Pls anyone help help help its 9th grade math help!!!!

Answer:

20

Step-by-step explanation:

Answer:

To find an equal ratio, you can either multiply or divide each term in the ratio by the same number (but not zero). For example, if we divide both terms in the ratio 3:6 by the number three, then we get the equal ratio, 1:2.

Answer:

Add the ratio terms to get the whole. Use this as the denominator.  Eg: 1 : 2 => 1 + 2 = 3.

Convert the ratio into fractions. Each ratio term becomes a numerator in a fraction.  Eg: 1 : 2 => 1/3, 2/3.

Therefore, in the part-to-part ratio 1 : 2, 1 is 1/3 of the whole and 2 is 2/3 of the whole.

Answer:

I think is asa but if not sorry

The ASA congruence theorem best expresses the relationship showing that the triangles given are congruent to each other.

Two or more triangles are said to be congruent if and only if sides and angles of one triangle is equal to the corresponding sides and angles of another triangle.

Given are two triangles.

Two angles of each triangle are marked as 64° and 72°.

So we have two angles of one triangle is equal to corresponding two angles of another triangle.

We also have from the figure two sides are equal to each other and this side is the included side of the equal angles.

So two angles and an included side of one triangle is equal to corresponding two angles and included side of another triangle which is theorem of ASA congruence.

Hence the given two triangles are congruent by ASA congruence rule.

Step-by-step explanation:

(5.3 * 10³) - (8 * 10²)

= (5.3 * 10³) - (0.8 * 10³)

= 4.5 * 10³

= 4,500.

Answer:

[tex](5.3 \times {10}^{3} ) - (8 \times {10}^{2} ) \\ = (5.3 \times {10}^{3} ) - (0.8 \times {10}^{3} ) \\ = (5.3 - 0.8) \times {10}^{3} \\ = 4.5 \times {10}^{3} \\ = \boxed{4500}[/tex]

Answer:

S = 83 g and 650 kg.

Step-by-step explanation:

Gram (g)= 1000 kilograms (kg).

Jill (J)= 92000 + 250 kg.

J = 92250 kg

Sister (S) = J - (8000 + 600 kg)

S = 92250 - 8600 kg

S = 83650 kg.

S = 83 g and 650 kg.

Answer:

[tex]2\frac{3}{4}[/tex]

Step-by-step explanation:

We have to subtract the weight of the cat from the weight of the dog.

[tex]8\frac{1}{4} -5\frac{1}{2}[/tex]

The first issue here is that there is not a common denominator. I'm going to multiply that 1/2 by 2 to make it 2/4. The 5 does NOT change.

[tex]8\frac{1}{4} -5\frac{2}{4}[/tex]

Subtract the whole numbers first.

[tex]8\frac{1}{4} -5\frac{2}{4} = 3\frac{1}{4} -\frac{2}{4}[/tex]

Then, we'll convert the first term to an improper fraction. We can do that by multiplying the whole number by the denominator and adding that number to the numerator.

[tex]3\frac{1}{4} -\frac{2}{4} ==> \frac{13}{4} - \frac{2}{4}[/tex]

Solve.

[tex]\frac{13}{4} -\frac{2}{4} = \frac{11}{4}[/tex]

Then, convert to a mixed number by dividing 11 by 4 and leaving the remainder in the numerator and putting the quotient in front as the whole number.

[tex]\frac{11}{4} ==> 2\frac{3}{4}[/tex]

So, the answer is [tex]2\frac{3}{4}[/tex]

Answer:

errr polynomials ahaha

so basically we can multiply the power outside of the parantheses with the exponents on the inside:

so

[tex]-3x^{2*4} y^{1*4}[/tex]

this will give us:

-3x^8y^4

we also unfortunately, have to use the power on the coefficient -3 as well  and we cant just MULTIPLY -3 by 4, we are going to have to multiply -3 with -3 4 TIMES(anytime we see a coefficient we MUST multiply the coefficient by itself according to the number outside of the parantheses)

so:

-3*-3*-3*-3=81

final expression

[tex]81x^{8}y^{4}[/tex]

Answer:

One equation could be y = -7x

Step-by-step explanation:
