There is a number such that 7 times the number minus 15 is equal to 41
Answer: 6.571
Step-by-step explanation: If you want the exact answer, it’s 6.57142857
Answer:
8 is the number
Step-by-step explanation:
So in order to find out the "number" we are going to have to turn the equation around. First of all the equation says "minus 15 is equal to 41" so we are going to add 15 to 41:
41 + 15 = 56
So now we are going to divide 7 from 56 because we are doing the equation backwards:
56/7 = 8
So now we check our work by replacing the number in the sentence with eight, "7 times 8 minus 15 is equal to 41" which would make the equation look like this:
7 * 8 + 15 = 41
First we multiply 7 by 8:
7 * 8 = 56
Now we subtract 15 from 56:
56 - 15 = 41
Making the equation look like this:
41 = 41

A store buys an item for $94. The store then prices the item to sell to customers. What is the selling price (in dollars) the store sells the item to customers for after applying a 62% markup? If necessary, round the answer to the closest hundredth.
Answer:
$152.28
Step-by-step explanation:
In order to determine the markup, multiply the original price by 62%
94 x 62% = 94 x .62 = 58.28
In order to determine the sale price, add the markup to the original price.
94 + 58.28 = $152.28
You can represent the measures of an angle and its complement as tº and (90 – x)". Similarly, you can represent the measures of an angle and its supplement as x° and (180 – x)". Use these expressions to find the measures of the angles described.
1. The measure of an angle is three times the measure of its supplement.
2. The measure of the supplement of an angle is three times the measure of its complement.
3. The measure of an angle increased by 20° is equal to the measure of its complement.
Answer:
180° - t = 5 · ( 90° - t )
180° - t = 450° - 5 t
5 t - t = 450° - 180°
4 t = 270°
t = 270° : 4
t = 67.5°
The measure of an angle is 67.5°.
Its complement angle: 22.5°.
Its supplement angle: 112.5°
112.5° = 5 x 22.5°

What are similar triangles?Similar triangle are those which have two pairs of interior corresponding angles are equal.
We have,
Two triangles as shown in the given figure,
Now,
Both the given triangles have 90° corresponding angles and also the opposite angle of 90° of both triangles is equal.
So,
Using triangle similarity rule,
i.e.
Sides are in equal proportion,
i.e.
[tex]\frac{49}{x} =\frac{14}{2}[/tex]
⇒
14x = 49 × 2
14x = 98
[tex]x=\frac{98}{14}[/tex]
x = 7
Hence, we can say that the value of x in the given diagram will be 7.

john drops a probe into a lake. the elevation of the probe changes by -1 1/2 feet every second. the probe takes 50 seconds to reach the bottom of the lake. how deep is the lake show your work
Answer:
The lake is 75 ft deep
Step-by-step explanation:
Here , we want to get the depth of the lake
mathematically, we can have this as the rate at which the elevation of the probe changes multiplied by the time it took the probe to reach the bottom of the lake
That would be;
3/2 * 50 = 75 feet

Given the function f (x) = x² + 5, evaluate f (-10)
Answer:
f(-10)=105
Step-by-step explanation:
When something says f(x), the (x) is your plugin value. So basically in this scenario, x= -10
1) f(-10)= (-10)^2+5
2)f(-10)= 100+5
3) f(-10)= 100+5
Ok hopefully I remembered my properties of exponents correctly, but I'm pretty sure that's the answer. If it isn't, you should try making the 100 negative instead of positive from step 2 and work from there.
What are the correct answers?

Answer:
1) C=80°
2) A=C= 54°
Step-by-step explanation:
1) 180-60-40=80
2)180-72=108
108/2=54
Hope this helps! :)
Answer:
1. 80º
2. Both are 54º
Step-by-step explanation:
1. If you add 60º + 40º in problem 1, you get 100º. We need to get it to equal 180º, so this means the missing angle would be 80º
2. Just like in the first one, we need this to equal 180º. So, let's go backwards.
180 - 72 = 108
Now, since the remaining angles are equal, let's divide 108º by 2
108 / 2 = 54º
Hope this helps :)
