-slope form using the first point is ...
y -k = m(x -h) . . . . line with slope m through point (h, k)
y +4 = -7/8(x -7) . . . . . line with slope -7/8 through (7, -4)
__
Eliminating parentheses, and subtracting 4 gives the slope-intercept equation:
y +4 = -7/8x +49/8 . . . eliminate parentheses
y = -7/8x +17/8 . . . . . subtract 4; slope-intercept equation

How would I solve this problem?
The area of the garden enclosed by the fencing is
A(x, y) = xy
and is constrained by its perimeter,
P = x + 2y = 200
Solve for x in the constraint equation:
x = 200 - 2y
Substitute this into the area function to get a function of one variable:
A(200 - 2y, y) = A(y) = 200y - 2y²
Differentiate A with respect to y :
dA/dy = 200 - 4y
Find the critical points of A :
200 - 4y = 0 ⇒ 4y = 200 ⇒ y = 50
Compute the second derivative of A:
d²A/dy² = -4 < 0
Since the second derivative is always negative, the critical point is a local maximum.
If y = 50, then x = 200 - 2•50 = 100. So the farmer can maximize the garden area by building a (100 ft) × (50 ft) fence.
