Answer:
53
Step-by-step explanation:
We can use the Pythagorean Theorem to find x.
Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
Where "a" and "b" represent the legs and "c" represents the hypotenuse of the right triangle.
Let's substitute the given lengths into the equation:
[tex]28^2+45^2=x^2\\784+2025=x^2\\x^2=2809[/tex]
Take the square root of both sides:
[tex]\sqrt{x^2}=\sqrt{2809}[/tex]
[tex]x=53[/tex]

Answer:
x > 125
Step-by-step explanation:
I'm not sure how much you know about solving equations, but solving inequalities is in many ways very similar.
In this inequality, to isolate x, we must multiply both sides of the inequality by 25. This will put x by itself with another number on the other side of the inequality symbol. 5 times 25 is 125, so our final inequality is x > 125.

Solve each proportion
Hello.
In order to solve a proportion, you should cross-multiply:
[tex]\displaystyle\frac{7}{x} =\frac{5}{9}[/tex]
Multiply 7 times 9 and 5 times x:
5x=63
Divide both sides by 5:
x=[tex]\displaystyle\frac{63}{5}[/tex]
Now let's solve the second proportion.
Multiply 8p times 6 and 12 times 15:
48p=180
Divide both sides by 48:
p=3.75

write an equation for the point 4,3
Answer:
y-3=3(x-4)
Step-by-step explanation:
Hi there!
We are given that a line intersects the points (4, 3), and (6, 9)
The slope of this line is 3
And we want to write an equation in point-slope form using (4, 3)
Point-slope form is written as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point
We already have one point of the equation filled out -- the [tex]y_1[/tex], which in this case, is 3;
Our current equation is:
[tex]y-3=m(x-x_1)[/tex] (n.b. I put m and [tex]x_1[/tex] as place holders)
Before we proceed though, let's label the values of the other things (m and [tex]x_1[/tex]) to avoid confusion:
[tex]x_1=4\\m=3[/tex]
Now we can substitute these into the equation:
y-3=3(x-4)
Hope this helps!

Jordan and Raj each bake 7 batches of muffins. Jordan makes 18 muffins per batch, and Raj makes 15 muffins per batch. They combine their muffins and put all of them into boxes. They fill as many boxes as possible with 6 muffins each. They place the remaining muffins in the last box.
Enter your answers in the boxes.
How many full boxes do they make, and how many muffins will be in the last box?
i cant understand it much.
Answer:
Step-by-step explanation: Jordan's batches have 18 muffins a piece he made 7 bathes so 7 times 18 equals 126 muffins. Raj's batches have 15 muffins per batch which he also makes 7 batches of so 7 times 15 is 105. The boys then add all their muffins together so 126 muffins plus 105 muffins is 231 muffins. They then have to divide the muffins into boxes that can hold up to 6 muffins each so you are dividing 231 divided by 6 so the answer is 38 full boxes and 3 muffins left in the last box ( I just took the test and that was the answer)

A bridge has a sign that says “Maximum Weight 6 Tons.” If a truck weighs 13,000 pounds, is it too heavy to cross the bridge?
Answer:
Yes
Step-by-step explanation:
1 ton = 2000 pounds
6 tons = 12000 pounds
13000>12000
The truck is 1000 pounds overweight so yes it is too heavy to cross the bridge.
Given the arithmetic sequence : 52, a, b, 67 . Find the value of a * b
Answer:
a=57 b=62
Step-by-step explanation:
u⁰=52
u¹=a
u²=b
u³=67
Use the explicit relation given by:
u(n)=u⁰+nd
where n is any term and d is the common difference.
u³=u⁰+3d
67=52+3d
3d=67-52
d=15/3
d=5
a=52+5=57
b=a+5=62
67=b+52=62+5=67 (just to make sure of the answer)

C 9 3/10
D 10 3/5
Answer:
It's B
Step-by-step explanation:
Multiple the denominator with the whole number, then take that number and add it with the numerator. So you'll have 12/5 x 19/4. Multiply the numerators with each other and the denominators with each other and you'll have 228/20. Divide 228 by 4 and you'll get 11 2/5.

The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as L = 10 log StartFraction I Over I 0 EndFraction, where I 0 = 10 Superscript negative 12 and is the least intense sound a human ear can hear. What is the approximate loudness of a rock concert with a sound intensity of 10–1?.
The approximate loudness of a rock concert with a sound intensity of 10⁻⁹ is 110 Db.
What is a logarithm?Logarithms are another way of writing exponent. A logarithm with a number base is equal to the other number. It is just the opposite of the exponent function.
The loudness (L) measured in decibels (Db), of sound intensity (I), measured in watts per square meter, is defined as
[tex]\rm L = 10 \ log \ \dfrac{I}{I_o}[/tex]
where [tex]\rm I_o = 10^{-12}[/tex] and is the least intense sound a human ear can hear.
The approximate loudness of a rock concert with a sound intensity of 10⁻¹ will be
[tex]\rm L = 10 \ log \ \dfrac{10^-^1}{10^{-12}}\\\\\rm L = 10 \ log 10^1^1\\\\L = 10*11\\\\L = 110[/tex]

4(2a + 3) < 3(a - 1)
Answer:
-3
Step-by-step explanation:
4(2a +3)<3(a - 1)
8a +12 <3a - 3
8a - 3a <-3 - 12
5a<-15
a<15 :5
a<-3
Answer:
Step-by-step explanation:
4(2a+3) =3(a-1)

8a+12 =3a-3
-12 on the 12 and -3
8a=3a-15
add 15 to the 15 and 8

What is the x-intercept of the line with this equation 1/3x +y=-15?
Enter your answer in the box.
(_,0)
Answer:
(-45,0)
Step-by-step explanation:
We know that the x intercept is the point where y equals '0' in an equation. Which means in a function including the y value as a variable, we can substitute 0 for y to get the x intercept!
Here's how you do it:
[tex]1/3x + y = -15\\y=0\\1/3x + (0) = -15\\1/3x = -15\\x = -45[/tex]
That makes the x intercept -45!
Hope I was of assistance! #SpreadTheLove <3
x- intercept = -45
Step-by-step explanation:
equation: 1/3x + y = -15
=> to find intercept, y=0
=> 1/3x + 0 = -15
=> 1/3x = -15
=> 1x = -15 × 3
=> x = -45 / 1
=> x = -45
