ANSWER TO 4 AND 5 PLEASE ASAP
Answer:
4) 2/6 or 1/3
5) 42/110 or 21/55
Step-by-step explanation:
4) there are two red options out of a total of 6 options, so 2/6
5) 7 red out of total of 11, so 7/11 · 6/10 = 42/110
To get the fraction 6/10:
we reduce 7 to 6 because there is one less red than originally
we reduce 11 to 10 because there is one less from the initial total
Triangle ABC is graphed on a coordinate plane with vertices at A(-3, 7), B(9,-8), and C(-5, -6). If triangle ABC is dilated
by a scale factor of 2 with the origin as the center of dilation to create A'B'C', what will be the coordinates of the dilated
vertex of B'?
Answer:
B' = (18, -16)
Step-by-step explanation:
Dilating means to stretch or shrink a figure. The scale factor tells us how much we are stretching or shrinking. The scale factor is 2, so the coordinates are multiplied by 2.
Use the Law of Cosines to solve for the side BC. Round your answer to the point
nearest whole number. Write the value only *
Answer:
BC = 50
Step-by-step explanation:
Law of Cosines:
c^2 = a^2 + b^2 - 2ab*cosy (c is BC)
c^2 = 30^2 + 21^2 - 2(30)(21)cos123
c^2 = 900 + 441 - 1260*(-0.888)
c^2 = 1341 - (-1118.841)
c^2 = 2459.841
c = 49.597
c = 50

A taxi charges a flat fee of $3.00, plus an additional $1.25 per mile. Antonio can spend no more than $18. Choose the inequality that represents the number of miles he can ride, an describes the solution set.
Answer: 1.25m + 3 ≤ 18; Antonio can ride 12 or fewer miles
Step-by-step explanation: so you can break down the answer choices and only have a and b left because no more than means this sign: ≤
and 1.25 is the cost for each mile so your multiplying m and 1.25 and then you add that with 3.

The measure of angle PST 129 degrees after applying the properties of the triangle.
What is the triangle?In terms of geometry, a triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
It is given that:
The triangle is shown in the picture.
The equation can be made:
5x - 9 = (180 - (11x - 3))
5x + 11x = 180 + 3 + 9
16x = 192
x = 192/16 = 12
The measure of angle PST = 11x - 3
= 11(12) - 3
= 129 degrees
Thus, the measure of angle PST is 129 degrees after applying the properties of the triangle.

The ratio of teachers to students at Priory School is 2:27
What is school's total population if there are 42 staff
Answer:
609
Step-by-step explanation:
ratio of teachers to students at Priory School =2:27
Let X= total number of both the students and the teacher
Ratio of teacher=( 2/29)X
Ratio of student is (27/29 )X
But total number of teacher = 42
2/29 ×X =42
2X= 42×29
2X=1218
X= 609
Hence, school's total population is 609
