The sum of two consecutive odd numbers is 28. Find their product
We will see that the first odd number is 13 and the second odd number is 15, the product is:
P = 13*15 = 195
How to find the two consecutive odd numbers?
Let's say that the first number is x, the next odd number will be x + 2.
The sum of these two odd numbers must be 2, then we need to solve the linear equation:
x + (x + 2) = 28
We can solve that for x:
2x + 2 = 28
2x = 28 - 2 = 26
x = 26/2 = 13
Then the first number is x = 13 and the second number is x + 2 = 13 + 2 = 15.
The product of these two numbers is:
13*15 = 195

A washer and dryer cost a total of $964 . The cost of the washer is three times the cost of the dryer. Find the cost of each item.
Answer:
A washer and dryer cost a total of $964 . The cost of the washer is three times the cost of the dryer. Find the cost of each item.
Answer: 96$
Answer:
The washer costs $723 and the dryer $241.
Step-by-step explanation:
Represent the cost of the washer by w and that of the dryer as d.
Then w = 3d.
Since w + d + $964, we get 3d + d = $964, or 4d = $964, or d = $241.
Three times that is $723.
The washer costs $723 and the dryer $241.

3w(x + y) + 4z(x - y) correctly shows the first step when factoring 3wx + 3wy - 4zx - 4zy by grouping. Option B
How to solve thisTo factor by grouping, we first pair up the terms and then check if there is a common factor in each pair.
The given expression is 3wx + 3wy - 4zx - 4zy
First, put the terms into pairs.
The simplified version of the expression (3wx + 3wy) - (4zx + 4zy) is 3wx + 3wy - 4zx - 4zy.
Next, separate and remove the terms that are the same from each group.
The expression 3w(x + y) - 4z(x + y) can be simplified to (3w - 4z)(x + y).
This is a summary:
In option B, we have correctly put the terms together in pairs and found the common factors in each group. In the first group, we take out 3w from 3wx and 3wy, and in the second group, we take out 4z from 4zx and 4zy. This means that the expression is correct when it is written as factors.

Victoria is at an elevation of 150 feet. She hikes down to an elevation of 120 feet in 40 minutes. Then she hikes down to an elevation of 100 feet in 30 minutes.
Answer:
Answer: First portion is greater than second portion.
Step-by-step explanation:
Time taken to hiked down a trail = 10 minutes
Change in elevation = (-) 170 feet
Speed is given by
\begin{gathered}Speed=\frac{Distance}{Time}\\\\Speed=\frac{170}{10}\\\\Speed=17\text{ feet per minute}\end{gathered}

Change in elevation = (-)220 feet
Speed is given by

Distance
\begin{gathered}Speed=\frac{220}{20}\\\\Speed=11\text{ feet per minutes}\end{gathered}

So, we can see that first portion of the hike where he hiked down a trail at a steady rate for 10 minutes and her change in elevation was (-) 170 feet, was her rate of change in elevation greater.
As 17 feet per minutes is greater than 11 feet per minutes.

According to a weather report, there is a 11% chance it will rain tomorrow. What is the probability that it will not rain tomorrow?
Answer:
0.78
Step-by-step explanation:
P(R)=22/100=0.22
R=1
1-0.22=0.78
According to a weather report on the probability that it will rain tomorrow, the probability that it will not rain tomorrow is 89%.
What is Probability?
Probability is simply the likelihood that something or an event is to happen.
Now, the probability that an event will not occur is one minus the probability that the event will occur.
Given the data in the question;
Probability that it will rain tomorrow p = 11%Probability that it will not rain tomorrow p⁰ = ?The probability that it will not rain tomorrow is one minus probability that it will rain tomorrow.
p⁰ = 1 - p
p⁰ = 1 - 11%
p⁰ = 1 - ( 11 / 100 )
p⁰ = 1 - 0.11
p⁰ = 0.89
p⁰ = 89%
Therefore, According to a weather report on the probability that it will rain tomorrow, the probability that it will not rain tomorrow is 89%.

Tammy cuts four identical circles from a square piece of black poster board as shown. What is the area of the leftover poster board?
a) 6.240 square feet
b) 5.375 square feet
c) 18.760 square feet
d) 19.625 square feet
Answer:
B) 5.375
Step-by-step explanation:
The circles are half the square so their diameter will be half the length of the square
d=5/2=2.5
the formula is
area of shaded portion-area out unshaded portion
area of a square= l×l
5×5=25
area of a circle=πr^2
but since there are 4 circles it becomes 4πr^2
r=d/2=2.5/2=1.25
area of unshaded portion= 4×3.14×1.25×1.25
=19.625
area of leftover=25-19.625
= 5.375

Write an expression equivalent to the expressions 12x+16y using the gcf
pls help
Answer:4(3x+4y)
Step-by-step explanation: the gcf of 12x+16y is 4. we factor out 4 by dividing both terms by 4.
Answer:
[tex]4(3x+4y)[/tex]
Step-by-step explanation:
Hey there!
This would be the correct answer because the GCF of 12 and 16 is 4.
Now that we know that it is 4 we can divide the eqiasion by 4 and then you get
[tex]4(3x+4y)[/tex]
If you need to ckeck if this answer is corret then you will need to use the distributive property to distribute 4 to 3y and 4y.
The equasion would then look like this
[tex](4(3x)) (4(4y))[/tex]
Next you would need to solve the equasion to get the origional equasion

Last year a company spent a total of £2400 on advertising. This year they spent £2796 What was the percentage increase in their spending on advertising?
Answer:
16.5%
Step-by-step explanation:
[tex] \frac{396}{2400 } \times 100[/tex]The percentage increase in their spending on advertising will be 16.5%.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Last year an organization spent a sum of £2400 on publicizing. This year they burned through £2796.
Then the percentage increase in their spending on advertising will be given as,
P = [(2796 - 2400) / (2400)] x 100
P = (396 / 2400) x 100
P = 0.165 x 100
P = 16.5%
The percentage increase in their spending on advertising will be 16.5%.
