4q+5(-5)/5=7
5x5=-25
4q-25/5=7
q=15
Answer:
q = 15
Step-by-step explanation:
We need to use inverse operations.
5 + 7 = 12
now the equation is 4q/5 = 12
what we do is 4 = 5 ⋅ 12
5 x 12 = 60
60 divided by 4 = 15
q = 15

A right triangle has one angle that measures 40°. What is the measure of the other acute angle?
Answers
Answer:
50
Step-by-step explanation:
a right triangle is 90 degrees so if one angle is 40 the other has to be 50.
Answer:
50º
Step-by-step explanation:
Since all angles of a triangle have a sum of 180º, we can add 90º (since it's a right triangle) and 40º. This gives us 130º, which we can then subtract from the 180º total. The answer is then 50º.
under which of the following conditions is it preferable to use stratified random sampling rather than simple random sampling?
Answers
Answer:
The population can be divided into strata so that the individuals in each stratum are as much alike as possible.
Step-by-step explanation:
In short, if you can group the population into subgroups and are interested in their sub properties, then use stratified random sampling. If not, and interested only in the entire population as a whole, then use simple random sampling.
Simple random sampling, as the name suggests, is simply sampling randomly from the population. It doesn't make any assumptions of sub-classifications about the given population and is only interested in sampling the population as a whole representative.
Stratified random sampling, as the name suggests, does sampling on strata( parts or subgroups divided in the population). The sampling then is done from each group proportionate to the group's size versus the population size.
One example is when you've got red, green and blue colored balls as the population and you want to sample the population based on colors, then the colored groups are strata and thus, the sampling will be done on subgroups and such type of sampling will be called as stratified random sampling.
Simple random sampling doesn't care about sub-properties in the population. It consider the population as whole and doesn't differentiate classes in the population, unlike stratified random sampling.

Rectangle PQRS with vertices P(- 6, 9) , Q(3, 6); R(0, - 9) and S(- 9, - 6)
a) dilated by a scale factor of 1/3 with the origin as the center of dilation
b) reflection in the line y = - x
Answers
Answer:
multiply the original coordinate by 3 so its c
Step-by-step explanation:
multiply the original coordinate by 3
The image with the dilation of scale factor of 1/3 is P'Q'R'S' are (-2. 3),(1, 2),(0, -3) and (-3, -2)respectively.
How dilation of a rectangle works?Dilation of a figure will leave its sides get scaled (multiplied) by same number. That number is called the scale factor of that dilation. Also If the Dilation is from the center of the rectangle, then the distance of all the points of the rectangle from its center will get scaled by that one dilation factor.
The dilation with scale factor of 1/3 with the origin as the center of dilation,
Let the coordinates are (x, y) -- (kx, ky); where k is the scale factor i.e, 1/3.
This can be written as; (1/3x, 1/3y).
For the point P(- 6, 9)
The image of P' = (-2. 3)
For the point Q(3, 6)
The image of Q' (1, 2)
For the point R(0, - 9)
The image of R' (0, -3)
For the point S(- 9, - 6)
Image = (-3, -2)
Therefore, the image with the dilation of scale factor of 1/3 is P'Q'R'S' are (-2. 3),(1, 2),(0, -3) and (-3, -2)respectively.
Part a) the reflection in the line y = -x then image triangle P'Q'R'S';
P' = (-2, 2)
Q' = (1, -1)
R' = (0,3)
S' = (-3,3)

Angles opposite to the equal sides of an isosceles triangle are equal, so the third angle in this triangle is also 61. Now, you know all the angles in the triangle, you can use the Triangle Sum Theorem, which says that all the angles in a triangle add up to 180.
x + 61 + 61 = 180
x + 122 = 180

Answer:
a° = 58°
b° = 48°
c = 74°
d° = 122°
Step-by-step explanation:
Angles on a straight line add up to 180°
58° + d° = 180°
d° = 180° - 58° = 122°
Alternate angles are equal.
a° = 58°
Angles in a triangle add up to 180°.
48° + 58° + c° = 180°
106° + c° = 180°
c° = 180° - 106° = 74°
Angles on a straight line add up to 180°
74° + 58° + b° = 180°
132° + b° = 180°
b° = 180° - 132° = 48°
