Son of Hannah‘s plants need water every day some need water every other day and some need water every third day if she what is an all today how many days will it be before she waters them all again
Answer:
3 days
Step-by-step explanation:
Some of Hannah‘s plants need water every 1 day.
Some need water every third(3) day.
If she waters them all today, we are to determine when next she will waters them all again.
To do this, we find the lowest common multiple of 1 and 3.
L.C.M of 1 and 3=3
Therefore, in 3 days time, she will water them all again.
Solve the equation. \dfrac18 + c = \dfrac45 8 1 +c= 5 4 start fraction, 1, divided by, 8, end fraction, plus, c, equals, start fraction, 4, divided by, 5, end fraction c=c=c, equals
Answer:
[tex]c=\dfrac{27}{40}\\[/tex]
Step-by-step explanation:
We are required to solve for c in the equation: [tex]\dfrac{1}{8}+c= \dfrac{4}{5}[/tex]
Step 1: Collect like terms
[tex]\dfrac{1}{8}+c= \dfrac{4}{5}\\c= \dfrac{4}{5}-\dfrac{1}{8}[/tex]
Step 2: Find the Lowest Common Multiple of the denominators
LCM of 8 and 5 is 40
Step 3: Multiply all through by 40
[tex]40c= \dfrac{4}{5}*40-\dfrac{1}{8}*40[/tex]
Step 4: Simplify
40c=32-5
40c=27
Step 5: Divide both sides by 40 and simplify if possible.

In a survey of 2 comma 3002,300 people who owned a certain type of car, 1 comma 2651,265 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
55% of the people surveyed were satisfied with the car
Step-by-step explanation:
The proportion of people surveyed who were satisfied with the car is the number of people who said they would buy that type of car again divided by the total number of people survied.
The percentage is the proportion multiplied by 100.
We have that:
2,300 people surveyed
1,265 said they would buy that type of car again.
1265/2300 = 0.55
0.55*100 = 55%
55% of the people surveyed were satisfied with the car

BD−→− bisects ∠ABC such that m∠ABD = (4x−5)∘ and m∠DBC = (3x+2)∘.
Find m∠ABC.
m∠ABC = ∘
Answer:
[tex]\angle ABC=(46)^{\circ}[/tex]
Step-by-step explanation:
Given: BD bisects [tex]\angle ABC[/tex]
[tex]\angle ABD=(4x-5)^{\circ}\\\angle DBC=(3x+2)^{\circ}[/tex]
To find: [tex]\angle ABC[/tex]
Solution:
A bisector of an angle divides it into angles of equal measures.
As BD bisects [tex]\angle ABC[/tex], [tex]\angle ABD=\angle DBC[/tex]
Put [tex]\angle ABD=(4x-5)^{\circ}\,,\,\angle DBC=(3x+2)^{\circ}[/tex]
[tex]\angle ABD=\angle DBC\\(4x-5)^{\circ}=(3x+2)^{\circ}\\4x-3x=2+5\\x=7^{\circ}[/tex]
So,
[tex]\angle ABD=(4x-5)^{\circ}=(4(7)-5)^{\circ}=(28-5)^{\circ}=(23)^{\circ}\\\angle DBC=(3x+2)^{\circ}=(3(7)+2)^{\circ}=(21+2)^{\circ}=(23)^{\circ}[/tex]
[tex]\angle ABC=\angle ABD+\angle DBC\\=(23)^{\circ}+(23)^{\circ}\\=(46)^{\circ}[/tex]
A bisector divides lines, angles and shapes into equal segments
The measure of angle ABC is 46 degrees
The given parameters are:
m∠ABD = (4x−5)∘ m∠DBC = (3x+2)∘Given that line BD is the bisector of angle ABC, it means that:
[tex]\angle ABD = \angle DBC[/tex]
and
[tex]\angle ABC = 2\times \angle ABD[/tex]
So, we have:
[tex]4x - 5 = 3x +2[/tex]
Collect like terms
[tex]4x - 3x = 5 +2[/tex]
Evaluate like terms
[tex]x = 7[/tex]
Recall that
[tex]\angle ABC = 2\times \angle ABD[/tex]
So, we have:
[tex]\angle ABC = 2 \times (4x - 5)[/tex]
Substitute 7 for x
[tex]\angle ABC = 2 \times (4\times 7 - 5)[/tex]
[tex]\angle ABC = 2 \times (28 - 5)[/tex]
[tex]\angle ABC = 2 \times 23[/tex]
[tex]\angle ABC = 46[/tex]
Hence, the measure of angle ABC is 46 degrees

