Answer:
d=75° e=28° f=77°
Step-by-step explanation:
The angle of a straight line is 180°
If you subtract the 2 angles you know(which are equal to d and e), you're left with the missing angle measurement of 77°
Logan has two aquariums. One aquarium contains 1.3 cubic feet of water and the other contains 1.9 cubic feet of water. The water in the larger aquarium weighs 37.44 pounds more than the water in the smaller aquarium. Write an equation with a variable on both sides to represent the situation. Then find the weight of 1 cubic foot of water.
Answer:
62.4
Step-by-step explanation:
1. 1.3x+37.44=1.9x
2. 1.3x+37.44-1.3x=1.9x-1.3x
0.6x=37.44
3. x=37.44/0.6=62.4
The weight of 1 cubic foot of water is 62.4 lb.
Representing Equation with variable on both sides
Let 'x' pounds be the weight of 1 cubic foot of water.
We know one aquarium contains 1.3 cubic feet of water. So, the weight of 1.3 cubic feet of water = 1.3x
The other aquarium contains 1.9 cubic feet of water. So, the weight of 1.9 cubic feet of water = 1.9x
It is given in the question that the water in the larger aquarium weighs 37.44 pounds more than the water in the smaller aquarium.
The equation would be
1.9x = 1.3x + 37.44
The above equation quality the condition of variable on both sides.
To find out the weight of 1 cubic foot of water, we will solve the above equation to find the value of x.
1.9x = 1.3x + 37.44
1.9x - 1.3x = 37.44
0.6x = 37.44
x = 37.44/0.6
x = 62.4
So, the weight of 1 cubic foot of water is 62.4 lb.

Suppose that 19 inches of wire costs 76 cents. At the same rate, how many inches of wire can be bought for 48 cents?
Answer: 12 inches
Step-by-step explanation:
Because 19 inches costs 76 cents. If you divide 19/19 you get 1 inch. Also divide 76/19 and you get 4 cents. Now it’s asking how many inches could be bought for 48 cents. So 48/4 equals to 12 and that’s your answer. You see 19x4=76. And 12x4= 48. I hope that helped you.

Isabella bought 71.4 ounces of chocolate. 1.21 ounces of it was milk chocolate and the rest was dark chocolate. How much dark chocolate did Isabella buy?
Answer:
Isabella bought 70.19 ounces of dark chocolate.
Step-by-step explanation:
You want to subtract the total which is 71.4 minus the 1.21 ounces of the white chocolate, you then will get 70.19 ounces of dark chocolate. To be sure, you can add 70.19+1.21 and will get you the total amount of ounces of chocolate. Hope this helps :D
What is an equation of the line that passes through the point
(-6, -2) and is parallel to the line 3x – 2y = 2?
Answer: y=3/2x+7
Step-by-step explanation:
To find the equation of the line that passes through the given point, let's first convert the given equation to slope-intercept form.
3x-2y=2 [subtract both sides by 3x]
-2y=-3x+2 [divide both sides by -2]
y=3/2x-1
Now that we have the equation in slope-intercept form, we know that the slope must stay the same because parallel lines NEVER touch. All we have to do is plug in the given point to find the y-intercept.
-2=3/2(-6)+b [multiply]
-2=-9+b [add both sides by 9]
b=7
Now, we know that the parallel equation is y=3/2x+7.

i got 100% on this quiz
The solutions to the equation x³ = 36, x² = 42, x³ = 55 are:
x = ∛36
x = √42
x = ∛55
Option B, D, and F are the correct answers
Given,
Which of these is a solution to the equation x³ = 36, x² = 42, x³ = 55
Select three that apply.
A. x = √36
B. x = √42
C. = √55
D. = ∛36
E. = ∛42
F. = ∛55
How do we write square root and cube root?- Square root of a is written as √a.
- Cube root of a is written as ∛a.
We have,
- x³ = 36
Cube root on both sides
∛x³ = ∛36
x = ∛36
- x² = 42
Squaring on both sides
√x² = √42
x = √42
- x³ = 55
Cube root on both sides
∛x³ = ∛55
x = ∛55
We see that,
x = ∛36
x = √42
x = ∛55
Thus the solutions to the equation x³ = 36, x² = 42, x³ = 55 are:
x = ∛36
x = √42
x = ∛55

