Answer:
x = 51
Step-by-step explanation:
Supplementary angles total 180º
(2x + 4) + (x + 23) = 180
Combine like terms
3x + 27 = 180
Subtract 27 from both sides
3x = 153
Divide both sides by 3
x = 51
Answer:
Hello! x = 51
Step-by-step explanation:
OMG I CAN ANSWER FINALLY!
it is forming a supplementary angle meaning it will add up to 180 degrees
51 × 2 = 102 102 + 4 = 106
51 + 23 = 74
106 + 74 = 180 therefore x = 51 Hope that helps.
Find the height of a cuboid if it's length is 15cm, it's breath is 12cm and it's total surface are is 900cm
Answer: [tex]h=8.33\ cm[/tex]

The angle corresponding to each other of different triangle are equal.
What are similar triangle ?"Similar triangles are triangles that have the same shape, but their sizes may vary. All equilateral triangles, squares of any side lengths are examples of similar objects. In other words, if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion".
Here given,
[tex]\triangle JGR[/tex] is similar to triangle [tex]\triangle MST[/tex]

Round 0.18 to one decimal place,
Answer:
0.2
Step-by-step explanation:
When rounding to a certain place, check to see if the number to the left of that place is five or above. If it is, round up. If its not, round down.
Rounding 0.18 to one decimal place, we get the value of 0.2.
To round 0.18 to one decimal place, we need to look at the digit in the tenths place (the first digit after the decimal point).
In this case, the tenths place digit is 8. To round to one decimal place, we follow the general rounding rule: if the tenths place digit is 5 or greater, we round up; if it is 4 or less, we round down.
Since the tenths place digit in 0.18 is 8, which is greater than 5, we need to round up.
Thus, rounding 0.18 to one decimal place, we get:
0.2
The rounded value is 0.2, as it is the nearest value when rounded to one decimal place.
Therefore, 0.18 rounded to one decimal place is 0.2.

an insurance company offers a no-claims discount of 55% for drivers who have not had an accident for four years. if the discounted premium for such driver is £334 how much did the driver save
Answer:
Amount the driver saved = £408.22
Step-by-step explanation:
Let the original price be = x
Discount % = 55%
Given price after discount = £334
Price after discount = x - (55% of x )
[tex]334 = x - (\frac{55}{100} \times x)\\\\334 = \frac{100x - 55x }{100}\\\\334 \times 100 = 45x\\\\x = \frac{334 \times 100}{45} = 742.22[/tex]
Therefore original price = £742.22
Amount the driver saved = 742.22 - 334
= £408.22

Answer:
x = 46.7°
Step-by-step explanation:
We are given:
1.) Angle x
2.) Side opposite to angle x
3.) Hypotenuse
We have to find angle x, therefore Sin ratio would be used;
Sin(x) = Opposite / hypotenuse
Sin(x) = 4 / 5.5
x = Sin⁻¹(4/5.5)

There are two known issues with a certain model of new car. The first issue, A, occurs with a probability of P(A)=0.1. B is another known issue with the car. If it is known that either event occurs with a probability of P(A OR B)=0.93, and that both events occur with a probability of P(A AND B)=0.07, calculate P(B).
Answer:
[tex]P(B) = 0.90[/tex]
Step-by-step explanation:
Given
[tex]P(A) = 0.1[/tex]
[tex]P(A\ or\ B) = 0.93[/tex]
[tex]P(A\ and\ B) = 0.07[/tex]
Required
[tex]P(B)[/tex]
To do this, we make use of:
[tex]P(A\ or\ B) + P(A\ and\ B) = P(A) + P(B)[/tex]
Make P(B) the subject
[tex]P(B) = P(A\ or\ B) + P(A\ and\ B) - P(A)[/tex]
So, we have:
[tex]P(B) = 0.93 + 0.07 - 0.1[/tex]
[tex]P(B) = 0.90[/tex]
how many questions out of 42 do I need to get right to score 75?
Answer:
31 questions, but it's impossible to score 75%.
Step-by-step explanation:
It's impossible to get exactly a score of 75% out of 42 questions. However, you can get the next closest percentage, which is rounded up to 74% with 31 questions right out of 75.
This is because 31 / 42 = 0.738... You can round 0.738 to 0.74. Then multiply 0.74 by 100, which gives you 74. This means the closest score you can get to 75 is 74% with 31 questions.
You can also score 76% with 32 questions right out of 42 questions. This is because 32 / 42 = 0.761... You can round 0.761 to 0.76. Then multiply 0.76 by 100, which gives you 76.

Someone plz help its doe in 10 min
Answer:
The factors of x² - 3·x - 18, are;
(x - 6), (x + 3)
Step-by-step explanation:
The given quadratic expression is presented as follows;
x² - 3·x - 18
To factorize the given expression, we look for two numbers, which are the constant terms in the factors, such that the sum of the numbers is -3, while the product of the numbers is -18
By examination, we have the numbers -6, and 3, which gives;
-6 + 3 = -3
-6 × 3 = -18
Therefore, we can write;
x² - 3·x - 18 = (x - 6) × (x + 3)
Which gives;
(x - 6) × (x + 3) = x² + 3·x - 6·x - 18 = x² - 3·x - 18
Therefore, the factors of the expression, x² - 3·x - 18, are (x - 6) and (x + 3)

Solve for x. 4x-4< 8
AND 9x +5 > 23
is it a, b,c or d ?
Answer:
[tex] A)\displaystyle2 < x < 3[/tex]
Step-by-step explanation:
A compound inequality is an inequality that combines two simple inequalities
we are given that
[tex] \displaystyle 4x - 4 < 8 \ \: \text{and} \: \: 9x + 5 > 23[/tex]
solving x for the first equation:
[tex] \displaystyle 4x - 4 < 8[/tex]
add 4 to both sides:
[tex] \displaystyle 4x < 12[/tex]
divide both sides by 4 and since we are dividing both sides by a positive number the inequality won't swap
[tex] \displaystyle x < 3[/tex]
solving x for the second equation:
[tex] \displaystyle 9x + 5 > 23[/tex]
cancel 5 from both sides:
[tex] \displaystyle 9x > 18[/tex]
divide both sides by 9 and since we are dividing both sides by a positive number:
[tex] \displaystyle x > 2[/tex]
therefore by combining the equations we obtain:
[tex] \displaystyle\boxed{2 < x < 3}[/tex]
hence,
our answer is A)
Find the scale factor from Triangle ABC to Triangle DEF.
Answer:
The ratio of any two corresponding lengths in two similar geometric figures.
Step-by-step explanation:
You can see immediately that the length of each of the sides in triangle DEF is equal to the length of the corresponding side in ABC multiplied by “a”.
If you divide the length of DE by the length of AB:
a^2/a =a.
You get a scale factor of “a”
Work out the area of a circle whose diameter is equal to 14 cm.
Give your answer correct to 2 decimal places.
cm?
help
Given:
The diameter of the circle = 14 cm
To find:
The area of the circle.
Solution:
We have,
Diameter of the circle = 14 cm
We know that the radius of the circle is half of its diameter. So,
[tex]r=\dfrac{14}{2}[/tex]
[tex]r=7\text{ cm}[/tex]
The area of a circle is:
[tex]A=\pi r^2[/tex]
Substituting [tex]\pi=\dfrac{22}{7}, r=7[/tex] in the above formula, we get
[tex]A=\dfrac{22}{7}\times (7)^2[/tex]
[tex]A=22\times 7[/tex]
[tex]A=154[/tex]
Therefore, the area of the circle is 154 square cm.
