Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Max makes bread that calls for 7/8 cup of raisins per loaf. He has 5 1/4 cups of raisins. How many loaves of bread can he make?
The answer is 6 1/2 loaves. True or False?
Answers
Answer:
False.
Step-by-step explanation:
The answer is NOT 6 1/2 loaves it is 6 loaves.
Knowing that there Max has 5 1/4 cups of raisins and each loaf requires 7/8 cup of raisins, we would need to divide.
Let's turn the 5 1/4 into an improper fraction so when we divide the two fractions, it would be easier!
To turn 5 1/4 into an improper fraction we need to...
5 x 4 = 20
20 + 1
21/4
Now we divided 21/4 by 7/8.
When dividing fractions remember the rule: KEEP CHANGE FLIP!
We keep the first fraction...which is 21/4 in this case
Change the sign from division to multiplication
21/4 x 7/8
And flip 7/8 so it becomes 8/7
21/4 x 8/7
= 168/28
= 6 loaves
So, the answer is not 6 1/2 loaves (false!)
Answer:
False
Step-by-step explanation:
Given :
\(\frac{7}{8}\) Cup of Raisin per loaf
Have \(5\frac{1}{4}\) Cup of Raisin
Calculation steps:
\(\frac{21}{4}\) ÷ \(\frac{7}{8}\)
=
\(\frac{21}{4}\) × \(\frac{8}{7}\)
=
\(\frac{21 x 8}{4 x 7}\)
=
\(\frac{168}{28}\)
=
\(\frac{168 / 28}{28/28}\)
= \(6\)
Further explanation
For the problem:
21 /4 ÷7/ 8 = ?
Division of fractions is equivalent to multiplication by the reciprocal of the second fraction:
21 /4÷7 /8 =21/ 4 ×8/ 7
Once rearranged, multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:
\(\frac{21x8}{4x7} =\frac{168}{28}\)
The Greatest Common Factor (GCF) of 168 and 28 is 28. The result can be simplified by dividing both the numerator and denominator by 28.\(\frac{168}{28}=\frac{168/28}{28/28} =6\)
Therefore the result is: 6

Answer:
1. C
2. 55°
Step-by-step explanation:
So, we know that for an angle with its vertex inscribed on the circle, the arc it opens up to is twice the angle's measure, so we can get m∠ADE = 1/2(measure of arc AE), which is C.
Now we can input the measure of arc AE into the equation. So, m∠ADE = 1/2 * 110, and we can find out that m∠ADE = 55°.

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answers
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143
Look at this square. Find the value of a.
Answers
Answer:
18
Step-by-step explanation:
A square has 4 sides of equal length.
The perimeter of the square is the sum of the lengths of the sides of the square.
P = perimeter; a = length of 1 side
P = a + a + a + a
P = 4a
We are told the perimeter is 72 yd.
4a = 72 yd
Divide both sides by 4.
a = 72/4 yd
a = 18 yd

The first term of a geometric sequence is −8100 . The common ratio of the sequence is −0.1 .
What is the 6th term of the sequence?
Answers
Answer:
-8100 x (-0.1)5
Step-by-step explanation:
The 6th term of the sequence is -0.081.
What is geometric sequence?A geometric sequence can be defined as the sequence of numbers where any two consecutive terms have the same ratio. This ratio is called the common ratio of the sequence.
Given that,
The first term of the geometric sequence is, a₁ = -8100.
The common ratio is r = -0.1.
The general expression for the nth term is given as,
aₙ = a₁rⁿ⁻¹
Substitute n = 6 to obtain,
a₆ = -8100 × (-0.1)⁶⁻¹
= -8100 × (-0.1)⁵
= -0.081
Hence, the 6th term of the given sequence is -0.081.

Answers
The value of A/B is given as follows:
A/B = -2.
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:
B = -1 -> as x + B = 0 -> x = -B = -1.
When x = 0, y = -2, hence the value of A is obtained as follows:
A/-1 = -2
A = 2.
Then the division is given as follows:
A/B = 2/-1 = -2.
