Answers
Answer:
First option.
Step-by-step explanation:
Look at the position of letters, you don't really need to look at the picture.
BQRT ~ XZGJ means figure BQRT is similar to figure XZGJ and congruent angles are written in same order.
So first letter of BQRT is B and first letter of XZGJ is X.
That means that angle B is congruent to angle X.
You can write that as: ∠B ≅ ∠X
Second letter of BQRT is Q and second letter of XZGJ is Z.
Angle Q is congruent to angle Z.
∠Q ≅ ∠Z
And same for last two pairs of angles.
Final answer:
∡B ≅ ∡X, ∡Q ≅ ∡Z, ∡R ≅ ∡G, ∡T ≅ ∡J

b=17.75 ft
Step-by-step explanation:
We will answer this using Pythagorean Theorem.
Since the bottom of a ladder is 3 feet from the wall, and the ladder is 18 ft long, the ladder is the hypotenuse. Knowing pythagorean theorem (a^2+b^2=c^2), we can plug it in.
3^2 + b^2 = 18^2
9+b^2=324
b^2=315

A box has one red marble one blue marvel and four green marbles of the same shape and size Dan draws a marble randomly from the box places it and then draws another marble randomly what is the probability of drawing two green marbles in a row explain your answer
Answers
Answer: 1/16
Step-by-step explanation:
Given that there are 4 green marbles, when Dan takes a marble the first time, the probability is 1/4 as there are 4 green marbles. When he puts it back and draws another one, the probability is still 1/4 because Dan didn't take the marble out of the bag(this is known as with replacement)
∴ the total probability of drawing 2 green marbles with replacement is 1/4 × 1/4= 1/16

The sum of multiples of five from 10 to 75, inclusive.
Answers
The asked sum of multiples of five from 10 to 75, inclusive, is 595.
To find the sum of multiples of five from 10 to 75, inclusive, we can use the formula for the sum of an arithmetic series:
Sum = (n/2) * ([first term] + [last term])
Following the given case, the first term (a) is 10, the last term (l) is 75, and the common difference (d) between consecutive terms is 5 (since we are considering multiples of five).
The number of terms (n) can be calculated as:
n = (last term - first term) / common difference + 1
Let's calculate the number of terms first:
n = (75 - 10) / 5 + 1
n = 65 / 5 + 1
n = 13 + 1
n = 14
Now, we can determine the sum of the multiples of five:
Sum = (14/2) * (first term + last term)
Sum = 7 * (10 + 75)
Sum = 7 * 85
Sum = 595
Therefore, the asked sum of multiples of five from 10 to 75, inclusive, is 595.

-3(2t-1)=t+t+t+3 pls help
Answers
Answer:
t=0
Step-by-step explanation:
First, we expand everything. The left-hand side is -3(2t) - 1(-3), and we expand it to be -6t+3. The right-hand side is t+t+t+3, and we can reduce it to 3t+3. Now that we have both sides of the equation, we set them to each other.
-6t+3=3t+3 (subtract 3 on both sides)
-6t=3t (add 6t to both sides)
9t =0 (divide by 9)
t=0

The triangle and the trapezoid have the same area what is the base b of the triangle

The formula to calculate the area of a triangle:
1/2*a*h (a: base, h: height)
All inputs are given for trapezoid so let's first find the area of trapezoid then we can find the value of b:
1/2*(10+12)*7 = 77 cm^2 is the area of trapezoid
now for the area of triangle:
1/2*b*7 = 77 (it was given that the areas are equal)
first we multiply both sides by 2
7*b = 154 now divide both sides by 7
b = 22

What is the value of x in the figure below?
Answers
Answer:
The value of x in the figure is 3.5
Step-by-step explanation:
When we look at the figure, we see that AB and BC, are connected, to make a longer side of a triangle. We can also see that BC is dilated from AB. When dilating, we multiply or divide by a number, to get the extended or shortened length. (Just keep multiplication and division in mind) To get x, we can do the same that we did to get 2, from 4. From AB to BC it goes from 4 to 2.
To get 2 from 4, you must divide 4 by 2. So when we do the same thing to 7, we should get x.
7 / 2 = 3.5
The value of x in the figure is 3.5
[tex]\\ \rm\dashrightarrow \dfrac{4}{2}=\dfrac{7}{x}[/tex]
[tex]\\ \rm\dashrightarrow 2=\dfrac{7}{x}[/tex]
[tex]\\ \rm\dashrightarrow x=\dfrac{7}{2}[/tex]
