Answer:
Option D
Step-by-step explanation:
Given the following question:
[tex]12 \frac{3}{4} \times3[/tex]
In order to find the answer, we have to convert the mixed number and then multiply by three, since how Eva needs triple the amount for today's baking.
[tex]12 \frac{3}{4} \times3[/tex]
[tex]12\frac{3}{4} =4\times12=48+3=51=\frac{51}{4}[/tex]
[tex]3=\frac{3}{1}[/tex]
[tex]\frac{51}{4} \times\frac{3}{1}[/tex]
[tex]51\times3=153[/tex]
[tex]4\times1=4[/tex]
[tex]=\frac{153}{4}[/tex]
Convert the improper fraction back into a mixed number:
[tex]\frac{153}{4}[/tex]
[tex]\frac{153}{4} =153\div4=38\frac{1}{4}[/tex]
[tex]=38\frac{1}{4}[/tex]
Which means Eva needs "38 1/4 pounds of flour" or option D for today's baking.
Mary has 12 marbles 3/12 of the marbles are yellow 2/12 of the Marvels are blue The rest of the marbles are green How many marbles are green Explain how you know
Answer: 7 marbles are green.
Step-by-step explanation:
Since we have 12 marbles in total, 12/12 = 1. Since the fractions have denominators of 12 as well, we can easily tell there are 3 yellow marbles (3/12) and there are 2 blue marbles (2/12).
Lastly, we need to find how many are green. We can subtract the yellow and blue marbles from the total of 12 marbles.
12 - (3 + 2)
12 - (5)
7 marbles are green.
Answer:
Seven marbles are green.
Step-by-step explanation:
you have a total of 12 marbles.
12-3 (yellow) = 9
9-2 (blue) = 7
3 (yellow) + 2 (blue) = 5
12 (total) - 5 (yellow and blue) = 7

Answer:
the parallel line is y = 8x + 6
Step-by-step explanation:
so to solve for a parallel line we already know that the slopes are the same. so rn we can write:
y = 8x + b
but since we do not know the y-intercept we can use the points given to find it
we substitute them
-2 = 8(-1) + b
-2 = -8 + b
b = 6
the parallel line is y = 8x + 6
heres a pic if you dont believe me
Slope=m=8

A triangle has two sides of length 2 and 14. What is the largest possible whole-number length for the third side?
Answer:
15
Step-by-step explanation:
Note that;
The sum of the lengths of 2 sides of a triangle must be greater than but not equal to the length of the third side.
As well as, the third side must be longer than the difference between the greater and the lesser of the other two sides
Given;
First side of the triangle = 17
Second side of the triangle = 2
Let us assume the third side of the triangle = T
Now, In any given triangle:
"Sum of any two sides of a triangle is strictly greater than the third side."
⇒ Sum of first side + Sum of second side > Third Side
or, m < 2 + 14
or, m < 16
Hence, the largest possible value for m = 15

A rectangular pool is 6 feet long and 5 feet wide. It is filled to a depth of 2 Teet. A cubic footof water is about 7.5 gallons. If the pool can be filled at a rate of about 10 gallons per minute,now long will it take to fill the pool to a depth of 2 feet? Explain your reasoning.
*QUICK*
Answer:
450 minutes
Step-by-step explanation:
First, let's calculate the volume of the pool when filled. Volume will be: (length x width x height).
Volume = 6' x 5' x 2 ' = 60 ft^3
1 ft^3 of water occupies 7.5 gallons. That's a conversion factor for water: (7.5 gal)/(1 ft^3).
The total gallons of water in a filled pool would be:\
(60 ft^3)*((7.5 gal)/(1 ft^3)) = 4500 gallons
At a rate of 10 gallons/min, it would take:
(4500 gallons)/(10 gallons/min) = 450 minutes, or 450/60 = 7.5 hours

The circumference of a circle is its perimeter.
We can solve for the circumference using the following formula:

The radius of the circle is 14 cmPlug the given information into the formula for circumference:
[tex]C=2\pi r\\C=2\pi (14)\\C=28\pi[/tex]
Therefore, the circumference of the circle is 28π cm.
Part BReplace π with [tex]\dfrac{22}{7}[/tex]:
[tex]C=28\pi\\\\C=28*\dfrac{22}{7}\\\\C=4*22\\C=88[/tex]

The length of a rectangle is 10 m greater than the width, and the area is 600 sq. m. Find the dimensions
Step-by-step explanation:
l = length
w = width
l = w + 10
l×w = 600 m²
now, using the identity of the first equation in the second equation
(w + 10)×w = 600
w² + 10w = 600
w² + 10w - 600 = 0
the general solution to such a squared equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
x = w
a = 1
b = 10
c = -600
w = (-10 ± sqrt(10² - 4×1×-600))/(2×1) =
= (-10 ± sqrt(100 + 2400))/2 = (-10 ± sqrt(2500))/2 =
= (-10 ± 50)/2 = -5 ± 25
w1 = -5 + 25 = 20 m
w2 = -5 - 25 = -30
the negative solution does not make any sense for side lengths. so, the only valid solution is w = 20 m.
l = w + 10 = 20 + 10 = 30 m
the length is 30 m.
the width is 20 m.

