Find the m∠SAQ.
44°
46°
57°
77°
Answer:
X=57
Step-by-step explanation:
77+46+X=180
123+X=180
X=180-123
X=57
Answer:
57°
Step-by-step explanation:
Hope it helps you in your learning process
46° + m∠SAQ + 77° = 180° (straight line angles)
m∠SAQ + 123° = 180°
m∠SAQ = 180° - 123°
m∠SAQ = 57°
The equation of the graphed line is 2x – 3y = 12.
A coordinate plane with a line passing through (0, negative 4) and (6, 0).
What is the x-intercept of the graph?
–4
–Negative StartFraction 3 Over 2 EndFraction
StartFraction 2 Over 3 EndFraction
6
Step-by-step explanation:
Well, if you're trying to find the x-intercept, you should look where the line crosses the x-axis. If the line crosses at 6, then the x-intercept is 6. So what I'm saying is the answer is 6.
Btw, if you're trying to find the y-intercept, just look where the line crosses the y-axis, (vertical axis) and then that's your answer.
Example: If there is a line crossing through a 5 on the y-axis, that is your y-intercept.
Example: If there is a line crossing through a 5 on the x-axis, that is your x-intercept.
I hope this answers your question.

Help pls so people say it’s none of these but idk I am confused.
Answer:
Volume = [tex]\pi r^2 h[/tex]
2512 = 3.14 × r^2 × 8
[tex]r^2 = \displaystyle\frac{314}{3.14}[/tex]
[tex]r^2 = 100[/tex]
[tex]r = 10 \ cm[/tex]
[tex]Diameter = 2r = 20 \ cm [/tex]
Dont get confused try to understand : )
Answer:
20 cm
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We are given the volume and the height
2512 = pi r^2 *8
Divide each side by 8
2512/8 = pi r^2 *8/8
314 = pi r^2
Divide each side by pi
314/3.14 = 3.14 r^2 /3.14
100 = r^2
Take the square root of each side
sqrt(100) = sqrt(r^2)
10 = r
We want to find the diameter
d =2r
d =2(10)
d =20
The diameter is 20 cm

There are 13 brunettes and 7 blondes in a Spanish class. The teacher selects two students to run an errand. How many possible outcomes are there if she selects a brunette followed by a blonde?
Answer:
91 possible outcomes
Step-by-step explanation:
As the teacher selects a brunette followed by a blonde, we just need to find the number of possibilities of choosing a brunnette and the number of possibilities of choosing a blonde:
number of possibilities of choosing a brunette: 13
number of possibilities of choosing a blonde: 7
Then, the number of possible outcomes is the product of these number of possibilities:
13 * 7 = 91 possible outcomes

The diagram shows the number of children who have ever used motorized scooters, manual scooters, and/or bicycles. Circles labeled Motor and Manual overlap. A circle labeled bicycle is to the side of the other 2 circles. Circle Motor contains 8 and circle Manual contains 32. The overlap of the circles contains 24. Circle Bicycle contains 44. Number 3 is on the outside of the circles. Which combination represents the empty set? motor ⋃ manual motor ⋃ bicycle motor ∩ manual motor ∩ bicycle
Answer:
motor ∩ bicycle
Step-by-step explanation:
This is because ∩ means intersection, saying that it is an overlap between the motor and the bicycle, but on the chart there is no overlap between those two.
Answer:
C: motor ∩ bicycle

Answer:
y = 3x
Step-by-step explanation:
The difference between consecutive values of y are constant, that is
9 - 6 = 6 - 3 = 3 - 0 = 0 - (- 3) = - 3 - (- 6) = 3
This constant is the required multiplier, that is
y = 3x
Kali has a 6 meter ladder that she wants to use to get her cat out of a tree. She puts the base of the ladder 2
meters away from the base of the tree. How high into the tree will the ladder reach? Round your answer to the nearest tenth of a meter.
Answer:
5.7m
Step-by-step explanation:
the easiest way to solve for a side is to draw the question in a diagram (i have done this below). As it is a right-angled triangle and we know 2 of the side, we can use the Pythagoras theorem:
[tex]a^{2} +b^{2} =c^{2}[/tex]
sides a and b are the two shorter sides.
side c is the hypotenuse (longest side)
as shown in the picture below, because we know both sides c and b, we need to change the equation around:
[tex]c^{2} -b^{2} =a^{2}[/tex]
replace these sides with their numbers:
[tex]6^{2} -2^{2} = 32[/tex] (remember that 32 equals side a squared therefore we need to square root 32 to find the length of side a:
[tex]\sqrt{32} =5.65685...[/tex]
the question says to round to the nearest tenth meter:
Missing side = 5.7m

