Answer:
Picture 1. (x+9)(x+5)
Picture 2. I dont know it im sorry
Step-by-step explanation:
We can let the percentage be p%
list an equation out from the given information.
92 x p% = 23
Flip 92 into the other side, turning it into ÷92
P% = 23 / 92
= 0.25
0.25 can be transformed into percentage, by moving the decimal place 2 places to right. Therfore, 0.25 is equal to 25.0%, which is 25%
Therfore, 25% of 92 is 23
Just plug in the given values of sec x and tan x and see if they fit
For example if sec x = 1 and tan x = 1
then we have 2*(1^)2 - 1 = 1
2 - 1 = 1
so a and d are true
they may be more Just try them out
Answer:
The Product is negative three (-3)
WHILE
The number is negative one (-1)
Step-by-step explanation:
Since seven more than the product gives 4.
This means 7 + product = 4
By subtracting 7 from both sides we get product as -3.
And since the product of the number and 3 is equal the product
This means number X 3 = -3
By dividing three from both sides you get -1.
Answer: 1,045 passengers
Step-by-step explanation:
This question involves multiple steps. Let's first try to figure the number of children on the cruise.
The ratio of girls to the total number of children was 2:5. There are 198 boys.
This information tells me that for every 5 children, there's 2 girls and 3 boys.
Based off of this information, we can divide the total number of boys by 3 in order to find the number of children.
198÷3=66
Let's multiply 66 by 5 since that's the number of groupings based off the ratio.
66×5=330
Let's check the number of children. Since the ratio of girls to total children is 2:5 and we already confirmed there's 198 boys, there should be 132 girls. We can turn this ratio into a fraction where 2/5 of the children are girls. we can confirm this by multiply 330 by 2/5 (0.4) and getting 132.
There are 330 children on the cruise.
The ratio of the number of adults to the number of children was 13:6.
For every 6 children, there were 13 adults. Let's divide the number of children by 6 in order to find the number of groupings.
330÷6=55
Let's now multiply the groupings by 13 to find the number of adults.
55×13=715
So there should be 715 adults and 330 children on the cruise.
715+330=1,045
