Answer:

38 square inches

Step-by-step explanation:

The figure is a quadrilateral with one pair of parallel sides. That means it is a trapezoid, so the area formula for a trapezoid is applicable.

A = (1/2)(b1 +b2)h

The two parallel bases are 7 in and 12 in. The height is the perpendicular distance between them, 4 in. So, the area is ...

A = (1/2)(7 in +12 in)(4 in) = (1/2)(19 in)(4 in)

A = 38 in²

The area of the trapezoid is 38 square inches.

Answer:

<h2><u>Answer </u><u>:</u><u>-</u></h2>

We know that

The shape is trapezoid.

According to Question,

The area of trapezoid = ½(a + b) × h

a and b are parallel side of the trapezoid
H is the height of trapezoid

$\large \sf \: \dfrac{1}{2} \bigg(12 + 7 \bigg) \times 4$

$\large \sf \: 1 \times 19 \times 2$

$\large \sf \: 19 \times 2$

$\large \sf \: 38 \: in {}^{2}$

Answer:

Option C

Step-by-step explanation:

we have

$-6x^{2} -6x+12=0$

step 1

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$-6x^{2} -6x=-12$

step 2

Factor -6 leading coefficient'

$-6(x^{2} +x)=-12$

step 3

Complete the square

Remember to balance the equation by adding the same constants to each side

$-6(x^{2} +x+0.25)=-12-1.5$

$-6(x^{2} +x+0.25)=-13.5$

step 4

Rewrite as perfect squares

$-6(x+0.5)^{2}=-13.5$

simplify

$(x+0.5)^{2}=2.25$

Sally earns per hour = $12

Sally works for in a week = 16 hours.

So, Sally earns in a week = $12\times16=192$

Sally can save money each week= 20% of 192

$\frac{20}{100}\times192=38.40$

A. How much does she earn each week ? Sally earns $192 in a week.

B. How much money will she save each week? Sally will save $38.40 each week.

C. How much money will she save each month (assume there are 4.3 weeks in a month)

Savings of 1 week = $ 38.40

Savings of 4.3 weeks = $4.3\times38.40=165.12$

Hence, she will save $165.12 in a month.

D. How many months will it take her to save the money?

Total money needed = $1800

Number of months needed to collect this amount =

$\frac{1800}{165.12}=10.90$

Hence, it will take 11 months approx to save $1800.

GI bisects DGH so that m DGI is x-3 and mIGH is 2x-13 find the value of x

baherus [9]

x = 10

since GI bisects ∠DGH then ∠DGI = ∠IGH, hence

2x - 13 = x - 3 ( subtract x from both sides )

x - 13 = - 3 ( add 13 to both sides )

x = 10
