A pear costs $0.40 and an Apple costs $0.25. What is the total cost of p pear and a apples?
Answer:
$0.65
Step-by-step explanation:
$0.40 + $0.25 = $0.65
Answer:
0.40p+0.25a=cost
Step-by-step explanation:
Considering that every apple costs 25 cents and every pear costs 40 cents, you would multiply how many apples and or pears there are by how much they are worth and then add it to get the total cost. Due to there not being a specific total or how many apples and/or pears there are, it currently can't be solved.
how do we calculate percentage that were increase
Answer:
here you go
Step-by-step explanation:
First: work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number.
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100.

Complete the square for each expression. Write the resulting expression as a binomial squared. x^2-10x+_____
Answer:
[tex](x-5)^{2}[/tex]
Step-by-step explanation:
[tex]ax^{2} + bx + c[/tex]
Take the value for b, divide it by 2 and square it to get the value for c.
In this case, b = -10.
- 10 ÷ 2 = -5
-5^2 = 25
So x^2 - 10x +25 is your quadratic equation which is equal to
[tex](x-5)^{2}[/tex]
An angle is a right angle if it measures 30°.
Write the statement in if-then form.
Then identify the hypothesis and conclusion of the resulting conditional statement.
Finally, determine the truth value of the statement.
2. Write your own statement in if-then form. Then identify the hypothesis and conclusion of the resulting conditional statement.
Determine the truth value of the statement.
Write it’s converse to see if it’s true. If the converse is true, write a bi-conditional statement.
Answer:
1) If the measure of an angle is 30°, then it is a right angle
2) The hypothesis = The measure of an angle is 30°
The conclusion = It is a right angle
3) The statement is false
Step-by-step explanation:
1) The information given is that an angle is a right angle if it measures 30°
The statement in the if-then form can be presented as follows;
If the measure of an angle is 30°, then it is a right angle
2) The hypothesis = The measure of an angle is 30°
The conclusion = It is a right angle
3) Given that a right angle measures 90°, the compound statement; "If the measure of an angle is 30°, then it is a right angle" is false.
You want to determine the probability that in a litter of 5 kittens, there will be more female than male kittens. Which describes one trial of a simulation you could use to model this problem?
The trial of stimulation that can model the probability of the gender of the kittens is tossing a coin five times and count the number of heads.
What is probability?Probability simply means the chance of the occurrence of an event. It's the numerical description of how likely an event will occur.
In this case, from the complete question, the trial of stimulation that can model the probability is to toss a coin five times and count the number of heads. The gender of the kittens can be allocated to the head or tail of the coin.
This is important to determine the probability that in a litter of 5 kittens, there will be more female than male kittens.

3-2r + 1 - 13
Step-by-step explanation:
3-2r + 1 - 13
Answers:
Compound inequality: 1 < x < 6Graph: Open hole at 1 and 6, shading in between (see diagram below)Interval notation: (1,6)=============================================
Work Shown:
3 < 2x+1 < 13
3-1 < 2x+1-1 < 13-1 .... subtract 1 from all sides
2 < 2x < 12
2/2 < 2x/2 < 12/2 ... divide both sides by 2
1 < x < 6
The value of x is between 1 and 6, excluding both endpoints.
Since we exclude both endpoints, the graph will have open holes at 1 and 6 on the number line. The shading is between the open holes. The graph is below.
Converting 1 < x <6 to interval notation leads to (1, 6)
The curved parenthesis in interval notation indicate "exclude the endpoint".

What is 1/4 of a 3.5 radius of a circle?
Answer:
Let us divide the circle into 4 equal parts because they have told that 1/4 th part so there are 4 equal parts because,fractions represent equal parts of a whole or a collection.
Let us take a circle with centre 'O'
Now, the 1/4th part of circle is a sector with angle 90° & radius 3.5cm
We can find the area of sector in 2 methods
Method 1 :
Formula :
Here , r is radius & θ is the angle in sector where θ is measured in degrees
Hence , area of sector = 9.6cm²
Method 2 :
Formula:
Here , r is radius & θ is angle in sector where θ is measured in radians
First we have to convert 90° into radians
We know that π radians = 180°
90 ° = π/2 radians
Substituting
Hence , area of sector = 9.6 cm²

