Answer:
26
Step-by-step explanation:
[(7+3)5-4]/2+3
-To solve this equation you have to use PEMDAS
P- Parentheses
E- Exponents
M- Multiplication
D- Division
A- Addition
S- Subtraction-
- With MD and AS you work left to right of the equation since they are in the same spot. (PE[MD][AS])
Step 1) [(10)5-4]/2+3
- First you do "P," parentheses, so you add 7+3=10
Step 2) [50-4]/2+3
- Next you do "M," multiplication, and multiply 10x5=50
Step 3) [46]/2+3
- Then you do "S," subtraction, and subtract 50-4=46
(FYI: Steps 1-3 were still in the parentheses. We had to start with the parentheses in the parentheses, work PEMDAS, and now we are out of the parentheses and have to work PEMDAS on the rest of the problem.)
Step 4) 23+3
- Now we do "D," division, and divide 46/2=23
Step 5) 23+3=6
- Finally we do "A," addition, and add 23+3=26 so the answer is 26
(FYI: "/" means division)

in a hypothesis test, if the computed p-value is less than 0.001, there is very strong evidence to
Answer: reject the null hypothesis
Explanation:
If the p-value is smaller than the significance level alpha, then we reject the null. You can think of the p-value being the probability that the null is correct. If the p-value is below a certain threshold (the significance level), then we can be fairly confident that rejecting the null is a good decision.
Your teacher or textbook might have brought up the phrase "If the p-value is low, then the null must go" as a way to help remember this rule. If the alpha level isn't stated, then usually it defaults to 0.05

At the fruit stand, Kim bought 6 apples for 45¢ each, 1 bunch of bananas for $1.00,
7 pears for 57¢ each, and 3 oranges for 42¢ each. How much did Kim spend at the
fruit stand?
The answer *SHOULD* be 8.95$.
Step-by-step explanation:
So we do 6 x 0.45 because we are doing 6 apples times 45 cents which is 0.45 .
So 6 x 0.45 = 2.70$
Then , we don't do too much for the bananas due to the fact it is only 1 bunch so if 1 bunch is 1.00$ and they only got **1 bunch** it is automatically 1.00$.
Upon this, we do 7 x 0.57 . The 7 representing the pears and the 0.57 representing the 0.57 cents.
7 x 0.57 = 3.99$
Finally, we do 3 x 0.42. The 3 representing the oranges and the 0.42 representing 42 cents each.
3 x 0.42 = 1.26

The sides of a rectangle are in the ratio 4 : 3. If the perimeter of the rectangle is 210, find its area
Answer:
2700
Step-by-step explanation:
Perimeter of rectangle= 2(length +breadth)
2(length +breadth)= 210
length +breadth= 210 ÷2
length +breadth= 105
Since the length of the rectangle is usually taken to be the longer side of the rectangle,
length: breadth= 4: 3
[tex] \frac{length}{breadth} = \frac{4}{3} [/tex]
[tex]length = \frac{4}{3} (breadth)[/tex]
[tex] \frac{4}{3} (breadth) + breadth = 105[/tex]
[tex] \frac{7}{3} (breadth) = 105[/tex]
breadth
[tex] = 105 \div \frac{7}{3} [/tex]
[tex] = 10 5\times \frac{3}{7} [/tex]
= 45
length +breadth= 105
length +45= 105
length
= 105 -45
= 60
Area of rectangle
= length ×breadth
= 45 ×60
= 2700
4x+15y=17,-x+5y=-13
Solve with substitution and please show steps.
Step-by-step explanation:
4x + 15y = 17
15y = 17 - 4x
y = (17 - 4x)/15
-x + 5y = -13
-x + 5(17 - 4x)/15 = -13
-x + (17 - 4x)/3 = -13
-x - 4x/3 = -13 - 17/3
-7x/3 = -56/3
7x = 56
x = 56/7
x = 8
y = (17 - 4x)/15
y = (17 - 4.8)/15
y = (17 - 32)/15
y = -15/15
y = -1

Answer:
38.4º
Step-by-step explanation:
Use Law of Cosines
c² = a² + b² - 2ab*cosC
12² = 17² + 19² - 2(17)(19)*CosC
Simplify
144 = 289 + 361 - 646 * cosC
144 = 650 - 646 * cosC
Subtract 650 from both sides
-506= -646 * cosC
Divide both sides by -646
0.7832817337 = cosC
Take the arcsin of 0.7832817337
38.4º = C
---------------------------------
Cheaters Solution!!!
Instead of doing the math you could think it through.
Since FD is less than 17
∠E must be less than 45º
So the answer must be A. 38.4º

A painter ordered 3 gallons of red paint for $35 per gallon. He ordered 5 gallons of blue paint for $39 per gallon. What is the total cost of both kinds of paint?
Answer:
$300 is the total cost for both kinds of paint
Step-by-step explanation:
1) Start by breaking down the problem so it was more simple
- Red paint is $35 per gallon; blue is $39 per gallon
2) Since it is by gallon, you will multiply the number of gallons by the cost for each to get the total cost of each
- 35 * 3 = $105 for 3 gallons of red paint
- 39 * 5 = $195 for 5 gallons of blue paint
3) Total cost together; you will add the total cost of red and blue paint together
- 105 + 195 = $300

Line P passes through the point (3,4) and is Perpendicular to the line with equation 3x+2y=8. What is the equation for line p?
Answer:
y = 2/3x + 2
Step-by-step explanation:
3x + 2y = 8
2y = -3x + 8
y = -3/2x + 4
Slope : -3/2
Slope of the perpendicular line: 2/3 (slope of the perpendicular line is opposite reciprocal)

the arithmetic sequence x , x , -3 , 2x what is the value of x
Answer:
x, x, -3, 2x cannot be an arithmetic sequence
Step-by-step explanation:
an arithmetic sequence has a constant difference between subsequent elements. That means
x - x = -3 - x = 2x - (-3)
0 = -3 - x = 2x + 3
and we get:
x = -3 ; from 0 = -3 - x
and
x = -3/2 ; from 0 = 2x + 3
so there is no solution.

what is the slope of the line that goes through points (2, -4) and (-1, 8)
Answer:
Slope = -4
Step-by-step explanation:
Given coordinates,
→ x1 = 2, y1 = -4
→ x2 = -1, y2 = 8
Now we have to,
→ Find the required slope of the line.
Formula we use,
→ Slope(m) = (y2 - y1)/(x2 - x1)
Then the required slope will be,
→ m = (y2 - y1)/(x2 - x1)
→ m = (8 - (-4))/(-1 - 2)
→ m = (8 + 4)/-3
→ m = 12/(-3)
→ m = -12/3
→ [ m = -4 ]
Therefore, the value of m is -4.
Hello !
Answer:
[tex]\Large \boxed{\sf Slope =-4}[/tex]
Step-by-step explanation:
The slope of a line is given by the following formula : [tex]\sf m=\dfrac{y_B-y_A}{x_B-x_A}[/tex] where [tex]\sf x_A[/tex] and [tex]\sf y_A[/tex] are the coordinates of A (same for B).
Given :
[tex]\sf A(2,-4)[/tex][tex]\sf B(-1,8)[/tex]Let's calculate the slope with the previous formula :
[tex]\sf m=\frac{8-(-4)}{-1-2} \\\sf m=\frac{8+4}{-3}\\ \sf m=-\frac{12}{3} \\\boxed{\sf m=-4}[/tex]
