The answer is B i did it yes. Thanks
Answer:
4:7
Step-by-step explanation:
4:7
they make 7 cakes in total (3:4 = 7).
there are 4 vanilla cakes.
therefore, the ratio of vanilla cakes to the total number of cakes is 4:7.
Answer:
1/4(x+2) = 3
Step-by-step explanation:
Let's do this one thing at a time.
1/4 of a number means 1/4 times a number. We'll use x to represent "a number," so we have
1/4x
But wait: we need to add 2 to a number (sum = addition). So we have
1/4(x+2)
This is three, so we know that expression is all equal to 3.
1/4(x+2) = 3
Answer:
if i can be brainliest that would be great
f(x) = x^2+3x-10
f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5
f(x+5) = (x^2+10x+25)+3(x+5)-10
f(x+5) = x^2+10x+25+3x+15-10
f(x+5) = x^2+13x+30
Compare this with x^2+kx+30 and we see that k = 13
Factor and solve the equation below
x^2+13x+30 = 0
(x+10)(x+3) = 0
x+10 = 0 or x+3 = 0
x = -10 or x = -3
The smallest zero is x = -10 as its the left-most value on a number line.
Answer:
In total, 
permutations of three items can be selected from a group of six distinct elements.
In particular, there are 
ways to order three distinct items.
.
Step-by-step explanation:
The formula 
gives the number of ways to select and order 
items from a group of 
distinct elements.
To select and order three items from a group six distinct elements, let 
and 
. Apply the formula:
.
In other words, there are unique ways to select and order three items (select a permutation of three items) from a group of six distinct elements.
Consider: what's the number of ways to order three distinct items? That's the same as asking: how many ways are there to select and order three items from a group of three distinct elements? Let 
and . Apply the formula for permutation:
.
To find the permutations, start by selecting one element as the first of the list. A tree diagram might be helpful. Refer to the attachment for an example.
