Find the angle measure and round to the nearest Tenth. cos0 = 7/10 x = ? degrees

julsineya [31]

Step-by-step explanation:

ok so a translation is a shape being moves to a point,a reflection is basically mirrored from an opposite point, a rotation can be turned any way ,so it's telling you to do the points on a graph of x and y to make it match each point

A square picture with side length 30 cm is scaled by 60% on a photocopier the copy is then scaled by 60% again. What is the side

Sonja [21]

Answer:

10.8 cm

Step-by-step explanation:

we know that

1) A square picture with side length 30 cm is scaled by 60% on a photocopier

Remember that

$60\%=60/100=0.60$

so

The length of the first copy of the picture is

$30(0.60)=18\ cm$

2) The copy is then scaled by 60% again

so

The length of the second copy of the picture is

$18(0.60)=10.8\ cm$

25A2B is a 5-digit number. If the number is divisible by 5 and 9, find all the possible values of A and B. Explain also.

3241004551 [841]

Answer:

25020, 25920, 25425

Step-by-step explanation:

To find if our number is divisible by 5 the number must end with 0 or 5, divisibility by 9 is if sum of all numbers in number is divisible by 9,

We know B must end with 0 or 5

1. Case 25A20 sum of that number is 9 so if we pick 0 as A we have first number because 9/9=1

We can put A as 9 because 18/9=2

2. Case B = 0, sum is 14 so we need pick A as 4 to get 18.

Ginny's piggybank contained $8.80 in quarters, dimes, and nickels. there were two more than five times as many nickels as quarte

SSSSS [86.1K]

Answer:

There are 13 quarters, 67 nickels, and 22 dimes.

Step-by-step explanation:

The value of a quarter is $0.25, the value of dime is $0.10, and the value of a nickel is $0.05. Let there be q quarters, n nickels, and d dimes.

Let's write equations from the statements given:

"Ginny's piggybank contained $8.80 in quarters, dimes, and nickels.":

$0.25q+0.1d+0.05n=8.80$

"there were two more than five times as many nickels as quarters":

$5q+2=n$

"4 less than twice as many dimes as quarters":

$2q-4=d$

Plugging in equation 2 and 3 into equation 1, we can solve for q:

$0.25q+0.1(2q-4)+0.05(5q+2)=8.80\\0.25q+0.2q-0.4+0.25q+0.1=8.80\\0.7q=8.80+0.4-0.1\\0.7q=9.1\\q=\frac{9.1}{0.7}=13$

Substituting q = 13 into equation 2 will give us nickels:

$n=5q+2\\n=5(13)+2\\n=67$

Substituting q = 13 into equation 3 will give us dimes:

$d=2q-4\\d=2(13)-4\\d=22$

There are 13 quarters, 67 nickels, and 22 dimes.
