Answer:

After 13 weeks, Vicki and Jeb will have the same number of baseball cards.

Step-by-step explanation:

Let n be the required number of weeks after which Vicki and Jeb have the same number of baseball cards.

The number of cards Vicki will buy after n weeks = 210 + 15n

The number of cards Jeb will buy after n weeks = 275 + 10n

Since, these are equal,

210 + 15n = 275 + 10n

15n - 10n = 275 - 210

5n = 65

Divide both sides by 5.

n = 13.

Hence, after 13 weeks, Vicki and Jeb will have the same number of baseball cards.

Which statement best describes the area of Triangle ABC shown below?
PolarNik [594]

Answer:

it is half the area of a square of side length 8

Step-by-step explanation:

area of a square = l × b

= 8 × 8

= 64 cm^2

area of a triangle = b × h ÷ 2

= 8 × 8 ÷ 2

= 64 ÷ 2

= 32 cm^2

There are 420 students. 63 students were out sick. What percent of the student population is ill?
emmainna [20.7K]
To find the percentage,here's what we can do:
\frac{student \: out \: sick}{original \: population} \times 100\%

The percentage would then be:
=63/420×100%
=3/20×100%
=0.15×100%
=15%

Therefore the answer is 15%.

Hope it helps!

A quadrilateral has two angles that measure 222° and 81°. The other two angles are in a ratio of 6:13. What are the measures of
hram777 [196]

\sf\huge\underline{\star Solution:-}

\rightarrow <u>Ratio of two angles are 6:13.</u>

So, let the one angle be \sf{6x} and another be \sf{13x.}

As we know that,

Sum of all interior angles of a quadrilateral = \sf\pink{360°.}

So let's sum up the given angles,

\rightarrow \sf{222°+81°+6x+13x \:=\:  360°}

\rightarrow \sf{303+19x \:=\:  360°}

\rightarrow \sf{19x \:=\:  360-303}

\rightarrow \sf{19x \:=\:  57}

\rightarrow \sf{x \:=\:  \frac{19}{57}}

\rightarrow \sf{x \:=\:  3}

Hence, \sf{x \:=\:  3}

So, First angle \sf{= \:6x\: = \:6×3 \:=} \sf\purple{18°.}

Second angle \sf{= \:13x\: = \:13×3 \:=} \sf\purple{39°.}
