Answer:
[tex]\Huge \boxed{{x=56\°}}[/tex]
Step-by-step explanation:
Angles on a straight line add up to 180 degrees.
Create an equation.
64 + x + 60 = 180
Solve for x.
Add the numbers.
x + 124 = 180
Subtract 124 from both sides.
x + 124 - 124 = 180 - 124
x = 56
Answer:
56°
Step-by-step explanation:
64 + 60 = 124180 - 124 = 56Why?
We did 64 + 60 because they are the two degrees that is given to us, and those two added with x will give us 180.When we add 64 and 60 together, we get 124. We then subtract that total from the total of the three angles to give us the remaining angle., which is 56.Therefore, x is 56°
Which expression is equivalent to √-60? A) -2√15 B) -4√15 C) 4i√15 D) 2i√15
Answer:
d) 2i√15

Write the slope intercept form of the equation for the line.
Answer:
y = 2x -1
Step-by-step explanation:
y = mx + b
On the y-axis which is the vertical line, it touches the line is on -1.
Therefore, -1 is the y-intercept which is b.
y = mx - 1
Now the slope since it goes up 2 and right one to reach a point again the slope is 2/1 which basically just 2.
Now y = 2x - 1

The four angles in a quadrilateral are in the ratio 2:5:6:7. Find the smallest angle in the quadrilateral?
Answer:
36º
Step-by-step explanation:
Since all the angles are in a ratio, and all angles add up to 360º, we can set up a simple equation to find the smallest angle.
2x + 5x + 6x + 7x = 360
20x = 360
x = 18
18 is NOT the answer since the smallest angle has a ratio number of 2. So we multiply 18 with 2 to get 36º.

Answer:
36
Step-by-step explanation:
The four angles of a quadrilateral add to 360
2:5:6:7
Multiply by x
2x:5x:6x:7x
Add them together to get 360
2x+5x+6x+7x = 360
20x = 360
Divide each side by 20
20x/20 = 360/20
x =18
The smallest angle is 2x
2*18 = 36

Answer:
There is a probability of 0 that the student plays both string and brass.
Step-by-step explanation:
Looking at the universal set, there are 40 students at this high school, 15 of which play string, 20 play brass, and 5 play neither (probably drummers). Note how there is no intersection of A and B, which is the probability we are looking for.
Since there is no intersection in the universal set between subset A and subset B, you can say that there is a probability of 0 since there is no overlap between the two subsets.

Step-by-step explanation:
First, write out the equation as you have it:
[tex]58-10x\leq20+9x[/tex]
Then, add [tex]10x[/tex] to both sides:
[tex]58-10x+10x\leq20+9x+10x\\58\leq20+19x[/tex]
Next, subtract [tex]20[/tex] from both sides:
[tex]58-20\leq20-20+19x\\38\leq19x[/tex]
Finally, divide both sides by [tex]19[/tex]:
[tex]\frac{38}{19}\leq\frac{19x}{19}\\2\leq x[/tex]
or
[tex]x\geq 2[/tex]
Therefore: the answer to this inequality/equation is: x≥2
Earl needs to fill juice cups for his little brother's birthday party. There are 25 juice cups and each juice cup holds 12 fluid ounces. The juice comes in 1-gallon bottles. How many 1-gallon bottles of juice will Earl need to purchase? (2 points) (1 quart = 32 fluid ounces, 1 gallon = 4 quarts) 1 bottle 2 bottles 3 bottles 4 bottles
Answer:
3 bottles
Step-by-step explanation:
Hello!
First, we find out how many fluid ounces 25 cups of juice hold.
One cup holds 12 fluid ounces so to find 25 we do
25 * 12 = 300 fluid ounces
Next, we find out how many fluid ounces one gallon holds.
One gallon is 4 quarts.
1 quart is 32 fluid ounces so to find how many 4 holds we do
32 * 4 = 128
So one gallon holds 128 fluid ounces
To find how many we need we divide the total needed by how much one bottle holds
300/128 = 2.34
You can't buy exactly 2.34 bottles of juice so we round up to the nearest whole number we will just have extra leftover
The answer is 3 bottles

