Answer:

512

Step-by-step explanation:

first you would write it with the other numbers it gives which should look like this: 4+(7-5) then you do the part that is in parentheses 7-5=2 then 4x4x4x4 which equals 256 then you multiply the two together and you should end up with 512

Amanda leaned a 15-foot ladder against the top of her house so she could get on the roof, which is 12 feet from the ground.

tester [92]

Using the Pythagorean theorem:

15^2 = 12^2 + X^2

225 = 144 + x^2

X^2 = 225 - 144

x^2 = 81

x = √81

x = 9

The distance is 9 feet.

The answer is A.

2 5/7+4 3/5= help please

Ainat [17]

Answer:

$7\frac{11}{35}$

Step-by-step explanation:

$2\frac{5}{7}+4\frac{3}{5}$

add the whole numbers

$2+4=6$

combine the fractions

$\frac{5}{7}+\frac{3}{5}$

LCM is 35 because 7 * 5 =35

$\frac{5}{7}=\frac{5\cdot \:5}{7\cdot \:5}=\frac{25}{35}$

$\frac{3}{5}=\frac{3\cdot \:7}{5\cdot \:7}=\frac{21}{35}$

$\frac{25}{35}+\frac{21}{35}=\frac{25+21}{35}$

$=\frac{46}{35}$

change the improper fraction into mixed number

$6+1\frac{11}{35}$

$=7\frac{11}{35}$

Dilate the given points distance from the origin (x,y) (0.8x, 0.8y) . The point (-10,-20) becomes & point (15,25) become

dalvyx [7]

Answer: The point (-10,-20) becomes (-8,-16) & point (15,25) becomes (12,20).

Step-by-step explanation:

When a point (x,y) is dilated by a scale factor k from the origin, then the new points become

$(kx,ky).$

The given rule of dilation : (x,y) →(0.8x, 0.8y)

The first point is (-10,-20), so its image will be

$(-10,-20)\to (0.8\times-10,0.8\times-20)=(-8,-16)$

So, the point (-10,-20) becomes (-8,-16).

The second point is (15,25), so its image will be

$(15,25)\to (0.8\times15,0.8\times25)=(12,20)$

So, the point (15,25) becomes (12,20).

Hence, the point (-10,-20) becomes (-8,-16) & point (15,25) becomes (12,20).