Answer:
m = 5
n = 5
Step-by-step explanation:
Note that the ∑ of the interior angles of a triangle = 180°.
A square for one of the angles constitute as 90°.
This means that this is a isosceles triangle.
Note that for isosceles triangles, the sides will follow the rule of 1 , 1 , √2, in which √2 is the hypotenuse.
The hypotenuse is the side opposite of the greatest angle measurement. It is given that the hypotenuse for the given triangle is 5√2. Divide √2 from the given measurement to get the measurements for the legs:
[tex]\frac{5\sqrt{2} }{\sqrt{2} } = 5[/tex]
Again, as it is a isosceles triangle, the two sides will share the same measurement.
m = 5
n = 5

Work out the probability that he chooses two different types of biscuits.
Answer:
There are two patterns to chose two different biscuits; a digestive then a chocolate or a chocolate and then a digestive.
The probability of choosing a digestive then a chocolate is as follows:

What is the width of the prism?
2 ft
w
4 ft
Volume = 24 cubic feet
Answer:
3 ft
Step-by-step explanation:
(I assumed that this was a rectangular prism based on the dimensions given, but do correct me if I assumed incorrectly.)
The formula for finding the volume of a rectangular prism is: [tex]V=w*h*l[/tex]
In this case, we already know that the volume of the prism is 24, so we can plug 24 in for V:
[tex]24=w*h*l[/tex]
We also already know the height and the length because they gave it to us, so we can plug it in as follows:
[tex]24=w*2*4[/tex]
Then we can multiply 2 and 4 on the right side:
[tex]24=w*8[/tex]
Then, to get the w alone, we can divide by 8 on both sides:
[tex]3=w[/tex]
Now that gives us that the width of the rectangular prism is 3ft.

I immediately exited the freeway and headed back in the opposite direction toward my house. However, 3/4th of the way back, I ran out of gas and my car stopped on the side of the freeway. What is my displacement?

Using the fact that cos(52) = 0.6157, find the measure of angle B if sin(B) = 0.6157.
===============================================
Work Shown:
If cos(A) = sin(B), then A+B = 90, where A & B are both acute angles in degree form.
In this case, A = 52, so,
A+B = 90
B = 90-A
B = 90-52
B = 38
Telling us that
cos(A) = cos(52) = 0.6157
sin(B) = sin(38) = 0.6157
cos(52) = sin(38)

If Addison wants to pay off her balance in 24 months, determine the monthly payments she would need to make. Choose the following modification with the least cuts to her current expenses that will allow Addison to pay off her balance in 24 months. Income Wages $2,278. 00 Expenses Rent $950. 00 Utilities $232. 45 Food/Clothes $445. 00 Entertainment $270. 00 Car $200. 00 Credit Card $86. 25 Cell Phone $77. 89 Net Income $16. 41 a. Addison can eliminate $73 from Food/Clothes and $100 from Entertainment. B. Addison can eliminate $45 from Food/Clothes and $41 from Entertainment. C. Addison can eliminate $25 from Food/Clothes and $22 from Entertainment. D. The minimum payment is enough to pay off the balance within 24 months.
Addison needs to cut $45 from Food/Clothes and $41 from Entertainment, to pay the revised monthly payment.
It is given that
Addison has a balance of $3,450 on her credit card.
APR = 18%
Current monthly payment = $86.25
She wants to choose a monthly payment for 24 months.
So for 24 months,
A revised monthly payment using formula,
[tex]M = \frac{P.\frac{R}{12}. (1+\frac{R}{12} )^N }{(1+\frac{R}{12})N -1}[/tex]
R = 0.18
P = 3450
N = 24
Revised montly payment M = $172.24
Current monthly payment = $86.25
Difference = $86
So, she needs to cut the expenses by $86
If she cut $45 from Food/Clothes and $41 from Entertainment, she can easily pay the revised monthly payment.
Therefore, Addison needs to cut $45 from Food/Clothes and $41 from Entertainment, to pay the revised monthly payment.
