The gas in Dads car holds 12 gallons. Athe gas tank in Moms truck holds 50% more than that. How much gas does the truck's tank hold? Explain why this situation can be represented by the equation. Make sure that you explain what t represents.
Answer:
18 gallons
Step-by-step explanation:
Step one:
given data
The gas in Dad's car holds 12 gallons
the gas tank in Moms truck holds 50% more than that in Dad's car
Hence 50% of 12 is
=50/100*12
=0.5*12
= 6 gallons
We are told that the gas tank in Moms truck holds 50% more than that in Dad's car
Therefore Mum's car will hold
=12+6
=18 gallons

What is the measure of angle RST?
a. 87
b. 131
c. 93
d. 90
Option c. 93°.
Alright, so in this one um the angle um so uh this angle right here, let's see right here, right which these two angles these angles are going to be equal because those are vertical angles. So these this angle is equal to um So angle P. S. T. Is equal to one half the sum of those two arcs added together, so 43 plus 1 31 So one half of Uh was that 1 74, So 1 74, divide by two 87. So this is 87 and then you take 18687 And you get 93.
What is the measure of ∠ RST?Triangle RST is isosceles means that two of its angles are equal. (1) The measure of angle T is 100 degrees --> since no other angle can be equal to 100 degrees (because in this case, the sum of the angles will be more than 180 degrees) than the other two angles, R and S, are equal: R=(180-100)/2=40.

Step-by-step explanation:
Marla bought 1250 pounds of pecans at $1.29 per pound and another 1500 pounds of pecans at $1.59 per pound. She sold all the pecans for \$6.75 per kilogram. After paying her suppliers, how much money did she make?
Answer:
After paying her suppliers, she made $4,575.
Step-by-step explanation:
First, you have to multiply the number of pounds purchased for the price:
$1.29*1250=$1,612.5
$1.50*1500=$2,250
Now, you can add both amounts to find the total cost:
$1,612.5+$2,250=$3,862.5
Now, you have to find the total amount of lb purchased and determine the kg they represent given that 1 kg is equal to 2.20 lb:
1250+1500=2750
2.20 lb → 1 kg
2750 lb → x
x=(2750*1)/2.20= 1250 kg
Now, you can find the total amount sold by multiplying the price per kilogram for the amount of kg:
$6.75*1250=$8,437.5
Finally, you have to subtract the total cost from the total amount sold:
$8,437.5-$3,862.5=$4,575
According to this, the answer is that after paying her suppliers, she made $4,575.

Answer:
C = 13, A = 18
Step-by-step explanation:
A = 5 + C
A + 4 = 2(c-2)
5+c+4 = 2c - 4
9 + c = 2c - 4
c = 2c - 13
-1c = -13
c = 13
A = 5 + 13
A = 18
i don't understand. May you help?
Answer:
Step-by-step explanation:
Function rule:
y = 10(0.95)ˣ
If a function is given as,
y = a(b)ˣ
a represents 'Initial value'
b represents the growth factor
If 0 < b < 1, function is a decay function.
If b > 1, function is a growth function.
For 2 = 10(0.95)ˣ,
Here, b = 0.95 which is in the interval of 0 < 0.95 < 1
So it's a decay function.
[tex]\frac{2}{10}=(0.95)^x[/tex]
log(0.2) = log[(0.95)ˣ]
log(0.2) = x[log(0.95)]
-0.6989 = -x(0.0223)
x = 31.44
x ≈ 31
Meaning → For 'x' = 31, value of the function is 2.
For 8 = 10(0.95)ˣ,
0.8 = (0.95)ˣ
log(0.8) = log(0.95ˣ)
log(0.8) = xlog(0.95)
x = 4.35 ≈ 4.4
Means, at x = 4.4, value of the function was 8.

Answer:
-1 < x ≤ 3
Step-by-step explanation:
First, we need to simplify this inequality.
9 > -5x + 4 ≥ -11 (Given)
5 > -5x ≥ -15 (Subtract 4 on both sides)
-1 < x ≤ 3 (Divide -5 on both sides)
Note that the signs flip due to dividing by a negative number.
Answer:
[tex]-1<x\leq3[/tex]
Step-by-step explanation:
Let's take two equations from this and them put them back together! So:
9>-5x+4
and
[tex]-5x+4\geq -11[/tex]
For the first one:
9>-5x+4
Subtract 4 from both sides
5>-5x
Then divide by -5 (Remember to change the direction of the sign!):
-1<x
Now onto the second one:
[tex]-5x+4\geq -11[/tex]
Subtract 4 from both sides:a
[tex]-5x\geq -15[/tex]
Then divide by -5 (Remember to change the direction of the sign!):
[tex]x\leq 3[/tex]
Now add the equations back together:
[tex]-1<x\leq3[/tex]
FAST ILL MARK U BRAINLIEST Write an equation of the line that passes through (2, −1) and is parallel to the line 2y + 3x = 8 . Write your answer in slope intercept form.
Answer:
y=[tex]-\frac{3}{2}[/tex]+2
Step-by-step explanation:
for an equation to be parallel with another both should have the same rate of change(m).
the line given to us is in general form, and we can change it to slope-intercept form to get the slope. (y=mx+b)
Isolate for y:
2y+3x=8
2y=-3x+8
y=-3/2x+8/2
y=-3/2x+4
thus the slope of the line we are trying to find must also equal -3/2
use point slope form to find the equation (substitute (2, -1) into equation)
y-y1=m(x-x1)
y-(-1)=(-3/2)(x-2)
y+1=[tex]-\frac{3}{2}[/tex]x+3
y=[tex]-\frac{3}{2}[/tex]+2
Martin is laying out a design for the tiles on a section of his bathroom floor. He will use 1 black tile for every 4 white tiles to have total of 20 tiles in the design. How many of each type of tile will Martin use?
Answer:
[tex]Black = 4[/tex]
[tex]White = 16[/tex]
Step-by-step explanation:
Given
[tex]Black : White = 1 : 4[/tex]
[tex]Total = 20[/tex]
Required
Determine the number of each type used
Convert each ratio to fraction.
For Black, we have:
[tex]Black = \frac{1}{1 + 4} = \frac{1}{5}[/tex]
For White, we have:
[tex]White = \frac{4}{1 + 4} = \frac{4}{5}[/tex]
The number of tiles for each is then calculated as:
[tex]Black = \frac{1}{5} * Total[/tex]
[tex]Black = \frac{1}{5} * 20[/tex]
[tex]Black = \frac{20}{5}[/tex]
[tex]Black = 4[/tex]
[tex]White = \frac{4}{5} * Total[/tex]
[tex]White = \frac{4}{5} * 20[/tex]
[tex]White = \frac{4 * 20}{5}[/tex]
[tex]White = \frac{80}{5}[/tex]
[tex]White = 16[/tex]

There are a total of 56 students in the art club and the math club. The art club has 12 more students
than the math club. Write and solve a system of equations to find the number of students in each club.
Let x = students in the art club and y = students in the math club
Solution:
students in the art club and
students in the math club
Blank 1:
Blank 2:
Answer:
The math club has 22 students, and the art club has 34 students.
Step-by-step explanation:
Given that there are a total of 56 students between the art club and the math club, and that the art club has 12 more students than the math club, to determine how many students there are in each club, the following calculation must be performed:
X + X + 12 = 56
2X + 12 = 56
2X = 56 - 12
X = 44/2
X = 22
Thus, the math club has 22 students, and the art club has 34 students.
