Jasmyn uses 42% of a gift card to buy groceries if she spent $67.20 on groceries, how much was on the gift card to begin with
lapo4ka [179]

Answer:

The card was worth $160.

Step-by-step explanation:

It is given that:

Percent of gift card used = 42%

Cost of groceries = $67.20

Let,

x be the total amount on gift card.

42% of x = 67.20

\frac{42}{100}x=67.20

0.42x = 67.20

\frac{0.42x}{0.42}=\frac{67.20}{0.42}\\x=160

Therefore,

The card was worth $160.

1 .the base of a trapezoid are 11 meter and 14 meters.its height is 10 meters . what is the area of the trapezoid?
kvasek [131]
Question 1
Use the formula for the area of a trapezoid. a and b are the bases. h = height.

A= \frac{a+b}{2}h=\frac{11+14}{2}*10 = \frac{25}{2}*10 = 12.5*10 = \boxed{125\ m^2}

Question 2
Use the formula for the area of a rhombus. p and q are the diagonals.

A = \frac{pq}{2} = \frac{21*32}{2} = \frac{672}{2} = \boxed{336\ m^2}

Question 3
Use the formula for the area of a parallelogram. b is the base and h is the height.

A = bh = 36*45 = \boxed{1620\ in^2}

What’s the answer to this?
Hoochie [10]

Answer:

The missing term is:

a_2=14

Step-by-step explanation:

Considering the geometric sequence

2,\:?,\:98,\:...

Here,

a_1=2

a_3=98

a_2=?

The general term of a geometric sequence is given by the formula:

a_n=a_1\cdot \:r^{n-1}

where a_1 is the initial term and r the common ratio.

as

a_3=a_1\cdot \:r^{3-1}

98=2\cdot \:r^{3-1}         ∵ a_1=2

\mathrm{Switch\:sides}

2r^{3-1}=98

\mathrm{Divide\:both\:sides\:by\:}2

\frac{2r^{3-1}}{2}=\frac{98}{2}

r^{3-1}=49

r^2=49

\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}

r=\sqrt{49},\:r=-\sqrt{49}

r=7,\:r=-7

Taking positive value of r = 7

a_2=a_1\cdot \:r^{n-1}

putting r = 7

a_2=2\cdot \:7^{2-1}

a_2=2\cdot \:7

a_2=14

So, the sequence becomes  2,\:14,\:98,\:...

Therefore, the missing term is:

a_2=14
