What is the answer for -7 x 7 please say the explanation too.

prisoha [69]

-7 x 7 = -49

We can first figure out 7 x 7, which will be 49. Once we have that, we can look at our negatives. If we have an odd number of negative signs, the answer will be negative. If we have an even number of negative signs, the answer will be positive. In this case, we only have 1 negative sign, and 1 is odd, therefore our answer will be odd.

ANSWER: -49

Hope this helps!

Agata [3.3K]

Answer:

Ratio as a fraction in simplest form is, $\frac{\text{17 correct}}{\text{3 incorrect}}$

Step-by-step explanation:

Ratio defined as the relationship between the quantities of something i.e,

a: b = $\frac{a}{b}$

Given: 51 correct : 9 incorrect

By definition of ratio:

51 correct : 9 incorrect = $\frac{\text{51 correct}}{\text{9 incorrect}}$

Divide both numerator and denominator by 3 we get;

$\frac{\text{17 correct}}{\text{3 incorrect}}$

then

The ratio as a fraction in simplest form is, 17 correct : 3 incorrect or $\frac{\text{17 correct}}{\text{3 incorrect}}$

7. A kite in the shape of a square with a diagonal 32 cm and an isosceles triangle of base 8 cm and sides 6 cm each is to be mad

grin007 [14]

Answer:

Step-by-step explanation:

diagonal = 32 cm

Area of square = $\dfrac{d^{2}}{2}$

$=\dfrac{32*32}{2}\\\\=512 \ cm^{2}$

Diagonal separate the square into two equal triangles.

Area of upper triangle that is shaded black = area of lower triangle = 512/2

= 256 cm²

Isosceles triangle:

a = 6 cm ; b = 6 cm c = 8cm

$s = \dfrac{a+b+c}{2}\\\\=\dfrac{6+6+8}{2}\\\\=\dfrac{20}{2}\\\\=10\\\\s-a = 10 - 6 = 4 \ cm\\\\s-b = 10-6 = 4 \ cm\\\\c - c = 10 - 8 = 2 \ cm\\\\Area = \sqrt{s*(s-a)(s-b)(s-c)}\\\\=\sqrt{10*4*4*2}\\\\=\sqrt{2 * 2 * 4 * 4 * 5}\\\\=4*2\sqrt{5}\\\\=8\sqrt{5}\\\\=8*2.24\\\\=17.92 \ cm^{2}$

Area of black shade paper = 256 + 17.92 = 273.92 cm²

Area of white shade paper = 256 cm²

Area of the isosceles triangle = s(s-a)(s-b)(s-c)
