Answer:

24 Newtons

Step-by-step explanation:

Force = mass x acceleration, or F = ma

so, Force = 24.0 kg*m/s²

That unit - kg*m/s² - is known as a Newton

Answer:

See explanation

Step-by-step explanation:

Consider triangles ABC and DEC. In these triangles,

$\overline{BC}\cong \overline {EC}$ - given
$\overline{AC}\cong \overline {DC}$ - given;
$\angle ACB\cong \angke DCE$ as vertical angles.

So,

$\triangle ABC\cong \triangle DEC$ by SAS postulate (two sides and angle between these sides of one triangle are congruent to two sides and angle between these sides of another triangle, so triangles are congruent).

Congruent triangles have congruent corresponding parts, hence,

$\overline{BA}\cong \overline{ED}$

What is the solution of the equation?<br> A. –5, 11<br> B. 5<br> C. 11<br> D. –11

rjkz [21]

Answer:

The solution is -5 or 11

Step-by-step explanation:

We are given the equation;

$4(3-x)^\frac{4}{3}-5=59$

We are supposed to solve the equation;

Taking 5 to the other side;

$4(3-x)^\frac{4}{3}=59+5$

$4(3-x)^\frac{4}{3}=64$

Dividing both sides by 4

$(3-x)^\frac{4}{3}=\frac{64}{4}$

$(3-x)^\frac{4}{3}=16$

We can cube both sides;

$((3-x)^\frac{4}{3})^3=16^3$

$(3-x)^4=4096$

Then we can get the fourth root on both sides of the equation;

$\sqrt[4]{ (3-x)^4} =\sqrt[4]{4096}$

We get;

$3-x=+8 or -8$

Solving for x

$3-x=8 and 3-x=-8$

Therefore;

$x=-5 or 11$

Therefore, the solution is -5 or 11

When a number is increased by 7.1%, the result is 89. What is the original number to the nearest tenth?

balu736 [363]

Answer:

The original number is $83.1$

Step-by-step explanation:

Let

x -----> the original number

Remember that

$100\%+7.1\%=107.1\%=107.1/100=1.071$

The increased number is equal to multiply the original number by the factor 1.071

$89=1.071x$

Solve for x

Divide by 1.071 both sides

$x=83.1$
