Answer:
The vertex would be (6,1)
Step-by-step explanation:
The vertex is the midway between the focus and the directrix. The X of the vertex would be the same but to get the Y of the vertex you would need to take the average of the Y values. (6, 4 + (-2)/2) (6,1)

What is consecutive number?
Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers.
Here, let the age of youngest sibling be x years
the age of middle sibling be (x+1) years
the age of oldest sibling be (x+2) years
According to question,
x + (x+1) + (x+2) = 42
3x + 3 = 42

Hazel is putting together charm bracelets. For each bracelet 1/5 of a yard of string and 12 charms. hazel has 5/8 of a yard of string and 96 charms. she makes the charm bracelet until all of the string is gone. what fraction of charms did she use?
Answer:
3/8
Step-by-step explanation:
First, find the number of bracelets she's able to make with her string. She has 5/8 of a yard and uses 1/5 per bracelet. To divide the number of yards she has by the number she uses, multiply 5/8 by the reciprocal of 1/5 (5/1).
5/8 * 5/1 = 25/8
25/8 is 3.12500, which is the number of bracelets she can make. It rounds down to 3 since she can't make 0.12500 bracelets.
Now, find how many charms she used. 3 bracelets * 12 charms each is 36 charms in total.
So she used 36/96 of her charms. This can be simplified to 3/8.
Answer:
37/96 hazel has
Step-by-step explanation:
1/5 times 12=60
so Hazel uses 1 yardd for 60 charms, so for 5/8 yard Hazel would use 5/8×60=37.5.
since Hazel isn't able to use a fraction of a charm, she would use 37 charms
37/96 Charms Hazel has

Hello!

Angles in a triangle sum up to 180°, so:
180° = 58° + 58° + m∠3
Combine and subtract:
180° = 116° + m∠3
64° = m∠3

A survey revealed that 20% of workers at a company were satisfied with their job. If 30 workers selected this option. How many total workers are at the company? Use the model below to help you solve the question.
Answer:
150 workers are at the company
Step-by-step explanation:
If 20% of the workers is equal to 30 workers than in order to find 100% of the worker you need to multiply the percentage with a number that makes it 100% and then multiply that number to the 30 workers so
20% * 5 = 100%
30 * 5 = 150
so 100% of the workers is equal to 150 workers
