1/10 because one girl out of ten students wears glasses

Answer:

1/10

Step-by-step explanation:

The fraction 5/10 is equal to 1/2 and 1/5 of the girls wears glasses so if you multiply 1/2 and 1/5 you get 1/10.

\frac{1}{5}·\frac{1}{2}= \frac{1}{10}

When multiplying fractions you multiply across so the numerators are multiplied together and the denominators are multiplied together.

What single decimal multiplier would you use to decrease by 6% followed by a 7% increase?
expeople1 [14]

Answer:

the single decimal multiplier is 1.0058

Step-by-step explanation:

Let us have 100

Decreasing by 6% will be

100 - 0.06(100)

= 94

Increasing by 7%

= 94 + 0.07(94)

= 100.58

So

to get the single decimal multiplier,

we have 100.58/100 = 1.0058

Will give brainliest <br> A ?<br> B?<br> C ?
dolphi86 [110]

Answer:

A: 180°         B: 360°         C: 540°

Step-by-step explanation:

A: The measures of interior angles of a triangle sum to 180°. Since figure ABC is a triangle, the interior angles of figure ABC sum to 180°.

B: We can see the quadrilateral ACDE is a trapezoid. If you can see, the trapezoid can be split into two triangles if you connect points C and E. As U mentioned before, the measures of interior angles of a triangle sum to 180°. Since we know figure ACDE can be split into <u>two triangles</u> we have to do: 180x2 which is 360°.

C: Now that we know the Pentagon ABCDE can be split into 3 triangles(1 from figure ABC and 2 from figure ACDE), we have to multiply 180 by 3 because like I mentioned before, the measures of interior angles of a triangle sum to 180°. So, 180x3=540°.

The team first experiments with changing the position of the curved pit. In the computer program, the vertex begins on the origi
Advocard [28]

Answer:

Step-by-step explanation:

This question is incomplete; find the complete question in the attachment.

Given curve is modeled by the quadratic equation,

y = x²

If the curved pit is shifted 2 units down,

Equation of the translated curve will be,

y = x² - 2

If the curved pit is translated (shifted) by 2 units left,

Equation of the new curve will be,

y = (x + 2)²

If the curved pit is shifted by 2 units right,

Equation of the translated curve will be,

y = (x - 2)²

If the curved pit is shifted 2 units up,

Equation of the translated curve will be,

y = x² + 2