[tex]log16^{n} =log\frac{1}{64}[/tex]
Answer:
x = -3/2
Step-by-step explanation:
1. Cancel out log from both sides -> 16^n = 1/64
2. Log16 both sides to isolate n -> log16(16^n) = log16(1/64) -> n = log16(1/64)
log16(1/64) = -3/2

Mr. Hayden's Bible class collected $11
in coins for a needy family. They col-
lected twice as many quarters as dimes
and 12 more nickels than dimes. How
many of each coin did the class collect?
This is the only way I can think of this mathematically. This took a good 20 minutes for me. You need to guess and check. Like try 17 quarters, 50 nickels, and 37 dimes etc. until you get 11.00. My numbers are mathematically correct but we both know you cant have 18.909 quarters so. lol
Answer:
Quarters: 18.909
Nickels: 49.818
Dimes: 37.818
Somewhere around those numbers.
Step-by-step explanation:
$11.00 total in coins
Nickel = $0.05
Dime = $0.10
Quarter = $0.25
(n*0.05) + (d*0.10) + (q*0.25)
Solve the equation for q.
[tex]q=\frac{1}{2} d[/tex]
(n*0.05) + (d*0.10) +( [tex]\frac{1}{2} d[/tex] *0.25)
Simplify the expression.
9d + 2n = 440
d - n = -12
Multiply both sides of the equation by -9.
-9d + 9n = 108
9d + 2n = 440
Sum the equations vertically to eliminate at least one variable.
11n = 548
[tex]n=\frac{548}{11}[/tex]
Substitute the given value of n into the equation d - n = -12
[tex]d-\frac{548}{11} =-12[/tex]
[tex]d=\frac{416}{11}[/tex]
Substitute the given value of n into the equation [tex]q=\frac{1}{2} d[/tex]
[tex]q=\frac{1}{2} *\frac{416}{11}[/tex]
[tex]q=\frac{208}{11}[/tex]
Finally
[tex]d=\frac{416}{11}[/tex] d = 37.818

Trish is going to camp for 50 days on 15 July 2022. Calculate the date when he will return from camp
Answer:
Trish is going to return from camp September 3rd, 2022.
Step-by-step explanation:
Okay! note: (There are 31 days in july)
July 15th+10 days=July 25th
July 25+6=July 31st
July 31st+1 day= August 1st
(17 days done so far)
August 1st+30 days=August 31st
(47 days done)
August 31st+1 day=September 1st
September 1st+2 days= September 3rd
I got the answer by breaking up the 50 days into smaller parts and adding them. Make sure you know how many days are in the months so you don't get too confused.

Find the equation of the line through point (10,4) and parallel to 3x+5y=8. Use a slash ("/") for fractions (e.g. 1/2 for 12). DO not include spaces in your answers.
Answer:
3x + 5y = 50
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
3x + 5y = 8 ( subtract 3x from both sides )
5y = - 3x + 8 ( divide terms by 5 )
y = - [tex]\frac{3}{5}[/tex] x + [tex]\frac{8}{5}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{3}{5}[/tex]
Parallel lines have equal slopes , then
y = - [tex]\frac{3}{5}[/tex] x + c ← is the partial equation
to fid c substitute (10, 4 ) into the partial equation
4 = - 6 + c ⇒ c = 4 + 6 = 10
y = - [tex]\frac{3}{5}[/tex] x + 10 ← equation of parallel line in slope- intercept form
multiply through by 5 to clear the fraction
5y = - 3x + 50 ( add 3x to both sides )
3x + 5y = 50 ← equation of parallel line in standard form
Solution:
Step-1: Convert the equation of the line into slope intercept form.
3x + 5y = 8=> 5y = -3x + 8=> y = -3x/5 + 8/5In this case, the slope we obtained is -3/5, which is -0.6. Let's use point slope form to find the original equation.
Step-2: Use point slope form.
y - y₁ = m(x - x₁)=> y - 4 = -0.6(x - 10)=> y - 4 = -0.6x + 6=> y = -0.6x + 10Solve in simplest radical form

A vehicle is randomly selected. Let S be the event that
the vehicle is an SUV and let D be the event that the vehicle has 4WD. What is the value of P(S and Dc)?
O 0.04
O 0.23
O 0.38
O 0.41
Assuming S is the event that the vehicle is an SUV the value of P(S and D) is:0.38.
ProbabilityNumber of vehicles=165
Total number of SUV=10+23+52=85
Hence:
The event that vehicle is SUV(S)=85
The event that vehicle is 4WD(D)=23
Value of P(S and D)=85-23/165
Value of P(S and D)=62/165

James has $325 in his savings account. He spends $28 a week. How many, w, weeks until he has $157 left in his account?
Answer:
6 weeks
Step-by-step explanation:
Total savings= $325
For every week, his total savings decrease by $28.
Let's form an expression for the amount of money left in his account after w weeks.
325 -28w= 157
28w= 325 -157
28w= 168
Divide by 28 on both sides:
w= 168 ÷28
w= 6
Thus, there are 6 weeks until he has $157.
