A farmer sells 9.6 kilograms of apples and pears at the farmer's market. 3/4 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market (i need it expressed in fraction and decimal form please!! im almost out of time to answer :<) please answer asap!!
Answer:
Decimal form = 2.4 / Fraction form = 1/4
Step-by-step explanation:
We know that the farmer sold 9.6 kilograms of apples and pears where 3/4 of that weight was apples. That means that 1/4 of the 9.6 kilograms were pears. Lets divide 9.6 by 1/4 to get our answer.
9.6 / 1/4 = 2.4
Decimal form = 2.4
Fraction form = 1/4

Write three equations whose solution is x=3.5
To write three equations whose solution is x=3.5, you can use different algebraic expressions. Three examples are x + 2 = 5.5, (2x - 5) / 3 = 1.8333, and x^2 - 12x + 42 = 0.
Explanation:To write three equations whose solution is x=3.5, we can use different algebraic expressions to represent the same value. Here are three examples:
x + 2 = 5.5 - In this equation, if we substitute x with 3.5, we get 3.5 + 2 = 5.5, which is true.(2x - 5) / 3 = 1.8333 - If we plug in x=3.5, we get (2(3.5) - 5) / 3 = 1.8333, which is true.x^2 - 12x + 42 = 0 - If we solve this quadratic equation, we find x=3.5 as one of the solutions.Learn more about Equations with a specified solution here:https://brainly.com/question/34695214

Step-by-step explanation:
Recall,
1 centiliter = 10 milliliters
So, 78 centiliters = 78 * 10 milliliters
= 780 milliliters
The Smiths spend 6% of their budget on entertainment. Their total budget this year is $3,000 more than last year, and this year they plan to spend $2,580 on entertainment. What was their total budget last year?
Answer: Their total budget last year was $40,000.
Step-by-step explanation:
Given : The Smiths spend 6% of their budget on entertainment.
i.e. , The money they spend on entertainment = 0.06 x ( Total budget)
{ 6% is converted to 0.06 , when we divide it by 100 to remove percentage)
Since , this year they plan to spend $2,580 on entertainment.
i.e. 0.06 x ( Total budget ) = $2,580
On dividing both sides by 0.06 , we get
( Total budget ) = $2,580 ÷ 0.06
= $43,000
Thus , their total budget for this year = $43,000
Also, Their total budget this year is $3,000 more than last year.
Therefore , their last year total budget = ( Total budget this year ) - $3000
= $43,000 - $3000
= $40,000
Hence, their total budget last year was $40,000.

Answer:
3+sqrt(13/2)
3-sqrt(13/2)

Divide each side by 2
2/2 (x-3) ^2 =13/2
(x-3) ^2 =13/2
Take the square root of each side
sqrt((x-3) ^2) =±sqrt(13/2)

mike made a fruit basket of the total fruit 5 were apples 5/8 were bananas and 1/4 were oranges,how many pieces of fruit did mike use?
Answer: 5 7/8
Step-by-step explanation: 5 + 5/8 + 1/4= 5 7/8
The total number of pieces of fruit Mike used is [tex]40.[/tex]
Based on the information given.
1. Let [tex]\( T \)[/tex] be the total number of pieces of fruit.
2. Mike has [tex]5[/tex] apples.
3. [tex]\(\frac{5}{8}T\)[/tex] are bananas.
4. [tex]\(\frac{1}{4}T\)[/tex] are oranges.
Since these fractions represent parts of the total fruit, the sum of the apples, bananas, and oranges should equal the total number of pieces of fruit:
[tex]\[5 + \frac{5}{8}T + \frac{1}{4}T = T\][/tex]
Rewrite the equation with all terms having the same denominator:
[tex]\[5 + \frac{5}{8}T + \frac{2}{8}T = T\][/tex]
Combine the fractions on the left side:
[tex]\[5 + \frac{7}{8}T = T\][/tex]
Subtract [tex]\(\frac{7}{8}T\)[/tex] from both sides to isolate the constant term:
[tex]\[5 = T - \frac{7}{8}T\][/tex]
[tex]\[5 = \frac{1}{8}T\][/tex]
Multiply both sides by [tex]8[/tex] to solve for [tex]\( T \)[/tex]
[tex]\[5 \times 8 = T\][/tex]
[tex]\[T = 40\][/tex]