A scientist is conducting a study on the effect of eating chocolate and overall mood. They believe that gender is a significant factor. The participants are divided by gender. Then, within each group, participants are randomly assigned to consume either chocolate or a placebo and then rate their mood for the day. This experiment will run for two weeks. Which type of experimental design does this situation describe?
A. Randomized Block Design.
B. Matched-Pair Design.
C. Case-Control Design.
D. Completely Randomized Design.
Answer:
The correct option is;
A. Randomized block design
Step-by-step explanation:
A randomized block design is one where the sample or subjects of the experiment are split into groups called blocks of experimental units where the variation in each block is lower than the variation among or between blocks, such that variation is controlled. In a random order, the treatments are performed on each experimental of the blocks.
In the question, the experimental units are grouped by gender and the treatment (consumption of chocolate or placebo) is randomly administered to the experimental units.

Answer:
The answer is option DStep-by-step explanation:
To find the length of AB we use the formula
[tex] \sqrt{ ({x _{1} - x_{2}})^{2} + ({y_{1} - y_{2} })^{2} } [/tex]
Where
(x1 , y1) and (x2 , y2) are the points
From the question
A is (4 , 5) B is (2 , 2)
So the length of AB is
[tex] |AB| = \sqrt{ ({4 - 2})^{2} + ({5 - 2})^{2} } [/tex]
[tex] |AB| = \sqrt{ {2}^{2} + {3}^{2} } [/tex]
[tex] |AB| = \sqrt{4 + 9} [/tex]
We have the final answer as
[tex] |AB| = \sqrt{13} [/tex]

Answer:
sqrt(13) = c
Step-by-step explanation:
The length of BC = 4-2 =2
The length of AC = 5-2 =3
We can use the Pythagorean theorem
a^2 + b^2 = c^2
2^2 + 3^2 = c^2
4+9 = c^2
13 =c^2
Take the square root of each side
sqrt(13) = c

Just took quiz.
Based on the calculations, the volume of this pyramid is equal to: D. 324 cm³.
Given the following data:
Base area = 54√3 cm².Edge length = 6 centimeters.Angle BAC = 60°.How to calculate the volume of a pyramid?Mathematically, the volume of a pyramid can be calculated by using this formula:
Volume = 1/3 × base area × height
Next, we would find the height of this pyramid from the right-angled triangle ABC by applying Tan trigonometry formula:
Tanθ = Opp/Adj = BC/AC
Tan60 = height/6
√3 = height/6
Height = 6√3 cm.
Now, we can calculate the volume of this pyramid:
Volume = 1/3 × base area × height
Volume = 1/3 × 54√3 × 6√3
Volume = 1/3 × 972
Volume = 324 cm³.

fives times a number and the difference of 6
Answer: The equation that has resulted from this is 5x - 6.
Step-by-step explanation:
So far, we know that the givens are:
fives times a number and the difference of 6
Then, we can conclude that the term "a number" means an unknown term, so all we have to do is put a variable in its place. It can be k, s, h, z, x, etc. Next, just find the difference of 6. So, from what we know, this is what our new equation looks like:
5 times ( a number) - the difference of 6
In math form:
5 (x) - 6
Simplify:
5x - 6

On a map, 1/4 inch between locations represents an actual distance of 2 miles between the locations. What is the actual distance, in miles, between the two cities that are 3 3/4 inches apart on the map?
Answer:
30 miles
Step-by-step explanation:
1/4 = 2
3 3/4 = x
15/4 = x
So, Cross multiply
=> 1/4 * x = 15/4 * 2
=> 1/4x = 15/4 * 4/2
=> 1/4x = 60/8
=> 1/4x = 7.5
=> 1/4x * 4 = 7.5 * 4
=> x = 30
So, 15/4 inches on the map equals 30 miles.
