Answer:
3.92 approximately 4
Step-by-step explanation:
let us first find angle at F
40⁰+50⁰+F= 180 (sum of angles in a triangle)
90⁰+F= 180⁰
F= 180⁰-90⁰
F = 90⁰
using sine rule
3/sin 50 = x/sin 90
3/0.7660= x/ 1
0.7660x=3
x= 3/0.7660
x= 3.92 approximately 4
First, let's solve the inequality
2.9 (x+8) < 26.1
2.9x + 23.2 <26.1
2.9x < 26.1 -23.2
2.9x <2.9
dividing both sides by 2.9 we get:
x < 1
so, it is the last numberline graph, because it contains an empty circle at 1 on the numberline, which means it doesn't include 1. but all numbers less than 1
Answer:
Step-by-step explanation:
Factor
x^2-6x+8<0
(x-2)(x-4)<0
For this to be less than zero the factors must have opposite signs.
x>2 and x<4
2<x<4
So x is all real numbers between 2 and 4 or in interval notation
x=(2,4)
Negative 72.75 is your product. It is very simple once you understand it.
Answer: 21/35 girls 14/21 boys
Step-by-step explanation: To find the number of girls, multiply
3/5 × 35 = 21 girls
You can subtract 35-21 to find the number of boys, or multiply
2/5 × 35 = 14 boys
Realizing that 35/5 = 7, we can multiply
7/7 × 3/5 to get the <em>fractional equivalent of girls 21/35</em>
and 7/7 × 2/5 to get the <em>fractional equivalent of boys 14/35</em>