Stephanie works at a store that sells clothing accessories. The supply
function for scarves is P = Q-12, where Pis the price and Q is the quantity of
scarves. If Stephanie sells the scarves for $11 apiece, how many scarves can
the store make?
O
A. 34 scarves
O B. 12 scarves
O c. 23 scarves
O D. 11 marves
Answer:
23 scarves
Step-by-step explanation:
To solve this you need to plug the price Stephanie sells the scarves for, $11, in for P in the equation and solve for Q.
11 = Q - 12Add 12 to both sides: 23 = QThe quantity she can make is 23 scarves.
Write the point-slope form of the equation of the line that passes through the points (6, 6) and (-6, 1). Include your work in your final answer. Type your answer in the box provided to submit your solution.
The slope of the lines passing through given points is [tex]\frac{5}{12}[/tex].
Step-by-step explanation:
Given,
The given two points are (6,6) and (-6,1).
To find the slope of the line passing through the points.
Formula
The slope of the line passing through ([tex]x_{1} ,y_{1}[/tex]) and ([tex]x_{2} ,y_{2}[/tex]) is [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
Now,
Putting, [tex]x_{1}=6, y_{1}=6, x_{2}=-6, y_{2}= 1[/tex] we get,
Slope = [tex]\frac{1-6}{-6-6}[/tex] = [tex]\frac{-5}{-12}[/tex] = [tex]\frac{5}{12}[/tex]
Hence,
The slope of the lines passing through given points is [tex]\frac{5}{12}[/tex].

Newton’s Law of Cooling expresses the relationship between the temperature of a cooling object y and the time t elapsed since cooling began, in minutes. This relationship is given by y=ae where c is the temperature of the medium surrounding the cooling object, a is the difference between the initial temperature of the object and the surrounding temperature, and k is a constant related to the cooling object. -The initial temperature of a liquid is When it is removed from the heat, the temperature in the room is . For this object, Use Newton’s Law of Cooling to find the temperature of the liquid after 15 minutes.
Answer:
79 °F
Step-by-step explanation:
Newton’s Law of Cooling:
[tex]y = ae^{-kt} + c[/tex]
Data
The initial temperature of a liquid is 160 °F The temperature in the room (c) is 76 °FThen a = 160 - 76 = 84 °Fk = 0.23t = 15 minutesReplacing into the equation:

Q4. The dimensions of a rectangular sheet of metal are 9.96m by 5.08 m. Find
a. the perimeter of the metal, correct to 1 significant figure
b. the area of the metal, correct to the nearest 0.1 m2
Answer:
a) 30m
b) 50.6m²
Step-by-step explanation:
Perimeter = 2(length + width)
= 2(9.96 + 5.08)
= 30.08 m
Area = length × width
9.96 × 5.08
50.5968 m²
Tyrone's age is 2 years less than 4 times his younger sister's age. If his younger sister's age is b years, which of the following expressions best shows Tyrone's age?
4b b − 2 2b − 4 4b − 2
Answer:
Four times his sister's age would be 4b. his age is two years less, so we need to subtract 2.
put together, this is 4b - 2.
Answer:
Your answer will be 4b - 2

If necessary, combine like terms.
(3+4.)(3 - 4x) =
Answer:
-16x^2 +9
Step-by-step explanation:
To start this problem I would rearrange so that the terms with the x's come first. Making it look like this
(4x+3)(-4x+3)
Now you take the 4x and distribute it to the -4x and the 3.
-16x^2+12x This is the first part
Take the 3 and distribute it to the -4x and the 3 as well.
-12x+9
All you do now is combine the twoso you'd have
-16x^2 +12x -12x +9 Notice there are two terms that have a regular x with no exponent. This means you can combine them to simplify further.
-12x+12x=0 So you no longer have to include this term in your answer.
-16x^2+9 Would then be your final answer.
The measure of arc XZ is 32°.
What is the measure of XYZ?
A. 32°
B. 64°
C. 148°
D. 16°
Given:
Measure of arc XZ = 32°
To find:
The measure of XYZ
Solution:
The measure of inscribed angle is half of the measure of the intercepted arc.
[tex]$\Rightarrow m\angle XYZ = \frac{1}{2}m(ar XZ)[/tex]
[tex]$\Rightarrow 32^\circ = \frac{1}{2}m(ar XZ)[/tex]
Multiply by 2 on both sides.
[tex]$\Rightarrow 2\times 32^\circ =2\times \frac{1}{2}m(ar XZ)[/tex]
[tex]$\Rightarrow 64^\circ =m(ar XZ)[/tex]
The measure of angle XYZ is 64°.

Answer:
20 m.
Step-by-step explanation:
Formula for rhombus: base x height.
Base: 8
Height: 2.5
2.5 x 8 = 20.
Tip: Usually when finding the area of a rhombus there is another length (in this scenario, 4) to try to fool or trick you. It's the length of the slanted side to the right. A rhombus is a square or rectangle when you take the triangle and piece it into the slanted area, so even though it looks like a complicated parallelogram it really isn't.

7. we can assume the height of the radio tower to be x. We're given with its shadow,the height of the person and also their shadow. Since we have 3 known values and an unknown, we can make a proportion comparing the tower's height to the height of the person.
∴ 6/10 = x/ 400
⇒ x= (6 * 400)/10 = 240 feet.
8. The question is similar to the above question where again we have 3 knowns and one unknown. Let us assume the length to be x. We'll again compare the length of the two photographs and make it as a proportion.
∴ 4/6 = x/10
⇒ x = (4 * 10)/6 = 6.7 in
