b. four fifths plus two fourths
Step-by-step explanation: Change the fractions to their equivalents in 20ths-- like finding the common denominator.
Divide the original denominator into 20, then multiply the result by the original numerator to get the new numerator.
4/5 20/5 = 4 4×4 = 16 so 4/5 is equivalent to 16/20
2/4 20/4 = 5 5×2 = 10 so 2/4 is equivalent to 10/20
Add: 16/20 + 10/20 = 26/20

What is the cost of 4 pounds of apples, if 3 pounds of apples cost $5.28 and the unit price for each pound of apples is the same?
HELP ASAP!
Answer:
$7.04
Step-by-step explanation:
We use proportions so if 3/$5.28 = 4/x. X being the price of 4 pounds. X works out to 7.039 with the 9 infinitely repeating. We round it up for cents and we get $7.04

Find the area of the grey pathway
52 square metres
Step-by-step explanation:
we can divide the pathway in to 2 parts to find the area
1st part
length = 12m
breadth = 2m
[tex]area = 12 \times 2 = {24}^{2}m [/tex]
2nd part
length = 16-2 = 14
breadth = 2
area =
[tex]area = 14 \times 2 = {28}^{2} m[/tex]
atlast add both areas
52 square metres
Answer:
52m²Step-by-step explanation:
find the area of the horizontal rectangle, add it to the vertical rectangle and remove the common part
2 * 16 + 2 * 12 - 2 * 2 =
52m²

Step-by-step explanation:
Givens:
ParallelogramQR || TSQT || RSQS ≅ SQWith that information, we can figure out the rest.
∠RQS≅∠TSQ and ∠QSR≅∠SQT --- these are alternate interior angles, on opposite sides of the transversal QS while between parallel lines
Finally, ΔQST≅SQR because of ASA.

Point J(-3, -7) was rotated to J'(7, -3). How
many degrees was the rotation?
Answer:
90 clockwise
Step-by-step explanation:
Answer:
270 degrees
Step-by-step explanation:
If both numbers are negative it means its in the lower left quadrant, so to reach 7 and -3, that means we need to reach the lower right quadrant so a 270 degree turn works

d) A patient is given 11÷2ml of medicine three times a day. How long does a bottle of 132 ml of medicine last?
Answer: 8 days.
Explanation;
11/2 = 5.5
5.5 x 3 = 16.5
132/16.5 = 8
Answer:
8 days
Step-by-step explanation:
So, 11/2 * 3 = (33/2) = 16.5 ml
Let the number of days medicine last be 'x'.
⇒ 16.5 * x = 132
⇒ x = 132/16.5
⇒ x = 8.
Therefore, Medicines last for 8 days.
Hope it helps!

MATHEMATICS Proportion Х Y Z 145) If line XY is 24in, lines XY:YZ = 1:2. What is the length of line YZ? A) 12 in B) 24in C) 48in D) 72 in 147) If line YZ is 9ft, lines XY:YZ= 2:3. What is the length of line XY? A) 3ft B) 6ft C) 9ft D) 12ft 148) If line YZ is 1ft, line XY:YZ = 1:4. What is the length of line XY? A) 3in B) 27in C) 2ft D) 18in
Answer:
145. YZ = 48 in
147. XY = 6 ft
148: XY = 3 in
Step-by-step explanation:
In each case, multiply the given proportion by a value that makes it match the given information about the segments.
145)XY is 24in, lines XY:YZ = 1:2. What is the length of line YZ?
Multiply the proportion by 24 in:
XY : YZ = (24 in)(1) : (24 in)(2) = 24 in : 48 in
YZ = 48 in . . . (C)
__
147)YZ is 9ft, lines XY:YZ= 2:3. What is the length of line XY?
Multiply the proportion by 3 ft:
XY : YZ = (3 ft)(2) : (3 ft)(3) = 6 ft : 9 ft
XY = 6 ft . . . (B)
__
148)YZ is 1ft, line XY:YZ = 1:4. What is the length of line XY?
Multiply the proportion by 3 in:
XY : YZ = (3 in)(1) : (3 in)(4) = 3 in : 12 in = 3 in : 1 ft
XY = 3 in . . . (A)
You accelerate from 5m/s to 60m/s in 11 seconds what is the average acceleration.
Change in acceleration: 60 - 5 = 55 m/s
Average acceleration = 55 m/s / 11 second = 5 meters per second squared ( m/s^2)
Answer: 5 m/s^2
Write an equation for the line with a slope 3 and Y intercept -2
A. y=-3x -2
B. y= 1/3 x -2
C. y= 3x - 2
with explanation pls
Answer:
C. y=3x-2
Step-by-step explanation:
Well we know the equation: y=mx+b
The slope is m, so m= 3
And the y-intercept is b, so b= (0,-2) or b=-2
Then,
Subsitute everything in:
y= 3x -2

Hasan plans to choose a book from a section of the store where everything is 25%
off He writes the expression d 0.25d to find the sale price of the book if the original
price is d dollars.
Bella correctly writes another
expression. 0.75d, that will also find the sale price of the
book if the original price is
I/ dollars,
Use the drop-down menus to explain what each part of Hasan's and Bella's
expressions mean.
Hasan's Expression: d - 0.25d
d: Original price0.25: percent discount 0.25d: amount of discountd - 0.25d: sale price--------------------
Bella's Expression: 0.75d
0.75: percent of original priced: original price0.75d: sale price=============================================
Explanation:
The variable d stands for the original price. The store is offering a 25% sale, which means that Hasan will save 25% of the original price. This means 0.25d represents the amount he saves (aka the discount amount).
For instance, let's say d = 100 is the original price. 25% of this is 0.25d = 25 dollars. So if the book is originally $100, then he saves $25.
As you can probably guess, the 0.75 comes from 1 - 0.25 = 0.75; it indicates that if Hasan saves 25%, then he still has to pay the remaining 75%
Notice how d - 0.25d = 1d - 0.25d = (1-0.25)d = 0.75d which points to the sale price being 75% of the original price d.

There are a total of 66 people attending a carnival. The ratio of adults to children is 4 to 7. How many adults are attending the carnival? Enter your answer in the box. adults
Answer:
24 adults
Step-by-step explanation:
The equation to represent the scenario is
4x + 7x = 66
Combine like terms
11x = 66
Isolate x
x = 6
To find the amount of adults attending the carnival, substitute 6 with x.
6*4 = 24 adults
7*4 = 42 children
24 + 42 = 66 people in total

9514 1404 393
Explanation:
Put the given value of x into the expression and evaluate it.
x, 10(x +6), y = 10x +60
2, 10(2 +6), y = 10(8) = 80
4, 10(4 +6), y = 10(10) = 100
6, 10(6 +6), y = 10(12) = 120
8, 10(8 +6), y = 10(14) = 140