Pure acid is to be added to a 5% acid solution to obtain 95L of 98% solution. What amounts of each should be used?
How many liters of 100% pure acid should be used to make the solution?
Answer:
Step-by-step explanation:
Equation:
acid + acid = acid
0.05x + 1.0(95-x) = 0.30*95
----
Multiply thr by 100 to get:
5x + 100*95 - 100x = 30*95
---
-95x = -70*95
---
x = 70L (amt of 5% solution needed)
---
95-x = 25L (amt of 100% solution needed)
==================================================
How many Liters of 100% acid should be used to obtain the solution?

Find the difference: 4/5 - 1/3
Answer:
7/15
Step-by-step explanation:
When we convert the fractions so that they have a common denominator (this makes it easier to subtract), we get 12/15 - 5/15 = 7/15. Hope this helps!
Answer:
7/15
Step-by-step explanation:
First, you find a common denominator. The common denominator would be 15.
4/5= 12/15
1/3= 5/15
12/15- 5/15
Answer: 7/15

so the dividend and divisor were both multiplied by 100.simplify 3x + 5 + 7 x - 3 - x + 2
Before we do this problem, let's go over a little algebra terminology.
The number in front of your variable is called your coefficient and notice that the x at the end of the problem does not have a coefficient.
When that happens, when there is no number in front of your variable, you can put a 1 there to fill that position. So -x can be thought of as -1x.
Next let's change all our minus signs to plus negatives.
So the problem reads 3x + 5 + 7x + -3 + -1x + 2.
Now let's simplify this by combining like terms.
We can combine our "x" terms first.
3x + 7x + -1x simplifies to +9x.
Now, 5 + -3 + 2 simplifies to 4.
So our answer is 9x + 4.

Your dad is designing a new garden for your backyard. He has 26 feet of fencing to go around the garden. He wants the length of the garden to be 3 1/2 feet longer than the width. How wide should he make the garden?
Answer:
4.75 feet
Step-by-step explanation:
Perimeter for any rectangular shape is given by 2(length + width).
Fencing the garden means one wiring the garden along the perimeter.
Thus, it can be concluded that garden has perimeter of 26 feet as given in question.
__________________________________________
Let the width be x feet
given that, He wants the length of the garden to be 3 1/2 feet longer than the width
thus, length of garden = x + 3 1/2 feet = x + 3.5 feet
if length is x+3.5 feet and width is x feet.
Then perimeter = 2( x+3.5 + x) = 2(2x+3.5) = (4x + 7) feet.
This perimeter will be equal to 26 feet fence
thus,
(4x + 7) = 26
=> 4x = 26 - 7 = 19
=> x = 19/4 = 4.75 feet
x is width of garden.
Thus, he should make the garden 4.75 feet wide.

Answer:
V = 687.28 cm ^3
Step by step explanation:
687.28 m ^3 is found in 3 steps.
Volume of a sphere = V=4/3πr3 = 268.8 m^3
Volume of a semi sphere = V = (2/3)πr. but i divide the top one by 2
= 268.8/2 = 134.4 m^3
Volume of a Cylinder prism = V=πr2h = 502.61 m^3
Volume of a cone V=(πr2 )h/3 = 50.27
We add 134.4 + 502.61 +50.27 = 687.28 m ^3
How to find Area;
We remember and compare to Area and other areas the values.
Area = 415m^2
circle is semi sphere A = π r2 h= 200.1 = /2 or *0.5 A=100.53 m^2
cylinder lateral A = 2πrh L = 251.327412 m^2 = 251 m^2
Cone lateral A=πrh2+r2 = 62.83 = 63 m^2
= 100.53 + 251.327412 + 62.83 =414.687412
or 101+251+63 = 415 m^2
Notes;
The best way is to find someway of not overwhelming yourself with the combined volume question and know what actually makes a cylinder being the central prism.
So write down all these values below onto a flashcard and title it Area of a composite Semi-sphere/cylinder/cone r = 4 / h= 10 r =4 / r= 4 h=3
and write these down.
Cylinder
lateral surface area L = 80 π m2
top surface area T = 16 π m2
base surface area B = 16 π m2
total surface area A = 112 π m2
Cone = 62.83
Semi sphere = 100.53
Area = 415 m2
