Answer:
x = 89°
Explanation:
The angles inside a triangle will always add up to 180°
49 + 42 = 91
180 - 91 = 89°
If you have $4.00, how many pounds of apples can you buy?
A. 7 pounds
B. 7/4 of a pound
C. 4/7 of a pound
D. 2 2/7 pounds
Answer:
[tex]2 \frac{2}{7}[/tex] pounds, D
Step-by-step explanation:
1 pound of apples = 1.75 dollars.
Set the number of pounds of apples as x.
Then, we can write this equation.
1.75x = 4
[tex]\frac{7}{4}[/tex]x = 4
Divide both sides by [tex]\frac{7}{4}[/tex]
x = [tex]\frac{4}{1}[/tex] * [tex]\frac{4}{7}[/tex]
x = [tex]\frac{16}{7}[/tex]
x = [tex]2 \frac{2}{7}[/tex]
Thus, the answer is D, x = [tex]2 \frac{2}{7}[/tex] pounds

Answer:
D.
Step-by-step explanation:
its a right triangle, so we can use the pythagorean theorem to find h
(pythagorean theorem is a^2+b^2=c^2, c is the hypotenuse)
h^2+4^2=13^2
h^2+16=169
h^2=153

the spinner shown below has 12 congruent sections. the spinner spun 150 times. what is a reasonable prediction for the number of items the spinner will land on an even number. (pls help asap!!)
Answer:45
Step-by-step explanation:
There are 3 even numbers out of A total of 8 numbers.
Each spin would have a 3/8 chance of landing in an even number.
Multiply the chance of landing on even by number of spins:
120 x 3/8 = 360/8 = 45
The answer would be 45 times.

f(x)= square root of x-5. find f-1 (x) and it’s domain
Answer:
Option B.
Step-by-step explanation:
Inverse function:
Suppose we have a function y = f(x). To find the inverse function, we exchange x and y on the original function, and then isolate y.
The domain of the inverse function(x values) is the range of the original function(y values).
Original function:
[tex]f(x) = \sqrt{x} - 5[/tex]
Domain is [tex][0,\infty)[/tex], and when [tex]x = 0, f(x) = -5[/tex]. So the range is [tex][-5,\infty][/tex], that is, [tex]y \geq -5[/tex]
Inverse function:
[tex]y = \sqrt{x} - 5[/tex]
Exchanging x and y
[tex]x = \sqrt{y} - 5[/tex]
[tex]\sqrt{y} = x + 5[/tex]
[tex](\sqrt{y})^2 = (x+5)^2[/tex]
[tex]y = (x+5)^2[/tex]
The inverse function is [tex]f^{-1}(x) = (x+5)^2[/tex]
Domain:
Range of the original function is [tex]y \geq -5[/tex], so the domain of the inverse function is [tex]x \geq -5[/tex]. The correct answer is given by option B.
Answer:
B. f ^ -1 (x) = (x + 5) ^ 2;

The equation of the line that goes through the point ( 3 , 4 ) and is parallel to the line 3 x + 4 y = 2 can be written in the form y = m x + b
Answer:
y = -3x/4 + 25/4
Step-by-step explanation:
3x + 4y = 2
-3x -3x
4y= -3x + 2
4y/4 = -3x/4 + 2/4
y = -3x/4 + 1/2 mx= -3x/4
y = -3x/4 + ?
-3x/4 = Right 4, Down 3 on a graph
( 3, 4)
-4 +3
Also goes thru the point (-1, 7)
+1 -3/4
(0, 25/4 or 6.25)
y = -3x/4 + 25/4

The diagram shows a playground in the shape of a trapezium.
50 m
U
32m
90 m
Work out the area of the playground.
Answer:
[tex] 2240 {m}^{2} [/tex]Step-by-step explanation:
Given,
Parallel sides of the trapezium = 50m, 90m
Height of the trapezium = 32m
Therefore,
Area of the trapezium
[tex] = \frac{1}{2} \times sum \: of \: parallel \: sides \: \times \: height[/tex]
[tex] = \frac{1}{2} \times (50 + 90)m \times 32m[/tex]
= (50 + 90) m × 16m
= 140m × 16m
[tex] = 2240 {m}^{2} (ans)[/tex]
Answer:
A = 2240 m²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 32 , b₁ = 90 and b₂ = 50 , then
A = [tex]\frac{1}{2}[/tex] × 32 × (90 + 50) = 16 × 140 = 2240 m²
What is the volume of the rectangular prism?
somebody help me please in the photo
Answer:
93 degrees
Step-by-step explanation:
alternate interior angles are congruent so 39+x=132 x=93
Answer:
Step-by-step explanation:
According to Alternate Interior Angles Theorem (in a graph that shows a transversal crossing two parallel lines, the alternate interior angles are congruent), The angle that includes the sum of 39° and x° is congruent to 132°.
So: 39° + x° = 132°, and x = 93

Based on these results, express the probability that a seventh grader chosen at
random will play the drums as a decimal to the nearest hundredth.
Answer:12/77
Step-by-step explanation:
The probability that a seventh grader chosen at random will play an instrument other than the Guitar is 0.76.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,
P = (Favorable event) / (Total event)
The total event for seventh grade is given as,
Total = 9 + 9 + 11 + 9
Total = 38
The probability that a seventh grader chosen at random will play an instrument other than the Guitar is calculated as,
P = 9/38 + 11/38 + 9/38
P = 29/38
P = 0.76

describe and correct the error in solving the equations below
9514 1404 393
Answer:
19. wrong multiplier was used, and used incorrectly; x = -324
20. wrong multiplier was used, and used incorrectly; y = 5
Step-by-step explanation:
In each case, the equation was multiplied by the coefficient of the variable, instead of divided. In each case, the square of the coefficient was evaluated incorrectly (so the error wasn't noticed).
__
19) As described above.
(-36)(9) = (x/9)(9)
-324 = x

20) In addition to the errors described above, the variable was changed from y to x.

Caroline puts $400 into a savings account that earns 6% annually. Write a function that represents this situation, where t is the time in years. Solve algebraically after how many years she will get $1200 in her account (round it to the nearest year).
Answer: 19 years
Step-by-step explanation:
Given
Amount invested [tex]\$400[/tex]
Rate of interest [tex]R=6\%[/tex]
after 1-year amount becomes
[tex]A=400\left (1+6\%\right)\\A=400\left (1+0.06\right)\\A=400\times 1.06\\A=\$424[/tex]
After n years it is
[tex]A=400\left (1.06\right)^n[/tex]
Sum accumulated is [tex]\$1200[/tex]
[tex]\Rightarrow 1200=400\left(1.06\right)^n\\\Rightarrow 3=\left(1.06\right)^n\\\text{Taking log both sides}\\\Rightarrow n=\dfrac{\ln 3}{\ln 1.06}\\\\\Rightarrow n=18.85\approx 19\ \text{years}[/tex]

[tex]YX = 40; XW = 41; WY = 9[/tex]
Required
Determine [tex]\cos(W)[/tex]
The question is illustrated with the attached image.
