The science department buys the equipment shown in the table they bought all three items this year and how many years will they have had by all three items again

 The Science Department Buys The Equipment Shown In The Table They Bought All Three Items This Year And

Answers

Answer 1
Item                          Time bought
MIcroscopes             Every 5 years
Safety goggles          Every 4 years
Test Tube                  Every 2 years

It would take 20 years for them to buy these three items at the same time.

We simply need to find the LCM or least common multiple of the 3 items using the number of years.

Microscopes - 5 years → 5, 10, 15, 20
Goggles - 4 years → 4, 8, 12, 16, 20
Test tubes - 2 years → 2, 4, 6, 8, 10, 12, 14, 16, 18, 20

The sum of the measures of two complementary angles is 90°. If one angle measures 24° more than twice the measure of the​ other, find the measure of the smaller angle.

Answers

x + y = 90

Let's make 'x' the bigger angle and 'y' the smaller.
X is 24 more than twice y.
x = 24 + 2y

Now plug that into the x of the first equation.
(24 + 2y) + y = 90

Combine like terms.
24 + 3y = 90

Subtract 24 from both sides.
3y = 66

Divide both sides by 3.
y = 22

The measure of the smaller angle is 22°

Which of the following equations has the same solution as m - (-62) = 45?

x + 25 = 8
25 - x = 8
120 - x = 13
120 + x = 13

Answers

Hi Emmaelizabethmot286t

m - (-62) = 45 is the special equation so I'm a solve it and look for the same answer of the other options, so below is my work on how i got the answer of the special equation.

m + 62 = 45
m = 45 - 62
m = -17

The answer would be choice A) x + 25 = 8 and the x in that equation is -17 and -17 + 25 = 8 and that's true, and i figured out the answer by subtracting 25 from both sides and subtracting 8 - 25 so it can be -17.

The sum of 3 consecutive even numbers is 132. What is the third number in this sequence?

Answers

The third number in the sequence is 46, found by adding 4 to the first number, which is 42, as the sum of three consecutive even numbers is 132.

Let's call the three consecutive even numbers x, x + 2, and x + 4.

According to the problem, the sum of these three numbers is 132:

x + (x + 2) + (x + 4) = 132

Now, let's solve for x:

x + x + 2 + x + 4 = 132

Combine like terms:

3x + 6 = 132

Subtract 6 from both sides:

3x = 126

Divide both sides by 3:

x = 42

Now we have the first number in the sequence: x = 42.

To find the third number, we add 4 to x:

[tex]\[ x + 4 = 42 + 4 = 46 \][/tex]

So, the third number in the sequence is [tex]\( \boxed{46} \).[/tex]

packet of sour worms contains four strawberry, four lime, two black currant, two orange sour, and three green apples worms.
What is the probability that Dylan will choose a green apple sour worm?

Answers

The answer would be 3/15. The number of green worms over the total amount of worms.

To calculate the probability of Dylan choosing a green apple sour worm, divide the number of green apple sour worms (3) by the total number of sour worms (15), resulting in a probability of 1/5 or 20%.

The probability that Dylan will choose a green apple sour worm is calculated by dividing the number of green apple sour worms by the total number of sour worms. Dylan has four strawberry, four lime, two black currant, two orange sour, and three green apple worms in his packet. This gives us a total of 15 sour worms.

To calculate the probability, we use the formula P(E) = Number of favorable outcomes / Total number of outcomes.

Therefore, the probability that Dylan picks a green apple sour worm is P(green apple) = Number of green apple worms / Total number of worms = 3 / 15 = 1 / 5.

So, the probability is 0.20 or 20%.

Which equation does the graph below represent? A coordinate grid is shown.

slope = (8 - 0) / (4 - 0) = 8/4 = 2

and since it goes thru the origin, the y int is 0

so ur equation is : y = 2x <==

Answer:

The equation of line is y = 2x.

Step-by-step explanation:

Consider the provided information.

A coordinate grid is shown. The x axis values are from negative 5 to positive 5 in increments of 1 for each grid line, and the y axis values are from negative 10 to positive 10 in increments of 2 for each grid line.

The slope intercept form of an equation of line is: y = mx + c

Where m is the slope and c is the y intercept.

[tex]Slope = m = \frac{Rise}{Run}[/tex]

Increments or decrements in x axis value represent the Run. Increments or decrements in y axis value represent the Rise.

It is given that "y axis values are from negative 10 to positive 10 in increments of 2 for each grid line."

Thus the Rise is 2 unit.

The x axis values are from negative 5 to positive 5 in increments of 1 for each grid line,

Thus the Run is 1 unit.

Hence the slope is: [tex] Slope=m=\frac{Rise}{Run}=2[/tex]

It is given that line passing through (0,0) it means the y intercept is 0.

Now substitute the value of m and y intercept in slope intercept form..

y = 2x + 0

y = 2x

Hence, the equation of line is y = 2x.

For this problem you will make this into a proportion...
The proportion will look like this

 x       3
---- = ----
56      4

The proportion can be solved by dividing 56 by 4 then multiplying by 3 
the answer for x is 42.

Lucas used 42 nails from the box by multiplying the total number of nails, which is 56, by the fraction of nails he used, 3/4 or 0.75.

Lucas bought a box of 56 nails and used 3/4 of the nails. To find how many nails he used, you can multiply the total number of nails by the fraction of nails he used.

Total nails in the box: 56

Fraction used: 3/4

The calculation steps would be:

First, convert the fraction 3/4 to a decimal, which is 0.75.

Then multiply 56 (total number of nails) by 0.75.

Doing the multiplication: 56 × 0.75 = 42.

So, Lucas used 42 nails from the box.

Angela has 24 golf balls and 18 golf clubs. She wants to sell packages of balls and paddles bundled together. What is the greatest number of packages she can sell with no leftover balls and clubs?

Answers

the greatest common factor of 24 and 18 is 6

24/6 = 4 golf balls
18/6 = 3 paddles

so she can sell 6 packages, with each one containing 4 golf balls and 3 paddles.

Final answer:

The greatest number of packages Angela can sell with no leftovers is found by computing the GCD of 24 and 18, which is 6. This results in each package containing 4 golf balls and 3 golf clubs.

Explanation:

The question asks to find the greatest number of packages Angela can sell with no leftover golf balls and clubs. To solve this, we need to find the greatest common divisor (GCD) of 24 golf balls and 18 golf clubs. The GCD of two numbers is the largest number that can divide both of them without leaving a remainder.

To find the GCD of 24 and 18, we list the factors of each number:

Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24 Factors of 18: 1, 2, 3, 6, 9, 18

The largest factor that both lists share is 6. Therefore, the greatest number of packages Angela can sell with no leftovers is 6. This means each package would contain 4 golf balls (24 ÷ 6) and 3 golf clubs (18 ÷ 6).

Answers

7q = 49......division property of equality....divide both sides by 7
q = 49/7
q = 7

Answer:

division property of equality

Step-by-step explanation:

7q= 49

To solve this equation we  need to get 'q' alone

In order to get 'q' alone, we need to remove 7 from 'q'

Here 7 is multiplied with 'q'

To remove any number we always do opposite operation

Opposite operation of multiplication is division

So we divide both sides by 7

q= 7