You are making a colorful cake for a birthday party and need to use 4 drops of food coloring for every 5 ounces of icing. How many drops of food coloring do you need if
you are using 30 ounces oficing?
Answer:
24 drops of food coloring
Step-by-step explanation:
First, since there are 30 ounces, divide by 5, because there are 4 drops in every 5 ounces of icing. Since 30÷5=6, You have to multiply it by 4 to get 24. You multiply by 4 because there are 4 drops in 5 ounces of icing.
24 drops of food colouring are needed if you are using 30 ounces oficing.

Bob is performing an experiment to learn more about probability. He has a box of pink, yellow, blue, and white ribbons. He randomly picks a ribbon from the box and then replaces it. He does this 100 times. The table shows the number of times he picks a ribbon of each color. Ribbon Color Number of Times Picked pink 10 yellow 20 blue 40 white 30 The relative frequency of picking a pink ribbon is . The relative frequency of picking a white ribbon is . It is most likely that the number of ribbons in the box is the highest. It is most likely that the number of ribbons in the box is the lowest
Answer:
1. 0.1
2. 0.3
3. blue
4. pink.
Step-by-step explanation:
Got it right, hope this helps! :)
The blue ribbon was picked the most with a relative frequency of 40%, which means it is most likely that there are more blue ribbons in the box than the other colors.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The relative frequency of picking a pink ribbon is found by dividing the number of times a pink ribbon was picked by the total number of times Bob picked a ribbon:
Relative frequency of pink ribbon = 10/100 = 0.1 or 10%
Similarly, the relative frequency of picking a white ribbon is:
Relative frequency of white ribbon = 30/100 = 0.3 or 30%
To determine which ribbon color is most likely to be the highest or lowest, we can compare the relative frequencies.
The blue ribbon was picked the most with a relative frequency of 40%, which means it is most likely that there are more blue ribbons in the box than the other colors.
Conversely, the pink ribbon was picked the least with a relative frequency of 10%, which means it is most likely that there are fewer pink ribbons in the box than the other colors.
Hence, the blue ribbon was picked the most with a relative frequency of 40%, which means it is most likely that there are more blue ribbons in the box than the other colors.

The rail fare £16.25 is increased by 5%; how much does the fare now co st?
Given our current rail fare of £16.25, we are looking for the price of the rail fare after a 5% increase.
To find the value of a 5% increase, we can multiply the rail fare by 1.05 since it is 5% added to the total value.
Or, we can multiply the rail fare by 5 and then divide by 100 to get how much will be added onto it.
Let's do both of them:
Increase: 5%
Equation: 1.05 x 16.25
1.05 x 16.25 = 17.06 rounded to the nearest cent
Rail Fare after 5% increase: £17.06
Increase: 5%
Equation: (5 x 16.25)/100
81.25/100 = .81 rounded to nearest cent
Then, we add them together.
16.25 + 81 = 17.06
Rail Fare after 5% increase: £17.06

Convert 50°C to °F.
10°F
20°F
122°F
132°F
The temperature in degree Fahrenheit is (c) 122
The function is given as:
[tex]C = \frac 59(F - 32)[/tex]
When the temperature is 50 degrees Celsius, it means that:
C =50
Substitute 50 for C in [tex]C = \frac 59(F - 32)[/tex]
[tex]50 = \frac 59(F - 32)[/tex]
Multiply through by 9
[tex]450 = 5(F - 32)[/tex]
Divide both sides by 5
[tex]90 = F - 32[/tex]
Add 32 to both sides
[tex]F = 90 +32[/tex]
