Answer:
B: 96%
Step-by-step explanation:
Since 7 out of 100 is 7% (7÷100=0.07)
then 7÷183=0.038 or 0.04. So 4% of the days she was absent. 100%-4% is 96% so holly was in attendance for 96% of the days.

marcia is typing her report for history class. She can type 4 pages in 45 minutes. At that rate, how many pages does she type per hour? Round to the nearest hundredth.
Answer:
5.34 pages/h
Step-by-step explanation:
4/45 = p/60
p ≈ 5.34
Answer:
Step-by-step explanation:
3/4 of an hour is the same as 0.75
Write a proportion.
4 (pages)/0.75 (hours)=p(pages)/1 hour
Cross multiply and divide
(4x1)÷0.75=5.33 (rounded to the nearest hundred)
p=5.33
Marcia can type 5.33 pages per hour.

What’s the equation of the line in fully simplified slope-intercept form
Answer:
y= -x - 8
Step-by-step explanation:
To write an equation in slope-intercept form, we naturally need both the slope and the y-intercept. Here, our y-intercept is -8, and our slope is -1. The general form of a line in slope intercept form is y = mx + b, where m is the slope and b is the y intercept. Using our values of m = -1 and b = -8 then gives us the equation y = -x - 8.

Math!!!! Fined the area of the triangle
Answer:
Area = 40 cm²
Step-by-step explanation:
Area of triangle is derived by the formula,
Area = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
Length of Base = 8 cm
Height of the triangle = 10 cm
Therefore, area of the given triangle = [tex]\frac{1}{2}(8)(10)[/tex]
= 40 cm²

t a school. number of boys/number if girls =9/7. there are 116 more boys than girls. work out the total number of students at the school
Answer:
928
Step-by-step explanation:
Ratio of boys to girls is 9:7, so boys are 9/(9+7) = 9/16 of the total, and the girls are 7/16
the difference is 9/16-7/16 = 2/16 = 1/8, so
x * 1/8 = 116
x = 116*8 = 928

Zack and Dave each bought some coins from jerry online. Dave bought 5 more coins than Zack bought
C. Explain why it’s not necessary to know how many coins Zack bought to determine how much more Dave paid than Zack paid
Answer & Step-by-step explanation:
number of Dave's coins = number of Zack's coins + 5
The question is asking to find the difference in prices paid (thus "more"), completely unrelated to the number of coins Zack bought as these two numbers are independent of one another. The difference in price can be found by simply multiplying the cost of one coin by 5.

Round to nearest tenth
Answer:
Step-by-step explanation:
this is exactly the same as the 1st one, just they put it in a different orientation. sooo use law of cosines , where
QR = c
a = 12
b = 23
cos(120) = cos (P)
c = sq rt [ a^2+b^2﹣2*a*b*cos(P) ]
QR = sq rt [ 12^2 + 23^2 - 2* 12*23*cos(120) ]
QR = sq rt [ 144 + 529 - 552 * (-0.5 0 ]
QR = sq rt [ 673 + 276 ]
QR = sq rt [ 949 ]
QR = 30.8058
rounded to nearest 10th is
QR = 30.8 :)

If 2x - 3y = 24 and 3x + 4y = 2, what is the value of x - y?
Answer:
2x-3x=24____eqn 1
3x+4y=2____eqn 2
solve eqn 1 and 2 simultaneously using elimination method
eliminate x use the coefficients of x in the two equations to multiply each other i.e
3(2x-3y=24)
2(3x+4y=2)
6x-9y=72
6x+8y=4
eliminate x using the subtraction sign(-)
6x-6x-9y-(+8y)=72-4
-9y-8y=68
-17y=68
divide both side by the coefficient of y
y=68/-17
y=-4
put y=-4 in eqn 2
3x+4y=2
3x+4(-4)=2
3x-16=2
collect like term
3x=2+16
3x=18
divide both side by the coefficient of x
x=18/3
x=6
since we're asked to find x-y
6-(-4)
6+4=10
) A coin collection consisting of pennies, dimes, and quarters totals 45 coins. The number of
quarters is five more than twice the number of pennies and the number of dimes is four
more than the number of pennies. How much is the coin collection worth?/
9514 1404 393
Answer:
$7.14
Step-by-step explanation:
Let p, d, q represent the numbers of pennies, dimes, and quarters in the collection, respectively.
p + d + q = 45 . . . . . . . . there are 45 coins in the collection
2p +5 = q . . . . . . . . . . . . 5 more than twice the number of pennies
p + 4 = d . . . . . . . . . . . . . 4 more than the number of pennies
Substituting the last two equations into the first gives ...
p +(p +4) +(2p +5) = 45
4p = 36 . . . . . . . . . . . . . subtract 9
p = 9 . . . . . . . . . . . divide by 4
d = 9 +4 = 13
q = 2(9) +5 = 23
The value of the collection is ...
23(0.25) +13(0.10) +9(0.01) = 5.75 +1.30 +0.09 = 7.14
The coin collection is worth $7.14.
