I need help will give brilenst Write an expression where you multiply 0.035 times a power of ten so that the product is greater than 1, but less than 100.
The required expression is:
0.035 × [tex]10^2[/tex] = 3.5 where the product is 1 < [tex]10^x[/tex] < 100.
To ensure that the product is greater than 1 but less than 100 when multiplying 0.035 by a power of ten, we need to find the appropriate exponent that will give us a result within this range.
Let's express 0.035 as a product of a number between 1 and 10 and a power of ten:
0.035 = 3.5 × [tex]10^{-2}[/tex]
Multiplying by a power of ten increases the value. We want the product to be greater than 1 but less than 100. So, we need to increase the exponent of ten until we reach a value within this range.
0.035 × [tex]10^x[/tex]
To ensure that the product is greater than 1, we need to increase the exponent enough to make the coefficient (3.5) greater than 1:
3.5 × [tex]10^x[/tex] > 1
[tex]10^x[/tex] > [tex]\frac{1}{3.5}[/tex]
[tex]10^x[/tex] > 0.29
To ensure that the product is less than 100, we need to find an exponent that doesn't increase the coefficient (3.5) too much:
3.5 × [tex]10^x[/tex] < 100
[tex]10^x[/tex] < [tex]\frac{100}{3.5}[/tex]
[tex]10^x[/tex] < 28.57
Now, we need to find the appropriate exponent x that satisfies both conditions. This exponent should make the product greater than 1 but less than 100.
To simplify, we can use the fact that [tex]10^1[/tex] = 10 and [tex]10^2[/tex] = 100:
[tex]\[ 10^0[/tex] < [tex]10^x[/tex] < [tex]10^2[/tex]
Now, we can choose any exponent between 0 and 2 that satisfies the inequality. For example, we can choose x = 1:
0.035 × [tex]10^1[/tex] = 0.035 × 10 = 0.35
The product of 0.035 multiplied by [tex]10^1[/tex] is 0.35, which is not greater than 1 but less than 100.
Putting x = 2,
0.035 × [tex]10^2[/tex] = 0.035 × 100 = 3.5
Here, the product is greater than 1 but less than 100.
The question is:
Write an expression to multiply 0.035 times a power of ten so that the product is greater than 1, but less than 100.

The vertex angle of an isosceles triangle measures 40°. What is the measure of a base angle?
The measure of base angle is [tex]$$\boxed{{{70}^ \circ }} if the vertex angle is {40^ \circ }$$[/tex] .
Further explanation:
Given:
Vertex angle of the isosceles triangle is [tex]{40^ \circ }[/tex] .
Explanation:
The triangle three sided close Figure.
There are three type of triangles.
1. Equilateral triangle
2. Isosceles triangle
3. Scalene triangle
Equilateral triangle has all sides equal and all the angles are equal.
Isosceles triangle has 2 sides equal to each other and the two base angles are equal to each other.
Scalene triangle has all sides unequal and the angles are also not equal to each other.
The sum of all the angles of the triangle is [tex]{180^ \circ }[/tex].
Consider the base angle as y.
The value of y can be obtained as follows,
[tex]\begin{aligned}y+y+40&=180\\2y+40&=180\\2y&=180-40\\2y&=140\\y&=\frac{{140}}{2}\\y&={70^ \circ }\\\end{aligned}[/tex]
The measure of base angle is [tex]$$\boxed{{{70}^ \circ}} if the vertex angle is {40^ \circ}$$[/tex].

Find the percent of a standard normal model found in the given region
Each month, a retail store awards a blue ribbon to its employee of the month. The probability that Chloe is the employee of the month is 29% in January and 49% in February. What is the probability that she is awarded a blue ribbon in both January and February?
14.21%
19.51%
10.00%
21.81%
Answer:
Option A. 14.21%
Step-by-step explanation:
The probability that Chloe is awarded the employee of the month in January
= 29% P (J) = 0.29
The probability that Chloe is awarded the employee of the month in February = 49% P (F) = 0.49
As we know that both events are independent so
P ( J & F ) = P (J) × P (F)
P = 0.29 × 0.49 = 0.1421 or 14.21%
Therefore the probability that she is awarded a blue ribbon in both January and February 14.21%
The general form of the equation of a circle is 7x2 + 7y2 − 28x + 42y − 35 = 0
The equation of this circle in standard form is
A. (x - 2)^2 + (y + 3)^2 = 5
B. (x - 2)^2 + (y + 3)^2 = 18
C. (x - 4)^2 + (y + 6)^2 = 24
D. (x + 4)^2 + (y - 6)^2 = 24
E. (x + 2)^2 + (y - 3)^2 = 35

