please help it's urgent.
Answer:
It is the second triangle.
Step-by-step explanation:
This is because the area of the square is given as 25^2 as the perpendicular, 144^2 as the base, and the hypotenuse is 169^2.
Length of the perpendicular = 5^2 (Because 25^2 / 5^2)
Length of the base = 12^2
Length of the hypotenuse = 13^2
So, the Pythagoras theorem is,
=> [tex]H^{2} = P^{2} + B^{2}[/tex]
=> [tex]13^{2} =12^{2} +5^{2}[/tex]
This is true, because, 13*13 = 12*12 + 5*5
=> 169 = 144 + 25
=> 169 = 169

Which expression shows the amount of tax on a t shirt that cost x dollars, if tax is 7%
Answer:
2nd option: 0.07
Step-by-step explanation:
100% in decimal form is 1.00. S0, 7 is really 0.07. Hope this helps. Mark brainliest if it does!
The expression which represents the amount of tax on a t-shirt that cost x dollars, if tax is 7% is 0.07x.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.
Given that,
Cost of t-shirt = x dollars
Tax is 7% which means tax is 7% of the cost of the t-shirt
7% of x ⇒ 7/100 × x = 0.007x
Hence "The expression which represents the amount of tax on a t-shirt that cost x dollars, if tax is 7% is 0.07x".

In one grade of 150 students, the ratio of boys to girls is 2 : 3.
How many boys are in that grade?
Answer:
60 boys are in the grade.
Step-by-step explanation: Since there are 150 students, we can divide that number by the combined ratio, which in this case is 5. Dividing 150 by 5 would yield 30 students. We can use this information to multiply the given number of boys in the ratio by 30, which would produce 60.
A rectangle has a length of (x + 4) centimeters and a width of 2/4 x centimeters. If the
perimeter is 35 centimeters, what is the length of the rectangle?
A: 3cm
B: 9cm
C: 13cm
D: 7cm
Answer:
C: 13cm
Step-by-step explanation:
Given;
length of the rectangle, L = (x + 4) cm
width of the rectangle, W = [tex]\frac{2}{4}x[/tex] cm
perimeter of the rectangle, P = 35 cm
The perimeter of a rectangle is given as;
P = 2(L + W)
Substitute the givens;
[tex]35 = 2[(x+ 4) + \frac{2x}{4} ]\\\\35 = 2[\frac{6x}{4} +4]\\\\35 = 3x+8\\\\3x = 27\\\\x = \frac{27}{3}\\\\x = 9[/tex]
Then, L = (x + 4) cm
L = (9 + 4) cm
L = 13 cm
Therefore, the length of the rectangle is 13 cm

A drawer contains 6 pink gloves and 5 yellow gloves. What is the probability that you select two pink gloves if you reach in the drawer and randomly grab two gloves without replacement?
1/11
1/30
2/11
3/11
1/15
Answer:
[tex]\dfrac{3}{11}[/tex]
Step-by-step explanation:
Given that:
A drawer contains 6 pink and 5 yellow gloves.
Two gloves are randomly drawn without replacement.
To find:
The probability that the two gloves drawn are both pink.
Solution:
First of all, let us have a look at the formula for Probability of an event E:
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
Here, number of favorable cases are to draw 2 pink gloves out of 6, which is equal to:
[tex]_6C_2 = \dfrac{6\times 5}{2} = 15[/tex]
Here, Total number of cases are to draw 2 gloves out of 11, which is equal to:
[tex]_{11}C_2 = \dfrac{11\times 10}{2} = 55[/tex]
Now, the required probability is:
[tex]P(2\ pink\ gloves) = \dfrac{15}{55}\\\Rightarrow P(2\ pink\ gloves) = \dfrac{3}{11}[/tex]
Therefore, the answer is:
[tex]\dfrac{3}{11}[/tex]
Determine two numbers that have a product of 40 but have a sum of 13.
Answer:
The two numbers are 8 and 5.
Step-by-step explanation:
Let consider x and y to be these two numbers.
So;
(x) * (y) = 40 ---- (1)
x + y = 13 ----- (2)
From (2), let x = 13 - y
Then;
(13 - y) * y = 40
13y - y² = 40
13y - y² - 40 = 0
-y² + 13y - 40 = 0
Multiply through by (-)
y² - 13y + 40 = 0
By factorization;
(y - 8) (y - 5) = 0
y = 8 or y = 5
CHECK:
8 * 5 = 40
8 + 5 = 13
Therefore, the two numbers are 8 and 5.

can someone teach me how to write this in standard form ?
Answer:
2x + 5y = 7
Step-by-step explanation:
Here, 2x = 7 - 5y is given
The Standard form of equation is
Ax + By = C
Here, Ax = 2x; By = -5y; C = 7
Now, we get
2x = 7 - 5y
2x + 5y = 7
Here we get Ax = 2x; By = 5y; C = 7
Thus, The Standard form of equation is
2x + 5y = 7

write an exponential equation for the graph.
Answer:
Step-by-step explanation:
Exponential equations can be written as
[tex]y = ab^x\\[/tex]
in this case,
a = 5000 (the starting amount)
we just have to find b
[tex]10000 = 5000b^4\\20000 = 5000b^8\\\\b^4 = 2\\b^8 = 4\\\\\\b = \sqrt[4]{2}[/tex]
[tex]y = 5000(\sqrt[4]{2})^x[/tex]

Kristi gets $10 a week from her parents if she washes the dishes after dinner every night. Kristi has saved up $30 over the last few weeks from her allowance. She wants to continue saving her allowance until she has enough money to buy the $7o bike she saw at the store last week. Assuming Kristi receives her allowance every week, write an equation that shows how many more weeks Kristi has to save her allowance to buy the bike, where w is the number of weeks. You can solve the equation to check your answer.
Answer:
10w = 70-40
Step-by-step explanation:
To get to $70, Kristi has to work 10w. She has already earned $30 and needs to earn the remaining in 10w. Thus,
10w = 70-30
10w = 40
w = 4
She needs to work for 4 more weeks to buy the bike.
Use the properties of exponents to simplify: 3^0 ≠ 1 True False
Answer:
True
Step-by-step explanation:
Bcuz, some thing's power 0is 1
According to the zero power rule of exponents, 3^0 = 1. The statement 3^0 ≠ 1 is FALSE.
What is the Zero Power Rule of Exponents?The zero power rule is a property of exponents which simply states that whatever base that is raised to the power of zero would always be equal to one, i.e., x^0 = 1.
We are given that 3^0 ≠ 1. Based on the zero power rule of exponents, this is FALSE because 3^0 = 1.