Write each of the following numbers as a power with a rational exponent:
2[tex]2\sqrt32[/tex]
Answer:
2^(7/2)
Step-by-step explanation:
Here, we want to write 2√32 as a power with a rational exponent.
That would be 2 * √32
= 2 * 32^1/2
= 2 * 2^5(1/2)
= 2 * 2^5/2
According to law of indices, this becomes the following;
2^(1 + 5/2)
= 2^(7/2)
Places A and B are 100km apart from each other on a highway. A car starts from A and another from B at the same time. If they move in the same direction, they meet in 10 hours and if they move in opposite directions, they meet in 1 hour and 40 minutes. Find the speeds of the cars.
Answer:
Speed of the first car = x = 35km/hr
Speed of the second car = 25km /hr
Step-by-step explanation:
The calculation of speeds of the cars is given below:-
Assume that the speed of the 1st car which is opening from A = x km/hr
and assume the Speed of the 2nd car which is starting from B
= y km/hr
As we know that
Time = Distance ÷ Speed
So, the distance lies between two places i.e. A and B are
80km d = 80 km
1. now when the car moves in the similar direction
So, the corresponding speed of them = (x + y)km/hr
Time = 8hr
d = 80km
[tex]8 = \frac{80}{(x + y)}\\\\x + y = \frac{80}{8}\\\\x + y = 10 ..... (i)[/tex]
2. when two cars moving in the inverse direction,
So, the corressponding speed = (x - y) km / hr
Time = 1 hr 20 minutes
That means
= (1 + 20 ÷ 60) hr
= (80 ÷ 60)
= 4/3 hr
d = 80km
Now
4 ÷ 3 = 80 ÷ (x -y)
x -y = (80 × 3) ÷ 4
x - y = 60 ..... (ii)
Now, we will sum equation 1 and equation 2 we will get
2x = 70
x = 35
now, Put x = 35 in (i) we will get
y = 25
Speed of the first car = x = 35km/hr
Speed of the second car = 25km /hr

A right rectangular prism is packed with cubes of side length fraction 1 over 5 inch. If the prism is packed with 15 cubes along the length, 6 cubes along the width, and 5 cubes along the height, what is the volume of the prism? (1 point) Group of answer choices A. Fraction 2 and 3 over 10 cubic inches B. Fraction 3 and 3 over 5 cubic inches C. Fraction 7 and 1 over 5 cubic inches D. Fraction 7 and 1 over 10 cubic inches
Given:
A right rectangular prism is packed with cubes of side length [tex]\dfrac{1}{5}[/tex] inch.
Prism is packed with 15 cubes along the length, 6 cubes along the width, and 5 cubes along the height.
To find:
The volume of the prism
Solution:
Side length of each cube [tex]=\dfrac{1}{5}[/tex] inch.
15 cubes along the length, so length of prism is
[tex]l=15\times \dfrac{1}{5}=3\text{ inches}[/tex]
6 cubes along the width, so width of prism is
[tex]b=6\times \dfrac{1}{5}=\dfrac{6}{5}\text{ inches}[/tex]
5 cubes along the height, so height of prism is
[tex]h=5\times \dfrac{1}{5}=1\text{ inch}[/tex]
Now,
Volume of rectangular prism is
[tex]V=l\times b\times h[/tex]
[tex]V=3\times \dfrac{6}{5}\times 1[/tex]
[tex]V=\dfrac{18}{5}[/tex]
[tex]V=\dfrac{3\times 5+3}{5}[/tex]
[tex]V=3\dfrac{3}{5}\text{ cubic inches}[/tex]
Therefore, the correct option is B.
