Answer:

Percentage of boys have school dinners: 60%

Percentage of pupils in this class have school dinners: 65%

Step-by-step explanation:

1. There are: 6+4 = 10 boys in the class -> corresponding to 100 %

1 boy is corresponding to 100% :10 = 10%

6 in 10 have school dinners -> 10% x 6 = 60%

2. There are 10( boys) + 7 (girls) + 3 (girls) = 20 pupils in the class -> corresponding to 100%

1 pupil is corresponding to 100% : 20 = 5%

There are : 6 + 7 = 13 pupils who have school dinners

13 in 20 have school dinners -> 5% x 13 = 65%

Which sequences of transformations will map circle M onto circle N?

sergiy2304 [10]

Answer:

1: Reflect M across the x-axis

2: Dilate about the center by 3/2

Step-by-step explanation:

Given

See attachment for M and N

Required

Which maps M to N

The coordinates of the radius of the circles are:

$M = (5,5)$

$N = (5,-5)$

And the radius of circles are:

$r_M=2$

$r_N=3$

The first transformation from M to M' is:

- Reflect across the x-axis

The rule is:

$(x,y) \to (x,-y)$

$M(5,5) \to M'(5,-5)$

At this point, M' and N now have the same center but different radius.

The second transformation from M' to N is:

- Dilate about the center by dividing the radius of N by the radius of M

i.e.

$k =\frac{r_N}{r_M}$

$k =\frac{3}{2}$

At this point, M has been completely mapped to N.

HELP ME OUT PLS!!!!!

miskamm [114]

Answer:

x = 26

Step-by-step explanation:

Supplementary angles mean that when the two angles are added together, they add up to 180. With this info, we can set the two expressions equal to 180

124 + (2x + 4) = 180.

128 + 2x = 180 combine like terms

2x = 52 subtract both sides by 128

x = 26. divide both sides by 2
