barbecue. How many ounces of meat did she buy?
Answer:
96
Step-by-step explanation:
1 pound=16 ounces
6x16=96
Answer:
She bought 96 ounces.
Step-by-step explanation:
When you convert 6 pounds into ounces it's 96 ounces.
1 pound equals 16 ounces.
16 ounces times 6 is 96.

8) Solve the system of equations by substitution
y = x + 2
3x + y = 10
Answer:
(2, 4)
Step-by-step explanation:
y = x + 2
3x + y = 10
3x + (x + 2) = 10
4x + 2 = 10
4x = 8
x = 2
y = (2) + 2
y = 4
Step-by-step explanation:
3x + y = 10
substituting the value of y = x + 2
=>3x + x+2 = 10
=>4x= 10-2
=>4x= 8
=>x= 8/4
=>x= 2
And, y= 2+2 = 4

Tom used the following steps to find the inverse of f(x), but he thinks he made an error.
Answer:
4
Step-by-step explanation:
He made the mistake in step 4
The correct step should be x +2 as two had the sign "-" when it was on the other side
Tom made a mistake in step 4, and to correct the mistake he should add 2 on both sides in step 4.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
Step 1: f(x) = 4x - 2
Step 2: y = 4x - 2
Step 3: x = 4y - 2
Step 4: x + 2 = 4y (add 2 on both sides)
Thus, Tom made a mistake in step 4, and to correct the mistake he should add 2 on both sides in step 4.

Rachael bought a snorkel and ear plugs for shallow diving. The snorkel cost $28.96, and the ear plugs cost $2.56. The sales tax of both items is 5%. How much did she pay in total?
Answer:
$33.10
Step-by-step explanation:
$28.96 + $2.56 = $31.52
$31.52 * .05 = $1.576 (round up) $1.58
$31.52 + $1.58 = $33.10
Answer:
Step-by-step explanation:
Total without sales tax
Snorkel = 28.96
Ear Plugs 2.56
Total 31.52
Sales tax = 5% of Total = 5/100 *31.52
Sales tax = 1.58 Rounded.
Total purchase = 33.10

Help !!!!!!!!!!!!!!!!!!!!!!!
Answer:
<ADB = 75 degrees
Step-by-step explanation:
We know, a straight line has an angle of 180 degrees.
A = (180-143) = 37 degrees.
A + C = (37 + 38) = 75 degrees.
The angles of a triangle will always add up to 180 degrees.
<ADC = (180-75) = 105 degrees.
So,
<ADB = (180-105) = 75 degrees.

The systolic blood pressure (BP) of adults in the USA is nearly normally distributed with a mean of 121 and standard deviation of 16 . Someone qualifies as having Stage 2 high blood pressure if their systolic blood pressure is 160 or higher. (a) Around what percentage of adults in the USA have stage 2 high blood pressure
Answer:
Around 0.73% of adults in the USA have stage 2 high blood pressure
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 121 and standard deviation of 16.
This means that [tex]\mu = 121, \sigma = 16[/tex]
Around what percentage of adults in the USA have stage 2 high blood pressure
The proportion is 1 subtracted by the p-value of Z when X = 160. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{160 - 121}{16}[/tex]
[tex]Z = 2.44[/tex]
[tex]Z = 2.44[/tex] has a p-value of 0.9927.
1 - 0.9927 = 0.0073
0.0073*100% = 0.73%
Around 0.73% of adults in the USA have stage 2 high blood pressure

Karly buys a model car for $64. Then she spends 2 times as much on supplies to build the model car. How much does Karly spend altogether?
Answer:
192
Step-by-step explanation:
Supplies = 2 model cost
= 2*64 = 128
Total cost = model + supplies
= 64 + 128
=192
You buy a tree That is 7" high and plant it in your front yard and it grows 5 inches every year! You plant an Oak that is 11" high and grows 3 inches per year!
1. Write two equations to show the height of each tree at any given time (one equation for each tree). Define the variables that you use. Make sure you specify the units.
2. Solve the system to find out how long it takes for the trees reach the same height.
3. Interpret your answer in a complete sentence.
Problem 1
x = number of years
y = height of the tree in inches
The equation for the first tree (your teacher doesn't mention the type of it) is y = 5x+7.
The 5 represents the slope or rate of change. It tells us how fast the tree is growing per year. The 7 at the end is the y intercept, and the starting amount. Refer to y = mx+b form.
Similarly, the equation for the second tree (oak tree) is y = 3x+11 because it starts off at a y intercept of 11 inches and increases by 3 inches per year, aka the slope.
I recommend making a table of values to see how each tree grows throughout the years.
--------------------
Answer:
The two equations are
y = 5x+7
y = 3x+11
==========================================================
Problem 2
Let's use substitution to solve for x and y
y = 3x+11
5x+7 = 3x+11 .... replace y with 5x+7
5x-3x = 11-7
2x = 4
x = 4/2
x = 2
Use this x value to find y
y = 3x+11
y = 3*2+11
y = 6+11
y = 17
Or you could say
y = 5x+7
y = 5*2+7
y = 10+7
y = 17
We get the same y value either way, which helps confirm the answer.
--------------------
Answer:
(x, y) = (2, 17)
==========================================================
Problem 3
The result of the previous problem was (x, y) = (2, 17) which is a compact way of saying that x = 2 and y = 17 pair up together.
Going back to how we defined x and y, we can see that x = 2 means that 2 years have passed and y = 17 means that both trees are 17 inches tall.
Interpretation: At the 2 year mark, both trees are 17 inches tall.
Note: 17 inches = 12 in + 5 in = 1 ft + 5 in

Required
Find x
To solve for x, we make use of:
[tex]x + 50^o + 60^o = 180^o[/tex] --- angles in a triangle
[tex]x + 110^o = 180^o[/tex]
Collect like terms
[tex]x = 180^o-110^o[/tex]

A bag contain 5 red marbles, 4 blue marbles and 6 green marbles. If three marbles are drawn out of the bag, what is the exact probability that all three marbles drawn will be red?
Answer:
2/91.
Step-by-step explanation:
There are 15 marbles in the bag.
Prob(First draw is red) = 5/15 = 1/3.
Prob(Second draw is red) = 4/14 = 2/7.
Prob(Third draw is red) = 3/13.
So probability that all 3 are red = .1/3 * 2/7 * 3/13
= 6/273
= 2/91.

13. Write an equation in slope-intercept form of the line that passes through the points (4.2) and (1.-7).
Answer:
The answer is [tex]y=3x-10[/tex]
Step-by-step explanation:
You use the formula [tex]y_{2} -y_{1} /x_{2} -x_{1}[/tex]
Which will give you 3. So the slope is 3/
Then you continue with the equation- [tex]y=mx+b[/tex] (m represents the slope which is 3) We use then use any point but I used (4,2) to plug into the equation.
After using that equation, you get the y-intercept as -10. So, the equation is [tex]y=3x-10[/tex]
find the value of x (URGENT/GIVING BRAINLIEST)
Answer:
x=25
Step-by-step explanation:
The angles 126 and (5x+1) are equal. The equation that is used is 5x+1=126.
To solve the equation, subtract 1 from both sides
5x+1-1=5x 126-1=125.
Simplify the equation. 5x=125
Divide both sides by 5. 5x/5=x 125/5=25
You would get x=25 eventually.
