Matthew is training to participate in a half marathon. The table below shows the number of miles he runs in weeks 1 and 2. Week Number of Miles Run 1 12.5 2 13.5 Each week, Matthew increases the number of miles he runs in the previous week by the same percent. How many miles does Matthew run in week 3? Do not round your answer

Answer:

14.58 miles.

Step-by-step explanation:

Matthew is training to participate in a half marathon.

The distance covered by Matthew on the first day is 12.5 miles.

The distance covered by Matthew on the second day is 13.5 miles.

The distance increased on the second day is, 13.5-12.5=1 mile.

The percentage will be,

=\dfrac{1}{12.5}\times 100\%

=0.08\times 100\%

=8\%

Hence, each day he runs 8% more. So the distance covered by him on day 3 will be,

=13.5+\left(13.5\times \dfrac{8}{100}\right)

=13.5+1.08

=14.58 miles

One pound of grapes costs $1.55. Which equation correctly shows a pair of equivalent ratios that can be used to find the cost of 3.5 pounds of grapes?

Answer:

Given the statement: One pound of grapes costs $1.55.

Let x be be the cost of 3.5 pounds of grapes.

Equivalent ratios states that the  two ratios that express the same relationship between numbers.

Therefore, by equivalent ratio:

\frac{1 pound}{cost of 1 grapes} =\frac{3.5 pound}{cost of 3.5 grapes}

then, we have;

\frac{1}{1.55}=\frac{3.5}{x}

Cross multiply the above equation; we hve

x = 1.55 \times 3.5

x = 5.425

therefore, the cost of 3.5 pounds of grapes is, $5.425

QUESTION POSTED AT 22/02/2020 - 06:10 PM

The figure shows five polygons: ABCDE, FGHIJ, KLMNO, PQRST, and UVWXY. Polygon_____ cannot be mapped onto the others by similarity transformations.

Answer: The answer is polygons ABCDE and PQRST cannot be mapped.

Step-by-step explanation:  We are given a figure with five different polygons. We are to select two polygons that cannot be mapped to each other by similarity transformations.

Two polygons are said to be similar of their corresponding sides are proportional.

In polygons ABCDE and PQRST, we have  

AB = 10 units, BC = 8 units, CD = 6 units, PQ = 6 units, QR = 5 units and PT = 3 units.

We have

\dfrac{AB}{QR}=\dfrac{10}{5}=2,\\\\\dfrac{BC}{PQ}=\dfrac{8}{6}=\dfrac{4}{3}.

Therefore, the ratio of the corresponding sides are not proportional/. Hence the two polygons cannot be similar.

Thus, polygons ABCDE and PQRST cannot be mapped to each other by similarity transformations.

Side ST = 5, side US = 8, side VW = 5, and side XV = 8. What side corresponds to side TU and can be used to show that ΔSTU ≅ ΔVWX by SSS? (Enter your answer using letters only)

Answer: WX


Step-by-step explanation:

Given: In ΔSTU and ΔVWX

side ST = 5, side US = 8, side VW = 5, and side XV = 8.

Thus side ST=side VW=5 [first two letter of the name]

and side US=side XV=8 [last and first letter of the name]

To prove ΔSTU ≅ ΔVWX by SSS congruency postulate, we have two pairs of equal sides.

The third pair must be TU=WX [last two letters of the name]

Subtract 1/4w+4 from 1/2w+3 . −1/4w+1 1/4w−1 −1/4w+7 1/4w+7 (the 1/4 's and 1/2 are fractions)

Answer:  Second option is correct.

Step-by-step explanation:

Since we have given that

Subtract \frac{1}{4}w+4 from \frac{1}{2}w+3

So, we will simplify it using subtraction:

\frac{1}{2}w+3-(\frac{1}{4}w+4)\\\\=\frac{1}{2}w-\frac{1}{4}w+3-4\\\\=\frac{2-1}{4}w-1\\\\=\frac{1}{w}-1

Hence, Second option is correct.

Apply the distributive property and the greatest common factor to write an equivalent expression. Enter your answers in the boxes. 32k+24= ?(?)

The distributive property looks like this: a(b+c) = ab + bc

We're going to apply this property in reverse.
We're starting with something like this ab + bc,
two terms which share stuff in common.
And we're going to factor out the common stuff.

32 and 24 are both divisible by 8.
Rewrite 32 and 24 as 8 times something.

32*k + 24 = 8*4*k + 8*3

And now factor an 8 out of each term,

8(4*k + 3)

Hope that makes sense! :)
