Solve for the value of x
Answer:
x = 47°
Step-by-step explanation:
The secant- secant angle (x) is half the difference of the intercepted arcs, that is
x = [tex]\frac{1}{2}[/tex] (133 - 39)° = 0.5 × 94° = 47°
A student answered 40 problems on a test correctly and received a grade of 80%. How many problems were on the test, if all the problems
were worth the same number of points?
Answer:
Step-by-step explanation:
80x/100 = 40
80x = 4000
x= 50 problems
Answer:
50 problems
Step-by-step explanation:
40÷2 =20 = 40% 20÷2 =10 = 20%
if 10 =20% then 10 × 5 = 50 or 80%

2x – 5 > 3 or 11 – 3x > -2
Answer:
x > 4 and x <3
Step-by-step explanation:
Given the system of inequalities
2x – 5 > 3 or 11 – 3x > -2
for 2x – 5 > 3
2x > 3+5
2x>8
x>8/2
x> 4
For 11-3x > -2
-3x > 2-11
-3x > -9
x < -9/-3
x<3
hence the result will be x > 4 and x <3

what does the E stand for in 3.1536e+17
Answer:
well e stands for like what you multiply
Step-by-step explanation:
like well here is an example y=16e and you have to find what e stands for so E=
3x - 2y= 5, 4x + 3y= 1
Answer:
x=17 and y=23 DONT SUE ME IF I GET THIS WRONG PLZZ ;-;
Step-by-step explanation:
Answer:
(1, - 1 )
Step-by-step explanation:
Given the 2 equations
3x - 2y = 5 → (1)
4x + 3y = 1 → (2)
Multiplying (1) by 3 and (2) by 2 and adding the result will eliminate y- term
9x - 6y = 15 → (3)
8x + 6y = 2 → (4)
Add (3) and (4) term by term to eliminate y
17x + 0 = 17
17x = 17 ( divide both sides by 17 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for y
Substituting into (2)
4(1) + 3y = 1
4 + 3y = 1 ( subtract 4 from both sides )
3y = - 3 ( divide both sides by 3 )
y = - 1
solution is (1, - 1 )
A bag contains 4 Snickers bars and 1 Twix bar, and the outcome is drawing a Twix bar. Does the phrase that describes the probability of drawing a Twix bar
A.
No, because there are still only two possible outcomes.
B.
No, because it is still less likely to have an outcome of drawing a Twix.
C.
Yes, because there are still only two possible outcomes.
D.
Yes, because it is still less likely to have an outcome of drawing a Twix.
Answer:
Yes because there are still only two possible outcomes

possible number of learners in the
in a village, the bell rings every 30 minutes at the Junior School and every 40
minutes at the High School Both schools start lessons at 8:00 am
At what times between 8.00 am and 2.30p.m do the bells both rring
Find multiples of 30 and 40:
30: 30, 60, 90, 120, 150
40: 40, 80, 120, 160
The least common multiple is 120, so every 120 minutes they willl both ring.
1 hour = 60 minutes:
120/60 = 2 hours.
The bells ring together every 2 hours.
8 + 2 = 10 am
10 + = 12pm
12 + 2 = 2 pm
The bells will ring together at am, 12 pm and 2 pm.
Answer:
Solution :-At first common multiple of 30 an 40
[tex] \sf \to \: 30 = 30,60,90,120[/tex]
[tex] \sf \to \: 40 = 40,80,120[/tex]
Common Multiple = 120
Time taken = 120/60 = 2 hrs
Now,
8.00 + 2 = 10.00 am
10.00 + 2 = 12.00 noon
12.00 + 2 = 2.00 pm

Which could be the value of x in the
triangle below?
Answer:
6
Step-by-step explanation:
I'm going to assume that this is a right triangle
which means that
3x²+6²=19²
9x²+36=361
9x²=325
3x=18.0277
x=6
If $18\sqrt 8-8\sqrt{18}=\sqrt n, what is n?
Answer:
288 trust me it is 100% right I tried it as an answer an got it right.
Step-by-step explanation:
Answer:
288
Step-by-step explanation:
From the first two parts of the problem, we have
18√8 - 8√18 = 36√2 - 24√2
= (36 - 24)√2
= 12√2.
Thus, we wish to solve for n in the equation 12√2 = √n. In other words, we want to know what number 12√2 is the square root of. Any nonnegative number is the square root of its own square, so
n = (12√2)²
= 12²(√2)²
= 144 ∙ 2
= 288.
A water rocket is launched froni a platform. The height,
h in metres, of the water rocket at time & seconds after
it is launched is h= -212 + 74 + 4. When does the water
rocket hit the ground?
Answer:
4.41seconds later
Step-by-step explanation:
Let the equation of the height reached by the water front be h = -2t^2+7t+4
The water hits the ground at h =0
Substitute
0 = -2t^2+7t+4
-2t^2+7t+4 = 0
2t^2 - 7t - 8 = 0
t = 7±√(-7)²-4(2)(-8)/2(2)
t = 7±√49+64/4
t = 7±√113/4
t = 7±10.63/4
t = 7+10.63/4
t = 17.3/4
t = 4.41s
Hence the water hit the ground 4.41seconda later

Lisa had four candy bars . She ate 2 3/8 of the candy bars. How many candy bars does she have left.
Answer:
1 5/8
Step-by-step explanation:
You need to do the subtraction 4 - 2 3/8.
You can use mixed numerals, but you need to borrow and you need a common denominator.
4 - 2 3/8
Since 4 has no fraction part, we borrow 1 from 4 leaving 3. The 1 we borrow becomes a fraction written as 8/8, so we have the same denominator as the fraction 3/8.
Now we have
4 - 2 3/8 =
= 3 8/8 - 2 3/8
Subtract 2 from 3 to get 1.
Subtract 3/8 from 8/8 to get 5/8.
= 1 5/8
You can also set it up vertically as shown below and then subtract the whole numbers and subtract the fractions.
3 8/8

[tex]\frac{12}{49}[/tex]
Step-by-step explanation:
Given
[tex]\frac{4}{7}[/tex] ÷ 2 [tex]\frac{1}{3}[/tex] ← change mixed number to improper fraction
= [tex]\frac{4}{7}[/tex] ÷ [tex]\frac{7}{3}[/tex]
To perform the division
Leave the first fraction. change division to multiplication and turn the second fraction upside down.
= [tex]\frac{4}{7}[/tex] × [tex]\frac{3}{7}[/tex] ← multiply numerators/ denominators together
= [tex]\frac{4(3)}{7(7)}[/tex]
= [tex]\frac{12}{49}[/tex]

6% of 95 is 5.7
so its $5.70
Which piece of information below will not help you prove that triangles ABC and DEF are congruent using ASA?
Answer:
A) [tex]AC=DF[/tex]
Step-by-step explanation:
Given
See attachment for triangles ABC and DEF
Options
A) [tex]AC=DF[/tex]
B) [tex]AB=DE[/tex]
C) [tex]\angle B=\angle E[/tex]
D) [tex]\angle A=\angle D[/tex]
Required
Which does not prove the congruence of ABC and DEF using ASA?
From the attachment, we have the following:
[tex]\angle A = \angle D[/tex] --- Angle
[tex]AB = DE[/tex] --- Side
[tex]\angle B = \angle E[/tex] ---- Angle
The ASA theorem means that 1 side of both triangles are equal.
By comparing the listed parameter to the options, we can see that options B, C and D prove that both triangles are congruent by ASA.
However, option A [tex]AC=DF[/tex] cannot be used because that will mean that two sides of both triangles are equal. This does not support the ASA theorem