A. (-14,21)

C. (2,-3)
D. (-4,6)

And it's radius is ___ units.
A. 5 1/2
B. 3(2 1/2)
C. 2(6 1/2)
D. 35 1/2
Answer:
The standard form equation is B.
The centre of the circle is B
The radius is B.
Step-by-step explanation:
Firstly, the equation can all be divided by 7:
(7x² + 7y²− 28x + 42y − 35) ÷ 7 =
x² + y² - 4x + 6y - 5 = 0
x² - 4x + y² + 6y - 5 = 0
Now add [tex]\frac{1}{2}* b[/tex]
0.5 * 4 = 2, 2² = 4 so 4
0.5 * 6 = 3. 3² = 9 so 9
(x² - 4x + 4) + (y² + 6y + 9) - 4 - 9 - 5 = 0
As the standard form of a circle is (x - a)² + (y - b)²= r² , we need to change this to this. Simply find a number that multiplies to 4 and adds to -4 ( -2 ) and a number that multitplies to 9 and adds to 6 (3):
(x - 2)² + (y + 3)²
Also, we need to subtract the square of the number inside the brackets, as this is completing the square:
-2 * -2 = 4
3 * 3 = 9
So we need to subtract 4 and 9, and 5 as that was in the original:
(x - 2)² + (y + 3)² - 4 - 9 - 5 = 0
To find the radius, we need to move this numbers over to the other side making them positives:
(x - 2)² + (y + 3)² = 4 + 9 + 5
(x - 2)² + (y + 3)² = 18
So the equation is B.The centre of the circle in (x - a)² + (y - b)² is [tex]a[/tex] and [tex]b[/tex]
So in this equation the centre is -2, 3. Which is B.The radius is the square root of whatever (x - a)² + (y - b)² equals, so the square root of 18 is the radius:
√18 = √9√2
= 3√2
= [tex]3 * (2x^{\frac{1}{2} } )[/tex]
So your answer is B.the cost of an item is 100% of its price. what number goes in place of ? in the addition problem?
The answer is 100 thats all you have to put trust me.

In the 1939 movie The Wizard of Oz, when the brainless Scarecrow is given the confidence to think by the Wizard(by merely handing him a diploma, by the way), the first words the Scarecrow utters are, “The sum of the square roots of any two side of an isosceles triangle is equal to the square root of the remaining side.” An isosceles right triangle is just a right triangle having both legs the same length. Supposed that an isosceles right triangle has legs each length of 3. What is the length of the hypotenuse? Is the Scarecrow’s assertion valid? This question illustrated the true value of a diploma without studying.
The equation that the scarecrow uttered can be expressed mathematically as:
sqrt (C) = sqrt (A) + sqrt (B)
where A, B, and C are the sides of the triangle
Since the triangle is an isosceles, therefore A = B and
sqrt (C) = 2 sqrt (A)
given that the measure of the leg is 3, A = 3, C is:
sqrt C = 2 sqrt (3)
sqrt C = 3.464
C = 12
In a any triangle, the sum of two sides must be greater than the third side, since in this case C > A + B therefore the Scarecrow is not correct because the correct relationship should be A + B > C.
To find the correct hypotenuse, we start with the Pythagorean equation:
C^2 = A^2 + B^2
So what the scarecrow mistakenly did was to ignore the “+” symbol during the square root. Taking the square root on both sides, the correct equation is:
C = sqrt (A^2 + B^2)
Calculate for C, since A = B = 3:
C = sqrt (3^2 + 3^2)
C = 4.24
So now A + B > C and this is now correct.
