Answer:

256 cm^2

Step-by-step explanation:

2 of triangulars can be together to become a new square.

because these 2 triangulars have a symmetric shape.

So the all area is 10×16 (the square in the center) + (6×16)

All area is 160 + 96

= 256 cm^2

* the formular of the square area is the width × the length

The vendor has to sell 88 gingerbread houses to earn a profit of $665.60 and there is no chance that the vendor will earn $1500.

Given an equation showing profits of A Christmas vendor as

P=-0.1g^{2}+30g-1200.

We have to find the number of gingerbread houses that the vendor needs to sell in order to earn profit of $665.60 and $1500.

To find the number of gingerbread houses we have to put P=665.60 in the equation given which shows the profit earned by vendor.

665.60=-0.1g^{2}+30g-1200

0.1g^{2}-30g+1200+665.60=0

0.1g^{2}-30g+1865.60=0

Divide the above equation by 0.1.

g^{2}-300g+18656=0

Solving for g we get,

g=[300±\sqrt{(300)^{2}-4*1*18656 }]/2*1

g=[300±\sqrt{90000-74624}]/2

g=[300±\sqrt{15376}]/2

g=(300±124)/2

g=(300+124)/2       , g=(300-124)/2

g=424/2,  g=176/2

g=212,88

Because 212 is much greater than 88 so vendor prefers to choose selling of 88 gingerbread houses.

Put the value of P=1500 in equation P=-0.1g^{2}+30g-1200.

-0.1g^{2}+30g-1200=1500

0.1g^{2}-30g+1500+1200=0

0.1g^{2}-30g+2700=0

Dividing equation by 0.1.

g^{2}-300g+27000=0

Solving the equation for finding value of g.

g=[300±\sqrt{300^{2} -4*1*27000}]/2*1

=[300±\sqrt{90000-108000}] /2

=[300±\sqrt{-18000}]/2

Because \sqrt{-18000} comes out with an imaginary number so it cannot be solved for the number of gingerbread houses.

Hence the vendor has to sell 88 gingerbread houses to earn a profit of $665.60 and there is no chance that the vendor will earn $1500.

Anja represents the inequality 4-g/8 &lt; - 15 with the phrase “the quotient of the difference of 4 and a number and 8 is at lea
scoundrel [369]

Answer:

Anja’s phrase should have ended with “less than –15”, not “at least –15”.

Step-by-step explanation:

Given the statement:

Anja represents the inequality \frac{4-g}{8}< -15

with the phrase “the quotient of the difference of 4 and a number and 8 is at least –15.”

Let the number be g.

“the quotient of the difference of 4 and a number and 8" translated to \frac{4-g}{8}

"at least" means \leq

then;

“the quotient of the difference of 4 and a number and 8 is at least –15.” translated to \frac{4-g}{8}\leq -15

Therefore, Anja’s phrase should have ended with “less than –15”, not “at least –15”.

Please Help!!!!!<br><br> Which method can you use to prove these triangles congruent?
Trava [24]

Answer: The HL Theorem.

Step-by-step explanation: We are given that the triangles have a congruent 90 degree angle and two congruent sides. This would indicate towards SAS but in this case, that doesn't work because the angle is not in between the two congruent sides. We know that the triangles are right, and that their hypotenuses are congruent and that one leg is congruent. Thus, the answer must be HL (hypotenuse & leg).

6 to the power of 8 divided by 6 to the power of 4
tensa zangetsu [6.8K]

Answer:

7.716049382716049e-4‬ or 1,296

Step-by-step explanation:

If 6 is to the power of 8 and my mind is not mistaken. Then it's 6^8=1,679,616 and then divide that by 6 to the power of 4 is 6^4=1,296. In the end with the numbers set. 1,679,616 Divided by 1,296 or 1,296 divided by 1,679,616.
